The full-workspace gates had never run on this platform: collapsible
ifs in the Windows shell probe, a same-type cast in the crash handler,
an unused AsRawHandle import, and the sandbox smoke-test example
building its unix-only body (libc, kernel enforcement) unconditionally.
The example now stubs main off-unix; formatting reflow from cargo fmt.

Port of upstream grok-build 0.2.113/0.2.114 fixes, extended to Kigi's
startup order.
- kigi-tty-utils runtime module: worker-cap policy (8 max) — tokio's
per-core default pins 100+ thread slots on many-core shared hosts
against RLIMIT_NPROC / pids.max, and later spawns die with EAGAIN.
- kigi-bin builds the main runtime with capped workers and reports an
out-of-threads host with a diagnostic + exit(1) instead of a panic.
- The pre-runtime optimization threads (HTTP warmup, early model
prefetch) spawn recoverably and degrade — their panic would have
preempted the runtime's own diagnostic.
- The per-session actor thread and its runtime report spawn/build
failure through the existing acp::Error / AgentBuildError boundaries
(new RuntimeBuild variant) instead of panicking the agent host.
- fsnotify's watcher thread spawn maps into FsNotifyError::WatcherStart
so callers degrade instead of crashing.

Port of upstream grok-build 1.0.1 (landed upstream 2026-08-06).
A child wedged in an uninterruptible kernel syscall (D-state) never
observes SIGKILL, and a background descendant can hold the output pipes
open past the kill; both previously stalled tool futures without bound.
- kigi-tty-utils: KILL_REAP_TIMEOUT (5s) + reap_killed_bounded — wait
for an already-killed child at most the bound, then abandon the corpse
to tokio's orphan reaper.
- local_terminal: pipe readers share their buffer with the spawner and
join under the reap bound on both exit arms (aborted readers are
awaited so no tail bytes race the take); the whole tree is enrolled in
a ProcessGroup and group-killed on timeout; the timeout arm returns
the synthetic result instead of waiting on the corpse. Grandchild
kill + prompt-return pinned by a ported unix regression test.
- kigi-tools: reap_killed_search_child wrapper; grep's four kill sites
reap bounded; glob's stderr goes to null (an unread pipe blocks rg on
warning backpressure) and its truncation kill reaps bounded.

Sweep every first-party crate source (1956 .rs files) to the project comment
guidelines: delete redundant restatements, decorative banners, change
narration, and end-of-line comments; keep and tighten the crucial ones
(invariants, bug rationale, SAFETY blocks, ported-source attribution).
No functional code changed. Every edit is proven comment-only against the
prior tree by a comment-stripping lexer (string/char/raw-string aware) plus a
separate doctest-fence check. Where removing a comment made rustfmt or clippy
want to re-lay-out adjacent code, the minimal triggering comment is restored so
code tokens stay byte-identical.
Gates green: cargo fmt --all --check (0 diffs), cargo check and cargo clippy
--workspace --all-targets (0 warnings).
Adds scripts/check_codegen_comment_guidelines.py — the enforcement gate for
these guidelines (flags banners, end-of-line comments, change narration, and
commented-out code).
