fix: mark personal-preference reads private and uncacheable - #1731
Conversation
The three GETs that answer a caller's own settings now declare `Cache-Control: private, no-store`: keyboard shortcuts, the enabled-model preference, and the caller's skill profiles. Each carries a request-level test through its module, and the conformance snapshot records the policy for exactly those rows. Claude-Session: https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1

📝 WalkthroughWalkthroughThe control plane disables caching for three user-specific GET routes. The web model-preferences route now uses the shared settings proxy. Tests verify response caching, request forwarding, status codes, and session-cookie handling. ChangesPrivate route response caching
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Preference reads now prevent browser caching, and model-preference updates use the shared proxy. Credential forwarding for those updates lacks an observable boundary assertion, so a proxy regression could cause authenticated updates to fail unnoticed. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

The control-plane declarations themselves are clean and no production file crosses the 1k-line threshold, but the model-preferences policy is lost at the browser boundary. The canonical proxy already solves that problem while deleting a bespoke handler, so this should be fixed before merge. The added route-local tests also duplicate existing contract/lifecycle coverage and, despite their size, miss the actual end-to-end gap.

[deep review] This policy does not reach the browser-facing /api/model-preferences response. packages/web/src/app/api/model-preferences/route.ts parses the control-plane response and constructs a fresh NextResponse without forwarding Cache-Control, so the primary web caller still has no explicit private/no-store policy. The neighboring keyboard-shortcuts and skill-profile routes already expose the code-judo move here: replace the bespoke 42-line web handler with settingsProxy(() => "/model-preferences", "model preferences"). That makes the cache behavior consistent and deletes duplicated auth, body parsing, response translation, and error handling. Please cover the web route boundary as part of that change; the new control-plane-only test passes while this regression remains.

Confirmed and fixed in a74563a: /api/model-preferences is now settingsProxy(() => "/model-preferences", "model preferences"), and route.test.ts at that boundary asserts the private, no-store header on the read and the forwarded update.

[deep review] These three new route suites add roughly 180 lines of repeated authentication/store/env scaffolding to assert a three-line policy change, but they do not add a distinct contract boundary: the catalog snapshot records each exact declaration, the admission-matrix integration test exercises each declared policy on production routes, and request-lifecycle.test.ts verifies that the policy is stamped onto responses. The incidental payload/store assertions cover unchanged behavior, and this testing shape still missed the model-preferences BFF dropping the header. Please keep the policy coverage in those canonical tests and spend the targeted request-level coverage at the web boundary where behavior can actually be lost. The PUT assertion below should also go: absence of Cache-Control is not a behavioral invariant and would make a future no-store hardening fail for no reason.

Agreed. The three route-local suites are removed in a74563a; the conformance snapshot and the lifecycle test carry the policy coverage, and the new test sits at the web boundary where the header was actually lost. The PUT no-header assertion went with them.
Review follow-ups. The bespoke web handler for `/api/model-preferences` rebuilt the response without the control plane's headers, so the policy declared upstream never reached the browser. The route now uses `settingsProxy`, like keyboard shortcuts and skill profiles, and a test at that boundary pins the private, no-store response for the read and the forwarded update. The three route-local control-plane suites are gone: the conformance snapshot records each declaration and the lifecycle test proves the header is stamped, so they duplicated coverage while missing the web boundary that actually dropped it.
