Prepares the workflows for a GitHub merge queue on main, ahead of a ruleset that requires ci gate, Validate PR title and Validate PR title scope.
Root cause
A merge queue merges a group only after the required checks report on the merge group's commit. Those checks come from workflows that listen for merge_group. Today neither ci.yaml nor check-pr-title.yaml does, so every queued PR would wait until the queue's timeout and drop out. A few things also assume a pull request or a direct merge:
detect-code-changes takes its base from pull_request.base.sha || event.before. Neither exists on merge_group, so it would diff from the root commit.
The title checks read the PR title and changed files, and a merge group has neither.
tagpr opens the release PR with GITHUB_TOKEN, so its pull_request runs wait for an approval and never report. Its CI comes from a workflow_dispatch in release.yaml, but GitHub does not attach check runs from a dispatch to a PR. chore: release v20.0.49 #2018's head commit has the dispatched CI's check runs, yet its PR status rollup lists none of them, only the CI (release dispatch) commit status. Once ci gate and the title checks are required, every release PR would be blocked.
Renovate merges through the API (platformAutomerge: false), and GitHub rejects direct merges when a queue is required.
The create-pr skill merges with gh pr merge --squash --body-file to add Co-authored-by for issue reporters. The queue builds its own squash message, so that body would be dropped.
Design
ci.yaml
Listens for merge_group (checks_requested).
detect-code-changes diffs from github.event.merge_group.base_sha. For a group with several PRs, that diff covers every PR ahead in the group, which errs on the safe side.
Still running on merge_group: tirith scan and its SARIF upload, preflight, test, native builds, the pkg.pr.new publish and the e2e matrix. pkg.pr.new records any workflow_run, not only PR runs, and keys a non-PR publish by the checked-out SHA. So the queue publishes a preview of the merge group commit, and e2e installs the package built from the tree main will get. No PR comment is posted, because the run is not tied to a PR.
The SARIF upload keeps running on merge_group, because a commit that tirith blocks in the queue never reaches main, so no push run would publish its findings. Code scanning accepts uploads from merge queue refs; codeql-action's own workflows upload on merge_group.
Skipped on merge_group: the perf comments, which were already limited to pull_request. ci gate treats a skipped job as a pass.
Least privilege for queued code. A merge_group run gets the permissions the workflow declares, whereas GitHub caps a fork PR's pull_request token at read. The native build job no longer has actions: write, which nothing used: artifacts and the Actions cache authenticate with the runtime token, and cache-nix-action needs the API token only to purge caches. The job now has actions: read and contents: read on every event. Its Nix build gets the GitHub token only on push and workflow_dispatch, so pull requests and merge groups build without it. Every job a merge group runs now has a read-only token, apart from the SARIF upload's security-events: write, which runs only pinned actions.
Only main persists caches, and ci.yaml makes that decision itself. A workflow-level PERSIST_CACHES: ${{ github.ref == 'refs/heads/main' }} is passed to every Nix store and Cargo cache save. The Nix sticky disks are keyed by job, not ref. Pull requests and merge groups therefore mount main's warm disk with commit: false, so the clone is discarded. Before, only setup-nix-cache decided this, and on merge_group that local action comes from the queued commit. Limit: a queued commit that edits ci.yaml itself can still change this. Review before queueing is that boundary. The gate stops a changed local action, or code nobody reviewed, from writing a store main reads.
ci.yaml has no concurrency group, and nothing reads head_ref or a PR number outside the perf-comment job.
The build and publish checkouts no longer persist the job token into .git/config, where the code they run could read it.
check-pr-title.yaml
Listens for merge_group. Both jobs keep their names so the check contexts stay the same, and run their real steps only on pull_request. On merge_group, a no-op step reports success: the group is built only from PRs whose titles already passed. The scope job's label exemptions apply only on pull_request, so it is never skipped on merge_group.
Commit statuses are attached by SHA, so the dispatched runs report the exact required contexts that way, with the Actions token. That makes github-actions[bot], the app the ruleset names, the status creator.
CI's existing release status is renamed from CI (release dispatch) to ci gate.
release.yaml also dispatches check-pr-title.yaml. Its release-pr-statuses job posts Validate PR title and Validate PR title scope as success, without running repository code. The release PR's title comes from .github/tagpr-template.md. It posts only when the commit is the head of an open PR from that tagpr-from-* branch opened by github-actions[bot], and fails otherwise.
ci.yaml and check-pr-title.yaml also run on pushes to tagpr-from-*. tagpr's own pushes use GITHUB_TOKEN and start no workflow, but a person pushing to the release branch now gets the statuses re-posted for the new head. The trigger is not on release.yaml, whose tagpr concurrency group would let such a run replace a pending release run from main.
Renovate: platformAutomerge: true. Renovate turns on GitHub auto-merge, and GitHub queues the PR once its checks pass. The false came from the inlined shared preset, not a choice made for this repository. The repository already has "Allow auto-merge" turned on.
create-pr skill: merges with gh pr merge <pr> --squash and no --delete-branch or --body-file. That works with and without a queue: with one, gh warns that the queue sets the strategy and enqueues the PR. Reporter credit goes in as a Co-authored-by trailer on a commit in the PR, because the repository's squash message is built from the PR's commit messages (squash_merge_commit_message: COMMIT_MESSAGES).
Other workflows
update-pricing.yaml pushes straight to main through .github/actions/commit-and-push-main. It authenticates with GITHUB_TOKEN (gh auth setup-git) and commits as github-actions[bot]. A merge_queue rule plus required checks would reject that push, so the GitHub Actions app needs to be a bypass actor (below).
release.yaml (tagpr) pushes the tagpr-from-* branch and the release tag with GITHUB_TOKEN, but never pushes main. The release PR itself goes through the queue. Its required checks are reported as commit statuses from the dispatched runs (see above). On merge_group, the two release dispatch status jobs are skipped.
autofix.yaml pushes only to PR branches, through the autofix.ci app, so the main ruleset does not apply. A fix pushed after a PR is queued takes it out of the queue, as any new commit would. That is expected.
pr-gate, gate-close-pr, approve-contributor, issue-gate, check-links and pullfrog need no changes. None of them pushes to main or produces a required check.
Ruleset to enable after merge
Target ~DEFAULT_BRANCH. Keep deletion and non_fast_forward.
required_status_checks (all from GitHub Actions, integration_id: 15368), with strict_required_status_checks_policy: false because the queue already tests against the latest main:
ci gate
Validate PR title
Validate PR title scope
The old contexts (Detect code changes, lint-check, test, npm-publish-dry-run-and-upload-pkg-pr-now) should be dropped from the disabled main ruleset. lint-check no longer exists, and the others are covered by ci gate, which also passes on docs-only PRs.
check_response_timeout_minutes: 60. Recent CI runs on main take about 5 minutes, and the jobs' own timeouts top out at 30.
bypass_actors:
GitHub Actions, actor_type: Integration, actor_id: 15368, bypass_mode: always. Required for update-pricing.yaml's direct push to main. Note that this lets any workflow holding a contents: writeGITHUB_TOKEN push to main. A stricter alternative is a dedicated GitHub App token for commit-and-push-main, with only that app in the bypass list.
Optional: repository admins, actor_type: RepositoryRole, actor_id: 5, bypass_mode: pull_request. This gives an escape hatch to merge a PR past a stuck queue without allowing direct pushes.
Not needed in the bypass list: tagpr (it uses GITHUB_TOKEN, so it is covered by the Actions entry, and it never pushes main), autofix.ci (it only pushes PR branches), and Renovate (it merges through the queue).
Testing
actionlint: no new findings. The only errors are the existing - parallel: steps in ci.yaml and update-pricing.yaml, which are also on main.
A merge queue only merges a group once the ruleset's required checks
report on the group's commit, and those checks come from workflows that
listen for `merge_group`. CI listened only for push, pull_request and
workflow_dispatch, so a required `ci gate` would never report and every
queued PR would time out.
On merge_group there is no pull_request payload, so change detection fell
back to `github.event.before`, which is empty, and diffed from the root
commit. It now diffs from the merge group's base. The SARIF upload is
skipped there because the same commit is uploaded by its push run on main.
The perf comment already runs only on pull_request. The pkg.pr.new publish
and the e2e matrix keep running: pkg.pr.new records any workflow run and
keys the preview by the checked-out SHA, so the queue tests the package
main will get.
Both title jobs are about to become required checks, and a required check
must report on every commit the ruleset judges. The merge queue judges the
merge group commit, which has no PR title and is only built from PRs whose
titles already passed. tagpr's release PR is opened with GITHUB_TOKEN, so
its pull_request runs wait for an approval and never report; its CI already
comes from a workflow_dispatch in release.yaml for that reason.
Both jobs now pass without validating on merge_group and on a dispatch from
a tagpr-from-* branch, under the same job names so the check contexts
match. A dispatch from any other branch fails, so a dispatch cannot stand
in for a real title check. release.yaml dispatches the title workflow next
to CI.
With a merge queue on main, GitHub rejects direct merges through the API,
which is how Renovate merges when platformAutomerge is off. That setting
came in with the inlined shared preset rather than for this repository.
Platform auto-merge enables GitHub's auto-merge instead, which adds the PR
to the queue once its checks pass.
`gh pr merge --squash --body-file` merges directly. Under a merge queue the
queue builds the squash commit itself from the repository's settings (PR
title plus commit messages), so a custom body, and the Co-authored-by
trailer it carried for issue reporters, would be lost. The trailer now goes
on a commit in the PR instead.
No actionable comments were generated in the recent review.
Walkthrough
The changes update PR merge guidance and Renovate settings. GitHub Actions workflows now handle merge-group events in title validation and CI. Release-branch dispatch also runs title validation, and release-dispatch statuses use the ci gate context.
Changes: Merge queue workflow support
Layer / File(s)
Summary
Queue guidance and automation .agents/skills/create-pr/SKILL.md, .github/renovate.json
The PR guidance changes the squash merge command and requires reporter credit in a PR commit’s co-author trailer. It also notes that merging into a base branch with a merge queue queues the PR. Renovate platform automerging is enabled.
Title validation event handling .github/workflows/check-pr-title.yaml, .github/workflows/release.yaml
The title workflow handles merge-group events and manual dispatches. Title and scope checks run only for pull requests. Manual dispatch fails unless the ref begins with tagpr-from-; matching refs receive successful statuses for both title-check contexts. Release dispatch now runs the title workflow.
CI merge-group handling and statuses .github/actions/detect-code-changes/action.yaml, .github/workflows/ci.yaml
CI listens for merge-group checks, and change detection uses the merge-group base SHA as a fallback. Native-package build permissions are reduced, checkout credentials are disabled in specified jobs, and the Nix token is limited to push and workflow-dispatch events. Release-dispatch statuses now use the ci gate context.
ccusage/ccusage#2056: Adds reporter co-authorship instructions to the same create-pr skill. This PR changes the reporter-credit flow by requiring a co-author trailer on a commit before merging.

ℹ️ Minor wording nits only — the merge-queue design looks correct and mergeable as-is.
Reviewed changes in this run: CI and skill updates preparing main for a GitHub merge queue.
Merge-group triggers: ci.yaml and check-pr-title.yaml now listen for merge_group (checks_requested); title jobs no-op (pass) off pull_request, with workflow_dispatch gated to tagpr-from-* branches.
Change detection on groups: detect-code-changes falls back to merge_group.base_sha, so a group diff conservatively covers every PR ahead in the group and errs toward full CI.
Skipped-but-required jobs: the tirith SARIF upload and perf comments skip on merge_group; ci gate treats skipped jobs as a pass, and the release-dispatch status jobs stay dispatch-only.
Release PR path: release.yaml now dispatches both ci.yaml and check-pr-title.yaml, so the tagpr release branch head carries the required title contexts even though its pull_request runs stall on approval.
Queue-compatible merging: Renovate switches to platformAutomerge: true, and the create-pr skill queues via plain gh pr merge with reporter credit moved to a Co-authored-by trailer on a PR commit.
This compares the PR package against the configured base package on the same CI runner.

Lower medians and smaller artifacts are better. CI runner noise still applies; use same-run ratios as directional PR feedback, not release guarantees.
Skipping the SARIF upload on merge_group lost the findings that matter
most there: when tirith blocks a queued commit, that commit never reaches
main, so no push run ever uploads them. Code scanning accepts uploads for
merge queue refs, so the upload runs for merge groups like any other
non-fork run.
The e2e comment no longer ties the queued commit's SHA to the one main
gets; what the queue verifies is the package built from that tree.
merge_group runs queued code with the permissions the workflow declares,
unlike fork pull_request runs, whose token GitHub caps at read. The native
build job declared `actions: write`, and its Nix build was handed the
GitHub token on every event except pull_request, so a queued fork PR's
build ran with both.
Nothing in the build job uses `actions: write`: artifacts and the Actions
cache authenticate with the runtime token, and cache-nix-action only needs
the API token to purge, which this repository does not do. The job now has
read-only permissions on every event. The Nix token is passed only on push
and workflow_dispatch, which build code already on main or a release
branch.

the prior squash strategy when it does not. Keep the explicit-user-request
condition for both paths.

Review comments at @.github/workflows/release.yaml:
- Line 63: Update the release workflow’s check-pr-title.yaml invocation so the
title validations run through a PR-eligible trigger on the tagpr-created release
PR. Do not rely on workflow_dispatch for required checks; ensure GitHub
associates the PR-triggered validation runs with the release PR’s head.

Reviewed changes in this run (delta since prior pullfrog review at c8898bc): least-privilege hardening for merge-group builds plus SARIF upload coverage.
Uploaded tirith findings for merge groups: the SARIF upload no longer skips on merge_group, so a tirith-blocked queued commit still publishes its findings even though it never reaches main.
Hardened native builds for queued code: the build job dropped actions: write to actions: read, and the Nix GitHub token is now passed only on push and workflow_dispatch, so pull requests and merge groups build with no token.
Clarified e2e preview wording: the comment now states the queue verifies the package built from the tree main will get, dropping the overstated same-SHA claim.
This compares the Rust PR release binary against the configured base package on the same CI runner.
Package runtime diagnostics
Compares the PR package wrapper, the installed native optional dependency binary, and the workspace release binary on the same large fixture. This identifies whether slow package results come from JavaScript wrapper overhead, the published native binary build, or the Rust core itself.
Fixtures: Claude /home/runner/_work/_temp/ccusage-large-fixture (1.01 GiB, 2597 files), Codex /home/runner/_work/_temp/ccusage-large-codex-fixture (1.01 GiB, 2597 files)
All rows run --offline --json, measured by hyperfine with 0 warmups and 1 runs. This isolates wrapper overhead from the installed native optional dependency and the workspace release binary built on the runner.

Lower medians and smaller artifacts are better. CI runner noise still applies; use same-run ratios as directional PR feedback, not release guarantees.
The native build and the pkg.pr.new publish jobs run code from the
checked-out commit, which on merge_group is queued code that has not
passed its checks yet. Their checkouts kept actions/checkout's default of
writing the job token into .git/config, where that code can read it.
Neither job pushes or fetches with credentials, so the token no longer
stays on disk.
Required checks are matched against what is attached to the pull
request, and GitHub does not attach check runs from workflow_dispatch
runs. Release PR #2018 shows it: its head commit carries the dispatched
CI's check runs, yet the PR's status rollup lists none of them, only the
`CI (release dispatch)` commit status. Under the new ruleset the release
PR would therefore stay blocked on `ci gate` and on both title checks,
whose dispatched check runs never reach it.
Commit statuses are attached by SHA, so the dispatched runs now report the
exact required contexts that way, using the Actions token so the status
comes from the GitHub Actions app the ruleset names. CI's existing
release status is renamed from `CI (release dispatch)` to `ci gate`, and
the title workflow posts `Validate PR title` and `Validate PR title scope`
from a separate job that runs no repository code. The two title jobs no
longer run on dispatch.
Without a merge strategy, `gh pr merge` fails in a non-interactive session
on a base branch with no merge queue: stacked PRs into feature branches,
and main until the ruleset is enabled. With a queue, gh only warns that the
queue sets the strategy and enqueues the PR, so `--squash` works on both.
`--delete-branch` is still left out, because gh rejects it when a queue is
required.

✅ No new issues found.
Reviewed changes in this run (delta since prior pullfrog review at ff840a0): release-PR status reporting plus checkout and skill hardening.
Stopped persisting checkout credentials in build jobs: the native-build and publish checkouts now use persist-credentials: false, so queued code cannot read the job token from .git/config; composite actions that need it still use the github.token expression directly.
Reported required checks as commit statuses for the release PR: ci.yaml now posts the gate result under the exact ci gate context (renamed from CI (release dispatch)), and a new release-pr-statuses job in check-pr-title.yaml posts both title contexts, since dispatch check runs never attach to the release PR.
Kept --squash in the merge skill: gh pr merge <pr> --squash without --delete-branch or --body-file works with and without a queue, with reporter credit moved to a Co-authored-by trailer on a PR commit.
This compares the Rust PR release binary against the configured base package on the same CI runner.

Lower medians and smaller artifacts are better. CI runner noise still applies; use same-run ratios as directional PR feedback, not release guarantees.
The perf job only runs on `pull_request`, and #2062, which adds the
`merge_group` trigger, keeps the perf comment PR-only, so the
`merge_group.base_sha` and `github.sha` fallbacks and the comment
promising merge_group support could never apply. Remove them.
Reported by Cubic on #2061.
The Nix sticky disks are keyed by job, not by ref, so pull request and
merge group runs mount the same disk main commits and release builds
read. What keeps their changes out of it is the stickydisk `commit` flag,
and setup-nix-cache derived that flag on its own from the ref. A
merge_group run checks out the queued commit, so that local action is the
queued code's own copy, and nothing in ci.yaml stated the rule.
ci.yaml now sets PERSIST_CACHES from `github.ref == 'refs/heads/main'` and
passes it to every Nix store and Cargo cache save. Non-main runs still
mount main's warm disk, so pull requests keep their cache hits, but they
mount it without committing and the clone is discarded.
This cannot stop a queued commit that edits ci.yaml itself; review before
queuing is that boundary. It stops a change to a local action, or an
unreviewed-code path, from writing a store that main reads.
The release PR's required checks are reported as commit statuses from
runs that release.yaml dispatches after tagpr updates the branch. A person
pushing to the `tagpr-from-*` branch moves the PR head without any
dispatch, so the new head had no `ci gate` or title statuses and the
release PR was blocked again.
tagpr pushes with GITHUB_TOKEN, which starts no workflow, but a person's
push does. CI and the title workflow now also run on pushes to
`tagpr-from-*`, and the same status jobs run for those pushes, so every
head the release PR can have gets the statuses. The trigger is not added to
release.yaml, because its `tagpr` concurrency group would let a
release-branch run replace a pending release run from main.
The branch-prefix check alone let anyone with write access dispatch the
title workflow from a `tagpr-from-*` branch they created and get both title
statuses on any commit. The job now posts them only when the commit is
the head of an open PR from that branch opened by github-actions[bot],
which is how tagpr opens release PRs.
This compares the Rust PR release binary against the configured base package on the same CI runner.

@ryoppippi I have started the AI code review. It will take a few minutes to complete.
The reason will be displayed to describe this comment to others. Learn more.
✅ No new issues found.
Reviewed changes in this run (delta since prior pullfrog review at 202cb8c): cache-persistence gating plus direct-push handling for the release branch.
Gated cache persistence on main only: added workflow-level PERSIST_CACHES (github.ref == 'refs/heads/main') and forwarded it as save/save-nix-cache/save-cargo-cache to every Nix, build, publish, and perf-disk step, so pull requests, merge groups, and release-branch runs mount the warm store without committing it.
Re-reported release statuses on direct pushes: extended ci.yaml and check-pr-title.yamlpush triggers to tagpr-from-* and widened the release-dispatch/status jobs to workflow_dispatch || push, so a person pushing to the release branch re-posts ci gate and both title contexts for the new head.
Hardened release title statuses: narrowed the title jobs to pull_request/merge_group (skipping PR-only validating steps where PR context is absent), added pull-requests: read for the PR lookup, and made release-pr-statuses fail closed unless the SHA is the head of an open tagpr PR from that branch opened by github-actions[bot].
This compares the Rust PR release binary against the configured base package on the same CI runner.

#2062 switched Renovate to GitHub auto-merge so dependency PRs could enter a
merge queue, since a required queue rejects Renovate's direct API merge. The
queue is not being enabled: the daily pricing workflow pushes straight to main
with the Actions token, and a ruleset cannot list the GitHub Actions integration
as a bypass actor. Without a queue or required checks, GitHub auto-merge adds
nothing over Renovate's own automerge, so restore the previous setting.
#2061)
* build(perf): shape the large fixture like current Claude Code and Codex logs
The CI performance comparison missed the double parse that #1719 added
to every Claude line containing `null`, because the generated fixture
never contained `null`: each line was a minimal assistant usage record
padded with a single text block of `x` characters. Real Claude Code
lines now carry `stop_sequence`, `container`, `stop_details` and other
null-valued fields, nested `usage.iterations` and cache-creation TTL
splits, and most lines are not usage records at all. On the old fixture
v20.0.20 -> v20.0.21 moved CPU time by +8%; on real-shaped lines it is
+55%.
The generator now writes sessions whose line types, per-type byte
share, and field shapes follow aggregate statistics taken from real
logs (structure only; every value is synthesized from a seeded PRNG,
so the output is deterministic):
- Claude: user/tool-result, attachment, api-request(-blob) and metadata
lines around assistant responses written one line per content block
with repeated usage, null-valued fields, `usage.iterations` including
occasional advisor iterations, 5m/1h cache-creation split, escaped
and non-ASCII text, 48 projects, sidechain `subagents/agent-*.jsonl`
files that replay parent message IDs, and legacy files with
`progress` lines wrapping AgentProgress assistant messages.
- Codex: dated `sessions/YYYY/MM/DD/rollout-*.jsonl` files with
session_meta, turn_context, reasoning, tool call/output and
item_completed lines, plus token_count (with null-heavy rate limits)
and token_usage_record per response. As in real Codex homes, rollouts
older than two weeks are zstd-compressed (`.jsonl.zst`) and some sit
in `archived_sessions/`; on real data about 90% of Codex bytes are
now read through zstd, a path the old fixture never touched.
The file-size distribution (of uncompressed bytes) and the CLI are
unchanged.
* build(perf): build base and PR from source and judge them by CPU time
The PR performance comment could not show a regression or a real
improvement:
- Unequal artifacts. Base ran the published `ccusage` npm package (Node
launcher spawning the native binary) while the Rust leg ran the bare
native binary, so every PR showed a ~2.6x "win" on the committed
fixtures that was only launcher startup.
- One sample. The large fixture ran with 0 warmups and 1 run, and the
base and PR runs were not interleaved, so runner noise dominated.
- The committed fixtures are a few KiB and measure process startup.
- No verdict. Nothing said whether a number was a regression.
The job now builds both binaries with `nix build .#ccusage-static`, the
derivation the Linux x64 native package ships, on the same runner: the
PR head from the checkout and the base from
`github.event.pull_request.base.sha`, the same base commit as before.
The walk back over pricing-only commits only existed to find a commit
with a pkg.pr.new package, so it goes. The job reuses the
build-native-packages sticky disk for dependency artifacts and no
longer waits for pkg.pr.new, so the JS launcher leg, the
committed-fixture section, and the package diagnostics are gone too.
The harness runs `claude daily`, `claude session`, `codex daily` and
the unified `daily` over the realistic generated fixture in interleaved
rounds (each round one hyperfine invocation with both binaries, order
rotated), recording wall time, CPU time, peak RSS and, where the
platform exposes it, instructions. It reports medians with min-max
spread and per-round PR/base ratios. A command is flagged when the
median CPU-time or peak-RSS ratio moves past 10% and at least four in
five rounds agree; the verdict line and a GitHub warning annotation say
so. Wall time is shown but not judged: it moves with runner load, while
CPU time paired within a round does not.
The check warns rather than fails: a failing check needs a calibrated
false-positive rate across many runs on these runners and an escape
hatch for intentional trade-offs, and neither exists yet.
* build(perf): add `just bench-history` to compare refs
Finding which release introduced a slowdown meant building each tag by
hand and timing it ad hoc. `just bench-history <ref|binary>...` builds
each ref in release mode into `rust/target/bench-history` (one shared
cargo target dir, binaries cached by commit), generates the realistic
fixture once per generator revision and size, and runs every report
command over all refs in the same interleaved rounds as the PR
comparison. Each ref is judged against the previous one with the same
CPU-time/peak-RSS rule, so a regression shows up at the step that
introduced it. `--real` adds a section over the logs the current
environment points at.
It reuses the PR harness modules instead of adding a parallel tool, and
the profile skill now points at it.
* fix(perf): print the regression annotation on stdout
GitHub Actions reads workflow commands only from stdout, but the
`::warning` line was printed while `*out*` was bound to `*err*`, so a
flagged regression never produced an annotation. Print it on stdout and
pass the GitHub Actions check in, so a test can assert the stream.
Reported by Pullfrog on #2061.
* fix(perf): reject bench-history runs below the minimum
`parse-history-cli` validated a copy with `:runs` raised to 3 but
returned the original options, so `--runs 2` passed validation and then
measured two rounds, too few for the four-in-five agreement rule.
Validate the options that are returned, so fewer than three rounds is
rejected as in the PR comparison, and say so in both `--runs` helps.
Reported by Pullfrog on #2061.
* fix(perf): run fixture benchmarks in an empty environment
The fixture runs pointed Claude and Codex at the fixture and moved HOME
and XDG_* to an empty directory, but every other agent has its own
data-dir variable (AMP_DATA_DIR, OPENCODE_DATA_DIR, PI_AGENT_DIR,
GEMINI_DATA_DIR and a dozen more), and a value set in the caller's shell
still pointed the unified `daily` report at real logs. Listing every
variable would rot as agents are added, so the fixture commands now run
under `env -i` with only the variables the run needs; with XDG_* unset
the agents fall back to the empty HOME. The local-logs mode keeps the
caller's environment on purpose.
Reported by Cubic on #2061.
* fix(perf): make bench-history safe to point at binaries and run twice
Four ways `just bench-history` could measure the wrong thing or fail:
- Binary-path variants were labelled by basename, so two builds at
`a/ccusage` and `b/ccusage` collided in hyperfine's results. Label
them by the argument as given, and reject a ref or path passed twice.
- `--fixture-dir` alone silently reused the Claude logs as the Codex
fixture. Require both directories or neither.
- The cached binary was copied without attributes; copy them so the
executable bit is kept on every platform.
- Every run checked refs out into the shared `<cache>/src` worktree and
removed it on exit, so a second run sharing the cache deleted the
first run's checkout mid-build. Each run now uses its own temporary
worktree; the shared cargo target is safe because cargo locks it.
The first three were reported by Cubic on #2061; the fourth showed up
while bisecting with two runs at once.
* fix(perf): report memory-only improvements and history instruction ratios
The overall verdict counted only CPU improvements, so a PR that cut
peak RSS read "no significant change" above a table saying "less
memory". Count CPU and RSS improvements alike and name what improved
per command. The history tables also dropped the instruction-count
ratio the PR comparison shows; add it as a column whenever hardware
counters are available.
Reported by Cubic on #2061.
* test(perf): restore duplicate-name and time-unit hyperfine cases
The hyperfine reader rewrite kept the missing-name and malformed-output
cases but lost the duplicate-name and non-second-unit ones, so a change
that accepted ambiguous or mis-scaled samples would pass. Restore both
against the new per-run reader.
Reported by Cubic on #2061.
* fix(perf): print the generated fixture's size on disk
With zstd-compressed Codex rollouts the generator's `Size` line showed
the uncompressed bytes, about four times what it wrote. Print the size
on disk from `Bun.write` and the uncompressed size separately.
Reported by Cubic on #2061.
* fix(ci): measure the PR merged onto its base commit
The job built the PR side from `pull_request.head.sha` and the base
from `pull_request.base.sha`. When a branch is behind its base, the two
binaries differ by the base's newer commits as well as the PR's own
change, and those commits show up as PR regressions or improvements.
Build the checked-out merge commit (`github.sha`) instead. It is the PR
applied on top of the base commit, so the diff measured is exactly the
PR. A step fails the job if the base is not an ancestor of the built
commit, so the report's "merged onto Base:" line always names what was
actually built. BASE_SHA/HEAD_SHA fall back to `merge_group.base_sha`
and `github.sha`, and the PR-comment step is limited to pull_request
events, so the job also works if a merge_group trigger is added.
Reported by CodeRabbit on #2061.
* fix(perf): cache built bench-history binaries atomically
`build-commit!` copied the release binary straight to the cache path
that later runs trust when it exists, so an interrupted copy left a
truncated binary that every later run reused. Copy to a `.partial`
sibling and rename it into place with an atomic move.
Reported by CodeRabbit on #2061.
* fix(perf): start fixture generation from an empty directory
A cached fixture without its `.complete` marker was regenerated into
the same directory, so files from an interrupted run could remain next
to the new output. Delete the directory first, so the marker always
describes exactly what the generator wrote.
Reported by CodeRabbit on #2061.
* fix(perf): order Codex usage records like real rollouts and add compactions
The generator wrote each response's `token_count` before its
`token_usage_record`. Real rollouts write the record first, and the
parser settles a pending record only when a later `token_count`
advances the cumulative total, so every synthetic record stayed in the
compaction pending map until the end of its file. That inflated peak
RSS in a way real logs never do: on the corrected fixture `codex daily`
peaks at 56 MiB on main instead of 69 MiB.
Write the record before the `token_count`, as Codex does, and add the
remote compactions real rollouts contain: about one turn in 30 ends
with a usage record whose usage is not in the cumulative total,
followed by a `compacted` marker naming it and carrying a large
replacement history. In real logs every marker names an earlier record.
Reported by Cubic on #2061.
* fix(ci): gate the perf job on preflight and keep its token read-only
The old perf job depended on the pkg.pr.new publish job and so, through
it, on `preflight` (secret scan and workflow lint); building from
source dropped that dependency, letting a PR that fails the scan run
the benchmark anyway. Depend on `preflight` directly.
The job also ran PR-built binaries, the fixture generator and the
harness with `pull-requests: write` and `issues: write`. Split it:
`ccusage-perf` builds and measures with a read-only token and uploads
the report, and `ccusage-perf-comment` downloads it and only runs the
comment upsert with the write token.
Reported by Cubic on #2061.
* fix(perf): lock bench-history builds and fixture generation
Runs sharing the cache could interleave writes: one build could replace
`target/release/ccusage` in the shared cargo target before another run
copied it into its commit's cache slot, and two runs could delete and
regenerate the same fixture under each other. Build-and-copy now runs
under a cache-wide file lock, and each fixture key under its own, both
re-checking the cache once they hold the lock. A per-commit target dir
would avoid the lock but rebuild every dependency for every ref.
The lock is a FileChannel lock released by closing the channel, and a
test runs three processes against it and checks their critical
sections never overlap.
Reported by Cubic on #2061.
* fix(ci): drop the perf job's unreachable merge_group fallbacks
The perf job only runs on `pull_request`, and #2062, which adds the
`merge_group` trigger, keeps the perf comment PR-only, so the
`merge_group.base_sha` and `github.sha` fallbacks and the comment
promising merge_group support could never apply. Remove them.
Reported by Cubic on #2061.
* fix(perf): give bench-history a Codex fixture every compared ref reads
The generated Codex fixture is mostly zstd-compressed rollouts, some in
`archived_sessions/`. Releases before #1890 skip `.jsonl.zst` files
(and before #1230 skip archived sessions), so a history run across
that change compared an old ref reading a fraction of the input with a
new ref reading all of it, and reported the difference as a CPU and
RSS regression.
The generator gains `--codex-layout legacy`, which writes the same
rollouts uncompressed under `sessions/`. bench-history keeps the
current layout when every ref is a commit containing #1890, and
otherwise generates the legacy layout and says so at the top of the
report; binary paths count as unknown. With a custom Codex fixture
that holds `.zst` files and a ref that cannot read them, and for
`--real` runs across the change, the report leads with a warning
instead. The PR comparison always builds refs that read the current
layout, so CI keeps compressed coverage.
Reported by CodeRabbit on #2061.
* fix(perf): check every Codex input class a compared ref may skip
The compatibility check only looked for `.jsonl.zst` files, but
releases before #1230 also skip `archived_sessions/`, so a custom
fixture with archived plain rollouts got no warning and a history run
across #1230 compared different input.
Replace the single zstd commit with a table of Codex input classes taken
from the Codex loader's history (`paths.rs`, `reader.rs`): archived
sessions (a9b12c4, #1230, v20.0.7) and zstd-compressed rollouts
(44a3aa8, #1890, v20.0.33). Each ref is checked per class by git
ancestry; the generated fixture switches to the legacy layout when any
ref skips any class, and a custom fixture or `--real` run warns per
class with the refs that skip it. Claude discovery has scanned
`projects/` recursively throughout v20 and the date-window skips (#1665,
#1794) do not apply to unbounded reports, so they are not classes.
Probing each ref's source for the reader code was rejected: the same
strings appear in tests and comments.
Reported by Cubic on #2061.
* fix(ci): run the perf comment upsert from the base commit
The comment job holds `pull-requests: write` and `issues: write`, but it
checked out the PR merge commit and ran that tree's setup action and
`upsert-pr-comment.nu`, so a PR that edited either ran them with the
write token. Check out `pull_request.base.sha` instead, still without
persisted credentials. The PR's report reaches the job only as an
artifact the script reads as text.
This PR does not change `upsert-pr-comment.nu`, and the base version
reads the same inputs (COMMENT_FILE as raw markdown, COMMENT_MARKER,
PR_NUMBER, GITHUB_REPOSITORY, GITHUB_TOKEN), so the first runs after
merge need no fallback.
The workflow file itself still comes from the PR on `pull_request`
events, so this removes the PR's scripts from the write job rather than
making the job a hard trust boundary.
Reported by CodeRabbit on #2061.
* fix(perf): match Codex input classes to the rollouts the loader reads
The input-class matchers looked at absolute paths: any `.zst` file
counted as a compressed rollout, and any path containing
`/archived_sessions/`, including a parent of the fixture, counted as
an archived session. Match paths relative to the Codex home against
what the loader reads: `*.jsonl` and `*.jsonl.zst` (reader.rs) under
`sessions/` and `archived_sessions/` (paths.rs). Tests cover
non-rollout `.zst` files, rollouts outside those directories,
non-rollout files in `archived_sessions/`, and a fixture under a
directory named `archived_sessions`.

Fork wins kept: the Codex optimized scanner with its fork-replay instant,
the Antigravity model resolver, the OpenCode retained-ledger cache with its
per-namespace rows, the SQLite on-disk cache, the table renderer, the fork
CI and tag-only release workflow, and the exact `=` dependency pins.
Hand-resolved conflicts:
rust/adapters/claude/src/lib.rs: the fork's DedupedEntries copy pairs stay
and take upstream's carries_more_usage_detail tiebreak (speed rank, then
a cache TTL split); main_thread_session_days reads the recorded session
of each copy.
rust/adapters/opencode/{loader,parser}.rs: the fork's retain_via_ledger
stays beside upstream's v2 compaction scan; SessionMessageKind and
MessageRowColumns carry the row type through the five-value scan.
rust/adapters/codex/{replay,parser}.rs: open_rollout_reader_with_capacity
and CodexForkReplay both land in the shared parser state.
rust/crates/ccusage-core/src/{cache,pricing}.rs: the opencode-db-compaction
namespace joins the ledger namespaces; the fork's embedded pricing loader
and OnceLock path stay.
rust/crates/ccusage/src/cli/timezone.rs: Cline joins the shared-args arm,
the ClearCache arm stays unreachable from the parser.
rust/Cargo.toml: the fork's exact `=` pins stay; jiff 0.2.41,
schemars 1.2.2, serde 1.0.229, smallvec 1.16.5, toml 1.2.1.
.github/workflows/{ci,release}.yaml: the fork's design is kept, including
its own release flow. Upstream's merge-queue, tagpr and pkg.pr.new jobs
need scripts this fork deleted, so they are not taken; the two
save-nix-cache inputs upstream passes to the native-package actions are
dropped because the fork's composite actions declare no such input.
packages/ccusage-*/package.json (6 files), the contribution-gate scripts,
sponsors.md, blacksmith.png and rust/adapters/claude/src/daily.rs stay
deleted; the two Blacksmith SVG logos upstream added are not taken.
Docs: the agent lists take upstream's Cline addition but keep this fork's
`pi` name, because the CLI subcommand is still `pi`; upstream renamed the
docs to `pi-agent` without renaming the command.
Snapshots regenerated for the fork table renderer: the Cline adapter, CLI
and unified reports, codex issue_2046, opencode compaction, claude session
--id and the config schema (new Cline section).
Validation: cargo test --workspace --offline 1297 passed, 0 failed; cargo
clippy --workspace --all-targets clean; rustfmt --check clean.
Version: take upstream's 20.0.50 in package.json, apps/ccusage/package.json
and docs/package.json; the Rust workspace keeps version 0.0.0.
DO NOT push a v20.0.50 tag from this fork: release.yaml would publish fork
bytes under upstream identity.

Prepares the workflows for a GitHub merge queue on
main, ahead of a ruleset that requiresci gate,Validate PR titleandValidate PR title scope.Root cause
A merge queue merges a group only after the required checks report on the merge group's commit. Those checks come from workflows that listen for
merge_group. Today neitherci.yamlnorcheck-pr-title.yamldoes, so every queued PR would wait until the queue's timeout and drop out. A few things also assume a pull request or a direct merge:detect-code-changestakes its base frompull_request.base.sha || event.before. Neither exists onmerge_group, so it would diff from the root commit.GITHUB_TOKEN, so itspull_requestruns wait for an approval and never report. Its CI comes from aworkflow_dispatchinrelease.yaml, but GitHub does not attach check runs from a dispatch to a PR. chore: release v20.0.49 #2018's head commit has the dispatched CI's check runs, yet its PR status rollup lists none of them, only theCI (release dispatch)commit status. Onceci gateand the title checks are required, every release PR would be blocked.platformAutomerge: false), and GitHub rejects direct merges when a queue is required.create-prskill merges withgh pr merge --squash --body-fileto addCo-authored-byfor issue reporters. The queue builds its own squash message, so that body would be dropped.Design
ci.yamlListens for
merge_group(checks_requested).detect-code-changesdiffs fromgithub.event.merge_group.base_sha. For a group with several PRs, that diff covers every PR ahead in the group, which errs on the safe side.Still running on
merge_group: tirith scan and its SARIF upload, preflight, test, native builds, the pkg.pr.new publish and the e2e matrix. pkg.pr.new records anyworkflow_run, not only PR runs, and keys a non-PR publish by the checked-out SHA. So the queue publishes a preview of the merge group commit, and e2e installs the package built from the treemainwill get. No PR comment is posted, because the run is not tied to a PR.The SARIF upload keeps running on
merge_group, because a commit that tirith blocks in the queue never reachesmain, so no push run would publish its findings. Code scanning accepts uploads from merge queue refs; codeql-action's own workflows upload onmerge_group.Skipped on
merge_group: the perf comments, which were already limited topull_request.ci gatetreats a skipped job as a pass.Least privilege for queued code. A
merge_grouprun gets the permissions the workflow declares, whereas GitHub caps a fork PR'spull_requesttoken at read. The native build job no longer hasactions: write, which nothing used: artifacts and the Actions cache authenticate with the runtime token, and cache-nix-action needs the API token only to purge caches. The job now hasactions: readandcontents: readon every event. Its Nix build gets the GitHub token only onpushandworkflow_dispatch, so pull requests and merge groups build without it. Every job a merge group runs now has a read-only token, apart from the SARIF upload'ssecurity-events: write, which runs only pinned actions.Only
mainpersists caches, andci.yamlmakes that decision itself. A workflow-levelPERSIST_CACHES: ${{ github.ref == 'refs/heads/main' }}is passed to every Nix store and Cargo cache save. The Nix sticky disks are keyed by job, not ref. Pull requests and merge groups therefore mountmain's warm disk withcommit: false, so the clone is discarded. Before, onlysetup-nix-cachedecided this, and onmerge_groupthat local action comes from the queued commit. Limit: a queued commit that editsci.yamlitself can still change this. Review before queueing is that boundary. The gate stops a changed local action, or code nobody reviewed, from writing a storemainreads.ci.yamlhas noconcurrencygroup, and nothing readshead_refor a PR number outside the perf-comment job.The build and publish checkouts no longer persist the job token into
.git/config, where the code they run could read it.check-pr-title.yamlmerge_group. Both jobs keep their names so the check contexts stay the same, and run their real steps only onpull_request. Onmerge_group, a no-op step reports success: the group is built only from PRs whose titles already passed. The scope job's label exemptions apply only onpull_request, so it is never skipped onmerge_group.Release PR (

That works with and without a queue: with one, gh warns that the queue sets the strategy and enqueues the PR.
