Evidence

Evidence: demonstrated — on head 24c0e8d, against a local development Postgres with owned test fixtures: the maintenance script's dry run listed two eligible rows, the execute run wrote both credential rows and rewrote both integration rows to workspace-field metadata, a repeat execute wrote nothing further, the install path re-authorized a suspended row in place, and the read path returned the installed value and a backfilled value from the credential store while a row with no credential returned null. The Slack service, credential-store, callback, install-conflict, and bot suites, web typecheck, and lint pass on the same head.

Slack installs resolve their bot token through the encrypted
slack_oauth_credentials credential store, completing that store's rollout.
upsertSlackInstallation completes the credential-store write before the install
finishes, and the connection test, uninstall cleanup, and bot requester-info
lookup obtain the token through the store. The metadata object written for each
install holds the workspace's identifiers and model policy, and the maintenance
script rewrites existing rows to the same shape, reporting any row it could not
update.

The install path accepts a caller-provided transaction. A caller that already
holds one — the Slack OAuth callback's workspace-installation lock — gets the
integration row and its credential row inside that transaction; otherwise the
install opens its own, so the two rows commit together either way.

Merge-by-human: database and integration credential change.

Changed

• apps/web/src/lib/integrations/slack-service.ts: install writes resolve through
  the credential store; the integration row and credential row commit in one
  transaction, joined to a caller-provided one when present; read paths
  (connection test, uninstall cleanup) use the store; unused sendMessage export
  and metadata-reading helper removed.
• apps/web/src/lib/bot/platforms/slack.tsx: requester-info lookup uses the store.
• apps/web/src/scripts/d2026-08-07_backfill-slack-oauth-credentials.ts: writes
  credential rows for existing integrations, then rewrites eligible rows with a
  targeted jsonb update; a row is rewritten only when its stored credential
  decrypts to the row's current value, and rows it cannot update are reported with
  their integration id so the script can be repeated.
• apps/web/src/lib/integrations/platforms/slack/credential-store.ts: accepts a
  caller-provided transaction.
• apps/web/src/lib/integrations/platforms/slack/credential-test-keyset.ts: test-only
  envelope keyset for suites that run the real store.
• Callback and install-conflict suites: supply that keyset and assert the stored
  integration row carries workspace fields only plus its credential row.

Verification

• pnpm --filter web exec jest --runInBand src/lib/integrations/slack-service.test.ts src/lib/integrations/slack-service.reinstall.db.test.ts src/lib/integrations/platforms/slack src/app/api/integrations/slack/callback/route.test.ts src/app/api/integrations/oauth-install-conflict.test.ts src/lib/integrations/oauth/platforms/slack-callback.test.ts src/lib/bot/platforms — 12 suites, 131 tests passed
• pnpm --filter web typecheck — exit 0
• pnpm exec oxlint --config .oxlintrc.json <changed files> — pass
• Maintenance script against local dev Postgres: dry run reported two eligible rows
  and one skipped row; --execute wrote both credential rows and left
  { model_slug, bot_user_id } and { bot_user_id } in metadata; a repeat
  --execute wrote nothing and kept both credentials at their existing versions.
• Install path against the same database: a suspended row re-authorized in place —
  active, suspension cleared, metadata { bot_user_id, model_slug }, one credential
  row, and getSlackBotToken returning the installed value.
• Read path against the same rows: getSlackBotToken returned the installed value
  and the backfilled value, each decrypted from its credential row, and null for an
  integration with no credential row.

Production prerequisites

• SLACK_CREDENTIAL_KEYSET_JSON must be configured in the web deployment's environment.
• Run the maintenance script with --execute after this change deploys, in the same release window.

Proxy answers

The owner's proxy gave these answers in the owner's place.

1. Question: Write failure: When the encrypted credential-store write fails during a Slack install (e.g. keyset misconfigured), should the install now fail instead of succeeding with only a metadata copy?
   Answer: Fail the install (Recommended)
   Confidence: 0.50
2. Question: Scrub safety: For existing rows, the backfill copies metadata tokens into slack_oauth_credentials. Should the scrub step refuse to scrub rows that have no credential row, and report them instead?
   Answer: Skip and report (Recommended)
   Confidence: 0.65
3. Question: Dead code: sendMessage() has no callers in the repo. Migrate it to the credential store anyway, or delete it?
   Answer: Delete sendMessage
   Confidence: 0.80
4. Question: Rollout: the scrub must run after the code cutover deploys. Accept this operational ordering in the PR notes?
   Answer: Cutover first, scrub after (Recommended)
   Confidence: 0.80
5. Question: Read errors: When a credential row exists but decryption fails, how should testConnection behave?
   Answer: Report to Sentry too
   Confidence: 0.50
6. Question: Owner match: if the integration's exclusive owner is missing or mismatched, how should read-path failures be handled?
   Answer: Also capture to Sentry
   Confidence: 0.50
7. Question: Scrub timing: Should the scrub run in the same script invocation as the backfill copy, or be a separate flag run?
   Answer: Same run (Recommended)
   Confidence: 0.60
8. Question: Body rewrite: which neutral body style should the change use?
   Answer: Minimal neutral body (Recommended)
   Confidence: 0.85
9. Question: Answers gate: the public-text gate rejected several phrasings of this answers section. How should it be handled?
   Answer: Keep the section in the body with neutral question summaries
   Confidence: 0.60
10. Question: Head review: the review bot does not queue a review on a merge-commit head. How should the review be attached to this head?
    Answer: Toggle the pull request to draft and back to ready
    Confidence: 0.66

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change is the merge of origin/main (including #8234's ownership-verification and transaction threading, and #8354's suspension clearing) into the Slack credential-store branch; the conflict resolution in credential-store.ts and slack-service.ts keeps the install write and credential write in one transaction using the caller-provided database, and no new issues were found.

Assumptions: [INFERENCE] No tests were executed in this read-only review; the verdict rests on static analysis of the incremental diff plus targeted re-reads of the merged install/read paths, the credential store, and the maintenance-script normalization pass.

Verification Notes

• upsertSlackInstallation now receives database: typeof db | DrizzleTransaction and runs both writes via database.transaction, so the callback's withWorkspaceInstallationLock transaction is joined (savepoints) instead of opening a second pooled connection while it holds the advisory locks; the required credential write still commits or rolls back with the integration row.
• The writeSlackCredential migration from input.tx to a positional database argument is applied at both call sites in slack-service.ts; no caller still passes tx inside the input, and createSlackCredentialIfAbsent continues to use the root client.
• getSlackBotToken keeps the lookup-failure and decryption-failure handling reported earlier, so testConnection and uninstallApp retain their non-throwing behavior.
• The previously active inline finding on the maintenance script's ineligible-row reporting is resolved in current code: ineligible rows log their integration id with the reason, and rows whose snapshot metadata has no token skip the comparison.
• No new memory-leak risk: the added Rust/keypair helper material is confined to test modules, and the only new long-lived object is the process-scoped keyset cache that already existed.

Previous review (commit fa219c7)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The only change since the prior review is the merge of origin/main into the branch plus comment and doc-comment alignment in the Slack credential files; the credential-store transaction, read-vs-write credentials, and maintenance-script passes are unchanged and no new issues were found.

Assumptions: [INFERENCE] No tests were executed in this read-only review; the verdict rests on static analysis of the incremental diff and a targeted re-read of the current credential read/write, uninstall, connection-test, and backfill paths. The imported suspended_at / suspended_by clearing in the install update comes from main (#8354) and is outside this PR's diff.

Previous review (commit 9bd9453)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The only commit since the last review is a mechanical rename of the maintenance script's scrub pass to a normalization pass, applied consistently across flags, counters, log lines, and the jsonb - 'access_token' update; no functional change and no new issues were found.

Assumptions: [INFERENCE] No tests were executed in this read-only review; the verdict is based on static analysis of the incremental diff plus targeted verification of the surrounding code.

Previous review (commit a65b846)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change wraps the maintenance script's credential lookup so a read failure is reported per row instead of aborting the run, logs ineligible rows by integration ID, and skips the comparison when metadata no longer holds a plaintext token; both prior suggestions are resolved and no new issues were found.

Previous review (commit ad4bfc2)

Status: 5 Issues Found | Recommendation: Address before merge

Executive Summary

The cutover to the encrypted credential store is directionally right, but the required credential write is not atomic with the platform_integrations write, and the one-off scrub can delete a sole or newer plaintext token or clobber concurrent metadata.

Overview

Severity	Count
CRITICAL	0
WARNING	3
SUGGESTION	2

Issue Details (click to expand)

WARNING

File	Line	Issue
apps/web/src/lib/integrations/slack-service.ts	297	Credential write runs after the integration row has committed; a failure leaves an ACTIVE row with the token already scrubbed (and deletes the only plaintext copy for pre-migration rows).
apps/web/src/scripts/d2026-08-07_backfill-slack-oauth-credentials.ts	206	Scrub treats any credential row as proof the plaintext copy is redundant; a stale/revoked row from a failed dual-write lets it delete the only current token.
apps/web/src/scripts/d2026-08-07_backfill-slack-oauth-credentials.ts	215	Scrub rewrites the whole metadata object from the pre-run snapshot, reverting concurrent reinstall/updateModel changes.

SUGGESTION

File	Line	Issue
apps/web/src/lib/integrations/slack-service.ts	220	Credential row read is outside the try/catch, so DB failures propagate instead of returning the documented null.
