BrowserProfileReporter sent profile updates to disconnected environments whenever cached server configuration or session state changed, producing repeated failed preview.reportProfiles calls.

Report only to connected, authorized environments with server-browser capability. Skip unchanged report tuples, re-report after reconnect/config changes, and retry eligible failures up to three times per environment and report tuple with increasing delays. Pending completions are invalidated on unmount so they cannot schedule stale reports.

Replaces #18148, which was closed for missing behavioral verification. This submission includes focused regression tests for disconnected environments, reconnects, retries, interruption, and unmount/Strict Mode lifecycle behavior. It also fixes both retry-budget and post-unmount findings from the previous review.

Scope and approval

Split from #17871 following Julius's one-problem review. This PR contains only browser-profile synchronization. Submitted as a focused correction to an existing background reporting path, without changing profile selection or adding a new workflow. The split request is not a claim of implementation approval.

Verification

• vp test run apps/web/src/browser/BrowserProfileReporter.test.tsx: 7 behavioral tests passed. Coverage includes exhausted retry budgets across multiple environments, fresh budgets for changed settings, late failure after unmount, successful deduplication/reconnect, cached configurations for disconnected environments, interrupted reports without automatic retries, and stale completions across React Strict Mode effect lifecycles.
• vp run --filter @t3tools/web typecheck: passed.
• Targeted lint and git diff --check: passed.
• Integrated client verification was not run in this session.

Split and verified with GPT-6.1-sol in the Codex harness, running in T3 Code. The original fix was authored with Claude Opus 5.5 in Claude Code.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This production change alters browser-profile synchronization by filtering environments, deduplicating reports, and adding retry and lifecycle state. Although narrowly scoped and well tested, the new asynchronous state machine materially increases runtime complexity, and the unresolved medium-severity retry finding remains an approval blocker.

📝 Walkthrough

Walkthrough

BrowserProfileReporter reports browser profiles to eligible connected environments. It tracks reports per environment, retries failed reports, and ignores stale completions. Tests cover retry behavior, deduplication, and lifecycle cases.

Changes

Browser profile reporting

Layer / File(s)	Summary
Per-environment reporting and validation apps/web/src/browser/BrowserProfileReporter.tsx, apps/web/src/browser/BrowserProfileReporter.test.tsx	The reporter filters connected environments by capability and scope. It tracks report state per environment, retries failures up to three times, and skips retries for interrupted commands. Tests cover retry limits, profile changes, connection changes, unmounting, and Strict Mode lifecycle behavior.

Merge Risk: ⚪ Minimal · up to ec0a6

Browser profile reporting has no identified merge-blocking issue in this review. It is ready to merge after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 2a963

Reporting is narrowed to connected, authorized environments. Shared retry timing can nevertheless consume retry budgets prematurely and leave profile information stale after temporary failures. The impact is bounded, and no authorization bypass was identified.

Retained concerns

• Low · reliability · inferred: Retry budgets are per environment and report tuple, but retry timing is shared. Failed entries have no next-eligible deadline, so dependency updates or another environment's timer can trigger retries early. Repeated early failures can exhaust a tuple's budget before recovery, leaving the server's profile catalog stale until the tuple changes or a reconnect is observed. The four-attempt cap limits request volume but does not preserve independent backoff.

Security review details

Security Blast Radius

• inferred — The changed caller narrows reporting recipients to connected environments that also satisfy existing server-browser capability and operate-scope checks. Each request continues to target one environment's existing in-memory profile catalog; the inspected change does not expand destination authority.

Trust Boundaries and Controls

• observed — Client eligibility checks are not the authoritative authorization boundary. The unchanged command runtime authorizes the selected destination before dispatch, and server RPC authorization requires preview operate scope before the profile-report handler runs.

Resilience and Maintainability Implications

• inferred — Per-entry pending flags, attempt caps, and completion-identity checks contain duplicate work and stale local scheduling. They do not make retry timing independent across environments, nor do they prove that an already dispatched request cannot update server state after local cleanup.

Hardening Proposals

• proposed — Track a next-eligible retry deadline for each environment and report tuple, and require every sweep to honor it. A shared timer can remain if it wakes for the earliest deadline while preserving independent budgets and stale-completion checks.

Note

Written by gpt-6.1-sol on behalf of Maria

Thanks for addressing disconnected profile reporting. The retry scheduler retains a failed report after preview permission or server-browser capability disappears, then repeatedly schedules its expired retry at zero delay. This needs correction and focused behavioral evidence under our verification requirement before reconsideration. Please invalidate ineligible retry entries and cover that transition; an issue can preserve the disconnected-reporting defect.
