Roadmap Tier 1 + 2: CI, templates, CONTRIBUTING, CHANGELOG, evaluator-pass skill, new-source-brief.sh, PUBLISHABLE tier, pre-commit

[hnshah]

Ships 11 of the 13 Tier 1 + Tier 2 items from the roadmap discussion. Two items (real-object runs) need objects from you and are flagged at the bottom.

What's in

Tier 1 (high leverage, small effort)

• .github/workflows/check.yml — runs doctor.sh and slop-check.sh on every push and PR. First thing a public-repo visitor checks is whether CI is green.
• .github/PULL_REQUEST_TEMPLATE.md — matches the repo's actual PR rhythm (summary / what changed / verification / test plan).
• .github/ISSUE_TEMPLATE/ — three templates: method-feedback (I used PageKit), bug (tooling misbehaving), method-proposal (change the chain).
• CONTRIBUTING.md — four shapes of contribution, required checks, what bad contribution looks like. Cites the run → evaluator-pass → punch list → method change loop as the method-change pattern.
• README.md — sharper public-facing hero. Leads with the core principle and a direct link to runs/vegan-dog-food-verdel/ as the canonical worked example.
• v0.1.0 tag and GitHub release will be pushed after this PR merges.

Tier 2 (high leverage, medium effort)

• .claude/agents/pagekit-evaluator-pass.md — read-only subagent for the adversarial evaluator pass. Parallel to the existing pagekit-claim-checker subagent.
• .claude/skills/pagekit-evaluator-pass/SKILL.md — user-invocable skill wrapper. Delegates to the subagent.
• scripts/new-source-brief.sh — scaffolds a single source brief (wedge/mechanism/proof/comparison) on demand. Auto-numbered to slot into runs/<name>/sources/.
• scripts/run-check.sh — new PUBLISHABLE tier above FULLY LOGGED. Requires claim-check.md filled in (not placeholder), first-page-draft.md filled in, and slop-check clean on the drafts. runs/vegan-dog-food-verdel/ now classifies as PUBLISHABLE; empty scaffolds classify as FULLY LOGGED with a clear punch list.
• .pre-commit-config.yaml — local enforcement of slop-check and doctor. Opt-in (install with pre-commit install).
• CHANGELOG.md — seeded with v0.1.0 (the current merged state, summarizing PRs Fix canonical chain drift and homepage defaults across the repo #1–Clean-slate finish + public-readiness: remove high-trust test, add LICENSE + .gitignore #8) and [Unreleased] for this PR's additions.

Doctor updates

• Includes the new subagent, the new skill, and new-source-brief.sh in its checks.

Deferred, flagged for you

• T1 Vegan dog food second pass: fully logged, non-homepage, hard claim-check + repo fixes it surfaced #2 + T2 Roadmap Tier 1 + 2: CI, templates, CONTRIBUTING, CHANGELOG, evaluator-pass skill, new-source-brief.sh, PUBLISHABLE tier, pre-commit #9: real-object runs (non-fictional). Need objects from you to execute. One SaaS product + one B2C physical product + one other object would give us a proper 4-category validation set (with Verdel).

Verification

• CI on this PR passes (doctor.sh + slop-check.sh)
• bash scripts/run-check.sh runs/vegan-dog-food-verdel → PUBLISHABLE, exit 0
• bash scripts/new-run.sh _verify && bash scripts/run-check.sh runs/_verify → FULLY LOGGED (not PUBLISHABLE) with clear upgrade path
• bash scripts/new-run.sh _sbtest && bash scripts/new-source-brief.sh _sbtest mechanism scaffolds runs/_sbtest/sources/02-mechanism-brief.md
• Skim CONTRIBUTING.md, CHANGELOG.md, and the new PR + issue templates

Next move after merge

1. Tag v0.1.0 and push the tag (I'll handle this from my side once merged).
2. Real-object run(s) — tell me the objects and I'll run /pagekit.
