Greptile SummaryThe PR adds an authenticated global tag-rename operation across a user's memos, with atomic batched persistence, generated API bindings, update notifications, and a Settings UI.
Confidence Score: 4/5The PR is not yet safe to merge because a successful global rename can still lose its required memo-update events during server shutdown. Rename side effects run after the RPC returns, while shutdown closes the SSE hub before waiting for API background work, allowing the worker's memo.updated broadcasts to be silently discarded. Files Needing Attention: server/router/api/v1/memo_service_rename_tag.go, server/server.go

| Filename | Overview |
|---|---|
| server/router/api/v1/memo_service_rename_tag.go | Implements authenticated tag validation and atomic transformation, but its asynchronous side-effect fix can still lose successful rename events during shutdown. |
| store/memo.go | Defines and validates the creator-scoped atomic memo-content transformation contract. |
| store/db/sqlite/memo.go | Implements bounded transactional transformation for SQLite with rollback on failures. |
| store/db/postgres/memo.go | Implements serializable, row-locked batched transformation for PostgreSQL. |
| store/db/mysql/memo.go | Implements serializable, row-locked batched transformation for MySQL. |
| web/src/components/RenameTagDialog.tsx | Adds validated rename interaction, pending/error handling, and success feedback. |
| web/src/hooks/useMemoQueries.ts | Adds the rename mutation and invalidates memo-related query caches after success. |

server/router/api/v1/memo_service_rename_tag.go (1)
61-65: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoffConsider filtering the scan to memos that carry the old tag.
The loop loads every memo of the user and runs the Markdown rename on each one. For users with many memos, most parses do nothing. The memo payload already stores the extracted tags, so a store-level filter on the tag would reduce both reads and parses.
This is an optimization only. The current behavior is correct.

content-length validation and UpdateMemo calls to prevent an error from leaving
earlier matching memos renamed while later ones remain unchanged. Prefer a
read-only validation pass over all matching memos before applying any updates,
then perform the existing payload rebuilds and updates only after validation
succeeds; preserve the current error responses and successful rename behavior.

Addressed the three data-integrity findings in 3946b87:
Validation: go test ./..., go test -race ./server/router/api/v1/..., go vet, golangci-lint (0 issues), plus focused SQLite/MySQL/PostgreSQL container tests. I intentionally did not filter solely by payload tags: the existing stale-payload regression covers imported/migrated memos whose content still has the tag while the derived payload does not. |

626-653: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winHarden the transform callback and the timing branch.
Two points make this subtest fragile.
close(transformRead)runs unconditionally inside the callback. The callback runs once today because the user owns exactly one memo. If a driver ever retries the transaction, or if the fixture gains a second memo, the second call panics on a closed channel. Usesync.Onceor a buffered send so the callback stays safe under repeated invocation.The 100 ms timer decides which assertion set applies. On a loaded machine the concurrent
UpdateMemocan exceed 100 ms even when nothing blocks it, so the run silently skipsrequire.Error(transformResult.err). The final content assertion still catches a lost update, so the test does not become wrong, only weaker. Record the chosen branch witht.Logfso a skipped assertion is visible in CI output.♻️ Proposed hardening

Inline comments:
In `@server/router/api/v1/memo_service_rename_tag.go`:
- Around line 91-98: Bound the post-commit work around the updatedMemoIDs loop
in the rename-tag handler instead of synchronously processing every memo on the
request path. Move side-effect dispatch to a background worker or otherwise
cap/batch the fan-out, while preserving error handling and ensuring large
renames do not keep the gRPC call open or generate unbounded webhook/SSE
requests.
In `@store/db/mysql/memo.go`:
- Around line 279-282: Renamed memos do not update UpdatedTs because
applyMemoUpdate receives no timestamp. In store/db/mysql/memo.go:279-282,
store/db/postgres/memo.go:264-267, and store/db/sqlite/memo.go:257-260, set one
explicit UpdatedTs value per call and pass it in each store.UpdateMemo so all
three drivers record identical timestamp semantics.
- Around line 231-289: Refactor the memo transformation loop around the
transaction and applyMemoUpdate so batches use keyset pagination on the stable
created_ts and id ordering instead of LIMIT/OFFSET, avoiding repeated scans of
earlier rows. Do not hold one transaction and FOR UPDATE locks across the entire
transformation; process batches with a transaction scope that limits lock
duration while preserving consistent ordering and all existing transform and
persistence error handling. Apply the same change to the corresponding
PostgreSQL and SQLite implementations, or document the expected worst-case memos
per creator if the current design is intentionally retained.

If server shutdown begins after the rename commits but before this worker broadcasts its updates, shutdown closes the SSE hub before waiting for background tasks, causing the successful rename's memo.updated events to be silently dropped.
