All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\n## UNIT: Complete Slice S01 (\"Homepage Hero & Value Proposition\") — Milestone M009\n\n## Your Role in the Pipeline\n\nExecutor agents built each task and wrote task summaries. 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/M009/M009-ROADMAP.md`\n\n# M009: Homepage & First Impression\n\n## Vision\nThe homepage is Chrysopedia's front door. Right now it's a search box — functional but says nothing about why this exists. After this milestone, a music producer lands on the page and immediately understands: this is distilled production knowledge from real creators, organized so you don't have to watch 4-hour tutorials. That first impression converts browsers to users.\n\n## Slice Overview\n| ID | Slice | Risk | Depends | Done | After this |\n|----|-------|------|---------|------|------------|\n| S01 | Homepage Hero & Value Proposition | medium | — | ⬜ | Homepage shows tagline, value description, how-it-works steps, Start Exploring CTA, and popular topic quick-links above the fold |\n| S02 | About Page | low | — | ⬜ | About page at /about explains what Chrysopedia is, how content is extracted, and who maintains it. Link visible in footer. |\n| S03 | Featured Content & Content Teasers | low | S01 | ⬜ | Homepage shows a featured technique spotlight and Recently Added section with enriched cards |\n\n---\n\n### Slice Plan\nSource: `.gsd/milestones/M009/slices/S01/S01-PLAN.md`\n\n# S01: Homepage Hero & Value Proposition\n\n**Goal:** Homepage shows tagline, value description, how-it-works steps, Start Exploring CTA, and popular topic quick-links above the fold\n**Demo:** After this: Homepage shows tagline, value description, how-it-works steps, Start Exploring CTA, and popular topic quick-links above the fold\n\n## Tasks\n- [x] **T01: Added hero tagline \"Production Knowledge, Distilled\", value proposition, 3-step how-it-works grid, and \"Start Exploring\" CTA to homepage** — The Home.tsx hero section currently has an empty <h1> and a subtitle. This task adds the tagline text, a value proposition paragraph, a 3-step how-it-works visual, and a Start Exploring CTA button — all static content with CSS styling using existing design tokens.\n\nSteps:\n1. Read `frontend/src/pages/Home.tsx` and `frontend/src/App.css` (home-hero section starting ~line 866)\n2. In Home.tsx, add text content to the existing empty `<h1 className=\"home-hero__title\">` — set it to \"Production Knowledge, Distilled\" (or similar compelling tagline)\n3. Add a new `<p className=\"home-hero__value-prop\">` below the subtitle explaining what Chrysopedia does — e.g. \"Real music production techniques extracted from creator tutorials. Skip the 4-hour videos — find the insight you need in seconds.\"\n4. Add a `<div className=\"home-how-it-works\">` section with 3 steps: (1) Real creators share techniques (2) AI extracts key moments (3) You find answers fast. Each step gets an icon/number, title, and short description.\n5. Add a `<Link to=\"/topics\" className=\"btn home-cta\">Start Exploring</Link>` CTA button positioned prominently after the how-it-works section but before the search bar\n6. In App.css, add styles for `.home-hero__value-prop`, `.home-how-it-works`, `.home-how-it-works__step`, `.home-cta`. Use existing CSS custom properties (--color-text-secondary, --color-accent, --color-bg-surface, etc.)\n7. Increase `.home-hero` top padding to give breathing room for the new content\n8. Add mobile responsive rules at the existing breakpoint (~768px) — steps should stack vertically on mobile\n9. Run `cd frontend && npm run build` to verify zero errors\n\nConstraints:\n- Keep search bar prominent — new content supports but doesn't bury it\n- Use only existing CSS custom properties from :root, no new color definitions\n- The how-it-works section can be just below the fold on desktop; hero title + search should be visible without scrolling\n  - Estimate: 30m\n  - Files: frontend/src/pages/Home.tsx, frontend/src/App.css\n  - Verify: cd frontend && npm run build 2>&1 | tail -5\n- [x] **T02: Added popular topics pill-link section to homepage that fetches from topics API, sorts sub-topics by technique_count, and renders top 8 as clickable pills** — Add a popular topics section to the homepage that fetches topic data from the existing fetchTopics API, sorts sub-topics by technique_count, and renders the top 8-10 as clickable pill/chip links. Each pill navigates to the search page scoped to that topic.\n\nSteps:\n1. Read current `frontend/src/pages/Home.tsx` (will include T01 changes) and `frontend/src/api/public-client.ts` (for TopicCategory/TopicSubTopic interfaces and fetchTopics function)\n2. In Home.tsx, import `fetchTopics` and `TopicCategory` from public-client.ts\n3. Add state: `const [popularTopics, setPopularTopics] = useState<{name: string; count: number}[]>([])`\n4. Add useEffect that calls fetchTopics(), flattens all sub_topics across categories, sorts by technique_count descending, takes top 8, maps to {name, count}\n5. Render a `<section className=\"home-popular-topics\">` between the CTA and the search bar (or between search bar and nav-cards). Show heading \"Popular Topics\" and render each topic as `<Link to={`/search?q=${encodeURIComponent(topic.name)}&scope=topics`} className=\"pill pill--topic-quick\">{topic.name}</Link>`\n6. If popularTopics is empty (no data or API error), render nothing — no section, no error message\n7. In App.css, add styles for `.home-popular-topics` (centered, flex-wrap gap layout) and `.pill--topic-quick` (reuse existing pill styling with minor adjustments for interactive hover state using --color-accent)\n8. Add mobile responsive adjustments if needed\n9. Run `cd frontend && npm run build` to verify zero errors\n\nConstraints:\n- Catch fetchTopics errors silently — no user-facing error for this optional section\n- Reuse existing pill/badge CSS patterns (`.pill--tag` exists already)\n- Topic pills should visually complement but not compete with the search bar\n  - Estimate: 25m\n  - Files: frontend/src/pages/Home.tsx, frontend/src/App.css\n  - Verify: cd frontend && npm run build 2>&1 | tail -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/M009/slices/S01/S01-SUMMARY.md` (compress all task summaries).\n8. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M009/slices/S01/S01-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/M009/slices/S01/S01-SUMMARY.md` and `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M009/slices/S01/S01-UAT.md` automatically.**\n\nWhen done, say: \"Slice S01 complete.\"","display":false,"id":"a8fd2f8f","parentId":"bf7aa3f8","timestamp":"2026-03-31T05:37:10.473Z"}
