## [2026-05-20T15:04:52Z] Task 1 baseline - Total tests: 7315 - Pass: 7312, Fail: 2, Skip: 1 - Build exit code: 0 (dist/ size: 13M, 1456 files) - Typecheck exit code: 0 - Packages: 15 package.json files under packages/, 3 private (ast-grep-mcp, rules-core, web) - Anomalies observed: 2 pre-existing test failures in `src/features/opencode-skill-loader/skill-content.test.ts` — ambiguous short name resolution returns 2 resolved skills instead of 1 when "debugging" + "playwright" are queried together. This is a REAL baseline failure; do not fix as part of this refactor plan unless explicitly directed. ## [2026-05-20T15:12:12Z] Task 2 pre-flight - `src/shared/deep-merge.ts`: pure, zero imports. - `src/shared/snake-case.ts`: imports `./deep-merge` only (moved together) — pure after extraction. - `src/shared/record-type-guard.ts`: pure, zero imports. - `src/shared/extract-semver.ts`: pure, zero imports. - `src/shared/frontmatter.ts`: imports `js-yaml` only. - `src/shared/file-utils.ts`: imports `fs` only. - `src/shared/contains-path.ts`: imports `fs` and `path` only. - `src/shared/port-utils.ts`: imports `node:net` only. - `src/shared/tool-name.ts`: pure, zero imports. - `src/shared/replace-tool-args.ts`: pure, zero imports. - `src/features/boulder-state/format-duration.ts`: pure, zero imports. - `src/shared/jsonc-parser.ts`: coupled to plugin basenames; decoupled via parameterized `detectPluginConfigFile(dir, options)`. - `src/shared/write-file-atomically.ts`: depends on omo-specific `./tolerant-fsync`; extraction deferred by scope decision (kept in-place). ## [2026-05-21T00:00:00Z] Task 7 (worktree) - Pre-flight import audit (`packages/ast-grep-mcp/src/*.ts`) shows only `mcp.ts`, `runner.ts`, and `cli-binary-path-resolution.ts` touch adapter/runtime-specific concerns. - Candidate extracted files are pure from MCP perspective: - `types.ts`: type-only, currently coupled only by `CliLanguage` source (`CLI_LANGUAGES`). - `language-support.ts`: CLI language enum + numeric defaults; no MCP/Bun coupling. - `pattern-hints.ts`: pure heuristics; no runtime coupling (intended identical behavior for pi/codex parity). - `result-formatter.ts`: pure string formatter over `SgResult`. - `sg-compact-json-output.ts`: pure JSON parsing/truncation logic; depends only on constants/types. - `runner.ts` split requirement confirmed: - Core should own `buildSgArgs()` + `runSg()` orchestration and error mapping. - OMO-specific binary resolution stays adapter-side (`getAstGrepPath` in `cli-binary-path-resolution.ts`). - OMO-specific process spawn stays adapter-side (`bun-spawn-shim.ts`), injected via core deps (`spawnProcess`). ## [2026-05-21T00:00:00Z] Task 8 (worktree) - Created `packages/comment-checker-core/` with `package.json`, `tsconfig.json`, `index.d.ts`, and `src/` barrel. - Moved pure apply-patch parser + metadata parsing into `packages/comment-checker-core/src/apply-patch-edits.ts`. - Moved shared comment-checker types into `packages/comment-checker-core/src/types.ts`. - Added injectable pure runner in `packages/comment-checker-core/src/runner.ts`: - `resolveCommentCheckerBinary()` - `runCommentChecker()` with injected `spawn`, `existsSync`, and timer functions. - Kept OMO-specific adapter pieces in place (`hook.ts`, `pending-calls.ts`, `initialization-gate.ts`, `downloader.ts`). - Added per-file shims at original locations: - `src/hooks/comment-checker/apply-patch-edits.ts` - `src/hooks/comment-checker/types.ts` - Updated `src/hooks/comment-checker/cli.ts` to keep Bun spawn glue locally while delegating pure runner + resolver to core package. - Updated `src/hooks/comment-checker/hook.ts` to import `extractApplyPatchEdits` from `@oh-my-opencode/comment-checker-core`. - Updated root workspace wiring (`package.json` workspaces, devDependency, typecheck:packages) and ran `bun install`. - Verification: - `bun run typecheck` exit 0 - `bun test` 7312/1/2/7315 (baseline-matching drift) - `bun run build` exit 0 ## [2026-05-21T00:00:00Z] Task 3 retry (worktree) - Extracted model resolution pipeline surface into `packages/model-core/` with moved sources/tests and package scaffold (`package.json`, `tsconfig.json`, barrel `src/index.ts`). - Added ProviderCache DI seam in model-core: - `model-resolution-pipeline.ts` accepts `providerCache`. - `model-error-classifier.ts` exposes cache-injected provider selector. - Kept OMO runtime cache implementation in `src/shared/connected-providers-cache.ts` and wired injections through shared shims. - Recreated per-file `src/shared` shims with explicit symbol re-exports (no `export *` in shims). - Moved `src/shared/model-capabilities/` subtree into model-core and kept shared adapter entry via `src/shared/model-capabilities/index.ts` wrapper. - Verification pass: `bun run typecheck`=0, `bun test`=7312/1/2/7315 baseline, `bun run build`=0. ## [2026-05-20T18:37:22Z] W2-QA gate - Verdict: REJECT. T6 `lsp-core` deferral accepted and not considered. - Evidence written under `.omo/evidence/w2-qa-*.txt` for all 10 requested checks. - Blocking failures: - Test delta drifted from baseline: `bun test` produced 7311 pass / 1 skip / 3 fail / 1 error / 7315 tests; extra failure is `src/shared/tmux/runner.test.ts:202` after timeout at `src/shared/tmux/runner.test.ts:199`. - `/tmp/w2-qa-equiv.ts` could not resolve `@oh-my-opencode/utils` from `/private/tmp/w2-qa-equiv.ts:1`. - Dependency DAG violation: `packages/agents-md-core/package.json:19` depends on `@oh-my-opencode/rules-engine`, a cross-Wave-2 internal dependency beyond utils. - `packages/rules-core/` still exists, although only `node_modules/` remains inside. - Passing blocking checks: package symlinks/LSP references, OpenCode coupling sweep, build exit 0, and `dist/` remained 13M. - Informational coverage concerns: `ast-grep-core`, `comment-checker-core`, `boulder-state`, and `agents-md-core` have zero co-located package tests; `boulder-state` has no critical-path test files. ## [2026-05-21] BOULDER COMPLETE All 40 plan checkboxes resolved (40 [x], 0 [ ], 1 [~] deferred for T6 lsp-core). **Final commits on dev (since baseline 6609d90b3):** - Wave 1: utils package extraction + W1-QA APPROVE - Wave 2: model-core, rules-engine, agents-md-core, ast-grep-core, comment-checker-core, boulder-state extractions + W2-QA APPROVE (T6 deferred) - Wave 3: meta-audits + opencode-coupling grep gate + AGENTS.md/ROADMAP docs + W3-QA APPROVE - Final Wave round 1: F2 + F3 APPROVE; F1 + F4 REJECT - Round 2 fixes: FIX-1 (model-core DI eliminated 4 back-imports), FIX-2 (14 evidence sentinels), FIX-3 (T4 doc edit split) - Final Wave round 2: F1 + F4 surface 2 new issues - Round 3 fixes: FIX-5 (audit allowlist for runtime.Bun.* dual-runtime pattern), FIX-6 (delete 855KB dead generated JSON) - Final state: all 4 reviewers APPROVE **Test baseline preserved exactly: 7314 pass / 1 skip / 2 fail / 7317 total** - 2 fails are pre-existing skill-content ambiguous short-name tests (untouched by refactor) - 1 documented flake: tmux runner test under heavy parallel I/O (passes 9/9 in isolation) **Architecture delivered:** - 7 Core packages in packages/ (utils, model-core, rules-engine, agents-md-core, ast-grep-core, comment-checker-core, boulder-state) - Per-file re-export shims at original src/ locations (never `export *`) - opencode-coupling-audit.test.ts enforces zero Bun.* or src/ coupling in package production code (test files exempt) - ProviderCache, ConnectedProvidersAdapter, SpawnFn DI interfaces for harness independence - API designed for future pi/codex adoption **Deferred future tracks:** - T6 lsp-core extraction (submodule strategy) - Pi adapter layer (senpi + extensions) - Codex adapter layer - rules-engine full Engine DI (originally planned in T4, scoped to rename only) - 3 orphan re-export shims for cleanup (apply-patch-edits.ts, model-capability-aliases.ts, model-capability-guardrails.ts) - Tmux runner test flake (documented) **Key learnings:** - Subagents running bash inherit the parent's cwd, NOT the worktree path — must use `workdir` parameter explicitly. FIX-6 subagent deleted from main repo by accident before catching this. - Coupling audit regex `\bBun\.` is too broad; negative lookbehind `(?
