The persistence actor acked FlushAndAck unconditionally after writing its
pending merged notification: nothing was fsynced and every storage failure
was only warn-logged, so persist_ack, the reconnect flush and history
repair treated lost writes as persisted.
The barrier now writes the pending notification, reports the first storage
failure latched since the last barrier (every actor arm latches), and
fsyncs the whole session directory tree (files, directories, deletions).
Session directories are created durably (init and fork copy), and the
shared summary writer syncs its staged bytes before publishing and the
parent afterwards, so a concurrent /rename cannot publish unsynced bytes
over a synced summary.json. FlushComplete and the persist_ack, history
repair and end-of-turn callers propagate the io::Result; CopyFile fails on
a sync error but keeps the latch for the barrier.
Ported from upstream 1.0.1x (grok-build persistence.rs pending_write_error
+ durable storage helpers), reshaped without the dirty-file set.

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).
The PRD's first acceptance gate now holds: grep -RinE '\bx\.ai\b|grok'
crates/ --include='*.rs' → 0 matches (exempt: NOTICE and third-party
license archives, README provenance, and the required 'Based on Grok
Build Open Source' attribution, now sourced from version_attribution.txt).
Wire-visible renames (both sides in this repo, changed in lockstep):
- Auth method id 'grok.com' → 'kimi-code' (AuthMethodKind::KimiCode).
- Every x.ai/* and _x.ai/* ACP ext method and meta key → kigi/* /
_kigi/* (~200 names; grokShell → kigiShell). Session-file replay keeps
a read-side alias for the legacy '_x.ai/session/update' method so
existing updates.jsonl histories load; writes emit only the new name
(both directions test-pinned).
- Agent types grok-build* → kigi* with a documented legacy-prefix alias
at resolution time so persisted sessions keep resolving.
- ToolNamespace/BuiltinAgentName GrokBuild* → Kigi* (wire snake_case
kigi/kigi_concise/kigi_hashline; schema regenerated); grok_build
implementation dirs renamed to kigi*.
- x-grok-* headers → x-kigi-*, __GROK_* sentinels → __KIGI_*, themes
grokday/groknight → kigiday/kiginight (old persisted values fall back
to the default theme), web_fetch allowlist xAI hosts → kimi.com +
moonshot platforms, changelog CDN → this repo, grok-build changelog
archives deleted.
- BYOK default endpoint removed: [endpoints] api_base_url is now truly
optional with NO default — consumers fail fast with the flag name when
unset (no silent x.ai egress). Mock harnesses inject it explicitly.
- System-prompt identity fixed: 'released by xAI' → 'an unofficial
community CLI for Kimi' (template + regenerated encrypted form).
Also repaired pre-existing grok-era test debt found by the sweep: the
stale trace_classify default-model pin, the grok-pager UA label test,
pty-harness stale-binary reuse and non-hermetic moonshot routing (a PTY
test could previously reach the real api.moonshot.cn), and the outdated
oauth fixture scope key.
