Summary

  • preserve the active account address when callers override only author display fields
  • reconcile canonical publication numbers and short author addresses in settled non-updating comment snapshots
  • document both guarantees and add regression coverage

Closes #108


Note

Medium Risk
Touches comment publishing author assembly and frozen useComment merge logic, which affects signed metadata and what users see after publish; changes are narrow and covered by new tests.

Overview
Fixes two publication and display edge cases around author identity and frozen comment snapshots (autoUpdate: false).

Publishing: publishComment now builds publicationAuthor by merging optional author overrides onto the active account author, so overrides like displayName no longer wipe the account’s address or comment-chain previousCommentCid. If the override uses a different author address and does not explicitly set previousCommentCid, the inherited chain link is removed so another identity is not signed with the wrong history.

Reading: After a non-updating comment snapshot settles, useComment still reconciles late-arriving canonical fields—number, postNumber, and author.shortAddress—into the frozen object while ignoring later live changes to content, votes, and reply counts.

README/LLM docs add examples for partial author overrides and frozen-update behavior; regression tests cover both paths.

📝 Walkthrough

Walkthrough

The PR updates useComment to reconcile canonical publication metadata after freezing and updates publishComment to preserve account author identity during partial overrides. Tests and documentation describe both behaviors, with changelog references updated.

Changes

Published comment consistency

Layer / File(s) Summary
Comment metadata reconciliation
src/hooks/comments.ts, src/hooks/comments.test.ts, README.md, llms-full.txt
useComment absorbs canonical comment number, post number, and author short address after a settled non-updating snapshot. The test validates this behavior. Documentation describes the frozen update behavior.

publishComment merges partial author overrides with the account author. Tests verify address preservation. Examples and changelog references document the behavior and release entry.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to f99fc

The change can still copy updated votes or replies into supposedly frozen comment views and can carry a previous comment reference across an author identity change, leading to stale or invalid comment data. These are bounded correctness issues in the current implementation, so merge should wait for the fixes.

P2 Badge Merge only reconciled metadata into the frozen snapshot

When an autoUpdate: false snapshot settles before its canonical number, postNumber, or shortAddress arrives, this replaces the entire frozen comment with the latest store object. If that same update also contains newer mutable fields such as upvoteCount, replyCount, or content, those live changes leak into the supposedly frozen result, contrary to the documented behavior. Preserve the existing snapshot and merge only the three canonical metadata fields.

Addressed the valid review finding in bfac03d8: settled non-updating snapshots now merge only canonical publication numbers and the short author address, while mutable content and vote fields remain frozen. The focused 59-test comments suite, build, lint, and type-check pass locally.

Addressed the remaining valid CodeRabbit findings in 68013dc4:

  • the frozen-comment regression now settles number, postNumber, and author.shortAddress independently while proving content, votes, and replies remain frozen after each update;
  • partial same-author overrides preserve previousCommentCid, while a different author-address override no longer inherits the active account's comment chain.

The full unit suite passes (1,225 passed, 6 skipped), as do build and type-check. Lint reports zero errors and the same 194 pre-existing warnings.

The generated 0.1.42 changelog text in llms*.txt is intentionally retained: repository policy requires running yarn llms:generate after README changes, and that generation synchronizes the already-released changelog from master.
