Self-service account deletion with a 6-month soft-delete retention window and an automatic bounded purge:
Dashboard danger zone: labeled confirmation checkbox + "Delete my account". One transaction sets users.deletedAt, destroys every session (immediate global sign-out), and deactivates the user's channels — moderation stops at once.
Sign-in restores: authenticating within the retention window clears deletedAt in the login callback. Channels stay active=0 until the user re-enables them — moderation never resumes silently.
Cron purge (I10/I8): each cron invocation purges ONE user whose 6-month retention expired — sessions, channels, and their rules/comments/moderation actions/audit rows are deleted explicitly (no FK cascades on channel-scoped tables). Skipped entirely under DRY_RUN=true.
The consent log survives (LGPD Art. 16): the users row is anonymized to a tombstone (deleted:<id>, [deleted]) rather than deleted, keeping consents.userId valid and the evidentiary chain intact (doc version, exact checkbox text, IP, user agent). The tombstone also frees the real Google sub for a future fresh signup.
Migration
0008 adds nullable users.deleted_at (I7 expand-migrate-contract). After merge: run npm run db:migrate from the main checkout AND verify the column exists — per the 0007 incident, drizzle-kit can exit 0 without applying when Turso is unreachable; AGENTS.md now documents this verification step.
Notes
Coordination: the privacy policy's retention wording is owned by the legal-pages work — if it's updated materially, LEGAL_VERSION must be bumped (the re-consent flow from feat: post-OAuth consent interstitial with evidentiary consent log #36 already handles routing). Not changed here.
Out of scope: Google token revocation on deletion (channel deactivation already stops all API use), admin-initiated deletion.

CodeAnt-AI Description
Add self-service account deletion with a six-month recovery window and permanent cleanup
What Changed
Users can delete their account from the dashboard after confirming, which signs them out everywhere and immediately stops channel moderation.
Signing in again within six months cancels the deletion; channels remain inactive until the user re-enables them.
Scheduled cleanup permanently removes expired account data while retaining anonymized consent records for compliance.
Cleanup processes one expired account per run and makes no changes during dry runs.
Impact
✅ Immediate global sign-out after deletion ✅ No moderation from deleted accounts ✅ Recoverable accounts for six months ✅ Consent records retained for compliance

Bonobo791/Moderaty#25: Extends the shared user, session, dashboard, OAuth, consent, and retention model.
2. Async purge queue (worker) instead of bounded cron purge
➕ Purges can run to completion without cron time budgeting concerns
➕ Easier to batch multiple users during low traffic
➖ Requires queue/worker infrastructure and operational complexity
➖ More moving parts vs the current one-user-per-invocation bound
3. Separate PII table + delete PII row on purge
➕ Cleaner compliance story: keep user identity vs PII clearly separated
➕ Avoids tombstoning fields in the primary users table
➖ Schema refactor and wider code churn (joins, auth lookup, uniqueness on google_sub)
➖ More migration complexity than necessary for current goals
Recommendation: The PR’s approach is a good fit: soft-delete + immediate session revocation/channel deactivation minimizes risk, and the bounded cron purge respects runtime limits. Tombstoning (instead of deleting) is a pragmatic way to preserve consents.userId without reworking the consent schema. The main alternatives (FK cascades, worker queue, or PII table split) add significant schema/ops complexity relative to the current requirements.

Summary
This PR implements account deletion with soft-delete and 6-month retention. The implementation is generally sound with comprehensive test coverage (238/238 tests passing). However, I've identified 4 critical defects that must be addressed before merge:
Critical Issues Found
Race condition in account restoration - Users can restore accounts after the 6-month retention period has expired if they sign in after the cutoff but before the cron purge runs
Transaction rollback handling - The deleteAccount transaction could leave inconsistent state if operations fail partway through
Error handling in purge - The cron endpoint may return success even if purge fails, masking data integrity issues
Empty array handling - The purge logic may crash when processing users with no channels, depending on ORM behavior with empty arrays
Security & Compliance
The implementation correctly preserves consent records per LGPD requirements and uses proper soft-delete with tombstone anonymization. The 6-month retention window is appropriate for data protection compliance.
Next Steps
Address the 4 critical findings above, particularly the race condition in restoration logic and empty array handling, before merging. Consider adding test coverage for edge cases like restoring after retention expiry and purging users with no channels.
You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.

🛑 Crash Risk: The transaction marks deletedAt and deactivates channels, but if session deletion fails mid-transaction, the user might retain an active session with a "deleted" account status. This could allow continued API access until session expiry despite account deletion. The transaction will rollback on failure, but error handling should explicitly verify all operations succeeded.
The reason will be displayed to describe this comment to others. Learn more.
🛑 Data Integrity Risk: The purge function performs cascading deletes across multiple tables outside a transaction scope. If the database operation fails partway through (e.g., between deleting comments and rules), the user's data will be partially deleted, leaving orphaned records. The inner transaction at line 58 protects the purge logic, but wrapping the purgeExpiredUser() call itself in error handling would prevent returning a success response if purge fails.
1. Purge reselects same user⊘ Outdated🐞 Bug≡ Correctness
Description
purgeExpiredUser() anonymizes the user but leaves users.deletedAt unchanged, so the same (oldest)
user remains eligible and can be selected every cron invocation, starving other expired users
indefinitely. This breaks the “one expired user per invocation” bounded drain behavior.
Likely real logic bug: without updating deletedAt, cron can keep selecting the same expired user
repeatedly.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The selection criteria is only based on deletedAt, and the purge transaction never updates that
field, so the row stays eligible and (being the oldest) can be selected repeatedly.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
`purgeExpiredUser()` selects users purely by `deletedAt` being non-null and older than the cutoff, but the purge transaction does not change `deletedAt`. After the first purge, that same user stays eligible forever and will likely be re-selected every run (because it is still the oldest), preventing any other expired users from being purged.
## Issue Context
The purge currently tombstones by rewriting `googleSub/email/displayName` only. A purged/tombstoned user should not remain in the “expired but pending purge” queue.
## Fix Focus Areas
- src/routes/api/cron/+server.ts[48-74]
## Suggested fix
- In the purge transaction, also transition the row out of eligibility, e.g.:
- set `deletedAt` to `null` (or introduce a new `purgedAt` / `tombstonedAt` column), OR
- adjust the selection predicate to exclude already-tombstoned rows (e.g. `google_sub NOT LIKE 'deleted:%'`) and set that marker atomically.
- Consider making the “claim” atomic (update-returning) so concurrent cron invocations can’t select the same user.

2. Expired deletions can restore✓ Resolved🐞 Bug≡ Correctness
Description
The Google login callback clears deletedAt for any soft-deleted user without checking whether the
deletion is still within the retention cutoff. If cron hasn’t purged yet, a user can sign in after
the retention window and permanently prevent/undo the intended purge.
+ // Signing back in within the 6-month retention window cancels a pending+ // deletion. Channels stay inactive (active=0 from the deletion) until the+ // user re-enables them — moderation never resumes silently.+ if (user.deletedAt) {+ await db.update(users).set({ deletedAt: null }).where(eq(users.id, user.id));+ console.info(`account ${user.id} restored by sign-in; pending deletion cancelled`);

●●● Strong
Matches PR intent (“within retention window”); missing cutoff check is a concrete correctness bug.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
Cron defines a retention cutoff and only purges after it, but the login callback clears deletedAt
whenever it is set, with no cutoff check, allowing post-retention restoration before cron runs.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
The login callback unconditionally restores any `user.deletedAt` by setting it to null. This violates the documented behavior that restoration is only allowed within the retention window; it also allows “expired but not yet purged” accounts to be brought back.
## Issue Context
Cron’s retention logic is `cutoff = now - RETENTION_MS` and purges when `deletedAt < cutoff`. The login callback needs to enforce the same cutoff semantics to avoid restoring beyond retention.
## Fix Focus Areas
- src/routes/api/auth/google/login/callback/+server.ts[82-104]
- src/routes/api/cron/+server.ts[30-56]
## Suggested fix
- Compute the same cutoff in the login callback and only clear `deletedAt` when `deletedAt` is within the retention window.
- If `deletedAt` is older than the cutoff, do NOT restore; instead tombstone/purge immediately (freeing `googleSub`) and continue the flow as a fresh signup (park pending consent and redirect to `/consent?state=...`), or surface a user-friendly “account permanently deleted” flow that also frees `googleSub`.
- Prefer extracting a shared helper (e.g. `retentionCutoffIso()` / `isWithinRetention(deletedAt)`) to keep cron + login consistent.

3. No deleted_at purge index✓ Resolved🐞 Bug➹ Performance
Description
The purge query filters/orders by users.deletedAt, but the migration only adds the column without an
index, so the cron purge will tend to degrade to a scan as the users table grows. This can increase
cron latency and reduce reliability under load.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The migration shows only a column add, while cron’s purge query filters and orders on that column;
indexing is needed for scalable selection of the oldest expired deletion.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
`purgeExpiredUser()` queries `users` by `deletedAt` (non-null and < cutoff) and orders by `deletedAt` with `LIMIT 1`. Without an index, this will not scale well as user rows grow.
## Issue Context
Migration 0008 adds `users.deleted_at` but does not create an index.
## Fix Focus Areas
- drizzle/0008_aromatic_red_wolf.sql[19-19]
- src/routes/api/cron/+server.ts[48-56]
- src/lib/server/db/schema.ts[22-33]
## Suggested fix
- Add a new migration (preferred) that creates an index, e.g. `CREATE INDEX users_deleted_at_idx ON users(deleted_at);`.
- Declare the same index in Drizzle schema (`sqliteTable(..., (t)=>[ index('users_deleted_at_idx').on(t.deletedAt) ])`) so drift is pinned.

RETENTION_MS is implemented as a fixed 180 days, which may not match the documented “6-month
retention” policy if “month” is intended to mean calendar months. This can purge a few days
earlier/later than expected depending on month lengths.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
Retention is described as “6-month retention” in docs, but the implementation uses a fixed 180-day interval. If legal/product intent is calendar months, this can drift.
## Issue Context
This is only an issue if retention must be calculated by calendar months rather than an approximate day count.
## Fix Focus Areas
- src/routes/api/cron/+server.ts[28-31]
- AGENTS.md[178-186]
## Suggested fix
- If calendar semantics are required, compute cutoff via month arithmetic, e.g. `const cutoffDate = new Date(); cutoffDate.setMonth(cutoffDate.getMonth() - 6); const cutoff = cutoffDate.toISOString();`, and use that in both cron purge and sign-in restore gating.

5. deletedAt used without migration guard 📘 Rule violation≡ Correctness
Description
The PR adds the users.deleted_at column and immediately reads/writes it in request handlers
without a runtime guard or a deployment guarantee that migrations ran first. If the app is deployed
before db:migrate is applied, these code paths can fail at runtime with missing-column database
errors.

● Weak
Very similar migration-guard suggestion was explicitly rejected for new DB object reads in login
callback.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The checklist requires guarding reads of newly added DB columns unless migrations are guaranteed to
run before serving traffic. This PR adds deleted_at via migration and then uses user.deletedAt /
users.deletedAt in handlers, which will break if the migration hasn’t been applied yet.
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
A new DB column (`users.deleted_at`) is introduced and then used in production handlers, but there is no safeguard for deployments where the migration has not yet been applied. This can cause runtime failures (missing column) during login, cron, or account deletion.
## Issue Context
The migration adds `deleted_at` as a nullable column, but Turso/SQLite will still error if queries reference a column that does not exist yet. The compliance requirement expects either a guaranteed “migrate-before-serve” deployment unit or a defensive runtime fallback.

CodeAnt-AI Description
Add self-service account deletion with a six-month recovery window and permanent cleanup
What Changed
Users can delete their account from the dashboard after confirming; they are signed out everywhere and all connected channels stop moderating immediately.
Signing in within six months cancels the deletion, while keeping channels inactive until the user manually re-enables them.
Sign-ins after six months and scheduled cleanup permanently remove account data, while retaining an anonymized user record and legal consent history.
Scheduled cleanup processes the oldest expired account one at a time, skips changes in dry-run mode, and reports which account was purged.
Expired-account lookups now use a dedicated index, with tests covering deletion, restoration, cleanup, retention boundaries, and dry runs.
Impact
✅ Immediate global sign-out after account deletion ✅ No moderation resumes without manual re-enablement ✅ Consent records remain available after personal data removal

A concurrent login can recreate a valid session after account deletion signs the user out
Deleting existing sessions is not atomic with preventing new session creation. A Google login callback can read the user before this transaction, then create a session after this transaction deletes all sessions; session resolution does not check users.deletedAt, so that newly created session gives access to an account that was already deleted. Serialize deletion with login/session creation or make session creation conditional on the user still being active.
❌ Deleted users can regain an authenticated session.

Deactivation does not cancel an already-claimed moderation run
The active = 0 update does not stop a cron run that already passed its active check and claimed this channel. That run can continue calling YouTube and insert comments, moderation actions, and audit rows after deletion commits, so account deletion does not guarantee immediate moderation shutdown. Coordinate the claim/run lifecycle with deletion or re-check ownership and active state before every external action and write.
❌ Deleted channels may receive new moderation records.
⚠️ Immediate global moderation shutdown is not guaranteed.

Logic error
Account deletion is cancelled before the user completes the required consent flow
Clearing deletedAt before checking current consent permanently cancels the deletion as soon as Google authentication succeeds. If the account has stale or missing consent, the callback redirects to /consent; abandoning that flow leaves the account restored and prevents the retention purge. Restore the account only after the consent flow completes successfully, or otherwise preserve the pending-deletion state.
❌ Abandoned consent leaves the deleted account retained indefinitely.
⚠️ Retention purge no longer selects that account.

A retention purge failure aborts the entire cron invocation before moderation runs
The retention purge runs outside the channel-processing error boundary, so any database or transaction failure from purgeExpiredUser() rejects the cron request before a channel is selected or claimed. This makes a purge outage stop scheduled moderation for that invocation and returns no structured purge failure. Isolate purge failure from channel execution, or catch and report it while continuing with the channel work.
❌ Cron invocation skips its selected moderation channel.

Deactivation during enforcement still allows later moderation actions and state writes to complete
The second check only validates the channel before entering processOutstandingActions; that function then claims and processes multiple batches with YouTube calls and database updates. Deletion can commit immediately after this check, so later batches can still moderate comments and persistResults can update channel state after the account has been deleted. Re-check or enforce the active condition at each batch/write boundary.

An unconditional restore can overwrite a concurrent account deletion and recreate access after sign-out
The restore update is not conditional on the deletedAt value that was read earlier. If account deletion commits after the callback reads the user but before this update, this statement clears the newly-created deletion marker and the callback then creates a valid session, defeating deletion's immediate global sign-out and allowing the deleted account back in.

Performance
An unbounded purge can consume the entire cron budget and prevent the scheduled channel run
The purge runs synchronously before channel selection but is not given the handler deadline. Although only one user is selected, deleting all of that user's channels and every channel-scoped child row can take longer than the 20-second budget; the subsequent runChannel then starts with an expired deadline and scheduled moderation is skipped or fails. Bound the purge work or reserve/enforce time for channel processing.
⚠️ Large retained accounts delay scheduled moderation.

A stale pre-transaction user read can create a session for an anonymized tombstone
The user is read before the transaction, so a concurrent purge can anonymize this row after the read but before the transaction starts. The transaction then inserts a consent and creates a session for the tombstone; because the stale deletedAt value is used, the conditional update is skipped and the anonymized account becomes authenticated. Re-read and validate the account inside the transaction, or use a conditional update that verifies the expected non-tombstone state before creating the session.

Self-service account deletion with a 6-month soft-delete retention window and an automatic bounded purge:
Dashboard danger zone: labeled confirmation checkbox + "Delete my account". One transaction sets users.deletedAt, destroys every session (immediate global sign-out), and deactivates the user's channels — moderation stops at once.
Sign-in restores: authenticating within the retention window clears deletedAt in the login callback. Channels stay active=0 until the user re-enables them — moderation never resumes silently.
Cron purge (I10/I8): each cron invocation purges ONE user whose 6-month retention expired — sessions, channels, and their rules/comments/moderation actions/audit rows are deleted explicitly (no FK cascades on channel-scoped tables). Skipped entirely under DRY_RUN=true.
The consent log survives (LGPD Art. 16): the users row is anonymized to a tombstone (deleted:<id>, [deleted]) rather than deleted, keeping consents.userId valid and the evidentiary chain intact (doc version, exact checkbox text, IP, user agent). The tombstone also frees the real Google sub for a future fresh signup.
Migration
0008 adds nullable users.deleted_at (I7 expand-migrate-contract). After merge: run npm run db:migrate from the main checkout AND verify the column exists — per the 0007 incident, drizzle-kit can exit 0 without applying when Turso is unreachable; AGENTS.md now documents this verification step.
Notes
Coordination: the privacy policy's retention wording is owned by the legal-pages work — if it's updated materially, LEGAL_VERSION must be bumped (the re-consent flow from feat: post-OAuth consent interstitial with evidentiary consent log #36 already handles routing). Not changed here.
Out of scope: Google token revocation on deletion (channel deactivation already stops all API use), admin-initiated deletion.
Verification
npm run test: 238/238 (incl. 3 new deleteAccount tests, sign-in restore test, 4 purge tests covering consent-log retention, retention-window exclusion, one-per-invocation bound, and DRY_RUN)

CodeAnt-AI Description
Add self-service account deletion with safe six-month retention and purge handling
What Changed
Users can confirm account deletion from the dashboard; they are signed out everywhere and all channels stop moderating immediately.
Deleted accounts can be restored by signing in within six months, while channels remain inactive until manually re-enabled.
Accounts past the retention window are purged automatically or during sign-in; owned sessions, channels, moderation data, and audit records are removed while consent records remain in an anonymized account record.
Scheduled cleanup processes one expired account at a time, skips cleanup in dry-run mode, reports cleanup failures, and continues channel moderation.
In-progress moderation stops before saving new work or applying YouTube actions when account deletion deactivates a channel.
Sessions belonging to deleted accounts are rejected and removed, and retention lookups use an index for scheduled cleanup.
Impact
✅ Immediate sign-out and moderation shutdown after deletion ✅ Account recovery within the six-month retention window ✅ Consent records preserved after personal data purge

Make the refund guard policy-aware.
The loop checks only literal substrings. It can allow an unconditional promise such as Full refunds are available for unused credits. because none of RETIRED_PROMISES matches, while the separate /full refund/i assertion still passes. It can also reject compliant text such as No refund upon cancellation of your account. because the matcher ignores negation. Assert the seven-day refund scope and the post-window unused-credit denial for each surface, or use polarity-aware matching. The canonical policy is defined in src/lib/server/legal.ts:63-64.
As per coding guidelines, tests must fail when the real logic is wrong.

Add coverage for the child-table deletes, cross-user isolation, and consent preservation.
seedUser creates only a user, a channel, and a session. No test creates rows in comments, rules, audit_log, moderation_actions, or consents.
Three defects in purgeUserById pass this suite today:
Lines 70-73 of src/lib/server/retention.ts delete moderationActions, comments, auditLog, and rules. Remove any of those four statements and every test still passes.
Change eq(channels.userId, userId) on line 75 to an unscoped delete and the suite still passes. Test 4 seeds four users but asserts only users rows, never the other users' channels and sessions.
Add a tx.delete(consents) to the purge and the suite still passes. Consent preservation is the stated legal reason for the tombstone design, and it has no test.
Add consents to the setupTestDb truncation list on line 26 before adding the consent assertion.

purgeUserById performs durable deletes and an anonymizing update without checking DRY_RUN. The Google login callback calls it directly, so an expired account can be purged during a dry run even though the cron route skips purgeExpiredUser.
Read DRY_RUN through $env/dynamic/private. If the purge is skipped, do not continue the callback as a fresh signup while the existing tombstone still owns the Google identity.

Line 95 calls purgeUserById(user.id) without a try/catch. The cron endpoint catches the equivalent purge failure, logs it, and continues (src/routes/api/cron/+server.ts lines 70-75). This file has no such handling: if the purge write fails, the exception propagates uncaught out of the login callback, and the user gets no clear message — unlike every other failure branch in this function, which returns error(502, '...') with a specific reason.
Wrap the purge call and fail with the same explicit error pattern already used in this file.

Re-check the retention cutoff inside the transaction before restoring a soft-deleted account.
This branch restores a soft-deleted account (clears deletedAt) without calling isRetentionExpired, unlike src/routes/api/auth/google/login/callback/+server.ts (lines 93-97), which enforces the same cutoff before allowing a restore. If the account crosses the retention boundary between the login callback's earlier check and this action running, it gets restored here instead of purged — defeating the documented 6-month retention guarantee.
The user row is also read once, before the transaction starts, and its deletedAt value is used unchanged inside the transaction. If a concurrent cron purge anonymizes this same user in between (setting google_sub = 'deleted:<id>', wiping email/display name, clearing deletedAt), this code still inserts a consent row and creates a live session bound to the now-tombstoned identity, because it never re-reads the row inside the transaction.
Move the lookup inside the transaction and reject with isRetentionExpired, matching the callback's pattern.

What
Self-service account deletion with a 6-month soft-delete retention window and an automatic bounded purge:
users.deletedAt, destroys every session (immediate global sign-out), and deactivates the user's channels — moderation stops at once.deletedAtin the login callback. Channels stayactive=0until the user re-enables them — moderation never resumes silently.DRY_RUN=true.deleted:<id>,[deleted]) rather than deleted, keepingconsents.userIdvalid and the evidentiary chain intact (doc version, exact checkbox text, IP, user agent). The tombstone also frees the real Google sub for a future fresh signup.Migration
0008 adds nullable
users.deleted_at(I7 expand-migrate-contract). After merge: runnpm run db:migratefrom the main checkout AND verify the column exists — per the 0007 incident, drizzle-kit can exit 0 without applying when Turso is unreachable; AGENTS.md now documents this verification step.Notes
