* ci: ratchet synchronous child-process launches in main and shared code
The Electron main process freezes every window while a synchronous child
process runs, and on Windows each launch is slow because antivirus scans
it. Nothing stopped new synchronous launches from landing in main-process
code, and the spawn observer behind ORCA_MAIN_THREAD_DIAGNOSTICS only saw
async spawns, so the worst blocks were invisible to it.
Ratchet: check:main-sync-spawn-ratchet parses production src/main and
src/shared files (test-only paths excluded) and fails when a file not in
config/main-sync-spawn-baseline.txt reaches execFileSync, spawnSync or
execSync from child_process, runProcessSync from @orca/process-host, or
one of the synchronous secure-file writers (they run icacls on Windows).
Named, aliased, namespace, default, require() and import() forms count.
A baseline entry whose file no longer launches synchronously fails as
stale, so the list can only shrink. It runs in lint and in the PR
static-analysis job next to the process-host import check.
Observer: runProcessSync now reports to the spawn observer, timing the
whole call (that is how long the thread was stuck) and reporting from a
finally so failing, throwing and timed-out children are counted too.
Runtime behavior is unchanged except that the diagnostics observer now
sees synchronous launches; with no observer registered the sync path
pays one extra branch.
* ci: count sync launches per file and gate the repo's sync wrappers
The sync-spawn ratchet only tracked which files launched synchronously, so a
file already on the list (wsl.ts, win32-utils.ts, git-exec-file.ts) could add
more launches unnoticed, and new callers of the repo's own synchronous
wrappers passed CI.
The baseline now stores a per-file count of uses, in the same format as the
focus-read ratchet: a rise or a new file fails, a lower or zero count fails
until `pnpm check:main-sync-spawn-ratchet --prune` lowers it, and --prune
never raises an entry. Every value reference to a gated function counts
(call, hand-off, alias and its uses, re-export); imports alone count nothing.
Gated wrappers: gitExecFileSync (and the git/runner re-export),
restrictWindowsPathSync, hardenSecurePath when called with sync: true,
grantDirAcl, getWslHome, listWslDistros, wslUncDirectoryExists,
isWslAvailable (and the wsl.ts re-export), isPwshAvailable. Their 18
current caller files join the baseline.
Failure messages now give advice per family: the async process-host API for
child-process launches, the async twin for wrappers, and for the secure
writers a note that no async secure writer exists yet, so the sync one stays
and must never become a plain write (that drops the Windows ACL hardening).
Also refresh two stale blockMs descriptions and drop a no-op line from the
spawn-observer "stays silent" test.
* ci: count hardenSecurePath unless visibly async, and tighten ratchet tests
hardenSecurePath was counted only when `{ sync: true }` was written inline,
so moving the options into a variable or a spread dropped the count and the
check then asked for a prune. It now counts every use except a call with no
options or a spread-free object literal whose `sync` is absent or false.
Also: resolve backslash paths in the importing file as well as the
specifier; still visit heritage and instantiation expressions
(`extends mixin(fn)`, `fn<T>`); state the reference-only counting limit;
and point the secure-writer advice at raising this file's baseline count.
Tests cover the hardenSecurePath shapes, the alias chains that need the
fixpoint loop, and a prune that must not raise a grown row.
* test(ci): pin the main sync-spawn ratchet background step
* fix: count secure hardening calls with spread arguments
Reduce import-scanner work by omitting unused AST parents and the duplicate traversal. Run the mandatory process-host import check alongside static work and explicitly join it before CI can succeed.
Update both workflow phase/enforcement contracts and migrate the newer benchmark to the public subprocess package API. Keep the original package build path, manifests, runtime, test selection, and shard count. Independent native review is clean; validation and timing evidence are in the PR.
Extract subprocess execution and process contracts into @orca/process-host with explicit public entry points, independent checks, and one Node 18 compatible CommonJS runtime. Migrate application consumers and integrate package builds, dependency selection, import enforcement, and runtime resource staging.
Preserve daemon startup ownership and profile isolation, and qualify development rebuild recovery and concurrent output publication. Remove unnecessary aliases, test forwarding exports, and a duplicate output scan.
Validation: full typechecks, changed-code quality, package and artifact checks, native Windows builds/types plus 306 runtime tests, and independent native reviews.
Matched full E2E controls on original main and unchanged reviewed head both pass all 17 applicable tests (nine skips). Earlier intermittent E2E failures are documented in the PR; no assertions were weakened. The final combined-tree audit preserves both branches with no import-boundary violations.
