DottaandPaperclip	412834a860	test: overlap long recovery and maintenance waits (#18544) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - CI verifies recovery, execution authority, and background work before changes merge. > - Diff selection saves work, but a selected file still runs its cases in sequence. > - The three longest files in a recent full master run each took over eight minutes. > - Many of these cases must observe real lease expiry or idle periods. > - This pull request gives independent cases separate fixtures so those periods can overlap. > - The benefit is a shorter test path with the same assertions and observation windows. ## Linked Issues or Issue Description Refs #18464. The latest measured successful master [Cloud readiness run](https://github.com/paperclipai/paperclip/actions/runs/41300933157) spent 581 seconds in issue recovery, 569 seconds in native restart recovery, and 512 seconds in maintenance server routes. File-level selection cannot divide those long serial files. Shortening their lease or idle windows would weaken the regressions they protect. ## What Changed - Split issue recovery into four files with separate database and worker fixtures. Keep all 18 cases. - Split native restart coverage into recovery, lease renewal, preparation, checkpoint cost, and disk-loss files. Keep all original 79 cases, including the existing container-qualified cases. The master update also retains its newly added recovery cases. - Close each native case's database clients after pending failure reports drain. The shortened file must not rely on idle timeouts to stay below PostgreSQL's connection cap. - Run the native Runner lane with two isolated fork workers. Register every new file in the lane and verify that the partition still includes every suite. - Give each maintenance case an owned database. Run at most two cases together with test-local assertion contexts. Keep both real 90-second quiet windows and all 17 cases. - Preserve serial execution when any explicit shared `PAPERCLIP_*_TEST_DATABASE_URL` is present. An admin URL that creates a separate database per fixture can run concurrently. - Refresh shard weights from the protected master run. Mark the initial split-file weights as conservative estimates until master measures them. - Anchor the attention-retention fake clock to PostgreSQL time. Its fixed clock started trailing real database timestamps after 12:00 UTC on November 1, causing an archive-deadline test to time out. Keep its deadline assertions and timeout unchanged. - Document the fixture and concurrency rules. Leave runner authorization and workflows unchanged. ## Verification - Final head `c9a4ff11b3ba81277341294c7721b34fb8705ede`: [full PR CI passed](https://github.com/paperclipai/paperclip/actions/runs/41477848686), including typecheck, build, all test shards, E2E, and the final verification gate. The rollup has 55 successful checks, one neutral review check, four expected skips, and no pending or failed checks. Greptile reviewed this exact head at 5/5 with no actionable findings. - November 2 master update: merge commit `c9a4ff11b3ba81277341294c7721b34fb8705ede` resolves the native recovery import conflict while retaining the new busy-row and remote continuity cases from master. All 38 test-runner checks and the three new busy-row cases passed locally. - Retention verification after the master update: the first local full run passed 52 cases and timed out at 15 seconds in the paged-backlog case. That case passed in isolation. The unchanged master suite passed all 53 cases (82.95 seconds), and a full PR rerun also passed all 53 (76.65 seconds). The initial timeout cause remains unproven; no timeout or assertion was weakened. - Previously verified head `fd288a8e8c88df54dcdca7b7e42366b019182782`: [full PR CI passed](https://github.com/paperclipai/paperclip/actions/runs/41312625439). There are 55 successful checks, one neutral review check, four expected skips, and no pending or failed checks. Greptile reviewed this head at 5/5 with no actionable findings. - Issue recovery: 18/18 passed before and after the split on the same local machine and PostgreSQL fixture path. Wall time changed from **630.6 seconds to 319.7 seconds** (49% less). All case titles match. - Maintenance also passed all 17 cases on AWS: structured file cost dropped from **511.8 to 282.6 seconds** across the linked master run and the first PR run. These are different CI runs, so the matched local comparison below is the stronger isolated measurement. - Maintenance: 17/17 passed before and after with the restored pinned dependencies. Wall time changed from **488.1 seconds to 317.2 seconds** (35% less). All 120 assertion lines remain. Both real 90-second windows also passed a final targeted run. - Native restart: 71 passed and eight existing container-only skips before and after the split. Wall time changed from **632.1 seconds to 346.8 seconds** (45% less). All 79 cases and 254 assertion lines remain. - `pnpm -r typecheck`: passed. - `pnpm build`: passed. - Extra TypeScript checking of the moved recovery and maintenance tests passed. The standard server config excludes `src/__tests__`. A separate check of attention-retention fixtures reports existing type errors; the unchanged baseline has identical diagnostics, with none introduced by the clock fix. - `node --test scripts/__tests__/run-vitest-stable-shard.test.mjs scripts/ci/test-selection*.test.mjs`: 61 passed. - `pnpm test:run`: stopped in the second chat partition: 335 passed and four failed (two GitHub retry-state assertions and two Teams timeouts), after 339 passed in the first partition. These chat tests are unchanged. All four pass in a focused run (19.1 seconds). The full-suite ordering/load cause remains unproven. All three CI chat jobs passed. The previously failing cases passed there in 1.3, 1.3, 2.4, and 2.2 seconds; see [the chat job log](https://github.com/paperclipai/paperclip/actions/runs/41309691650/job/124857580714). The attention-retention timeout repeated in CI and in an isolated local run. Its fake clock was fixed at November 1 noon, which had fallen behind real PostgreSQL timestamps. Anchoring it to the database clock passes all 53 cases; the failed case now takes 425 ms. - The native CI lane passed all 162 runnable cases with eight existing skips after client cleanup: **650.7 seconds on the earlier master run to 391.0 seconds on this PR**. - CI found native connection exhaustion after the long waits moved out of the main file. The same failure reproduced locally at a 100-connection cap. Per-case client cleanup fixes the shortened file at that cap, and all five native files now pass together at that cap (71 passed, eight existing skips). - Early attempts exposed a missed fixture reference and a missed reporting setup hook during extraction; both were restored. The first CI policy run also required moving the new native fixture under test helpers; that boundary check now passes locally. A separate auxiliary command picked up the host pnpm version and removed dependencies. The original maintenance baseline reproduced the same missing-package failures, so that failed attempt is excluded from timing comparisons. A later unchanged-baseline run passed all 17 cases. The pinned install was restored before the passing maintenance run. The audit also covered heartbeat process recovery, deferred receipts, chat, workspace recovery, attention, and connection management. Their shared fake clocks/provider mocks or existing partitioning need different changes. The 16,400-row attention case and the large checkpoint stream remain intact because their size protects real limits. ## Risks - Two isolated processes use more memory and database connections than one. Concurrency is capped at two. Shared database overrides force serial execution. - Moving setup into helpers can change test lifecycle order. The split suites keep the same case assertions and use independent process state; focused runs and the full CI suite check the move. - Split-file weights are estimates based on case timings from the linked run plus repeated setup cost. The next protected-master refresh replaces them. Weights never permit tests to be skipped. - Local timing varies with host load. CI measurements after merge are needed to establish the overall PR wall-time improvement. ## Model Used OpenAI Codex, GPT-6, with reasoning, repository inspection, tool use, and code execution.

DottaandPaperclip	e40de0c9e8	perf(ci): refresh test weights and narrow graph dependencies (#18464) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Contributors need fast, reliable CI feedback. > - Diff-aware CI selects test files and partitions them into runner jobs. > - Stale cost estimates put several slow suites on the same runner. Broad imports also couple small tests to large modules. > - This PR refreshes test costs, runs independent graph discovery in parallel, and narrows three dependency boundaries. > - Selection safeguards and CODEOWNER-only AWS routing stay in force. ## Linked Issues or Issue Description Refs #18398. This follows the audit of [PR #18427's verification run](https://github.com/paperclipai/paperclip/actions/runs/41169978784). The audit found 403 selected general-server files without timing weights. Three suites measured at 232s, 122s and 116s shared one shard because each received a roughly 2s fallback weight. Local graph discovery across four projects took 43.7s serially and 21.7s with two workers. A reverse-order repeat took 37.7s serially and 22.6s with two workers. Both comparisons produced identical selection results. This is a local measurement, not a claim about production CI speed. ## What Changed - Refresh general-server costs for 1,285 of 1,309 current files and serialized costs for all 163 files from two successful protected-master Cloud readiness runs. Retain prior costs for unmeasured files, including dedicated chat and native-runner suites. - Record passing server file costs, including collection, setup and environment preparation. A weekly hosted workflow validates trusted source runs and opens a timing-only PR. It tests shard coverage, pauses while a refresh PR is open, and never merges automatically. - Discover at most two project graphs concurrently in isolated, heap-limited Node processes. Cache repeated inventory reads within one selection. Worker errors and timeouts retain the full task plan. - Fetch only the merge commit and parents for the selector. A real shallow-clone regression proves the complete diff still includes more than 300 files, renames and deletions. - Share the identical log viewer and run details between both AgentDetail pages. The viewer test imports the shared implementation and runs each of its 13 distinct cases once. - Extract the pure API error class while preserving the API client's public exports. Import delivery work signals through their existing narrow DB export. ## Verification - PASS: `pnpm -r typecheck` and `pnpm build`. - PASS: 284 CI selection, timing, shallow-diff, sharding and routing tests. - PASS: 74 further cache, routing and graph-proof tests. - PASS: 94 targeted UI assertions across the viewer, run invocation, API errors/client and progress helpers. All 76 assertions in the 12 server suites made independently selectable also pass. - PASS: `pnpm check:token-gates`, module-boundary checks, YAML parsing and `git diff --check`. - PASS: [Full PR CI and required `ci / verify` aggregate](https://github.com/paperclipai/paperclip/actions/runs/41206683345), including all 12 general-server shards, all nine serialized shards, workspace groups, chat suites, Runner lanes and build checks. - PASS: [GitHub hosted real-workspace selector and cache/routing qualification](https://github.com/paperclipai/paperclip/actions/runs/41206683205). - PASS: Both Greptile and Paperclip reviews are 5/5 with no actionable findings or inline comments on `7dc65c51b8`. The PR has no merge conflicts. - PASS: The production refresh parser accepted all 107 structured file-cost records from a real successful server CI job, including setup/loading cost. - Local `pnpm test:run` completed all six chat shards successfully. The duplicate monolithic local run was stopped after the complete remote suite passed; it was not completed locally. The focused log-viewer command improved from 18.84s (26 duplicate variant cases) to 8.49s (all 13 distinct behavior cases). The dependency audit confirms 12 server files and the API-error test no longer need conservative always-run retention. Repartitioning the audited PR with the new costs changes the slowest shard from 810s to 591s of summed historical test execution (1,124 of 1,142 files measured). This is a workload simulation, not measured new CI wall time. ## Risks - Two graph processes use more peak memory. Each has a 2 GiB heap limit and a three-minute timeout. Any failure preserves the original task plan. Real workspace qualification runs in GitHub CI. - Historical logs contain test/hook costs only. New reporter records add loading/setup costs after merge. The manifests identify measurement coverage and source runs. These weights change placement, never permission to skip tests. - Runner load adds timing noise. The refresh uses medians and requires at least 90% measurement coverage in each lane. - GitHub may require approval to run checks on a PR created with `GITHUB_TOKEN`. Refreshes remain reviewable and do not merge themselves. - The shared viewer is a mechanical extraction. Both pages retain their existing exports, and the behavior assertions remain covered. AWS runner authorization is unchanged. ## Model Used OpenAI Codex, GPT-6, with repository inspection, reasoning, code execution and GitHub tools. The exact deployment ID and context-window size were not exposed in this session. ## 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 references) - [x] My branch name describes the change and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass (focused checks and six chat shards; complete suite passed in CI as detailed above) - [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>	2026-10-31 11:05:12 -05:00
DottaandPaperclip	9077748894	Remove the Pipelines experiment and preserve its data (#16834) ... ## Thinking Path > - Paperclip manages AI agents and their work. > - Pipelines was an unused experiment with its own UI, API, CLI, and automation. > - Keeping it leaves unsupported product surfaces and extra task-detail queries. > - Removing the experiment must preserve data that users already saved. > - This pull request removes the feature and keeps its database schema and migration history. > - Cases and Routines remain available as separate features. ## Linked Issues or Issue Description **What existing behavior does this improve?** Remove the unused Pipelines experiment across the application. **Current behavior** The experiment includes pipeline boards, stage settings, case automation, review queues, learnings, permissions, and CLI commands. Task detail also queries pipeline links. **Proposed behavior** Remove all these product surfaces and their implementation. Preserve existing tables, records, and documents. Ignore the retired boolean in older managed configurations so upgrades still start. **Breaking changes** Pipeline URLs, API endpoints, CLI commands, and `pipelines:write` are removed. Task detail no longer includes the old `linkedCases` field. The independent Cases API remains available. No database migration or cleanup is included. Related feature work: #7907, #9110, #10905, #11375, #13004, #14671, #16133. Related issues: #9663, #10310, #10312. This removal supersedes the feature; it does not implement those pending enhancements or delete their saved data. ## What Changed - Remove Pipeline UI pages, navigation, gates, clients, query keys, helpers, and unused design tokens. - Remove Pipeline REST routes, services, automation dispatch, task-detail queries, and OpenAPI discovery. - Remove the CLI commands, shared contracts, experimental flag, catalog entry, and permission defaults. - Remove feature-specific tests, tutorials, smoke scripts, maps, and Storybook examples. - Preserve database schema, migration history, and the reserved document key used by old records. - Keep Cases routes independent and cover obsolete stored and managed settings. ## Verification - Passed: `pnpm build` and `pnpm -r typecheck`. - Passed: targeted settings, managed configuration, sidebar, settings UI, routing, and feature-catalog tests. A first sidebar run caught a shared Workspaces icon import; the import was restored and the sidebar rerun passed. - Passed: 40 tests covering Cases routes, OpenAPI discovery, retained Pipeline table constraints, and schema snapshot drift. - Passed: token gates, map validation, generated API metadata check, Storybook catalog validation, and 28 map/catalog tests. - Passed: isolated local browser verification of navigation and Experimental settings with Pipelines absent; Cases and Routines still open normally. Live GET/POST requests to retired Pipeline endpoints return 404, and the retired setting is absent. CLI help has no Pipeline commands. - Passed: 22 access-service and agent-default-grant tests after restoring unrelated permission assertions flagged in review. - Local full run: `pnpm test:run` reported one failure in the unchanged workspace-runtime port-allocation test. That test passed in an isolated rerun. The long local run was stopped after full CI passed; it is not reported as a complete local pass. - Passed: all 56 checks on `def9181f3a4491d95fca1d38e9739f5b821aae3e` (2 conditional checks skipped), including build, typecheck, test shards, and browser suites. Eleven interrupted CI jobs reported “The operation was canceled”; their one-time retry passed. [CI run](https://github.com/paperclipai/paperclip/actions/runs/39255211006). - Greptile: 5/5 on the final commit, with the only review finding fixed and resolved. - Sandbox socket restrictions affected the first build/API test attempts. The same commands ran with local sockets available. ## Risks - Existing Pipeline clients must stop using the removed endpoints and commands. - Existing data remains in the database and backups, but the removed UI no longer displays it. - Historical boolean `enablePipelines` values are ignored. They cannot restore the feature. - Cases and Routines must retain their separate behavior. Targeted route tests cover this boundary. ## Model Used OpenAI Codex, GPT-6, with repository inspection, editing, shell execution, and browser verification. The exact deployed model ID and context-window size are not exposed in this session. ## 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>	2026-10-19 08:09:46 -05:00
Devin FoleyandPaperclip	8df3ee2cf5	ci: rebalance serialized tests with current suite durations (#13328) ... ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Cloud deployments wait for verified source commits. > - Verification splits serialized server tests across independent runners. > - The shard duration estimates came from August and no longer match current tests. > - Stale estimates put much more work on one runner than the others. > - This PR refreshes the estimates from a complete successful run to balance the existing runners. ## Linked Issues or Issue Description **What existing behavior does this improve?** The time spent waiting for the slowest serialized server-test shard in PR and release verification. **Current behavior** In [Cloud readiness run 34705914878](https://github.com/paperclipai/paperclip/actions/runs/34705914878), the five serialized shards spent 479, 371, 322, 390, and 365 seconds running tests. The recovery suite had a 55-second estimate but now takes about 156 seconds including process overhead. **Proposed behavior** Use fresh per-suite measurements with the existing deterministic duration balancer. Applying the same measured costs to the new assignment gives 385, 385, 386, 385, and 385 seconds. This predicts about 93 seconds less waiting for the slowest shard, before runner/setup overhead. Live CI will confirm the result. **Reason and benefit** Use the existing runners more evenly. No extra runner, test parallelism, cache, timeout, or routing change is needed. **Breaking changes** Suite-to-shard assignments change. The full suite set, assertions, and per-suite process isolation stay the same. **Additional context** Searched related CI and shard PRs. This updates the existing duration manifest, without duplicating a pending sharding implementation. ## What Changed - Refresh all 145 serialized suite weights from the same successful release verification run. - Record source job IDs and the measurement method in the manifest. Durations include process startup, imports, collection, tests, and shutdown. ## Verification - Passed all 30 shard and release-workflow tests: `node --test scripts/__tests__/run-vitest-stable-shard.test.mjs scripts/__tests__/release-verify-workflow.test.mjs`. - Confirmed every measured suite appears exactly once across all five source logs. - Compared old and new assignments using the same measured weights. The maximum fell from 478862ms to 385551ms. - In [PR CI run 34710696242](https://github.com/paperclipai/paperclip/actions/runs/34710696242), all five serialized jobs passed in 7m05s–7m27s including setup. The measured assignment is now balanced in a live run. - The same run passed full typecheck, all grouped tests, native verification, build, release dry run, and browser checks. Local full-suite verification on this base was limited by disk exhaustion; local typecheck and targeted shard tests passed. - Latest-head Greptile is 5/5 with no open findings. Every current-head CI check must be green or intentionally skipped before merge. ## Risks - Individual durations vary with load and future test changes. These estimates affect assignment only; missing or renamed suites receive the existing median weight. - Both PR and release verification read this manifest, so both receive the new assignments. Each suite still runs in its own serialized Vitest process. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository tools, and code execution. The exact serving model ID and context window are not exposed by this environment. ## 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>	2026-09-12 11:36:20 -07:00
3 people	49217aadf0	refactor: balance serialized server shards by recorded suite duration (#11528) ... <!-- Write all pull request text in Simplified Technical English (ASD-STE100). --> ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The PR verify workflow gates every pull request; its wall-clock time sets the feedback loop for all contributors > - In a recent successful PR run (actions run 32012408876), the slowest check was "Verify serialized server suites (1/5)" at 337s, while its four sibling shards finished in 212-238s > - The serialized lane assigns suites to shards round-robin over an alphabetical list, so the heavy heartbeat and issues suites cluster on one runner > - The general-server lane already solves this with a duration-aware LPT partition backed by a recorded manifest > - This pull request reuses that partitioner for the serialized lane with a fresh per-suite duration manifest > - The benefit is a balanced serialized matrix: the measured 968s suite total levels to about 194s per shard, which removes about 80-100s from the run's slowest check ## Linked Issues or Issue Description **What existing behavior does this improve?** The `Verify serialized server suites` shard matrix in `.github/workflows/pr.yml` distributes route/authz test suites across five runners. **Subsystem affected** CI / test infrastructure (`scripts/run-vitest-stable.mjs`). **Current behavior** `selectSerializedSuites` assigns suites round-robin (`index % shardCount`) over the alphabetically sorted file list. The heavy suites cluster on shard 1/5. In actions run 32012408876, shard 1/5 spent 291s in its test step while the other shards spent 170-201s, which made that job (337s total) the slowest check of the whole PR run. **Proposed behavior** Partition the serialized suites with the same duration-aware LPT algorithm the general-server lane already uses (`scripts/general-server-shard.mjs`), backed by a new per-suite duration manifest. All five shards then carry about 194s of measured test time. **Reason and benefit** The slowest check bounds PR feedback time. Balancing the serialized matrix removes about 80-100s from that bound without adding runners. **Breaking changes** None. The partition remains deterministic, complete, and non-overlapping; suites missing from the manifest get the median weight. ## What Changed - Added `scripts/serialized-shard-durations.json`: per-suite wall-clock durations (ms) for all 134 serialized suites, sampled from actions run 32012408876 by diffing consecutive per-suite label timestamps in the shard logs (captures vitest spawn overhead, not just reported test time) - `scripts/run-vitest-stable.mjs`: `selectSerializedSuites` now uses the existing LPT partitioner (`selectGeneralServerShard`) with the new manifest instead of round-robin - `scripts/__tests__/run-vitest-stable-shard.test.mjs`: added a manifest-freshness test and a shard-balance test for the serialized lane, mirroring the general-server ones - `.github/workflows/pr.yml`: updated the serialized matrix comment with the new measurement and mechanism ## Verification - `node --test ./scripts/__tests__/run-vitest-stable-shard.test.mjs` passes (13 tests), including the existing test that the serialized shards form a complete, non-overlapping partition - Dry-run of all five shards shows estimated totals of 194/194/194/194/193s (round-robin was 276/175/160/172/187s): `node scripts/run-vitest-stable.mjs --mode serialized --shard-index N --shard-count 5 --dry-run` - The `Verify serialized server suites` jobs on this PR run the real partition end to end ## Risks - Low risk. Selection logic only; the vitest invocation per suite is unchanged - A stale manifest degrades gracefully: unknown suites get the median weight, and a dedicated test fails if fewer than half the current suites have recorded durations ## Model Used - Claude (Anthropic), model ID `claude-fable-5`, agentic coding session with tool use (Claude Code / Claude Agent SDK); no extended-thinking mode ## 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 Related prior work: #10923 (split serialized tests into five shards), #10925 (general-server duration manifest), #11156 (workspaces-a native shards).
