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.

After `/model`, the header kept the previous model's window ("15K /
1.0M" on a 262K model) until the next turn or a restart. The pager
caches the window inside its context snapshot (streaming `totalTokens`
updates refresh it from the catalog) and nothing refreshed the cache
when the session's model changed. Comparing cached numbers against
catalog windows cannot tell a catalog-derived total from a shell
effective limit (KIGI_DEBUG_CONTEXT_WINDOW, header upgrades), so the
shell, which installs the effective window, now reports it:
- kigi-shell: `handle_set_session_model` returns the installed window;
`model_switch::apply` stamps it as `totalContextTokens` in the
`session/set_model` response meta and carries it on the
`ModelChanged` broadcast (`context_window`, serde-default: old pagers
ignore it, old leaders omit it). The response meta previously
serialized the actor's inner `Result` and reported success on an
actor failure; that error now propagates.
- kigi-tui: `Effect::SwitchModel` reads the meta; `SwitchModelComplete`
carries `Ok(Option<u64>)`; the completion handler and the follower
`ModelChanged` arm call `AgentView::apply_context_window`, which
re-derives the snapshot (pct, free tokens) and reports whether it
changed so a follower redraws on a window-only change.
- Tests: the bare `/model <name>` dispatch path asserts the snapshot and
the drawn header; follower with/without the field; same-model new
window redraw; actor returns the window; serde round trip.

Ports grok-build's action stationarity breaker. A polling loop looks like
progress from inside the turn — every step succeeds — so nothing stops it
and it burns the whole budget re-reading one file. Nudge at 8 identical
batches, halt at 16, halt a pure no-op run at 4.
Three defects were found and fixed before this landed, none of which the
gates caught:
- The check runs AFTER execute_tool_calls, not before. Before it, the
assistant's tool_calls are recorded with no results, so pushing the
nudge triggers repair_dangling_tool_calls: synthetic "cancelled by the
user" results get spliced in, the real results land after a user
message, and dedup misses them — the orphan tool_result shape that
draws a provider 400. It is Ok-gated too, since one `?` inside can
leave a call resultless.
- `TurnOutcome::StationarityHalted` is its own variant grouped with
Completed, not a reuse of Cancelled. As a cancellation it would report
StopReason::Cancelled, fire the abort lifecycle, kill the turn's
subagents, grow the goal harness back-off streak until three halts
paused a running goal, and let completion-requirement recovery re-run
the very turn halted for looping.
- The no-op gate is size-based, not name-based. kigi registers the shell
tool as `run_terminal_cmd` and renames it `run_terminal_command`, so
matching on "bash" silently disabled the tighter ceiling while every
test still passed.
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).
One authority answers 'which credential may ride this request':
credential_class / manager_for / credential_for / bearer_resolver_for,
keyed by (platform, base_url). SessionCredential is an opaque type with
no production constructor, so a new call site cannot re-introduce the
session-bearer leak. Platform-scoped tests extended across all bearer
channels (session, aux, summary, subagent override).
Verified: cargo check --workspace --all-targets clean; kigi-shell and
kigi-tui suites green (6611+ tests).
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.
