garrytanandcapy-ai[bot] d6f4ea9f12 fix(pregate): test stage never hangs silently; small machines record the remote gate (Lane C, GBRA-95)
C1 diagnosis (gbrain 92f0ea87, a core edit selecting 3,683 local files, 358
serial; Bun 1.4.2 and 1.4.3 identical): --timeout was applied per runner
spawn (unit group plus one per serial file), so the check was unbounded, and
spawnSync buffered all output until it returned: 360 s with 0 bytes on stdout
and stderr. A backgrounded child holding stdout made spawnSync wait the full
timeout and then report exit 0 (a silent wait, then green). Not the Bun 1.4.2
spawnSync hang.

C2/C-b: test-tier commands (lanes runner, guards, the --remote gate) run via
lib/pregate/supervise.ts: own process group (setsid), stdout/stderr appended
to a log file (no pipes), async supervision; CheckDef.run may return a
promise and runPregate/withFingerprint await it (a rejection is incomplete).
Leftover group members are killed after exit; SIGINT/SIGTERM to pregate
SIGKILLs running groups, writes no pregate.json, exits 130/143. Windows:
taskkill /T /F (reparented or detached descendants can survive; documented).

C3/C-a: --timeout bounds the whole check; groups past the deadline are not
started. --stall-timeout <s> (default stall_timeout_s, else 300; 0 disables)
kills a group whose log stops growing and records PREGATE_STALLED naming the
last file started. Live stderr: PREGATE_TEST per file (bun test adapter; any
runner for one-file runs), PREGATE_HEARTBEAT after 60 s without progress,
PREGATE: tests <verdict>. --json stdout unchanged.

C4/C-c: under 8 cores, a base-branch remote_gate or a non-local test_backend
records the local tier as a requires-remote obligation with its command
(pregate.json/remote_gate or test_backend/<backend>). --remote runs the
declared remote_gate now (needs --allow-repo-commands, never --policy-from
head) under --spend-cap/GSTACK_SPEND_CAP_USD; it clears only on
PREGATE_REMOTE: tree=<tested tree> tests>0 failed=0 with exit 0, and reports
spent/reserved/unknown.

G1: new code PREGATE_STALLED has its result-codes row, troubleshooting anchor
and the installer-form error line (CODE; url#anchor).
