You are the closer — verify the assembled work actually delivers the slice goal, then compress everything into a slice summary. After you finish, a **reassess-roadmap agent** reads your slice summary to decide if the remaining roadmap still makes sense. The slice summary is also the primary record of what this slice achieved — future slice researchers and planners read it as a dependency summary when their work builds on yours.\n\nWrite the summary for those downstream readers. What did this slice actually deliver? What patterns did it establish? What should the next slice know?\n\nAll relevant context has been preloaded below — the slice plan, all task summaries, and the milestone roadmap are inlined. Start working immediately without re-reading these files.\n\n## Inlined Context (preloaded — do not re-read these files)\n\n### Milestone Roadmap\nSource: `.gsd/milestones/M013/M013-ROADMAP.md`\n\n# M013: \n\n## Vision\nA fully automated CLI tool that tests FYN-LLM fitness, scores pipeline output across structural, content, voice preservation, readability, and preference dimensions, generates prompt variants, and runs unattended A/B optimization loops — producing reports with winning prompts and score trajectories. Starting with stage 5 synthesis (highest user-visible impact), expanding to all pipeline stages.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | General FYN-LLM Fitness Suite | medium | — | ✅ | Run `python -m pipeline.quality fitness` — outputs pass/fail for Mandelbrot question, JSON compliance, instruction following, and diverse prompt battery against live FYN-LLM |\n| S02 | Stage 5 Quality Scorer & Voice Preservation Dial | high | S01 | ✅ | Run scorer on a reference article — outputs composite score across 5 dimensions. Run same article at voice_level 0.2 vs 0.8 — voice preservation score differs meaningfully |\n| S03 | Prompt Variant Generator & Automated A/B Loop | high | S02 | ⬜ | Run `python -m pipeline.quality optimize --stage 5 --iterations 10` — generates prompt variants, scores each against reference articles, outputs leaderboard and score trajectory chart |\n| S04 | Expand to Pipeline Stages 2-4 | medium | S03 | ⬜ | Run `python -m pipeline.quality optimize --stage 3 --iterations 5` — optimizes extraction prompts with stage-appropriate scoring |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M013/slices/S03/S03-PLAN.md`\n\n# S03: Prompt Variant Generator & Automated A/B Loop\n\n**Goal:** Automated prompt optimization loop that generates LLM-powered prompt variants for Stage 5 synthesis, scores each against reference articles, and outputs a ranked leaderboard with score trajectories.\n**Demo:** After this: Run `python -m pipeline.quality optimize --stage 5 --iterations 10` — generates prompt variants, scores each against reference articles, outputs leaderboard and score trajectory chart\n\n## Tasks\n- [x] **T01: Created PromptVariantGenerator (LLM-powered prompt mutation) and OptimizationLoop (iterative generate→score→select engine) with full error tolerance and progress reporting** — Create two new modules: `variant_generator.py` with an LLM-powered prompt mutation engine, and `optimizer.py` with an optimization loop that orchestrates generate→score→select cycles.\n\n## Context\n\nThe existing `ScoreRunner.synthesize_and_score()` already chains Stage 5 synthesis through a modified prompt and scores the result. The `VoiceDial` class demonstrates the pattern of appending modifier text to the base prompt. This task builds the higher-level automation: an LLM generates prompt variants targeting weak dimensions, and a loop selects winners across iterations.\n\n## Key Interfaces\n\n- `LLMClient.complete(system_prompt, user_prompt, response_model, modality)` — drives both variant generation and synthesis\n- `ScoreRunner.synthesize_and_score(moments, creator_name, voice_level)` — scores a variant (uses voice_level=0.5 for neutral baseline)\n- `_load_prompt('stage5_synthesis.txt')` — loads the base prompt to optimize\n- `_get_stage_config(5)` — returns (model_override, modality) for Stage 5\n\n## Steps\n\n1. Create `backend/pipeline/quality/variant_generator.py`:\n   - Define a meta-prompt constant (`VARIANT_META_PROMPT`) that instructs the LLM to act as a prompt engineer. Given the current best prompt, its per-dimension scores, and the scoring rubric summary, produce a single modified variant targeting the weakest dimension(s). The meta-prompt MUST instruct the LLM to preserve the JSON output format section of the synthesis prompt unchanged.\n   - `PromptVariantGenerator.__init__(self, client: LLMClient)` — stores the LLM client\n   - `generate(self, base_prompt: str, scores: ScoreResult, n: int = 2) -> list[str]` — calls the LLM `n` times with the meta-prompt, each time asking for a variant. Validates each variant: must differ from base by ≥50 chars, must still contain the JSON format instruction markers (e.g. `SynthesisResult` or `\"pages\"` key reference). Returns list of valid variant prompt strings. Logs and skips invalid variants.\n\n2. Create `backend/pipeline/quality/optimizer.py`:\n   - `@dataclass OptimizationResult`: best_prompt (str), best_score (ScoreResult), history (list of dicts with iteration, variant_index, prompt_text, score fields), elapsed_seconds (float)\n   - `OptimizationLoop.__init__(self, client: LLMClient, stage: int, fixture_path: str, iterations: int, variants_per_iter: int)` — stores config, creates ScoreRunner and PromptVariantGenerator internally\n   - `run(self) -> OptimizationResult` — loads base prompt via `_load_prompt(f'stage{stage}_synthesis.txt')`, loads fixture data from JSON file, runs baseline `synthesize_and_score()`, then iterates: generate N variants → score each → keep best → repeat. Prints progress per iteration. Stores full history. Returns OptimizationResult.\n   - Handle LLM errors gracefully: if a variant's synthesis/scoring returns a ScoreResult with `error`, log it and skip that variant (don't abort the loop).\n\n3. Verify both modules import cleanly from project root.\n\n## Must-Haves\n\n- Meta-prompt instructs LLM to preserve JSON output format section\n- Variant validation: minimum diff from base, format markers present\n- Invalid/errored variants are skipped, not fatal\n- Progress output per iteration\n- OptimizationResult contains full history for downstream reporting\n  - Estimate: 1.5h\n  - Files: backend/pipeline/quality/variant_generator.py, backend/pipeline/quality/optimizer.py\n  - Verify: python -c \"from pipeline.quality.variant_generator import PromptVariantGenerator; print('generator ok')\" && python -c \"from pipeline.quality.optimizer import OptimizationLoop, OptimizationResult; print('optimizer ok')\"\n- [x] **T02: Added optimize CLI subcommand with leaderboard table, ASCII trajectory chart, and timestamped results JSON output** — Add the `optimize` subcommand to `__main__.py` that connects PromptVariantGenerator + OptimizationLoop to the CLI, and add formatted reporting: a leaderboard table and an ASCII score trajectory chart. Write results to a JSON file.\n\n## Context\n\nT01 produced `PromptVariantGenerator` and `OptimizationLoop` with `OptimizationResult`. This task wires them into the existing CLI (which already has `fitness` and `score` subcommands) and adds human-readable output.\n\n## Steps\n\n1. Add `optimize` subparser to `__main__.py`:\n   - `--stage` (int, default 5) — pipeline stage to optimize\n   - `--iterations` (int, default 10) — number of optimization iterations\n   - `--variants-per-iter` (int, default 2) — variants generated per iteration\n   - `--file` (str, required) — path to moments JSON fixture\n   - `--output-dir` (str, default `backend/pipeline/quality/results/`) — where to write result JSON\n   - Validate --stage is 5 (others not yet supported, print message and exit 1 for other values)\n   - Create output dir if it doesn't exist\n   - Instantiate `OptimizationLoop` with parsed args, call `run()`, handle result\n\n2. Add reporting functions (can be in `__main__.py` or a small `reporting.py`):\n   - `print_leaderboard(result: OptimizationResult)` — formatted table showing top 5 variants by composite score, with per-dimension breakdown. Use the same visual style as `ScoreRunner.print_report()` (plain print with alignment, score bars).\n   - `print_trajectory(result: OptimizationResult)` — ASCII line chart of composite score across iterations. ~20 rows height, iteration index on x-axis. Simple text rendering (no external deps).\n   - Print both after the optimization loop completes.\n\n3. Write results JSON:\n   - Save `OptimizationResult` to `{output_dir}/optimize_stage{N}_{timestamp}.json` with: best_prompt, best_scores, full history, config (stage, iterations, variants_per_iter, fixture_path), elapsed_seconds.\n   - Create `backend/pipeline/quality/results/.gitkeep` so the directory is tracked.\n\n4. Verify the full CLI flow:\n   - `python -m pipeline.quality optimize --help` shows all args\n   - `python -m pipeline.quality optimize --stage 5 --iterations 1 --file backend/pipeline/quality/fixtures/sample_moments.json` runs and either produces output (if LLM reachable) or shows clean connectivity error\n   - `python -m pipeline.quality optimize --stage 3` prints 'only stage 5 supported' and exits 1\n\n## Must-Haves\n\n- --stage, --iterations, --variants-per-iter, --file, --output-dir CLI args\n- Stage validation (only 5 supported currently)\n- Leaderboard table printed after loop\n- ASCII trajectory chart printed after loop\n- Results JSON written to output directory\n- Clean error handling (no tracebacks on LLM connectivity failure)\n  - Estimate: 1h\n  - Files: backend/pipeline/quality/__main__.py, backend/pipeline/quality/results/.gitkeep\n  - Verify: python -m pipeline.quality optimize --help && python -m pipeline.quality optimize --stage 3 --iterations 1 --file backend/pipeline/quality/fixtures/sample_moments.json 2>&1 | grep -q 'stage 5'\n\n---\n\n### Requirements\nSource: `.gsd/REQUIREMENTS.md`\n\n# Requirements\n\n## R001 — Whisper Transcription Pipeline\n**Status:** validated\n**Description:** Desktop Python script that accepts video files (MP4/MKV), extracts audio via ffmpeg, runs Whisper large-v3 on RTX 4090, and outputs timestamped transcript JSON with segment-level timestamps and word-level timing.

A complex slice with 5 tasks across multiple subsystems needs thorough verification and a detailed summary. Scale the work below accordingly.\n\nThen:\n1. Use the **Slice Summary** and **UAT** output templates from the inlined context above\n2. If a `GSD Skill Preferences` block is present in system context, use it and the `<available_skills>` catalog in your system prompt to decide which skills to load and follow for this unit, without relaxing required verification or artifact rules.\n3. Run all slice-level verification checks defined in the slice plan. All must pass before marking the slice done. If any fail, fix them first.\n4. If the slice plan includes observability/diagnostic surfaces, confirm they work. Skip this for simple slices that don't have observability sections.\n5. If the slice involved runtime behavior, fill the **Operational Readiness** section (Q8) in the slice summary: health signal, failure signal, recovery procedure, and monitoring gaps. Omit entirely for simple slices with no runtime concerns.\n6. If this slice produced evidence that a requirement changed status (Active → Validated, Active → Deferred, etc.), call `gsd_save_decision` with scope=\"requirement\", decision=\"{requirement-id}\", choice=\"{new-status}\", rationale=\"{evidence}\". Do NOT write `.gsd/REQUIREMENTS.md` directly — the engine renders it from the database.\n7. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S03/S03-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S03/S03-UAT.md` — a concrete UAT script with real test cases derived from the slice plan and task summaries. Include preconditions, numbered steps with expected outcomes, and edge cases. This must NOT be a placeholder or generic template — tailor every test case to what this slice actually built.\n9. Review task summaries for `key_decisions`. Append any significant decisions to `.gsd/DECISIONS.md` if missing.\n10. Review task summaries for patterns, gotchas, or non-obvious lessons learned. If any would save future agents from repeating investigation or hitting the same issues, append them to `.gsd/KNOWLEDGE.md`. Only add entries that are genuinely useful — don't pad with obvious observations.\n11. Call `gsd_complete_slice` with milestone_id, slice_id, the slice summary, and the UAT result. Do NOT manually mark the roadmap checkbox — the tool writes to the DB and renders the ROADMAP.md projection automatically.\n12. Do not run git commands — the system commits your changes and handles any merge after this unit succeeds.\n13. Update `.gsd/PROJECT.md` if it exists — refresh current state if needed.\n\n**You MUST call `gsd_complete_slice` with the slice summary and UAT content before finishing. The tool persists to both DB and disk and renders `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S03/S03-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M013/slices/S03/S03-UAT.md` automatically.**\n\nWhen done, say: \"Slice S03 complete.\"","display":false,"id":"96bb3542","parentId":"2d21c5ef","timestamp":"2026-04-01T09:10:43.551Z"}

Using asyncio.run() inside tasks risks nested event loop errors with gevent/eventlet workers. Using sync clients throughout eliminates this class of bug entirely.

Processing_status is set by stages 2-5 only. Embeddings can be regenerated by manual re-trigger. | Qdrant is at 10.0.0.10 on the hypervisor network and may not be reachable during all pipeline runs. Making embedding a non-blocking side-effect ensures core pipeline output (KeyMoments, TechniquePages in PostgreSQL) is never lost due to vector store issues.

Templates use XML-style content fencing. Pipeline stages read templates from disk at runtime, enabling edits without code changes.

Fall back to `settings.review_mode` config default when key is absent. | The config.py `review_mode` setting is loaded via lru_cache from environment variables and cannot be mutated at runtime. Redis is already used by the project (Celery broker, stage 4 classification data) so it adds no new infrastructure. A system_settings DB table would work but Redis is simpler for a single boolean toggle on a single-admin tool. The pipeline's stages.py reads settings.review_mode from config — the admin toggle only affects new pipeline runs if stages.py is updated to check Redis too, but that's deferred since the toggle is primarily a UI-level concept for the review queue. | Yes | agent |\n| D008 | M001/S04 | requirement | R004 Review Queue UI status | validated | All R004 capabilities delivered and verified: 9 API endpoints (approve, reject, edit, split, merge, queue list, stats, mode get/set) with 24 passing integration tests covering happy paths and error boundaries. React+TypeScript frontend with queue page (filter tabs, stats, pagination), moment detail page (all review actions with modals), and review-vs-auto mode toggle.

Keep existing sync `EmbeddingClient` and `QdrantManager` for Celery pipeline. Search endpoint has 300ms timeout on embedding API and falls back to SQL ILIKE keyword search on Qdrant/embedding failure. | The existing EmbeddingClient and QdrantManager are sync (using `openai.OpenAI` and `QdrantClient`) because Celery tasks run synchronously. FastAPI request handlers are async — reusing sync clients would block the event loop. Creating a thin async wrapper avoids modifying the battle-tested pipeline code while providing non-blocking search. The 300ms timeout and keyword fallback ensure the search endpoint always returns results, even when Qdrant or the embedding service is degraded. | Yes | agent |\n| D010 | M001/S05 | requirement | R005 Search-First Web UI status | validated | Search endpoint (GET /api/v1/search) with async embedding + Qdrant + keyword fallback implemented and tested.

SearchResults.tsx displays grouped results. 5 integration tests verify search happy path, empty query, keyword fallback, scope filter, and no-results. Frontend production build succeeds with zero TypeScript errors. | Yes | agent |\n| D011 | M001/S05 | requirement | R006 Technique Page Display status | validated | TechniquePage.tsx renders all specified sections: header with topic_category badge and topic_tags pills, creator name linked to creator detail, source_quality indicator, amber banner for unstructured content, body_sections JSONB prose (handles both string and object values), key moments index ordered by start_time, signal chains, plugins pill list, and related techniques links. Backend GET /api/v1/techniques/{slug} returns full detail with eager-loaded key_moments and related links. 404 for unknown slug tested. | Yes | agent |\n| D012 | M001/S05 | requirement | R007 Creators Browse Page status | validated | CreatorsBrowse.tsx implements genre filter pills, type-to-narrow name filter, sort toggle (Random default/A-Z/Views). Each creator row shows name, genre tags, technique_count, video_count. Links to CreatorDetail page. Backend GET /api/v1/creators supports sort=random\\|alpha\\|views and genre filter. Integration tests verify random sort, alpha sort, genre filter, detail endpoint, 404, and counts. | Yes | agent |\n| D013 | M001/S05 | requirement | R008 Topics Browse Page status | validated | TopicsBrowse.tsx renders two-level topic hierarchy (6 categories from canonical_tags.yaml with expandable sub-topics showing technique_count and creator_count). Filter input narrows categories/sub-topics. Clicking sub-topic navigates to search with scope=topics. Backend GET /api/v1/topics aggregates counts from DB per sub-topic. Integration test verifies topic hierarchy response shape. | Yes | agent |\n| D014 | M001/S05 | requirement | R014 Creator Equity status | validated | CreatorsBrowse.tsx defaults to sort=random. Backend uses func.random() ORDER BY for randomized sort. Integration test verifies random sort returns all creators (order may vary). All creators get equal visual weight in the UI — no featured/highlighted treatment. Equal-weight row layout confirmed in CSS. | Yes | agent |\n| D015 | M002/S01 | architecture | Docker network subnet for Chrysopedia on ub01 | 172.32.0.0/24 — free on ub01, replaces 172.24.0.0/24 which is used by xpltd_docs_default | 172.24.0.0/24 was already allocated to xpltd_docs_default network on ub01. Scanned all existing subnets and 172.32.0.0/24 was the first unoccupied /24 in the 172.x range. | Yes | agent |\n| D016 | M002/S01 | architecture | Embedding service for the pipeline and search — OpenWebUI doesn't serve /v1/embeddings | Add Ollama container (ollama/ollama:latest) to the compose stack running nomic-embed-text on CPU | The FYN OpenWebUI instance at chat.forgetyour.name returns 404/500 on /v1/embeddings. No Ollama instance exists on the network. Ollama provides the standard OpenAI-compatible /v1/embeddings endpoint that both EmbeddingClient and SearchService expect. | Yes | agent |\n| D017 |  | frontend | CSS theming approach for dark mode | 77 semantic CSS custom properties in :root block, all hardcoded colors replaced with var(--*) references | A complete variable-based palette enables theme switching, ensures consistency, and makes future color changes single-point edits. 77 tokens (vs ~30 initially planned) were needed to cover all semantic contexts — badges, buttons, surfaces, text, accents, shadows, and status states. Cyan (#22d3ee) replaces indigo as the accent color throughout. | Yes | agent |\n| D018 | M004/S04 | architecture | Version snapshot failure handling strategy in stage 5 | Best-effort versioning — snapshot INSERT failure logs ERROR but does not block page update (existing content overwrites proceed regardless) | Versioning is a diagnostic/benchmarking feature. Losing a version snapshot is far less damaging than failing the entire page synthesis. Follows the same non-blocking side-effect pattern established in D005 for embedding/Qdrant failures. | Yes | agent |\n| D019 | M005/S02 | frontend-layout | Technique page layout structure | CSS grid 2-column layout: 1fr main + 22rem sticky sidebar, collapsing to single column at 768px. Page max-width widened from 48rem to 64rem. | 22rem sidebar provides enough room for moment cards and plugin lists without cramming. 64rem total width accommodates both columns comfortably on standard desktop displays. Sticky sidebar keeps navigation aids visible while scrolling prose. 768px breakpoint aligns with existing mobile styles in the codebase. | Yes | agent |\n| D020 | M006/S05 | frontend | Topics page card layout visual differentiation approach | 3px colored left border + small colored dot next to category name, using existing badge CSS custom properties per category | Subtler than a full colored header — maintains dark theme cohesion while providing clear visual differentiation between 7 category cards. Reuses existing --color-badge-cat-*-bg/text custom properties, avoiding new color definitions. | Yes | agent |\n| D021 | M011 | scope | Which UI/UX assessment findings to implement in M011 | 12 of 16 findings approved; F01 (beginner paths), F02 (YouTube links), F03 (hide admin), F15 (CTA label) denied | User triaged each finding individually. Denied F01 because audience knows what they want. Denied F02 because no video URLs / don't want to link out. Denied F03 because admin dropdown is fine as-is. Denied F15 as low-value. | Yes | human |\n| D022 |  | requirement | R025 | validated | useDocumentTitle hook called in all 10 pages. Static pages set fixed titles, dynamic pages (SubTopicPage, CreatorDetail, TechniquePage, SearchResults) update title when async data loads. | Yes | agent |\n| D023 | M012/S01 | architecture | Qdrant embedding text enrichment strategy | Prepend creator_name and join topic_tags into embedding text for technique pages and key moments. Batch-resolve creator names at stage 6 start. | Semantic search now surfaces results for creator-name queries and tag-specific queries. Batch resolution avoids N+1 lookups during embedding. Reindex-all endpoint enables one-shot re-embedding after text composition changes. | Yes | agent |\n"}],"isError":false,"timestamp":1775034672144}}

This is by design; S04 will extend to stages 2-4.","milestoneId":"M013","narrative":"Built two core modules and wired them into the existing quality CLI. `variant_generator.py` provides `PromptVariantGenerator` — given a base prompt and its per-dimension scores, it calls the LLM with a meta-prompt to generate N variants targeting the weakest scoring dimensions. Each variant is validated: must differ from the base by ≥50 chars (via line-level symmetric difference), must preserve JSON format markers (`SynthesisResult`, `\"pages\"`). Invalid variants are logged and skipped.\n\n`optimizer.py` provides `OptimizationLoop` — loads the base stage 5 prompt and fixture data, runs a baseline score, then iterates: generate variants → score each via synthesis + the existing 5-dimension scorer → keep the best → repeat. The loop handles LLM errors gracefully (errored variants are skipped, not fatal). `OptimizationResult` captures the full history (iteration, variant index, prompt text, all scores) for downstream reporting.\n\nThe `optimize` CLI subcommand accepts `--stage`, `--iterations`, `--variants-per-iter`, `--file`, and `--output-dir`. Stage validation restricts to stage 5 (others print a clear message and exit 1). After the loop completes, three reporting functions fire: `print_leaderboard()` shows top 5 variants ranked by composite score with per-dimension breakdown; `print_trajectory()` renders a 15-row ASCII chart of best composite per iteration; `write_results_json()` persists the full result with config metadata to a timestamped JSON file.\n\nOne deviation from the plan: `OptimizationLoop._score_variant()` does its own synthesis call rather than delegating to `ScoreRunner.synthesize_and_score()`, because the loop owns the full prompt text directly and bypassing VoiceDial avoids double-application of voice modifiers.","observabilitySurfaces":[],"oneLiner":"Automated prompt optimization loop: LLM-powered variant generation, iterative scoring, CLI with leaderboard/trajectory output, and JSON result persistence.","patternsEstablished":["Meta-prompt pattern: LLM acts as prompt engineer, receives current prompt + per-dimension scores + rubric summary, outputs a modified variant targeting weakest dimensions","Variant validation gate: min-diff threshold + format marker check before scoring, invalid variants logged and skipped","Optimization history capture: full iteration×variant matrix stored in OptimizationResult for downstream leaderboard/charting/JSON export"],"provides":["optimize CLI subcommand for automated prompt A/B testing","PromptVariantGenerator for LLM-powered prompt mutation","OptimizationLoop + OptimizationResult for iterative optimization with full history","Leaderboard table, ASCII trajectory chart, and timestamped JSON result output"],"requirementsAdvanced":[{"how":"Prompt optimization loop provides automated mechanism to improve prompt templates — generates variants, scores them, and identifies winners","id":"R013"}],"requirementsInvalidated":[],"requirementsSurfaced":[],"requirementsValidated":[],"requires":[{"provides":"ScoreRunner, ScoreResult, LLMClient, 5-dimension scoring rubric, VoiceDial pattern","slice":"S02"}],"sliceId":"S03","sliceTitle":"Prompt Variant Generator & Automated A/B Loop","uatContent":"## UAT: S03 — Prompt Variant Generator & Automated A/B Loop\n\n### Preconditions\n- Working directory: project root (content-to-kb-automator)\n- Python environment with backend dependencies installed\n- `backend/pipeline/quality/fixtures/sample_moments.json` exists (created in S02)\n\n### Test 1: Module Imports\n**Steps:**\n1.
