Evidence

Evidence: demonstrated — local database-backed regression suites and the running development web app exercised native sign-in code issuance, verification, credential settlement, and refusal responses at 305f92120b97f67947444068a382a21701eedede with owned fake accounts, local PostgreSQL, the local email outbox, and development admission.

Change

Persist native verification state with the approved compatibility contract and existing response values and telemetry. Include behavioral regression coverage and one generated additive migration.

This follow-up merges current main, resolves the migration-index collision by regenerating this branch's migration as 0309_ancient_sauron.sql with matching snapshot and journal metadata after main's newest entries, and keeps the application implementation unchanged. The generated SQL adds one column. After the merge, the branch differs from main only in this migration and the sign-in code verification accounting with its tests.

Verification

• pnpm install --frozen-lockfile — passed.
• pnpm drizzle check and the migration journal test — passed, with an existing timestamp-order warning for historical entries 0034 and 0035.
• pnpm drizzle migrate — the full chain applied from an empty database: 310 journal entries recorded, the table reports the new integer column with default 0 and NOT NULL, and the newest main indexes exist.
• Targeted database-backed Jest run for magic-link-tokens.test.ts, native token route, and native OTP route at this head — 3 suites, 158 tests passed.
• HTTP proof at this head against the running development app, owned fake accounts, issuance captured in the local email outbox, development admission sentinel:
  • five wrong compatibility guesses were refused as wrong codes, and the challenge-bound correct code still settled with a credential pair;
  • with the allowance spent by compatibility guesses, a further wrong guess in the other mode returned 429 TOO_MANY_ATTEMPTS, while the challenge-bound correct code still settled;
  • replaying a consumed code returned 401 INVALID_CODE;
  • five wrong challenge-bound guesses were refused, and the next verification returned 429 TOO_MANY_ATTEMPTS;
  • a compatibility caller settled a live code by email.
• Persisted state after that run: rows with five compatibility guesses recorded legacy_attempts = 5, attempts = 0; rows with five challenge-bound guesses recorded attempts = 5, legacy_attempts = 0; settled rows were consumed. All 8 assertions passed.
• git diff --check — passed. Generated migration metadata follows the repository formatter exclusion.

This is a nonvisual backend change. No screenshot is applicable. Live email delivery, production firewall configuration, and platform attestation were not exercised.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental commit replaces a stale storage-key test with boundary coverage of the 64-byte message cursor id limit, which now matches the fitsKiloSdkMessagesCursorId rule already applied on main.

Assumptions: [INFERENCE] Test behavior was verified by reading the schema and contract rather than executing the suite. msg_ + 60 characters is exactly 64 bytes and msg_ + 62 is 66 bytes, so the accepted/rejected pair correctly brackets MAX_KILO_SDK_MESSAGES_CURSOR_ID_BYTES (packages/session-ingest-contracts/src/rpc-contract.ts:1021). The previous migration finding is resolved: 0307_misty_grim_reaper.sql, its snapshot, and the journal entry at idx 307 are present and chain from 0306. The prior per-mode attempt-budget comment is addressed at magic-link-tokens.ts:210 and :247, where wrong guesses are bounded by attempts + legacy_attempts.

Previous review (commit cd2d9d4)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change only renumbers the additive legacy_attempts migration to 0307_misty_grim_reaper on top of main's migrations through 0306; the SQL is byte-identical to the previously reviewed file, the snapshot prevId chains to 0306's id, the journal has a unique idx 307 entry matching the tag, and the schema delta remains the single additive column.

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 populated table. Migration artifacts were not executed in this read-only review; consistency was verified by comparing the SQL, the 0307 snapshot's prevId chain to 0306's id, the 238-table parity between the 0306 and 0307 snapshots with only legacy_attempts added, and the single journal entry at idx 307. The native auth implementation is unchanged since the previous review; a targeted re-check at magic-link-tokens.ts:210 and :247 confirms wrong guesses are bounded by the combined attempts + legacy_attempts allowance while the correct code remains settleable in whichever mode still has budget, so the earlier split-budget concern is resolved.

Previous review (commit 66bd1f2)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change only renumbers the additive legacy_attempts migration to 0303_native_code_state on top of current main; the SQL, snapshot delta, and journal chain stay consistent with packages/db/src/schema.ts:5062, and the previously flagged missing-migration and single-allowance concerns are resolved in the current code.

Assumptions: [INFERENCE] The deploy pipeline runs the Drizzle migrator before promotion, as the PR description states; the additive NOT NULL DEFAULT 0 column on the populated magic_link_tokens table is metadata-only on PostgreSQL 11+ and does not rewrite the table. Migration artifacts were not executed in this read-only review; consistency was verified by comparing the SQL, the 0303 snapshot's prevId chain to 0302's id, the presence of only the new column, and the single journal entry at idx 303. The remaining inline WARNING about a split guess budget describes behavior the current code does not have, since magic-link-tokens.ts:210 and :247 reject wrong guesses once attempts + legacy_attempts reaches the allowance.

Previous review (commit 571a0d1)

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.

CRITICAL

File	Line	Issue
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". Regenerate on current main at index 0302 with SQL, snapshot, and journal.

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.

[iscekic]

bot: Merged origin/main into the branch in 305f9212, without rebasing, and resolved the conflicts by keeping main's content and re-applying this branch's migration on top of it.

• main's newest migration index is 0308; this branch's additive migration sits at the next free index, 0309, with its snapshot and journal entry, so the journal set is consistent.
• The branch diff against main is limited to the migration, the schema column, and the sign-in code verification accounting with its tests.
• git merge-tree --write-tree HEAD origin/main is clean at the current head, and GitHub reports the pull request mergeable and clean.
• The affected checks were rerun on the merged head: CI is 81 passed, 0 failed, including the shards that failed on the earlier head. The database-backed sign-in code suites pass at this head.
• The verification evidence in the pull request body refers to this head.
