Summary

Mistral Vibe (ACP acpRegistry driver) turns recorded usageStatus: "unavailable", so the Usage pane and per-thread cost had nothing for sessions served by it — even though the same data reached thread-cost through provider-turn records.

• contracts: add "mistral-vibe" to UsageProviderKind
• acp-registry: capture per-turn PromptResponse.usage for the mistral-vibe agent (reportsPerTurnPromptUsage), matching what glm-acp-agent already does; the agent reports per-turn deltas after the accompanying agent-side fix
• acp-registry: add a transcripts usage reader for Mistral Vibe, which keeps no token history of its own — it reads JSONL exported from the provider-turn projection by a small sidecar (mistral-vibe-usage-export) into ~/.local/share/mistral-vibe-usage; the reader triggers a fresh export (best-effort, 10s timeout, gated on a configured instance) when directories() resolves
• web + mobile: provider lists, labels and colors for the new kind

Testing

• New usage.test.ts: clamping of cached-vs-uncached counters, malformed/empty line handling, strict counter typing (malformed lines drop), parseProjected ≡ parseLine
• 65 tests pass in the package; typecheck and lint clean
• Verified end-to-end on a patched install: GLM-5.3-flash rows (measured from the agent's own per-call usage) now appear in the pane

A turn with inputTokens=1000, cachedInputTokens=400, and cacheCreationTokens=100 is reported as 1100 input tokens, so cache-creation tokens are counted twice. uncachedInputTokens subtracts only cache reads, while cacheCreationTokens is added separately; clamp cache creation to the input remaining after cached reads and subtract it from uncached input.

Walkthrough

The ACP Registry driver now reads Mistral Vibe usage transcripts. Provider contracts, server aggregation, and mobile and web usage presentations include Mistral Vibe.

Changes: Mistral Vibe usage reporting

Layer / File(s)	Summary
Provider kind and presentation packages/contracts/src/usage.ts, apps/mobile/src/features/usage/usageProviders.ts, apps/web/src/components/usage/usageProviders.ts, apps/web/src/components/usage/UsageProviderChart.test.ts	The provider kind and mobile and web usage mappings include Mistral Vibe. The chart test expects a zero-valued Mistral Vibe band for the first day.
Parse and normalize usage records packages/provider-acp-registry/src/server/usage.ts, packages/provider-acp-registry/src/server/usage.test.ts	The transcript format validates usage entries and creates records with normalized token totals and a provider/session/turn deduplication key. Tests cover valid data, rejected entries, and equivalence between projected values and JSON lines.
Trigger export and resolve usage directory packages/provider-acp-registry/src/server/usage.ts	For configured Mistral Vibe instances, the reader starts the user systemd export service with a 10-second timeout, then resolves the configured usage directory or its default path. Export failures do not prevent directory resolution.
Register the ACP Registry usage reader packages/provider-acp-registry/src/server/driver.ts, apps/server/src/provider/builtInDrivers.ts, packages/provider-acp-registry/src/server/adapter.ts	The ACP Registry driver uses the Mistral Vibe usage reader, and the built-in usage driver list includes ACP Registry. The per-turn prompt usage flag applies to Mistral Vibe and glm-acp-agent.

The usage reader should use the repository’s Effect process boundary. No demonstrated user-facing failure blocks merging, but the dependency-boundary violation needs owner attention.

Explanation

The title names the main change: adding a Mistral Vibe usage provider for ACP sessions. It follows a conventional commit format. The title is long (84 characters) and includes a parenthetical clause, but the primary change is clear and matches the changeset, which adds the usage provider, the transcript reader, the per-turn usage capture, and the web and mobile provider entries.

Full details: Description check

Explanation

The description follows the template's main sections. It has a Summary section that states the problem and the change, and a Testing section with specific tests and results. It does not have the template's Problem, Change, and Scope and approval headings. The Scope and approval section is missing entirely. It does not link a triaged issue or a maintainer discussion, and it does not explain why the change qualifies without one. The Verification section does not include the before/after screenshots that a UI change needs. The web and mobile provider list changes are UI-related, but the description does not show a screenshot or recording of them. The author also does not state the model and harness used, although the description ends with 'Generated by Mistral Vibe.' The template asks for the model and harness, which that line only partly covers.

Resolution

Add a Problem section that states the expected behavior and reproduction steps or environment. Rename the Summary section to Change or align it with the template headings. Add a Scope and approval section that links the triaged issue or the maintainer discussion with the approval comment. If no prior issue exists, explain why the change qualifies for an exemption. Describe the verification in terms of the changed behavior. Add before and after screenshots of the Usage pane, or a short recording, and embed or link them. Name the model and harness that did the work, in the form the template asks for.

Move process execution to the repository's Effect process boundary.

The module imports node:child_process and disables the lint diagnostic. effect-services.md requires Effect services to use environment-provided dependencies. ChildProcessSpawner is already available in this package. A direct execFile also adds a ChildProcessSpawner requirement bypass that tests cannot replace. Use ChildProcessSpawner with a timeout, or document why a plugin cannot get it.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Make the export trigger non-blocking or deduplicate it.

directories() waits for systemctl --user start --wait for up to 10 seconds. Every usage scan pays this cost. Concurrent refreshes spawn parallel systemctl processes. Consider a shared in-flight guard or a short TTL so rapid refreshes reuse one export.

The static hint flags child_process. The arguments are constant, so there is no injection path here.

Verified in a real dev environment

partial verification only. this is not an end-to-end pass for mistral vibe usage.

• reproduced the missing mistral vibe usage filter on github/main (7171fdd7716b05dc1b4be40c26ac78e8bb35f80c) in a separate worktree, then checked out this exact head: daeb071ddedf1b3334bf558b854feb7fabcc6a96. ran vp i in both. only one background dev server ran at a time.
• used repository playwright and /usr/bin/google-chrome to add a real git repository as a project through the app. real codex gpt-6.1-sol turns completed on main and this head, returning usage-check-ok and pr-usage-check-ok.
• this head adds the mistral vibe filter. selecting it and refreshing shows zero sessions and no activity. switching to codex still loads its token and cost charts. the recording demonstrates those interactions, not successful mistral usage ingestion.
• blacksmith ran vp test run packages/provider-acp-registry/src/server/usage.test.ts apps/web/src/components/usage/UsageProviderChart.test.ts: 2 files, 5 tests passed. all 30 reported CI contexts were successful.

Not verified

• mistral vibe usage ingestion and per-turn totals. the app installed registry vibe 3.1.1. i configured an isolated VIBE_HOME to use the existing local openai-compatible responses proxy with gpt-6.1-sol, then submitted a real turn from the web composer. ACP initialization succeeded, but session/new never completed. i cancelled after 10m 12s. a separate direct ACP probe also stalled at session/new, so i cannot attribute that startup failure to this diff.
• the reader requires an out-of-tree mistral-vibe-usage-export.service. the service and export directory are absent here, and this pr supplies neither the service nor a producer for its expected JSONL records. even a completed provider turn does not give this reader a shipped path from the projection to its input files.
• the stock installed vibe source returns cumulative session counters in PromptResponse.usage (vibe/acp/agent.py, _usage, via session token totals). this diff treats them as per-turn counters. the separate agent-side patch mentioned in the description is not included, so correct accounting across successive turns remains unverified and incompatible with that stock implementation.
• native ios/android and desktop shells were not exercised on this linux VM. codex subscription limits returned JSON-RPC -32600 on both main and the pr through the local proxy; codex token and cost history did load.

short runtime transcript:

systemctl --user status mistral-vibe-usage-export.service --no-pager
Unit mistral-vibe-usage-export.service could not be found.
default export directory: absent
09:50:09.448Z ACP initialize started
09:50:11.318Z ACP initialize succeeded
09:50:11.319Z ACP session/new started
10m 12s: still waiting, cancelled through Stop generation

no code changes or pushes. a safe fix needs a shipped usage producer and a defined per-turn usage contract; i could not verify that fix while the real provider session could not start.
