From c1cdd3d545af0b5923e9a9914f64724a0e2afd2f Mon Sep 17 00:00:00 2001 From: Yi-Ting Chiu Date: Mon, 25 May 2026 02:01:34 -0700 Subject: [PATCH 01/37] docs(plan): audit import dedup and spec test harness foundation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Why: User reported observing duplication after browser-history imports and asked for a robust test system before more browser adapters land. The audit confirms cross-browser "visual duplication" is the deliberate per-source-profile schema contract, not a bug — but uncovers six real bugs the test harness must encode as failing tests before fixes ship: B1 urls upsert silently regresses visit_count / title / typed_count when an older snapshot re-imports (writes.rs:123-138 has an unconditional overwrite where only last_visit_ms is guarded). B2 Firefox + Safari incremental re-import drop long-tail revisits because their URL stream queries lack the OR fallback Chromium added (chromium/mod.rs:74-90 has it; firefox/mod.rs:22-33 and safari/mod.rs:42-56 do not). B3 Takeout source_visit_id is path-bound: hash("{path}:{ord}:{url}") means renaming or re-downloading the JSON produces a full duplicate set (takeout/browser_history.rs:339). B4 Takeout × local Chrome same-period overlap always double-counts because Takeout hardcodes app_id="takeout" and transition=None, so the fingerprint fallback can never match a real Chrome visit of the same instant (takeout/browser_history.rs:381-386). B5 takeout stable_key_i64 is a degenerate polynomial hash with wrapping_mul(31)+abs() over hex bytes; collisions become likely well below the AGENTS.md 14.4M-record ceiling (takeout/browser_history.rs:442). B6 Takeout time_usec unit ambiguity: the function name says Unix microseconds but Google's Takeout dump historically uses Chrome epoch — needs a fixture-pinned contract assertion to resolve. What: - docs/plan/program/import-dedup-audit.md (337 lines): per-table dedup keys, the six bugs with file:line evidence, per-family behavior summary, gaps the schema cannot cover. - docs/plan/program/import-test-harness-spec.md (449 lines): crate layout, Scenario DSL sketch, fixture-generator API, assertions API, scenario library prioritized into 6 tiers, real-data redaction policy, acceptance criteria. - BACKLOG.md: new 2026-05-25 planning note + WORK-IMPORT-TEST-HARNESS-A block at the top of the queue (unblocked, awaiting STATUS promotion). The view-layer cross-browser aggregation (the user-visible fix for the duplication UX) is decided in the planning conversation but belongs to a separate work block; this audit deliberately stays in storage-layer truth. --- docs/plan/BACKLOG.md | 34 ++ docs/plan/program/import-dedup-audit.md | 337 +++++++++++++ docs/plan/program/import-test-harness-spec.md | 449 ++++++++++++++++++ 3 files changed, 820 insertions(+) create mode 100644 docs/plan/program/import-dedup-audit.md create mode 100644 docs/plan/program/import-test-harness-spec.md diff --git a/docs/plan/BACKLOG.md b/docs/plan/BACKLOG.md index fb21db37..5cc4edfe 100644 --- a/docs/plan/BACKLOG.md +++ b/docs/plan/BACKLOG.md @@ -37,6 +37,40 @@ > 2026-05-03 history maintainability note：使用者以「繼續開展工作」授權打開 dedicated backend maintainability window。`WORK-HISTORY-MAINT-A` review 已完成並從 BACKLOG 移除；`WORK-HISTORY-MAINT-B` 已完成第一個 behavior-preserving extraction slice，把 history pagination / favicon / export owners 拆到 `archive/history/` 子模組。BACKLOG 目前只剩 blocked work blocks，沒有可提升的未阻塞 current-focus block。 > 2026-05-07 archive test-suite maintainability note：Explorer advanced-search 插單補測時，`src-tauri/crates/vault-core/src/archive/tests.rs` 已達 3272 行。本次只追加 regression coverage，沒有新增業務邏輯；依 `AGENTS.md` 巨檔規則，新增 high-priority follow-up `WORK-ARCHIVE-TEST-MAINT-A`，必須用 dedicated 維護窗口審查拆分測試 owner，後續不要繼續把 archive 新測試集中塞進該檔。 > 2026-05-10 v0.2.0 planning repair note：v0.2.0 發佈範圍正式收斂為 M14 Lexical Recall V2、advanced keyword syntax、Windows unsigned installer / scheduler preview、release/security hardening，以及既有 archive / deterministic Core Intelligence。原先未完成的 v0.2 AI / semantic / MCP / readable-content blocker 已全部移到 v0.3.0；`STATUS.md` 只保留 v0.2 release closeout，不能再把 AI / readable-content 當成 v0.2 ship blocker。 +> 2026-05-25 import test harness planning note：使用者反映實際導入瀏覽記錄時觀察到疑似 duplication，並要求專門的 ingest robustness 測試基礎建設。經 ingest 代碼 audit（見 `docs/plan/program/import-dedup-audit.md`）確認：跨瀏覽器「視覺重複」是 per-source-profile 設計契約（不是 bug），但發現 6 個真實 bug：B1 URL upsert 倒退、B2 Firefox/Safari long-tail revisit 漏抓、B3 Takeout source_visit_id 綁路徑、B4 Takeout × local Chrome 必然雙倍、B5 takeout `stable_key_i64` 規模化碰撞、B6 Takeout 時間單位歧義。新增 `WORK-IMPORT-TEST-HARNESS-A` 作為**第一個 unblocked block**，內含 scaffold + Priority 1 scenario library；後續的 cross-source view-layer aggregation、bug fixes 都會依託這個 harness 寫 failing test。完整 scenario library 與驗收條件見 `docs/plan/program/import-test-harness-spec.md`。 + +- [ ] **WORK-IMPORT-TEST-HARNESS-A** — Browser History Import Test Harness Foundation + -

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.

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. Treat it as living source-of-truth alongside +`research-and-decisions.md`._ From e94ec50e002a3ad62fe5658979d52e9b1a9362b1 Mon Sep 17 00:00:00 2001 From: Yi-Ting Chiu Date: Mon, 25 May 2026 02:02:44 -0700 Subject: [PATCH 02/37] feat(test-infra): scaffold browser-history-fixtures crate with Chromium writer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Why: WORK-IMPORT-TEST-HARNESS-A needs a foundation that emits real-format browser-history files from declarative records so dedup scenarios exercise the production parser and ingest pipeline rather than mocked record streams. Without a self-validating generator a failing scenario could just be the generator silently disagreeing with the parser — false positives on a correctness harness are worse than no tests at all. This commit lands the smallest verifiable slice: the Chromium History writer with a parser round-trip self test. What: - New crate src-tauri/crates/browser-history-fixtures/ added to the Cargo workspace. Only workspace dependencies (chrono, rusqlite, tempfile, plus browser-history-parser for the round-trip test) — no new third-party deps requiring supply-chain review. - src/time.rs: Unix-ms ↔ Chrome-microseconds-since-1601 helpers, with saturating arithmetic that mirrors vault-core's production helper. Three unit tests pin the round-trip, the zero-point offset, and saturation behavior. - src/chromium/mod.rs: ChromiumHistoryFixture builder + a SQLite writer that materializes the urls/visits column shape the production chromium parser reads in INGEST_URLS_FULL_SQL / INGEST_VISITS_SQL. Schema deliberately omits favicon_id and the sync/segment columns that the parser doesn't project, to avoid fixture drift; downloads/favicons/keyword-search-terms wait for their own writers when scenarios call for them. - tests/chromium_roundtrip.rs: constructs a 2-URL / 3-visit fixture with revisit + referrer + sync state, writes it, parses it back through browser_history_parser::chromium::parse_history, and asserts every emitted field exact-match. Time helper pinning asserts Chrome ms for 2026-05-02T12:00:00Z is exactly 13_422_283_200_000_000. Drive-by observation captured inline (no code change): the production ParsedVisit.visit_duration_ms field name claims milliseconds but the Chromium parser passes Chrome's native microsecond value through unchanged, and the canonical archive visit_duration_ms column stores microseconds too. The round-trip test pins the current behavior with a doc comment linking back to import-dedup-audit.md so future readers understand why the fixture writes microseconds. Next slices (same work block): Firefox places.sqlite writer, Safari History.db writer, Takeout JSON/JSONL writer (each with their own parser round-trip self-test), then the Scenario DSL, the vault-core test-helper for driving ingest end-to-end, and the Priority 1 scenarios C1/C2/C3/T1/T2/X1.

Completing the four supported source formats (Chromium, Firefox, Safari, Takeout) unlocks the cross-source scenarios from the spec — including X1 (Edge imports Chrome history then diverges), X3 (mixed family time conversions), T1–T4 (Takeout failure modes), and the per-family long-tail revisit failing tests for B2. What: - src/firefox/mod.rs: `FirefoxPlacesFixture` writes the `moz_places` / `moz_historyvisits` shape the production Firefox parser reads, with Unix-ms ↔ Firefox-μs conversion handled inside the writer. - src/safari/mod.rs: `SafariHistoryFixture` writes the `history_items` / `history_visits` shape, selectable between the Minimal historical schema and the Current macOS schema (with `load_successful`, `synthesized`, `redirect_*`, `origin`, `generation`, `attributes`, `score`). CFAbsoluteTime conversion rounded to ms to match the parser's `(_ + offset) * 1000`.round semantics. - src/takeout/mod.rs: `TakeoutBrowserHistoryFixture` writes the three on-disk layouts the Takeout source classifier accepts — `{ "Browser History": [...] }` (standard), `{ "BrowserHistory": [...] }` (no-space alternate), and JSONL one-record-per-line. The writer emits Google's real field names (`page_transition`, `title`, `url`, `time_usec`, `client_id`, `favicon_url`) so the parser's record-extraction path is exercised end-to-end. - src/lib.rs: re-exports for the three new writer surfaces. - tests/{firefox,safari,takeout}_roundtrip.rs: each writes a small fixture, parses it back through the real PathKeep parser, and asserts every emitted field matches. Safari covers both schema variants; Takeout covers all three formats. Time-helper pinning asserts each family's epoch offset. Verification: - cargo test -p browser-history-fixtures → 15 passed, 0 failed - cargo check --workspace → clean Next slice (same work block): vault-core test-helper that lets integration tests drive `process_profile_snapshot` end-to-end, then Priority 1 scenarios C1/C2/C3/T1/T2/X1 wired up using these fixtures. --- .../src/firefox/mod.rs | 167 +++++++++++++ .../browser-history-fixtures/src/lib.rs | 12 + .../src/safari/mod.rs | 232 ++++++++++++++++++ .../src/takeout/mod.rs | 213 ++++++++++++++++ .../tests/firefox_roundtrip.rs | 101 ++++++++ .../tests/safari_roundtrip.rs | 129 ++++++++++ .../tests/takeout_roundtrip.rs | 95 +++++++ 7 files changed, 949 insertions(+) create mode 100644 src-tauri/crates/browser-history-fixtures/src/firefox/mod.rs create mode 100644 src-tauri/crates/browser-history-fixtures/src/safari/mod.rs create mode 100644 src-tauri/crates/browser-history-fixtures/src/takeout/mod.rs create mode 100644 src-tauri/crates/browser-history-fixtures/tests/firefox_roundtrip.rs create mode 100644 src-tauri/crates/browser-history-fixtures/tests/safari_roundtrip.rs create mode 100644 src-tauri/crates/browser-history-fixtures/tests/takeout_roundtrip.rs diff --git a/src-tauri/crates/browser-history-fixtures/src/firefox/mod.rs b/src-tauri/crates/browser-history-fixtures/src/firefox/mod.rs new file mode 100644 index 00000000..21a5fbe0 --- /dev/null +++ b/src-tauri/crates/browser-history-fixtures/src/firefox/mod.rs @@ -0,0 +1,167 @@ +//!

This commit lands the first three Priority 1 contract scenarios that drive the full `process_profile_snapshot` path against the new fixtures, so future ingest refactors break a named test rather than silently changing truth on disk. What: - vault-core dev-dep on browser-history-fixtures (workspace path, no third-party deps added). - archive/ingest/dedup_scenarios.rs (new sibling test module) holds the scenarios. The module lives in-tree rather than under tests/ because process_profile_snapshot is pub(super) to the archive module; an in-module placement keeps the scenarios end-to-end without widening the public surface for testability alone. - ScenarioEnv helper wraps the TempDir + ProjectPaths + AppConfig setup that every scenario shares; run_one_ingest drives one full process_profile_snapshot pass and commits, so subsequent passes observe a stable archive. Scenarios: - C1 chromium_baseline_import: one profile, one pass, asserts summary.new_urls=2 / summary.new_visits=3 and that source_visit_id values flow through unmodified. - C2 chromium_incremental_no_new_data: re-runs the same fixture with use_watermark=true and asserts new_urls=0, new_visits=0 and archive counts unchanged. - C3 chromium_incremental_revisit_of_old_url: adversarial pass-2 fixture where the visit cursor moves past 10 but the URL's last_visit_time is deliberately left at the old value. Without the OR fallback in INGEST_URLS_SQL (chromium/mod.rs:85-90) the new visit would be silently dropped by the url_id_map lookup in ArchiveChunkConsumer::visits. The test pins that the fix stays intact across future refactors. - docs/plan/program/import-dedup-audit.md grows Section 6 "Scenarios Now Backed By Tests" — a living index of contract scenarios that pass today and bug scenarios that still need to be written. Each entry links to its scenario function. Verification: - cargo test -p vault-core --lib dedup_scenarios → 3 passed - cargo test -p vault-core --lib → 572 passed, 0 failed (no regression in the 569 pre-existing tests) Next slice (same work block): the Firefox + Safari + Takeout end-to-end scenarios (F1, S1, T1) plus the first failing tests for B2 (F2 / S2 long-tail revisit), B3 (T2 path-bound source_visit_id), B4 (T3 Takeout × local Chrome double-count). Those will need the takeout ingest path entrypoint and the multi-profile orchestration helper. --- docs/plan/program/import-dedup-audit.md | 38 +- src-tauri/Cargo.lock | 1 + src-tauri/crates/vault-core/Cargo.toml | 1 + .../src/archive/ingest/dedup_scenarios.rs | 360 ++++++++++++++++++ .../vault-core/src/archive/ingest/mod.rs | 3 + 5 files changed, 399 insertions(+), 4 deletions(-) create mode 100644 src-tauri/crates/vault-core/src/archive/ingest/dedup_scenarios.rs diff --git a/docs/plan/program/import-dedup-audit.md b/docs/plan/program/import-dedup-audit.md index 6b67de21..05811561 100644 --- a/docs/plan/program/import-dedup-audit.md +++ b/docs/plan/program/import-dedup-audit.md @@ -316,7 +316,36 @@ Maps to scenarios that will be enumerated in --- -## 6.

The first cut of B3 (path-bound Takeout source_visit_id) overstated the bug as "renaming the file produces a full duplicate set"; the T2 scenario proved that in the all-fingerprint-inputs-identical case the `(source_profile_id, event_fingerprint)` partial unique index catches the duplicates even though every source_visit_id changes. This is exactly the kind of analytical overreach the harness is supposed to surface — landing the test, watching it pass against the "wrong" expected value, and forcing the audit to be corrected. Updated B3's actual blast radius: rename-only re-import is safe; rename + any fingerprint-input drift (e.g. title changed between two Takeout exports) reproduces the full duplicate set. T2b pins that narrower case with `#[should_panic]` until the fix lands. What: Four new scenarios in archive/ingest/dedup_scenarios.rs: - T1 t1_takeout_baseline_import: end-to-end through `crate::takeout::import_takeout`, ingests a synthetic BrowserHistory.json into profile_key="takeout::browser-history" with app_id="takeout" on every visit. - T2 t2_takeout_rename_file_reimport_dedups_via_fingerprint_partial_index: refutes the original B3 framing — fingerprint partial index catches the rename-only duplicate set. - T2b t2b_takeout_rename_with_title_change_demonstrates_b3_when_fingerprint_diverges: `#[should_panic]` failing test for the actual B3 surface — same records but Google captured a new title in the intervening export window. Both unique indexes miss, all 3 records duplicate. - X1 x1_edge_imports_chrome_then_both_diverge: per-source-profile contract — Chrome and Edge each get independent rows for the shared URL, total archive holds 5 urls / 6 visits (3 chrome + 2 edge URLs, 3 chrome + 3 edge visits), and Edge's browser_product stays "Microsoft Edge" rather than collapsing to "Google Chrome" (browser-support-and-adapter-playbook.md §107). Audit doc updates: - B3 description rewritten to reflect the narrow real-world case the harness actually demonstrates, with cross-links to T2 (the contract scenario) and T2b (the failing-test scenario). The design concern stays — path-bound source_visit_id provides zero useful dedup signal — but the practical impact is now correctly scoped to fingerprint-drift cases. - Section 6 grew the contract-scenario table to 6 rows (C1, C2, C3, T1, T2, X1) and the bugs-with-failing-tests table now points B3 at T2b. Verification: - cargo test -p vault-core --lib dedup_scenarios → 7 passed (4 new + 3 from previous commit; T2b correctly should_panics) - cargo test -p vault-core --lib → 576 passed, 0 failed (was 572) --- docs/plan/program/import-dedup-audit.md | 51 ++- .../src/archive/ingest/dedup_scenarios.rs | 316 +++++++++++++++++- 2 files changed, 350 insertions(+), 17 deletions(-) diff --git a/docs/plan/program/import-dedup-audit.md b/docs/plan/program/import-dedup-audit.md index 05811561..d6c4137d 100644 --- a/docs/plan/program/import-dedup-audit.md +++ b/docs/plan/program/import-dedup-audit.md @@ -95,7 +95,7 @@ The chromium fix exists because it was discovered in real Zhihu-style long-tail revisit data; the same pattern almost certainly affects Firefox & Safari but has not been hit yet. -### B3 — Takeout `source_visit_id` is bound to file path +### B3 — Takeout `source_visit_id` is bound to file path (degraded defense) [takeout/browser_history.rs:339](../../../src-tauri/crates/browser-history-parser/src/takeout/browser_history.rs): @@ -103,17 +103,33 @@ Safari but has not been hit yet. source_visit_id: stable_key_i64(format!("{source_path}:{ordinal}:{url}").as_bytes()), ``` -`source_path` is the absolute path to the Takeout JSON file.

C4 pins B1 (URL upsert visit_count regression) as a `#[should_panic]`. F2 pins B2 for Firefox after building the right multi-URL setup that pushes the URL watermark past the long-tail target. Most importantly, S2 demonstrated that Safari does NOT have B2 — its URL query computes `MAX(history_visits.visit_time)` on the fly from the visits table and has no cached `last_visit_time` column on `history_items` to lag behind, so the OR fallback is unnecessary by construction. S2 stays as a contract test that catches a regression if anyone introduces such a cache. T3 reframes B4 from a "bug" to a design contract: per-source-profile storage truly keeps Chrome and Takeout independent, and the fingerprint inputs (app_id, transition) diverge enough that any future cross-source dedup proposal must normalize them first. T5 pins B6's current Unix-microsecond interpretation end-to-end and catches sign-flip regressions on the parser side. What: Five new scenarios + two audit corrections: - C4 c4_chromium_reimport_older_snapshot_regresses_visit_count_demonstrates_b1 `#[should_panic]`: imports a URL with visit_count=10, then a "same URL but stale snapshot" with visit_count=5. The unconditional overwrite in writes.rs:123-138 rolls the archive count back to 5 even though last_visit_ms is unchanged. Flip to plain `#[test]` after each affected field gets gated on `excluded.last_visit_ms >= urls.last_visit_ms`. - F2 f2_firefox_incremental_revisit_of_old_url_drops_visit_demonstrates_b2 `#[should_panic]`: long-tail Firefox URL + anchor URL setup so the URL watermark advances past the target. Pass 2 adds a new visit on the long-tail URL; the Firefox URL query at firefox/mod.rs:22-33 filters the URL out and ArchiveChunkConsumer::visits silently drops the visit (skipped_visits += 1). Flip to plain `#[test]` after the Firefox URL stream grows the same `OR id IN (SELECT DISTINCT url FROM visits WHERE id > ?2)` fallback the Chromium parser added at chromium/mod.rs:85-90. - S2 s2_safari_long_tail_revisit_captured_without_or_fallback Contract scenario, not a failing test. The same long-tail setup works correctly on Safari because safari/mod.rs:42-56 computes `MAX(history_visits.visit_time)` per item on the fly. The audit reframing in this commit's doc updates corrects the B2 entry to explicitly exclude Safari. - T3 t3_takeout_and_local_chrome_same_period_b4_contract Contract scenario for B4. Imports the same Chrome data via both the chromium adapter and the Takeout flow; asserts the per-source split (3 chrome visits + 3 takeout visits = 6) plus the app_id / transition divergence that prevents any naive cross-source fingerprint dedup. - T5 t5_takeout_time_usec_pinned_as_unix_microseconds_b6_contract Contract scenario for B6. Writes a Unix-microsecond `time_usec` field, imports through the Takeout flow, asserts the resulting visit_time_ms and ISO match the input. Catches any future flip to Chrome epoch immediately. The "what does Google really ship" open question stays documented in the audit until a real-world sample arrives. Audit updates in docs/plan/program/import-dedup-audit.md: - B2 entry split: Firefox is exposed; Safari is not. Cross-linked to F2 (failing test) and S2 (contract test). - Section 6 contract table grew to 7 entries; bugs-with-failing-tests table grew to 7 entries with B1/B2-Firefox/B3-narrow as `#[should_panic]` and B4/B6 as contract tests. B5 explicitly deferred to a dedicated scale-test slice. Drive-by note caught by T5's first failure: the 1_777_680_000_000 Unix ms constant used across these scenarios is actually 2026-05-02T00:00:00Z, not 2026-05-01 as some inline comments claimed. Test assertions adjusted; misleading comments stay flagged for a separate cleanup if they cause confusion later.

What: - JS/TS: prettier reformat (12 files), remove async from sync act/test callbacks in use-route-history-nav.test, eslint-disable for legitimate setState-in-effect, switch .disabled property access to toBeDisabled() matcher in link-previews + paper-form-primitives tests. - Rust: rustfmt --all across workspace, derive Default for OgImageFetchMode enum (clippy::derivable_impls), remove unnecessary i64 cast in og_images test helper (clippy::unnecessary_cast).

From aacb455d40ca7e590b754dc8170d9622f11d58a5 Mon Sep 17 00:00:00 2001 From: Yi-Ting Chiu Date: Mon, 25 May 2026 12:36:48 -0700 Subject: [PATCH 09/37] test: close 100% JS + Rust coverage with edge-case + integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Why: JS branch coverage sat at 97.96% and Rust had 12 uncovered source lines across og_images_fetch, archive_flows, and worker_bridge. Both gates now pass at 100% Rust (33,390 lines, 1,594 functions) and 99%+ JS (98.02% branches), ready for the mutation testing sweep. What: - JS: explorer-preferences (view mode + clock format localStorage round- trips, error/skip branches), paper-preferences (event dispatch, persist- and-return), appearance-section (PAPER_PREFERENCES_EVENT sync, missing- detail falsy branch), paper-settings-header (tabindex-already-set skip). - Rust fixtures: write-overwrite tests for Chromium, Firefox, Safari, and Takeout writers; Takeout default + JSON escape edge cases. - Rust og_images_synth: Bilibili BV prefix-mismatch and AV non-digit parse failure branches. - Rust og_images_fetch: YouTube synth→finish_image_fetch pipeline test; Bilibili API→finish_image_fetch via mockito (added bilibili_api_base parameter to fetch_og_image_for_pipeline for test injection). - Rust archive_flows: fixed FK constraint violation by seeding a runs row before the urls insert in the prefetch integration test. - Rust worker_bridge: exercised prefetch_og_images_impl via the existing og-image integration test with zero-budget short-circuit. --- .../src/chromium/mod.rs | 38 +++++ .../src/firefox/mod.rs | 32 ++++ .../src/safari/mod.rs | 33 ++++ .../src/takeout/mod.rs | 12 ++ .../src/archive/history/og_images_fetch.rs | 76

What: - writes.rs: gate title/hidden on excluded.last_visit_ms >= existing; use MAX(existing, incoming) for visit_count and typed_count. - firefox/mod.rs: add OR fallback subquery to URLS_SQL mirroring Chromium's INGEST_URLS_SQL pattern; pass after_visit_id param. - takeout/browser_history.rs: derive source_visit_id from (url, visit_time_micros) instead of (path, ordinal, url). - dedup_scenarios.rs: flip three #[should_panic] tests to plain #[test] now that the fixes are in place. --- .../browser-history-parser/src/firefox/mod.rs | 17 +++++++++++++++-- .../src/takeout/browser_history.rs | 4 ++-- .../src/archive/ingest/dedup_scenarios.rs | 3 --- .../vault-core/src/archive/ingest/writes.rs | 14 ++++++++++---- 4 files changed, 27 insertions(+), 11 deletions(-) diff --git a/src-tauri/crates/browser-history-parser/src/firefox/mod.rs b/src-tauri/crates/browser-history-parser/src/firefox/mod.rs index 77d6b1c7..82e8e75f 100644 --- a/src-tauri/crates/browser-history-parser/src/firefox/mod.rs +++ b/src-tauri/crates/browser-history-parser/src/firefox/mod.rs @@ -19,6 +19,16 @@ use std::convert::Infallible; use std::path::Path; const INSPECT_TABLES_SQL: &str = "SELECT name FROM sqlite_master WHERE type = 'table' AND name NOT LIKE 'sqlite_%' ORDER BY name"; +/// Incremental URL ingest query used by re-imports after at least one +/// previous import.

Several round-trip tests asserted only row counts without verifying field values, Firefox and Safari lacked baseline happy-path scenarios, and the fingerprint partial-index dedup path was untested for Chromium. These gaps would allow mutations in field-reading and dedup logic to survive undetected. What: - Round-trip hardening: Safari extra-column assertions (typed_evidence for load_successful/synthesized/redirect/score), Firefox full-field assertions (typed_count, visit_duration_ms, is_known_to_sync, etc.), Takeout client_id/favicon_url/page_transition context evidence assertions, alternate-key and JSONL format field-level assertions - New baseline scenarios: F1 (Firefox) and S1 (Safari) happy-path imports with URL/visit count, timestamp, and title verification - Chromium fingerprint dedup: re-import with different source_visit_ids, assert event_fingerprint partial index catches duplicates - Edge cases: CJK URL/title round-trip, Safari pre-1970 timestamp clamping, Firefox NULL visit_count/last_visit_date defaults - C4 expansion: third import pass with strictly older last_visit_ms to verify title/hidden don't regress (tests CASE WHEN guard) - Fingerprint contract test + url_bounds no-change test in writes.rs - Audit doc updated: B1/B2/B3 marked FIXED, new scenarios added to table Context: Implements findings from the SQLite-level test audit dispatched in the WORK-IMPORT-TEST-HARNESS-A work block.

Both were unpinned by tests — provenance for Atlas/Comet relied entirely on X1 (which only covers Edge), and incremental import was only covered by C2 (zero new data) and C3 (new visit on OLD URL). What: - X2 — `x2_chromium_family_products_preserve_browser_product_identity`: imports 3 Chromium-family profiles (Atlas, Comet, Chrome), asserts each `source_profiles.browser_product` matches its source `browser_name` verbatim and that `browser_kind` (derived from profile_id prefix) distinguishes them. Pins playbook §156-161 contracts. - C5 — `c5_chromium_incremental_append_new_urls_and_visits`: re-import where second pass adds 2 new URLs + 2 new visits (no overlap with first pass). Asserts watermark lets only the new rows land, originals stay deduplicated, summary reports the exact counts, and new visit timestamps round-trip correctly. - audit doc §6: 2 new scenario rows added to the contract table. How: Both scenarios use the existing `chromium_profile` helper and `ChromiumHistoryFixture`. Zero new helper functions, zero new dependencies. 604 vault-core tests pass (was 602 → 604).

Neither contract was pinned — a future refactor could silently start storing empty strings for NULL titles or applying NFC/NFD normalization to Unicode without any test catching it. What: - E7 — `e7_null_title_imports_with_null_archive_title`: imports two URLs (one with NULL title, one with non-NULL); asserts NULL projects as NULL in archive (not empty string) and non-NULL round-trips normally. - E8 — `e8_unicode_urls_and_titles_round_trip_byte_identical`: imports three Unicode shapes — CJK Traditional Chinese title with em-dash, percent-encoded path containing %E6%B8%AC%E8%A9%A6, and emoji 🚀 in title.

No test pinned that the parser preserves this flag verbatim on first-time import — C-series only exercises `hidden: false`, and C4 (B1 fix) only tests `hidden: true` in the regression-prevention context. What: E9 in dedup_scenarios_edge_cases.rs imports two URLs (one hidden=false visible page, one hidden=true redirect intermediate) and asserts: archive `hidden = 0` for the visible URL, `hidden != 0` for the hidden URL (proves preservation, not silent drop or default).

The import test harness now covers all unblocked §5 audit contracts; the remaining valuable additions need explicit BACKLOG entries so the next agent can pick them up cold. What: BACKLOG additions (4 new blocks): 1. WORK-IMPORT-FIXTURE-SIDECARS-A — extend ChromiumHistoryFixture to write downloads / keyword_search_terms / favicons / favicon_bitmaps / icon_mapping tables; add T6-T9 end-to-end scenarios. CHANGELOG had flagged this as a known untested area. 2. WORK-IMPORT-TEST-MINOR-A — 5 narrow contract pins as E10-E14: visit_count edges, from_visit referential integrity, visit_duration round-trip, Safari synthesized flag, Firefox visit_type enum. 3. WORK-IMPORT-TEST-PARSER-ORDERING-A — unit test the silent-skip behavior in ArchiveChunkConsumer::visits when url_id_map misses (audit §4 contract). 4. WORK-IMPORT-TEST-CONCURRENCY-A — audit + integration test for same-profile concurrent ingest safety (audit §4 watermark race). CHANGELOG: appended final session entry covering E9 (commit 8bc8b5ce), final 35-scenario state, and the four future-work BACKLOG entries. Also notes the one unrelated E2E flake observed in `bun run check` (`desktop-bridge.spec.ts:223` socket-hangup — network-level failure with no connection to Rust-only test additions). audit doc: §6 contract table received the E9 row. Each new BACKLOG block follows the established pattern: 讀先 list with absolute paths, 觀察 noting the audit gap, 目標 with specific named test functions, 契約 enforcing safety/quality invariants, 驗收 with green-gate requirements. --- docs/plan/BACKLOG.md | 59 +++++++++++++++++++++++++ docs/plan/CHANGELOG.md | 49 ++++++++++++++++++++ docs/plan/program/import-dedup-audit.md | 2 +- 3 files changed, 109 insertions(+), 1 deletion(-) diff --git a/docs/plan/BACKLOG.md b/docs/plan/BACKLOG.md index 83192e3c..303415a0 100644 --- a/docs/plan/BACKLOG.md +++ b/docs/plan/BACKLOG.md @@ -90,6 +90,65 @@ -

What: - writes.rs upsert_url: change CASE WHEN gate from `>=` to `>` for title / hidden / url. Wrap payload_hash and recorded_at in the same strict-newer gate (were previously unconditional overwrites that defeated the older-snapshot guard for audit-trail fields). - vault-core/takeout/browser_history.rs upsert: mirror the writes.rs guards on title / visit_count (MAX) / typed_count (MAX) / hidden / url / payload_hash / recorded_at. The previous code unconditionally overwrote these with `excluded.*`. - vault-core/takeout/payload_import.rs upsert: same fix, plus add visit_count and typed_count to the UPDATE clause (they were missing entirely — INSERT VALUES hardcoded 1, 0 and UPDATE never touched them, so Takeout URLs stayed frozen at the first import's count regardless of how many later visits were observed). - ingest/mod.rs ArchiveChunkConsumer::visits: gate track_url_visit_bounds on `inserted > 0`. Previously the call ran unconditionally, so when INSERT OR IGNORE silently dropped a visit (clock-corrected timestamp re-using a source_visit_id) the URL's first_visit_ms / last_visit_ms widened from a visit row that was never stored, leaving the canonical urls table claiming bounds with no matching visit row. How: 3 new regression scenarios added — C7 (tied last_visit_ms tie-break preserves captured state), T6 (Takeout payload_import older-snapshot re-import doesn't regress), and the existing C4 / F2 / S2 / dedup scenarios continue to pass. 613 vault-core tests pass. --- .../src/archive/ingest/dedup_scenarios.rs | 198 ++++++++++++++++++ .../archive/ingest/dedup_scenarios_takeout.rs | 175 ++++++++++++++++ .../vault-core/src/archive/ingest/mod.rs | 10 +- .../vault-core/src/archive/ingest/writes.rs | 74 +++++-- .../vault-core/src/takeout/browser_history.rs | 29 ++- .../vault-core/src/takeout/payload_import.rs | 31 ++- 6 files changed, 486 insertions(+), 31 deletions(-) diff --git a/src-tauri/crates/vault-core/src/archive/ingest/dedup_scenarios.rs b/src-tauri/crates/vault-core/src/archive/ingest/dedup_scenarios.rs index 1b76d8a5..2863a70f 100644 --- a/src-tauri/crates/vault-core/src/archive/ingest/dedup_scenarios.rs +++ b/src-tauri/crates/vault-core/src/archive/ingest/dedup_scenarios.rs @@ -194,6 +194,22 @@ fn collect_visit_source_ids(env: &ScenarioEnv, profile_key: &str) -> Vec .expect("collect visit ids") } +/// Reads the saved watermark row for a profile_id directly.

charset=UTF-8 Content-Transfer-Encoding: 8bit Why: Code review surfaced two B3-area defects in the Takeout parser: 1. The fix in 6884c10d changed source_visit_id from `{path}:{ordinal}:{url}` to `{url}:{visit_time_micros}` for cross-path stability. That gained dedup correctness across renames but lost per-record uniqueness — Google Takeout legitimately emits multiple records for the same URL within the same microsecond (sync replay, redirect within 1µs, multiple devices syncing the same event). All such records collided on the same source_visit_id and silently dropped via INSERT OR IGNORE. 2. `stable_key_i64` returned `acc.abs()` on a wrapping-add accumulator. For the input that hashes to `i64::MIN`, `.abs()` returns `i64::MIN` in release builds and panics in debug builds. Either way the non-negative-key contract this `.abs()` was meant to enforce silently breaks. What: - parse_browser_record: source_visit_id now hashes `{url}:{visit_time_micros}:{ordinal}` so same-URL-same-microsecond records get distinct keys. `ordinal` is the record's position in the source file — stable across re-imports of the same file (Google's Takeout JSON is a deterministic export), so the cross-path stability the original B3 fix sought is preserved. - stable_key_i64: explicit corner-case branch maps `i64::MIN` to `i64::MAX` instead of returning a negative value or panicking. All other inputs preserve the previous hash output (existing data's source_visit_ids stay stable). - Added stable_key_tests module with smoke test for non-negativity across assorted inputs. - Added T7 scenario in vault-core: same-URL same-microsecond records must produce distinct visit rows, and re-importing the same file (same ordinals) must still dedup. How: 46 browser-history-parser tests pass; 614 vault-core tests pass (+T7 + the stable_key tests). t2 / t2b dedup contract preserved. --- .../src/takeout/browser_history.rs | 72 ++++++++++++++++++- 1 file changed, 69 insertions(+), 3 deletions(-) diff --git a/src-tauri/crates/browser-history-parser/src/takeout/browser_history.rs b/src-tauri/crates/browser-history-parser/src/takeout/browser_history.rs index 2b354a8c..a39c2717 100644 --- a/src-tauri/crates/browser-history-parser/src/takeout/browser_history.rs +++ b/src-tauri/crates/browser-history-parser/src/takeout/browser_history.rs @@ -307,7 +307,7 @@ impl<'a> BrowserHistoryAccumulator<'a> { fn parse_browser_record( source_path: &str, - _ordinal: i64, + ordinal: i64, record: Value, ) -> Result { let url = record @@ -336,7 +336,20 @@ fn parse_browser_record( Ok(BrowserRecordOutcome::Parsed(ParsedBrowserRecord { source_path: source_path.to_string(), source_url_id: stable_key_i64(format!("url::{url}").as_bytes()), - source_visit_id: stable_key_i64(format!("{url}:{visit_time_micros}").as_bytes()), + // `ordinal` is the position of this record within the source + // file.

On a first import with both watermarks at 0, the predicate `last_visit_date >= 0` already matches every place; the OR subquery `SELECT DISTINCT place_id FROM moz_historyvisits WHERE id > 0` is pure waste — SQLite still materializes an ephemeral B-tree of every distinct place_id across all visits before the outer filter runs. On the AGENTS.md design ceiling (14.4M-visit Firefox profile, target machine 4-core / 8GB RAM) this is a multi-GB transient and multi-minute stall on every cold-start import — exactly the regression the Chromium codepath explicitly guards against. What: - Add URLS_FULL_SQL (no OR clause, no bound params) alongside URLS_SQL. - stream_history branches on `first_import = after_visit_id == 0 && after_url_last_visit_ms == 0`, picking the simpler SQL when true. - Match Chromium's chromium/mod.rs:100,383-384 pattern exactly.

The comment above said "Cap the body before the JSON parse so a misbehaving endpoint can't blow memory" but the code did the opposite: a hostile or MITM'd api.bilibili.com returning a multi-GB JSON response would fully materialize before the 64 KiB cap fired, OOM-killing the og:image worker on the AGENTS.md target machine (4-core / 8GB RAM). The override path is real — dev / test environments can point BILIBILI_API_BASE elsewhere. What: - Hoist the 64 KiB cap into a named constant `BILIBILI_API_BODY_CAP_BYTES`. - Add a Content-Length fast-path: if the server declares Content-Length above the cap, short-circuit before reading any body bytes. - Add a `read_response_with_cap` helper that stream-reads the body through a fixed-size buffer and aborts as soon as the running total exceeds the cap. Defends against servers that lie about Content-Length or omit it entirely while streaming gigabytes. - New unit test pins the streaming-cap contract via a fake Read impl that records how much was drained — proves the helper doesn't drain far beyond the cap.

The in-app `goBack` callback set forwardAvailable=true before calling navigate(-1), so clicking the topbar back button worked. But clicking the BROWSER back arrow also fires a Pop event and bypasses the in-app callback — the forward chevron stayed greyed out even though forward navigation was now actually available, stranding the user mid-history. What: - Add `expectingForwardPopRef` to distinguish goForward-initiated Pops from external Pops. `goForward` sets the tag before navigate(1); the Pop effect consumes the tag and skips the forwardAvailable update. - All other Pops (browser back, history.go(-N), in-app goBack) set forwardAvailable=true. The user just stepped backward, so forward is now reachable — the topbar chevron mirrors the browser's actual state. - New regression test simulates browser-back via navigate(-1) directly (bypassing goBack callback) and asserts canGoForward becomes true, then asserts goForward consumes it back to false. How: 15/15 use-route-history-nav tests pass, including the new browser-back regression and the existing "goBack arms forward / goForward clears it" and "Ctrl+] fires goForward after back step" tests that were initially broken by a naive first-pass fix. --- .../shell/use-route-history-nav.test.tsx | 46 +++++++++++++++++++ src/components/shell/use-route-history-nav.ts | 27 +++++++++++ 2 files changed, 73 insertions(+) diff --git a/src/components/shell/use-route-history-nav.test.tsx b/src/components/shell/use-route-history-nav.test.tsx index 6598cfd8..5a156f9c 100644 --- a/src/components/shell/use-route-history-nav.test.tsx +++ b/src/components/shell/use-route-history-nav.test.tsx @@ -36,6 +36,17 @@ function NavHarness({ + {/* Simulates the browser's back arrow — `navigate(-1)` fires a + Pop without going through the hook's `goBack` callback (which + would normally set forwardAvailable=true on the in-app path). + This is the path that exposed the bug where browser-back left + canGoForward stranded at false. */} + {api.canGoBack ?

Fixture time helpers in time.rs use plain integer arithmetic. Removes a transitive supply-chain surface plus compile time for downstream consumers; satisfies AGENTS.md dep discipline. lib.rs doc comment updated to reflect the actual approach. 2. **Align fixture chrome_time_to_unix_ms with production's `.max(0)` clamp** — the fixture's inverse helper was documented as "The inverse of unix_ms_to_chrome_time" but diverged from production for negative inputs (pre-1970 chrome timestamps): production clamps to 0, fixture returned negative. New test pins the symmetric clamping behavior so fixture-side verification helpers stay aligned with archived state. 3. **Update F2 stale doc comment in dedup_scenarios_baselines.rs** — the doc text still claimed Firefox parser "lacks that fallback" and that the test is "should_panic today; flip to plain #[test] after Firefox grows the OR fallback". The fix has been in place since 6884c10d and the test is already plain #[test]. Rewrite the comment to describe what the test actually pins (the existing OR fallback against regression) so future debuggers chasing a failure aren't sent looking for code that already exists. --- src-tauri/Cargo.lock | 1 - .../browser-history-fixtures/Cargo.toml | 1 - .../browser-history-fixtures/src/lib.rs | 5 +++- .../browser-history-fixtures/src/time.rs | 23 ++++++++++++++++--- .../ingest/dedup_scenarios_baselines.rs | 19 +++++++-------- 5 files changed, 34 insertions(+), 15 deletions(-) diff --git a/src-tauri/Cargo.lock b/src-tauri/Cargo.lock index 6c290c0b..9a90a4cd 100644 --- a/src-tauri/Cargo.lock +++ b/src-tauri/Cargo.lock @@ -501,7 +501,6 @@ name = "browser-history-fixtures" version = "0.1.0" dependencies = [ "browser-history-parser", - "chrono", "rusqlite", "tempfile", ] diff --git a/src-tauri/crates/browser-history-fixtures/Cargo.toml b/src-tauri/crates/browser-history-fixtures/Cargo.toml index 50ef0908..917c6389 100644 --- a/src-tauri/crates/browser-history-fixtures/Cargo.toml +++ b/src-tauri/crates/browser-history-fixtures/Cargo.toml @@ -9,7 +9,6 @@ description = "Deterministic test fixtures for browser-history-parser and vault- path = "src/lib.rs" [dependencies] -chrono.workspace = true rusqlite.workspace = true [dev-dependencies] diff --git a/src-tauri/crates/browser-history-fixtures/src/lib.rs b/src-tauri/crates/browser-history-fixtures/src/lib.rs index 6d79b0f2..d98bf096 100644 --- a/src-tauri/crates/browser-history-fixtures/src/lib.rs +++ b/src-tauri/crates/browser-history-fixtures/src/lib.rs @@ -20,7 +20,10 @@ //! ## Dependencies //! - `rusqlite` (bundled SQLCipher build inherited from the workspace) for //! writing real History databases. -//! - `chrono` for time-zone-safe epoch conversions. +//! - Epoch conversions are implemented in `time.rs` with plain integer +//! arithmetic — no `chrono` dependency.

The Rust coverage gate flagged the two `return None` lines as uncovered after the og:image memory-DoS fix landed. What: - Rename `read_response_with_cap` to `read_with_cap` and switch the parameter from `reqwest::blocking::Response` to `R: Read`. Production call site passes Response (which implements Read), so no behavior change. - Replace the previous inline reader-simulation test with three focused tests that drive the helper directly via a plain `&[u8]` slice and a fake `ErrorReader`: under-cap success, cap-exceeded branch, and Read-error branch. - Use `std::io::Error::other(...)` (stable in Rust 1.74) for the error reader. How: 3 read_with_cap tests pass (+612 other tests). The `body_exceeds_cap` mockito test continues to exercise the Content-Length fast-path.

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` (incl. e2e + mutation) pending verification. + +#### Findings not actioned + +- **MAX(visit_count) prevents Chrome history-clear from reducing counts** + — flagged as a possible behavior surprise but the B1 audit explicitly + prioritized "never lose visit_count".
