Assemble the ship record

A shippable lab artifact includes: how to run it, the metric result (gh pr view shows base=main, head=improve-evaluation, and check summary), the failure you can still reproduce (pushing straight to main, or opening a PR with failing checks ignored), the security gate for force-pushing rewritten history on a shared branch or leaking tokens in PR body, and a rollback note. The user decision it supports remains: propose a reviewed evaluation change for merge only after checks pass.

Freeze the evidence

printf 'proved: PR+checks visible\nunproved: production impact\nrollback: revert merge commit\n'

Expected evidence: GitHub ship note. Store this beside the fixture version so scores remain meaningful after content changes in github-basics.

Explain limits without apology

State operating limits for the evaluation pull request in plain language: fixture size, offline vs live dependencies, and what would require a new eval set. Shipping github-basics is honest scoping, not maximal confidence language.

Lab notebook: proved vs unproved

Fill this table in your notes for the evaluation pull request:

  • Proved on feature branch improve-evaluation with one commit: …
  • Unproved beyond the fixture: …
  • Metric that blocks release: gh pr view shows base=main, head=improve-evaluation, and check summary
  • Failure still reproducible: pushing straight to main, or opening a PR with failing checks ignored
  • Security gate: force-pushing rewritten history on a shared branch or leaking tokens in PR body
  • Rollback: …

Ship the narrative only when the unproved list is honest. Reviewers trust narrow claims that support propose a reviewed evaluation change for merge only after checks pass more than maximal language that collapses under the first production oddity.

Worked judgment

Hand your ship note to a peer and ask them to recreate a proved/unproved ship note with rollback without watching you type. If they cannot, your evidence is still tribal knowledge. Tighten the run command and the metric line until a stranger can validate the evaluation pull request against feature branch improve-evaluation with one commit.

Why this stage matters for the evaluation pull request

At the mastery and shipping stage for github-basics, the job is narrower than finishing a product demo. You are creating one progressive evidence piece about feature branch improve-evaluation with one commit that later pages inherit without redefining success. Keep that fixture small enough to inspect by hand, keep outputs copy-pasteable as text, and refuse to narrate this baseline as if it were a production SLA: branch protection / required checks listed before opening the PR.

For this page specifically, success looks like a proved/unproved ship note with rollback while still centering the user decision to propose a reviewed evaluation change for merge only after checks pass. If you cannot point to a file, command, or assertion that proves that for the evaluation pull request, stay on this page instead of advancing.

Why this matters

List two things this chapter proved on the fixture and two things it did not prove about the evaluation pull request. If you cannot name the gaps, you are not ready to ship the narrative—even if the code runs.

Page assessment

Answer from memory. Completion is saved from this evidence, not from opening the next page.

1. Are proved and unproved lists both non-empty?
2. Is rollback concrete (command or version pin)?
3. Would a stranger reproduce the metric on the fixture?
4. Does the note still center the decision: propose a reviewed evaluation change for merge only after checks pass?
