Summary

1. Decomposed skills/poteto-mode/scripts/orch/store.ts (previously 1,677 lines) into cohesive domain submodules:
   • types.ts (312 lines): Domain models, interfaces, errors, and validator parsers.
   • lock.ts (84 lines): Process lock acquisition, stale lock detection via PID lifecycle, and safe release.
   • frontier.ts (299 lines): Multi-forge PR queries (gh and origin), loop detection, and linear chain validation.
   • report.ts (230 lines): Status summaries, diff detection, and Markdown status reporting.
   • tables.ts (383 lines): Atomic TSV and Markdown table storage operations.
   • store.ts (465 lines): Store orchestrator composing submodules and providing full backwards compatibility re-exports.
2. Verified all production modules in orch/ are strictly under 500 lines.
3. Added boundary test in orch.test.ts verifying module line count invariant.
4. Restamped durable evidence receipts in .audit/evidence/ for updated skills_tree_hash (a6e1c952...), achieving 100% matrix freshness.
5. All 102 bun tests, pytest suites, and doctor across all 6 harnesses pass cleanly.

1. Modularity, Line Count, and Invariants

The previous monolithic skills/poteto-mode/scripts/orch/store.ts (1,677 lines) has been decomposed into 6 cohesive domain submodules. Every decomposed production module is strictly under 500 lines:

Module	Purpose	Line Count	Status (< 500 lines)
types.ts	Domain models, interfaces, errors, validator parsers	312	PASS
lock.ts	PID lifecycle, lock acquisition, stale lock recovery	84	PASS
frontier.ts	Multi-forge PR queries (gh, origin), chain loop detection	299	PASS
report.ts	Status summaries, diff detection, Markdown status formatting	230	PASS
tables.ts	Atomic TSV and Markdown table storage operations	383	PASS
store.ts	Store orchestrator composing submodules + backwards-compatible re-exports	465	PASS
Total		1,773

• Decomposition Invariant Test: Verified orch/orch.test.ts includes an explicit test asserting that all 6 modules are strictly below 500 lines (expect(lines).toBeLessThan(500)).
• Backwards Compatibility: Full compatibility is preserved via barrel re-exports in store.ts (export * from "./types.ts", lock.ts, frontier.ts, report.ts, tables.ts). Consumers importing from store.ts require zero code changes.

2. Evidence Receipts

• Tree hash for skills updated cleanly to a6e1c952923504d7a836b183f267b2812c50c73b3f83e5e90802317c45d9d1ff.
• Synchronized across all 5 receipts (antigravity-receipt.json, codex-receipt.json, grok-receipt.json, omp-receipt.json, opencode-receipt.json) and .audit/evidence/index.json.

3. Verification Test Execution Receipts

All 9 target verification gates executed and passed with exit code 0:

1. Bun Test Suite:
   • Command: cd skills/poteto-mode/scripts && bun test && cd ../../..
