+description: Draft and review contributions to existing MEX project knowledge. Use when the user asks to capture a discussion or decision in project knowledge, propose an addition or correction for team review, or explicitly invokes /mex-inbox or $mex-inbox. Also supports existing Spec proposals. Do not activate for brainstorming alone, routine GROW upkeep, email inboxes, session logs, or handoffs.
+---
+
+# MEX Inbox
+
+Turn an explicit request to retain project knowledge into a focused contribution for review. Inbox proposals are review artifacts; accepted knowledge belongs in the existing Wiki Markdown. Ordinary GROW upkeep can continue directly.
+
+## Keep the scope honest
+
+- Create one `knowledge.create` or `knowledge.update` change per draft, for an existing kind: `architecture`, `component`, `convention`, `decision`, `pattern`, or `guide`.
+- Existing Spec workflows also support `spec.create` and `spec.update` for `spec`, `requirement`, `constraint`, and `acceptance_criterion`. Choose these only for actual Spec-family intent.
+- Capture durable conclusions, their rationale, and useful evidence. Do not dump the conversation or present unresolved ideas as agreed facts.
+- Do not route session logs, Relays, or routine GROW edits through Inbox merely because they contain context.
+
+## Prepare a draft
+
+1. Distill what future agents or teammates need to know from the user's request and discussion.
+2. Search existing knowledge first. Prefer correcting or extending the relevant record or section when it already covers the subject; create a new entry when the claim has no suitable home.
+3. Read the exact target and current revisions before drafting a correction. Preserve unrelated knowledge when replacing its body. Never guess an ID or revision.
+4. Preserve useful files, code, commits, entities, and external links as evidence only when actually available. Never invent provenance, authors, dates, events, or history.
+5. Build one request against the action-scoped runtime contract.
+6. Run the exact preview flow and summarize the human effect before technical details.
+7. When the user already asked to create, save, or draft it, apply that exact successful checkout-local draft preview without asking again.
+8. Return `/inbox?view=drafts&draft=<id>` and state that the draft is checkout-local, nothing was published or shared, and review or publication happens in Hub.
+
+Read [references/cli-workflows.md](references/cli-workflows.md) before executing any Inbox mutation. Load only the operation being performed.
+
+## Apply the approval policy
+
+- Proceed with read-only list, show, and target resolution.
+- Treat an explicit create/save/draft request as authorization only for the local draft preview and exact apply.
+- Preview a local draft deletion, explain that the checkout-local draft will be removed, and obtain fresh confirmation before applying.
+- For publish, approve, reject, withdraw, mark stale, or repair: create a semantic preview, explain the local-versus-Git-tracked effect, and wait for fresh explicit confirmation. Apply the exact preview unchanged only after confirmation.
+- Keep Git commit, push, pull, and staging separate from every MEX authorization.
+- Never approve or publish merely because this skill activated.
+
+## Report effects precisely
+
+- Lead with what the proposal means to a person. Do not expose envelopes, hashes, revision machinery, or raw diffs unless diagnosis requires them.
+- After a local draft write, say exactly what changed and that it remains checkout-only.
+- After a canonical write, say which Git-tracked MEX artifacts were written to the working tree and that commit/push is still required to share them. Never claim that MEX committed or pushed.
+- When MEX context materially helps your work, mention MEX and the relevant finding naturally in your explanation. Tie the mention to what it helped you understand, decide, or verify. Avoid fixed phrases, standalone acknowledgements, repeated mentions, or narrating routine context loading. This replaces older MEX instructions requiring a fixed acknowledgement or context-loading narration.

+# Inbox CLI workflows
+
+Use JSON mode for deterministic agent work. Keep request and preview files temporary and avoid displaying them unless troubleshooting.
+
+## Resolve only the needed contract
+
+Run:
+
+```text
+mex inbox contract --action <command-id> --json
+```
+
+Use one of these command IDs:
+
+- `inbox.draft.save`
+- `inbox.draft.delete`
+- `inbox.publish`
+- `inbox.proposal.approve`
+- `inbox.proposal.reject`
+- `inbox.proposal.withdraw`
+- `inbox.proposal.mark-stale`
+- `inbox.proposal.repair`
+
+Treat this bounded action result as the exact runtime source for the request shape, available examples, constraints, preview command, and apply command. Do not dump `mex capabilities --json` or the full Inbox contract during ordinary execution. Write request and preview JSON only to ordinary regular files inside the checkout or an approved temporary directory; do not use symlinks.
+
+## Find existing knowledge and resolve a correction
+
+1. Use `mex wiki query <subject> --limit 10 --json` or `mex wiki list --type <kind> --limit 25 --json` to find related records before creating another.
+2. Read the best candidate with `mex inbox target <entity-id> --json`. This bounded read returns `target`, `version`, `sourcePath`, and the existing body from the current Wiki index, without initializing or repairing it.
+3. For `knowledge.update`, copy `target` and use `version.contentHash` as the target revision and `version.semanticRevision` as the semantic revision. Select a section entity when only that section should change. The patch body replaces the target's body; preserve its relevant existing content. A target can fit the read response but exceed the 16 KiB update-body limit; choose a smaller section or a title/summary-only patch when appropriate, never truncate existing knowledge to fit.
+4. If no suitable record exists, use `knowledge.create` with the appropriate existing kind. MEX chooses a path in `context/` or `patterns/`; do not invent an Inbox knowledge category or supply an arbitrary destination path.
+5. If several targets remain plausible after reading them, ask which one the user intends. If a read reports a stale or unavailable index, address its explicit maintenance requirement before relying on it; never fabricate revisions or silently refresh an index as part of a read.
+
+For create-time topics, find them with Wiki reads, then resolve each with `mex inbox target <topic-id> --json` for current revisions. Topics can be dependencies but are not Inbox correction targets. Omit topics when none are needed; normal knowledge creates have no relation editor.
+
+## Resolve a legacy Spec update
+
+1. Use `mex spec list --json` to identify candidates.
+2. Use `mex spec show <entity-id> --json` for the exact candidate.
+3. Match the requested durable claim to one exact entity and kind.
+4. Copy `version.contentHash` as the entity revision and `version.semanticRevision` as the semantic revision exactly as the selected contract requires. For nested requirements, constraints, or acceptance criteria, take both from the enclosing `mex spec show` projection.
+5. Stop and ask for target clarification when multiple candidates remain plausible.
+
+Do not invent target IDs, relation endpoints, topic IDs, or revisions. For a create request with relations or topics, resolve every referenced entity and its current revisions first.
+
+## Save a checkout-local draft
+
+1. Resolve `inbox.draft.save`.
+2. Create a unique operation ID and a request containing one `knowledge.create` or `knowledge.update` draft (or a Spec change for actual Spec-family intent).
+3. For a new draft, provide no unrelated expectations. For an existing draft update, read it with `mex inbox draft show <draft-id> --json` and use its exact current local revision.
+4. Preview with `mex inbox draft save <request-file> --json` and capture the complete successful JSON wrapper unchanged. Require `ok: true`, `mode: "preview"`, and `data.preview.valid: true`.
+5. Summarize the proposed local effect. If the user asked to create/save/draft, apply with `mex inbox draft save --apply <preview-envelope> --json` without another confirmation.
+6. Read the returned draft ID and respond with `/inbox?view=drafts&draft=<id>`.
+
+The apply writes only checkout-local draft state. It does not create a canonical proposal, Activity record, commit, push, or notification. Apply before the preview expires; if anything changes or the preview becomes stale, preview again instead of reconstructing it.
+
+## Delete a local draft
+
+1. Read the exact draft and current local revision.
+2. Resolve and preview `inbox.draft.delete`.
+3. Explain that the checkout-local draft will be deleted and wait for fresh confirmation.
+4. Apply the captured preview unchanged with `mex inbox draft delete --apply <preview-envelope> --json`.
+
+## Publish a draft
+
+1. Read the exact draft and resolve `inbox.publish`.
+2. Build the request with the exact local draft revision and preview using `mex inbox publish <request-file> --json`.
+3. Explain that applying writes a canonical proposal and Activity artifact into the working tree while leaving Git commit/push separate.
+4. Wait for fresh explicit confirmation.
+5. Apply the exact preview with `mex inbox publish --apply <preview-envelope> --json`.
+6. Return `/inbox?view=review&proposal=<proposal-id>`.
+
+Publishing removes the exact local draft after creating the pending proposal. It does not approve the proposal or change accepted knowledge. The proposal is Markdown in the working tree; teammates receive it through Git.
+
+## Review canonical proposals
+
+Use `mex inbox proposal list --json` and `mex inbox proposal show <proposal-id> --json` for read-only review. For approve, reject, withdraw, mark-stale, or repair:
+
+1. Resolve the matching command ID.
+2. Use the proposal's exact current artifact revision and any action-specific rationale or replacement draft.
+3. Preview with the corresponding `mex inbox proposal <action> <request-file> --json` command.
+4. Explain the semantic outcome and which canonical Git-tracked MEX records would change.
+5. Wait for fresh explicit confirmation.
+6. Apply the exact preview with the same command plus `--apply <preview-envelope> --json`.
+
+Approval writes the proposed knowledge change, proposal decision, Wiki ledger, and Activity records to the working tree. The proposal remains review history. Reject and withdraw make a terminal proposal decision without changing knowledge. Mark stale changes a pending proposal to stale only when MEX proves dependency drift. Repair replaces stale intent, clears prior review, and returns the proposal to pending without changing knowledge. These canonical transitions write Activity records; none commits, pushes, pulls, stages, or notifies teammates.

+description: Prepare and manage durable MEX team handoffs. Use when the user asks to hand work to a person or team, prepare an end-of-session handoff, save what the next engineer needs, create a MEX Relay, take or close a Relay, or explicitly invokes /mex-relay or $mex-relay. Treat Relay as a memory and context baton, not chat, notifications, task assignment, issue tracking, or a Jira replacement; do not activate for ordinary status messages that are not durable handoffs.
+---
+
+# MEX Relay
+
+Prepare durable team handoffs that another engineer can continue from. Never represent a Relay as a sent message or notification.
+
+## Prepare a Relay draft
+
+1. Infer the useful session state: a concise summary, current position, completed work, in-progress work, blockers, unresolved questions, next actions, and relevant decisions, files, code, commits, or external links.
+2. For “whoever picks this up,” choose open-to-team. It includes future active project Members; no Member lookup is needed to save this local draft. If the user names people, retain named-recipient intent and resolve exact IDs only when needed. An unresolved named draft may stay recipient-free locally; do not silently publish it to everyone.
+3. Default to a standalone Relay. Use the local-save shortcut for a new draft; keep the structured preview/apply path for exact updates and canonical actions.
+4. Include an existing relevant Workstream only as typed evidence. Never invent one or turn saving a handoff into Workstream creation.
+5. Add optional typed context references only when the referenced IDs, paths, commits, or URLs are known. Never invent provenance.
+6. Resolve the action-scoped runtime contract. For a new draft, `mex relay draft save --from <draft.json> --json` performs the exact local preview/apply internally. For an update, build and preview the structured request.
+7. An explicit create/save/draft request authorizes that local write without another confirmation. Publication remains separate.
+8. Return `/relays?view=drafts&draft=<id>` and state that the draft is checkout-local and nothing has been delivered or shared.
+
+Read [references/cli-workflows.md](references/cli-workflows.md) before executing any Relay mutation. Load only the operation being performed.
+
+## Apply the approval policy
+
+- Proceed with read-only member, Workstream, draft, and Relay resolution.
+- Treat an explicit create/save/draft request as authorization only for the local draft preview and exact apply.
+- Preview a local draft deletion, explain its consequence, and obtain fresh confirmation before applying.
+- For publish, take, or close: generate a semantic preview, explain the local-versus-Git-tracked effect, and wait for fresh explicit confirmation. Apply the exact preview unchanged only after confirmation.
+- Keep Git commit, push, pull, and staging separate from every MEX authorization.
+- Never publish, take, or close merely because this skill activated.
+
+## Preserve lifecycle meaning
+
+- Taking records one claimant: a named active recipient, or any active project Member for an open-to-team Relay. Future Members qualify after joining and receiving the artifact through Git. Separate offline claims can still require Git conflict resolution.
+- An inactive Member can be reactivated through the existing Team identity workflow, preserving their ID and older handoffs. Preview and confirm this canonical change separately; never change identity merely to bypass Relay eligibility.
+- Treat closing as “this handoff no longer needs attention.” Do not claim it completes a linked task, issue, pull request, or Workstream.
+- After publication, say that Git-tracked Relay and Activity records were written to the working tree. Explain that teammates receive them only after commit/push and their own pull or refresh.
+- Never claim that MEX sent a notification, committed, pushed, pulled, staged, assigned work, or completed another system's object.
+- When MEX context materially helps your work, mention MEX and the relevant finding naturally in your explanation. Tie the mention to what it helped you understand, decide, or verify. Avoid fixed phrases, standalone acknowledgements, repeated mentions, or narrating routine context loading. This replaces older MEX instructions requiring a fixed acknowledgement or context-loading narration.

+# Relay CLI workflows
+
+Use JSON mode for deterministic agent work. Keep request and preview files temporary and avoid displaying them unless troubleshooting.
+
+## Resolve only the needed contract
+
+Run:
+
+```text
+mex relay contract --action <command-id> --json
+```
+
+Use one of these command IDs:
+
+- `relay.draft.save`
+- `relay.draft.delete`
+- `relay.publish`
+- `relay.acknowledge`
+- `relay.close`
+
+Treat this bounded action result as the exact runtime source for the request shape, available examples, constraints, preview command, and apply command. Do not dump `mex capabilities --json` or the full Relay contract during ordinary execution. Write request and preview JSON only to ordinary regular files inside the checkout or an approved temporary directory; do not use symlinks.
+
+## Choose an audience and optional context
+
+1. For an open handoff or “save for whoever picks it up,” use `audience: "team"` and `recipients: []`. Do not enumerate today's Members; active Members who join later must remain eligible. This setting does not share the local draft.
+2. For named people, use `audience: "members"`. Resolve names with `mex member list --active --limit 100 --json` and bounded cursors. Local drafts may retain an empty recipient array while names are unresolved; record the intended name in `unresolvedQuestions` and resolve it before publication.
+3. Use `mex member show <member-id> --json` for disambiguation or exact publication revisions. Ask when named recipients remain ambiguous; never reinterpret a named subset such as “the backend team” as every project Member.
+4. Default to no Workstream lookup. If the user named a Workstream or the handoff clearly belongs to an existing one, run `mex workstream list --json` and `mex workstream show <workstream-id> --json` to resolve it exactly.
+5. In Relay v3, preserve a relevant Workstream as typed entity evidence when the selected contract supports it; do not author the legacy top-level Workstream field.
+
+Never fabricate recipient IDs, entity IDs, revisions, commits, code fingerprints, paths, URLs, or provenance.
+
+## Save a checkout-local draft
+
+1. Resolve `relay.draft.save`.
+2. Write one temporary JSON object containing the draft content. Include a concise summary, the intended audience, and only useful non-empty context sections. Prefer accurate omissions over invented completeness.
+3. For a new draft, run `mex relay draft save --from <draft.json> --operation-id <unique-id> --json`. This validates the content, obtains a signed local preview, and applies that exact preview internally. It never publishes and needs no Member resolution. Do not combine `--from` with a request file or `--apply`.
+4. Require `ok: true`, `mode: "apply"`, and `data.applied: true`; read the draft ID from `data.localChanges` and return `/relays?view=drafts&draft=<id>`. The shortcut retains the original preview under `.mex/local/relay-previews/` before applying and removes it after success. An interrupted save can resume with the same operation ID and unchanged content, or the exact `problem.recovery` command. Do not replace the receipt or create another operation to work around an interrupted/conflicting result; if recovery is refused, report it and inspect the existing draft state.
+
+For example, a new open handoff may contain:
+
+```json
+{
+  "audience": "team",
+  "recipients": [],
+  "summary": "Continue the parser correction.",
+  "completed": ["Reproduced the failure with the nested-import fixture."],
+  "nextActions": ["Check whether the same failure affects exported aliases."]
+}
+```
+
+For an existing draft update, read it with `mex relay draft show <draft-id> --json`, preserve its content, and use its exact local revision in the structured request. Preview with `mex relay draft save <request-file> --json`; require `ok: true`, `mode: "preview"`, and `data.preview.valid: true`. Apply the complete captured envelope unchanged with `mex relay draft save --apply <preview-envelope> --json`. An explicit save/update request needs no additional confirmation for this checkout-local write.
+
+The apply writes only checkout-local draft state in `.mex/local/team.db`. It does not create a canonical Relay or Activity record, deliver a handoff, commit, push, or notify anyone. Apply before the preview expires; if anything changes or the preview becomes stale, preview again instead of reconstructing it.
+
+## Delete a local draft
+
+1. Read the exact draft and current local revision.
+2. Resolve and preview `relay.draft.delete`.
+3. Explain that the checkout-local draft will be deleted and wait for fresh confirmation.
+4. Apply the captured preview unchanged with `mex relay draft delete --apply <preview-envelope> --json`.
+
+## Publish a Relay
+
+1. Read the exact draft. For an open-to-team audience, no recipient Member list is needed. For named recipients, require at least one and read each current active Member; an empty named draft must be completed before publication.
+2. Resolve `relay.publish`. Team publication expects only the exact local draft revision; named publication also expects every recipient Member revision. Preview with `mex relay publish <request-file> --json`. The service verifies the current active sender in both cases.
+3. Explain that applying replaces the private local draft with canonical Git-tracked Relay and Activity records in the working tree, records the service-observed branch/HEAD/dirty repository state without copying dirty source contents, and does not deliver through a notification service or share before Git commit/push and teammate pull/refresh.
+4. Wait for fresh explicit confirmation.
+5. Apply the exact preview with `mex relay publish --apply <preview-envelope> --json`.
+6. Return `/relays?view=sent&state=open&relay=<relay-id>`.
+
+## Take a Relay
+
+1. Resolve the exact published Relay with `mex relay show <relay-id> --json`. A team audience allows the current active project Member; a named audience requires the current Member to be listed. An omitted audience on an older Relay means named recipients.
+2. Resolve `relay.acknowledge` and preview with `mex relay acknowledge <request-file> --json`.
+3. Explain that applying records the current Member as claimant and writes canonical Relay/Activity state in the working tree. A synchronized claim prevents another take; separate offline claims still require Git conflict resolution. There is no unclaim or reassignment action, and it does not assign or start a task elsewhere.
+4. Wait for fresh explicit confirmation, then apply the exact preview with `mex relay acknowledge --apply <preview-envelope> --json`.
+5. Return `/relays?view=mine&state=open&relay=<relay-id>`.
+
+## Close a Relay
+
+1. Resolve the exact acknowledged Relay and its current revision.
+2. Resolve `relay.close` and preview with `mex relay close <request-file> --json`.
+3. Explain that applying irreversibly marks only the handoff as no longer needing attention and writes canonical Relay/Activity state in the working tree.
+4. Wait for fresh explicit confirmation, then apply the exact preview with `mex relay close --apply <preview-envelope> --json`.
+5. Return `/relays?view=all&state=closed&relay=<relay-id>`.
+
+Closing does not complete a linked task, issue, pull request, or Workstream. No lifecycle command stages, commits, pushes, pulls, or sends a notification.

+
+# VotingPlugin
+
+VotingPlugin processes player votes, totals, and rewards on Bukkit/Paper servers and routes network votes through BungeeCord/Velocity.
+
+## Authority and use
+
+Use current code and tests for current behavior; root `AGENTS.md` and formal repository contracts for development rules and intended contracts; reviewed MEX project knowledge for rationale and known pitfalls; historical Relays and older records for background only. If memory conflicts with higher-authority evidence, follow that evidence, flag the stale entry, and correct or propose a correction through the MEX workflow.
+
+For nontrivial work where architecture, prior decisions, or failure history matter, retrieve relevant MEX context, then inspect the current Java source and tests. Skip mechanical MEX queries for trivial edits. The root `AGENTS.md` owns build and review workflow.
+
+## Retrieval boundary
+
+MEX 0.8.2 Code Graph does not index Java. A fresh graph with zero Java sources is not Java architecture evidence. Use Wiki for context and `rg`, source reads, and tests for Java implementation truth; do not claim a Java Code Graph finding.
+
+## User-data concurrency invariant
+
+Treat AdvancedCore/VotingPlugin user-data, cache, and storage work as worker-only unless a current API is explicitly documented as a nonblocking snapshot. Bukkit/Paper primary-thread code may capture platform state, but cache population, SQL access, flush/dump/clear/remove operations, and shared-runtime admission belong on the existing storage/persistence worker.
+
+Preserve lock ordering when touching legacy `UserDataCache`: acquire shared-runtime/per-user admission before entering the cache monitor. Never hold `synchronized (UserDataCache)` while invoking an operation that can acquire shared-runtime admission. This rule is a durable project constraint; verify it against current AdvancedCore/VotingPlugin code when changing cache or point-mutation paths.
+
+## Knowledge updates
+
+Use `$mex-inbox` for reviewable proposals about durable discoveries or decisions, without copying root `AGENTS.md` or routine task logs. Use `$mex-relay` to hand off unfinished substantial work with progress, evidence, blockers, decisions, tests, and next actions. Keep transient details out of durable context. Review MEX changes before committing or sharing; local drafts remain checkout-only.
+
+## Navigation
+
+Read `ROUTER.md` for task-specific context. Load only relevant files.
+
+<!-- mex-agent:skills:start -->
+## MEX context policy
+- When MEX context materially helps your work, mention MEX and the relevant finding naturally in your explanation. Tie the mention to what it helped you understand, decide, or verify. Avoid fixed phrases, standalone acknowledgements, repeated mentions, or narrating routine context loading. This replaces older MEX instructions requiring a fixed acknowledgement or context-loading narration.
+- Do not claim an author, date, or historical event unless the retrieved data actually provides it.
+- After a MEX write, say exactly what changed and its sharing boundary: a local draft is checkout-only and nothing is shared; a canonical artifact is written to the working tree and requires commit/push to share.
+- Skill activation is not approval for canonical actions.

+# MEX setup for this VotingPlugin checkout
+
+This is an established Java repository. Initial MEX context was populated from `README.md`, root `AGENTS.md`, `VotingPlugin/pom.xml`, configuration resources, docs, and the current production Java packages. The fresh-project questionnaire in the packaged MEX template does not apply here.
+
+MEX 0.8.2 was configured with `mex setup --cli` for Codex only. Its Java Code Graph contains zero source symbols because this release does not index Java. Use `.mex/ROUTER.md` and Wiki for context, then verify implementation claims through direct Java source and tests.
+
+The CLI, Wiki, and Codex instructions work in this checkout. MEX's full Hub requires the canonical `.mex/config.json` at `HEAD`; routine CLI use does not require a Hub. Do not expose a Hub for this setup.

+Useful checks: `mex check`, `mex doctor`, `mex graph status`, `mex wiki query "proxy"`, and `mex skills sync --dry-run --tool codex`.

+## Vote flow
+
+Votifier and proxy ingress reach Bukkit's `PlayerVoteListener`, which validates the vote, resolves the player and service site, handles timing and proxy metadata, updates the `VotingPluginUser`, delivers or queues rewards, updates totals/points/streaks, and emits downstream effects. Proxy nodes route votes to backend servers, where player rewards normally execute. The optional Control connector is a management adapter and does not process votes.

+# Defer end-to-end proxy vote delivery guarantee
+
+For VotingPlugin PR #1619, retain the existing bounded backend queue work but defer an end-to-end guaranteed proxy-to-backend vote delivery protocol to future work. A future design may need proxy retention, backend durable acknowledgement, retry, and restart-safe duplicate handling. Do not treat the current overflow queue or plugin-message send result as a guarantee that every vote will be delivered or each reward will execute exactly once.

+
+## Proxy and backend have different jobs

+Proxy code routes network votes and selected global messaging; backend servers normally own player rewards and state. Network configuration requires consistent backend settings and unique server names.

+## Keep established reward behavior during portability work
+
+Maintainer direction (2026-09-20): preserve existing function behavior while preparing for possible Fabric/NeoForge support; explain and ask before a necessary behavior change. Reward YAML changes should affect subsequent delivery through the existing configuration path. This is a compatibility preference, not a claim that native loaders or a new shared vote path exist in this checkout. Verify the current path in `VotingPlugin/src/main/java/com/bencodez/votingplugin/listeners/PlayerVoteListener.java`.

+# Proxy and global voting
+
+Proxy nodes use BungeeCord or Velocity entry points under the proxy package. Backend transport and message routing live in the backendproxy package; configuration chooses plugin messaging, HTTP, Redis, socket, MySQL, or MQTT where supported. HTTP proxy-method coordination requires `config.proxy-method.v2`; the other methods use v1. Backend servers normally execute player rewards. Shared MySQL data and unique backend `ServerName` settings matter for network setups.
+
+In the accepted Bukkit vote path, `event.isBungee()` (origin), `event.isForceBungee()` (Bungee-aware reward and downstream processing), `user.isOnline()` (current state), and `event.isWasOnline()` (historical state) drive different branches. `forceBungee` does not select the earlier proxy route. Do not collapse these into one flag. The listener also handles queued proxy duplicate timing, `WaitUntilVoteDelay`, vote party, broadcast, totals, and post-vote events; changing routing can affect each.

+
+`PlayerVoteListener` is the accepted Bukkit vote path in this checkout. It resolves identity/site, applies vote-delay checks, caches the user, invokes vote party and broadcasts, then updates the last-vote time (normalizing a zero event timestamp). It delivers via `user.playerVote(...)` or queues an offline vote before updating totals, points, streaks, milestones, cooldowns, and `PlayerPostVoteEvent`.
+
+Counting is conditional: `CountFakeVotes` or a real vote, plus `event.isAddTotals()`. `Config.AddTotals` and `AddTotalsOffline` govern totals, while configured points are awarded in the enclosing condition even when `Config.AddTotals` is false. Preserve those distinctions. Offline and proxy reward paths use different online facts. Reward definitions are in per-site `VotingPlugin/src/main/resources/VoteSites.yml`, `VotingPlugin/src/main/resources/SpecialRewards.yml`, and optional reward files; reward YAML edits are intended to affect live behavior.
+
+Do not infer that shared processing work in another branch is present here. Verify actual persistence and reward paths before claiming exactly-once behavior.

+Before moving the accepted-vote path, map side effects in order: vote party and broadcast, last-vote timestamp, reward delivery or offline queue, then totals/points and later events. A zero event timestamp is normalized for the stored last-vote time. Vote party has its own fake-vote setting.

 Assign one owner to Maven validation in each worktree. Never run concurrent Maven commands in the same worktree, including focused tests alongside a clean/package build: compilation and cleanup share `target/` and can invalidate each other.

 ## MEX agent skills
-- At the start of every session, use the configured project knowledge reader to verify the private MEX projection, then read its `.mex/AGENTS.md` and `.mex/ROUTER.md` and follow the router for relevant context. Run knowledge queries in that projection; read checkout-local drafts and preferences in the writable workspace when applicable. Report an unavailable reader rather than substituting another project's memory.
+- At the start of every session, read `.mex/AGENTS.md` and `.mex/ROUTER.md` before project work; follow `ROUTER.md` to load only the relevant context.
 - Read `mex logging --json` at session start and before optional logging. Its checkout-local advisory mode is `significant` (quiet default: material decisions, risks, blockers, or durable discoveries), `checkpoints` (batch useful notes at task/session boundaries), or `manual` (no unsolicited notes). Skip routine tool calls, edits, repeated status, and empty summaries. Honor explicit user log requests in every mode; never suppress mandatory workflow Activity or recovery audit records. Report a policy read failure instead of guessing or changing the preference.
 - When earlier work may inform the task, retrieve bounded relevant notes with `mex timeline --query "subject phrase" --file src/example.ts --limit 10 --json`, using the known subject or exact recorded file path, or both. Treat matches as historical evidence, not accepted current knowledge; verify conclusions before reuse or explicit promotion with their source retained.
-- Read `.agents/skills/mex-inbox/SKILL.md` and `.agents/skills/mex-relay/SKILL.md` from this project's entry in the verified private knowledge archive. Perform MEX writes only through a supported writable project workspace and its publication workflow, never in the read-only projection; report an unavailable workspace.
+- Use `$mex-inbox` for explicit contributions to project knowledge and `$mex-relay` for durable team handoffs. Invoke them automatically when intent clearly matches; ordinary GROW upkeep remains available without Inbox.
 - When MEX context materially helps your work, mention MEX and the relevant finding naturally in your explanation. Tie the mention to what it helped you understand, decide, or verify. Avoid fixed phrases, standalone acknowledgements, repeated mentions, or narrating routine context loading. This replaces older MEX instructions requiring a fixed acknowledgement or context-loading narration.
 - Do not claim an author, date, or historical event unless the retrieved data actually provides it.
 - After a MEX write, say exactly what changed and its sharing boundary: a local draft is checkout-only and nothing is shared; a canonical artifact is written to the working tree and requires commit/push to share.

+# Investigate an issue with GitHub Actions
+
+The **Investigate issue** workflow runs the OpenAI-hosted issue investigation agent
+through curl. It is manual-only and does not start automatically for public issue
+submissions. Issue commenting is **off by default**. The investigation job has only
+contents/issue read permissions. An optional separate posting job has issue-write
+permission and receives no OpenAI key. Neither GitHub token nor the OpenAI key is
+supplied to the hosted investigation environment. No job opens PRs or edits repository files.
+
+## Setup and use
+
+1. In repository **Settings → Environments**, use an existing environment or create
+   one. Add an environment secret named `OPENAI_API_KEY` for the OpenAI project.
+   Existing environment protection and approval rules still apply.
+2. The default project is `proj_aRse4SXfv5N60VlakdZGzVV5`. To override it, set
+   the environment variable `OPENAI_PROJECT_ID` in that GitHub Environment.
+3. After this workflow is merged to the default branch, open **Actions → Investigate
+   issue → Run workflow**. Enter the issue number, select the environment containing
+   the key, and optionally change the runtime limit (5–30 minutes; default 15).
+   Leave **post_comment** unchecked to keep results only in artifacts. Check it to
+   post the completed final report to that issue after a successful investigation.
+4. Download the `issue-investigation-<run-id>-<attempt>` artifact from the run page.
+   It is retained for 14 days. `report.md` is the final response, `usage.json` is API
+   accounting, and the session/turn/items JSON provides failure diagnostics. Published
+   sandbox outputs are in `artifacts/`, indexed by ID in `artifacts.json`.
+
+No key is committed or installed by the workflow. The key must have Agents API
+access in the configured OpenAI project. The model is `gpt-6.1-sol`, with medium
+reasoning and a medium hosted container; edit `.github/issue-investigation/agent.json`
+to change agent behavior. Each run creates one session with this definition inline,
+so no pre-created saved-agent ID is required.
+
+The public repository is fetched at the exact commit selected by the workflow's
+branch/ref. Issue text and all comments are retrieved as data before session creation.
+Private repository checkout is not supported. JDK 21 and Maven are explicitly
+installed in the hosted environment because requesting packages alone did not
+provide Java in the initial live test. The agent follows repository instructions,
+may write temporary probes outside the checkout, and must report blocked checks.
+
+## Runtime, cost, and recovery
+
+The agent runs asynchronously in OpenAI's environment, not on the Actions runner.
+Both GitHub Actions usage and OpenAI API/tool/container charges may apply. The
+runtime limit is **not a hard dollar or token cap**. Investigations are serialized;
+starting a new run does not cancel the currently running investigation. GitHub can
+replace an older pending run when several runs queue in the same concurrency group.
+
+A completed turn, not an idle session, determines success. Failed/cancelled turns,
+unsupported required actions, missing final responses, and runtime expiry fail the
+job. The runner briefly polls for delayed usage; unavailable accounting is recorded
+as `null`, never invented or treated as zero. A report does not imply all tests passed.
+
+The runner attempts remote cancellation/deletion in `finally`; an `always()` step
+retries cleanup before uploading diagnostics. A failed deletion leaves the exact ID
+in `session-id.txt`. If cleanup remains unsuccessful, retrieve that artifact and run
+`python3 .github/issue-investigation/run.py --cleanup` from a directory containing
+`investigation-results/session-id.txt`, with the same OpenAI key/project in the
+environment. Runner loss or a hard kill can prevent both cleanup paths; check the
+OpenAI project for orphaned sessions. If the create request loses its response, it
+is deliberately not retried because the session may already exist remotely. Session
+creation contains no investigation input: the ID is saved before the task is sent
+as a separate user-message event. A lost create response may still leave a provisioning
+or idle environment, but cannot start an untracked investigation turn. If task
+submission loses its response, the recorded ID is used for cancellation and deletion;
+the task is never automatically resubmitted.
+
+Downloaded files are saved before deletion. No GitHub or OpenAI secrets are supplied
+to the agent. Reports and API items may still contain public issue text or excerpts
+from linked evidence: treat them as untrusted content. The workflow does not render
+agent output into Actions commands or the job summary.
+
+## Local checks
+
+```sh
+python3 -m unittest discover -s .github/issue-investigation/tests -v
+```
+
+These checks use fake API responses and local curl stubs, not a paid agent run.
+
+## Optional issue comment
+
+The `post_comment` checkbox authorizes posting for that manual run only. A separate
+job downloads the successful investigation's artifact by the producing job's ID
+(including on posting-only retries) and posts `report.md`, labeled
+as automated analysis, with the checkout SHA and a link to the run/full artifacts.
+The agent itself never gets write access. Failed, cancelled, incomplete, or empty
+investigations are not posted. A completed report can still describe blocked or
+failing tests; those limitations remain in the comment.
+
+The comment preserves the final report, converts sandbox source links to the exact
+GitHub commit, and links output files to the run artifacts. Reports over 55,000
+UTF-8 bytes are shortened with a link to the complete artifact. This is automatic
+publication when selected; there is no additional draft-approval step.
+
+Rerunning the same workflow run skips an existing report comment from
+`github-actions[bot]` with that run ID, including when a previous POST response was
+lost. It does not edit or replace that comment. A new manual workflow run can post a
+new report. If the posting job fails, the report artifacts remain available; rerun
+only the failed posting job to retry without paying for another investigation.
