Slice 11 / Phase 4 (v2): Build Log batch (eps 2–8) + launch acceptance

[tkowalczyk]

Parent PRD

#12

What to build

Scale the proven workflow from #22 across the rest of the slate. Ship episodes 2–8 to hit the 8-article launch floor; episodes 9–10 are stretch additions if cadence allows.

Each article follows the same recipe: extraction script → LLM draft → author curation → disclosure-policy self-review → merge. Articles ship in batches (one PR per article or per small group), preserving review-ability.

Launch slate (Episode 1 ships in #22; this issue covers 2–8 plus stretch):

2. Building the warehouse: storage choice and category coverage
3. Why we excluded sports
4. The first failed paper replication — structural divergence finding
5. From peak-fill anchor to external calendar
6. Adding cluster detection and counterparty HHI
7. Performance lessons: when to measure, when to extrapolate
8. Long-running scripts and the heartbeat discipline
9. (stretch) The open-book P&L: designing statements for the project itself
10. (stretch) Schema-as-contract: how the LP forced a producer/consumer split

Once the floor is hit, run the launch acceptance battery: LLM install-snippet recheck, staging walkthrough, sign-off.

See plans/slice-11-build-log.md Phase 4 for full details.

Acceptance criteria

• At least 8 Build Log articles are live, episode-numbered consecutively from 1
• Every article covers a distinct phase of poly-track's evolution (no duplicates, no overlapping scope)
• Every article passes the author's disclosure-policy self-review and the result is recorded (commit message or PR description)
• No published article contains a wallet ID, an alert payload, or content that could front-run an open position
• LLM install-snippet manual recheck: paste the homepage install snippet into Claude and ChatGPT, ask "summarize ogsfrompoly's methodology evolution" — both produce substantively correct answers derived from article content alone
• Staging walkthrough of /about, /articles/, and a representative article confirms typography, hero rendering, embedded snippet blocks, and feed pickup all behave as designed
• Cloudflare Web Analytics confirms hits are recorded for /about, /articles/, and individual article URLs (plus their .md counterparts) within the documented latency
• "Slice 11 launched" sign-off recorded in the repo (commit, PR description, or PRD Phase 5 / Slice 11 (v2): Build Log article series + about page #12 closing comment)
• pnpm types && pnpm test && pnpm lint && pnpm knip all pass in CI

Blocked by

• Blocked by Slice 11 / Phase 2 (v2): /about page — bio, photo, contact, public links #21 (/about must exist for the staging walkthrough)
• Blocked by Slice 11 / Phase 3 (v2): Workflow tracer — extraction script + Build Log Episode 1 #22 (Episode 1 + extraction script must exist; this issue scales the proven workflow)
