Add pace to serve /usage rows by Finesssee · Pull Request #1067 · nesszer/Win-CodexBar

Finesssee · 2026-11-02T13:56:46Z

Summary

codexbar serve /usage rows now carry the same optional pace object as codexbar usage --json. Before, they had only provider, source, usage and cost, so a script polling serve couldn't read the reserve or deficit the tray panel shows.

The pace block that render_json_result builds is now the shared helper usage_pace_json in cli/usage/render.rs. usage --json output is unchanged.
serve builds each successful row with a new usage_row and passes Settings::weekly_progress_work_days, so weekly pace follows the work-days setting just like usage --json.
pace is left out when neither window has one. Error rows and timeout rows are unchanged.
docs/CLI.md documents the key next to /usage. There is also a CHANGELOG entry.

The issue's example also lists etaSeconds and summary. Those keys aren't in usage --json today, and the issue asks for the same object, so this PR keeps the usage --json shape (stage, deltaPercent, expectedUsedPercent, willLastToReset).

Commands run

All passed:

cargo fmt --all
cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
cargo clippy --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml --all-targets -- -D warnings
cargo test --manifest-path rust/Cargo.toml: 5567 passed, 2 ignored. That includes 2 new tests in cli/serve/data.rs: a weekly row carries the expected pace, and a row with no pace omits the key.

This is a CLI JSON change only, with no UI, so no CUA proof applies. The Tauri crate's code is unchanged, and its clippy run is clean.

Summary by CodeRabbit

New Features
- Successful rows in the /usage dashboard can now include optional pace data, matching codexbar usage --json.
- Pace reflects the configured weekly work-days setting and includes primary and secondary window data when available. It is omitted when neither window has pace information; error rows remain unchanged.
Documentation
- Updated the /usage dashboard documentation to describe the optional pace data and its window details.

Walkthrough

Successful codexbar serve /usage rows now include an optional pace object, using the shared helper from usage --json. The object follows the weekly work-days setting and is omitted when neither window has pace data. Error rows are unchanged.

Changes: Usage pace output

Layer / File(s)	Summary
Shared pace JSON helper `rust/src/cli/usage/render.rs`, `rust/src/cli/usage.rs`	The usage JSON renderer now uses `usage_pace_json` to produce primary and secondary pace values. The CLI module re-exports the helper for use by the serve module.
Pace data in serve usage rows `rust/src/cli/serve/data.rs`, `docs/CLI.md`, `CHANGELOG.md`	Successful `/usage` rows include `pace` when pace data is available. Tests cover pace values, the weekly work-days setting, and omission when neither lane has pace data. Documentation describes the optional field and weekly work-days behavior. Error rows remain unchanged.

Estimated code review effort: 2 (Simple) | ~15 minutes

Full details: Linked Issues check

Explanation

Issue #1057 requires optional pace on successful /usage rows, shared pace rules, weekly_progress_work_days, omission when no lane has pace, unchanged error rows, documentation, and tests. The reviewed fetch_usage_row passes the saved setting to usage_row. usage_row calls shared usage_pace_json and adds pace only when it returns data. Error handling remains separate. The supplied change summary reports tests for pace, work-day behavior, and omission, plus the required documentation. The shared helper keeps the existing usage --json shape, so the example-only etaSeconds and summary fields are not unmet requirements.

Full details: Out of Scope Changes check

Explanation

The changes support issue #1057. The shared helper removes duplicate pace serialization. The serve tests verify the new response contract. The CLI documentation and changelog describe the contract. No unrelated product or UI change is shown.

Full details: Provider Data Stays Siloed

Explanation

The pull request adds only provider-local pace data to each /usage row. The changed code passes the same provider_id used to fetch the row into usage_pace_json, and emits only primary, secondary, and pace metrics. It does not copy identity, plan, account label, or email data between providers or accounts. The new ProviderId::Codex references are test fixtures only, and no changed shared code adds matching on specific provider IDs.

Full details: Secrets Handled Safely

Explanation

The reviewed diff only adds a derived pace field to successful /usage JSON rows and factors the existing usage --json pace calculation into usage_pace_json. The changed modules add no tracing or print calls, error-string construction, file writes, credential deletion, or keyring access. ProviderFetchResult fields used by the row contain usage, cost, and a source label; credential-bearing transient fields are skipped from serialization. Tests use only the literal source label oauth and synthetic quota data.

Full details: No Unapproved Dependencies

Explanation

The authoritative PR diff changes only CHANGELOG.md, docs/CLI.md, and Rust source files. It does not modify any Cargo.toml, package.json, npm/yarn/pnpm lockfile, or pnpm workspace/package-manager pin. The no-unapproved-dependencies condition does not apply.

Full details: Ui Changes Include Windows Proof

Explanation

The pull request changes only CLI usage JSON, CLI documentation, and the changelog. The authoritative diff contains no files under apps/desktop-tauri/src or rust/src/tray, and it does not change the float bar, settings, or window chrome. The change has no visible UI effect, so Windows proof is not required.

Test the configured /usage path.

The new tests cover usage_row, but not the /usage path that reads Settings::weekly_progress_work_days. A regression that substitutes the default value in fetch_usage_row can pass both tests. Add a route-level or fetch-path test with a non-default configured work-day value and assert the resulting pace.

Review comment at @rust/src/cli/serve/data.rs around lines 645 - 683: Extend the usage tests beyond usage_row with a fetch-path or route-level test that configures a non-default Settings::weekly_progress_work_days value and asserts the resulting pace reflects that value. Verify the configured setting reaches fetch_usage_row rather than being replaced by the default. After applying the fix, consider running `coderabbit review --agent` for local review.

@coderabbitai Partly addressed in the next commit. usage_row_pace_follows_weekly_work_days builds a row with a non-default Some(5) work-days value and asserts its weekly pace runs ahead of the linear (None) pace. That proves the value passed to the row builder reaches the pace.

I skipped a route-level test. usage_response reads Settings::load() from the user's config file and runs a live provider fetch, and neither has a test seam in serve today. Adding one only for this would be a bigger change than the feature. The remaining wiring is a single pass-through, settings.weekly_progress_work_days, into fetch_usage_row, and the same code fills api_region from that settings value right next to it.

@Finesssee That scope decision is reasonable. The supplied code shows settings.weekly_progress_work_days passes through fetch_usage_row to usage_row without a default substitution.

usage_row_pace_follows_weekly_work_days adds coverage for the non-default value at the row-builder boundary. It does not test the settings-to-fetch path, so the original coverage gap remains. That gap is not evidence of a wiring defect.

I accept leaving the route-level test out of this PR. I am not requesting a test-seam refactor for this change.
