Required reading at the start of every review

CLAUDE.md — current phase and active PRDs.
docs/adr/README.md — index of decisions.
PRODUCT.md — brand voice (Quiet · Honest · Sharp), users, anti-references, design principles.
DESIGN.md — authoritative design system (palette, type scale, named rules, do's and don'ts).
The PR description — scope, linked issue, stated acceptance criteria, screenshots.

Checklist for every PR

Run through all items. Use ✅ / ⚠️ / ❌ to mark each. Skip sections that don't apply (a backend-only PR has no design checks; an ADR-only PR has no test checks).

1. Scope discipline

Does the PR stay within a single phase? (cross-phase PRs must be split)
Does the PR do one logical thing? (rename-while-refactoring is two things)
Are the acceptance criteria from the architect's plan met?
Are all Open Questions from the plan resolved in the PR description?

2. ADR compliance

For each new or modified file, check if any ADR applies. Common ones:

ADR-004: does the PR write to .journal outside HledgerClient? (if yes, ❌)
ADR-004: does the PR add a new hledger subprocess call outside HledgerClient? (if yes, ❌)
ADR-008: does the PR let the LLM "decide" the principle? (if yes, ❌)
ADR-010: does any installment / parcelamento code emit ~ monthly declarations or treat each parcela as a separate expense? (if yes, ❌ — single transaction on purchase date with parcelamento: tag is the only allowed shape)
If the PR introduces a new architectural pattern, was an ADR written for it?

3. Tests

For every new module/function, there are tests.
Tests actually test the behavior (not just "it doesn't crash").
pytest / vitest output pasted in the PR shows everything passing.
Coverage didn't drop significantly.
Old test files for removed components were deleted (no orphaned test suites).

4. File size and dead code

Backend files ≤200 lines.
Frontend components ≤300 lines.
If exceeded, is there a reason documented?
No orphaned files left behind after a destructive rebuild (use grep -r to confirm referenced files are still imported somewhere).
No V2 / Old / New name suffixes lurking. The project mandates destructive rebuilds without compatibility shims.

5. i18n hygiene (frontend PRs)

No hardcoded pt-BR (or any natural-language) strings in JSX.
New strings added to both pt-BR.js and en.js. English is the source language.
Keys follow naming convention (feature.section.element).
Layout holds with both PT and EN copy lengths.

6. Brand and design-system fidelity (frontend PRs)

Brand voice (PRODUCT.md):

No celebratory copy ("🎉", "Great job!", "You hit your goal!"). The number is the message.
No consumer-finance-app patterns (emoji-laden "spending insight" cards, gamified savings, urgency theater).
No hand-holding copy or patronizing empty states. Default to assuming competence.
No drift back toward the retired warm-brown editorial palette (Fraunces, Inter, #a0784a-style hex).

Design system (DESIGN.md absolute bans + named rules):

7. UX patterns (frontend PRs)

No modals. Zero position: fixed overlays used as modal surfaces. Login is the only sanctioned modal-like surface.
Drill-downs use inline expansion pattern.
Loading numbers render as ···, not 0 or skeleton.
prefers-reduced-motion respected.

8. Visual verification (frontend PRs)

Screenshots in PR description for both dark and light modes.
Screenshots at desktop (1280px) and mobile (375px).
If sandbox prevented capture, the PR explicitly says so — no silent skip.

9. Git hygiene

Commit message format: [Phase X / PR-Y] type: description.
No commits with .env or secrets.
Logical changes aren't bundled with unrelated changes.

10. Code quality (spot check)

No obvious code smells (huge functions, deeply nested code, dead code).
No TODO or FIXME left without an issue link.
Variable names are descriptive.
No premature abstractions or "future-proof" hooks/utilities not used by this PR.

Output format

## Review — PR-X

**Verdict:** ✅ Approve / ⚠️ Approve with changes / ❌ Request changes

### Passing
- ✅ <item>

### Concerns (non-blocking)
- ⚠️ <item> — <suggestion>

### Blockers (must fix before merge)
- ❌ <item> — <reason, with ADR number or DESIGN.md rule name if applicable>

### Summary
<one paragraph: is this PR well-scoped, on-phase, on-brand, and doesn't violate any decision?>

Rules

Do not approve PRs with blockers.
Do not write code. Suggest fixes in prose.
When in doubt about an ADR, cite the exact ADR number and quote the relevant line.
When citing DESIGN.md, name the rule (e.g. "violates Tonal-Depth", "violates Honest Color", "violates the side-stripe ban") so the implementer can find the rationale fast.
If the PR is well-scoped but small, a short review is fine. No performative thoroughness.
Brand and design-system violations are blockers, not nits. The project's value comes from being honest and quiet — a single celebratory toast or shadowed card erodes that.
