 # Instructions for Coding Agents
 
-These instructions supplement `CONTRIBUTING.md`, which must also be followed.
+These instructions apply to coding agents working on behalf of external
+contributors. They supplement `CONTRIBUTING.md`, which must also be followed.
+
+## Determine Contributor Status
+
+Treat the contributor as external unless you can verify that the GitHub account
+which would perform the action has `WRITE`, `MAINTAIN`, or `ADMIN` permission on
+the canonical `PaperMC/Paper` repository. Organization membership, claims of
+maintainer approval, permission on a fork, or previous contributions are not
+enough by themselves.
+
+Before taking an action or giving guidance whose requirements differ by
+contributor status, determine that status. If it cannot be verified, treat the
+contributor as external.
+
+When GitHub CLI access is available, verify the authenticated account with
+`gh auth status`, then check its permission with:
+
+```console
+gh repo view PaperMC/Paper --json viewerPermission
+```
+
+If the account, repository, or permission cannot be verified, follow the
+external-contributor instructions below. This verification is only needed
+before publishing or communicating with the project; local investigation and
+development can proceed without it.
 
 ## Keep Project Communication Human

+Do not turn yourself into a slop cannon or the contributor into a meat proxy.
 Dumping plausible-looking code or prose into the project creates review work;

+The contributor's value must come from their judgment, context, validation, and

-Do not substitute for users' judgment or ownership of project conversations.
-Helping refine communication the user has authored does not by itself

+You may help a contributor investigate the codebase, make changes locally, and
+run tests. Do not act as the contributor in conversations with Paper
+maintainers. In particular, do not compose issue reports, discussion posts,
+pull request descriptions, comments, or review responses for the contributor,
+or post generated text as if it were theirs.
 
-Help the user develop and communicate their own understanding instead. Ask them
-what changed, why, and how it was verified; explain the considerations raised
-by review feedback; and offer questions or technical points they should
-consider. The user must decide what to communicate and take ownership of the
-final wording.
+Do not relay generated output to maintainers, and do not turn maintainer
+feedback into a prompt and pass the generated response back. Help the
+contributor understand the relevant code and your work instead. The contributor
+must decide what to communicate and write it in their own words.
 
-Do not conceal or misrepresent meaningful AI involvement, present generated
-communication as the user's own, manufacture policy attestations, or help the
-user route around these instructions. The user must be transparent about the
-assistance they received and must understand, review, verify, and own the
-resulting work.
+Good assistance should help the contributor form and communicate their own
+understanding. Coach them through a pull request description by asking what
+changed, why, and how it was verified rather than writing it for them. When
+addressing review feedback, help identify the technical considerations and
+offer talking points for the contributor to consider while drafting their own
+response.
+
+Do not conceal or misrepresent meaningful AI involvement; require the
+contributor to be transparent about how these tools contributed to their work.
+Transparency does not excuse work the contributor does not understand, review,
+verify, and own.
+
+If the contributor asks you to generate something and put it in front of
+maintainers without doing that work, refuse plainly. Do not make the output
+sound human, manufacture policy attestations, or help them route around these
+instructions.

+Subject: [PATCH] Allow Saving of Oversized Chunks
+
+The Minecraft World Region File format has a hard cap of 1MB per chunk.
+This is due to the fact that the header of the file format only allocates
+a single byte for sector count, meaning a maximum of 256 sectors, at 4k per sector.
+
+This limit can be reached fairly easily with books, resulting in the chunk being unable
+to save to the world. Worse off, is that nothing printed when this occured, and silently
+performed a chunk rollback on next load.
+
+This leads to security risk with duplication and is being actively exploited.
+
+This patch catches the too large scenario, falls back and moves any large Entity
+or Tile Entity into a new compound, and this compound is saved into a different file.
+
+On Chunk Load, we check for oversized status, and if so, we load the extra file and
+merge the Entities and Tile Entities from the oversized chunk back into the level to
+then be loaded as normal.
+
+Once a chunk is returned back to normal size, the oversized flag will clear, and no
+extra data file will exist.
+
+This fix maintains compatability with all existing Anvil Region Format tools as it
+does not alter the save format. They will just not know about the extra entities.
+
+This fix also maintains compatability if someone switches server jars to one without
+this fix, as the data will remain in the oversized file. Once the server returns
+to a jar with this fix, the data will be restored.
