Walkthrough

Adds a request-metrics subsystem and dashboard, integrates metrics into request flow, implements an auto-update checker, centralizes session utilities and session-manager changes (applyRequest now returns body+context), adds prompt-cache key utilities, recognizes gpt-5.2 model behavior, and updates tests/mocks.

Changes

Cohort / File(s)	Summary
Metrics Collection System `lib/metrics/request-metrics.ts`	New module implementing per-request aggregation (totals, prompt cache usage, tool usage/choices/calls, model distribution, reasoning effort/summary/verbosity) with capped `recentRequests` and public API: `recordRequestMetrics()`, `getRequestMetricsSnapshot()`, `resetRequestMetrics()`.
Metrics Integration `lib/request/codex-fetcher.ts`	Adds `ensureValidAuth` and `extractRequestMetrics` helpers; records metrics via `recordRequestMetrics()` after transformation and session application; uses session-applied body (effectiveBody) for headers, request body, and session response recording; short-circuits on auth errors.
Dashboard HTTP Server `lib/server/dashboard.ts`	New local HTTP server exposing `/metrics`, `/recent`, `/health`, and `/` (auto-refreshing HTML). Exports `startDashboardServer()` and `getDashboardPort()`, serves cache performance + request metrics snapshots and basic HTML UI.
Auto-Update Checker `lib/update/auto-update.ts`	New module that reads/writes update state in cache, throttles checks (15m), fetches npm registry metadata, compares versions, notifies via UI toast if newer, cleans old install artifacts, and persists state. Exports `runAutoUpdateCheck(client?)`.
Cache Configuration `lib/utils/cache-config.ts`	Adds `AUTO_UPDATE_STATE` to `CACHE_FILES` for persisting auto-update state.
Session Utilities & Manager `lib/session/session-utils.ts`, `lib/session/session-manager.ts`	Adds session utilities (hashing, equality, prefix analysis, key builders, `createSessionState`) and refactors `session-manager` to use them. Updates public API: `applyRequest` now returns `{ body, context }` (SessionApplyResult); `recordResponse` signature changed to accept sessionId and response.
Prompts Helpers `lib/prompts/codex.ts`	Extracts cache/tag-failure/fallback logic into `loadFromCacheOrBundled`, `handleLatestTagFailure`, and `checkFreshCache`, centralizing fallback paths.
Model / Request Transformer `lib/request/model-config.ts`, `lib/request/request-transformer.ts`	Adds recognition for `gpt-5.2` variants in model normalization and reasoning config; sets default text verbosity from model (gpt-5.2 => `low`).
Prompt Cache Key Utility `lib/utils/prompt-cache-key.ts`, `lib/request/prompt-cache.ts`	Adds `formatPromptCacheKey` utility and adopts it in prompt-cache logic; renames sanitizer helpers and adjusts empty-base behavior to use UUID-only prior to formatting.
Fetch Helpers / Session Application `lib/request/fetch-helpers.ts`	Applies `sessionManager.applyRequest` result (body+context) after transform; returns and uses the applied body for outgoing init and logs.
Types `lib/types.ts`	Adds camelCase alias `promptCacheKey?: string` to `RequestBody` (backwards compatibility).
Tests & Mocks `test/codex-fetcher.test.ts`, `test/request-metrics.test.ts`, `test/config.test.ts`, `test/request-transformer.test.ts`, `test/fetch-helpers.test.ts`, `test/session-manager.test.ts`, `test/index.test.ts`	Adds metrics tests and mocks, updates tests to the new `applyRequest` return shape (`{ body, context }`), and expands gpt-5.2 behavior coverage.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

Areas needing extra attention:
- lib/update/auto-update.ts — version comparison logic, TTL/throttle correctness, robust handling of network failures, and safe cleanup of filesystem artifacts.
- lib/server/dashboard.ts — server lifecycle, test-mode guards, and ensuring metrics endpoints return stable snapshots without blocking.
- lib/metrics/request-metrics.ts — aggregation correctness, deep-copy snapshot semantics, recentRequests cap behavior, and concurrency assumptions.
- session-utils ↔ session-manager integration — verify session key/hash/fork semantics, applyRequest contract and all callers updated to new shape.
- lib/request/codex-fetcher.ts & fetch-helpers — ensure effectiveBody usage (session-applied) and auth short-circuit behavior are correct and tested.

Possibly related issues

Auto-update: check npm latest, clear old install, toast user #67 — Implements the auto-update checker, notification and cleanup behavior; aligns with the new runAutoUpdateCheck implementation.

Possibly related PRs

Chore/codex max release review #31 — Changes to lib/request/codex-fetcher.ts and request/session flow; likely overlaps with the fetcher/auth/metrics adjustments here.
Add prefix mismatch diagnostics #73 — Also modifies session-manager internals and applyRequest behavior; strongly related to the session-utils/session-manager refactor.
Device/stealth #20 — Adjusts codex-fetcher and session applyRequest handling; related to how applied body/context are used.

Poem

✨ Counters hum, the recent list grows bright,
A tiny dashboard wakes on localhost night,
Updater peeks clouds for a newer sway,
Sessions fork, keys settle in their way,
Tests keep watch — metrics marching light.

All ESLint issues have been successfully resolved:

✅ Fixed cognitive complexity error in lib/request/codex-fetcher.ts:44 by extracting helper functions ensureValidAuth() and extractRequestMetrics()
✅ Reduced complexity in lib/prompts/codex.ts:206 by extracting helper functions loadFromCacheOrBundled(), handleLatestTagFailure(), and checkFreshCache()
✅ Fixed no-param-reassign warnings in lib/server/dashboard.ts by using new variables instead of modifying function parameters
✅ Removed unused escapeHtml function warning (function didn't exist, was outdated warning)
✅ Reduced file length in lib/session/session-manager.ts from 604 to 380 lines by extracting utilities to session-utils.ts

The codebase now passes all ESLint checks with no errors or warnings.

🔇 Additional comments (9)

lib/utils/cache-config.ts (1)

40-41: LGTM!

The new AUTO_UPDATE_STATE entry follows the established naming convention and integrates cleanly with the existing cache file structure.

lib/update/auto-update.ts (1)

143-194: LGTM on the update check flow.

The throttling, version comparison, notification deduplication (24hr cooldown), and cleanup sequence are well-structured. State persistence at each step ensures recovery from partial failures.

lib/server/dashboard.ts (3)

20-37: Unused function needed for security.

The static analysis correctly identifies escapeHtml as unused. However, this function is essential for preventing XSS in the dashboard HTML generation (see comment on line 85).

8-18: Static analysis false positive on parameter mutations.

The linter warnings about assigning to res.statusCode and calling res.setHeader() are false positives. Mutating ServerResponse is the standard Node.js HTTP API pattern. These can be safely ignored or suppressed with // eslint-disable-next-line if preferred.

144-168: LGTM: Robust server initialization.

The server implementation correctly:

Binds to localhost only (security)

Uses dynamic port allocation (flexibility)

Prevents multiple starts (idempotency)

Skips in test environment (test isolation)

Logs startup and handles errors gracefully

lib/metrics/request-metrics.ts (4)

1-50: LGTM: Well-structured type definitions.

The three types provide a clean separation of concerns: input for recording, summary for individual requests, and snapshot for aggregated metrics. Optional fields are appropriately marked.

69-131: LGTM: Correct metric recording logic.

The recording logic correctly:

Increments all relevant counters

Uses nullish coalescing for safe record updates

Caps recent requests at 50 entries

Creates complete request summaries with timestamps

133-155: LGTM: Safe snapshot generation.

The snapshot uses spread operators to create shallow copies of records and the recent requests array, which is sufficient since the data structures contain primitives and immutable summaries.

157-186: LGTM: Clean public API with singleton pattern.

The reset functionality comprehensively clears all tracked state, and the public API provides a clean interface to the singleton collector. This pattern is appropriate for application-wide metrics.

lib/server/dashboard.ts (1)

68-68: Critical: XSS vulnerability in innerHTML concatenation.

Line 68 directly concatenates user-controlled values (ts, model, url, cache, tools, reasoning) into innerHTML without escaping. If a request URL or model name contains malicious HTML/JavaScript, it will execute in the dashboard context.

Implement HTML escaping for all interpolated values:

+    function escapeHtml(text) {
+      const div = document.createElement('div');
+      div.textContent = text;
+      return div.innerHTML;
+    }
     for (const item of (recent.recentRequests || [])) {
       const tr = document.createElement('tr');
       const ts = new Date(item.timestamp).toLocaleTimeString();
       const model = item.model || '';
       const url = item.url ? item.url : '';
       const cache = item.promptCacheKey ? 'yes' : 'no';
       const tools = item.toolCount + (item.toolChoice ? ' (' + item.toolChoice + ')' : '');
       const reasoning = (item.reasoningEffort || item.reasoningSummary || item.textVerbosity) ? 'yes' : 'no';
-      tr.innerHTML = '<td>' + ts + '</td>' + '<td>' + model + '</td>' + '<td><code>' + url + '</code></td>' + '<td>' + cache + '</td>' + '<td>' + tools + '</td>' + '<td>' + reasoning + '</td>';
+      tr.innerHTML = '<td>' + escapeHtml(ts) + '</td>' + '<td>' + escapeHtml(model) + '</td>' + '<td><code>' + escapeHtml(url) + '</code></td>' + '<td>' + escapeHtml(cache) + '</td>' + '<td>' + escapeHtml(tools) + '</td>' + '<td>' + escapeHtml(reasoning) + '</td>';
       tbody.appendChild(tr);
     }

Alternatively, use safer DOM manipulation:

     for (const item of (recent.recentRequests || [])) {
       const tr = document.createElement('tr');
-      const ts = new Date(item.timestamp).toLocaleTimeString();
-      const model = item.model || '';
-      const url = item.url ? item.url : '';
-      const cache = item.promptCacheKey ? 'yes' : 'no';
-      const tools = item.toolCount + (item.toolChoice ? ' (' + item.toolChoice + ')' : '');
-      const reasoning = (item.reasoningEffort || item.reasoningSummary || item.textVerbosity) ? 'yes' : 'no';
-      tr.innerHTML = '<td>' + ts + '</td>' + '<td>' + model + '</td>' + '<td><code>' + url + '</code></td>' + '<td>' + cache + '</td>' + '<td>' + tools + '</td>' + '<td>' + reasoning + '</td>';
+      ['timestamp', 'model', 'url', 'cache', 'tools', 'reasoning'].forEach(field => {
+        const td = document.createElement('td');
+        let value;
+        if (field === 'timestamp') value = new Date(item.timestamp).toLocaleTimeString();
+        else if (field === 'model') value = item.model || '';
+        else if (field === 'url') {
+          const code = document.createElement('code');
+          code.textContent = item.url || '';
+          td.appendChild(code);
+          tr.appendChild(td);
+          return;
+        }
+        else if (field === 'cache') value = item.promptCacheKey ? 'yes' : 'no';
+        else if (field === 'tools') value = item.toolCount + (item.toolChoice ? ' (' + item.toolChoice + ')' : '');
+        else if (field === 'reasoning') value = (item.reasoningEffort || item.reasoningSummary || item.textVerbosity) ? 'yes' : 'no';
+        td.textContent = value;
+        tr.appendChild(td);
+      });
-      tbody.appendChild(tr);
