## Summary
Renovate's dep-bump PRs run the full pipeline today (`check`, `scan`, `commits`, `perf`, `a11y`). Two of those gates have near-zero signal on a typical bump and dominate the wall-clock cost:
- **`perf`** — Lighthouse build + 3-iteration median across the critical-routes list. 3-5 min per PR for a metric that is essentially zero on a patch/minor dep bump (the SPA today serves the static placeholder; even with real routes a typical bump stays inside the median noise floor).
- **`commits`** — re-validates commit messages that Renovate generates from a Conventional-Commits-conformant template. Tautological.
Skip both when the PR author is the `apf-portal-bot` Gitea user. The `push` event on `main` still runs the full pipeline post-merge, so any regression caught by `perf` is detected seconds after merge — fast enough to revert.
Net result: Renovate PRs run `check + scan + a11y` only, ≈ 4-5 min faster per PR.
## ADR amendment
ADR-0017 is amended in the same change:
- "Where Lighthouse CI runs" table now distinguishes human PR / bot PR / push to main / scheduled / local.
- New "Pre-merge gating policy: human PRs vs bot PRs" subsection records the rationale and the human-takeover edge case.
- §Confirmation entry for `perf` is reworded to reflect the conditional gate.
## Test plan
- [ ] After merge, the next Renovate-triggered PR (auto-rebase or new bump) shows only `check`, `scan`, `a11y` queued — no `perf`, no `commits`.
- [ ] A human-opened PR (e.g. this one) still queues all 5 gates.
- [ ] On `push` to `main` post-merge, the full pipeline runs including `perf`.
