* 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
