## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Required CI checks protect changes to its native Runner and control plane. > - Recent Runner jobs restored a Rust cache but still rebuilt dependencies for 74–92 seconds. > - New workspace install hooks disabled the materialized JavaScript dependency cache. > - A single transport file also kept 326 test cases on one worker. > - This pull request corrects the cache inputs, replays known install hooks, and separates independent transport test groups. > - The same checks can finish sooner without removing test cases or widening runner access. ## Linked Issues or Issue Description Refs #18794 and #18544. Related dependency-action version update: #17698; this change fixes the cache input contract used by the currently pinned action. **What happened?** Recent PR jobs such as #18783 and #18825 restored an exact Rust dependency cache from October 16. The virtual workspace's development profile changed on October 30. Rust Cache 2.9.2 hashes member manifests but omits that virtual manifest. Rebuilding cannot replace an immutable exact cache entry. The JavaScript cache also rejected the new server and Runner Copilot postinstall hooks. **Expected behavior** Changing a Cargo profile selects a new dependency cache. An exact JavaScript dependency restore still performs required workspace install hooks. Independent transport fixtures use the existing file workers while retaining all assertions and real deadlines. **Steps to reproduce** Inspect the Rust dependency cache hit and following `build:rust` in the recent Runner package jobs. Run `node scripts/ci-dependency-cache.mjs` on the previous revision to see `cacheable: false`. Run the original transport file to measure the serial test work. ## What Changed - Add the virtual workspace manifest and ancestor Cargo configuration to all shared Rust dependency keys. Keep reader/writer identities aligned and preserve master-only cache writes and CODEOWNERS-only AWS routing. - Recognize only the exact reviewed root, server, and Runner postinstall commands. Include the server/Runner installer scripts in the dependency key. Replay workspace postinstall hooks after a materialized restore. Unknown lifecycle hooks still disable reuse. - Move attachment recovery, warm attachment, live adoption, and suspension fixtures into separate files. Keep the large event-backlog cases in the original file to avoid starting another expensive fixture group at the same time. Share five stateless test helpers outside production source. - Extend the opt-in `profile-ci` benchmark with a PR-scoped Rust cache producer and a fresh-host consumer. Require exact dependency/workspace hits and reject any Cargo unit that is rebuilt. Retain the JSON build evidence. Existing setup qualification checks real JavaScript cache restores. - Schedule the ten measured files over 50 seconds first, in approximate duration order. Package CI uses up to four workers, bounded by available CPUs; local runs retain Vitest defaults. The AWS runner has four CPUs and 16 GiB RAM; the three-worker run averaged 44% CPU and peaked at 15% memory. Preserve Vitest selection and shard membership and default ordering for other files. Job count and AWS authorization are unchanged. - Scope the optional paired server benchmark to changes in its measured inputs. Cache-only changes qualify exact restores and run the shared package tests using restored dependencies. - Update the cache and test documentation and the existing native cache contract guard. ## Verification - All 586 `.github/scripts/tests/*.test.mjs` policy tests passed, including cache trust and runner routing guards. Actionlint passed for all three changed workflows. - All 169 original top-level transport test definitions remain byte-identical. The original file passed all 326 cases in 317.99 seconds on this macOS host. A clean preliminary split passed the exact same named cases in 183.01 seconds with the same four-worker cap. - Preserve the first failed experiment: its parallel run overlapped the policy suite and timed out in the 1,024-event settled backlog case at 60 seconds; 325 cases passed. A clean repeat passed, but that does not establish the earlier failure's sole cause. The final layout keeps the backlog cases in the original file. The final layout passed the same 326 cases in 186.35 seconds (41.4% faster than the 317.99-second baseline). The original test bodies and all timeouts remain unchanged. - Fresh-host Rust qualification passed: all 308 compilation units were fresh, and Cargo completed in 1.59 seconds on a new runner ([final-head run](https://github.com/paperclipai/paperclip/actions/runs/41745082837/job/126296908816)). JavaScript setup dropped from 46 seconds cold to 23 seconds with exact dependency/build restores; all 1,052 shared-package cases passed against the restored tree ([final-head job](https://github.com/paperclipai/paperclip/actions/runs/41745082837/job/126295937797)). The previous qualification also passed (43 to 19 seconds) and confirmed all three postinstall hooks replayed. These are qualification results, not an end-to-end PR timing claim. - Initial full AWS package run passed 4,907 cases with 10 existing skips. The original-file remainder fell to 118.7 seconds, but the 100-second deadline file started last, leaving the full package at 417.43 seconds. Starting only three long files first passed 4,911 cases (including four new sequencer guards) in 422.54 seconds, so reordering alone did not improve full-package time. Summed file execution was 1,202 seconds across three busy workers. The final four-worker configuration passed **4,912 cases, with the same 10 existing skips**, in **324.99 seconds**, a **23.1% reduction** from 422.54 seconds. The five added cases guard ordering, selection, sharding, and path handling. Peak memory was 17.95% of the 16 GiB runner; average CPU was 49.14% ([final-head package job](https://github.com/paperclipai/paperclip/actions/runs/41745082974/job/126296339480)). - Local workspace typecheck and build passed. The complete local `pnpm test:run` passed all six chat partitions but reported failures in one existing OAuth redirect case and one gateway authority case in the general-server group. Both focused repetitions passed (three OAuth cases and one gateway case), and a complete repeat of both files passed all 593 cases in 42.89 seconds; that does not explain the original failures. The broad local run was stopped after 61 minutes once full final-head CI had passed; its remaining general/workspace/serialized work was not completed locally, and it is not reported as a pass. Original failure logs were retained. Full final-head CI provides the complete suite validation. Sequencer selection/shard guards and the 11-case transport suspension smoke passed. The corrected release workflow guard passed all 71 tests. - The first CI run failed only the policy guard that still expected the old native cache key; downstream aggregate checks also failed. That guard now checks the new profile/config prefix and existing host/target/protocol suffix. A second policy run found that the new sequencer test imported Vitest in the dependency-free policy lane; it now runs in the Runner package lane, where all four cases pass. Greptile reviewed final head `8011f84189` at 5/5 with no actionable findings and confirmed this issue fixed. Final-head policy, typecheck, build, and review passed. At 23:52:46 UTC on November 3, several AWS jobs were terminated together: the Runner package process received SIGTERM and browser logs recorded a runner shutdown signal. The failed/cancelled jobs passed on the same-head retry, including required `ci / verify`; no assertion or timeout was changed in response. The final concurrency adjustment at `fe5a69bb0b` also received Greptile 5/5 with no actionable findings. Final-head required CI, including `ci / verify`, passed ([aggregate](https://github.com/paperclipai/paperclip/actions/runs/41745082974/job/126300554711)). Local timings exclude install, build, cache transfer, and CI queue time. ## Risks A new Rust key needs one successful canonical master build before ordinary PRs can hit it. The fresh-host qualification uses separate PR-scoped entries. Parallel test files can increase I/O contention; case execution inside each file, timeouts, and assertions are unchanged. Two extracted suites exceed 1,000 lines because they retain existing multi-stage recovery fixtures unchanged; one parameterized fixture alone is 1,059 lines. No production execution logic, lockfile, credentials, runner trust gates, or required check is removed. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository editing, command execution, and GitHub inspection.

Release Automation Setup
This document covers the GitHub and npm setup required for the current Paperclip release model:
- automatic canaries from
master - manual stable promotion from a chosen source ref
- npm trusted publishing via GitHub OIDC
- protected release infrastructure in a public repository
Repo-side files that depend on this setup:
.github/workflows/release.yml.github/CODEOWNERS
Note:
- the release workflows intentionally use
pnpm install --no-frozen-lockfile - this matches the repo's current policy where
pnpm-lock.yamlis refreshed by GitHub automation after manifest changes land onmaster - the publish jobs then restore
pnpm-lock.yamlbefore runningscripts/release.sh, so the release script still sees a clean worktree
1. Merge the Repo Changes First
Before touching GitHub or npm settings, merge the release automation code so the referenced workflow filenames already exist on the default branch.
Required files:
.github/workflows/release.yml.github/CODEOWNERS
2. Configure npm Trusted Publishing
Do this for every public package that Paperclip publishes.
At minimum that includes:
paperclipai@paperclipai/server@paperclipai/ui- public packages under
packages/
2.1. In npm, open each package settings page
For each package:
- open npm as an owner of the package
- go to the package settings / publishing access area
- add a trusted publisher for the GitHub repository
paperclipai/paperclip
2.2. Add one trusted publisher entry per package
npm currently allows one trusted publisher configuration per package.
Configure:
- workflow:
.github/workflows/release.yml
Repository:
paperclipai/paperclip
Environment name:
- leave the npm trusted-publisher environment field blank
Why:
- the single
release.ymlworkflow handles both canary and stable publishing - GitHub environments
npm-canaryandnpm-stablestill enforce different approval rules on the GitHub side
2.2.1. Newly added public packages need a bootstrap phase
Trusted publishing is configured on the npm package itself, not at the repo scope. That means a brand-new public package must not be auto-enrolled into CI publishing until its npm package exists and its trusted publisher has been configured.
Repo policy:
- add every non-private package to
scripts/release-package-manifest.json - set
"publishFromCi": trueonly when CI is expected to publish that package - if the package is not ready for CI publishing yet, keep
"publishFromCi": false - complete the package bootstrap before merging any PR that changes a release-enabled new package
Bootstrap sequence for a new package:
- publish the package once from a trusted maintainer machine using normal npm auth
- open that package on npm and add the
paperclipai/papercliptrusted publisher for.github/workflows/release.yml - rerun or dry-run the release flow as needed to confirm CI publishing now works
- only then enable
"publishFromCi": true
PR CI enforces this by checking changed release-enabled package manifests against npm. That keeps master canary publishing healthy while preserving the no-long-lived-token model for normal CI releases.
2.3. Verify trusted publishing before removing old auth
After the workflows are live:
- run a canary publish
- confirm npm publish succeeds without any
NPM_TOKEN - run a stable dry-run
- run one real stable publish
Only after that should you remove old token-based access.
3. Remove Legacy npm Tokens
After trusted publishing works:
- revoke any repository or organization
NPM_TOKENsecrets used for publish - revoke any personal automation token that used to publish Paperclip
- if npm offers a package-level setting to restrict publishing to trusted publishers, enable it
Goal:
- no long-lived npm publishing token should remain in GitHub Actions
4. Create GitHub Environments
Create three environments in the GitHub repository:
npm-canarynpm-betanpm-stable
Path:
- GitHub repository
SettingsEnvironmentsNew environment
5. Configure npm-canary
Recommended settings for npm-canary:
- environment name:
npm-canary - required reviewers: none
- wait timer: none
- deployment branches and tags:
- selected branches only
- allow
master
Reasoning:
- every push to
mastershould be able to publish a canary automatically - no human approval should be required for canaries
The scheduled nightly lane also publishes under npm-canary: it is the same
trust level (fully automated, no human gate), its runs execute on master so
the branch rule is satisfied, and reusing the environment means the nightly
lane required no new environments and no npm trusted-publisher changes
(publishing still happens from release.yml, see section 2.2).
5.1. Configure npm-beta
Recommended settings for npm-beta:
- environment name:
npm-beta - required reviewers: at least one maintainer
- prevent self-review: enabled when your team size allows it
- wait timer: none
- deployment branches and tags:
- selected branches only
- allow
master
Reasoning:
- beta promotions are deliberate human decisions; the required reviewer on this environment is the promotion gate
- create this environment before the first
channel: betadispatch. If the workflow runs first, GitHub auto-creates the environment with no protection rules, and that first beta would publish without approval
Like nightly, beta publishing lives in release.yml, so no npm
trusted-publisher changes are needed (see section 2.2).
6. Configure npm-stable
Recommended settings for npm-stable:
- environment name:
npm-stable - required reviewers: at least one maintainer other than the person triggering the workflow when possible
- prevent self-review: enabled
- admin bypass: disabled if your team can tolerate it
- wait timer: optional
- deployment branches and tags:
- selected branches only
- allow
master
Reasoning:
- stable publishes should require an explicit human approval gate
- the workflow is manual, but the environment should still be the real control point
7. Protect master
Open the branch protection settings for master.
Recommended rules:
- require pull requests before merging
- require status checks to pass before merging
- require review from code owners
- dismiss stale approvals when new commits are pushed
- restrict who can push directly to
master
At minimum, make sure workflow and release script changes cannot land without review.
8. Enforce CODEOWNERS Review
This repo now includes .github/CODEOWNERS, but GitHub only enforces it if branch protection requires code owner reviews.
In branch protection for master, enable:
Require review from Code Owners
Then verify the owner entries are correct for your actual maintainer set.
Current file:
.github/CODEOWNERS
If @cryppadotta is not the right reviewer identity in the public repo, change it before enabling enforcement.
8.1. Let the Lockfile Bot Merge Lockfile Refreshes
.github/workflows/refresh-lockfile.yml regenerates pnpm-lock.yaml from the manifests on master and merges the result without CI or review. Contributors never commit the lockfile, so the bot is the only path for lockfile changes.
Resolution keeps locked versions, but it picks the newest matching version for an added or widened dependency. A release-age gate (.github/scripts/check-lockfile-release-age.mjs) therefore checks every package version that the refresh adds. The bot merges only when each one has been on npm for at least 3 days. If any version is newer, or the gate cannot verify it, the bot leaves a comment on the PR and does not merge. A maintainer can review and merge it, or the daily scheduled refresh merges it after the versions are old enough. A held run saves its lockfile, and the hash of the master lockfile it started from, as an artifact. The next run resolves from that lockfile only while master still has the same lockfile. Held versions therefore stay put while their manifests are unchanged, even when newer releases appear, and a lockfile change on master replaces them. The gate also holds any added entry whose resolution is not a plain npm registry tarball. Change the age with --min-age-days in the workflow.
The merge uses a dedicated GitHub App. Do not reuse commitperclip or bypass the built-in github-actions app. Those identities are available to other workflows, including release jobs that run dependency install scripts, so a bypass for them would let any of those workflows land code on master.
- Create an organization-owned GitHub App, for example
paperclip-lockfile-bot:- Disable the webhook.
- Repository permissions:
Contents: Read and write,Pull requests: Read and write. Leave everything else atNo access. - Allow installation only on this account.
- Install the app on
paperclipai/papercliponly. - Create a GitHub environment named
lockfile-refresh. Under deployment branches and tags, allow onlymaster. Add no required reviewers. - In that environment, add:
- variable
LOCKFILE_BOT_CLIENT_ID: the app's client ID - secret
LOCKFILE_BOT_PRIVATE_KEY: a private key generated for the app
- variable
- In the
masterruleset, add the app as a bypass actor with bypass modeFor pull requests only. The app can then merge PRs past required checks and code owner review, but it cannot push tomasterdirectly.
The workflow mints the app token after dependency resolution finishes and merges only the commit it pushed (--match-head-commit). A commit anyone else pushes to chore/refresh-lockfile makes the merge fail.
9. Protect Release Infrastructure Specifically
These files should always trigger code owner review:
.github/workflows/release.ymlscripts/release.shscripts/release-lib.shscripts/release-package-map.mjsscripts/create-github-release.shscripts/rollback-latest.shdoc/RELEASING.mddoc/PUBLISHING.md
If you want stronger controls, add a repository ruleset that explicitly blocks direct pushes to:
.github/workflows/**scripts/release*
10. Do Not Store a Claude Token in GitHub Actions
Do not add a personal Claude or Anthropic token for automatic changelog generation.
Recommended policy:
- stable changelog generation happens locally from a trusted maintainer machine
- canaries never generate changelogs
This keeps LLM spending intentional and avoids a high-value token sitting in Actions.
11. Verify the Canary Workflow
After setup:
- merge a harmless commit to
master - open the
Releaseworkflow run triggered by that push - confirm it passes verification
- confirm publish succeeds under the
npm-canaryenvironment - confirm npm now shows a new
canaryrelease - confirm a git tag named
canary/vYYYY.MDD.P-canary.Nwas pushed
Install-path check:
npm install --prefix "$(mktemp -d)" paperclipai@canary --no-audit --no-fund
The release script runs this clean-prefix install after publishing every workspace
package dependency-first and publishing paperclipai last. A package that is not
yet registry-visible stops the train before the channel entrypoint can advance.
12. Verify the Stable Workflow
After at least one good canary exists:
- resolve the target stable version with
./scripts/release.sh stable --date YYYY-MM-DD --print-version - prepare
releases/vYYYY.MDD.P.mdon the source commit you want to promote - open
Actions->Release - run it with:
source_ref: the tested commit SHA or canary tag source commitstable_date: leave blank or set the intended UTC date like2026-03-18do not enter a version like2026.318.0; the workflow computes that from the datedry_run:true
- confirm the dry-run succeeds
- rerun with
dry_run: false - approve the
npm-stableenvironment when prompted - confirm npm
latestpoints to the new stable version - confirm git tag
vYYYY.MDD.Pexists - confirm the GitHub Release was created
Implementation note:
- the GitHub Actions stable workflow calls
create-github-release.shwithPUBLISH_REMOTE=origin - local maintainer usage can still pass
PUBLISH_REMOTE=public-ghexplicitly when needed
13. Suggested Maintainer Policy
Use this policy going forward:
- canaries are automatic and cheap
- stables are manual and approved
- only stables get public notes and announcements
- release notes are committed before stable publish
- rollback uses
npm dist-tag, not unpublish
14. Troubleshooting
Trusted publishing fails with an auth error
Check:
- the workflow filename on GitHub exactly matches the filename configured in npm
- the package has the trusted publisher entry for the correct repository
- the job has
id-token: write - the job is running from the expected repository, not a fork
Stable workflow runs but never asks for approval
Check:
- the
publishjob uses environmentnpm-stable - the environment actually has required reviewers configured
- the workflow is running in the canonical repository, not a fork
CODEOWNERS does not trigger
Check:
.github/CODEOWNERSis on the default branch- branch protection on
masterrequires code owner review - the owner identities in the file are valid reviewers with repository access

Runner verification dependency cache
release-verify.yml runs Verify Paperclip Runner on two independent runners.
The protocol lane runs check:eval-kernel and check:protocol. The Rust lane
runs check:runner and check:api-authority. Together they retain every check
in check:all; both lanes must pass before Cloud source verification or
readiness can succeed. A failed lane does not cancel the other lane.
Both lanes restore Cargo dependencies with the pinned Rust Cache action. The
compiler comes from the Runner package's rust-toolchain.toml before the action
computes its key. Compiler and Cargo metadata changes select a new cache. The
release-runner-v2 shared key avoids separate copies for these lanes. Its suffix
hashes the virtual workspace's runner/Cargo.toml and ancestor Cargo configuration.
Rust Cache discovers member manifests through Cargo metadata, which omits this
virtual manifest. Without the suffix, changing [profile.dev] can restore an
exact but obsolete dependency cache on every run. GitHub caches are immutable,
so the successful rebuild cannot replace that old entry. The profile/configuration
hash also partitions fallback restores. Every reader and writer uses the same
inputs, including the separate typecheck and cross-target caches.
Only the Rust lane saves this cache. After verification it also runs build:rust
to warm the debug dependencies used by the protocol lane; its own tests already
warm release dependencies. The cache writer is shorter than the protocol lane.
GitHub matches a cache entry on its key and on a version hash of the absolute
paths in the entry. The master writer runs on the RunsOn fleet, where the
checkout is /home/runner/_work/paperclip/paperclip. The trusted PR workflow
restores the same entry read-only on GitHub-hosted runners, where the checkout
is /home/runner/work/paperclip/paperclip. A Pin the Runner Rust workspace path step in both workflows links $HOME/paperclip-runner-rust to the Runner
crate and passes that path to the cache action, so both layouts hash the same
paths and the PR lanes can restore master's entry. The guard tests under
.github/scripts/tests/ require this step, with identical text, before every
Rust cache step in both workflows.
Workspace crates and installed Cargo binaries are excluded from this entry. Every run runs all assigned checks, including on a cache hit. In release verification, only an own-repository master-push run verifying that push's exact SHA can restore the cache, and only a successful Rust lane saves it. The PR workflow restores master's cache read only. Tag and manual candidate release verification compile without this cache. A miss or eviction costs compilation time but does not change the checks. To discard old dependency caches, increment the shared-key version and let the next successful master verification warm it.
Installed JavaScript dependencies
setup-ci-dependencies can restore exact node_modules trees and separately
certified shared/SDK build outputs. scripts/ci-dependency-cache.mjs hashes
manifests, resolution, patches, install scripts, and the runtime/checkout layout.
The root workspace-link hook and the server/Runner Copilot asset hooks are known
postinstall commands. An exact dependency restore replays these hooks before
validating workspace links and build outputs. Copilot defers installation in an
unbuilt source checkout; its normal build installs and verifies the assets.
Provider assets are not included in the dependency cache. Any unrecognized
workspace lifecycle hook still disables materialized reuse. Only a frozen install
from the canonical master push can publish the shared entries.
For CI cache changes, the profile-ci label runs the paired setup benchmark
and exercises restored dependencies with the shared-package tests. The longer
server test comparison runs when its measured scripts or fixtures change;
cache-only changes do not require unchanged test commands to run faster.
It also builds Rust units on one GitHub-hosted runner and restores the dependency
and workspace caches on a second runner with a fresh checkout. Both restores
must be exact, and Cargo must report every unit as fresh. These qualification
caches are scoped to the PR and run; they cannot populate master's caches.
Runner release crate cache
The dependency entry leaves the Runner's own crate out, and a fresh checkout
invalidates cargo's mtime fingerprints for workspace crates anyway, so every
pull request build compiled paperclip-runner-core in release mode from
scratch (28-49s per job on 2026-10-11) although most master commits leave its
inputs untouched. A second, content-addressed entry holds only that crate's
release artifacts: its fingerprints, the lib's rlib and rmeta, the
paperclip-runnerd binary and their dep-info, about 70 MB. The path list and
the key inputs live in scripts/runner-release-crate-cache.mjs, which both
workflows call, and scripts/__tests__/runner-release-crate-cache.test.mjs
holds the readers and the writer to them.
The key is runner-release-crate-v1-<scope>-<hashFiles>. The scope names the
platform, the pinned compiler (rustc --version --verbose: release, commit and
host) and a hash of the checkout root, because cargo's dep-info records the
protocol files the crate includes by relative path as absolute paths. The
hashFiles part covers every input the build reads: the toolchain pin, the
manifests and lockfile, the crate sources, the protocol schemas and fixtures,
and the three fixture trees the test modules include (two under the Runner
package and tests/runner-e2e/fixtures at the repository root). Any change
to any of them selects a new key. A guard test resolves every include_str!
and include_bytes! in the crate, whether its argument is a literal or a
concat! of literals, env!("CARGO_MANIFEST_DIR") and macro metavariables,
and fails on an include that lands outside these patterns or uses a form it
cannot resolve. Readers pass no restore-keys: a prefix match would hand
cargo another revision's output.
The writer is the Rust lane of the same master-push verification, after its
checks and the debug warm-up. It looks the key up first and, on a miss, runs
cargo clean --release -p paperclip-runner-core and then the package's
build:binary (the exact command the readers run) before saving, so the entry
carries no test-profile variants. In the trusted PR workflow, the Typecheck,
Build and Canary Dry Run jobs and the two Verify Paperclip Runner lanes that
build the crate (rust and the final vitest shard) restore the entry
read-only right after the dependency restore. On a hit, mark-current sets
the mtime of every restored artifact to now, so cargo's freshness check sees
every source as older than the build and keeps the artifacts. A restore that
lacks any file cargo reads or checks for either unit (the fingerprint hash
and dep-info of each unit, the lib's rlib and rmeta, the binary under
deps; measured with cargo 1.97.1, which recompiles without any one of
them and recreates the uplifted binary without any of the rest) is removed
instead, the job log names the missing file, and cargo compiles as on a
miss. pnpm build
then prints Finished release profile in well under a second for that crate.
On a miss nothing changes: cargo compiles the crate as before.
The trust boundary is unchanged: only master writes, a pull request can only restore master's entry, and it restores only artifacts built from inputs byte-identical to its own merge tree.
The trust boundary is the protected master branch, not the cache-key text. GitHub does not let master restore caches created by a child branch, sibling branch, tag, or PR merge ref. Both permitted restore scopes (current branch and default branch) are master here. A workflow with authority to execute arbitrary code on master can affect verification directly and is already trusted. The cache contains dependency build artifacts, not credentials or workspace output. See GitHub cache access restrictions.
Chat integration test shards
Release verification runs the large chat integration file on three independent
runners. Five other server shards cover every remaining general server file.
The ordinary local test command and trusted PR workflow keep their complete
general-server group. Each chat case shuts down its services, pauses its own
still-active endpoints, and retires its active/waiting conversations after
assertions. This keeps workers in later cases from claiming earlier
fixtures in the shared test database. Application assertions stay unchanged.
Each chat job collects active tests with Vitest, groups cases by source line, and balances those groups by case count. Parameterized cases and loop-generated cases on one line stay together. The job re-collects with the exact line filters it will execute and fails if the selected case identities differ. Hooks and test execution remain sequential inside each runner with its own temporary home.
Run one shard locally with:
pnpm test:run:general -- --group general-chat --shard-index 0 --shard-count 3
Use indexes 0, 1, and 2 to run the complete chat suite. The CLI validates that each shard has work and that collection includes usable source locations. A Vitest collection or filtering change fails verification instead of dropping tests. Splitting adds three release-verification jobs and repeats collection and fixture setup; it does not make a single test faster.
The file-duration manifest also records the native Codex Runner integration suite's measured import and execution cost, so the existing file balancer accounts for it in both ordinary PR and release verification.
Cloud readiness runner placement
When AWS routing is enabled, Cloud image builds use paperclip-cloud-build-x64
and source verification uses paperclip-post-merge-x64. The artifact wait and
the Cloud source verified v1 and Cloud deployable v1 marker jobs run on
GitHub-hosted runners. These small jobs must not hold or wait for capacity in
the source-verification fleet. During a merge
burst, even a completed build must wait for its marker before consumers can
recognize readiness.
Runner placement does not change readiness requirements: exact-source artifacts, all source checks, and the image verification must still pass. The versioned markers and their dependency gates are unchanged.
