ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This is an XXL, cross-layer production feature that adds a new usage RPC, transcript attribution and pricing logic, persistent caching, and new composer and usage-page behavior while also changing existing usage semantics. It additionally changes a capability default and adds a static-analysis suppression, so the scope and policy risk require human review. Not approved because:

Reviewed the runtime-history retention suggestion. Historical provider session IDs remain necessary to attribute older transcripts, especially for threads sharing a project root. The current code retains distinct previous cursors and does not truncate that identity history. I am keeping this behavior: imposing a cap here would silently lose attribution. A separate persisted identity index or explicit retention policy would be a separate change with its own migration and tests. The renderer suggestions concern the existing focused test harness. These regressions continue to use the repository’s current React test utilities; they are not presented as browser or native UI proof. A suite-wide renderer migration is outside this PR’s usage behavior. |

Thanks for the PR. We're not taking changes to the orchestration and provider layers right now: that part of the server is being rewritten for V2, and merging into the current code would either conflict with or be thrown away by that work. Closing for now. If this is still an issue once V2 lands, please reopen (or open a fresh PR against the new code) and we'll take a proper look. |

The Usage page explains aggregate spend, but nothing answers "what has this conversation cost?" while a thread is open.
What changed
The composer shows the active thread's estimated API cost. Opening it shows cache-write, cache-read and fresh input/output components.
UsageService.readThreadBreakdownattributes transcripts to a thread through its current and historical provider sessions (resume-cursor history is kept, so costs survive session switches and resumes) and its dedicated worktree. Targeted scans read identity metadata first and parse only matching transcripts. A compatible warm summary is reused unless the client sends a refresh token after a turn.serverGetUsageThreadBreakdownRPC. Clients call it only when the environment's usage contract version advertises it, so older servers render nothing instead of failing.useThreadCost+ThreadCostIndicatorin the composer footer. The query rolls over at local midnight and refreshes after completed turns.Stack
This branch is cumulative. It includes #9019 (Claude cost accounting) and #9015 (project breakdown), plus the usage range, zoom and cache-write pricing work they depend on. Merge those first; this PR's own increment is the thread breakdown and composer indicator. The branch is now one commit rebased onto current
main(20ef25037). Conflicts with #11021 were resolved by keeping its unpriced-model flag (unpricedRecords, "Unpriced" model rows, the excluded-records note) alongside this branch's cache-write columns and project scope.Verification
