docs: sync AGENTS.md and CLAUDE.md with undocumented test files

[slittycode]

Summary

Audit of documentation vs. actual codebase found 10 test files in apps/backend/tests/ with no entry in either CLAUDE.md or apps/backend/AGENTS.md, plus 2 file-map gaps in apps/ui/AGENTS.md. All documented files and modules were confirmed to exist — no stale references to removed code were found.

apps/backend/AGENTS.md — added to File Map:

• test_audio_fixture.py / test_audio_fixture_smoke.py — WAV fixture helpers (no model load)
• test_bootstrap_scripts.py — bin/asa install/bootstrap script contracts
• test_cleanup.py — utils/cleanup.py artifact-cleanup helpers
• test_genre_check.py — scripts/genre_check.py
• test_phase1_evaluation_transcription.py — Layer 2 transcription evaluation harness path
• test_phase2_grammar_fix.py — Phase 2 gerund-fix post-process in server_phase2.py
• test_phase2_prompt_catalog.py — prompt examples vs. Live 12 catalogue
• test_root_dev_script.py — root scripts/dev.sh env-loading behavior
• test_root_e2e_script.py — root test-e2e{,-integration}.sh script contracts
• test_separation_ab.py — separation_ab.py SI-SDR aggregation math
• Added "Covered by tests/test_cleanup.py" to the utils/cleanup.py entry
• Added "Covered by tests/test_separation_ab.py" to the separation_ab.py entry

apps/ui/AGENTS.md — file-map gaps:

• src/services/midi/ was missing types.ts
• src/services/sessionMusician/ was missing index.ts

CLAUDE.md — added inline test references at the relevant callout sites:

• Item 17 (utils/cleanup.py): tests/test_cleanup.py
• Item 16 (eval harnesses): tests/test_phase1_evaluation_transcription.py
• Phase 2 block: tests/test_phase2_grammar_fix.py, tests/test_phase2_prompt_catalog.py
• Scripts section: test_root_dev_script.py, test_root_e2e_script.py, test_bootstrap_scripts.py, test_genre_check.py, test_separation_ab.py

Test plan

• No code changed — documentation-only PR
• All referenced test files confirmed to exist in apps/backend/tests/
• All referenced service files confirmed to exist in apps/ui/src/services/

Verdict: APPROVE

Summary

Pure documentation sync — adds 10 previously undocumented backend test files to apps/backend/AGENTS.md, backfills inline test references in CLAUDE.md, and plugs two file-map gaps in apps/ui/AGENTS.md (midi/types.ts, sessionMusician/index.ts). Every single referenced file was verified to exist in the repo. No code touched, no contracts changed.

Findings

None.

Test results

CI still running at review time, but immaterial — no source files changed. Docs-only diffs cannot break tests.

Phase boundary check

Clean. No phase code touched.
