Update for 10.9.1 patch

Summary:
**Context/Summary:**

Truncated range deletion in input files can be output by CompactionIterator with type kMaxValid instead of kTypeRangeDeletion, to satisfy ordering requirement between the truncated range deletion start key and a file's point keys. There was a plan to skip such key in https://github.com/facebook/rocksdb/pull/14122 but blockers remain to fulfill the plan.

Resumable compaction is not able to handle resumption from range deletion well at this point and should consider kMaxValid type same as kTypeRangeDeletion for resumption. Previously, it didn't and mistakenly allow resumption from a delete range. That led to an assertion failure, complaining about lacking information to update file boundaries in the presence of range deletion needed during cutting an output file, after the compaction resumes from that delete range and happens to cut the output file shortly after without any point keys in between.

```

```

This PR simply prevents  MaxValid from being a resumption point like regular range deletion - see commit 842d66eb18ea67e965d6acb1fce12c18eeb778d2

Besides that, the PR also improves the testing, variable naming, logging in resumable compaction codes that were needed to debug this assertion failure - see commit https://github.com/facebook/rocksdb/pull/14184/commits/aecd4e7f971f6dd4df672d9e5f1409fe4747c561. These improvements are covered by existing tests.

Test Plan:
- The stress initially surfaced the error. Using the exact same LSM shapes and files that were used in stress test but in a unit test, I'm able to get a deterministic repro and confirmed the fix resolves the error.  This is the repro test https://github.com/hx235/rocksdb/commit/1075936e693c68c960761855900c53f5b894f57a

```
- Follow-up: I tried a couple time to coerce the truncated range delete from scratch in the unit test but failed doing so. Considering kMaxValid may not be outputted by compaction iterator anymore after https://github.com/facebook/rocksdb/pull/14122/files gets landed again (and obsolete the bug) ADN the simple nature of this fix 842d66eb18ea67e965d6acb1fce12c18eeb778d2 AND the worst case of such fix going wrong is just less resumption, I decided to leave writing a unit test to coerce truncated ranged deletion from scratch a follow-up. Maybe I will draw inspiration from https://github.com/facebook/rocksdb/pull/14122/files.

-# RocksDB Code Generation and Review Guidance
-
-This document provides guidance for generating and reviewing code in the RocksDB project, derived from analysis of code review feedback across hundreds of complex merged Pull Requests. Use this as a reference when writing code with AI assistants or conducting code reviews.
-
----
-
-## General Best Practices
-
-### Code Quality and Maintainability
-
-**Clarity and Readability:** Write clear, self-documenting code. Use meaningful variable names, add comments for complex logic, and structure code to minimize cognitive load. Avoid clever tricks that sacrifice readability for marginal performance gains unless absolutely necessary. Avoid static_cast, reinterpret_cast, and C-style casts; static_cast_with_check, up_cast, and lossless_cast from cast_util.h are preferred.
-
-**Consistent Style:** Follow existing code style conventions. RocksDB uses `.clang-format` for formatting, specific naming conventions, and structural patterns. Deviations from these patterns are frequently flagged in reviews.
-
-**Error Handling:** Ensure robust error handling throughout the codebase. Use RocksDB's `Status` type consistently, propagate errors appropriately, and avoid silently ignoring failures. Reviewers pay close attention to edge cases and failure modes.
-
-### Testing Philosophy
-
-**Comprehensive Coverage:** Every change should include appropriate test coverage. This includes unit tests for isolated functionality, integration tests for component interactions, and stress tests for concurrency and performance validation. Reviewers will ask for additional tests if coverage is insufficient.
-
-**Edge Cases and Failure Modes:** Tests should explicitly cover edge cases, boundary conditions, and potential failure scenarios. This is especially important for changes affecting core database operations, compaction, or recovery logic.
-
-**Platform-Specific Testing:** RocksDB supports multiple platforms (Linux, Windows, macOS) and compilers (GCC, Clang, MSVC). Changes should be tested across relevant platforms, particularly when touching platform-specific code or using compiler-specific features.
-
-### Performance Considerations
-
-**⚠️ PERFORMANCE IS CRITICAL:** RocksDB is a high-performance storage engine where every CPU cycle and memory access matters. When writing code, always evaluate from a performance perspective. This is not optional—performance-aware coding is a fundamental requirement for all contributions.
-
-**Benchmarking and Profiling:** Performance claims should be backed by empirical evidence. Use RocksDB's benchmarking tools (e.g., `db_bench`) to validate improvements. Reviewers will request benchmark results for changes that could impact performance.
-
-**Memory Allocation:** Minimize dynamic memory allocations, especially in hot paths. Prefer stack allocation over heap allocation. Reuse buffers when possible. Consider using arena allocators or memory pools for frequent small allocations. Every `new`, `malloc`, or container resize has a cost.
-
-**Memory Copy:** Avoid unnecessary memory copies. Use move semantics, `std::string_view`, `Slice`, and pass-by-reference where appropriate. Be aware of implicit copies in STL containers and function returns. Prefer in-place operations over copy-and-modify patterns.
-
-**CPU Cache Efficiency:** Design data structures and access patterns to be cache-friendly. Keep frequently accessed data together (data locality). Prefer sequential memory access over random access. Be mindful of cache line sizes (typically 64 bytes) and avoid false sharing in concurrent code. Consider struct packing and field ordering to improve cache utilization.
-
-**Loop Optimization:** Look for opportunities to collapse nested loops, reduce loop overhead, and minimize branch mispredictions. Hoist invariant computations out of loops. Consider loop unrolling for tight inner loops. Batch operations when possible to amortize per-operation overhead.
-
-**SIMD and Vectorization:** Leverage SIMD instructions (SSE, AVX) for data-parallel operations when appropriate. Structure data to enable auto-vectorization by the compiler. Consider explicit SIMD intrinsics for critical hot paths like checksum computation, encoding/decoding, and bulk data processing.
-
-**Branch Prediction:** Minimize unpredictable branches in hot paths. Use `LIKELY`/`UNLIKELY` macros to hint branch prediction, e.g. for error cases and other rare or otherwise costly cases, but NOT for predicting popular configurations. Consider branchless alternatives for simple conditionals. Order switch cases and if-else chains by frequency.
-
-**Memory and Resource Management:** Be mindful of memory allocations, especially in hot paths. Use RAII patterns, smart pointers, and RocksDB's memory management utilities appropriately.
-
-**Hot Path Analysis:** When deciding how aggressively to optimize code, consider whether it's on a hot path:
-- **Hot path** (executed thousands+ times, e.g., data access, iteration, compaction loops): Performance is paramount. Apply all optimization techniques—loop collapsing, SIMD, cache optimization, pre-allocation, etc. The cost of each operation is multiplied by execution frequency.
-- **Cold path** (executed rarely, e.g., DB open, configuration parsing, error handling): Maintainability and clarity are more important. Prefer readable code over micro-optimizations. Complex optimizations here add maintenance burden with negligible performance benefit.
-- **Warm path** (moderate frequency): Balance both concerns. Use profiling data to guide optimization decisions.
-
-**Avoid Premature Optimization:** While performance is critical, focus on correctness first, then optimize based on profiling data. However, be performance-aware from the start—choosing the right algorithm and data structure upfront is not premature optimization. Use the hot path analysis above to decide how much optimization effort is warranted.
-
-### API Design and Compatibility
-
-**Backwards Compatibility:** RocksDB maintains strong backwards compatibility guarantees. Breaking changes are rare and require extensive justification. When deprecating features, follow the project's deprecation policy (typically spanning multiple releases).
-
-**API Consistency:** New APIs should be consistent with existing patterns. Use similar naming conventions, parameter ordering, and return types. Reviewers will suggest changes to improve consistency with the broader codebase.
-
-**Documentation:** Public APIs must be thoroughly documented, without unnecessary embelishment nor dwelling on implementation details nor project planning. When non-obvious, include usage examples, parameter descriptions, known bugs or limitations, notes on thread safety, performance characteristics, and compatibility considerations. Re-read comments for ambiguous terminology and phrasing, such as ambiguously re-purposed programming jargon.
-
----
-
-## Component-Specific Guidance
-
-### Database Core (`db`)
-
-The database core handles write-ahead logging (WAL), memtables, compaction, and recovery. This component receives the most scrutiny in code reviews.
-
-**Concurrency and Thread Safety:** Database operations are highly concurrent. Reviewers carefully examine locking strategies, atomic operations, and memory ordering. Document synchronization assumptions clearly. Use appropriate memory ordering semantics (`acquire`/`release` vs. `seq_cst`).
-
-**Compaction Logic:** Changes to compaction are complex and high-risk. Ensure that compaction logic respects configured parameters, handles edge cases (empty databases, single-file compactions), and maintains correctness under concurrent operations.
-
-**Error Propagation:** Database operations can fail in many ways (I/O errors, corruption, resource exhaustion). Ensure that errors are properly propagated, logged, and handled. Avoid assertions in production code paths.
-
-**Testing:** Database core changes require extensive testing, including unit tests, integration tests, and stress tests. Test with various configurations, compaction styles, and concurrent workloads.
-
-### Public Headers (`include`)
-
-Public headers define RocksDB's API surface. Changes here have the highest compatibility impact.
-
-**API Design:** New APIs should be intuitive, consistent with existing patterns, and well-documented. Consider how the API will be used in practice and avoid adding unnecessary complexity.
-
-**Backwards Compatibility:** Breaking changes to public APIs require extensive justification and a deprecation plan. Maintain ABI compatibility for bug fixes and patch releases.
-
-**Documentation:** Every public API must be thoroughly documented with usage examples, parameter descriptions, and notes on thread safety and performance characteristics.
-
-**Deprecation:** When deprecating APIs, follow the project's policy. Mark deprecated APIs clearly, provide migration guidance, and maintain support for at least one major release.
-
-### Internal Utilities (`util`)
-
-Internal utilities provide common functionality used throughout the codebase.
-
-**Code Reuse:** Utilities should be general-purpose and reusable. Avoid duplicating functionality that already exists elsewhere in the codebase.
-
-**Error Handling:** Utility functions should handle errors robustly and propagate them appropriately. Consider edge cases like overflow, underflow, and invalid inputs.
-
-**Testing:** Utility functions should have comprehensive test coverage, including edge cases and failure modes. Consider adding death tests for assertions.
-
-**Performance:** Utilities are often used in hot paths. Ensure that implementations are efficient and avoid unnecessary allocations or copies.
-
-### Table Management (`table`)
-
-Table management handles SST file format, block-based tables, and table readers/writers.
-
-**Block Format and Checksums:** Changes to block format require extreme care. Ensure that checksums are computed and verified correctly. Test with various compression algorithms and block sizes.
-
-**Iterator Correctness:** Table iterators are used throughout the codebase. Ensure that iterator semantics (Seek, Next, Prev) are correct, especially at boundaries and with deletions.
-
-**Caching and Prefetching:** Table readers interact with the block cache and prefetching logic. Ensure that cache keys are unique and that prefetching respects configured limits.
-
-**Performance:** Table operations are performance-critical. Benchmark changes that could impact read or write performance.
-
-### Utilities (`utilities`)
-
-Utilities include optional features like transactions, backup engine, and checkpoint.
-
-**Feature Isolation:** Utilities should be self-contained and not introduce unnecessary dependencies on core database internals.
-
-**Deprecation and Cleanup:** Legacy features are being phased out. When removing deprecated code, ensure that migration paths are documented and that users have sufficient warning.
-
-**Cross-Platform Compatibility:** Utilities often interact with OS-specific APIs. Ensure that code works on all supported platforms.
-
-### Options and Configuration (`options`)
-
-Options define RocksDB's configuration system.
-
-**Type Safety:** Use appropriate types for options (e.g., `uint32_t` for flags, scoped enums for enumerated values).
-
-**Deprecation Policy:** When deprecating options, follow the project's policy. Document the deprecation, provide migration guidance, and maintain support for at least one major release.
-
-**Dynamic Configuration:** Some options can be changed dynamically. Ensure that dynamic changes are thread-safe and take effect correctly.
-
-**Validation:** Validate option values and provide clear error messages for invalid configurations.
-
-### Cache (`cache`)
-
-Cache management is critical for RocksDB's performance.
-
-**Concurrency:** Cache operations are highly concurrent. Ensure that implementations are thread-safe and use appropriate synchronization primitives.
-
-**Performance:** Cache operations are in the hot path. Optimize for low latency and high throughput. Benchmark changes carefully.
-
-**Memory Management:** Cache implementations must manage memory carefully to avoid leaks and excessive allocations.
-
-**Eviction Policies:** Changes to eviction policies should be well-tested and benchmarked to ensure they improve overall performance.
-

-## Code Review Checklist
-
-When reviewing RocksDB code (or preparing code for review), use this checklist:
-
-### Contract Boundaries
-- [ ] Is each behavior owned by the right layer? High-level policy (for example,
-  "compaction wants this I/O mode") should live at the caller/policy layer, while
-  lower layers should expose generic mechanisms (for example, "open a fresh
-  reader", "skip shared cache insertion", or "use these FileOptions").
-- [ ] Do comments and names describe local contracts rather than leaking a
-  specific caller's rationale into reusable APIs? Generic code should not need to
-  know about one current use case unless the API itself is intentionally
-  use-case-specific.
-- [ ] Does each flag or parameter control one coherent behavior? If one boolean
-  starts implying ownership, cache policy, I/O mode, prefetching, and caller
-  identity, split it into explicit flags or an options struct.
-- [ ] Could a future caller use this lower-level API without accidentally
-  inheriting assumptions from compaction, backup, user reads, or a particular
-  table format? If not, tighten the contract with assertions, clearer names, or
-  a narrower API.
-- [ ] Are implementation details not being used as policy signals? Prefer an
-  explicit contract over inferring behavior from incidental fields such as file
-  options, cache handles, or current table-reader state.
-
-### Correctness
-- [ ] Does the change preserve database semantics (e.g., snapshot isolation, key ordering)?
-- [ ] Are all error cases handled appropriately?
-- [ ] Is the change thread-safe? Are synchronization primitives used correctly?
-- [ ] Are there any potential data races or deadlocks?
-
-### Testing
-- [ ] Does the change include appropriate test coverage?
-- [ ] Are edge cases and failure modes tested?
-- [ ] Have the tests been run on all supported platforms?
-- [ ] Are stress tests passing?
-
-### Performance
-- [ ] Are there benchmark results for performance-sensitive changes?
-- [ ] Does the change avoid unnecessary allocations or copies?
-- [ ] Are hot paths optimized appropriately?
-
-### API and Compatibility
-- [ ] Is the change backwards compatible?
-- [ ] Are new APIs consistent with existing patterns?
-- [ ] Is the public API documented?
-- [ ] Are deprecated features handled according to policy?
-
-### Code Quality
-- [ ] Does the code follow RocksDB's style conventions?
-- [ ] Is the code clear and maintainable?
-- [ ] Are comments and documentation sufficient?
-- [ ] Are there any code smells or anti-patterns?

-## Common Review Feedback Patterns
-
-The following patterns emerged as frequent sources of review feedback:
-
-1. **Test Coverage:** Reviewers frequently request additional tests for edge cases, platform-specific behavior, and failure modes. Complex changes require comprehensive test coverage including unit tests, integration tests, and stress tests.
-
-2. **Error Handling:** Ensure proper error propagation using RocksDB's `Status` type. Avoid silent failures and provide clear error messages that include context about what failed and why.
-
-3. **API Design:** New APIs should be consistent with existing patterns. Use descriptive names that follow established conventions. Avoid breaking changes without strong justification and a clear deprecation plan.
-
-4. **Documentation:** Public APIs must be documented with usage examples and notes on thread safety, performance characteristics, and compatibility considerations. Complex internal logic should also be well-commented.
-
-5. **Performance:** Performance-sensitive changes require benchmark results to validate improvements. Use `db_bench` and other profiling tools to measure impact. Avoid premature optimization that adds complexity without measurable benefit.
-
-6. **Concurrency:** Thread safety is critical in RocksDB. Document synchronization assumptions clearly. Use appropriate memory ordering semantics. Consider potential race conditions and deadlocks.
-
-7. **Code Style:** Follow existing conventions for naming, formatting, and structure. Use `.clang-format` for consistent formatting. Prefer scoped enums (`enum class`) over unscoped enums.
-
-8. **Backwards Compatibility:** RocksDB maintains strong compatibility guarantees. Breaking changes require extensive justification. When deprecating features, provide migration guidance and maintain support across multiple releases.
-
-9. **Refactoring:** Reviewers appreciate refactoring that improves code readability and maintainability. Look for opportunities to deduplicate code and simplify complex logic.
-
-10. **Platform Compatibility:** Ensure changes work correctly on all supported platforms (Linux, Windows, macOS) and with all supported compilers (GCC, Clang, MSVC).
-
-11. **Contract Boundary Leaks:** When a change plumbs a new option or use-case
-specific behavior through multiple subsystems, review the call chain for
-contract leaks. Caller-specific rationale belongs at the call site or public API
-documentation; reusable layers should expose precise, layer-local capabilities.
-Watch especially for comments mentioning one caller in generic code, booleans
-that silently bundle several behaviors, and downstream code inferring policy
-from an implementation detail instead of an explicit option.

-## Important tips
-
-### Build system
-* There are 3 build system. Make for git clones, BUCK (meta internal) for hg
-  clones, and CMake for some special cases.
-* When a new .cc file is added, update Makefile, CMakeLists.txt, src.mk, BUCK.
-* Don't manually edit BUCK file, after updating src.mk, run
-    /usr/local/bin/python3 buckifier/buckify_rocksdb.py to update it
-* For -j in make command, use the number of CPU cores to decide it.
-* When searching for references to something (a symbol, library, etc.), do not
-  restrict or truncate your search based on presumed relevance or scope. It is
-  important and time-saving to keep the repo reasonably consistent across
-  different build systems, programming languages, and even between
-  documentation and implementation.
-
-### Avoiding mixed build modes with Make (use `AUTO_CLEAN=1`)
-
-Object files are written to the same paths regardless of build flags, so
-reusing objects from a prior build with different flags causes confusing
-linker errors, etc. This problem is essentially avoidable by ALWAYS using
-`AUTO_CLEAN=1 make -j<n> <something>` for manual make invocations. This
-will automatically clean object files if the build parameters/flavor have
-changed. The `build_tools/rockstest.sh` / `rocksptest.sh` helpers described
-below set `AUTO_CLEAN=1` for you.
-
-`AUTO_CLEAN=1` does not fix Make failures associated with stale .d files
-referring to removed files. Resolve that manually or with `make clean`
-without complaining to the user.
-
-### Source checks
-* Run `make check-sources` before committing. This catches non-ASCII
-    characters in source files and other source-level issues that CI will
-    reject. In particular, **do not use Unicode characters** (em dashes,
-    smart quotes, etc.) in comments or strings -- use ASCII equivalents
-    (`--` instead of em dash, `'` instead of smart quote, etc.).
-
-### License headers
-* Every new source file needs a license header. For a file that does **not**
-    carry an outside/third-party copyright, use the standard Meta dual-licensed
-    header (the dual-license designation is required -- a bare
-    "All Rights Reserved" copyright is not an acceptable open-source header):
-    ```
-    //  Copyright (c) Meta Platforms, Inc. and affiliates.
-    //  This source code is licensed under both the GPLv2 (found in the
-    //  COPYING file in the root directory) and Apache 2.0 License
-    //  (found in the LICENSE.Apache file in the root directory).
-    ```
-    Use a `#` comment prefix instead of `//` for shell, Python, and Makefile
-    fragments.
-* Files derived from an external source (e.g. LevelDB) keep their original
-    upstream copyright line in addition to the header above.
-
-### RTTI and dynamic_cast
-* Production code and `db_stress` must build in **release mode
-    (`-fno-rtti`)**. Do not use `dynamic_cast` anywhere except unit tests.
-    Use `static_cast_with_check` from `util/cast_util.h` (validates with
-    `dynamic_cast` in debug builds, plain `static_cast` in release).
-* Unit tests (`*_test.cc`) are built in debug mode with RTTI enabled.
-
-### Cross-platform / portability
-Local `make` only exercises Linux with GCC/Clang, but CI
-(`.github/workflows/pr-jobs.yml` and `nightly.yml`) gates on a much wider
-matrix, so portability breaks are invisible locally until CI fails. Code must
-build (and where noted, run tests) across:
-
-| Axis | Must support |
-|------|--------------|
-| OS | Linux (x86_64 + ARM), macOS, Windows |
-| Architecture | Little-endian and big-endian targets, including Linux on s390x |
-| Compiler | GCC, Clang (libstdc++ **and** libc++), AppleClang, **MSVC (VS2022)**, MinGW (Linux cross-compile, build-only, no gflags) |
-| Build system | Make, CMake, and BUCK (internal) -- keep all in sync (see "Build system" above) |
-| Config | release (`-fno-rtti`), `ASSERT_STATUS_CHECKED`, ASAN/UBSAN/TSAN, folly, unity build, JNI/Java |
-
-Treat these as constraints to satisfy and infer the specifics from them before
-adding any system header, libc call, or compiler-specific construct. The most
-common trap: anything that compiles under GCC/Clang on Linux but not under
-**MSVC/MinGW** -- e.g. unguarded POSIX-only headers/functions (`<unistd.h>`,
-`<sys/*.h>`, `getpid`, `_exit`, ...) or GCC/Clang extensions
-(`__attribute__`, `__builtin_*`, VLAs, `alloca`). Prefer the `port::`/`Env`
-abstractions; otherwise guard with `#ifdef OS_WIN` (POSIX `<unistd.h>` ->
-Windows `<process.h>`). Because libc++ is also tested, include what you use
-rather than relying on libstdc++ transitive includes.
-
-Do not use `static_assert` to reject a supported architecture for an optional
-feature. Check an existing `port::` capability such as `port::kLittleEndian`
-and disable only the unsupported feature so the rest of RocksDB still builds.
-Use a portable representation when the feature itself must work across
-architectures.
-
-### Unit Test
-* After all of the unit tests are added, review them and try to extract common
-    reusable utility functions to reduce code duplication due to copy past between
-    unit tests. This should be done every time unit test is updated.
-* Don't use sleep to wait for certain events to happen. This will cause test to
-    be flaky. Instead, use sync point to synchronize thread progress.
-* Cap unit test execution with 60 seconds timeout.
-* To build and run unit tests locally, prefer these helper scripts:
-    * `build_tools/rocksptest.sh <test_binary> [more_binaries...] [args...]`
-        builds the binary(ies) with parallel make and `AUTO_CLEAN=1` and runs
-        them under gtest-parallel, sharding the test cases across CPUs. Prefer
-        this whenever running more than a couple of test cases, e.g.
-        `build_tools/rocksptest.sh table_test` or
-        `build_tools/rocksptest.sh db_test env_test --gtest_filter=*Foo*`.
-    * `build_tools/rockstest.sh <test_binary> [args...]` builds with parallel
-        make and `AUTO_CLEAN=1` and runs the binary directly (serially).
-        Use it only for a very small number of test cases, e.g.
-        `build_tools/rockstest.sh db_test --gtest_filter=*MixedSlowdown*`.
-* After writing a test, stress-test for flakiness (AUTO_CLEAN handles the
-    rebuild needed by the `COERCE_CONTEXT_SWITCH=1` flag change):
-    ```bash
-    COERCE_CONTEXT_SWITCH=1 build_tools/rockstest.sh {test_binary} -r100 \
-        --gtest_filter="*YourTestName*"
-    ```
-* For CI-style flaky tests that do not reproduce with `gtest_parallel.py`,
-    `--gtest_repeat`, or normal coerce-mode runs, inspect
-    `tools/gtest_parallel_repro.py --help`.
-* Each unit test file has overheads, so avoid creating new unit test files
-  for random minor features. Consider adding to slice_test, db_etc3_test, or
-  others.
-
-### Unit test dedup guidelines
-* Extract helper functions for repeated patterns such as object
-    construction, round-trip (encode → decode → verify), and common
-    assertion sequences.
-* Use table-driven tests (struct array + loop) when multiple test cases
-    share the same logic but differ only in input/expected data.
-* Prefer randomized tests over exhaustive parameter permutations. Use
-    `Random` from `util/random.h` (not `std::mt19937`). Use a time-based
-    seed with `SCOPED_TRACE("seed=" + std::to_string(seed))` so failures
-    are reproducible.
-* Keep deterministic edge-case tests separate from randomized tests
-    (error paths, boundary conditions, format verification).
-* Methods only used in tests should be private with `friend class` +
-    `TEST_F` fixture wrappers. In wrappers, always fully qualify the
-    target method to avoid infinite recursion.
-
-### Adding new public API
-    Refer to claude_md/add_public_api.md
-
-### Adding new option
-    Refer to claude_md/add_option.md
-
-### Removing deprecated option
-    Refer to claude_md/remove_option.md
-
-### Metrics
-* When adding a new feature, evaluate whether there is opportunity to add
-    metrics. Try to avoid causing performance regression on hot path when adding
-    metrics.
-
-### Stress test
-* When adding a new feature, make sure stress test covers the new option.
-
-### Component docs
-* For component-level design notes and implementation walkthroughs, start with
-    `docs/components/index.md`.
-* Documentation under `docs/components/` is organized by subsystem in
-    `docs/components/<area>/`.
-* Each subsystem directory should have an `index.md` entry point plus focused
-    chapter files for deeper topics.
-
-### DB bench update
-* When adding a performance related feature, support it in db_bench
-
-### Adding release note
-* Release note should be kept short at high level for external user consumption.
-    Release notes identify what users might care about most in a release. They
-    are not exhaustive and are not a guide. PLEASE learn from past agents who
-    ried to build elaborate release notes with implementation details and
-    elsewhere-documented nuance. That wastes time. Fight the bias that
-    "my change" is important so must be worthy of release note mention.
-* If more than single markdown line, consider how their formatting will be
-    integrated into HISTORY.md.
-
-### Blog posts (docs/_posts)
-* Blog post authors must be defined in `docs/_data/authors.yml` to be displayed
-
-### Final verification of the change
-* Execute `AUTO_CLEAN=1 make check` to build all of the changes and execute all
-    of the tests. `AUTO_CLEAN=1` ensures a clean rebuild if your previous build
-    used different parameters. Note that executing all of the tests could take
-    multiple minutes.
-* Run `AUTO_CLEAN=1 ASSERT_STATUS_CHECKED=1 make check` to verify all Status
-    objects are properly checked. This catches missing error handling that can
-    lead to silent data corruption.
-
-### Monitoring make check progress
-* Use `make check-progress` to get machine-parseable JSON progress while
-    `make check` is running. This is useful for Claude Code to monitor long
-    builds without timeout issues.
-* Run `make check` in background, then poll progress:
-    ```bash
-    AUTO_CLEAN=1 make check &
-    # Poll periodically:
-    make check-progress
-    ```
-* The output shows current phase and progress:
-    ```json
-    {"status":"running","phase":"compiling","completed":300,"total":919,...}
-    {"status":"running","phase":"testing","completed":1500,"total":29962,"failed":0,"percent":5,...}
-    {"status":"completed","phase":"testing","completed":29962,"total":29962,"failed":0,"percent":100,...}
-    ```
-* Phases: `compiling` -> `linking` -> `generating` -> `testing` -> `completed`
-* Key fields: `status`, `phase`, `completed`, `total`, `failed`, `percent`
-* When tests fail, `failed_tests` array shows details (up to 10 failures):
-    ```json
-    {"status":"running",...,"failed":3,"failed_tests":[
-      {"test":"cache_test-CacheTest.Usage","exit_code":1,"signal":0,"output":"...test log..."},
-      {"test":"env_test-EnvTest.Open","exit_code":0,"signal":11,"output":"...Segmentation fault..."}
-    ]}
-    ```
-* `exit_code`: non-zero means test assertion failed
-* `signal`: non-zero means test was killed (e.g., 9=SIGKILL, 6=SIGABRT, 11=SIGSEGV)
-* `output`: last 50 lines of test log including error messages and stack traces
-
-### Executing benchmark using db_bench
-* Since the goal is to measure performance, we need to build a release binary
-    using `AUTO_CLEAN=1 DEBUG_LEVEL=0 make db_bench`. If there is an engine
-    crash due to a bug, switch back to a debug build with
-    `AUTO_CLEAN=1 make dbg`; `AUTO_CLEAN=1` handles the release<->debug rebuild
-    automatically.
-
-### Formatting code
-* After making change, use `make format-auto` to auto-apply formatting without
-    interactive prompts (Claude Code friendly).

 # Rocksdb Change Log
 > NOTE: Entries for next release do not go here. Follow instructions in `unreleased_history/README.txt`
 
-## 11.9.1 (08/18/2026)
-### Public API Changes
-* Added an immutable `external_table_config` option that is persisted in OPTIONS files and passed to external table factories during bootstrap.
-
-## 11.9.0 (08/14/2026)
-### New Features
-* Added an integrated and improved compression auto-skip feature (new CompressionOptions, still experimental) that saves CPU by skipping compression when and where the overall ratio is inadequate. This improves on the previous auto-skip compression manager by (a) taking achieved compression ratios into account, (b) using a continuously evolving payoff estimate, and (c) combining natively with parallel compression.
-* Added the `blob_file_writable_file_max_buffer_size` mutable column family option. When set to a non-zero value, blob-file writers use it as their `WritableFileWriter` max buffer size instead of inheriting `DBOptions::writable_file_max_buffer_size`.
-* Added an experimental lazy wide-column read API, `DB::GetEntityLazy()` / `DB::MultiGetEntityLazy()` (see `include/rocksdb/lazy_wide_columns.h`). The returned `LazyWideColumns` leaves blob-backed columns as unresolved references and, like an iterator, stays valid after the call returns, so the caller resolves only the columns -- and only the byte ranges -- it needs; a byte-range read of an uncompressed blob (separate-file or embedded) reads just those bytes from storage. Adds `Env::IOActivity::kLazyResolve` and `rocksdb.blobdb.lazy.*` statistics. Requires `max_open_files == -1`.
-* Added DB property `rocksdb.num-running-remote-compactions`, reporting the number of compaction service jobs currently waiting in `CompactionService::Wait()`.
-* Added DB property `rocksdb.num-unscheduled-compactions`, reporting compactions waiting in the DB's internal compaction queue but not yet assigned to a background job.
-* Added `DB::AbortCompactions()` and `DB::ResumeCompactions()` for per-column-family compaction abort and resume, with the same active-abort semantics as the DB-wide `AbortAllCompactions()`/`ResumeAllCompactions()` but scoped to a single column family. Calls are reference-counted independently per column family and compose with the DB-wide abort.
-
-### Public API Changes
-* Add IndexFactory compatibility names for the existing user-defined index API.
-* Added the experimental `CoroDB` capability, exposed by `DB::GetCoroDB()`, with lazy native coroutine variants of `Get` and `MultiGet`. The existing `DB::GetAsync()` and `DB::MultiGetAsync()` APIs dispatch through it.
-* Added `rocksdb_batched_multi_get_pinned_cf()` to return batch-owned pinned MultiGet values and per-key errors without allocating one wrapper per found value.
-* Add `DBOptions::read_io_executor_threads` to increase the maximum thread count of the shared filesystem read I/O executor used for asynchronous reads when opening a DB. Opening a DB never reduces the shared executor thread count. Change the experimental `FSRandomAccessFile::SubmitReadAsync()` API to return whether the asynchronous path was used, and add the `FILE_SUBMIT_ASYNC_READ_FALLBACK` ticker to count calls that fall back to synchronous reads.
-* `ReadOptions::table_filter` is now a *pointer* to a caller-owned `std::function` instead of a `std::function` value, to improve efficiency in copying and destroying `ReadOptions` objects (which RocksDB does internally). This is a breaking change for users of this relatively obscure option, who will now need to declare a `std::function` that outlives the read. As a side effect of `ReadOptions` being trivially copyable, new but legitimate compiler warnings may surface.
-* Removed the experimental `CreateAutoSkipCompressionManager()`. Auto-skip compression is now a first-class feature of the block-based table builder, controlled by the new experimental `CompressionOptions::auto_skip`.
-* Added `CoroStackableDB` for implementing wrappers over native coroutine reads and used it to add coroutine `Get` and `MultiGet` support to `DBWithTTL` and WritePrepared `TransactionDB`. A stackable wrapper advertises coroutine support only when its wrapped DB supports it; TTL value decoding and transaction visibility semantics are preserved.
-* Added a `kSstFileWriter` value to `TableFileCreationReason`, which `SstFileWriter` now reports instead of the catch-all `kMisc`. This, along with new `db_name` and `is_remote_compaction` fields in `FilterBuildingContext`, improves the contextual information available to custom filter and compression strategies.
-* Renamed `TransactionLogIterator` to `WalIterator` (and `include/rocksdb/transaction_log.h` to `include/rocksdb/wal_iterator.h`), because it iterates the write-ahead log and is unrelated to `TransactionDB`. The old names still work. `DB::GetUpdatesSince()` is unchanged. In Java, `WalIterator` is the new name and `TransactionLogIterator` remains as a subclass. Also documented existing behavior that was previously unstated: only writes that reached the WAL are visible (so `WriteOptions::disableWAL` and `IngestExternalFile()` leave holes that end iteration), what each iterator state means, and that `GetUpdatesSince()` silently starts later when the requested sequence number is unavailable.
-
+## 10.9.1 (12/11/2025)
 ### Bug Fixes
-* Fixed a bug where `BlobFileBuilder` passed an SST path to `OnBlobFileCompleted()` instead of the completed blob path during BlobDB garbage-collection compactions, causing incorrect `SstFileManager` accounting and compaction failures on filesystems where the SST was not yet pathname-visible.
-
-### Performance Improvements
-* When `DBOptions::avoid_unnecessary_blocking_io` is true, obsolete `OPTIONS-*` files found during DB open are deleted by background purge instead of synchronously on the opening thread.
-
-## 11.8.0 (07/28/2026)
-### Public API Changes
-* Add callback-based asynchronous read APIs, `DB::GetAsync()` and `DB::MultiGetAsync()`. The idea is that when IO is required, RocksDB can suspend its internal coroutine read path, allowing the read executor thread to do other work. When the IO is complete, RocksDB invokes the user callback. This requires filesystem support for full performance benefits. A new filesystem API `FSRandomAccessFile::SubmitReadAsync()` is introduced for this. Unlike `ReadAsync`, the filesystem is responsible for eventually calling the callback. `FileSystem::GetReadExecutor()` returns the IO executor whose EventBases run coroutine read processing. In the Posix filesystem, an IO-uring based event loop is used to complete the IO.
-* Added `FlushOptions::listener_wait` (default `false`). When set together with `FlushOptions::wait == true`, `DB::Flush()` will not return until the registered `EventListener::OnFlushCompleted` callbacks for the flushed memtables have finished running. By default (`false`), `Flush(wait=true)` may return as soon as the flush result is committed, which can be before (or while) the `OnFlushCompleted` callbacks execute on the background flush thread. Also added the corresponding C API `rocksdb_flushoptions_set_listener_wait()` / `rocksdb_flushoptions_get_listener_wait()`.
-* Deprecated `PinnableWideColumns::serialized_size()` in favor of the new `PinnableWideColumns::payload_size()`, which returns the total size of the columns' names and values (for a plain value this equals the value size). Relatedly, wide-column read accounting changed subtly: read statistics for entities (`BYTES_READ`, `BYTES_PER_READ`, and the per-key byte counts for `GetEntity`/`MultiGetEntity`) and the `ReadOptions::value_size_soft_limit` threshold now measure entities by this payload size instead of the serialized entity size. This drops serialization framing bytes from those measurements (so reported/limited sizes for entity reads are slightly smaller than before) and makes plain-value and wide-column accounting consistent.
-
-### Behavior Changes
-* `ReadOptions::value_size_soft_limit` now also bounds the blob values resolved from pre-flush blob direct write references during `MultiGet`/`MultiGetEntity` (previously these were resolved after the limit check and read without bound). Enforcement is "always make progress": at least one key is read even if its value alone exceeds the limit, and only once the returned size exceeds the limit do subsequent keys get `Status::Aborted` -- so a caller retrying the aborted keys cannot loop forever on a single value that by itself exceeds the limit.
-
-### Performance Improvements
-* Reduced copying when reading wide-column entities that have blob-referenced columns, whether stored in separate blob files or embedded (same-file) as blob records in the same SST. On the point-lookup (`GetEntity`/`MultiGetEntity`) and blob-backed memtable/direct-write read paths, resolving these columns no longer re-serializes the whole entity into a fresh buffer: inline columns are referenced in place in the pinned entity and each resolved blob value is referenced in place from its fetched buffer. This is enabled by an internal change to `PinnableWideColumns` that lets its columns reference multiple backing buffers.
-
-## 11.7.0 (07/16/2026)
-### Public API Changes
-* Added `RangeLockManagerHandle::SetIsKilledCallback()`, a `std::function<bool()>` predicate polled during range-lock waits. When it returns true, a blocked `GetRangeLock()` wait returns promptly with `Status::Aborted()` instead of waiting for the lock timeout. Range-lock users that install no callback keep the original wait-until-grant-or-timeout behavior.
-* Added `MultiScanArgs::reverse` to support reverse MultiScan reads over bounded scan ranges.
-
-### Behavior Changes
-* When using `LockWAL()`, live-file capture APIs such as checkpoint and backup now flush WAL-disabled unpersisted data; they can block until `UnlockWAL()` or return `Aborted` when called from the same thread that holds `LockWAL()` to avoid deadlock. `UnlockWAL()` must now also be called from the same thread that called `LockWAL()`.
-
-### Performance Improvements
-* Fixed slow DB open with `best_efforts_recovery`, and slow catch-up of secondary and follower (read-only) instances, in which time and memory grew quadratically with the number of files in the DB (so the slowdown was worst for large DBs with long history).
-
-## 11.6.0 (07/02/2026)
-### New Features
-* Added EXPERIMENTAL embedded blob SST support through `SstFileWriter::OpenWithEmbeddedBlobs()`, storing eligible large values as same-file blob records in block-based SST files and resolving them transparently for reads. This niche feature currently supports uncompressed embedded blobs only; compression options are placeholders and compression support is deferred to follow-up work.
-
-### Public API Changes
-* Expanded the C API (`include/rocksdb/c.h`) with a large set of new `rocksdb_*` functions, mostly option getters/setters plus table-properties, job/event-listener, and metadata accessors, a WAL filter, a ReadOptions table filter, and a backup exclude-files callback. Many are now produced by a new semi-automated generator (`tools/c_api_gen/`) from the C++ headers; `include/rocksdb/c.h` remains a single self-contained header and the signatures of pre-existing functions are unchanged.
-
-### Bug Fixes
-* Reverted PR14831 that made range_lock_manager aware of reverse-order CF
-* Fixed a bug in `RandomAccessFileReader::ReadAsync` where an already-aligned direct-IO read request with a null `scratch` and a caller-provided `aligned_buf` would take the "already aligned" fast path and submit the null buffer to the underlying async read (e.g. a null iovec base to io_uring, failing with EFAULT). This could surface as spurious iterator failures during async prefetch (MultiScan with async IO) on direct-IO databases. The async path now allocates a backing buffer in this case, matching the synchronous `Read` path.
-* Fixed a bug where closing a read-only DB instance could delete live SST files created by a concurrent read-write DB sharing the same directory.
-
-## 11.5.0 (06/16/2026)
-### New Features
-* External table readers that open files through `ExternalTableOptions::fs` now update RocksDB SST/file-read statistics and file IO listener callbacks, making external file IO activity visible in existing read metrics.
-* Added `DB::PrepareFileIngestion()`, a two-phase form of `IngestExternalFile`/`IngestExternalFiles`. `PrepareFileIngestion()` performs all of the work that does not require the DB mutex (validating the arguments, reading each external file's metadata, and linking/copying the files into the DB) and returns an opaque `FileIngestionHandle`. `DB::CommitFileIngestionHandle()` (or `DB::CommitFileIngestionHandles()` for several handles at once) then makes the prepared files visible; multiple handles are committed atomically in a single MANIFEST write, or none are. `FileIngestionHandle::Abort()` (or simply destroying the handle) cancels a prepared ingestion and rolls it back. This gives flexibility to the application to Prepare a file separately from when its committed, and may shorten an applications critical path on `IngestExternalFile`.
-* Added two stats histograms reporting the per-call latency (in microseconds) of each successful `IngestExternalFile`/`IngestExternalFiles` call, split by phase: `rocksdb.ingest.external.file.prepare.micros` (argument validation and reading/validating/linking the external files, which does not block live writes) and `rocksdb.ingest.external.file.run.micros` (the ingestion performed under the DB mutex while live writes are blocked). Failed ingestions are not recorded.
-* Added `DBOptions::use_direct_io_for_compaction_reads` (default false). When enabled, compaction-input SST reads use `O_DIRECT` while user reads remain buffered, avoiding page-cache eviction of hot user-read data by sequential compaction scans. Pair with `use_direct_io_for_flush_and_compaction = true` on write-heavy workloads for direct I/O on both compaction inputs and outputs. Rejected at Open when combined with `allow_mmap_reads = true`. No-op when `use_direct_reads = true` is already set (since all reads are already direct).
-
-### Public API Changes
-* `DB::GetPreparedFileInfoForExternalSstIngestion()` can now prepare metadata for a live DB-generated SST file so it can be passed to `IngestExternalFileArg::file_infos`. The input path must exactly match a live table file owned by the source DB, and the returned metadata handle must outlive the ingestion.
-* `ExternalSstFileInfo` gained a `prepared_file_info` member produced by `SstFileWriter::Finish`, and `IngestExternalFileArg` gained a `file_infos` field: a vector of borrowed `const PreparedFileInfo*` pointers, parallel to `external_files`. The owning `ExternalSstFileInfo::prepared_file_info` handle must outlive the ingestion. When set, `IngestExternalFiles()` reuses the supplied per-file metadata instead of re-opening and scanning each file to recompute it, avoiding that extra I/O.
-* Corrected the public C++ option spelling from `memtable_veirfy_per_key_checksum_on_seek` to `memtable_verify_per_key_checksum_on_seek`. RocksDB continues to accept the old misspelled OPTIONS-file key for compatibility, while newly serialized OPTIONS files use the corrected key.
-* Added experimental read-scoped block buffer provider API, configured through `ReadOptions::read_scoped_block_buffer_provider`, for supported block-based table iterator scans and MultiScan reads to use caller-provided read-scoped storage for final data-block contents. When configured, supported provider-backed scan data-block reads bypass the data-block cache. The provider is ignored when mmap reads are enabled. RocksDB may still use ordinary temporary scratch for serialized block bytes, such as when a block may be compressed. Get and MultiGet do not currently provide API guarantees for this provider.
-* Added `FileSystem::SyncFile()` and `Env::SyncFile()` public APIs for syncing or fsyncing a file by name without requiring callers to reopen it as writable.
-
-### Behavior Changes
-* The default `compression` for column families is now `kLZ4Compression` rather than `kSnappyCompression`. This affects only column families that do not explicitly set `compression`, and only newly-written SST files. The change is fully compatible: existing data remains readable with no migration needed, as RocksDB selects the decompressor per block. LZ4 offers slightly better compression ratios and decompression CPU efficiency vs. Snappy and similar compression CPU, tested across various server CPUs. When support is not compiled in, the fallback path for default compression is LZ4 -> Snappy -> NoCompression.
-* Disable parallel compression (ignore `CompressionOptions::parallel_threads`) for fast built-in compressors: Snappy, LZ4 (accelerated, not LZ4HC), and accelerated levels of ZSTD (level < 0). These do not generally benefit from parallel compression. This behavior can be overridden with a custom Compressor from a custom CompressionManager.
-* `PosixFileSystem::OptimizeForCompactionTableRead` now delegates to the base `FileSystem::OptimizeForCompactionTableRead` implementation before applying its Linux-only compaction-readahead clamp (added for #12038). The returned `FileOptions::use_direct_reads` therefore reflects `DBOptions::use_direct_reads`, consistent with the base class and with other `FileSystem` implementations. Previously the override ignored the base implementation and keyed both the returned options and the Linux readahead clamp off the incoming `FileOptions` rather than `DBOptions`. At the in-tree call site the incoming `FileOptions::use_direct_reads` already matches `DBOptions::use_direct_reads`, so this is effectively a no-op for existing configurations; it removes a latent inconsistency where a caller passing `FileOptions` whose `use_direct_reads` disagreed with `DBOptions` would have had the global flag silently ignored for compaction-input reads on Linux. (Note: the `#12038` readahead clamp still keys off the global `use_direct_reads`; it is not skipped for the compaction-only `use_direct_io_for_compaction_reads` path, since that flag enables O_DIRECT after this hook runs.)
-* Brought more unity to `kLZ4Compression` and `kLZ4HCCompression` by giving each access to the other's compression levels. Negative (fast) values previously only available to LZ4 and positive (slow) values previously only available to LZ4HC are now available to both, so configuring a non-default `compression_opts.level` now selects the LZ4 compressor variant. This is a behavior change for previously tolerated but dubious configurations such as positive compression level with `kLZ4Compression`. `kLZ4Compression` and `kLZ4HCCompression` keep their effective default levels, equivalent to -1 and 9 respectively.
-* Removed a discontinuity in `kZSTD` compression levels at `compression_opts.level == 0` by mapping that setting to `level = -1` rather than to `level = 3` as the ZSTD library does internally. This improves the compression auto-tuning landscape.
-
-### Bug Fixes
-* Fixed a bug where the range lock manager would crash with an assertion failure when using a reverse comparator column family.
-
-### Performance Improvements
-* Reduced commit latency when ingesting many external files by allowing `IngestExternalFileOptions::file_opening_threads` to open table readers for committed ingested files using multiple threads.
-* Reduced commit latency for large external file ingestions into the last level by adding `IngestExternalFileOptions::prefetch_lmax_index_and_filter_blocks`, which can skip commit-time index and filter block prefetching for cache-backed table metadata.
-
-## 11.4.0 (06/02/2026)
-### Public API Changes
-* Added `rocksdb_options_set_memtable_batch_lookup_optimization()` and `rocksdb_options_get_memtable_batch_lookup_optimization()` to the C API, exposing the existing `AdvancedColumnFamilyOptions::memtable_batch_lookup_optimization` field. This allows C API users (and downstream language bindings) to enable the skip-list memtable's batch-lookup optimization for `MultiGet`, which caches the search path between consecutive keys and reduces per-key cost from O(log N) to O(log d) where d is the distance between consecutive keys.
-* Added `rocksdb_readoptions_set_optimize_multiget_for_io()` and `rocksdb_readoptions_get_optimize_multiget_for_io()` to the C API, exposing the existing `ReadOptions::optimize_multiget_for_io` field. This allows C API users (and downstream language bindings) to opt out of the multi-level parallel MultiGet path, which only takes effect when the library is built with `USE_COROUTINES`.
-* Added `rocksdb_block_based_table_index_block_search_type_auto` enum constant and the `rocksdb_block_based_options_set_uniform_cv_threshold()` setter to the C API. The constant exposes `BlockSearchType::kAuto`, and the setter exposes `BlockBasedTableOptions::uniform_cv_threshold`. Both are required for `kAuto` index-block search to take effect from the C API: without setting `uniform_cv_threshold >= 0`, the per-block `is_uniform` footer bit is never written, and `kAuto` falls back to binary search at read time.
-* Added `EventListener::OnDBShutdownBegin`, a callback that fires once when a DB begins shutdown, including when RocksDB cleans up a failed `DB::Open()` attempt.
-* Added a new PerfContext counter `blob_cache_read_byte` for blob cache bytes read.
-
-### Behavior Changes
-* Remote compaction now falls back to local compaction when the primary cannot deserialize a successful `CompactionServiceResult` before installing any remote output files.
-* StringToMap (rocksdb/convenience.h) now preserves the outer braces of nested values so each map entry is in self-contained form and can be embedded directly into another `key=value;` string (e.g. SetOptions) without losing inner ';' delimiters. A new symmetric MapToString utility is provided.
-
-### Bug Fixes
-* Fixed a bug where `AbortAllCompactions()` could leave automatic compaction work unscheduled when aborting before the background worker picked it, causing compaction and write stalls until DB restart.
-* Fix a bug where db had a false positive compaction corruption error due to remote compaction service result with `has_accurate_num_input_records=false` not being serialized.
-* Fixed WritePrepared TransactionDB cleanup after retryable commit or rollback write failures so prepared transactions remain rollbackable instead of leaving unresolved prepared state.
-* Fix a rare corruption bug for tiered compaction that incorrectly moved last level range tombstones into proximal level. This corruption error is surfaced when force_consistency_checks is enabled.
-
-### Performance Improvements
-* Reduce the likelihood of user-facing metadata operations blocking on MANIFEST rotation when file creation is slow, such as on remote storage. MANIFEST write batches containing foreground edits from `CreateColumnFamily()`, `DropColumnFamily()`, `CreateColumnFamilyWithImport()`, `IngestExternalFile()`, and `DeleteFilesInRanges()` now get a relaxed file size threshold for triggering MANIFEST rotation; background-only MANIFEST write batches, such as compaction and flush, continue to use the normal threshold. This change should make auto-tuning manifest file size more attractive (see `max_manifest_file_size` and `max_manifest_space_amp_pct` options).
-
-
-## 11.3.0 (05/15/2026)
-### New Features
-* Add experimental DB option `async_wal_precreate` to precreate the next WAL file in a background thread and reduce foreground WAL rotation latency. The option is sanitized to false when WAL recycling is enabled.
-* Added a new `EventListener::OnCompactionPreCommit` callback that fires after a compaction job finishes but before its input files are released (i.e. while `FileMetaData::being_compacted` is still true). Listeners that maintain bookkeeping of which files are currently being compacted can clean up such state in this new callback to avoid races with concurrent compaction picking, where another thread might pick up the same files for a new compaction immediately after `being_compacted` is flipped back to false but before `OnCompactionCompleted` fires. The default implementation is a no-op so this is not a breaking change.
-* Add mutable DBOption `optimize_manifest_for_recovery` (default false). When enabled, RocksDB can reduce recovery work after a clean shutdown, which may lower DB::Open latency on warm reopens.
-* Added public utility APIs `ParseCompressionNameForDisplay()` to convert `TableProperties::compression_name` into a human-readable compression name for both legacy and format_version 7+ SST metadata, including custom `CompressionManager`-provided display names for custom compression types.
-* Add `reuse_manifest_on_open` DBOption (default false). When enabled, DB::Open reuses the existing MANIFEST file for append instead of creating a fresh one, avoiding the cost of serializing the entire database state into a new MANIFEST on the first post-open write. To prevent this feature from interfering with manifest file size auto-tuning, an extra forward-compatible field is now always added to the MANIFEST (to track the last "compacted" size).
-
-### Behavior Changes
-* Read-only open with `error_if_wal_file_exists=true` now tolerates empty WAL files so empty precreated WALs do not prevent inspection.
-* WriteCommitted TransactionDB now matches WritePrepared and WriteUnprepared compaction filtering in both single- and two-write-queue modes: a compaction filter's FilterMergeOperand will not be invoked on merge operands at or below the latest published sequence number.
-
-### Bug Fixes
-* Fixed blob-backed wide-column merge reads to preserve correct status
-propagation and resolution across memtable, read-only, and secondary DB
-paths.
-* Fixed a bug where `DB::GetCreationTimeOfOldestFile()` could return inaccurate results instead of the real creation time when called shortly after opening a legacy DB (one whose manifest lacks `file_creation_time`) with `open_files_async = true`. The API now waits for background SST file loading to complete only when needed; modern DBs are unaffected.
-* Fixed merge reads against wide-column/blob-backed base values to preserve precise failure statuses, including `GetMergeOperands()` and direct-write memtable reads.
-* Fix bug in range tombstone synthesis that covers live keys added during an IngestExternalFile
-* Reject the empty string as a column family name in `DB::CreateColumnFamily` / `DB::CreateColumnFamilies`. Previously such calls returned OK and a usable handle, but the column family was not persisted in the manifest, so any data written to it was silently lost on DB reopen.
-* Fixed a bug where a WriteCommitted TransactionDB using commit-bypass WBWI ingestion could drop an entry that is still visible at the published sequence boundary.
-
-## 11.2.0 (04/18/2026)
-### New Features
-* Added experimental `DBOptions::fast_sst_open` option. When enabled, RocksDB retrieves opaque file system metadata for SST files after flush, compaction, and external file ingestion, persists it in the MANIFEST, and passes it back to the file system on subsequent file opens to accelerate DB open time.
-* Added new option `min_tombstones_for_range_conversion` in `AdvancedColumnFamilyOptions`. When set to a non-zero value N, forward or reverse iteration will convert N or more contiguous point tombstones into a range tombstone in the mutable memtable. Future read operations will then be able to benefit from range tombstone optimizations. There are some limitations when it comes to table_filters, prefix_filters, and UDTs. See header comments for more details.
-* Added read-triggered compaction: a new column family option `read_triggered_compaction_threshold` (default 0, disabled) that marks SST files for compaction when their read frequency (`num_collapsible_entry_reads_sampled / file_size`) exceeds the threshold. This helps reduce read amplification for frequently-read ("hot") keys. A new DB option `max_compaction_trigger_wakeup_seconds` (default 43200s / 12 hours) controls the maximum interval for periodic compaction score re-evaluation, which is necessary for this feature to work on quiet (no-write) databases.
-
-### Public API Changes
-* Added new `WideColumnBlobResolver` interface and `CompactionFilter::FilterV4()` method, including `ResolveColumn()` / `ResolveColumns()` helpers for lazy loading blob column values in wide-column entities during compaction. This allows compaction filters to resolve blob values on-demand, avoiding unnecessary I/O for blob columns they don't need to access.
-* Changed experimental feature `ExternalTableReader::Get` and `ExternalTableReader::MultiGet` to use `PinnableSlice` instead of `std::string` for output values, enabling zero-copy pinning. This will break existing implementations.
-* Added `SstFileReader::Get` and `SstFileReader::MultiGet` overloads that accept `PinnableSlice`/`std::vector<PinnableSlice>*`, enabling zero-copy reads when the underlying `TableReader` supports pinning.
-
-### Behavior Changes
-* Prefix filter changes - when seeking to a key that is out of domain, and total_order_seek is false, total_order_seek is treated as if it were true. When prefix_same_as_start = true, now iterating past a key that is out of domain invalidates the iterator. The existing behavior does not check for InDomain in the DBIter, so Transform() can produce undefined behavior (e.g. key of size 3 on FixedPrefixTransform(4)).
-* Wide-column entities with blob-backed columns now use a new V2 on-disk encoding; older RocksDB versions that do not support wide-column blob separation will reject DBs or SSTs containing those entities.
-
-### Bug Fixes
-* Fix blob garbage accounting for blob direct-write flushes so flush-time filtering and overwrite elision correctly register obsolete blob bytes in blob metadata.
-* Fix a memory accounting leak in IODispatcher where ReadIndex() moved block values out of ReadSet without releasing the associated prefetch memory, causing subsequent prefetches to be blocked when max_prefetch_memory_bytes was set.
-* Fix MultiScan to fall back to synchronous coalesced reads when async I/O is unsupported at runtime.
-
-
-## 11.1.0 (03/23/2026)
-### New Features
-* Add a new option `open_files_async`. The existing behavior is on DB open, we open all sst files and do basic validations. For very large DBs on remote filesystems with many ssts, this may take very long. This option performs these validations instead in the background. Open errors found by this async background task are surfaced as a new background error kAsyncFileOpen.
-* Added `BlockBasedTableOptions::kAuto` index block search type that automatically selects between binary and interpolation search on a per-index-block basis. During SST construction, each index block's key distribution uniformity is analyzed using the coefficient of variation of key gaps, and index blocks with uniform keys use interpolation search while others fall back to binary search. The uniformity threshold is configurable via `BlockBasedTableOptions::uniform_cv_threshold` (default: 0.2).
-* Introduced enforce_write_buffer_manager_during_recovery option to allow WriteBufferManager to be enforced during WAL recovery. (Default: true)
-* Add `memtable_batch_lookup_optimization` option to use batch lookup optimization for memtable MultiGet. For skip list memtables, after each key lookup, the search path is cached and reused for the next key, reducing per-key cost from O(log N) to O(log d) where d is the distance between consecutive keys. Benchmarks show ~7% improvement in memtable-resident MultiGet throughput.
-* Added `BlockBasedTableOptions::PrepopulateBlockCache::kFlushAndCompaction` to prepopulate the block cache during both flush and compaction. Compaction-warmed blocks are inserted at `BOTTOM` priority (vs `LOW` for flush) so they are evicted first under cache pressure. Recommended only for use cases where most or all of the database is expected to reside in cache (e.g., tiered or remote storage where the working set fits in cache).
-* Added new mutable DB option `verify_manifest_content_on_close` (default: false). When enabled, on DB close the MANIFEST file is read back and all records are validated (CRC checksums and logical content). If corruption is detected, a fresh MANIFEST is written from in-memory state.
-
-### Behavior Changes
-* num_reads_sampled now factors in re-seeks and next/prev() on file iterators for files in L1+. next/prev() is discounted by 64x compared to seek due to being a much cheaper call.
-* Remote compaction workers now skip WAL recovery when opening the secondary DB instance, since only the LSM state from MANIFEST is needed for compaction. This reduces I/O and speeds up remote compaction startup.
-
-### Bug Fixes
-* Fix a bug in round-robin compaction that missed selecting input files that are needed to guarantee data correctness and cause crashing in debug builds or silent data corruption in release builds for Get().
-
-## 11.0.0 (02/23/2026)
-### New Features
-* Added support for storing wide-column entity column values in blob files. When `min_blob_size` is configured, large column values in wide-column entities will be stored in blob files, reducing SST file size and improving read performance.
-* Added `CompactionOptionsFIFO::max_data_files_size` to support FIFO compaction trimming based on combined SST and blob file sizes. Added `CompactionOptionsFIFO::use_kv_ratio_compaction` to enable a capacity-derived intra-L0 compaction strategy optimized for BlobDB workloads, producing uniform-sized compacted files for predictable FIFO trimming.
-* Include interpolation search as an alternative to binary search, which typically performs better when keys are uniformly distributed. This is exposed as a new table option `index_block_search_type`. The default is `binary_search`.
-
-### Public API Changes
-* Added new virtual methods `AbortAllCompactions()` and `ResumeAllCompactions()` to the `DB` class. Added new `Status::SubCode::kCompactionAborted` to indicate a compaction was aborted. Added `Status::IsCompactionAborted()` helper method to check if a status represents an aborted compaction.
-* Drop support for reading (and writing) SST files using `BlockBasedTableOptions.format_version` < 2, which hasn't been the default format for about 10 years. An upgrade path is still possible with full compaction using a RocksDB version >= 4.6.0 and < 11.0.0 and then using the newer version.
-* Remove deprecated raw `DB*` variants of `DB::Open` and related functions. Some other minor public APIs were updated as a result
-* Remove deprecated `DB::MaxMemCompactionLevel()`
-* Remove useless option `CompressedSecondaryCacheOptions::compress_format_version`
-* Remove deprecated DB option `skip_checking_sst_file_sizes_on_db_open`. The option was deprecated in 10.5.0 and has been a no-op since then. File size validation is now always performed in parallel during DB open.
-* Remove deprecated `SliceTransform::InRange()` virtual method and the `in_range` callback parameter from `rocksdb_slicetransform_create()` in the C API. `InRange()` was never called by RocksDB and existed only for backward compatibility.
-* Remove deprecated, unused APIs and options: `ReadOptions::managed` and `ColumnFamilyOptions::snap_refresh_nanos`. Corresponding C and Java APIs are also removed.
-* Remove deprecated `SstFileWriter::Add()` method (use `Put()` instead) and the deprecated `skip_filters` parameter from `SstFileWriter` constructors (use `BlockBasedTableOptions::filter_policy` set to `nullptr` to skip filter generation instead).
-
-### Behavior Changes
-* Change the default value of `CompactionOptionsUniversal::reduce_file_locking` from `false` to `true` to improve write stall and reduce read regression
-
-### Bug Fixes
-* Fix longstanding failures that can arise from reading and/or compacting old DB dirs with range deletions (likely from version < 5.19.0) in many newer versions.
-* Fix a bug where WritePrepared/WriteUnprepared TransactionDB with two_write_queues=true could experience "sequence number going backwards" corruption during recovery from a background error, due to allocated-but-not-published sequence numbers not being synced before creating new WAL files.
-
-### Performance Improvements
-* Add a new table option `separate_key_value_in_data_block`. When set to true keys and values will be stored separately in the data block, which can result in higher cpu cache hit rate and better compression. Works best with data blocks with sufficient restart intervals and large values. Previous versions of RocksDB will reject files written using this option.
-
-## 10.11.0 (01/23/2026)
-### Public API Changes
-* New SetOptions API that allows setting options for multiple CFs, avoiding the need to reserialize OPTIONS file for each CF
-* Remove remaining pieces of Lua integration
-
-### Behavior Changes
-* The new default for `BlockBasedTableOptions::format_version` is 7, which has been supported since RocksDB 10.4.0 and is required in order to use CompressionManagers supporting custom compression types.
-
-### Bug Fixes
-* Fixed a small performance bug with `format_version=7` when decompressing formats other than Snappy and ZSTD.
-* Fixed an infinite compaction loop bug with User-Defined Timestamps (UDT) where bottommost files were repeatedly marked for compaction even though their timestamp could not be collapsed.
-* Bugfix for persisted UDT record sequence number zeroing logic.
-
-## 10.10.0 (12/16/2025)
-### Bug Fixes
-* Fixed a bug in best-efforts recovery that causes use-after-free crashes when accessing SST files that were cached during the recovery.
 * Fix resumable compaction incorrectly allowing resumption from a truncated range deletion that is not well handled currently.
-* Fixed a bug in `PosixRandomFileAccess` IO uring submission queue ownership & management. Fix eliminates the false positive 'Bad cqe data' IO errors in `PosixRandomFileAccess::MultiRead` when interleaved with `PosixRandomFileAccess::ReadAsync` on the same thread.

 #
-# Maintenance:
-#   1) Run `make check` so LOG is up-to-date.
-#   2) Run `make suggest-slow-tests` to see candidate slow binaries.
-#   3) Add binaries with high per-shard time (slow critical path) or high
-#      total time across many shards (need early queueing for fan-out).
-# Each alternative is wrapped in `^.*NAME.*$$` so the *whole input line* is
-# captured into $$1; then `s,(...),100 $$1,` prepends "100 " to the line.

-# Tiers below are based on observed timings (see suggest-slow-tests).
-# Tier 1: max single-shard time >= 30s (critical-path bottlenecks).
-# Tier 2: max single-shard time 15-30s.
-# Tier 3: huge total time across many tiny shards; front-loading them keeps
-#         the tail of the run busy while big shards finish.

-## Pattern 1: Adding a Standard Column Family Option
-
-Example reference: commit `94e65a2e0b4f817aa4bfa4c96cdf867e7980d7bc` (memtable_verify_per_key_checksum_on_seek)
-
-### Step 1: Define the Option in Public Header
-
-**File: `include/rocksdb/advanced_options.h`**
-
-Add the option with documentation in `AdvancedColumnFamilyOptions` struct:
-
-```cpp
-// Enables additional integrity checks during seek.
-// Specifically, for skiplist-based memtables, key checksum validation could
-// be enabled during seek optionally. This is helpful to detect corrupted
-// memtable keys during reads. Enabling this feature incurs a performance
-// overhead due to additional key checksum validation during memtable seek
-// operation.
-// This option depends on memtable_protection_bytes_per_key to be non zero.
-// If memtable_protection_bytes_per_key is zero, no validation is performed.
-bool memtable_verify_per_key_checksum_on_seek = false;
-```
-
-### Step 2: Add to Internal Options Structs
-
-**File: `options/cf_options.h`**
-
-Add to `MutableCFOptions` struct (or `ImmutableCFOptions` for immutable options):
-
-```cpp
-// In MutableCFOptions constructor from Options:
-memtable_verify_per_key_checksum_on_seek(
-    options.memtable_verify_per_key_checksum_on_seek),
-
-// In MutableCFOptions default constructor:
-memtable_verify_per_key_checksum_on_seek(false),
-
-// In MutableCFOptions struct member declarations:
-bool memtable_verify_per_key_checksum_on_seek;
-```
-
-### Step 3: Register for Serialization/Deserialization
-
-**File: `options/cf_options.cc`**
-
-Add to the options type info map for serialization:
-
-```cpp
-{"memtable_verify_per_key_checksum_on_seek",
- {offsetof(struct MutableCFOptions,
-           memtable_verify_per_key_checksum_on_seek),
-  OptionType::kBoolean, OptionVerificationType::kNormal,
-  OptionTypeFlags::kMutable}},
-```
-
-Add logging in `MutableCFOptions::Dump()`:
-
-```cpp
-ROCKS_LOG_INFO(log, "memtable_verify_per_key_checksum_on_seek: %d",
-               memtable_verify_per_key_checksum_on_seek);
-```
-
-### Step 4: Update Options Helper
-
-**File: `options/options_helper.cc`**
-
-Add to `UpdateColumnFamilyOptions()`:
-
-```cpp
-cf_opts->memtable_verify_per_key_checksum_on_seek =
-    moptions.memtable_verify_per_key_checksum_on_seek;
-```
-
-### Step 5: Add to Options Settable Test
-
-**File: `options/options_settable_test.cc`**
-
-Add to the test string in `ColumnFamilyOptionsAllFieldsSettable`:
-
-```cpp
-"memtable_verify_per_key_checksum_on_seek=1;"
-```
-
-### Step 6: Add db_stress Support
-
-**File: `db_stress_tool/db_stress_common.h`**
-
-```cpp
-DECLARE_bool(memtable_verify_per_key_checksum_on_seek);
-```
-
-**File: `db_stress_tool/db_stress_gflags.cc`**
-
-```cpp
-DEFINE_bool(
-    memtable_verify_per_key_checksum_on_seek,
-    ROCKSDB_NAMESPACE::Options().memtable_verify_per_key_checksum_on_seek,
-    "Sets CF option memtable_verify_per_key_checksum_on_seek.");
-```
-
-**File: `db_stress_tool/db_stress_test_base.cc`**
-
-```cpp
-options.memtable_verify_per_key_checksum_on_seek =
-    FLAGS_memtable_verify_per_key_checksum_on_seek;
-```
-
-### Step 7: Add db_bench Support
-
-**File: `tools/db_bench_tool.cc`**
-
-```cpp
-// Flag definition (near related flags):
-DEFINE_bool(memtable_verify_per_key_checksum_on_seek, false,
-            "Sets CF option memtable_verify_per_key_checksum_on_seek");
-
-// Apply flag to options (in InitializeOptionsFromFlags or similar):
-options.memtable_verify_per_key_checksum_on_seek =
-    FLAGS_memtable_verify_per_key_checksum_on_seek;
-```
-
-### Step 8: Add Crash Test Support
-
-**File: `tools/db_crashtest.py`**
-
-```python
-"memtable_verify_per_key_checksum_on_seek": lambda: random.choice([0] * 7 + [1]),
-```
-
-Also add constraint handling in `finalize_and_sanitize()` if needed:
-
-```python
-# only skip list memtable representation supports paranoid memory checks
-if dest_params.get("memtablerep") != "skip_list":
-    dest_params["memtable_verify_per_key_checksum_on_seek"] = 0
-```
-
-### Step 9: Add Release Note
-
-**File: `unreleased_history/new_features/<descriptive_name>.md`**
-
-```markdown
-A new flag memtable_verify_per_key_checksum_on_seek is added to AdvancedColumnFamilyOptions. When it is enabled, it will validate key checksum along the binary search path on skiplist based memtable during seek operation.
-```

-
-## Pattern 2: Adding a BlockBasedTableOptions Option
-
-Example reference: commit `742741b175c5f238374c1714f9db3340d49de569` (super_block_alignment_size)
-
-### Step 1: Define the Option in Public Header
-
-**File: `include/rocksdb/table.h`**
-
-Add to `BlockBasedTableOptions` struct with documentation:
-
-```cpp
-// Align data blocks on super block alignment. Avoid a data block split across
-// super block boundaries. Works with/without compression.
-//
-// Here a "super block" refers to an aligned unit of underlying Filesystem
-// storage for which there is an extra cost when a random read involves two
-// such super blocks instead of just one. Configuring that size here suggests
-// inserting padding in the SST file to avoid a single SST block splitting
-// across two super blocks. Only power-of-two sizes are supported. See also
-// super_block_alignment_space_overhead_ratio. Default to 0, which means super
-// block alignment is disabled.
-size_t super_block_alignment_size = 0;
-
-// This option controls the storage space overhead of super block alignment.
-// It is used to calculate the max padding size allowed for super block
-// alignment. It is calculated in this way. If super_block_alignment_size is
-// 2MB, and super_block_alignment_overhead_ratio is 128, then the max padding
-// size allowed for super block alignment is 2MB / 128 = 16KB.
-// Note that, when it is set to 0, super block alignment is disabled.
-size_t super_block_alignment_space_overhead_ratio = 128;
-```
-
-### Step 2: Register for Serialization in Table Factory
-
-**File: `table/block_based/block_based_table_factory.cc`**
-
-Add to the type info map:
-
-```cpp
-{"super_block_alignment_size",
- {offsetof(struct BlockBasedTableOptions, super_block_alignment_size),
-  OptionType::kSizeT, OptionVerificationType::kNormal}},
-{"super_block_alignment_space_overhead_ratio",
- {offsetof(struct BlockBasedTableOptions,
-           super_block_alignment_space_overhead_ratio),
-  OptionType::kSizeT, OptionVerificationType::kNormal}},
-```
-
-Add validation in `ValidateOptions()`:
-
-```cpp
-if ((table_options_.super_block_alignment_size &
-     (table_options_.super_block_alignment_size - 1))) {
-  return Status::InvalidArgument(
-      "Super Block alignment requested but super block alignment size is not "
-      "a power of 2");
-}
-if (table_options_.super_block_alignment_size >
-    std::numeric_limits<uint32_t>::max()) {
-  return Status::InvalidArgument(
-      "Super block alignment size exceeds maximum number (4GiB) allowed");
-}
-```
-
-Add printing in `GetPrintableOptions()`:
-
-```cpp
-snprintf(buffer, kBufferSize,
-         "  super_block_alignment_size: %" ROCKSDB_PRIszt "\n",
-         table_options_.super_block_alignment_size);
-ret.append(buffer);
-```
-
-### Step 3: Add to Options Settable Test
-
-**File: `options/options_settable_test.cc`**
-
-Add to `BlockBasedTableOptionsAllFieldsSettable` test:
-
-```cpp
-"super_block_alignment_size=65536;"
-"super_block_alignment_space_overhead_ratio=4096;"
-```
-
-### Step 4: Add to Options Test
-
-**File: `options/options_test.cc`**
-
-```cpp
-ASSERT_OK(GetColumnFamilyOptionsFromString(
-    config_options, cf_opts,
-    "block_based_table_factory.super_block_alignment_size=65536; "
-    "block_based_table_factory.super_block_alignment_space_overhead_ratio=4096;",
-    &cf_opts));
-ASSERT_EQ(bbto->super_block_alignment_size, 65536);
-ASSERT_EQ(bbto->super_block_alignment_space_overhead_ratio, 4096);
-```
-
-### Step 5: Add db_stress Support
-
-**File: `db_stress_tool/db_stress_common.h`**
-
-```cpp
-DECLARE_uint64(super_block_alignment_size);
-DECLARE_uint64(super_block_alignment_space_overhead_ratio);
-```
-
-**File: `db_stress_tool/db_stress_gflags.cc`**
-
-```cpp
-DEFINE_uint64(
-    super_block_alignment_size,
-    ROCKSDB_NAMESPACE::BlockBasedTableOptions().super_block_alignment_size,
-    "BlockBasedTableOptions.super_block_alignment_size");
-
-DEFINE_uint64(
-    super_block_alignment_space_overhead_ratio,
-    ROCKSDB_NAMESPACE::BlockBasedTableOptions()
-        .super_block_alignment_space_overhead_ratio,
-    "BlockBasedTableOptions.super_block_alignment_space_overhead_ratio");
-```
-
-**File: `db_stress_tool/db_stress_test_base.cc`**
-
-```cpp
-block_based_options.super_block_alignment_size =
-    fLU64::FLAGS_super_block_alignment_size;
-block_based_options.super_block_alignment_space_overhead_ratio =
-    fLU64::FLAGS_super_block_alignment_space_overhead_ratio;
-```
-
-### Step 6: Add db_bench Support
-
-**File: `tools/db_bench_tool.cc`**
-
-```cpp
-// Flag definitions:
-DEFINE_uint64(
-    super_block_alignment_size,
-    ROCKSDB_NAMESPACE::BlockBasedTableOptions().super_block_alignment_size,
-    "Configure super block size");
-
-DEFINE_uint64(super_block_alignment_space_overhead_ratio,
-              ROCKSDB_NAMESPACE::BlockBasedTableOptions()
-                  .super_block_alignment_space_overhead_ratio,
-              "Configure space overhead for super block alignment");
-
-// Apply to block_based_options (in the block where other options are set):
-block_based_options.super_block_alignment_size = FLAGS_super_block_alignment_size;
-block_based_options.super_block_alignment_space_overhead_ratio =
-    FLAGS_super_block_alignment_space_overhead_ratio;
-```
-
-### Step 7: Add Crash Test Support
-
-**File: `tools/db_crashtest.py`**
-
-```python
-"super_block_alignment_size": lambda: random.choice(
-    [0, 128 * 1024, 512 * 1024, 2 * 1024 * 1024]
-),
-"super_block_alignment_space_overhead_ratio": lambda: random.choice([0, 32, 4096]),
-```
-
-### Step 8: Add Java API Support
-
-**File: `java/src/main/java/org/rocksdb/BlockBasedTableConfig.java`**
-
-Add getter and setter methods:
-
-```java
-/**
- * Get the super block alignment size.
- *
- * @return the super block alignment size.
- */
-public long superBlockAlignmentSize() {
-  return superBlockAlignmentSize;
-}
-
-/**
- * Set the super block alignment size.
- * When set to 0, super block alignment is disabled.
- *
- * @param superBlockAlignmentSize the super block alignment size.
- *
- * @return the reference to the current option.
- */
-public BlockBasedTableConfig setSuperBlockAlignmentSize(final long superBlockAlignmentSize) {
-  this.superBlockAlignmentSize = superBlockAlignmentSize;
-  return this;
-}
-```
-
-Add member variable:
-
-```java
-private long superBlockAlignmentSize;
-```
-
-Update constructor and native method signature.
-
-**File: `java/rocksjni/portal.h`**
-
-Update `GetMethodID` signature and add fields to Java object construction.
-
-**File: `java/rocksjni/table.cc`**
-
-Add parameters to JNI function and apply to options.
-
-**File: `java/src/test/java/org/rocksdb/BlockBasedTableConfigTest.java`**
-
-Add unit tests:
-
-```java
-@Test
-public void superBlockAlignmentSize() {
-  final BlockBasedTableConfig blockBasedTableConfig = new BlockBasedTableConfig();
-  blockBasedTableConfig.setSuperBlockAlignmentSize(1024 * 1024);
-  assertThat(blockBasedTableConfig.superBlockAlignmentSize()).isEqualTo(1024 * 1024);
-}
-```

-
-## Pattern 3: Adding C API for Existing Option
-
-Example reference: commit `429b36c22d76403d275dd0e6877b08d4cea2bc90` (block_align C API)
-
-If an option already exists but needs C API support:
-
-**First decide whether the option is auto-managed.**
-
-Many simple option fields are no longer maintained by hand in
-`include/rocksdb/c.h` and `db/c.cc`. Before adding a manual wrapper:
-
-- Check whether the option belongs to a family handled by
-  `tools/c_api_gen/auto_simple_bindings.py`.
-- If it is a simple scalar/enum/string field in an auto-managed family, run
-  `python3 tools/c_api_gen/regen_all.py` and let the generator add the C API.
-- After regenerating, run
-  `python3 tools/c_api_gen/verify_generated_up_to_date.py` to confirm the
-  checked-in generated fragments stay stable.
-- Do not edit generated `.inc` files under `c_api_gen/` by hand.
-- If the new field is not ready for C API support yet, add an entry to
-  `tools/c_api_gen/auto_simple_bindings_blocklist.json` with
-  `"policy": "deferred"` and a concrete reason so the build stays intentional
-  rather than silently drifting.
-- If the field needs custom ownership, callback, vector, or nested-struct
-  marshalling, keep it manual or move it into `tools/c_api_gen/spec.json`
-  depending on the API shape.
-
-If the option is not auto-managed, or the C API really is a custom/manual case,
-the traditional hand-written pattern still applies:
-
-**File: `db/c.cc`**
-
-```cpp
-void rocksdb_block_based_options_set_block_align(
-    rocksdb_block_based_table_options_t* options, unsigned char v) {
-  options->rep.block_align = v;
-}
-```
-
-**File: `include/rocksdb/c.h`**
-
-```cpp
-extern ROCKSDB_LIBRARY_API void rocksdb_block_based_options_set_block_align(
-    rocksdb_block_based_table_options_t*, unsigned char);
-```
-
----
-
-## Unit Testing Guidelines
-
-### For Standard Options
-
-Add tests in appropriate test files (e.g., `db/db_memtable_test.cc`, `db/db_options_test.cc`):
-
-```cpp
-TEST_F(DBMemTableTest, YourOptionTest) {
-  Options options;
-  options.your_new_option = true;
-  Reopen(options);
-  // Test the behavior
-}
-```
-
-### For BlockBasedTableOptions
-
-Add tests in `db/db_flush_test.cc`, `table/block_based/block_based_table_reader_test.cc`, or `table/table_test.cc`:
-
-```cpp
-TEST_P(DBFlushYourFeatureTest, YourFeature) {
-  Options options;
-  BlockBasedTableOptions block_options;
-  block_options.your_new_option = some_value;
-  options.table_factory.reset(NewBlockBasedTableFactory(block_options));
-
-  ASSERT_OK(options.table_factory->ValidateOptions(
-      DBOptions(options), ColumnFamilyOptions(options)));
-
-  Reopen(options);
-  // Test the behavior
-}
-```

-# RocksDB API Development Guide
-
-This document provides guidance for adding new public APIs to RocksDB, following the established patterns used by existing APIs like `CompactRange`.
-
-## API Layer Architecture
-
-RocksDB exposes public APIs through multiple layers. Users can access RocksDB through any of the three public APIs: C++ headers, C headers, or Java bindings.
-
-Here is an example for public header db.h:
-
-```
-┌─────────────────────────────────────────────────────────────────────────────┐
-│                     Level 1: Public APIs (User Entry Points)                │
-├───────────────────────┬─────────────────────────┬───────────────────────────┤
-│   C++ Public API      │     C API Bindings      │       Java/JNI API        │
-│ include/rocksdb/db.h  │   include/rocksdb/c.h   │ java/src/.../RocksDB.java │
-│ include/rocksdb/*.h   │                         │ java/src/.../*.java       │

-
-## Step-by-Step Guide: Adding a New Public API
-
-### Step 1: Define the C++ Public Interface
-
-**File:** `include/rocksdb/db.h`
-
-Add the virtual method declaration in the `DB` class:
-
-\`\`\`cpp
-// Pure virtual - must be implemented by DBImpl
-virtual Status YourNewAPI(const YourAPIOptions& options,
-                          ColumnFamilyHandle* column_family,
-                          /* other params */) = 0;
-
-// Convenience overload for default column family
-virtual Status YourNewAPI(const YourAPIOptions& options,
-                          /* other params */) {
-  return YourNewAPI(options, DefaultColumnFamily(), /* other params */);
-}
-\`\`\`
-
-**Key Patterns:**
-- Use `Status` return type for error handling
-- Use `OptSlice` to avoid unnecessary levels of indirection and use of raw pointers.
-- Use `ColumnFamilyHandle*` for column family support
-- Provide convenience overloads for the default column family
-
-### Step 2: Define Options Struct (If Needed)
-
-**File:** `include/rocksdb/options.h`
-
-If your API has multiple configuration options, define an options struct:
-
-\`\`\`cpp
-struct YourAPIOptions {
-  // Document each option with clear comments
-  bool some_boolean_option = false;
-
-  // Default value explanation
-  int some_int_option = -1;
-
-  // Pointer options require careful lifetime management
-  std::atomic<bool>* canceled = nullptr;
-
-  // Enum options for multi-choice settings
-  YourEnumType some_enum = YourEnumType::kDefault;
-};
-\`\`\`
-
-**Key Patterns:**
-- Use sensible default values specified inline (e.g., `= false`, `= -1`)
-- Do NOT redundantly document the default value in comments; instead, document the rationale (why this default), historical context, and how different values are interpreted
-- Group related options logically
-- Consider thread-safety for pointer options
-
-### Step 3: Implement in DBImpl
-
-**Header:** `db/db_impl/db_impl.h`
-
-\`\`\`cpp
-using DB::YourNewAPI;
-Status YourNewAPI(const YourAPIOptions& options,
-                  ColumnFamilyHandle* column_family,
-                  /* other params */) override;
-
-// Private internal implementation if needed
-Status YourNewAPIInternal(const YourAPIOptions& options,
-                          ColumnFamilyHandle* column_family,
-                          /* other params */);
-\`\`\`
-
-**Implementation:** `db/db_impl/db_impl_<category>.cc`
-
-Choose the appropriate implementation file based on functionality:
-- `db_impl_compaction_flush.cc` - Compaction and flush operations
-- `db_impl_write.cc` - Write operations
-- `db_impl_open.cc` - DB opening/closing
-- `db_impl_files.cc` - File operations
-- `db_impl.cc` - General operations
-
-\`\`\`cpp
-Status DBImpl::YourNewAPI(const YourAPIOptions& options,
-                          ColumnFamilyHandle* column_family,
-                          /* other params */) {
-  // 1. Input validation
-  if (/* invalid input */) {
-    return Status::InvalidArgument("Error message");
-  }
-
-  // 2. Check for cancellation/abort conditions
-  if (options.canceled && options.canceled->load(std::memory_order_acquire)) {
-    return Status::Incomplete(Status::SubCode::kManualCompactionPaused);
-  }
-
-  // 3. Get column family data
-  auto cfh = static_cast<ColumnFamilyHandleImpl*>(column_family);
-  auto cfd = cfh->cfd();
-
-  // 4. Core implementation logic
-  // ...
-
-  return Status::OK();
-}
-\`\`\`
-
-### Step 4: Handle Special DB Types
-
-**StackableDB (Wrapper DBs):**
-**File:** `include/rocksdb/utilities/stackable_db.h`
-
-\`\`\`cpp
-using DB::YourNewAPI;
-Status YourNewAPI(const YourAPIOptions& options,
-                  ColumnFamilyHandle* column_family,
-                  /* other params */) override {
-  return db_->YourNewAPI(options, column_family, /* other params */);
-}
-\`\`\`
-
-**Secondary DB (Read-Only):**
-**File:** `db/db_impl/db_impl_secondary.h`
-
-\`\`\`cpp
-using DBImpl::YourNewAPI;
-Status YourNewAPI(const YourAPIOptions& /*options*/,
-                  ColumnFamilyHandle* /*column_family*/,
-                  /* other params */) override {
-  return Status::NotSupported("Not supported in secondary DB");
-}
-\`\`\`
-
-**CompactedDB (Read-Only):**
-**File:** `db/db_impl/compacted_db_impl.h`
-
-\`\`\`cpp
-using DBImpl::YourNewAPI;
-Status YourNewAPI(const YourAPIOptions& /*options*/,
-                  ColumnFamilyHandle* /*column_family*/,
-                  /* other params */) override {
-  return Status::NotSupported("Not supported for read-only DB");
-}
-\`\`\`
-
-### Step 5: Add C API Bindings
-
-> **Important:** `include/rocksdb/c.h` and `db/c.cc` are `@generated` and must
-> NOT be edited by hand — your changes would be overwritten on the next
-> regeneration. Choose the right path first (see "Before writing C API code by
-> hand" below). For hand-written (manual) wrappers, edit the source templates
-> `tools/c_api_gen/c_base.h` (declarations) and `tools/c_api_gen/c_base.cc`
-> (implementations), then run `python3 tools/c_api_gen/regen_all.py` to produce
-> `c.h` / `c.cc`. The snippets below show the *declaration* and *implementation*
-> you would add to those templates.
-
-**Header (declaration → `tools/c_api_gen/c_base.h`):**
-
-```c
-// Basic version
-extern ROCKSDB_LIBRARY_API void rocksdb_your_new_api(
-    rocksdb_t* db,
-    const char* start_key, size_t start_key_len,
-    const char* limit_key, size_t limit_key_len);
-
-// Column family version
-extern ROCKSDB_LIBRARY_API void rocksdb_your_new_api_cf(
-    rocksdb_t* db, rocksdb_column_family_handle_t* column_family,
-    const char* start_key, size_t start_key_len,
-    const char* limit_key, size_t limit_key_len);
-
-// With options and error handling
-extern ROCKSDB_LIBRARY_API void rocksdb_your_new_api_opt(
-    rocksdb_t* db, rocksdb_your_api_options_t* opt,
-    const char* start_key, size_t start_key_len,
-    const char* limit_key, size_t limit_key_len,
-    char** errptr);
-\`\`\`
-
-**Implementation (→ `tools/c_api_gen/c_base.cc`):**
-
-\`\`\`cpp
-void rocksdb_your_new_api(rocksdb_t* db, const char* start_key,
-                          size_t start_key_len, const char* limit_key,
-                          size_t limit_key_len) {
-  Slice a, b;
-  db->rep->YourNewAPI(
-      YourAPIOptions(),  // Default options
-      (start_key ? (a = Slice(start_key, start_key_len), &a) : nullptr),
-      (limit_key ? (b = Slice(limit_key, limit_key_len), &b) : nullptr));
-}
-
-void rocksdb_your_new_api_cf(rocksdb_t* db,
-                             rocksdb_column_family_handle_t* column_family,
-                             const char* start_key, size_t start_key_len,
-                             const char* limit_key, size_t limit_key_len) {
-  Slice a, b;
-  db->rep->YourNewAPI(
-      YourAPIOptions(),
-      column_family->rep,
-      (start_key ? (a = Slice(start_key, start_key_len), &a) : nullptr),
-      (limit_key ? (b = Slice(limit_key, limit_key_len), &b) : nullptr));
-}
-\`\`\`
-
-**Before writing C API code by hand, choose the right path:**
-
-- **Auto-managed simple struct fields:** If you added a new field to a managed
-  public struct such as `ReadOptions`, selected option structs, or managed
-  metadata structs, first check `tools/c_api_gen/auto_simple_bindings.py`.
-  Simple scalar/enum/string fields should be regenerated with
-  `python3 tools/c_api_gen/regen_all.py` rather than hand-editing
-  `include/rocksdb/c.h` / `db/c.cc`.
-  After regenerating, run
-  `python3 tools/c_api_gen/verify_generated_up_to_date.py` to confirm the
-  checked-in generated fragments are stable.
-- **Spec-driven wrappers:** If the API is still mechanically generated but needs
-  an explicit C shape, naming, or `Status`/`char** errptr` policy, add it to
-  `tools/c_api_gen/spec.json`.
-- **Fully manual wrappers:** If the API uses callbacks, ownership transfer,
-  vectors/maps, open flows, or otherwise irregular marshalling, keep the C API
-  hand-written.
-
-**Temporary deferral for auto-managed families:**
-
-If a new field lands in an auto-managed family but the C API shape is not ready
-yet, add a checked-in entry to
-`tools/c_api_gen/auto_simple_bindings_blocklist.json` with:
-
-- `policy: "manual"` when the field is intentionally outside simple auto-gen
-- `policy: "deferred"` when the field should be revisited later
-- a concrete `reason`
-- `tracking_issue` when available
-
-If a field in an auto-managed family is not supported by the generator and is
-not covered by the blocklist, regeneration should fail. That is intentional.
-
-**If you have options, also add:**
-
-\`\`\`cpp
-// Options struct wrapper
-struct rocksdb_your_api_options_t {
-  YourAPIOptions rep;
-};
-
-rocksdb_your_api_options_t* rocksdb_your_api_options_create() {
-  return new rocksdb_your_api_options_t;
-}
-
-void rocksdb_your_api_options_destroy(rocksdb_your_api_options_t* opt) {
-  delete opt;
-}
-
-void rocksdb_your_api_options_set_some_option(
-    rocksdb_your_api_options_t* opt, unsigned char value) {
-  opt->rep.some_boolean_option = value;
-}
-\`\`\`
-
-### Step 6: Add Java Bindings
-
-**Java API:** `java/src/main/java/org/rocksdb/RocksDB.java`
-
-\`\`\`java
-// Basic version
-public void yourNewAPI() throws RocksDBException {
-  yourNewAPI(null);
-}
-
-// Column family version
-public void yourNewAPI(ColumnFamilyHandle columnFamilyHandle)
-    throws RocksDBException {
-  yourNewAPI(nativeHandle_, null, -1, null, -1, 0,
-      columnFamilyHandle == null ? 0 : columnFamilyHandle.nativeHandle_);
-}
-
-// Range version
-public void yourNewAPI(final byte[] begin, final byte[] end)
-    throws RocksDBException {
-  yourNewAPI(null, begin, end);
-}
-
-// Full-featured version with options
-public void yourNewAPI(ColumnFamilyHandle columnFamilyHandle,
-                       final byte[] begin, final byte[] end,
-                       final YourAPIOptions options)
-    throws RocksDBException {
-  yourNewAPI(nativeHandle_,
-      begin, begin == null ? -1 : begin.length,
-      end, end == null ? -1 : end.length,
-      options.nativeHandle_,
-      columnFamilyHandle == null ? 0 : columnFamilyHandle.nativeHandle_);
-}
-
-// Native method declaration
-private static native void yourNewAPI(final long handle,
-    /* @Nullable */ final byte[] begin, final int beginLen,
-    /* @Nullable */ final byte[] end, final int endLen,
-    final long optionsHandle,
-    final long cfHandle);
-\`\`\`
-
-**Options Class:** `java/src/main/java/org/rocksdb/YourAPIOptions.java`
-
-\`\`\`java
-public class YourAPIOptions extends RocksObject {
-
-  public YourAPIOptions() {
-    super(newYourAPIOptions());
-  }
-
-  // Builder pattern setters
-  public YourAPIOptions setSomeBooleanOption(boolean value) {
-    setSomeBooleanOption(nativeHandle_, value);
-    return this;
-  }
-
-  // Getters
-  public boolean someBooleanOption() {
-    return someBooleanOption(nativeHandle_);
-  }
-
-  // Native method declarations
-  private static native long newYourAPIOptions();
-  private static native void disposeInternalJni(long handle);
-  private static native void setSomeBooleanOption(long handle, boolean value);
-  private static native boolean someBooleanOption(long handle);
-
-  @Override
-  protected final void disposeInternal(final long handle) {
-    disposeInternalJni(handle);
-  }
-}
-\`\`\`
-
-**JNI Implementation:** `java/rocksjni/rocksjni.cc`
-
-\`\`\`cpp
-void Java_org_rocksdb_RocksDB_yourNewAPI(
-    JNIEnv* env, jclass,
-    jlong jdb_handle, jbyteArray jbegin, jint jbegin_len,

-        &has_exception);
-    if (has_exception == JNI_TRUE) return;
-  }
-
-  std::string str_end;
-  if (jend_len > 0) {
-    str_end = ROCKSDB_NAMESPACE::JniUtil::byteString<std::string>(
-        env, jend, jend_len,
-        [](const char* str, const size_t len) { return std::string(str, len); },
-        &has_exception);
-    if (has_exception == JNI_TRUE) return;
-  }
-
-  // 2. Get or create options
-  ROCKSDB_NAMESPACE::YourAPIOptions* options = nullptr;
-  if (joptions_handle == 0) {
-    options = new ROCKSDB_NAMESPACE::YourAPIOptions();
-  } else {
-    options = reinterpret_cast<ROCKSDB_NAMESPACE::YourAPIOptions*>(joptions_handle);
-  }
-
-  // 3. Unwrap handles
-  auto* db = reinterpret_cast<ROCKSDB_NAMESPACE::DB*>(jdb_handle);
-  ROCKSDB_NAMESPACE::ColumnFamilyHandle* cf_handle =
-      jcf_handle == 0 ? db->DefaultColumnFamily()

-  if (jbegin_len > 0) begin.reset(new ROCKSDB_NAMESPACE::Slice(str_begin));
-  if (jend_len > 0) end.reset(new ROCKSDB_NAMESPACE::Slice(str_end));
-
-  // 5. Call C++ API
-  ROCKSDB_NAMESPACE::Status s = db->YourNewAPI(*options, cf_handle, begin.get(), end.get());
-
-  // 6. Cleanup if we created options
-  if (joptions_handle == 0) delete options;
-
-  // 7. Throw Java exception on error
-  ROCKSDB_NAMESPACE::RocksDBExceptionJni::ThrowNew(env, s);
-}
-\`\`\`
-
-**Options JNI:** `java/rocksjni/your_api_options.cc`
-
-\`\`\`cpp
-jlong Java_org_rocksdb_YourAPIOptions_newYourAPIOptions(JNIEnv*, jclass) {
-  auto* options = new ROCKSDB_NAMESPACE::YourAPIOptions();
-  return GET_CPLUSPLUS_POINTER(options);
-}
-
-void Java_org_rocksdb_YourAPIOptions_disposeInternalJni(JNIEnv*, jclass, jlong jhandle) {

-
-void Java_org_rocksdb_YourAPIOptions_setSomeBooleanOption(

-  auto* options = reinterpret_cast<ROCKSDB_NAMESPACE::YourAPIOptions*>(jhandle);
-  return static_cast<jboolean>(options->some_boolean_option);
-}
-\`\`\`
-
-### Step 7: Update Build Files
-
-**Java CMakeLists.txt:** `java/CMakeLists.txt`
-
-Add your new Java source files:
-\`\`\`cmake
-src/main/java/org/rocksdb/YourAPIOptions.java
-src/test/java/org/rocksdb/YourAPIOptionsTest.java
-\`\`\`
-
-### Step 8: Add Release Notes
-
-**Directory:** `unreleased_history/`
-
-RocksDB uses individual files in the `unreleased_history/` directory rather than directly editing `HISTORY.md`. This avoids merge conflicts and ensures changes are attributed to the correct release version.
-
-Add a file to the appropriate subdirectory:
-- `unreleased_history/new_features/` - For new functionality
-- `unreleased_history/public_api_changes/` - For API changes
-- `unreleased_history/behavior_changes/` - For behavior modifications
-- `unreleased_history/bug_fixes/` - For bug fixes
-
-**Example:** `unreleased_history/new_features/your_new_api.md`
-
-\`\`\`markdown
-Added `YourNewAPI()` to support [describe functionality]. See `YourAPIOptions` for configuration.
-\`\`\`
-
-**Example:** `unreleased_history/public_api_changes/your_api_options.md`
-
-**Note:** Files should contain one line of markdown. The "* " prefix is automatically added if not included. These files are compiled into `HISTORY.md` during the release process.
-
-### Step 9: Add Tests
-
-**C++ Unit Tests:** `db/db_your_api_test.cc` or add to existing test file
-
-\`\`\`cpp
-TEST_F(DBTest, YourNewAPIBasic) {
-  Options options = CurrentOptions();
-  CreateAndReopenWithCF({"pikachu"}, options);
-
-  // Setup test data
-  ASSERT_OK(Put(1, "key1", "value1"));
-  ASSERT_OK(Put(1, "key2", "value2"));
-
-  // Test your API
-  YourAPIOptions api_options;
-  api_options.some_boolean_option = true;
-  ASSERT_OK(db_->YourNewAPI(api_options, handles_[1], nullptr, nullptr));
-
-  // Verify results
-  // ...
-}
-\`\`\`
-
-**Java Tests:** `java/src/test/java/org/rocksdb/YourAPIOptionsTest.java`
-
-\`\`\`java
-public class YourAPIOptionsTest {
-  @Test
-  public void yourAPIOptions() {
-    try (final YourAPIOptions options = new YourAPIOptions()) {
-      assertFalse(options.someBooleanOption());
-      options.setSomeBooleanOption(true);
-      assertTrue(options.someBooleanOption());
-    }
-  }
-}

-## Best Practices
-
-1. **Error Handling**: Always return `Status` objects in C++, throw exceptions in Java
-2. **Default Values**: Provide sensible defaults for all options
-3. **Documentation**: Add clear comments for all public methods and options
-4. **Column Family Support**: Always support column family operations
-5. **Thread Safety**: Document thread-safety guarantees
-6. **Backward Compatibility**: Avoid breaking existing API contracts
-7. **Testing**: Add comprehensive unit tests for all code paths

-# PR Complexity Classifier — CI Triage Prompt
-
-## Purpose
-Quickly classify a RocksDB pull request as **simple** or **complex** so the
-downstream reviewer can pick an appropriate thinking budget.
-
-## Output Contract (STRICT)
-Your final response MUST be exactly one of these two lowercase tokens, on a
-line by itself, with no other text:
-
-```
-simple
-```
-
-or
-
-```
-complex
-```
-
-If you are unsure, output `complex`. The downstream review will use this token
-to set its thinking budget — when in doubt, prefer the more thorough budget.
-
-## Classification Heuristics
-
-Treat a PR as **simple** when ALL of the following hold:
-- Diff touches < ~200 lines of non-test code
-- No changes to public headers under `include/rocksdb/`
-- No changes to on-disk format (SST block layout, WAL record layout,
-  manifest, options file format, version edit encoding)
-- No changes to compaction picker, write-path locking, recovery, or
-  WAL/memtable lifecycle
-- No new public option, no new statistics counter, no new RPC/serialized
-  message
-- Tests-only or docs-only changes
-- Trivial refactors (rename, comment, dead-code removal, lint fixes)
-- One-line bug fix with obvious root cause and a focused regression test
-
-Treat a PR as **complex** when ANY of the following hold:
-- Touches files in `db/`, `db/compaction/`, `db/blob/`, `cache/`,
-  `table/block_based/`, `file/`, `env/io_*` with > ~50 lines of logic change
-- Modifies thread-safety/synchronization (mutexes, atomics, memory ordering,
-  refcounting, condvars)
-- Changes serialization or on-disk format
-- Changes public API surface in `include/rocksdb/`
-- Adds a new feature flag, option, or compaction style
-- Touches transactions (`utilities/transactions/`), backup/checkpoint,
-  user-defined timestamps, or remote compaction
-- Cross-cutting refactor spanning > 5 directories
-
-## How To Decide
-1. Read the diff summary and changed-file list provided below.
-2. Skim the diff hunks — focus on which subsystems are touched and whether
-   the change is mechanical vs. semantic.
-3. Apply the heuristics above. Default to `complex` if the rules conflict.
-4. Output the single token. No preamble. No explanation.
-
-## Tool Use
-You may use `View`, `GlobTool`, and `GrepTool` to peek at one or two files
-if the diff snippet alone is ambiguous, but keep this fast — this is a
-triage step, not a review. Do NOT spawn sub-agents.

-# Code Review Workflow — CI Prompt
-
-## Purpose
-Thorough multi-agent code review for RocksDB commits following CLAUDE.md guidelines,
-with structured codebase exploration, inter-agent debate, and verification.
-
-IMPORTANT — Where the review goes: Your FINAL RESPONSE TEXT is the review.
-The PR comment is generated verbatim from your final response, so the
-complete, polished review MUST appear there in full. Do NOT end your turn with
-a meta-summary such as "the review has been written to review-findings.md" —
-paste the entire review as your response.
-
-review-findings.md is a RECOVERY BACKSTOP, not the primary output: after
-completing EACH major phase (Setup, Codebase Context, Initial Review, Debate,
-Synthesis), append your current findings to it with the Write tool, and after
-the final synthesis overwrite it with the complete review. This preserves
-partial results if the turn limit interrupts the run (a recovery step reads
-this file); it does NOT substitute for outputting the full review as your
-final response.
-
-## Workflow Steps
-
-### 1. Setup Phase
-- Read CLAUDE.md to understand review guidelines
-- Identify the commit/diff/PR to review
-- The PR diff is provided below in this prompt. The repository is already
-  checked out — use local file search tools (Grep, Glob, Read) to explore.
-- Parse the changed files and categorize them (API, core logic, tests, etc.)
-- Read all changed files to build full context
-
-### 2. Codebase Context Phase (CRITICAL — Do Not Skip)
-
-**Why this matters**: Review agents that only see the diff miss systemic bugs.
-For example, a change to an iterator's return value might look correct in
-isolation but break multi-SST iteration 5 layers up the call stack. A change
-to error handling might silently drop errors that a caller 3 levels up relies
-on for recovery. This phase builds the context that prevents those blind spots.
-
-Go deep. Surface-level reading leads to reviews that miss caching layers,
-existing helper functions, or concurrency requirements. The most expensive
-failure mode is findings that look correct in isolation but miss how the
-change breaks the surrounding system.
-
-The team lead spawns one or more research agents to perform the following
-analyses using local file search tools (Grep, Glob, Read). The research
-must be written to `context.md` BEFORE any review agent is spawned.
-
-#### 2a. Subsystem Deep-Read
-Read the changed files AND their surrounding subsystem **in depth** — not just
-signatures, but actual logic, edge cases, data flows, locking protocols,
-concurrency patterns, and interactions between components.
-
-For each changed file, also read:
-- The header that declares its interface (if the change is in a .cc file)
-- The sibling implementation that does the same thing the "standard" way
-  (e.g., for a UDI iterator change, read how `IndexBlockIter` handles the
-  same scenario — it's the reference implementation)
-- The wrapper/adapter layer that sits between this code and its callers
-- Any existing tests to understand what behaviors are currently guaranteed
-
-#### 2b. Caller-Chain Analysis (upstream impact)
-For each changed function/method, trace the call chain UPWARD 3-5 levels to
-understand who consumes the changed behavior and what invariants they rely on.
-**Focus on control flow decisions** — if/else branches, while loop conditions,
-early returns — that depend on the changed return values or state.
-
-**How to do this**:
-- Search for callers of each changed function (search for the function name, the
-  class method, virtual overrides)
-- For each caller, search for ITS callers, repeating 3-5 levels up
-- At each level, read the actual code to understand the control flow decision
-- Stop when you reach a "terminal" caller (e.g., user-facing API, top-level
-  iterator) or when the propagation is clearly safe
-
-#### 2c. Callee-Chain Analysis (downstream dependencies AND side effects)
-For each changed function, trace what it calls and whether those calls have
-new preconditions or changed semantics. **Critically, trace SIDE EFFECTS —
-not just return values.** Many bugs hide in side effects on shared state
-(counters, sequence numbers, flags) that are invisible if you only check
-return values.
-
-**For each callee, ask:**
-1. What does it RETURN? (the obvious check)
-2. What shared state does it MUTATE? (the non-obvious check)
-3. Under what PRECONDITIONS does it operate correctly?
-4. Are those preconditions met in the new calling context?
-
-#### 2d. Sibling Implementation Comparison
-Identify the "reference" or "standard" implementation that does the same thing
-the changed code does, and compare their behavior. This is critical for plugin/
-extension APIs where the implementation must match an implicit contract.
-
-#### 2e. Invariant Documentation
-Document the key invariants that the changed code must maintain. Read existing
-comments, assertions, and test expectations to discover these invariants.
-
-#### 2f. Related Functionality and Existing Conventions
-Identify related functionality that already exists in the codebase:
-- Are there existing helper functions the change should use (or is duplicating)?
-- Are there existing patterns for the same kind of change (e.g., how other
-  Customizable subclasses handle deprecation)?
-- Are there existing tests that test similar scenarios (e.g., multi-SST
-  iteration tests that could be extended)?
-
-#### 2g. Cross-Component Data Consumer Analysis (CRITICAL — common blind spot)
-
-**Why this is separate from caller-chain analysis:** Sections 2b-2c trace
-who CALLS the changed functions. This section traces who CONSUMES the data
-that the changed code PRODUCES. These are often completely different
-subsystems.
-
-When the change writes data to a shared structure (memtable, SST block, cache
-entry, statistics counter), ask: **"Who reads this data, under what rules,
-and do those rules match the writer's assumptions?"**
-
-**How to do this:**
-1. Identify every piece of data the change WRITES (e.g., a range tombstone
-   entry, a counter update, a metadata field)
-2. For each, search the codebase for ALL readers of that data structure
-3. For each reader, check:
-   - Does the reader apply visibility rules (seqno, read_callback, snapshot)?
-   - Are those rules compatible with the writer's assumptions?
-   - Does the reader assume invariants about the data (e.g., seqno ordering,
-     monotonicity) that the writer might violate?
-
-#### 2h. Alternative Execution Contexts
-
-The same code path may run in different contexts with different assumptions.
-**Enumerate all contexts and check each one.** This is where "works in the
-common case but breaks in edge configurations" bugs hide.
-
-For RocksDB, always check whether the changed code interacts differently with:
-
-| Context | Key difference | Common failure mode |
-|---------|---------------|-------------------|
-| WritePreparedTxnDB / WriteUnpreparedTxnDB | `read_callback_` controls visibility, not just seqno | Visibility bypass |
-| ReadOnly DB / SecondaryInstance | No mutable memtable, writes not allowed | Null pointer or no-op needed |
-| CompactionService / Remote compaction | Different process, serialized state | Serialization mismatch |
-| User-defined timestamps | Extra dimension in key comparison and visibility | Wrong ordering |
-| MemPurge | Memtable-to-memtable, not memtable-to-SST | Missing data |
-| Column family with BlobDB | Values may be in blob files, not inline | Missing dereference |
-| Snapshots (old, held long-term) | Snapshot seqno may be far behind current state | Metadata corruption |
-| Concurrent writers (allow_concurrent_memtable_write) | Lock-free paths vs locked paths | Lost updates |
-| FIFO / Universal compaction | Different compaction invariants than Level | Wrong assumptions |
-| Prefix seek / total order seek | Different iterator behavior | Wrong iteration results |
-
-**For each context, ask:**
-1. Does the code execute in this context? (Check constructor, feature flags)
-2. If yes, do the assumptions still hold?
-3. If not, should the feature be disabled in this context?
-
-#### 2i. Assumption Stress-Testing (the "logically X" audit)
-
-When the change claims a property (e.g., "logically redundant," "no-op in
-this case," "safe because X"), **systematically break it:**
-
-1. **State the claim precisely.** E.g., "The inserted range tombstone is
-   logically redundant — it covers only keys already deleted by point
-   tombstones."
-2. **List the preconditions** that must be true for the claim to hold.
-3. **For each precondition, construct a counterexample** — a concrete scenario
-   where the precondition is violated.
-4. **Verify each counterexample against the code.** Does the code guard
-   against it? If not, it's a bug.
-
-**Anti-pattern: treating asserts as proofs.** When you see an assert, do NOT
-conclude "the invariant holds." Instead ask: "Can I construct an input where
-this assert fires?" If yes, it's a bug (the assert catches it in debug but
-release builds silently corrupt). If you cannot construct a counterexample
-after trying, document WHY it's impossible.
-
-#### 2j. Write Context Document
-Write the complete analysis to `context.md` in the review folder. This document
-is provided to ALL review agents as part of their prompt.
-
-**Context document template**:
-```markdown

-**Upstream callers** (who depends on this):
-1. CallerA::method() (file:line) — uses return value to decide X
-2. CallerB::method() (file:line) — passes result to CallerC
-3. CallerC::method() (file:line) — THE CRITICAL DECISION POINT: ...

-**Downstream callees** (what this depends on):

-2. calleeB() — NEW dependency, requires X
-
-**Sibling implementation** (how the "standard" version handles this):
-- StandardImpl::method() does Y at file:line, which ensures invariant Z

-## Potential Pitfalls
-- [specific scenarios where the change could interact badly with
-  the surrounding system, identified from the caller-chain analysis]
-```
-
-### 3. Initial Review Phase (Parallel)
-Create a team and spawn 5 review agents in parallel. **Include the context
-document from Phase 2 in each agent's prompt.** Each agent writes findings
-to its own file and sends a summary message to the team lead.
-
-Each agent's prompt should include:
-```
-## Codebase Context (READ THIS FIRST)
-[paste or reference the context.md file]
-
-You MUST consider how your findings interact with the upstream callers
-and system invariants documented above. A finding that looks correct
-in isolation may be a critical bug when you consider the full call chain.
-```
-
-#### Agent: Design & Approach Reviewer
-- Read the commit message deeply to understand the problem being solved
-- Analyze whether this is the right approach to the problem
-- Consider alternative designs and trade-offs:
-  - Are there simpler solutions that achieve the same goal?
-  - Does the approach introduce unnecessary complexity?
-  - Would a different data structure or algorithm be more appropriate?
-- Evaluate whether the change follows existing architectural patterns or
-  introduces new patterns that may be inconsistent
-- Assess the scope: is the change too large? Should it be split into
-  smaller, independently reviewable pieces?
-- Check if the approach has precedent in the codebase or in the academic
-  literature it references (e.g., SuRF paper)
-
-#### Agent: Correctness Reviewer
-- Thread safety and concurrency analysis
-- Error handling and propagation via Status type
-- Edge cases (empty inputs, overflow, boundary conditions)
-- Data corruption scenarios
-- Logic correctness of new algorithms
-- **Behavioral contract changes**: Do return value semantics match what
-  upstream callers expect? (Use the caller-chain analysis from context.md)
-- **Callee side effects**: Does the change call functions that mutate shared
-  state (counters, seqnos, metadata)? Are the mutations correct for the new
-  calling context? (Use the callee-chain analysis from context.md)
-
-#### Agent: Cross-Component & Adversarial Reviewer
-
-This agent exists because the most critical bugs hide at component boundaries,
-not within a single component. It uses a fundamentally different methodology
-than the correctness reviewer: instead of verifying "does the code do what it
-intends?", it asks "what breaks when we change the assumptions?"
-
-**Data-flow analysis:** Perform the cross-component data consumer analysis
-described in section 2g. For every piece of data the change WRITES to a shared
-structure, trace ALL READERS and verify their visibility rules are compatible
-with the writer's assumptions. This is a DATA-FLOW question, not a
-CONTROL-FLOW question — readers may be in completely different subsystems.
-
-**Alternative execution contexts:** Use the canonical table from section 2h.
-Enumerate all contexts where the changed code executes and verify assumptions
-hold in each.
-
-**Assumption stress-testing and assert-breaking:** Follow the methodology from
-section 2i. Identify every design claim, enumerate preconditions, construct
-counterexamples. Treat asserts as hypotheses to break, not proofs.
-**Red flag words**: "logically redundant", "safe because", "no-op",
-"always true", "cannot happen", "invariant holds"
-
-**Callee side-effect audit:** Perform the callee side-effect audit described
-in section 2c. For every callee, ask what it RETURNS and what it MUTATES.
-
-Write findings to `findings-cross-component.md`.
-
-#### Agent: Invariant Adversary
-
-This agent does NOT read the diff in detail. It takes the feature summary and
-systematically tries to break it. While other agents verify "does the code do
-what it says?", this agent asks "what existing system invariants does this
-feature violate?" and "under what inputs do the design claims fail?"
-
-**Steps 1-4: Assumption stress-testing.** Follow the methodology from section
-2i: extract design claims, enumerate preconditions, construct counterexamples,
-and attempt to break every assert. Be exhaustive about input parameter ranges,
-shared state configurations, and concurrent interleaving.
-
-**Step 5: Callee side-effect audit.** Perform the callee side-effect audit
-described in section 2c. For every function the changed code calls, list ALL
-mutations to shared state (atomic CAS loops, counter increments, flag/metadata
-updates, cache invalidation). A function returning `Status::OK()` does NOT
-mean its side effects are correct.
-
-Write findings to `findings-invariant-adversary.md`.
-
-#### Agent: Caller-Context Auditor
-
-This agent traces BACKWARD from every entry point the changed code hooks into.
-While other agents read the changed code forward ("what does it do?"), this
-agent enumerates WHO invokes it and WITH WHAT parameter ranges.
-
-The key insight: a function that is correct for all *typical* inputs may be
-catastrophically wrong for *atypical-but-reachable* inputs. This agent's job
-is to find the atypical inputs.
-
-**Step 1: Identify entry points.** List every function/constructor/method in
-the changed code that receives external input (parameters, config values,
-pointers to shared state). Include:
-- Constructor parameters (e.g., `active_mem`, `read_callback`, `sequence`)
-- Virtual method overrides that callers invoke polymorphically
-- Functions called from multiple subsystems
-
-**Step 2: Enumerate all callers (3-5 levels up).** For each entry point,
-search the codebase for ALL callers. Do NOT stop at the first caller — trace
-the full call chain. Use `Grep` and `Glob` to find:
-- Direct callers of the function
-- Callers of wrapper/adapter functions that forward to it
-- Factory functions that construct the object
-- Virtual dispatch sites (search for the base class method name)
-
-**Step 3: Parameter range analysis.** For each caller, determine:
-- What values does it pass for each parameter?
-- Under what conditions does it call this function?
-- Are there callers that pass unusual values? (e.g., `kMaxSequenceNumber`,
-  `nullptr`, old snapshot seqnos, non-null `read_callback_`)
-
-Build a parameter range table for each entry point, listing all callers
-and the values they pass for each parameter.
-
-**Step 4: Configuration matrix.** Enumerate option/config combinations that
-affect the changed code path:
-- Which options enable/disable the feature?
-- Which options change the execution context? (e.g.,
-  `allow_concurrent_memtable_write`, `use_trie_index`)
-- Are there option combinations that create contradictions?
-
-**Step 5: Cross-reference with context.md.** Compare your caller analysis
-with the invariants and execution contexts documented in context.md. Flag
-any caller that violates an assumed precondition.
-
-Write findings to `findings-caller-audit.md`.
-
-#### Agent: Performance Reviewer
-- Memory allocation on hot paths
-- Unnecessary copies (string, buffer)
-- Cache efficiency and data locality
-- Loop optimization opportunities
-- Branch prediction (LIKELY/UNLIKELY)
-- Zero-overhead design verification
-
-#### Agent: API & Compatibility Reviewer
-- Public API backwards compatibility
-- API consistency with existing patterns
-- Documentation completeness
-- Deprecation policy compliance
-- Forward compatibility (struct extensibility)
-- **Behavioral compatibility**: Do changed semantics (e.g., kOutOfBound vs
-  kUnknown) break implicit contracts with callers?
-
-#### Agent: Serialization & Deserialization Reviewer
-- Format correctness and versioning
-- Alignment requirements
-- Integer overflow in size computations
-- Bounds checking on untrusted data
-- Crafted input attack vectors
-
-#### Agent: Test Coverage Reviewer
-- Edge case coverage
-- Failure mode testing (corruption, truncation)
-- Round-trip testing (build → serialize → deserialize → verify)
-- Integration test coverage
-- **System-level test coverage**: Are the caller-chain interactions tested?
-  (e.g., multi-SST iteration with UDI, level compaction with new behavior)
-- Test quality (no flaky patterns, good assertions)
-
-### 4. Round-Robin Debate Phase
-After all 5 agents complete their initial review, the team lead orchestrates
-a structured debate:
-
-#### Step 4a: Share findings
-- Team lead sends each agent a summary of ALL other agents' findings
-  (or instructs each agent to read the other agents' findings files)
-
-#### Step 4b: Critique round (2 rounds)
-Each agent reviews the findings from the other agents and sends messages to
-challenge, support, or refine them:
-
-- **Challenge**: "I disagree with [agent] [finding] because [evidence]."
-- **Support**: "I independently found the same issue — this confirms it."
-- **Refine**: "[Finding A] is actually a consequence of [Finding B].
-  The root cause is the same."
-
-The debate assignment follows a round-robin pattern:
-```
-correctness-reviewer      →  critiques  →  invariant-adversary, serialization
-cross-component-reviewer  →  critiques  →  correctness, caller-audit
-invariant-adversary       →  critiques  →  correctness, cross-component
-caller-audit              →  critiques  →  invariant-adversary, cross-component
-performance-reviewer      →  critiques  →  api, cross-component
-api-reviewer              →  critiques  →  correctness, performance
-serialization-reviewer    →  critiques  →  correctness, invariant-adversary
-test-reviewer             →  critiques  →  serialization, caller-audit
-design-reviewer           →  critiques  →  cross-component, invariant-adversary
-```
-
-**Note:** The invariant-adversary and caller-audit agents are deliberately
-cross-linked with correctness and cross-component because their findings
-often reveal the same underlying bug from different angles (invariant
-violation vs reachable bad input vs data-flow mismatch).
-
-Each agent should:
-1. Read the assigned agents' findings files
-2. Send a critique message to each assigned agent
-3. Respond to critiques received from other agents
-4. Update their own findings file with any revisions (upgraded/downgraded severity,
-   withdrawn findings, new findings inspired by others)
-
-#### Step 4c: Team lead collects debate results
-- Read all updated findings files
-- Review the debate messages
-- Build consensus: findings supported by 2+ agents → HIGH confidence
-- Write consensus document with final severity classifications
-
-### 5. Consensus Phase
-Team lead synthesizes the debate into a consensus document:
-- Cross-reference overlapping findings across agents
-- Count agreement (majority = 2+ agents independently flagging or supporting)
-- Note disagreements and how they were resolved
-- Classify findings as HIGH/MEDIUM/LOW severity
-- Write consensus document
-
-### 6. Summary Phase
-- Compile all validated findings ordered by severity
-- Include detailed bug analysis (root cause, vulnerable code paths)
-- Include suggested fixes
-- Note which findings were debated and the outcome
-- Output the complete review as your final response text (this becomes the PR
-  comment verbatim), and also overwrite review-findings.md with the identical
-  content as a recovery backstop
-
-**Final report quality rules:**
-- The final report must be CLEAN and POLISHED. No stream-of-consciousness,
-  no "Wait, actually...", no "on closer re-examination". Those belong in
-  the working notes, not the output.
-- If a finding was raised during review but later disproven during debate
-  or deeper analysis, REMOVE IT entirely from the final report. Do not
-  include it with a retraction — just drop it.
-- If a finding was downgraded (e.g., Critical → Suggestion), present it
-  at the final severity only. Do not narrate the severity change.
-- Each finding in the final report should read as a confident, verified
-  conclusion — not a record of the analysis process.
-- The reader should never see the reviewer arguing with itself.
-
-**REQUIRED output structure (so the PR page stays scrollable):**
-
-Your final response — which becomes the PR comment verbatim — (and the
-identical contents of `review-findings.md`) MUST follow this exact structure.
-The summary appears first so reviewers can see HIGH findings at a glance;
-everything else is hidden behind a `<details>` block.
-
-```markdown
-## Summary
-
-<!-- One or two sentences of overall assessment. -->
-
-**High-severity findings (N):**
-- **[file.cc:123]** One-line description of the issue. <!-- repeat per HIGH finding -->
-
-<!-- If there are NO high-severity findings, write exactly: -->
-<!-- _No high-severity findings._ -->
-
-<details>
-<summary>Full review (click to expand)</summary>
-

-
-Rules for this structure:
-- The top-level `## Summary` and the bullet list of HIGH findings MUST stay
-  outside the `<details>` block — they are always visible.
-- Every detail (per-finding root cause, fix, debate outcomes, cross-component
-  analysis, positive observations) MUST live inside the `<details>` block.
-- Do NOT nest a `<details>` inside another `<details>`.
-- Do NOT add any text after the closing `</details>` — the comment-builder

-## Review Checklist
-
-### Context Phase (must be completed before agents spawn)
-- [ ] Subsystem deep-read — read changed files AND surrounding subsystem
-      in depth (logic, edge cases, data flows, locking, concurrency)
-- [ ] Caller chain for every changed public/virtual method (3-5 levels up)
-- [ ] Critical decision points where callers branch on changed behavior

-## Output Structure
-Your **final response text is the primary output** — it becomes the PR comment
-verbatim. The files below are working artifacts and recovery backstops only;
-they are NOT a substitute for outputting the full review in your final response.
-
-Write these artifacts to the working directory root:
-- `review-findings.md` — Recovery backstop: incremental findings appended after
-  each phase, overwritten with the final synthesized review at the end. Used
-  only if the turn limit interrupts the run.
-- `context.md` — Codebase context (call chains, invariants)
-- `findings-*.md` — Per-agent findings (design, correctness, cross-component,
-  invariant-adversary, caller-audit, performance, api, serialization, tests)
-- `consensus.md` — Cross-review consensus (post-debate)

-## Agent Communication Protocol
-
-### During Initial Review (Phase 3)
-- Each agent writes findings to its own file
-- Each agent sends a summary message to team lead when done
-- Agents do NOT communicate with each other yet
-
-### During Debate (Phase 4)
-- Team lead sends each agent a message with instructions to:
-  1. Read the assigned agents' findings files
-  2. Send critique messages to those agents
-  3. Respond to incoming critiques
-  4. Update their own findings file with revisions
-- Each critique message should include:
-  - Which finding they're addressing (e.g., "Correctness F1")
-  - Whether they AGREE, DISAGREE, or want to REFINE
-  - Their reasoning with code evidence
-  - Suggested severity adjustment (if any)
-
-### Message format example
-```
-To: correctness-reviewer
-Re: Your Finding F1
-
-AGREE/DISAGREE/REFINE - [reasoning with code evidence].
-[Suggested severity adjustment if any.]
-```

-## Review Anti-Patterns
-
-These recurring failure modes lead to missed bugs. Each is detailed in the
-referenced section; this table is a quick-reference checklist.
-
-| Anti-Pattern | Fix | Reference |
-|---|---|---|
-| Return-Value Tunnel Vision | Trace callee MUTATIONS, not just returns | Section 2c |
-| Default-Configuration Bias | Enumerate all execution contexts | Section 2h |
-| Assert-as-Proof | Try to BREAK every assert | Section 2i |
-| Write-Path-Only Analysis | Trace data readers, not just writers | Section 2g |
-| Confirmation-Seeking Research | Use adversarial prompts ("find where X fails") | Invariant Adversary agent |
-| Data-Flow vs Control-Flow Confusion | Separate who CALLS from who READS the data | Section 2g |

-# Manual (Local) Code Review — Lightweight Wrapper
-
-## What this is
-
-A resource-light, **single-reviewer** variant of `claude_md/ci_review_prompt.md`
-for running a review by hand in a local Claude Code / Devmate session. It reuses
-the full CI review *methodology* but drops the multi-agent orchestration and the
-CI-only file-persistence machinery, to approximate the heavyweight result at a
-fraction of the cost.
-
-**Scope: LOCAL manual review only. This file is NOT used by CI.** CI uses
-`claude_md/ci_review_prompt.md`.
-
-## How to use
-
-Read `claude_md/ci_review_prompt.md` for the complete methodology — the analysis
-techniques (caller-chain, callee side-effects, cross-component data consumers,
-alternative execution contexts, assumption stress-testing), the per-perspective
-reviewer instructions, the review checklist, and the anti-patterns table.
-
-Then apply that methodology with the OVERRIDES below. **Where this file
-conflicts with `ci_review_prompt.md`, this file wins.**
-
-## Overrides (this is what makes it lightweight)
-
-### 1. Single reviewer — no team, no subagents
-- Do NOT create a team, spawn subagents, or run parallel/background agents.
-- Do NOT run the round-robin Debate phase or the Consensus phase.
-- Instead, YOU personally apply each reviewer role from `ci_review_prompt.md`
-  (Design, Correctness, Cross-Component & Adversarial, Invariant Adversary,
-  Caller-Context, Performance, API/Compat, Serialization, Test Coverage) as
-  sequential *lenses* in one pass. Spend a few focused minutes per lens. Skip
-  lenses that plainly don't apply (e.g., Serialization when there is no on-disk
-  or wire-format change) and note the skip in one line.
-
-### 2. No intermediate files
-- Do NOT write `context.md`, `findings-*.md`, `consensus.md`, or
-  `review-findings.md`. Keep working notes in your reasoning, not on disk.
-- Rationale: those files exist only so CI can recover partial results when an
-  ephemeral runner hits the turn limit — a local session has neither problem.
-  `ci_review_prompt.md` already outputs the review as its final response, so
-  skipping the file loses nothing here.
-
-### 3. Right-size the effort
-- Do the Codebase Context phase, but proportionally: trace the 2-3 most
-  load-bearing call chains and the highest-risk cross-component data consumers,
-  rather than exhaustively enumerating every caller 3-5 levels up.
-- Prioritize the highest-signal lenses for RocksDB: **Correctness**,
-  **Cross-Component & Adversarial**, and **Assumption Stress-Testing**. These
-  catch the bugs that matter most; give them the most attention.
-- Escalation clause: if a thread looks dangerous, go deep on that specific
-  thread even though the overall pass is modest. Modest is the default, not a cap.
-
-### 4. Identify the review target locally
-- Unlike CI, the diff is NOT pre-pasted into this prompt. Determine what to
-  review from the user's request against the local worktree — e.g. the current
-  commit (`git show`), uncommitted changes (`git diff` / `git diff --staged`),
-  a named commit range, or a PR — and read the changed files plus their
-  surrounding context directly from the repo. When in doubt, include all changes
-  not yet upstream, as in
-  `git diff "$(git merge-base upstream/main HEAD 2> /dev/null || git merge-base origin/main HEAD 2> /dev/null)"`
-  plus any untracked files (`git status`) that seem relevant.
-
-## Reminder
-
-The goal is a thorough *single* reviewer, not a 9-agent debate: depth where it
-matters, brevity everywhere else.
