name	session-report
description	Close a refactor step with a resumable session report. Use at the end of every step/PR of the clean-archi refactor so a fresh session can pick up exactly where this one left off. Updates the canonical docs/refactor/STATUS.md and appends a dated report under docs/refactor/sessions/.

Session report (close a refactor step)

Produce the artifacts that let a new session resume with zero context loss. Run this at the end of each step/PR, before stopping.

1. Gather the real state (don't guess)

export PATH="$HOME/.nvm/versions/node/v24.14.1/bin:$PATH"   # WSL: node not on PATH
date +%F                       # the report's date / filename prefix
git branch --show-current
git status --short
corepack pnpm refactor:preflight   # current knip + jscpd numbers

Compare the knip/jscpd numbers against the baseline in docs/refactor/STATUS.md. A regression (more dead code / duplication than baseline) must be called out — and ideally fixed before reporting done.

Mutation testing locally (Stryker). If the step touched the mutated scope (src/domain/cpc/** or src/libs/pixsaur-color/src/{histogram,space,utils,metric}/** — see stryker.config.json), run pnpm test:mutation and record the score in the Guardrail section. The CI post-merge run (.github/workflows/mutation.yml) is a backstop, not the gate — surviving mutants must be caught before the PR while the code is fresh. Skip only when the step touched no mutated file (say so). Never raise thresholds.break to hide surviving mutants — harden the tests first (ratchet). See docs/refactor/PLAN-quality-gates-from-loupe.md for the tracked mutation-debt backlog.

2. Append a dated session report

• Copy docs/refactor/sessions/_TEMPLATE.md to docs/refactor/sessions/<YYYY-MM-DD>-<slug>.md (slug = the step, e.g. pr1-export-ports). Never overwrite an existing report — history is append-only.
• Fill every section honestly: Done, Not done / remaining, Decisions, Guardrail status (with the numbers from step 1), State to resume from.
• "State to resume from" must name the SINGLE next action and any gotchas / half-done edits.

3. Update the canonical STATUS

Edit docs/refactor/STATUS.md:

• Move the roadmap table row(s) to ✅ / update status.
• Update "Where we are" (branch, current step, next step).
• If a detector number genuinely improved, lower the ratchet baseline (never raise it to hide a regression).

4. Keep memory in sync (optional, if the plan shifted)

If a cross-session decision changed, update the refactor-clean-archi-plan memory note. Don't duplicate the whole report there — just the durable decision.

Output

End with a 3-line summary to the user: what's done, the next action, and the report path.
