+```
+
+### Two-Tier Fixture Strategy
+
+**Tier-1: Tiny Synthetics** (in `formats/`, `edge/`, `hostile/`)
+Small, project-generated files for format-compatibility matrices and fast unit tests.
+These are always-regeneratable by the generator scripts and are used for breadth.
+
+**Tier-2: Real Heroes** (in `valid/`)
+Content-representative files for integration and fidelity tests. Includes:
+- Big Buck Bunny video clips (CC-BY, Blender Foundation)
+- macOS TTS speech in 6 audio formats (CC0)
+- Project-generated synthetics (QR codes, barcodes, OCR text images, PDFs)
+- Portrait/scene photos for AI tool tests (some UNVERIFIED-REVIEW, see manifest)
+
+Every `valid/` file is tracked in `manifest.json` with sha256 hash, byte count,
+source URL, and license. The manifest guard test (`fixture-manifest.test.ts`)
+verifies disk matches manifest on every run.
+
+### Typed Fixture Registry
+
+Always import fixture paths from `tests/fixtures/index.ts`:
+
+```ts
+import { fixtures, readFixture, fixtureDir } from "../../fixtures/index.js";
+
+// Named paths (type-checked, IDE autocomplete)
+const pngPath = fixtures.image.base.png200;
+const heroMp4 = fixtures.video.hero.mp4;
+
+// Read file bytes
+const buffer = readFixture(fixtures.image.base.png200);
+
+// Format accessor (for matrix iteration)
+const arwPath = fixtures.image.formats("arw");
+const mp4Path = fixtures.video.tiny("mp4");
+
+// Directory paths (for glob/scan patterns)
+const hostileDir = fixtureDir.image.hostile;
+```
+
+### Guard Tests
+
+Four guard tests protect fixture integrity:
+
+| Guard | Location | What it checks |
+|-------|----------|----------------|
+| fixture-resolve | `unit/fixtures/` | Every registry path exists and is non-empty |
+| fixture-budget | `unit/fixtures/` | Per-extension size caps prevent bloat |
+| fixture-manifest | `unit/fixtures/` | sha256/bytes in manifest.json match disk |
+| fixture-integrity | `integration/fixtures/` | Real heroes decode through Sharp/ffprobe/qpdf |
+
+Additional parity guards:
+
+| Guard | Location | What it checks |
+|-------|----------|----------------|
+| tool-registry-drift | `unit/shared/` | Frontend registry matches shared TOOLS catalog |
+| tool-route-drift | `integration/` | API routes match shared TOOLS catalog |
+| i18n-completeness | `unit/shared/` | All 21 locales have all required keys |
+
+### Adding a Fixture
+
+1. Add the file to the appropriate modality directory (`image/valid/`, `video/formats/`, etc.)
+2. Add a named key in `tests/fixtures/index.ts`
+3. Run `node tests/fixtures/gen-manifest.mjs` (for `valid/` files)
+4. Fill in `sourceUrl` and `license` in `manifest.json`
+5. Update `LICENSES.md` if the file has third-party origin
+6. Run guards: `pnpm vitest run tests/unit/fixtures/`
+
+## Generator Scripts
+
+Three generators produce deterministic synthetics. All are idempotent and skip
+files that already exist (to avoid breaking manifest hashes from encoder-version
+differences). Pass `--force` to `gen-synthetic-content.mjs` to overwrite.
+
+| Script | Scope | Outputs |
+|--------|-------|---------|
+| `scripts/generate-test-fixtures.mjs` | Tier-1 format samples | `video/formats/tiny.mp4`, `audio/formats/tiny.{mp3,wav}`, `document/formats/tiny.{docx,xlsx,epub,html,md}`, `document/valid/encrypted.pdf` |
+| `scripts/generate-hostile-fixtures.mjs` | Hostile inputs | `image/hostile/{truncated.jpg,zero-byte.png,garbage.jpg,png-bytes.jpg,bomb-50000x50000.png}` |
+| `tests/fixtures/gen-synthetic-content.mjs` | CC0 synthetics | QR codes, barcodes, OCR text images, PDFs, SVG logo, multi-face placeholder, animated GIF, tagged MP3, metadata MP4 |
+
+The generators do NOT touch committed real heroes (BBB videos, TTS speech, UNVERIFIED-REVIEW photos).
+
+## Running Tests
+
+```bash
+# Full suite
+pnpm test                    # All unit + integration tests
+pnpm test:unit               # Unit tests only
+pnpm test:integration        # Integration tests only
+
+# Single file
+pnpm vitest run tests/unit/my-test.test.ts
+pnpm vitest run tests/integration/my-test.test.ts
+
+# Fixture guards only
+pnpm vitest run tests/unit/fixtures
+
+# E2E (Playwright)
+pnpm test:e2e                # Main app (chromium + serial + visual projects)
+pnpm test:e2e:landing        # Landing site
+pnpm test:e2e:docs           # VitePress docs
+pnpm test:e2e:analytics      # Analytics flows
+pnpm test:docker             # Full Docker container test
+
+# Editor e2e (no root alias)
+pnpm playwright test --config playwright.editor.config.ts
+
+# Single e2e spec
+pnpm playwright test tests/e2e/my-test.spec.ts
+```
+
+### Environment Requirements
+
+Unit and integration tests need Postgres + Redis:
+
+```bash
+docker compose -f docker-compose.dev.yml up -d
+export DATA_DIR=/tmp/so-test-data && mkdir -p "$DATA_DIR"
+```
+
+Each Vitest fork gets its own Postgres DB clone + workspace + isolated `BULLMQ_PREFIX`
+via `tests/setup/per-fork-env.ts` (testcontainers for Postgres). 30s test timeouts.
+
+### E2E Projects
+
+The main Playwright config defines three projects:
+
+- **chromium**: Parallel-safe specs, 2 workers (override via `PW_WORKERS`)
+- **chromium-serial**: Global-state specs, 1 worker
+- **chromium-visual**: Screenshot comparison specs (platform-suffixed baselines)
+
+Auth setup project logs in and saves storage state. The `webServer` block spins up
+both dev servers with a fresh test DB.
+
+### Environment Switches
+
+| Variable | Effect |
+|----------|--------|
+| `FULL_MATRIX=1` | Run all format x tool combinations (nightly) |
+| `FUZZ=1` + `FUZZ_RUNS=N` | Property-based fuzz testing (nightly) |
+| `PW_WORKERS=N` | Override Playwright worker count |
+
+### CI Pipeline
+
+PRs run: lint, typecheck, unit, integration (4 shards), e2e smoke.
+Nightly: full e2e, cross-browser, docker suite, full matrix + fuzz, coverage.

+| `gui-responsive.spec.ts` | 82 | Superseded by `device-mobile.spec.ts` + `device-tablet.spec.ts`. All responsive chrome, overflow, layout tests covered by device specs with real touch/DPR. |
+
+## Repaired
+
+| Spec | Tests | Fix |
+|------|-------|-----|
+| `rbac.spec.ts` | 5 | Fixed `storageState: "test-results/.auth/user.json"` to `authFile` import from `playwright.config.ts` (path is `.playwright/.auth/user.json`). |
+| `settings.spec.ts` | 8 | Same auth-path fix in the skipped `API Keys section has generate button` test. |
+| `state-bleed-audit.spec.ts` | 8 | Updated all bare tool routes (`/resize` -> `/image/resize`, `/rotate` -> `/image/rotate`, etc.) to match 2.0 `/:modality/:toolId` routing. |
+| `gui-file-carry.spec.ts` | 6 | Same bare-route fix + URL assertions (`toHaveURL("/resize")` -> `toHaveURL("/image/resize")`). |
+| `full-session.spec.ts` | 8 | Same bare-route fix for resize, rotate, convert, crop, compress, strip-metadata. |
+| `gui-settings-rbac.spec.ts` | 39 (2 with bare routes) | Fixed 2 tests that navigated to `/resize` instead of `/image/resize`. |
+
+## Quarantined (skipped via `test.skip()`)
+
+| Spec | Tests | Reason | Tractability | Follow-up |
+|------|-------|--------|--------------|-----------|
+| `gui-performance.spec.ts` | 62 | 62 tests use bare tool routes (`/resize`, `/compress`, `/rotate`, etc.) that 404 on the 2.0 prod preview. Mechanical route fix is needed, but the file also references selectors (fullscreen grid search, tool-list layout, sidebar tool entries) that need 2.0 UI verification after route fix. | Medium -- route fix is mechanical, selector verification needs UI run | Phase 4 tail |
+| `theme.spec.ts` | 3 | Asserts `button[title='Toggle Theme']` in footer and `Privacy Policy` link visibility. The 2.0 UI hides the footer on mobile viewports and may have changed the theme toggle mechanism. | Low -- 3 tests, needs UI verification | Phase 4 tail |
+
+## Still-running serial specs (not quarantined, expected to pass)
+
+These specs use proper role-based/text-based selectors and the `openSettings()` helper.
+They were validated by code review and partial test run:
+
+- `gui-settings-general.spec.ts` (56 tests) -- settings dialog navigation, general tab, system settings, about, AI features, tools deep, analytics, audit log
+- `gui-settings-expanded.spec.ts` (77 tests) -- dialog state management, extended settings persistence
+- `gui-settings-rbac.spec.ts` (39 tests) -- admin/editor/user role visibility, endpoint verification
+- `gui-settings-people.spec.ts` (35 tests) -- people tab CRUD, teams tab, roles tab
+- `gui-settings-security.spec.ts` (15 tests) -- change password form, API keys tab
+- `gui-settings-apikeys.spec.ts` (15 tests) -- API key generation, scoping, deletion
+- `gui-settings-tools.spec.ts` (12 tests) -- tool enable/disable, analytics consent
+- `settings.spec.ts` (8 tests) -- basic settings dialog open/close
+- `rbac.spec.ts` (5 tests) -- admin/user/editor role tab visibility
+- `rbac-full.spec.ts` (8 tests) -- people management, roles, audit log, API key scoping, custom roles
+- `people.spec.ts` (15 tests) -- people API CRUD + UI table/search/actions
+- `security.spec.ts` (21 tests) -- authentication, session, CSRF, API security
+- `api.spec.ts` (20 tests) -- API endpoint tests
+- `i18n.spec.ts` (15 tests) -- locale detection, switching, persistence, RTL
+- `state-bleed-audit.spec.ts` (8 tests) -- cross-tool state isolation (repaired)
+- `full-session.spec.ts` (8 tests) -- end-to-end tool workflows (repaired)
+- `gui-file-carry.spec.ts` (6 tests) -- file carry between tools (repaired)
+
+## Local doc-binary skips (not quarantine, informational)
+
+The following integration test files skip cleanly via `describe.skipIf`
+because `pandoc`, `libreoffice`/`soffice`, `pdfcpu`, and `pdf2docx` are not
+installed on this development machine. These pass in CI where the Docker image
+provides all binaries:
+
+- `convert-document.test.ts`
+- `epub-convert.test.ts`
+- `html-to-pdf.test.ts`
+- `doc-to-pdf.test.ts`
+- `pdf-to-docx.test.ts`
+- `compress-pdf.test.ts`
+- `pdf-to-image.test.ts`
+
+Total local integration skips: 217 tests across 7 files.
+
+## Summary
+
+| Category | Files | Tests |
+|----------|-------|-------|
+| Removed (superseded) | 3 | 136 |
+| Repaired (route + auth fixes) | 6 | 74 |
+| Quarantined (`test.skip`) | 2 | 65 |
+| Running (not quarantined) | 17 | 389 |
+
+65 tests remain quarantined for Phase 4 tail follow-up (mostly the
+`gui-performance.spec.ts` bare-route bulk fix + UI verification).

+- `security/*` (SVG XXE test vectors)
+- `formats/sample.*` (format samples, 35 files)
+
+## NEEDS HUMAN LICENSE SIGN-OFF (Category C: UNVERIFIED-REVIEW)
+
+The following `content/` assets have unverifiable provenance. They were added
+during the test coverage expansion (commit `babca4cf`) without recorded source
+URLs. They are real-world photos containing faces or identifiable people that
+require human review to either:
+
+1. Verify they are CC0/CC-BY and record the source, OR
+2. Replace them with properly-licensed alternatives.
+
+**Do NOT delete these.** Depth tests (face detection, colorization, red-eye
+removal, stress testing) depend on real-world content.
+
+| Path | Size | Content Description | Why Review Is Needed |
+|------|------|---------------------|---------------------|
+| `content/portrait-bw.jpeg` | 2.7 MB | B&W portrait of a woman (3775x5662) | Real photo, no EXIF source. Used for colorization tests. |
+| `content/portrait-color.jpg` | 89 KB | Business portrait, man in suit (572x1024) | Likely AI-generated but unconfirmed. Used for face/portrait tests. |
+| `content/portrait-color-dup.jpg` | 89 KB | Identical to portrait-color.jpg | Deliberate duplicate for dedup testing. Same license concern. |
+| `content/portrait-headshot.heic` | 1.5 MB | HEIC portrait headshot | No EXIF source. Used for HEIC format tests with face content. |
+| `content/portrait-isolated.png` | 81 KB | Same subject as portrait-color, background removed | Derived from portrait-color.jpg. Same license concern. |
+| `content/red-eye.jpg` | 369 KB | Woman with red-eye effect (800x460) | Canon EOS 400D DIGITAL, 2007. Real photo, no source URL. |
+| `content/ocr-scanned.pdf` | 1.0 MB | Scanned document PDF | Unknown scanned content. Used for OCR-on-PDF tests. |
+| `content/stress-large.jpg` | 6.7 MB | Muay Thai boxing match (4000x3000) | Samsung Galaxy S24 Ultra photo. Contains identifiable people. |
+| `content/watermark.jpg` | 87 KB | Mountain lake landscape with text watermark (720x480) | Real landscape photo. Unknown source. |
+| `content/motorcycle.heif` | 224 KB | HEIF image | Content not inspectable without HEIF decoder. |
+
+### Resolved in This Phase
+
+The following were previously in this section and have been resolved:
+
+- **`content/cross-format-chat.webp`** and **`content/ocr-chat.jpeg`**: Replaced with CC0 mock chat-bubble images (Sharp SVG render). No third-party UI content.
+- **`content/speech-10s.wav`** and **`content/speech-10s.mp4`**: Replaced with macOS TTS-generated speech (CC0). Transcribable text for Whisper tests.
+- **`content/media-30s.mp4`**: Replaced with Big Buck Bunny (CC-BY 3.0, Blender Foundation). Real video with motion + audio.
+
+### Recommended Actions for Remaining Sign-Off
+
+- **Portraits** (5 files): If AI-generated, confirm the generator and its license terms. If stock photos, identify the source. Consider replacing with CC0 portraits from a known source.
+- **Red-eye photo**: Source the original from the photographer or replace with a CC0 red-eye portrait.
+- **Stress-large photo**: If this is a project contributor's personal photo, have them release it under CC0. Otherwise replace.
+- **Watermark landscape**: Source the underlying landscape photo. The watermark overlay was likely added by the project.
+- **Motorcycle HEIF**: Inspect via HEIF viewer and determine source.
+- **OCR-scanned PDF**: Inspect document content and determine source.

+# Test Fixtures
+
+Shared test fixtures for the SnapOtter test suite. Organized by modality in two tiers.
+
+## Two-Tier Structure
+
+**Tier 1: Tiny Synthetics (matrices/format coverage)**
+Small, project-generated files for format-compatibility matrices and fast unit tests.
+Located in `*/formats/`, `*/edge/`, `*/hostile/`, and `security/`.
+
+**Tier 2: Real Heroes (depth/fidelity testing)**
+Larger, content-representative files for integration and fidelity tests.
+Located in `*/valid/`. Each must be tracked in `manifest.json` with sha256 + provenance.
+
+## Modality-First Layout
+
+```
+tests/fixtures/
+  index.ts            # Typed registry (import paths from here, not raw strings)
+  manifest.json       # sha256 + bytes + provenance for all valid/ assets
+  gen-manifest.mjs    # Script to re-stamp manifest hashes
+  gen-synthetic-content.mjs  # Regenerate CC0 synthetics (QR, barcode, OCR, etc.)
+  LICENSES.md         # Provenance audit trail

+    edge/             # Edge cases (1x1, blank, extreme aspect, fake transparency)
+    hostile/          # Truncated, zero-byte, garbage, bomb, extension-mismatch

+    edge/             # remote-img.html (SSRF test vector)
+    hostile/          # Truncated DOCX, garbage PDF
+  data/
+    valid/            # tiny.{csv,json,xml,yaml,tsv,zip}
+  security/           # SVG XXE test vectors (file-read, SSRF)
+```
+
+## Using the Registry
+
+Always import paths from `tests/fixtures/index.ts` rather than hard-coding paths:
+
+```ts
+import { fixtures, readFixture } from "../../fixtures/index.js";
+
+// Direct path access
+const pngPath = fixtures.image.base.png200;
+
+// Read bytes
+const buffer = readFixture(fixtures.image.base.png200);
+
+// Format accessor (for matrix iteration)
+const arwPath = fixtures.image.formats("arw");
+const mp4Path = fixtures.video.tiny("mp4");
+```
+
+## Adding a Fixture
+
+1. Add the file to the appropriate modality directory
+2. Add a key in `tests/fixtures/index.ts` pointing to it
+3. Run `node tests/fixtures/gen-manifest.mjs` (for `valid/` files)
+4. Fill in `sourceUrl` and `license` in `manifest.json` (required)
+5. Update `LICENSES.md` with the provenance record
+6. Run the guards: `pnpm vitest run tests/unit/fixtures/`
+
+## Licensing Gate
+
+Every `valid/` hero must have a verified license (CC0, CC-BY, CC-BY-SA, or
+public-domain). Assets with `UNVERIFIED-REVIEW` need license review before
+release. The manifest guard test reports the current count.
+
+## Guard Tests
+
+Four guard tests protect fixture integrity:
+
+- **fixture-resolve** (unit): every registry path exists and is non-empty
+- **fixture-budget** (unit): per-extension size caps prevent bloat
+- **fixture-manifest** (unit): sha256/bytes in manifest.json match disk
+- **fixture-integrity** (integration): real heroes decode through Sharp/ffprobe/qpdf
+
+## Generator Scripts
+
+Three generators produce deterministic synthetics. All are idempotent and skip
+existing files to avoid breaking manifest hashes. See `tests/README.md` for details.
