Confine the browse preset and agent-driven autofill to the extension's own connection - #1991
Conversation
…s own connection A browse-preset assistant session was listed and continuable from the ordinary website (/my/assistant), and read_current_page was granted purely by preset, with no check on how the turn's request authenticated. internal/browsertools.Hub is keyed by user id, not session id, so a user with the extension connected elsewhere could get the "ordinary" website chat to silently read whatever page their extension had open. - GET /assistant/sessions no longer lists browse sessions (SQL layer), and the website treats a browse session reached by URL as unavailable, same as tailor. - read_current_page's registration and the turn's system prompt both resolve from one carrier-aware effectivePreset, computed once, so a browse turn that isn't authenticated as the extension degrades to an ordinary chat rather than getting the tool-less registry under the prompt that opens by insisting on the tool. - POST /me/autofill/run had the identical gap, and it writes into the live form on whatever page is attached rather than reading it — refused outright now unless the caller is the extension's own Bearer session JWT. - internal/auth gains ViaCookie and IsExtensionBearer, mirroring the existing ViaAPIKey, as the one shared definition of "this is the extension's own connection" every caller that needs it uses. Found and fixed across three rounds of code review after the initial fix shipped: an API-key bypass of the carrier gate, a prompt/tool-set mismatch that NormalizePreset's own doc comment warns against, an LLM-spend billing tag left on the wrong preset, the autofill gap itself, stale docs (AGENTS.md, the public API reference, a route comment), and duplicated carrier-check logic.

📝 WalkthroughWalkthroughThe change confines browse sessions and agent autofill to browser-extension authentication. It adds authentication-carrier detection, downgrades unauthorized browse turns to chat, removes browse sessions from website rails, updates frontend behavior, and revises API and OpenSpec contracts. ChangesExtension-bound assistant capabilities
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The change restricts browse access and autofill to the extension connection, but the new authorization check can currently treat unauthenticated requests as extension traffic. That could allow unauthorized page reading or live-form changes, so the PR is not safe to merge until the authenticated identity check is enforced. Sequence Diagram(s)sequenceDiagram

Require a resolved authenticated identity.
Line 79 returns true when no authentication middleware set either carrier flag. IsExtensionBearer then classifies an anonymous request as an extension Bearer request. A caller that uses this shared helper as its extension gate can admit unauthenticated requests.
Require UserID(c) before accepting the non-cookie, non-key carrier. Add an unauthenticated test case.

func IsExtensionBearer(c *fiber.Ctx) bool {
- return !ViaCookie(c) && !ViaAPIKey(c)

Update the design to use the shared carrier helper.
The final implementation centralizes !auth.ViaCookie(c) && !auth.ViaAPIKey(c) in auth.IsExtensionBearer(c), and both callers use that helper. These decisions and the migration steps still describe the old inline expression. Update them so the change record matches the implementation and does not encourage duplicate carrier logic.
The supplied internal/auth/middleware.go context and task 0.9 establish this shared helper.
Suggested documentation update

-returns `403` unless `auth.ViaCookie(c)` and `auth.ViaAPIKey(c)` are both false.
