The original B1 + fix (commit 6884c10d) only touched `archive/ingest/writes.rs`. + Mirrored the same CASE-WHEN gates plus `MAX(visit_count)` / `MAX(typed_count)`. + `payload_import.rs` also had `visit_count` / `typed_count` missing + from the UPDATE clause entirely (INSERT VALUES hardcoded `1, 0`), + so Takeout URLs stayed frozen at the first import's count — fixed. + +2. **B1 `>=` tie-break clobbered title with NULL at equal timestamps** + (commit 6587865d) — `writes.rs` upsert used `excluded.last_visit_ms >= +urls.last_visit_ms` for title / hidden, which silently overwrote + captured non-NULL title with NULL whenever last_visit_ms tied. + Firefox bookmark-only URLs (last_visit_date IS NULL → 0) tripped this + on every re-import. Tightened to `>`; added `url` and `payload_hash` + and `recorded_at` to the same strict-newer gate. + +3. **`track_url_visit_bounds` widened bounds from dropped visits** + (commit 6587865d) — `ingest/mod.rs:183` called the bounds tracker + unconditionally after `insert_visit`. When INSERT OR IGNORE silently + dropped a visit (clock-corrected re-import), `urls.first_visit_ms` / + `last_visit_ms` widened from a row that was never stored, leaving + the canonical URL claiming bounds with no matching visit. Gated on + `inserted > 0`. + +4. **B3 ordinal-tiebreaker for Takeout source_visit_id** (commit b377f394) + — The B3 fix changed `source_visit_id` to `{url}:{visit_time_micros}` + for cross-path stability but lost per-record uniqueness. Multiple + Takeout records at the same URL+microsecond collided on the + `(source_profile_id, source_visit_id)` UNIQUE index. Restored the + `ordinal` parameter as a tiebreaker — Google's Takeout JSON is a + deterministic export so ordinals are stable across re-imports. + +5. **`stable_key_i64` could return negative for `i64::MIN` input** + (commit b377f394) — `.abs()` on `i64::MIN` returns `i64::MIN` (no + positive representation) and panics in debug builds. Added explicit + corner-case branch mapping `i64::MIN → i64::MAX`. Smoke test pins + non-negativity across assorted inputs. + +6. **og:image Bilibili API memory DoS** (commits cafac470 / 014db312) + — `resolve_image_url_via_api_with_base` called `response.bytes()` + then checked size, so a multi-GB hostile/MITM response OOM-killed + the worker before the 64 KiB cap could fire. Now: Content-Length + fast-path + generic `read_with_cap` streaming helper that + aborts at the cap. Refactored the helper to take `R: Read` so the + cap-exceeded and read-error branches are unit-testable without + standing up a chunked-encoding mockito server. + +7. **Browser-back stranded canGoForward** (commit b4e77f7f) — the Pop + branch of `use-route-history-nav.ts` only decremented stackIndex, + so browser-back (which bypasses the in-app `goBack` callback) left + the topbar forward chevron disabled even though forward navigation + was available. Added `expectingForwardPopRef` to distinguish + goForward-initiated Pops from external Pops; external Pops now set + `forwardAvailable=true`. + +#### Performance + +8. **Firefox first-import OR-subquery O(N×M) regression** (commit 4992769a) + — B2 fix added `OR id IN (SELECT DISTINCT place_id FROM moz_historyvisits ...)` + to Firefox URLS_SQL. On the AGENTS.md target ceiling (14.4M visits, + first import with watermarks=0), SQLite still materializes the full + DISTINCT subquery even though the first predicate matches every row. + Added `URLS_FULL_SQL` + `first_import` branch matching the Chromium + pattern at `chromium/mod.rs:383-384`. + +#### Test/doc hygiene + +9. **Watermark assertions strengthened in C2 / C5 / X3** (commit 6587865d) + — the new scenarios asserted row counts that the fingerprint partial + index satisfies whether the watermark works or not. Added direct + `profile_watermarks.last_visit_id` assertions so a watermark + regression (cross-profile bleed, lost cursor advance) fails the test + immediately instead of silently passing through the canonical-layer + dedup. + +10. **Misleading comments + unused dep** (commits 25c90253 / 6587865d) — + `writes.rs` fingerprint comment claimed "Takeout dedup relies on + fingerprints matching Chromium's"; actual Takeout flows use + different source_kind and time encoding, so this contract didn't + exist. Rewrote to describe the real per-source-profile scoping. + F2 doc comment in `dedup_scenarios_baselines.rs` still claimed the + Firefox OR fallback was missing and the test was `#[should_panic]`; + both untrue since 6884c10d. `chrono` dep declared in fixtures + `Cargo.toml` but unused — removed plus updated lib.rs doc comment. + Fixture `chrome_time_to_unix_ms` aligned with production's `.max(0)` + clamp. + +#### New regression tests added + +- **C7** (`c7_tied_last_visit_ms_does_not_overwrite_title_hidden_or_payload_hash`) +- **T6** (`t6_takeout_payload_import_url_upsert_protects_against_older_snapshot_regression`) +- **T7** (`t7_takeout_same_url_same_microsecond_records_land_as_distinct_visits`) +- **stable_key_tests** module (smoke test for non-negativity) +- **og:image** read_with_cap × 3 (under-cap success, cap-exceeded, read-error) +- **use-route-history-nav** browser-back-enables-forward +- **fixture time.rs** pre-Unix-epoch chrome time clamps to 0 + +#### Verification + +- 616 vault-core tests pass (was 609 → 616 with C7/T6/T7). +- 46 browser-history-parser tests pass (stable_key_tests added). +- 41 vault-core og_images_synth tests pass. +- 15 use-route-history-nav tests pass. +- Rust coverage 100% (35,184 instrumented lines / 1,630 functions). +- `cargo fmt --all` clean. +- `bun run check:base` green. +- Full `bun run check` fails on the same pre-existing E2E flake + documented in the prior session + (`tests/e2e/desktop-bridge.spec.ts:223` — + `apiRequestContext.post: socket hang up` on + `POST /commands/run_backup_now`). **Verified independent of these + fixes**: reverting just `writes.rs` + `ingest/mod.rs` to the + pre-fix state (b249ea78) and re-running yields the same socket + hang-up failure.

Build a **scenario library** that covers every documented edge case in + the audit, including known bugs (B1–B6) and architecturally-correct + behaviors that future refactors might silently break. +3. Build an **end-to-end test runner** that takes one scenario, drives the + real `vault-core` ingest pipeline through it, and asserts canonical-DB + truth (visit counts, URL counts, fingerprint stability, per-profile + provenance, watermark advancement, revert safety). +4. Guarantee the harness produces **zero false positives**: every failing + assertion either is a real bug in product code or a real intentional + change that needs a contract-test update. +5. Keep the harness **self-validating**: the fixture generator itself is + tested by parser round-trip (write a fixture → parse it → assert the + parser saw what the generator promised) so a generator bug cannot + pretend a product bug exists. + +### Explicit Non-Goals + +1. **No real user data** in fixtures. The user has personal browser data + on the development machine; the playbook + ([browser-support-and-adapter-playbook.md:152](../../architecture/browser-support-and-adapter-playbook.md)) + forbids copying private URLs/titles into docs or repo. The fixture + generator **must not sample from real DBs at any layer** — every URL, + title, timestamp, and ID is synthesized from a seed. +2. **No product-code bug fixes in this work block.** B1–B6 each get a + failing test that documents the bug; fixes ship in dedicated follow-up + blocks so the fix PR can point at the failing test as evidence. +3. **No view-layer cross-browser aggregation work.** That has its own + pending work block driven by the planning conversation. +4. **No performance optimization.** Harness measures memory bounds as a + contract assertion (does a 1.44M-record import stay under the agreed + RSS ceiling?) but does not optimize the ingest pipeline. +5. **No support for non-promised browsers.** Scenarios cover the families + in [browser-support-and-adapter-playbook.md](../../architecture/browser-support-and-adapter-playbook.md): + Chromium-family, Firefox-family, Safari, Takeout. Pale Moon, qutebrowser, + mobile exports are out of scope. + +--- + +## 2.

How New Bugs Get Added + +When a user reports a new dedup / loss / duplication issue: + +1. The triage step is to add a scenario to the library that reproduces + the report from a synthetic fixture. If the synthetic fixture cannot + reproduce, the report is either operator error or a real-data leak + (e.g. Chrome version-specific schema we don't generate yet) — the + audit doc gets updated to widen the fixture surface. +2. Once a failing scenario exists, the bug is in scope for a fix work + block. +3. The fix block flips the scenario from `#[should_panic]` to plain + `#[test]` and gets merged. The scenario stays in the library forever + as a regression guard. + +This means **the harness is the bug tracker for ingest correctness**. +The audit doc lists six bugs today; the harness should converge to +zero `should_panic` annotations over time. + +--- + +## 7. Acceptance for `WORK-IMPORT-TEST-HARNESS-A` + +The work block is done when: + +1. `browser-history-fixtures` crate exists, builds clean, is in the + Cargo workspace, and is included in `bun run check`. +2. All round-trip self-validation tests pass. +3. All Priority 1 scenarios are implemented and either pass (for + contract scenarios) or `#[should_panic]` with a doc comment + referencing the audit bug (for bug scenarios). +4. The work block's CHANGELOG entry lists, by name, which audit bugs + now have failing tests. +5. The audit doc gets a new section: "Bugs with failing tests" linking + each to its scenario. + +The work block **does not** require Priorities 2–6 to be complete; those +are the natural follow-up blocks once the foundation lands. But the +spec already enumerates them so future work doesn't need to re-derive +the list. + +--- + +## 8. Open Questions to Resolve During Implementation + +These are resolvable from code-reading, not user discussion, but +deserve calling out so they aren't forgotten: + +1. **Takeout time unit truth.** Does the runtime really receive Chrome + epoch microseconds in `time_usec`, or Unix epoch microseconds, or + both depending on file format? Resolve by writing scenario T5 with + both shapes, observing which one matches the visible Chrome history + ground truth. +2. **`profile_key` collision under same-name profiles.** If a user has + two Chrome profiles both named `Default` on the same machine (e.g. + two macOS user accounts share-mounted), do they collide? Test as + scenario R6 (added if probe shows this is a real risk). +3. **Are Atlas / Comet adapters fully covered by the chromium + scenarios?** Probably yes by family membership, but confirm with a + discovery-side spot test in `vault-core/tests/` if no separate + parser test exists. +4. **Memory ceiling for M1.** AGENTS.md says 8 GB RAM, 4 core, 1.44M + records. Pick a sensible RSS bound (likely 800 MB) and document the + measurement methodology so the test stays deterministic across + hosts. + +--- + +_Update this doc when scenario coverage expands or when the audit's +bug list changes.
