Evidence

Evidence: demonstrated — local dev web app with local PostgreSQL at head 55bed42ed: the native code request and code exchange routes were driven over HTTP with a non-production admission sentinel and the local email outbox, and the observed results are listed under Verification.

Change

• Use dedicated persisted state for each supported native verification mode.
• Apply one wrong-guess allowance per issued code across both modes: a wrong guess is refused once the combined count reaches the allowance, and each failure is recorded against the mode it arrived in.
• Add one additive database migration for the new counter column, generated on current main at the next free index (0302), plus behavioral regression coverage.
• Preserve existing response values, compatibility support, telemetry, and the planned compatibility-removal note.

Verification

• The full migration chain applied in order to an empty database from this head, and drizzle-kit check reports a consistent journal and snapshot set; the generated DDL is a single additive column at index 0302.
• Native auth route suites on this head: 432 tests passed, including the cross-mode allowance cases (sequential mixed-mode wrong guesses, and twenty concurrent mixed-mode wrong guesses) and both settlement cases.
• HTTP against the local dev app and local PostgreSQL, one challenge row per request:
  • A code request returned a challenge identifier and wrote the code email to the local outbox.
  • Three wrong guesses with the challenge and two without each returned 401 INVALID_CODE; the persisted counters then read 3 and 2 for that code.
  • The next wrong guess returned 429 TOO_MANY_ATTEMPTS in either mode.
  • The correct code then verified with its challenge and returned access plus refresh credentials.
  • Five wrong guesses without a challenge left the challenge mode open: the correct code with its challenge verified and returned credentials.
  • Five wrong guesses with the challenge left that mode exhausted for the correct code (429 TOO_MANY_ATTEMPTS) while the code still settled through the other mode.
  • A consumed code replayed as 401 INVALID_CODE, and a code presented without a challenge settled and returned credentials.
• Web-shared package type check, targeted lint, formatting, and git diff --check: passed.

This is a nonvisual backend change. Live email delivery, production firewall configuration, and platform attestation were not exercised; development admission was used only with local fixtures.

Production prerequisites

None.

Proxy answers

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

1. Question: Policy scope: Source confirms optional-challenge compatibility is intentional, and issuance already calls the email firewall limiter. Approve the scoped plan: retain both verification modes, give each its own five-failure counter, add legacy_attempts defaulting to zero while retaining historical attempts, and leave issuance/resend policy unchanged?
   Answer: Approve scoped compatibility plan
   Confidence: 0.86 · Precedent: Autonomy: make executive decisions yourself with "is this reasonable?" as the test; the plan matches the brief, and the pull request is merge-by-human for auth and database changes.
2. Question: Inherited CI: The PR's verify job fails on two pre-existing operator-assignment lint errors in the supported browser extension, introduced on main before this branch. No upstream correction exists for that file. Approve a separate two-line changed ||= nested.changed cleanup so this PR can obtain green CI?
   Answer: Apply minimal CI cleanup
   Confidence: 0.80 · Precedent: Fix a gap or error even when it is not the current task, and a work item must converge.
3. Question: Guess budget: should the single wrong-guess allowance also cover a submission carrying the correct code, or only wrong guesses, given that a correct code must still verify when the other mode spent the allowance?
   Answer: Combined cap on wrong guesses only (Recommended)
   Confidence: 0.70 · Precedent: Keep one allowance without denying the legitimate holder or breaking shipped compatibility clients.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The follow-up commit adds the missing legacy_attempts migration at index 0302 with a matching snapshot and journal entry, resolving the previously flagged schema/migration gap; the diff contains only generated migration artifacts that match packages/db/src/schema.ts:5062.

Assumptions: [INFERENCE] The deploy pipeline runs the Drizzle migrator before promotion, as the PR description states; the additive NOT NULL DEFAULT 0 column on magic_link_tokens is metadata-only on PostgreSQL 11+ and does not rewrite the table. Migration artifacts were not executed in this read-only review; correctness was verified by comparing the SQL, snapshot delta, and journal chain against the schema.

Status: 1 Issues Found | Recommendation: Address before merge

Executive Summary

The revised shared wrong-guess allowance fixes the previously flagged split-budget issue, but the merge with main dropped the only migration for legacy_attempts, so the schema and runtime now reference a column the deploy pipeline will never create.

Assumptions: [INFERENCE] The deploy pipeline applies only the committed Drizzle migrations (as the PR description states); if legacy_attempts is created out-of-band in production the outage would not occur. The earlier in-thread WARNING about two independent per-mode allowances is resolved by the new attempts + legacy_attempts bound.

packages/db/src/schema.ts	5062	legacy_attempts is declared in the schema but no migration adds it: the branch's additive migration was dropped during the final merge with main and never regenerated. _journal.json ends at 0301_contributor_credit_window and meta/0301_snapshot.json has no legacy_attempts, while reserveSignInCode selects the full row and evaluates magic_link_tokens.legacy_attempts, so native sign-in code verification fails with "column does not exist".

Previous review (commit 4f0839e)

Status: 1 Issues Found | Recommendation: Address before merge

Executive Summary

The change's only substantive concern remains the split per-mode guess budget: one live sign-in code now carries two independent five-failure counters, so the same row admits up to ten wrong guesses; the migration renumber and snapshot regeneration are otherwise clean.

Assumptions: [INFERENCE] Issuance-side and email-firewall rate limiting were not re-read in full; the doubled per-code budget assumes those do not also cap wrong guesses per code. The per-mode counter split is described in the PR as an owner-approved policy decision, so the WARNING is carried forward for the human merge decision rather than as a new blocking finding.

Executive Summary

The sign-in code still splits one live code's five-guess budget into two independent five-guess counters, so the same row admits up to ten wrong guesses; all other changes since the prior review are a clean migration renumber and a merge from main.

Assumptions: [INFERENCE] Issuance-side rate limiting and the email firewall limiter were not re-read in full; the doubled per-code budget assumes those do not also cap wrong guesses per code. The per-mode counter split is an owner-approved policy decision per the PR, so the WARNING is carried forward for the human merge decision.

[iscekic]

Changes requested: keep one wrong-guess budget per sign-in code, and renumber the migration.

• reserveSignInCode (packages/web-shared/src/lib/auth/magic-link-tokens.ts) now gives each mode its own cap of 5. POST /api/auth/native/otp returns the challenge id to the requester, so one caller can make 5 guesses with it and 5 without it. That is 10 guesses per issued code instead of 5.
• Keep both counters, but also reject a reservation when attempts + legacy_attempts >= 5. Apply this in the pre-check and in the reservation guard.
• Restore a test equivalent to the removed R6: guesses across both modes together stop at 5 for one code.
• fix(kilo-mcp): require the confirmed client for a device pairing #8534 is in the merge queue with migration 0300. After it lands, merge main and regenerate this migration at the next free number.
• Fix the PR body's production prerequisites section so that it reads exactly None. if no manual step is needed.

[iscekic]

Changes requested: renumber the migration again. It collides with main.

• main now has 0301_contributor_credit_window (from fix(contributor-champions): apply the credit window to enrollment and tier changes #8701). This branch adds 0301_conscious_taskmaster, so it conflicts in packages/db/src/migrations/meta/0301_snapshot.json and meta/_journal.json.
• Merge the latest main, take main's journal and snapshots, and regenerate this migration at the next free number after main's latest migration (currently 0302).
• Three open PRs (cli-sessions: share and fork storage rules #8224, fix(reviews): share monitor evaluation results #8664, fix(auth): maintain native verification state #8845) need a new migration. Only one of them can use 0302. If another one merges first, merge main again and regenerate this migration again.
• Re-run the migration chain on an empty database and the drizzle check on the merged tree.

[iscekic]

bot: Applied in 571a0d11c.

• One wrong-guess allowance per issued code across both modes: a wrong guess is refused once the combined counted failures reach the allowance, checked before the code comparison resolves and again in the increment guard. Each failure is still recorded against the mode it arrived in, so both counters stay meaningful.
• The correct code is accepted unless the mode it arrives in has itself spent the allowance, so one mode cannot deny the holder through the other.
• Restored the cross-mode test: three wrong guesses with a challenge plus two without stop the next wrong guess in either mode at the allowance, with counters 3 and 2, and the correct code still settles. A concurrent mixed-mode test covers the same property under a race (five counted, the rest refused).
• Migration regenerated at the next free index; see the renumber reply.

[iscekic]

bot: Renumbered in 24f377b9f.

• Merged current main, kept main's journal and snapshots, and regenerated this branch's additive migration at 0302 (0302_harsh_silhouette.sql); the earlier branch migration file and its metadata are gone.
• Applied the full migration chain in order from an empty database, and drizzle-kit check reports a consistent journal and snapshot set. The generated DDL is one additive column.
• If another pull request takes 0302 first, I will merge main again and regenerate at the next free index.

[iscekic]

bot: Correction to the renumber reply's commit reference: the migration file, its snapshot, and the journal entry landed in 55bed42ed, after the merge commit. The functional change is in 571a0d11c. Verification in the body ran at 55bed42ed.
