Subject: [PATCH 2/9] [Bugfix #1024] Fix: bump CLI preflight timeout to 5s +
 configurable override

The 400ms cap on the `codev --version` startup probe was too tight against
legitimate latency sources (remote SSH, WSL, nvm/fnm/volta shim re-resolution,
AV scanning, network filesystems), producing a false `missing` status that
opened the 'Get started with Codev' walkthrough and no-op'd guarded commands
despite a healthy install.

- Default timeout bumped 400ms -> 5000ms (DEFAULT_VERSION_TIMEOUT_MS).
- New setting codev.cliVersionTimeoutMs (number, default 5000, min 100,
  max 60000) overrides it per-workspace, surviving extension upgrades.
- runCodevVersion now reports a timedOut flag; the OutputChannel logs a
  [Preflight] line naming the timeout value and recovery action when the cap
  fires, so a slow-env false-negative is diagnosable instead of silent.
- Relocated the vscode-free runCodevVersion probe + a pure resolveVersionTimeout
  helper into preflight-core.ts so they are unit-testable under vitest.
- Added unit tests covering the explicit-timeoutMs (positive) and
  setting-unset default (negative) cases.

+# bugfix-1024 — CLI preflight 400ms timeout false "CLI missing"
+
+## Investigate
+
+Issue #1024: `VERSION_TIMEOUT_MS = 400` in `packages/vscode/src/preflight/preflight.ts:42`
+is too tight. On slow envs (remote SSH, WSL, nvm shims, AV scanning) the `codev --version`
+probe exceeds 400ms → `decidePreflight` returns `missing` → walkthrough opens, Status row
+sticks at `missing`, guarded commands no-op. Root cause confirmed by reading the source: the
+budget value, not the resolver chain.
+
+### Fix shape (mechanical, per issue)
+1. Bump default 400 → 5000ms.
+2. New setting `codev.cliVersionTimeoutMs` (number, default 5000, min 100, max 60000) in
+   `package.json`, read by the preflight via `getConfiguration('codev')`.
+3. Log a `[Preflight]` line to the OutputChannel when the cap fires (timeout), naming the
+   value + recovery action.
+4. Unit test `runCodevVersion` honours explicit `timeoutMs`; default falls back when unset.
+
+### Key design decision
+`runCodevVersion` is **vscode-free** (only `spawn` + timer). Importing `preflight.ts` for a
+unit test would drag in `EventEmitter` (constructed at module load), `TowerClient`,
+`tower-starter` — fragile. So I relocate `runCodevVersion` + a pure `resolveVersionTimeout`
+helper + the timeout constants into `preflight-core.ts` (loads only `node:path`). The probe
+is unchanged (not rewritten — out-of-scope respected), just moved to the file the project
+already unit-tests under vitest. Added a `timedOut` flag to the return so the glue can log
+the timeout case distinctly from spawn-error / non-zero-exit.

+Implemented. `porch check` green (build 4.4s, tests 20.1s). Note: the porch
+`tests` check is `pnpm --filter @cluesmith/codev test` (the codev-package vitest),
+NOT the vscode-package vitest — so it doesn't touch my files, but it passes.
+The vscode-package vitest has 7 pre-existing FAILING files (unbuilt

+terminal-adapter/terminal-resolve/reconnect-link) — unrelated to this change.
+My new `preflight-version-timeout.test.ts` (12 tests) + the existing

 CMAP

codex + claude both noted comments still naming the old 400ms cap. Make them
version-agnostic: extension.ts now points at the codev.cliVersionTimeoutMs
budget; the #983 Tower-divergence comment drops the stale ~400ms figure.
Comment-only; no behavior change.

Subject: [PATCH 9/9] [Bugfix #1024] Simplify: drop clamp helper for idiomatic
 setting read

Per architect review at the pr gate: resolveVersionTimeout + MIN/MAX constants
were over-built for a constant bump. VSCode already returns the package.json
default for an unset setting and enforces minimum/maximum in its settings UI,
so the helper's unset-fallback branch was dead at runtime and only the marginal
clamp/non-number guard ran live.

- Read the setting with the codebase idiom:
  getConfiguration('codev').get<number>(KEY, DEFAULT_VERSION_TIMEOUT_MS),
  matching overviewRefreshSeconds et al.
- Delete resolveVersionTimeout, MIN_VERSION_TIMEOUT_MS, MAX_VERSION_TIMEOUT_MS;
  the 100/60000 bounds now live solely in package.json.
- Tests: drop the resolveVersionTimeout cases; runCodevVersion suite keeps the
  explicit-timeout (positive) + default-when-omitted (negative) + spawn-error +
  5000 regression-anchor coverage.

Trade-off: no runtime clamp of a hand-edited out-of-range settings.json value
(VSCode UI validation covers the realistic path).

+## Simplification (architect review at pr gate)
+
+Architect pushed back on the `resolveVersionTimeout` helper + MIN/MAX constants
+as over-built for a constant-bump bugfix. Walked through it: the helper's stated
+purpose (unset-fallback) is dead at runtime — VSCode returns the package.json
+`default` for an unset setting, so the undefined branch only ran in tests; its
+only live value was the clamp + a non-number guard, both marginal for a
+`"type": "number"` setting VSCode already validates in its UI.
+
+Collapsed to the codebase idiom (matches `overviewRefreshSeconds`):
+`getConfiguration('codev').get<number>(KEY, DEFAULT_VERSION_TIMEOUT_MS)`.
+Deleted `resolveVersionTimeout`, `MIN_VERSION_TIMEOUT_MS`, `MAX_VERSION_TIMEOUT_MS`.
+Bounds (100/60000) now live only in package.json (UI-enforced). `5000` lives in
+package.json + `DEFAULT_VERSION_TIMEOUT_MS` (param default + test anchor) — the
+irreducible minimum. Trade-off accepted: no runtime clamp of a hand-edited
+out-of-range `settings.json` value.
+
+Tests: dropped the resolveVersionTimeout cases; runCodevVersion suite now covers
+explicit-timeout (positive), default-when-omitted (negative), ok/spawn-error,
+and the 5000 regression anchor. check-types + lint + vitest green (41 tests).
