docs(pdftract-3a310): add coordinator verification note

Document status: coordinator cannot close because pdftract-1lp2 (Profile Authoring epic) is open.

Missing for epic completion:
- Fixtures: bank_statement (0/5), contract (0/5), form (0/5), receipt (2/5)
- expected-output.json: 0/9
- Regression tests: 0/9

+# Phase 7.10 Coordinator Verification Note
+
+**Bead ID:** pdftract-3a310
+**Date:** 2026-05-31
+**Commit:** 80dbf0f (feat(profiles): add profile infrastructure and initial fixtures)
+
+## Status: CANNOT CLOSE - Dependent epic incomplete
+
+The coordinator `pdftract-3a310` cannot be closed because its dependent epic `pdftract-1lp2` (Profile Authoring) is still **open**.
+
+## Dependency Chain
+
+```
+pdftract-3a310 (Phase 7.10 coordinator)
+├── pdftract-3zhf (Phase 7.2 coordinator) - CLOSED ✓
+├── pdftract-2mw6 (Phase 7.4 coordinator) - CLOSED ✓
+└── pdftract-1lp2 (Profile Authoring epic) - OPEN ✗
+```
+
+## What Was Completed (This Session)
+
+### Profile Infrastructure Code
+Committed in 80dbf0f:
+- `crates/pdftract-core/src/profiles/apply_profile.rs` - Profile application logic
+- `crates/pdftract-core/src/profiles/extraction.rs` - Extraction override handling
+- `crates/pdftract-core/src/profiles/extraction_loader.rs` - Extraction option deserialization
+- `crates/pdftract-core/src/profiles/field_extractor.rs` - Field DSL evaluator
+- `crates/pdftract-core/src/profiles/match_eval.rs` - Match DSL evaluator
+- `crates/pdftract-cli/src/profiles_cmd.rs` - profiles subcommand implementation
+- Updated `crates/pdftract-core/src/profiles/mod.rs` - Module exports
+
+### Built-in Profile YAMLs (9/9 complete)
+All 9 profiles exist at `profiles/builtin/<name>/profile.yaml`:
+- invoice, receipt, contract, scientific_paper, slide_deck
+- form, bank_statement, legal_filing, book_chapter
+
+### Profile READMEs (9/9 complete)
+All 9 profiles have README.md at `profiles/builtin/<name>/README.md`
+
+### Classifier Corpus (exists)
+`tests/fixtures/classifier/` contains:
+- contract, invoice, misc, scientific_paper directories
+- MANIFEST.tsv
+- README.md
+
+### Fixtures Added (partial)
+- invoice: 50 PDF fixtures ✓
+- receipt: 2 PDF fixtures (needs 3 more)
+
+## What Remains for `pdftract-1lp2` (Profile Authoring Epic)
+
+### Missing Fixtures (per acceptance criteria: >= 5 per profile)
+- bank_statement: 0/5 fixtures
+- contract: 0/5 fixtures
+- form: 0/5 fixtures
+- receipt: 2/5 fixtures (needs 3 more)
+
+### Missing Expected Output Files (0/9)
+- `tests/fixtures/profiles/<name>/expected-output.json` does not exist for any profile
+- These files contain the canonical `metadata.profile_fields` expected values for each fixture
+
+### Missing Regression Tests (0/9)
+- `tests/profiles/test_<name>.rs` does not exist for any profile
+- Should run each fixture through `extract --profile <name>` and assert against expected-output.json
+
+## Acceptance Criteria Status
+
+For `pdftract-3a310` coordinator:
+
+| Criterion | Status |
+|-----------|--------|
+| All Phase 7.10 child task beads closed | ❌ BLOCKED - `pdftract-1lp2` is open |
+| Acrobat sample invoice classified > 0.8 confidence | ⚠️ NOT TESTED - needs classifier corpus run |
+| Invoice field extraction >= 90% accuracy | ⚠️ NOT TESTED - needs expected-output.json + regression test |
+| Custom profile with priority 100 overrides built-ins | ⚠️ NOT TESTED |
+| Malformed regex profile rejected by validate | ⚠️ NOT TESTED |
+| profile_fields.total: null when not found | ⚠️ NOT TESTED |
+| Hot-reload picks up new YAML on next request | ⚠️ NOT TESTED |
+| User profile shadowing shown in list | ⚠️ NOT TESTED |
+| Built-in invoice profile >= 90% field accuracy | ⚠️ NOT TESTED |
+| Field extraction adds < 5% to per-document time | ⚠️ NOT TESTED |
+| 9 built-in profiles ship with >= 5 fixtures each | ❌ FAIL - bank_statement, contract, form have 0; receipt has 2 |
+| Built-in profile YAML compiled via include_str! | ⚠️ NOT VERIFIED |
+
+## Next Steps
+
+To close `pdftract-3a310`, first close `pdftract-1lp2` (Profile Authoring epic):
+
+1. Add missing fixtures (15 total: bank_statement 5, contract 5, form 5, receipt 3)
+2. Generate expected-output.json for each profile's fixtures
+3. Write regression tests at `tests/profiles/test_<name>.rs`
+4. Run classifier corpus validation to verify >= 90% accuracy
+5. Verify all acceptance criteria
