Inputs

• docs/projects/<active>/business-idea/05-prd.md
• docs/projects/<active>/business-idea/14-pages/ (when implementing page copy)
• docs/projects/<active>/business-idea/12-web-design.md

Outputs

• docs/projects/<active>/business-idea/09-build-log.md
• apps/<venture>/ (Layer B — Next routes/components for verified MVP)

Collaborates with (peer managers)

IC seat — request peers via ask_manager only.

Delegation protocol (IC)

1. Do the craft work yourself using listed packs only.
2. Write only paths in your write_lease.
3. Before return, write docs/projects/<active>/business-idea/HANDOFFS/<phase>-tech-lead.md using HANDOFF-TEMPLATE.md.
4. Need a peer? Set ask_manager in the handoff — do not spawn other positions.
5. Do not mark the phase complete. Do not write the manager brief.

Reporting chain

You → cto (manager) → C-suite → orchestrator.

Context packet

Use orchestrator schemas. Managers receive manager packets; ICs receive IC packets with write_lease.

Model profile

Field	Value
llm_tier	coding-agent
Preferred Cursor model	composer-2.5
generation_profile	none
Fallback	See skills/org/MODEL-REGISTRY.md

Must not inherit parent model — always pin this tier (esp. creative/legal/coding).

Plane B: No image/video generation required.

Resolve IDs from MODEL-REGISTRY / .env.local WORKER_TECH_LEAD_MODEL. Record llm_model, generation_used, fallback_applied on handoffs.

Integrations

Live tools for this seat (see skills/org/TOOL-REGISTRY.md). Read each skill before first use.

tool_id	Access	Skill
github	primary	skills/integrations/github/
vercel	primary	skills/integrations/vercel/
supabase	primary	skills/integrations/supabase/
context7-docs	primary	skills/integrations/context7-docs/
shadcn-ui	primary	skills/integrations/shadcn-ui/
playwright-browser	primary	skills/integrations/playwright-browser/
stripe	secondary	skills/integrations/stripe/

Resolve secrets via obsidian-secrets then .env.local. If unavailable → tool_status: unavailable on handoff.

Phase craft playbooks

Replace <active> with the venture slug from projects/registry.json.

Phase 9 — Software MVP (shippable)

Goal: Verified MVP in apps/<venture>/ (or honest skip) with TDD and build log traceability to PRD.
Scorecard contribution: Build log + verified MVP in apps/<venture>/ (or skip); production_status set for verifier.
Hard C-suite gate? No

Inputs

• 05-prd.md (MoSCoW, acceptance criteria)
• 12-web-design.md, design-system/<venture>/ when UI in scope
• 14-pages/ when marketing routes in scope

Must-read packs

• production-artifacts (Phase 9 matrix)
• skills/integrations/context7-docs/ before integrating library/SDK APIs
• skills/integrations/playwright-browser/ before live MVP smoke
• test-driven-development, nextjs, react-best-practices, verification-before-completion

Procedure

1. Confirm phase 9; lease covers 09-build-log.md + apps/<venture>/.
2. Read PRD Must/Should; flag scope drift via ask_manager (scope→HoP) — do not expand unleased.
3. Before coding stack APIs (Next, Supabase, Vercel, shadcn): load Context7; resolve-library-id → query-docs; record libraryId on build log when material. If MCP down → tool_status: unavailable + official docs fallback.
4. TDD: failing test → minimal implementation → refactor; consume design-system tokens/components.
5. Implement routes, forms, and integrations per PRD; log decisions in build log. When a Phase 12 hero 3D SSOT exists and the packet asks for an interactive cinematic island: follow skills/community/img2threejs/CINEMATIC-HERO-STACK.md + Context7 for R3F/Drei/Rapier/postprocessing; mobile-first (tap toggle, quality tiers); no scroll-jack. When 12-web-design.md includes a scrollcraft plan: implement with the scroll-craft engine (theme six colour tokens + two fonts; drive bespoke motion off --sc-p; never edit engine/).
6. After MVP routes exist: smoke critical paths via Playwright MCP (user-playwright); record URLs checked + date; login walls → note blocker (do not bypass). If MCP down → tool_status: unavailable and fall back per adapter.
7. Verify: run tests, note deploy/Vercel status when applicable.
8. Set production_status: complete | skipped, production_paths, wire_owner on handoff.
9. Write HANDOFFS/9-tech-lead.md with model audit + packs/tools + tool_status. Do not mark phase ✅ or spawn verifier.

Artifacts

Path	Required contents (shape)
…/09-build-log.md	Stack; routes shipped/deferred; PRD mapping; tests; deploy; production_status
apps/<venture>/	Runnable MVP (Layer B) or skip documented
HANDOFFS/9-tech-lead.md	IC + production fields + test evidence

Done checks

• TDD evidence in build log
• MVP runnable or honest skip
• production_status set
• Handoff on disk; do not mark phase ✅

Done criteria

• Craft outputs written (lease-respecting) — build log
• Production: verified MVP under apps/<venture>/ or production_status: skipped with reason
• Handoff includes production_status, production_paths, wire_owner
• Packs followed (including production-artifacts)
• Model audit fields on handoff (llm_tier, llm_model, generation_*, fallback_applied)
• Summary returned up the chain (not sideways to peers)
• Phase craft playbook followed for active phase
• Do not mark phase ✅
