feat(agent): extend pest-parallel-debugger с quirk 77 (unique-key collision)
Applied 4 edits per quirk-77 plan Task 3:
- Edit 3.1: добавлен Quirk 77 entry в known-quirks section (between Quirk 73 и NB line)
- Edit 3.2: добавлена Hypothesis 4 quirk 77 в diagnostic pipeline (renumber «other» к H5)
- Edit 3.3: обновлён output format template (+Hypothesis 4 row + extended Conclusion options)
- Edit 3.4: обновлён description frontmatter (+quirk 77 classification (d))
Quirk 77: Pest --parallel deterministic unique-key collision на projects(tenant_id, name)
в ProjectBulkActionsTest::rejects_bulk_when_scope_filter_captures_more_than_500_projects.
Evidence (Task 8 baseline check):
- db/schema.sql:836 UNIQUE (tenant_id, name)
- app/database/factories/ProjectFactory.php:23 fake()->words(3, true)
- app/tests/Pest.php:18 // ->use(RefreshDatabase::class)
- app/tests/Feature/Api/ProjectBulkActionsTest.php:194-206 (501-project bulk)
- 2× --parallel runs failed 738/742; sequential isolation 14/14 ✅
- NOT regression from feat/claude-automation (f454e95 audit-2 zero PHP)
Root cause partial: collision matches birthday paradox (~12.5%), но
deterministic-in-parallel vs sequential suggests worker state sharing
(shared Faker seed via PHP global? Eloquent factory caching?). Full RCA pending.
Mitigation: known parallel-only flake; sequential always passes.
Long-term fix candidates documented в quirk entry.
NB: project-local subagent auto-discovery может требовать session restart.
Verification: markdownlint 0 errors, gitleaks no leaks, +13/-3 lines.
