formatMultiplier rounded any value >= 0.01 with toFixed(2), so a
configured multiplier like 0.035 displayed as 0.04x in the /usage and
/admin/usage cost tooltips. Format with up to 4 decimals and trim
trailing zeros while keeping at least 2 decimals; display-only fix,
billing amounts were already computed from the true multiplier.
Persist reasoning ceilings and exact mappings for OpenAI groups, enforce them across HTTP and WebSocket forwarding, and invalidate cached auth snapshots.
Debounced requests can finish out of order, allowing an earlier response to replace newer results or repopulate a cleared field. Track a request generation and gate state updates, with deterministic regression coverage.
Constraint: Preserve the existing 300 ms debounce and admin usage API contract
Rejected: Add AbortController plumbing | sequence invalidation matches repository patterns without changing API signatures
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep async filter results gated against superseded queries
Tested: Focused Vitest (4 tests), vue-tsc, ESLint, and full frontend suite except two pre-existing rollback assertion failures
Not-tested: Live browser against production-sized user data

Resolve const-block conflict in openai_gateway_grok_cache.go:
keep #4590's client tool cache constants, drop grokFreeRolling24hTokenLimit
(moved to pkg/xai as IsGrokFreeRolling24hTokenLimit with legacy 2M support).
Subscription plans can carry a display-only ISO currency code, but the admin plan table and user plan cards still used a hard-coded dollar sign. Resolve the symbol through the shared currency helper while retaining existing number formatting, the currency code label, and legacy blank-currency behavior.
Constraint: Plans without a currency must keep the legacy USD display
Rejected: Reformat complete prices with Intl.NumberFormat | it would change existing decimals and remove the explicit currency code
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep plan currency symbols aligned across admin and user displays
Tested: targeted Vitest 4 tests; targeted ESLint; vue-tsc; Vite production build; full Vitest 1222 tests passed
Not-tested: Full Vitest has 2 unrelated upstream failures in admin.system.rollback.spec.ts

The in-place update ran entirely inside c.Request.Context(). Browsers and
reverse proxies commonly abort long-idle requests (axios global timeout
30s, nginx proxy_read_timeout 60s by default), which canceled the request
context mid-download and killed every slow update with
'download failed: context canceled' while the version stayed unchanged.
Users behind slow GitHub links saw the update button fail at a wall-clock
ceiling (~60s) on every attempt (#4504).
- Run PerformUpdate and RollbackToVersion on a context detached from the
request (context.WithoutCancel) and bounded by a 15-minute deadline so
the 10-minute GitHub download client owns its own timeout. A client
disconnect no longer aborts the binary swap; retries then hit the
system operation lock or report 'Already up to date'.
- Raise the frontend timeout for the update/rollback calls from the
global 30s axios default to 15 minutes so the browser can actually
wait for the result.
Fixes#4504
