DottaandPaperclip	1c9ca5829f	perf(ci): overlap Runner workloads and cache debug workspace builds (#18794) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Required CI checks protect its server and Runner contracts. > - Recent full runs waited on general server files and the final Runner lane. > - That Runner lane ran package tests before native server tests. > - PR jobs also rebuilt unchanged debug workspace binaries. > - This pull request overlaps those workloads and reuses exact trusted build inputs. > - The benefit is a shorter critical path with the same test coverage and AWS authorization. ## Linked Issues or Issue Description Refs #18544, #18773, #18774, #18798, #18799. **What existing behavior does this improve?** The wall time of required PR tests and the precision of affected-test selection. **Current behavior** General server and native files use two workers. The second Runner Vitest lane runs its package shard and then the native server group. Each Runner job compiles debug workspace units again. A Vite raw import also retains its consumer for unrelated source edits. **Proposed behavior** Use three isolated workers for general server files and four for native files. Reuse the two Runner slots for a complete package suite and a complete native server suite. Restore all debug binaries only on an exact input key. Record raw imports as explicit file inputs. ## What Changed - Separate the Runner package and native server workloads without adding CI jobs. Preserve the old command arguments for master-pinned workflows, local commands, and other shard counts. - Increase file workers while retaining fork isolation, serial cases, and the shared-database guard. - Add an exact debug workspace cache. Derive binary targets from Cargo. Include source, fixtures, generated inputs, manifests, compiler identity, flags, Cargo configuration, and checkout path in its key. Discard incomplete restores. Only verified master pushes can save it. - Keep older PR checkouts working when they lack the new cache helper. - Track Vite `?raw` imports as repository file inputs. Keep unknown loaders, untracked files, and opaque effects conservative. - Add cache and coverage guards and document the behavior. AWS runner authorization is unchanged. - Keep paired test benchmarking available when install hooks correctly disable materialized dependency reuse. The old benchmark asserted a cache hit in that safe fallback. - Wait for active dispatch work to finish before asserting idle reads. Analyze the two 16,400-row database fixtures before their queries so they have current planner statistics. Suppress only PostgreSQL notices inside the cleanup transaction to avoid logging every cascaded table; warnings/errors remain visible. Row counts, real queries, assertions, database reset, and timeouts remain unchanged. ## Verification - 196 affected CI tests passed, including routing, coverage, selection failure fallbacks, shared-database serialization, and existing/new cache guards. Final worker/cache adjustments also passed their focused checks. - `pnpm build` and `pnpm -r typecheck` passed locally. Full test coverage is being verified by the Linux CI profile; `pnpm test:run` was not repeated as a full serial local run. The paired CI benchmark passed. Both paired benchmarks passed, and full CI passed again after integrating newer master commits. The external Paperclip Review app is the only pending status. - Actual debug artifacts remained fresh after simulating checkout timestamps: Cargo completed in 0.82 seconds; the content key was unchanged. This is local reuse evidence, not a measured GitHub cache transfer. - Same real UI inventory for a retention-test-only change: 861 files; retained selection fell from 413 to 401. All 12 omitted files are raw-input consumers; edits to their inputs remain covered by regression tests. - The first local worker comparison is invalid. Development dependency links disappeared during its second run. The two-worker baseline also had two macOS path assertions in company-skills. Neither result is counted as a successful speedup. Dependencies were restored. A local repeat was interrupted before producing results. The completed Linux comparison below supplies the valid paired evidence. - [Paired Linux benchmark](https://github.com/paperclipai/paperclip/actions/runs/41671244016): baseline and candidate ran the same 113 general-server files and 1,777 cases on one host. Wall time fell from 381.29s to 346.89s (9.0%). Both exited successfully and file/case inventories matched exactly. The fixture command took 31.77s versus 28.65s. This is one sequential pair, excluding setup, queueing and the full CI critical path. - [Repeat paired Linux benchmark](https://github.com/paperclipai/paperclip/actions/runs/41675496862): the same 113 files and 1,974 cases took 485.06s in the baseline versus 368.54s in the candidate (24.0%). File and case inventories again matched exactly. The baseline includes newer master changes than the first pair, so these are two independent comparisons, not repeated timings of an identical tree. - Initial full AWS profile: package suite passed 4,891 tests (289 files, one skipped); native suite passed 172 tests (9 files, 12 pre-existing platform/feature skips). Native execution took 239.06 seconds; the older sample ran 165 native tests in 391.29 seconds. The package lane now takes 11m01 including setup and debug compilation. This is an indicative cross-run comparison, not a paired full-CI speedup claim. - The initial run failed two UI fixtures, one serialized inbox settlement assertion, and one dispatch idle assertion. The two UI failures reproduced locally. The fixes preserve authorization, admission, and zero-idle-read assertions. All four affected files passed locally: 48/48 tests. Token gates passed. All four also passed in the next AWS profile. That profile passed every other workload but timed out the 16,400-row keyed attention fixture at its existing 180s limit; this is accounted for by the explicit fixture-statistics change. Local focused comparisons pass both large cases before and after; their roughly 33s test execution is unchanged locally, so this is not claimed as an additional speed gain. A full local file run passed both large cases (7.57s / 18.05s) but hit the unchanged 30s teardown deadline on its first test while emitting thousands of cascade notices. Cleanup now suppresses those notices within its transaction; the complete file then passed 34/34 in 107.72s. The latest-head AWS run passed the previously failing shard: the keyed bulk case took 40.25s (previously exceeded 180s), the keyless case took 8.02s, and the complete attention file took 89.61s. The 16,400-row fixtures and original timeouts remain intact. - [Full CI profile before master integration](https://github.com/paperclipai/paperclip/actions/runs/41675497699) passed on commit `5858956d4ac2c99c911ad2447b63e1f8fc84e31e`, including all tests, build, typecheck and final verification. Greptile reviewed that exact commit at 5/5; the only actionable review thread is resolved. The separate Paperclip Review app is still queued. - [Final merged-head CI](https://github.com/paperclipai/paperclip/actions/runs/41678956312) passed on `499aa206a6e03bf8f3249692ea731367a000591d`: 48 successful jobs and one intentionally skipped file-selection job. Backup checkpoint qualification and legacy security status passed. Greptile reviewed this exact commit at 5/5. The PR is conflict-free; only the separate Paperclip Review app remains queued. - Integrated current master after #18798 and #18799 merged the inbox and UI fixture fixes separately. Preserved master's inbox settlement fix and verified its entire file (6/6 tests). Those three files are no longer part of this PR's diff. Removed the temporary `profile-ci` label after both successful benchmark pairs; the normal planner still schedules every job because the CI configuration changes are global inputs. - Second AWS profile: native tests took 229.97s with the same 172 passes / 12 skips; package tests took 427.44s with 4,891 passes / 10 skips. The complete package job took 10m44, including setup and 79s debug compilation. - The PR uses the trusted workflow from master. Candidate worker/layout code runs now; workflow-level debug restores begin after merge and the first successful master cache writer. ## Risks - Extra workers can expose load-sensitive tests. The final full CI profile passed, but one run is not a long-term flake-rate measurement. - The cache is an optimization only. Misses rebuild, and test commands still execute. A new Cargo workspace member requires a cache-contract review. - Compiler alternatives remain experiments. Required TypeScript checks are unchanged. Typechecker experiment: three sequential checks per tool on identical built projects, with TypeScript 7.0.2, Bun 1.4.4, and tsrs 0.20.1-ts7.1.0-beta. Median seconds (TypeScript / Bun / tsrs): shared 0.429 / 0.083 / 0.157; UI 2.554 / 0.390 / 0.740; server 9.949 / 1.194 / 1.782. TypeScript and Bun passed all three projects. All tools caught the same four deliberate assignment, property, nullability, and generic-constraint errors. tsrs reported one additional server TS2345 diagnostic in the run-dispatch adapter, so it did not pass the project comparison. These local compiler times exclude generation and build steps; they are not full CI savings. ## Model Used OpenAI GPT-6 Codex. Tool use and code execution assisted this change.

DottaandPaperclip	7ec6fd0972	perf(ci): remove repeated test setup and fixture work (#16429) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - CI must check changes without making contributors wait for repeated setup. > - A complete CI profile showed 158 serialized Vitest launches and repeated dependency installs. > - A large fixture also transferred 40,000 files to prove two different size boundaries. > - This PR removes repeated controller, install, build, transfer, and wait work. > - It keeps isolated test processes and all useful regression boundaries. > - Paired command benchmarks check speed and test inventories before we claim a benefit. ## Linked Issues or Issue Description Refs #16423 for the complete CI profiling data path. No duplicate optimization PR was found. **Current behavior** Each serialized file starts a new Vitest controller. Each CI lane restores the pnpm store and installs dependencies. Large Git scanning and staging share one 40,000-file fixture. A readiness regression waits over a minute for the default database idle deadline. **Proposed behavior** Use one controller per serialized shard, with a fresh fork for each file. Restore exact installed dependencies and certified shared/SDK build outputs when inputs match. Keep the normal install and build paths on a miss. Separate the 32 MiB Git scan proof from staging above command argument limits. Cross a real database idle deadline with a one-second fixture setting. **Reason and benefit** The paired Linux CI benchmark reduced the complete 566-case serialized shard from 303.43s to 246.96s (18.6%). The Git/database fixture command fell from 156.54s to 33.78s (78.4%). Exact dependency/build restoration reduced setup from 56s to 19s (66.1%). These are measured command/setup times. They do not establish a controlled reduction in the full workflow's queue-to-completion time. **Breaking changes** None to application behavior. Tests still run in full. Test results are not cached. Cache misses preserve the existing lockfile resolution fallback. ## What Changed - Batch serialized files into one isolated, single-worker Vitest invocation per shard. Give each worker its own home, config and instance ID. - Add a real two-order isolation check for processes, environment, globals, timers and filesystem state. - Add exact dependency keys for all manifests, lockfile, workspace settings, patches, installer, runtime, platform, libc, pnpm, store and checkout path. Cache only installed package directories, not source fixtures. - Add a separate content key for the shared/SDK dependency graph. Retain the existing source/output fingerprint verifier and rebuild path. Only an exact canonical master push can populate normal caches. Stale lockfile fallback runs cannot publish entries. - Keep four real Git filename lanes above 32 MiB. Use a separate 4,000-file staging/deletion case above 2 MiB. Check every staged file, unusual names, cleanup and bounded commands. - Configure a real one-second PostgreSQL idle timeout in the readiness fixture. Assert that the backend connection changes and that another connection can write the parent row. - Add an opt-in, unprivileged Linux benchmark under `profile-ci`. It compares the tested merge tree with its actual first parent on one runner. It also removes installed outputs and qualifies a real cache restore using temporary PR-scoped entries. ## Verification - Local Node 24.19.0: unchanged serialized shard 255.69s; candidate 231.44s; all 566 cases pass in both. - Local fixture command: unchanged 189.13s; candidate 43.39s. Candidate scan 18.58s, staging 13.41s, database case 2.80s. All three candidate cases pass. - Negative control: moving readiness back inside the real parent-lock transaction fails the shortened regression at the parent-write assertion. The production source was restored and is absent from the diff. - Worker isolation check passes in both file orders. - 565 CI policy, partition and workflow regression checks pass with local HTTP/IPC access enabled. The first sandboxed attempt was denied listen access; it was not a code failure. - `actionlint` passes for the three changed workflows. - [All 48 main CI jobs passed](https://github.com/paperclipai/paperclip/actions/runs/38745643045) on head `5bec2edb2b194e74352ca697f3fd1d0ac03ce967`, including full typecheck, tests, build, browser E2E and release checks. All 158 serialized files and 3,250 cases passed through 9 controller invocations. Full typecheck/test/build were verified in CI; they were not all repeated locally. - [Paired Linux benchmark passed](https://github.com/paperclipai/paperclip/actions/runs/38745643127) on Node 24.21.0. Its baseline is `57fa6b358de62922cfa9a67766b2a227c434fcdf`; its candidate merge tree is `f68f1b32966090f11647502e31852130c20237cf`. The artifact contains results, exact case inventories, setup times and raw logs. Serialized case identities match exactly. All three fixture contracts execute in both variants. | Measured work | Baseline | Candidate | Reduction | |---|---:|---:|---:| | Complete serialized shard, 566 cases | 303.43s | 246.96s | 18.6% | | Git/database fixture command | 156.54s | 33.78s | 78.4% | | Dependency/build setup, cold vs exact hit | 56s | 19s | 66.1% | - [Honeycomb profile export succeeded on its second attempt](https://github.com/paperclipai/paperclip/actions/runs/38747237615/attempts/2). The first attempt failed on GitHub HTTP 503 while downloading an artifact, before export. Only the export was retried; tests were not repeated. The temporary PR-scoped qualification caches were removed after validation, reclaiming 3.34 GB. Timing artifacts remain available. - Greptile is 5/5 on the current head, with no unresolved review threads. Its P1 checkout-prefix finding was fixed in `5bec2edb2`; the corrected reporter paths and paired comparison passed. Earlier runs were superseded while this was fixed. A copy-batching experiment did not speed up the Git fixture and was replaced by the two-boundary fixture split. ## Risks - A persistent controller retains transform state longer. The local shard's maximum RSS rose from about 1.52 GB to 1.99 GB. Full CI must confirm all shards fit the runner budget. - Materialized caches are larger than metadata caches. The Linux benchmark measured real archive transfer and validation after removing installed outputs. Its hit took 19s versus 56s cold. Normal PR lanes cannot publish cache entries. Exact misses run installation. Canonical cache warming requires a frozen-lockfile install; the existing stale-lockfile fallback remains uncached. - The PR uses the trusted reusable workflow from master. The paired benchmark directly exercises the candidate dependency action; normal workflow adoption still requires this PR to merge. This PR does not change the trust references. The completed main workflow took 11m02 including queue time. No controlled full-workflow latency improvement is claimed before this workflow adopts the cache change. - Only deterministic dependency/build outputs are reused. Broad dependency-based test omission and caching successful test results are deliberately excluded from this change. - The real Runner lease minimum and cold-admission waits remain. They protect protocol boundaries and were not shortened by weakening production limits. ## Model Used OpenAI GPT-6 through Codex, with reasoning, shell execution and code tools. The runtime does not expose a more specific deployment ID or context-window size. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>	2026-10-15 09:23:47 -05:00
