Summary

  • resolve BIGMODEL_API_KEY, Zhipu/GLM aliases, and known GLM relay files only for the China-mainland BigModel route
  • keep the standard Z_AI_API_KEY available to the explicitly selected global or China region
  • reject canonical api.z.ai / open.bigmodel.cn endpoint overrides when they conflict with the selected region, before bearer auth is attached
  • add a first-class z.ai/GLM API-key field and region-aware console link in provider settings
  • remove browser discovery from context-free Kimi token resolution so the settings-aware web strategy is the sole browser-import owner and Cookie Source Off is honored on every path

This is the in-house Slice C takeover of #2351. The contributor branch mixed GLM discovery with Kimi monthly enrichment and other provider changes in conflicted commits, so this focused region-routing slice is reimplemented with contributor credit preserved.

Root cause

The existing z.ai resolver had one generic environment key and region selection, while the proposed BigModel aliases and local relay files are specifically China-issued credentials. Without a region-aware resolver, those credentials could become candidates for the global host. Canonical endpoint overrides were also syntactically validated but not checked against the selected region before authorization headers were built. Separately, Kimi's context-free token helper could import browser cookies without access to the provider's Cookie Source setting.

Verification

  • focused z.ai/Kimi policy suites: 28 tests passed
  • BigModel aliases and relay files are unavailable to Global
  • both canonical cross-region override directions fail before the transport records a request
  • Cookie Source Off policy covers all Kimi browser-import ownership paths
  • source-blind CLI checks confirm Global rejects a BigModel-only key, China rejects an api.z.ai override, and Kimi Off exposes no web strategy
  • make check — passed, 0 format or lint violations
  • make test — 802 selections in 67 groups passed; 0 failed groups, retries, or timeouts
  • isolated autoreview — clean, no accepted/actionable findings

Live CN account verification was not run in this lane. After release, verification is requested from the reporter community on #2351, #2349, and #2500 for both BigModel and global z.ai account routes.

P2 Badge Don't fail quota refresh on optional model endpoint mismatch

When both overrides are set, Z_AI_QUOTA_URL wins for the required quota request and Z_AI_API_HOST only feeds the optional model-usage calls; this upfront validateEndpointOverrides now rejects a stale canonical API host (for example Z_AI_QUOTA_URL pointing at BigModel CN while Z_AI_API_HOST=api.z.ai and the selected region is CN) before fetchUsage can run. That turns an optional chart-endpoint mismatch, which the later fetchModelUsage blocks already catch as non-fatal, into a full usage refresh failure; validate only the quota endpoint here or defer API-host region checks to the optional model-usage path.

What this changes

This PR adds region-aware z.ai/GLM credential discovery and endpoint validation, a z.ai API-key settings field, and consistent Kimi Cookie Source enforcement.

Merge readiness

⚠️ Ready for maintainer review - 4 items remain

How this fits together

CodexBar resolves provider credentials from settings and environment values, then runs a fetch plan to retrieve usage for the menu-bar UI. The changed z.ai path must bind the selected region to both credential selection and endpoint validation before authenticated requests are sent.

Before merge

  • Wire the selected-region resolver into the active plan (P1) - The new ZaiAPIFetchStrategy is never returned by fetchPlan; both active Swift and JavaScript paths still call the legacy inferred-region resolver. With China selected and only BIGMODEL_API_KEY or a relay-file key, the active refresh therefore remains unavailable unless an endpoint override happens to imply China.
  • Defer optional API-host validation (P1) - fetchUsageWithModelUsage validates both overrides before the required quota request. When Z_AI_QUOTA_URL is valid but a stale canonical Z_AI_API_HOST mismatches the selected region, refresh now fails instead of returning quota data and treating model usage as optional.
  • Resolve merge risk (P1) - China users with only a BigModel alias or relay-file key still receive missing credentials because the active plan uses inferred rather than selected-region resolution.
  • Resolve merge risk (P1) - A stale canonical model-host override can make required quota data unavailable even when the selected-region quota endpoint is valid.

Technical review

Best possible solution:

Use the selected-region resolver in every active z.ai strategy, and validate only the required quota endpoint before quota retrieval while leaving model-host validation inside the optional model-usage fetch.

Do we have a high-confidence way to reproduce the issue?

Yes, from source: select China with only BIGMODEL_API_KEY or a relay-file key and run the active plan, which still resolves through the legacy inferred-region path. A separate source path shows a valid quota override plus stale mismatched model host aborting the combined refresh before quota retrieval.

Is this the best way to solve the issue?

No. The intended region-aware design is appropriate, but the branch must connect it to the active Swift and JavaScript strategies and preserve required quota refresh when optional model usage is unavailable.

* Port upstream 0.48.0: bound serve request heads

* Test serve deadline-driven connection recovery

* Port upstream 0.48.0: serve dashboard + snapshot contract

* Port upstream 0.48.0: codexbar dashboard command

* fix(dashboard): coordinator lost-wakeup/cancellation, daily totalCost wire, bare --output, camelCase schema

F1: coordinator.rs registers the Building waiter's Notified while the lock
is held (await_build helper), closing the notify_waiters lost-wakeup window;
a BuildGuard resets a stranded Slot::Building to Empty + wakes waiters when a
build is cancelled or panics. Adds deterministic lost-wakeup + cancel/panic
regression tests with tokio::time::timeout bounds. Single-flight, TTL,
late-result delivery, and errors-not-cached semantics preserved.

F2: data.rs emits the upstream daily wire key 'totalCost' (was cost_usd);
dashboard.html gates on 'daily.some(v => (v.totalCost || 0) > 0)' and every
per-row read uses 'd.totalCost'. Adds wire/HTML agreement and positive/zero/
empty chart behavior tests.

F3: dashboard.rs write_atomic treats an empty Path::parent as '.' so
'--output bare-name.json' writes to the working directory. Test covers bare
relative create, replacement, and no temporary leftover.

F4: AccountPayload and StatusPayload serialize camelCase (updatedAt) to
match pinned v1; golden assertions verify 'updatedAt' exists and 'updated_at'
does not.

* Port upstream 0.48.0: OpenCode Go per-model daily cost breakdown

Extract each local assistant message's modelID from opencode.db (the real
model behind the constant opencode-go Zen-proxy providerID) and group cost /
request counts by (day, model) instead of just by day, so the shared Cost
history chart shows a per-model breakdown for OpenCode Go the same way it
already does for Codex/Claude. Rows with no modelID fall back to an 'unknown'
bucket; whitespace-only ids collapse to 'unknown', whitespace-padded ids merge
with the trimmed bucket (upstream steipete#2649).

Provider-local: the SQL extraction, model normalization and (day, model)
aggregation live in the OpenCode Go local reader. The shared cost surfaces are
reused, not duplicated -- get_daily_cost_history gains an 'opencodego' arm and
CostScanner gains scan_opencodego_with_cancel that maps the provider-local
summary onto the existing CostSummary (total_cost_usd, by_model, sessions_count,
period), so the chart's local-usage panel and daily cost history treat OpenCode
Go like Codex/Claude without a bespoke chart surface.

No Codex/Claude pricing policy is copied; no duplicate chart machinery.

Tests: 11 focused regressions covering multiple models/days, same-model merge,
step-finish model inheritance, unknown/whitespace-only/whitespace-padded model
ids, zero-cost rows, malformed rows, history-window exclusion, local-day
boundary keying, deterministic (day, model) ordering, summary aggregation, and
Zen-wait independence of the pure aggregation.

* Port upstream 0.48.0: parse CommandCode rolling windows + GOAT plan

F12 (steipete#2630): parse windowLimits.fiveHour/weekly (root or nested in
credits) into primary/secondary rate windows with number-or-string
coercion and epoch-s/epoch-ms/ISO-8601 resetAt handling; monthly grant
moves to tertiary and uses the plan catalog for its total.

F13 (steipete#2706): add the individual-goat plan (0/mo) to the plan catalog,
recognize the new commandcode_prod_.session_token cookie names ahead of
the legacy better-auth family (bare tokens keep the legacy name), and
narrow pasted headers to the session cookie per upstream
CommandCodeCookieHeader.override.

Regressions: both upstream window-limits fixtures copied verbatim;
cookie priority/case-folding/family tests; plan catalog + login-method
and monthly-window mapping tests.

* Port upstream 0.48.0: derive OpenRouter key meter from server remaining

F14 (steipete#2612): the key-limit meter and its left/used text now come from the
server-reported current-period limit_remaining (clamped to [0, limit]:
negative reads exhausted, above-limit reads 0%) instead of lifetime usage.
Without a server remaining, fall back to the period usage matching the
declared limit_reset window, then cumulative usage; keys without any
usable quota source keep the meter hidden. Adds wire decoding for
limit_remaining/limit_reset.

* Port upstream 0.48.0: preserve ZoomMate browser cookie scope

F16 (steipete#2627): browser-imported cookies keep their raw host scope instead of
being merged into one header reused on host failover. Chromium/Firefox
host keys carry the scope (leading '.' = parent-domain), so each
destination host (ai.zoom.us / zoommate.zoom.us) now gets its own header
via RFC 6265 domain matching: parent-domain sessions reach both API
hosts, host-only cookies never leak onto sibling hosts, non-API hosts
are never destinations.

Upstream fixture issue-2507-cookie-scope.json copied verbatim; regression
tests cover the per-host partition, suffix-attacker rejection, empty
domains, and the hostOnly/domain matrix.

* Port upstream 0.48.0: decode Copilot AI credits counter

A15 (steipete#2593/steipete#2613): quota snapshots now decode credits_used (number or
string) for token-billed seats. The absolute counter stays off the
rate-window path — it surfaces as an informational extra window
(ai-credits), matching the existing snapshot/bridge/diagnostics pipeline
without inventing a fake quota denominator.

Upstream carriesCreditsCounter parity: zero-entitlement placeholder
snapshots still yield their counter, so a business seat with no
renderable quota window no longer blanks out — its snapshot becomes an
informational credits row (preferred premium-, then chat-classified
entries) instead of the previous hard error. Seats without any counter
keep the existing token-billing error.

* Port upstream 0.48.0: classify Claude OAuth refresh failures, terminal backoff

F3 (steipete#2650): on Windows the credential file is readable, so the upstream
touch-completes-but-unreadable state has no equivalent — the matching
provably-unrecoverable-by-retry state is the refresh endpoint rejecting
the stored refresh token (400/401/403). Those now classify as terminal:
a 5-minute per-source backoff (upstream defaultCooldownInterval) instead
of a doomed grant on every poll, and an honest re-login message without
the useless retry tail. Transient failures (network, 429, 5xx) keep a
short 20-second cooldown (upstream shortCooldownInterval) so recovery
still lands quickly. Successful refresh clears state; a re-login via the
shared credentials file is adopted past any backoff as before.

Regressions: classification matrix, long/short backoff gating + purge,
distinct terminal/cooldown user messages.

* Port upstream 0.48.0: bounded Zen balance wait in OpenCode Go usage reads

F15 (steipete#2583): the Zen balance now joins usage reads with an explicit
policy bound measured from task creation — CLI usage/serve /usage reads
(requires_optional_usage_completeness, new FetchContext field) join for
the remainder of the 5 s optional-balance budget; background/UI/guard/
diagnose hooks keep the 250 ms grace, so a slow subscription fetch can
never stack a second full wait. Local (SQLite) reads gain the same
optional enrichment as web reads, matching the upstream local strategy.

The balance fetch itself is the upstream chain: dashboard page parse
first, dedicated billing server-fn (raw 1e-8 USD behind a customerID
marker, RSC-fragment tolerant) as fallback, 25 ms start delay, bounded
per-request, and abandoned-over-budget tasks are aborted instead of
leaking. A zero-cost balance embedded in the usage page still wins
without any extra request.

A14 (per-model cost breakdown by day) intentionally NOT in this commit.

* Port upstream 0.48.0: Claude OAuth refresh gate + serve/opencodego fixes (M1-M4)

M1: from_http_status terminal iff (400|401) AND OAuth error == invalid_grant
    (case-insensitive). 403 and 400/401-without-invalid_grant are transient.
M2: terminal gate indefinite until credential fingerprint changes or success
    clears; transient base 5min flat; eliminates repeated dead-grant retries.
M3: serve /usage sets requires_optional_usage_completeness false (background
    poll grace); CLI usage remains true.
M4: abort spawned Zen balance task on usage-page/parse error before early
    return.

* Port upstream 0.48.0: Kimi/GLM/z.ai China routing (WS5)

- Kimi Desktop monthly membership pool enrichment: read-only WAL-safe
  kimi-auth token reader for the Electron Chromium store (%APPDATA%/kimi-
  desktop), AES-256-GCM via existing browser cookie crypto; Code API + CLI
  snapshots merged with Monthly + Code 7-day membership windows (steipete#2622/A10).
- Cookie Source Off disables Kimi Desktop + browser import (manual cookie
  headers keep working) (steipete#2623/A12).
- Moonshot/Kimi Open Platform: MOONSHOT_REGION + region-bound
  CODEXBAR_MOONSHOT_API_KEY(_REGION) binding so CN/intl keys stay on their
  issuing hosts; provider renamed per upstream (steipete#2621/A11).
- GLM Coding Plan: 5-hour TOKENS_LIMIT window is primary, weekly secondary,
  MCP rendered as a separate named window; plan name falls back to
  plan/plan_type/packageName/level (steipete#2621/A11).
- z.ai region routing: BIGMODEL/ZHIPU(ZHIPUAI)/GLM env aliases and
  coding-relay key files only for BigModel CN; canonical cross-region
  endpoint overrides rejected before bearer auth (steipete#2623/A12).
- Shared WAL-safe read-only SQLite helper (core::sqlite) replacing the
  OpenCode Go-local copy, reused by the Kimi Desktop reader (steipete#2544 pattern).

* Port upstream 0.48.0: unify Pi-family (pi + OMP) agent sessions (WS6)

- One dialect-aware scanner: live pi/OMP process detection (basename +
  bun-shim handling, helper filtering), session-jsonl correlation per CWD,
  PID-only rows when no transcript can be attributed, upstream OMP profile /
  PI_CONFIG_DIR / --session-dir / settings.json root resolution with the
  same fail-closed validation, upstream fixtures copied verbatim (steipete#2626/A13).
- Wire shape: AgentSession gains optional dialect + sessionName; --json
  stays legacy Codex/Claude-only (v1) while --json-v2 emits the complete
  array; SSH session discovery negotiates --json-v2 with --json fallback.
- Local scanner adopts the shared bounded directory budget; provider
  labels Pi/OMP in the sessions UI (bridge DTO + locale keys).
- Remote plumbing (RemoteSessionFetcher) moved to agent_sessions/remote.rs
  and the Pi scanner split into pi_family/{mod,parser,roots} to keep every
  file under 1000 lines.

* fix(dashboard): enable waiter notification under the decision guard (F1)

Corrects the lost-wakeup fix in 87ff071: await_build re-acquired the slot
mutex AFTER the decision guard was released, so a build completing in that
gap could fire notify_waiters (and swap the slot) before the waiter ever
registered — the waiter then slept forever on an already-fired Notify.

Now the waiter constructs and enable()s an OwnedNotified (which owns the
Arc<Notify>, Send+Sync) while still holding the SAME decision mutex that
observed Slot::Building, carries the registered future out of the critical
section, and awaits it only after the guard drops. The builder can update the
slot and notify_waiters only while holding that same mutex, so registration
is provably ordered before any wakeup attempt for this build. await_build
helper removed.

Regression: completion_in_decision_window_sets_waiter_notified drives the
waiter with manual polls and forces build completion + notify_waiters into
the exact decision->await window (slot manipulated directly; zero scheduler
dependence). Existing racing/cancel/panic regressions and single-flight, TTL,
late-result, and errors-not-cached behavior unchanged.

Also repairs two FetchContext initializers in source.rs for the integrated
requires_optional_usage_completeness field (E0063 at d2a63eb; false =
FetchContext::default, no behavior change).

Verified: cargo fmt --all --check clean; cargo clippy -p codexbar
--all-targets -- -D warnings clean; 10/10 coordinator tests pass
(2 threads).

* Port upstream 0.48.0: Codex cost-scanner robustness (F1,F2,F18,F19)

WS2 — Codex cost cache and scan robustness, ported from upstream 0.48.0.

F1 (cache bounds): add CostUsageCacheBudget module with upstream's
256 MiB save / 320 MiB load / 25 000 entry caps. Load refuses to decode
artifacts above MAX_LOAD_BYTES (cheaper to rebuild bounded). Save prunes
out-of-window entries, then trims oldest in-window entries to fit the
budget, protecting partially-parsed (growing) files so append-only resume
keeps its catch-up progress.

F2 (fork catch-up resume): validate the cached resume offset is a real
line boundary (byte at offset-1 == newline) before resuming an append-only
parse. A partial trailing-line write leaves the offset mid-line; resuming
there corrupts the first record. When the check fails, fall back to a full
re-parse from zero instead of the append-only merge.

F18 (priced + unpriced Auto Review): codex-auto-review and the model-less
sentinel are now deliberately unpriced routing rows — tokens counted,
by_model row present with 0 cost, no fallback to gpt-4o rates. Add typed
ModelPricingCompleteness (Complete | Partial{unpriced_models}) to CostSummary
so the dashboard can label a partial breakdown.

F19 (overshoot contract + predecessor keys): document the save/load overshoot
contract — save may exceed MAX_FILE_BYTES up to MAX_LOAD_BYTES when protected
entries cannot be trimmed further. Predecessor-key acceptance is N/A locally
(local cache uses filename -v1 versioning, no producer-key field); documented
as a documented divergence.

* Port upstream 0.48.0: Codex windows/pricing (F5,F6,C4)

WS3 — Codex duration classification and pricing, ported from upstream 0.48.0.

F5 (duration classification 5h/weekly/30-day): centralize duration policy in
RateWindowCadence (Session/Weekly/Monthly/Unknown) with from_minutes() and
from_seconds(). Add MONTHLY_WINDOW_MINUTES (43 200) next to the existing
SESSION/WEEKLY constants. Update codex_window_role to use RateWindowCadence
so 30-day windows classify as Monthly instead of being swallowed into Weekly.

C4 (Fast cost semantics + Terra/Luna refresh): add codex_api_fast_multiplier()
(gpt-5.4/5.4-mini/5.6-sol/5.6-terra/5.6-luna → 2.0; gpt-5.5 → 2.5; else nil)
and codex_fast_cost_usd() (standard cost × multiplier with long-context guard
at 272 000 input). Wire into codex_costs::codex_cost_usd after canonical
resolution fails but before legacy gpt-4o fallback, for fast/priority model
IDs. Refresh Terra rates (2e-6/1.2e-5, long 4e-6/1.8e-5) and Luna rates
(2e-7/1.2e-6, long 4e-7/1.8e-6). Fast detection is name-based locally (upstream
uses a priority-trace SQLite DB scan — documented divergence).

* Port upstream 0.48.0: complete WS2+WS3 follow-up (A16,F6,F8,F5)

A16 (scan completeness JSON): add historyCoverageIsEstablished to CostSummary
and surface it in the CLI cost JSON as historyCoverageIsEstablished (Bool?,
null for non-Codex providers). Set from cache freshness + catch-up state so
callers know when a re-scan is pending. Provider-native-only flag is N/A
locally (no pi/OMP mirror sessions) — documented divergence.

F6 (manual reset backfill): add codex_reset_backfill in Tauri providers.rs —
backfills missing resets_at/reset_description on fresh Codex windows from the
cached snapshot when the cached reset is still future (fresh used_percent
untouched). Wired into refresh_provider before publishing so every surface
(tray, CLI, frontend) sees the backfilled reset. Implemented through the
existing provider refresh abstraction, not a generic trait hook.

F8 (cached spend during refresh): add refreshing + stale_updated_at to
UsageSpendRow (backward-compatible optional fields). When the Codex cache
was pruned for budget (previous_report set), the spend row shows the stale
timestamp and refreshing indicator so the UI can show old data while a
re-scan rebuilds the artifact. Frontend UsageSpendTab renders the indicator
and uses the UsageSpendRefreshing locale key.

F5 (monthly cadence wiring): add Monthly to WindowRole (managed accounts)
and wire monthly through the ambient provider (normalize_array_windows
4-tuple routes monthly to UsageSnapshot.tertiary). Add tertiary_label to
bridge ProviderUsageSnapshot (duration-cadence label via RateWindowCadence).
Frontend MenuCard.tsx uses tertiaryLabel with monthly localization (ProviderMonthly).
Tray provider_status_label for Codex picks first non-informational lane
(session → weekly → monthly). CLI usage.rs appends a monthly lane line with
RateWindowCadence-based label. Test added for Monthly role classification.

* Port upstream 0.48.0: fix fmt/clippy integration issues

- Remove untracked package-lock.json (pnpm repo, npm artifacts incompatible)
- cargo fmt --all: bridge.rs, providers.rs, usage_spend.rs, tray_bridge.rs
- clippy: move constant-size budget assertion into const block (assertions_on_constants)
- clippy: add TestCache type alias to simplify test helper return type (type_complexity)
- clippy: collapse nested if-let in tray_bridge.rs codex_lane_headline_window
  using let-chains (let-chains stable since 2025 edition)

* Port upstream 0.48.0: C4 centralize fast suffix stripping (audit fix)

Extract codex_fast_base_model() that strips -fast/-priority suffixes.
Both codex_api_fast_multiplier() and codex_fast_cost_usd() now use it
so the original suffix does not leak into the Standard base lookup.
Previously codex_fast_cost_usd passed the original model name to
codex_cost_usd, which failed for suffixed IDs like gpt-5.5-fast.

Tests added:
- test_codex_fast_cost_usd_suffixed_models_resolve_to_base:
  gpt-5.5-fast -> base gpt-5.5 × 2.5, gpt-5.6-sol-priority -> base
  gpt-5.6-sol × 2.0
- test_codex_fast_base_model_unsuffixed: unsuffixed and unknown
  models resolve to themselves.

* Port upstream 0.48.0: F8 clear previous_report after full scan (audit fix)

A completed full scan rebuilds the cache for the current window, so any
prior catch-up state is no longer pending. Clear previous_report before
save_cache so the persisted artifact no longer signals stale/refreshing.
Previously previous_report was set during save-time budget pruning but
never cleared, causing a permanent Refreshing indicator.

Test: previous_report_clears_after_successful_full_scan — first scan
clears, inject previous_report to simulate trim, full scan clears it.

* Port upstream 0.48.0: A16/F18 expose coverage+completeness in CLI JSON (audit fix)

A16 historyCoverageIsEstablished and F18 modelPricingCompleteness were
added to CostSummary in the prior follow-up but never wired into the CLI
cost JSON or text output. Now:
- JSON emits historyCoverageIsEstablished (bool for Codex, null otherwise)
  and modelPricingCompleteness ("complete" or {partial:{unpriced_models}}).
- Text output labels partial pricing and partial coverage when present.
- --provider-native-only flag added, maps to CostScanOptions::include_pi_sessions
  = false, excluding pi/OMP session mirrors. Documented divergence: no
  pi/OMP mirror sessions on this Windows build so the flag is accepted but
  has no observable effect locally.

Tests: json_output_emits_a16_and_f18_fields, json_output_a16_null_for_non_codex,
provider_native_only_flag_default_false.

* Port upstream 0.48.0: F19 refuse oversized cache + fix trim double-subtraction (audit fix)

F19: save_cache now checks the encoded JSON length against MAX_LOAD_BYTES
before persisting. If the artifact still exceeds the load budget after
pruning+trimming (e.g. a single protected entry alone exceeds the limit),
the save is refused — no persist/refuse/rebuild loop. Extracted as
CostUsageCacheBudget::should_refuse_persistence() pure helper for
testability.

Trim double-subtraction fix: trim_in_window_for_budget pre-subtracted
droppable[0] from the initial estimate, then subtracted it again inside
the loop — a double count. Now the initial estimate is the full
estimated_cache_bytes and the loop subtracts each candidate once.

Tests:
- should_refuse_persistence_at_and_above_limit (boundary 1024/1025)
- trim_estimate_no_double_subtraction_of_first_entry
- trim_drops_until_target_reached_then_stops
- save_cache_persists_small_codex_artifact (no false-positive)
- save_cache_refuses_non_bounded_provider_oversize (Claude gate)

* Port upstream 0.48.0: F2 boundary helper + scan-level negative regression (audit fix)

F2 (upstream 0.48.0 steipete#2648): add boundary helper tests for all edge cases
and a scan-level negative regression proving midline/truncated rewrite
forces full parse (no resume from stale offset).

Tests:
- is_line_boundary_offset_zero_returns_true (offset 0)
- is_line_boundary_offset_at_or_past_size_returns_true (EOF)
- is_line_boundary_offset_exact_newline_returns_true (valid boundary)
- is_line_boundary_offset_midline_returns_false (fall through)
- is_line_boundary_offset_missing_file_returns_false (probe fail)
- cost_scan_midline_rewrite_forces_full_parse_not_resume (scan-level)

* Port upstream 0.48.0: F5 cadence/routing/headline regression tests (audit fix)

F5 (upstream 0.48.0): boundary table for RateWindowCadence and routing
regression for normalize_array_windows + tray headline preference.

Tests:
- cadence_boundary_session_exactly_300 (Session)
- cadence_boundary_weekly_10080 (Weekly)
- cadence_boundary_below_monthly_43199_is_weekly (boundary)
- cadence_boundary_monthly_43200 (Monthly)
- cadence_from_seconds_rounding (0/neg→Unknown, 18001s→301→Unknown)
- cadence_label_keys (session/weekly/monthly/unknown)
- f5_normalize_array_routes_session_weekly_monthly_to_lanes
- f5_normalize_array_monthly_routes_to_tertiary_not_secondary
- f5_normalize_array_empty_returns_placeholder_primary
- f5_normalize_array_unknown_windows_fall_to_code_review
- f5_headline_prefers_non_informational_primary (Tauri)
- f5_headline_falls_back_to_secondary_when_primary_informational (Tauri)
- f5_headline_falls_back_to_tertiary_when_primary_and_secondary_informational (Tauri)
- f5_headline_returns_primary_when_all_informational (Tauri)

* Port upstream 0.48.0: F6 reset-backfill regression tests (audit fix)

F6 (upstream 0.48.0 UsageStore+CodexResetBackfill): regression tests for
codex_reset_backfill covering future/stale/no-cached/non-codex/existing
paths.

Tests:
- f6_backfills_future_cached_reset (future reset backfilled, used untouched)
- f6_does_not_backfill_stale_cached_reset (past reset skipped)
- f6_does_not_overwrite_existing_resets_at (fresh reset preserved)
- f6_skips_non_codex_provider (Claude skip)
- f6_skips_when_no_cached_snapshot (None cached)

Divergence: upstream weekly-confirmation exemption N/A locally — local
backfill is the observable analog (no weekly-confirmation guard exists).

* Port upstream 0.48.0: fix clippy lint in audit-followup test code (audit fix)

Fix 4 clippy -D warnings violations in the audit-followup test code:
- collapsible_if in cli/cost.rs partial pricing label
- field_assignment_outside_initializer in cli/cost.rs test
- field_assignment_outside_initializer in jsonl_scanner.rs test
- needless_borrows_for_generic_args in cost_scanner.rs test

* Port upstream 0.48.0: F19 refusal removes preexisting destination artifact (audit fix)

The prior F19 commit refused on oversized post-encode but left any existing
destination cache file in place; a stale/oversized artifact could persist
and trip the load-refusal path on the next scan, forcing an unnecessary
full rebuild from a poisoned artifact.

- save_cache now deletes the destination file on refusal (best-effort,
  mirroring the fs-delete idiom used elsewhere in core).
- Extracted save_cache_with_limit(provider, cache, cache_root, max_load_bytes)
  as a private testable helper; save_cache delegates with the production
  MAX_LOAD_BYTES const. Production limit behavior is unchanged.

Integration regressions (jsonl_scanner.rs):
- save_cache_refusal_removes_preexisting_destination_artifact: precreate
  real destination via save_cache_with_limit(usize::MAX), trigger refusal
  with limit=1, assert destination gone, no tmp artifact with content, and
  load yields empty cache (no rebuild loop).
- save_cache_at_exact_limit_is_accepted: encoded artifact at exactly the
  injected limit is persisted (boundary).
- save_cache_one_over_limit_is_refused_and_removes_destination: one byte
  over limit is refused and destination removed.

* fix: fan out dashboard build errors

* fix: pin Windows globalization timezone module

iana-time-zone resolves the Windows system zone through WinRT's
Windows.Globalization Calendar class, but nothing keeps that DLL loaded.
COM cleanup exercised by the notification sound/toast tests unloads it,
leaving windows-core's process-static factory cache pointing into an
abandoned mapping; the next get_timezone() call then access-violates
(observed under LLDB; full lib suite crashed 3/3 single-threaded).

Load Windows.Globalization.dll from System32 and pin it for the process
lifetime before any get_timezone() call, gated behind a one-shot
LazyLock so every caller waits for load+pin to settle. On pin failure
return UTC without calling iana-time-zone (an AV is uncatchable). Route
both project call sites (claude cli_reset, sub2api) through the new
crate-internal helper. No lockfile change.

* test: make globalization pin test host-independent

The self-hosted PR runner is a stripped Windows image without
registered WinRT types (ToastNotification not registered), where
pinning Windows.Globalization.dll can fail by design; the helper then
correctly falls back to UTC. Assert the environment-independent
contract instead: the pin attempt settles exactly once and every
caller observes the same decision.
