chore(ci): skip perf and commits gates on Renovate-authored PRs (#23)
## 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`.

Architectural Decision Records

This project records architecturally-significant decisions as ADRs in the MADR 4.0.0 format. References: adr.github.io.

Why ADRs

ADRs capture the why behind a decision — context, drivers, options considered, trade-offs accepted — at the moment the decision is made. They make architecture reviewable, onboarding faster, and prevent the same debate from being re-litigated later.

Conventions

  • Format: MADR 4.0.0. Start from template.md.
  • Filename: NNNN-kebab-case-title.md, e.g. 0007-adopt-tailwind-for-design-tokens.md.
  • Numbering: globally sequential 4-digit prefix. Numbers never reset, never get reused — even when an ADR is superseded or deprecated.
  • Layout: flat folder. ADRs are not nested into category subfolders; topical organization happens via tags.
  • Tags: every ADR carries a tags: array in the MADR frontmatter, drawn from the tag vocabulary below. An ADR may carry several tags. Propose new tags (or renames) in the same PR that needs them; never invent ad-hoc tags inline.
  • Status lifecycle: proposedaccepted → optionally deprecated or superseded by [ADR-NNNN](NNNN-other.md). Update the YAML frontmatter; never delete an ADR.
  • Index maintenance: every ADR addition or status change must update the Index below in the same commit.

When to write an ADR

Write one whenever a development decision is non-trivial: tool or library choice, framework pattern, security control, perf budget, a11y target, naming convention, deprecation, breaking change, or any choice that future contributors would benefit from understanding the why of.

Tag vocabulary

The vocabulary below is the source of truth. It is intentionally coarse — propose extensions only when an existing tag genuinely doesn't fit, and avoid overly narrow tags.

Tag Scope
frontend UI, Angular, components, design system, client-side state
backend API, BFF, server-side services
security AuthN, AuthZ, sessions, CSP, dependency scanning, secret management
performance Perf budgets, caching, bundle size, Lighthouse
accessibility WCAG, a11y testing, keyboard, ARIA, contrast
infrastructure CI/CD, hosting, deployment, runtime
observability Logs, metrics, traces, correlation IDs, monitoring
data Persistence, schemas, migrations, data flow
process Team conventions, workflows, repo policy

Status: starter vocabulary, to be refined as ADRs accumulate. Update this table whenever a tag is added, renamed, or retired.

Index

ADRs are listed in numerical order. To slice by topic, filter on the Tags column.
