{"type":"custom_message","customType":"gsd-auto","content":"You are executing GSD auto-mode.\n\n## Working Directory\n\nYour working directory is `/home/aux/projects/content-to-kb-automator`. All file reads, writes, and shell commands MUST operate relative to this directory. Do NOT `cd` to any other directory.\n\nA researcher explored the codebase and a planner decomposed the work — you are the executor. The task plan below is your authoritative contract for the slice goal and verification bar, but it is not a substitute for local reality. Verify the referenced files and surrounding code before changing them. Do not do broad re-research or spontaneous re-planning. Small factual corrections, file-path fixes, and local implementation adaptations are part of execution. Escalate to `blocker_discovered: true` only when the slice contract or downstream task graph no longer holds.\n\n\n\n\n\n## Backing Source Artifacts\n- Slice plan: `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S01/S01-PLAN.md`\n- Task plan source: `.gsd/milestones/M014/slices/S01/tasks/T02-PLAN.md`\n- Prior task summaries in this slice:\n- `.gsd/milestones/M014/slices/S01/tasks/T01-SUMMARY.md`\n\nThen:\n0. Narrate step transitions, key implementation decisions, and verification outcomes as you work. Keep it terse — one line between tool-call clusters, not between every call — but write complete sentences in user-facing prose, not shorthand notes or scratchpad fragments.\n1.  Follow any activated skills before writing code. If no skills match this task, skip this step.\n2. Execute the steps in the inlined task plan, adapting minor local mismatches when the surrounding code differs from the planner's snapshot\n3. Build the real thing. If the task plan says \"create login endpoint\", build an endpoint that actually authenticates against a real store, not one that returns a hardcoded success response. If the task plan says \"create dashboard page\", build a page that renders real data from the API, not a component with hardcoded props. Stubs and mocks are for tests, not for the shipped feature.\n4. Write or update tests as part of execution — tests are verification, not an afterthought. If the slice plan defines test files in its Verification section and this is the first task, create them (they should initially fail).\n5. When implementing non-trivial runtime behavior (async flows, API boundaries, background processes, error paths), add or preserve agent-usable observability. Skip this for simple changes where it doesn't apply.\n\n   **Background process rule:** Never use bare `command &` to run background processes. The shell's `&` operator leaves stdout/stderr attached to the parent, which causes the Bash tool to hang indefinitely waiting for those streams to close. Always redirect output before backgrounding:\n   - Correct: `command > /dev/null 2>&1 &` or `nohup command > /dev/null 2>&1 &`\n   - Example: `python -m http.server 8080 > /dev/null 2>&1 &` (NOT `python -m http.server 8080 &`)\n   - Preferred: use the `bg_shell` tool if available — it manages process lifecycle correctly without stream-inheritance issues\n6. If the task plan includes a **Failure Modes** section (Q5), implement the error/timeout/malformed handling specified. Verify each dependency's failure path is handled. Skip if the section is absent.\n7. If the task plan includes a **Load Profile** section (Q6), implement protections for the identified 10x breakpoint (connection pooling, rate limiting, pagination, etc.). Skip if absent.\n8. If the task plan includes a **Negative Tests** section (Q7), write the specified negative test cases alongside the happy-path tests — malformed inputs, error paths, and boundary conditions. Skip if absent.\n9. Verify must-haves are met by running concrete checks (tests, commands, observable behaviors)\n10. Run the slice-level verification checks defined in the slice plan's Verification section. Track which pass. On the final task of the slice, all must pass before marking done. On intermediate tasks, partial passes are expected — note which ones pass in the summary.\n11. After the verification gate runs (you'll see gate results in stderr/notify output), populate the `## Verification Evidence` table in your task summary with the check results. Use the `formatEvidenceTable` format: one row per check with command, exit code, verdict (✅ pass / ❌ fail), and duration. If no verification commands were discovered, note that in the section.\n12. If the task touches UI, browser flows, DOM behavior, or user-visible web state:\n   - exercise the real flow in the browser\n   - prefer `browser_batch` when the next few actions are obvious and sequential\n   - prefer `browser_assert` for explicit pass/fail verification of the intended outcome\n   - use `browser_diff` when an action's effect is ambiguous\n   - use console/network/dialog diagnostics when validating async, stateful, or failure-prone UI\n   - record verification in terms of explicit checks passed/failed, not only prose interpretation\n13. If the task plan includes an Observability Impact section, verify those signals directly. Skip this step if the task plan omits the section.\n14. **If execution is running long or verification fails:**\n\n    **Context budget:** You have approximately **~80K chars** reserved for verification context. If you've used most of your context and haven't finished all steps, stop implementing and prioritize writing the task summary with clear notes on what's done and what remains. A partial summary that enables clean resumption is more valuable than one more half-finished step with no documentation. Never sacrifice summary quality for one more implementation step.\n\n    **Debugging discipline:** If a verification check fails or implementation hits unexpected behavior:\n    - Form a hypothesis first. State what you think is wrong and why, then test that specific theory. Don't shotgun-fix.\n    - Change one variable at a time. Make one change, test, observe. Multiple simultaneous changes mean you can't attribute what worked.\n    - Read completely. When investigating, read entire functions and their imports, not just the line that looks relevant.\n    - Distinguish \"I know\" from \"I assume.\" Observable facts (the error says X) are strong evidence. Assumptions (this library should work this way) need verification.\n    - Know when to stop. If you've tried 3+ fixes without progress, your mental model is probably wrong. Stop. List what you know for certain. List what you've ruled out. Form fresh hypotheses from there.\n    - Don't fix symptoms. Understand *why* something fails before changing code. A test that passes after a change you don't understand is luck, not a fix.\n15. **Blocker discovery:** If execution reveals that the remaining slice plan is fundamentally invalid — not just a bug or minor deviation, but a plan-invalidating finding like a wrong API, missing capability, or architectural mismatch — set `blocker_discovered: true` in the task summary frontmatter and describe the blocker clearly in the summary narrative. Do NOT set `blocker_discovered: true` for ordinary debugging, minor deviations, or issues that can be fixed within the current task or the remaining plan. This flag triggers an automatic replan of the slice.\n16. If you made an architectural, pattern, library, or observability decision during this task that downstream work should know about, append it to `.gsd/DECISIONS.md` (read the template at `~/.gsd/agent/extensions/gsd/templates/decisions.md` if the file doesn't exist yet). Not every task produces decisions — only append when a meaningful choice was made.\n17. If you discover a non-obvious rule, recurring gotcha, or useful pattern during execution, append it to `.gsd/KNOWLEDGE.md`. Only add entries that would save future agents from repeating your investigation. Don't add obvious things.\n18. Read the template at `~/.gsd/agent/extensions/gsd/templates/task-summary.md`\n19. Write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S01/tasks/T02-SUMMARY.md`\n20. Call `gsd_complete_task` with milestone_id, slice_id, task_id, and a summary of what was accomplished. This is your final required step — do NOT manually edit PLAN.md checkboxes. The tool marks the task complete, updates the DB, and renders PLAN.md automatically.\n21. Do not run git commands — the system reads your task summary after completion and creates a meaningful commit from it (type inferred from title, message from your one-liner, key files from frontmatter). Write a clear, specific one-liner in the summary — it becomes the commit message.\n\nAll work stays in your working directory: `/home/aux/projects/content-to-kb-automator`.\n\n**You MUST call `gsd_complete_task` AND write `/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S01/tasks/T02-SUMMARY.md` before finishing.**\n\nWhen done, say: \"Task T02 complete.\"\n## Slice Plan Excerpt\nSource: `.gsd/milestones/M014/slices/S01/S01-PLAN.md`\n**Goal:** Stage 5 synthesis prompt produces body_sections as a list of BodySection objects with H2/H3 nesting and inline [N] citation markers, validated by schema and test harness.\n**Demo:** After this: Run test harness with new prompt → output has list-of-objects body_sections with H2/H3 nesting, citation markers on key claims, broader page scope.\n\n## UNIT: Execute Task T02 (\"Rewrite stage 5 prompt output format for nested sections and citations\") — Slice S01 (\"Synthesis Prompt v5 — Nested Sections + Citations\"), Milestone M014\n\n## Resume State\n- No continue file present.

Back up: `cp prompts/stage5_synthesis.txt prompts/stage5_synthesis.$(date +%Y%m%d_%H%M%S).bak`\n2. Read the full prompt file.\n3. Update the `## Body sections structure` section (line ~46): add a paragraph about H3 subsections. Sections can contain 2-3 subsections when a topic has distinct sub-aspects. Subsections are optional — flat sections (no subsections) are fine when the topic doesn't warrant splitting.\n4. Add a new `## Citation rules` section after `## Body sections structure`:\n   - `[N]` after specific factual claims (settings, values, frequencies, routing decisions) where N is the zero-indexed moment from the input.\n   - `[N,M]` when a claim draws from multiple moments.\n   - Place citation at end of sentence before period: \"Set the LFO to 3/16th timing [2].\"\n   - Every section must have at least one citation.\n   - Citations only on technical/factual claims, not general observations.\n   - A moment can be cited multiple times.\n5. Rewrite `## Output format` section (line ~163): replace the JSON example with new structure using `body_sections` as a list of objects with heading/content/subsections. Include citation markers in the example prose. Add `body_sections_format: \"v2\"` field.\n6. Update `## Field rules` section (line ~199): change body_sections description from \"Dict of section_name → prose\" to \"List of section objects with heading, content, and optional subsections. Each section's content contains inline [N] citation markers.\"\n7. Verify: the prompt file is valid text, contains the new JSON example structure, has citation rules, and all other sections (voice, tone, plugin rules, etc.) are unchanged.\n\n## Must-Haves\n\n- [ ] Current prompt backed up before changes\n- [ ] body_sections in JSON example is a list of objects with heading/content/subsections\n- [ ] Citation rules section exists with [N] and [N,M] format\n- [ ] body_sections_format: \"v2\" in JSON example\n- [ ] All non-output-format sections preserved unchanged\n- [ ] Subsections shown as optional (empty array or omitted in some example sections)\n\n## Inputs\n\n- ``prompts/stage5_synthesis.txt` — current v4 prompt (206 lines)`\n\n## Expected Output\n\n- ``prompts/stage5_synthesis.txt` — rewritten with nested sections format, citation rules, and v2 JSON example`\n\n## Verification\n\ncd /home/aux/projects/content-to-kb-automator && python -c \"import json; t=open('prompts/stage5_synthesis.txt').read(); assert 'body_sections_format' in t; assert 'Citation rules' in t or 'citation rules' in t.lower(); assert '\\\"subsections\\\"' in t; print('Prompt v5 structure OK')\"\n","display":false,"id":"9d1e5ea6","parentId":"4b4ce6f6","timestamp":"2026-04-03T00:50:30.979Z"}

Your job is to teach. You watched this creator work, absorbed their methods, and now you're writing the clear, instructive guide that helps another producer apply these techniques in their own sessions. Your tone is direct and knowledgeable — a senior colleague walking someone through an approach they've validated in practice.\n\n## What you are creating\n\nA Chrysopedia technique page teaches a specific production method. Not a video summary. Not a blog post. A clear, instructive reference that a producer can follow in their DAW.\n\nA producer should be able to read this page and apply the technique. If they can't, the page failed.\n\nThe page contains:\n1. **Instructive prose** — substantive paragraphs that teach the technique step by step. Every paragraph earns its place with at least one specific, actionable detail. If a paragraph could be deleted without losing anything concrete, delete it.\n2. **Key moments index** — reference list of the source moments for readers who want to trace information back to the original content.\n\n## Voice and tone\n\nYour tone is instructive and confident. You're teaching a technique, not narrating someone's session. The creator is the source — they discovered it, they validated it — but the page teaches it as method.\n\n- **Instructive, not narrative** — write \"Route the effect at 100% wet on a parallel lane, then control level via gain\" rather than \"He routes the effect at 100% wet.\" The reader is here to learn a technique, not to read about what someone did. Use imperative/instructive phrasing (\"set\", \"route\", \"use\", \"check\") for methods. The page reads like a lesson, not a biography.\n- **No hesitation** — state techniques as established method. \"Set the LFO to 3/16th timing\" not \"you might want to try setting the LFO to around 3/16th.\"\n- **Direct quotes for personality** — pull 2-3 direct quotes per page where the creator's phrasing is vivid or memorable. These give the page life. Introduce them with a brief attribution (\"as he puts it,\" or \"in his words,\") then let the quote do the work. Outside of quotes, the prose teaches — no attribution needed.\n- **Specific and grounded** — every technical claim needs concrete backing: plugin names, settings, frequencies, ratios, time values, routing decisions. \"Use some compression\" is worthless. \"OTT at 30% depth on the bus\" is useful.\n- **Match the energy of the source** — if the creator is hyped about a technique, let that land. If they're cautionary, make it feel urgent.\n- **Efficiency** — say it once, say it well. If a sentence doesn't teach something specific or make the next specific thing clearer, cut it.\n\n### Creator name usage — hard rule\n\nThe body sections are written as instructional content, not a biography. The creator's name appears in the **title** and **summary** for attribution — that's where the reader learns whose technique this is. The body sections then TEACH the technique directly, like a lesson book or a well-written blog post.\n\nThe creator's name should appear **at most once** in the entire body_sections content — and only when introducing a direct quote for the first time. Otherwise, the prose is instructive: \"do this\", \"set this to X\", \"route the signal through Y.\" Not \"he does this\", \"she sets this to X.\"\n\nBAD — third-person narration in every section:\n> **Section 1:** \"Keota solves this by creating dedicated analog modules...\"\n> **Section 2:** \"Keota uses Ableton's Remap plugin with a quantized staircase...\"\n> **Section 3:** \"Keota separates the modulation effect from the carrier...\"\n> **Section 4:** \"Keota compares options systematically...\"\n\nEach section re-introduces the creator as if the reader forgot whose page they're on. This reads like a Wikipedia article about a person, not a technique reference.\n\nGOOD — instructive voice, teaches the reader directly:\n> **Section 1:** \"The approach builds each harmonic as a separate parallel module with independent gain. Start with the 3rd harmonic, then optionally add the 5th, 6th, or 7th...\"\n> **Section 2:** \"Use Ableton's Remap with a quantized staircase curve to force any wavetable into discrete harmonic steps. Set up a harmonic control knob, map it to a quantized 8-step curve...\"\n> **Section 3:** \"To separate the modulation effect from the carrier signal, turn off the oscillator output and route through a mix module instead...\"\n> **Section 4:** \"When choosing waveforms for FM-style patches, compare the harmonic series wavetable against sync smooth sine...\"\n\nThe second version teaches a technique. The first version describes a person. Write the second version. Direct quotes naturally attribute themselves: \"as he puts it, '...'\" — that's the only place a pronoun reference to the creator is needed.\n\n## Body sections structure\n\nFrame sections around the problems the creator is solving or the situations a producer would recognize, not the tools being used.\n\nGood section names sound like something you'd say to a friend in the studio:\n- \"Why your bass disappears in mono\" / \"Getting the snare to cut without killing the vocal\" / \"The 90-200Hz gap that makes everything feel disconnected\" / \"Adding movement without losing the pocket\"\n\nBad section names sound like a textbook table of contents:\n- \"Overview\" / \"EQ Settings\" / \"Understanding Phase Plant signal flow\" / \"Compression Techniques\" / \"Final Thoughts\"\n\nThe test: would a producer ever search for this phrase when they're stuck? \"Why your bass disappears in mono\" — yes. \"Understanding Phase Plant signal flow\" — no, that's a manual heading, not a studio problem.\n\nEach section: 2-4 paragraphs of substantive prose, minimum 150 words per section. Flow logically within each section. **Merge thin topics aggressively** — if a section would only have 1 paragraph, fold it into the most related section. Never generate a section with fewer than 2 paragraphs.\n\n**Page minimum thresholds — hard rules:**\n- A page MUST have at least 3 sections and at least 400 words total. If the content can't fill this, it is too thin to be a standalone page.\n- If a category has fewer than 3 moments, DO NOT generate a standalone page for it. Instead, fold those moments into the most related page from another category.\n- NEVER generate a page with only 1 section. That's a paragraph, not a technique page.\n- Prefer fewer, richer pages over many thin ones. 3 substantial pages is always better than 6 stubs.\n\n## Plugin and detail rules\n\nEvery specific value needs its context — why this number, what problem it solves, when you'd change it.\n\nDon't just list \"attack +6dB\" — explain that the transient shaper is set to +6dB attack because the goal is to punch the initial click through without relying on compression (which adds sustain as a side effect). The value and the reasoning form a unit.\n\nInclude plugin names and settings only when the creator was teaching that setting — spending time on why they chose it. A plugin merely visible in their session belongs in the plugins list, not the prose.\n\nNever use vague fill: \"experiment with settings,\" \"adjust to taste,\" \"use your ears.\" If the creator gave a specific value, use it. If they gave a range, state the range.\n\n## Synthesis approach\n\nEach section follows a consistent rhythm that orients the reader before teaching them:\n\n**Orientation → Situation → Method → Implementation → Why it works**\n\n- **Orientation** (1-2 sentences): Briefly define or describe the concept being discussed. What IS this thing? This gives the reader a foothold before diving in. Example: \"Mid-side processing separates a stereo signal into its center (mid) and edges (side) components, letting you EQ or compress each independently.\"\n- **Situation** (1 sentence): When would a producer need this? Frame it as something they've experienced. Example: \"This becomes essential when a mix sounds wide in headphones but collapses to mush on a mono club system.\"\n- **Method** (the bulk): What to do and exactly how. Specific settings, routing, plugin choices. Instructive phrasing — \"Set the filter to 133Hz\" not \"he sets the filter to 133Hz.\"\n- **Why it works** (1-2 sentences): What problem this solves or what breaks if you skip it.\n\nThis structure prevents the prose from feeling like a giant run-on stream of techniques. The orientation sentence gives the reader context. The situation tells them why to care. Then the method teaches them what to do.\n\nExample of the full rhythm:\n> \"Parallel routing sends the dry signal and processed signal through separate paths before summing them at the output. This matters when you need to process the wet signal independently — adding EQ, compression, or distortion to just the reverb or chorus without touching the dry sound. Set up the effect at 100% wet on its own lane, then control the blend via channel gain rather than the plugin's internal mix knob. This gives you full processing access to the wet signal that an inline dry/wet knob can never provide.\"\n\nMerge moments that address the same problem. When the creator contradicts themselves across moments, explain the context for each approach — don't hide the contradiction, it's usually the most interesting part.\n\n## Section ordering — follow the workflow\n\n**This is the single most important structural rule.** The order of body_sections in your output MUST mirror the actual production workflow. This is non-negotiable.\n\nBefore you write, mentally assign each section a workflow stage number:\n- Stage 1: Conceptual framework / what the building blocks are\n- Stage 2: Building or shaping individual elements (the core construction)\n- Stage 3: Combining, processing, or refining the result (glue, bus processing, distortion)\n- Stage 4: Quality checks, validation, visual tests, mix-context adjustments\n\nThen output body_sections in that order. **A section about validating or checking the result can NEVER come before the sections about building the thing being checked.** A \"visual waveform validation\" section belongs at the END, not the beginning — the reader hasn't built anything to validate yet. A \"distortion as binding agent\" section comes AFTER the layers it's binding are explained.\n\nThe test is simple: read your section headings top to bottom and ask \"could a producer follow these steps in this exact sequence in their DAW?\" If the answer is no — if any section references, depends on, or validates something from a later section — your ordering is wrong. Fix it before outputting.\n\nWrong ordering (quality check before construction):\n1. \"Visual waveform validation\" ← checking a result that hasn't been built yet\n2. \"The three-layer framework\"\n3. \"Shaping the body tone\"\n4. \"Distortion as binding agent\"\n\nCorrect ordering (build → shape → combine → validate):\n1. \"The three-layer framework\"\n2. \"Shaping the body tone\"\n3. \"Distortion as binding agent\"\n4. \"Visual waveform validation\" ← now the reader knows what they're checking\n\n## Reader context\n\nYour reader could be a beginner or an expert. Write so both get value: use production terminology naturally (don't over-explain fundamentals), but when the creator explains a non-obvious concept in an illuminating way, include that explanation — it helps beginners and often contains nuance that experts appreciate too.\n\nThe page should be immediately scannable (clear section names, specific details prominent) for the expert who knows what they're looking for, and readable end-to-end for the learner who wants the full picture.\n\n## Summary requirements\n\nThe summary (2-3 sentences) is the hook. It opens with the most surprising or valuable thing — the one detail that makes a producer stop scrolling.\n\nBad summary: \"This page covers Keota's approach to harmonic synthesis using parallel modules, quantized remapping, and LFO modulation in Phase Plant.\"\nGood summary: \"Instead of relying on a single oscillator's harmonic series, he builds each harmonic as its own parallel module with independent gain — meaning you can automate the 3rd harmonic disappearing while the 5th swells in. The trick that makes it work: a quantized Remap curve that forces any wavetable into discrete harmonic steps.\"\n\nThe bad version describes what the page is about. The good version teaches you something in two sentences. Always write the good version. Use the creator's name once in the summary for attribution, then pronouns only.\n\n## Writing engagement\n\nThe page must be something a producer actually wants to read, not something they have to read:\n\n- **Open every section with a brief orientation, then get concrete** — start with 1-2 sentences that define or describe the concept so the reader has a foothold. Then immediately get specific. NEVER open with vague importance statements like \"A critical prerequisite...\" or \"Before building anything, you need to understand...\" — instead orient concisely then teach: \"Mid-side processing separates a stereo signal into center and edge components for independent processing. This matters when a mix sounds wide in headphones but collapses in mono — boost the side channel to widen, but only if actual stereo content exists there.\"\n- **Vary sentence rhythm** — a long technical sentence explaining a routing chain, then a short punchy one: \"That's the whole trick.\" Monotone paragraph structure kills engagement.\n- **Let the creator's personality drive the energy** — if they discovered something by accident, let that surprise come through. If they're warning you about something that burned them, make it feel urgent.\n- **End sections with something that sticks** — a direct quote, a warning, a key insight. Not \"This approach provides flexibility for future workflow adjustments.\" That's a nothing sentence. Instead: \"The modulation routing stays intact no matter what you add to the chain — that's the point.\"\n\n## Signal chains\n\nWhen the source moments describe a signal routing chain (oscillator → effects → processing → bus), represent it as a structured signal chain object. Signal chains are only included when the creator explicitly walks through routing — do not infer chains from casual plugin mentions.\n\nFormat signal chain steps to include the role of each stage, not just the plugin name:\n- Good: [\"Noise osc (Vital)\", \"Transient Shaper (Kilohearts, attack +6dB)\", \"EQ (Pro-Q 3, shelf -3dB @ 12kHz)\", \"Send → Trash 2 (tape algo, 35% wet)\"]\n- Bad: [\"Vital\", \"Kilohearts\", \"EQ\", \"Trash 2\"]\n\n## Source quality assessment\n\nAssess source_quality based on the nature of the input moments:\n- **structured**: Moments come from a planned tutorial with clear instructional flow. Most details are explicitly taught.\n- **mixed**: Some moments are well-structured, others are scattered or conversational. Common for track breakdowns.\n- **unstructured**: Moments are extracted from livestreams, Q&A sessions, or very informal content. Insights were scattered across a long session.\n\n## Input format\n\nThe creator name is provided in a <creator> tag. Key moments are provided inside <moments> tags as a JSON array, enriched with classification metadata (topic_category, topic_tags). All moments are from the same creator and related topic area. Use the creator name from the <creator> tag in the title, slug, and summary. Do NOT use the creator name repeatedly in body section prose — see the name usage rules above. Never invent or guess a creator name from transcript content.\n\n## Output format\n\nReturn a JSON object with a single key \"pages\" containing a list of synthesized pages. Most inputs should produce a **single page** — only split into multiple pages if the moments cover two genuinely unrelated techniques that a producer would never look up together (e.g., moments about both \"kick design\" and \"reverb automation\" that happen to share a category). When in doubt, keep it as one page. Every page must meet the minimum thresholds: at least 3 sections, at least 400 words, at least 3 source moments. If a split would create a page below these thresholds, don't split — merge into one richer page instead. When splitting, assign each moment to exactly one page via moment_indices — every input moment index must appear in exactly one page's array.\n\n```json\n{\n  \"pages\": [\n    {\n      \"title\": \"Snare Design by ExampleCreator\",\n      \"slug\": \"snare-design-examplecreator\",\n      \"topic_category\": \"Sound design\",\n      \"topic_tags\": [\"drums\", \"snare\", \"layering\", \"saturation\", \"transient shaping\"],\n      \"summary\": \"ExampleCreator builds snares as three independent layers — transient click, tonal body, and noise tail — each shaped by a transient shaper before any bus processing.

Defines `[N]` single-moment and `[N,M]` multi-moment format, placement rules (end of sentence before period), what to cite (factual claims only), and coverage goals.\n3. **Output format rewrite** — Replaced the JSON example with the v2 structure: `body_sections` is now a list of objects with `heading`, `content`, and `subsections`. Added `body_sections_format: \"v2\"` field. Example shows both flat sections (empty subsections array) and nested sections (with populated subsections). Citation markers appear inline in example prose.\n4. **Field rules update** — Changed body_sections description from \"Dict of section_name → prose\" to list-of-objects description. Added body_sections_format field rule.\n\nAll non-output-format sections (voice, tone, synthesis approach, section ordering, plugin rules, etc.) preserved unchanged. Prompt grew from 206 to 252 lines.\n\n## Verification\n\nRan the task-level verification command checking for `body_sections_format`, `Citation rules`, and `\"subsections\"` in the prompt file — all assertions passed. Additionally verified all 15 original section headings are preserved, the v2 JSON example contains both empty and populated subsections arrays, and the field rules section documents the new format.\n\n## Verification Evidence\n\n| # | Command | Exit Code | Verdict | Duration |\n|---|---------|-----------|---------|----------|\n| 1 | `python -c \"...assert 'body_sections_format' in t; assert 'Citation rules' in t...\"` | 0 | ✅ pass | 50ms |\n| 2 | `python3 -c \"...check all sections preserved, new content present...\"` | 0 | ✅ pass | 50ms |\n\n## Diagnostics\n\nThe prompt is a plain text file — diff against the `.bak` file to see exact changes: `diff prompts/stage5_synthesis.20260403_005044.bak prompts/stage5_synthesis.txt`\n\n## Deviations\n\nNone.\n\n## Known Issues\n\nNone.\n\n## Files Created/Modified\n\n- `prompts/stage5_synthesis.txt` — Rewrote output format section with v2 body_sections structure, added citation rules and H3 subsection guidance\n- `prompts/stage5_synthesis.20260403_005044.bak` — Pre-edit backup of prompt\n","path":"/home/aux/projects/content-to-kb-automator/.gsd/milestones/M014/slices/S01/tasks/T02-SUMMARY.md"}}],"api":"anthropic-messages","provider":"anthropic","model":"claude-opus-4-6","usage":{"input":1,"output":1006,"cacheRead":76973,"cacheWrite":1012,"totalTokens":78992,"cost":{"input":0.000005,"output":0.025150000000000002,"cacheRead":0.0384865,"cacheWrite":0.006325,"total":0.0699665}},"stopReason":"toolUse","timestamp":1775177534531}}
