feat(issues): limit agent-created task trees to parent and child (#19312)
## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agents split work into tasks. A task can have a parent task. > - Today agents can nest tasks to any depth: parent, child, grandchild, and deeper. > - Deep agent-made trees are hard to follow, and an agent that works on a child task makes grandchildren by default. > - This pull request limits agent-created trees to two levels: a top-level task and its children. > - A request for a grandchild does not fail. The server puts the new task beside the requester and tells the agent. > - Board users keep full control. They can still nest to any depth. Existing deep trees stay valid. > - The pull request also records which task created each new task, so the audit trail stays complete when the parent changes. ## Linked Issues or Issue Description No public issue exists. This is the feature description. Related: #16853 (budgets that include descendant work) also reasons about task trees; this change does not alter its traversal. **Subsystem affected** Issues (tasks): create, child create and move in the issue service and routes. Agent tools, chat suggestions and creation provenance use these paths. **Problem or motivation** Agents create subtasks as deep as they want. An agent that runs on a child task gets that child as the default parent, so its follow-ups become grandchildren. The trees become deep and hard to read. The parent link is also the only record of which task created a follow-up, so that record is lost when the parent changes. **Proposed solution** Limit agent-created trees to a parent and its children. When an agent asks for a grandchild, put the new task under the requester's parent and return `parentAdjusted`. Do not reject the request. Keep board users unrestricted. Record the originating task in a new server-set `origin_issue_id` column. Keep `origin_run_id` as the originating run. **Alternatives considered** Reject grandchild requests with an error. We did not do this, because agents then fail mid-task. Add a database constraint. We did not do this, because existing deep trees must stay valid and nesting can return later. ## What Changed - Add `MAX_AGENT_TASK_HIERARCHY_DEPTH` (2) and the `IssueParentAdjustment` type in `packages/shared`. - Add `resolveNewTaskParent` and `planIssueParentChange` in `server/src/services/issues.ts`. `create`, `createChild` and `update` use the agent limit by default (`parentDepthPolicy: "flatten"`). - The issue create, `/children` and PATCH routes pass `allow_nested` for board users. For agents, the routes check authorization against the parent that the server actually writes. - The requester keeps its behavior when the server moves a task beside it: `blockParentUntilDone` blocks the requester, and the new task inherits the requester's workspace and privacy. - The server never moves a task above a low-trust boundary root that contains the requester. - These subsystems keep any depth, because they find their work by parent: watchdog reviews, monitor recovery, email-channel placement, and routines that a person configured. - An agent move of a task that has children skips only the parent change and returns `reason: "has_children"`. - Add `issues.origin_issue_id` (nullable, `on delete set null`, indexed) in migration `0434`. Only the server sets it. The `createdFrom` detail field, the `createdFromIssueId` filter and task-creation provenance read it first. - Chat prompts now let a chat agent create one task, a task with children, or separate tasks. The conversation is never a parent. - The runner `create_task` tool accepts an optional `parentTaskId`. A chat agent can create a top-level task and then put subtasks under it. The run must be able to read and change the parent. A conversation is never a parent. The depth limit still applies. Project tools map the field to `parentId` through the issue route. The protocol manifest, semantic contracts and eval fixture are regenerated. - Watchdog runs that have an active watchdog keep their requested parent on all create paths, because their access is limited to the watched subtree. - Fix a bug that the test drive found: the chat (MCP) `create_task` ignored the requested `status`, so a `backlog` task became `todo` and started to run. It now uses the same rule as the native tool. - Update `skills/paperclip`, `doc/SPEC-implementation.md`, and add the plan `doc/plans/2026-11-05-two-level-task-hierarchy.md`. ## Verification - `cd server && npx vitest run src/__tests__/agent-task-hierarchy-depth.test.ts src/__tests__/agent-task-hierarchy-depth-routes.test.ts`: 19 new tests for service and route behavior, all pass. - Related suites (64 files: issues service, thread interactions, privacy, watchdogs, provenance, runner tool authority, decisions, routines, project tools): 1208 tests pass. Two tests changed because of the intended behavior and pass now. Two `email-channels.integration` tests fail locally because the test cannot find a bundled skill file from this worktree path. This change does not touch that code. - `packages/db`: migration safety, snapshot drift and journal tests pass. - Typecheck passes for `server`, `packages/shared`, `packages/db`, `cli` and `ui` (local `ui` errors come only from generated Storybook catalog files that are absent). - Local test drive on an isolated instance with real Claude agents: 29 of 29 use cases pass, including an agent on a child task (follow-ups placed beside it, with the notice) and a chat that creates a top-level task with three subtasks. - I did not run the full `pnpm test:run` or `pnpm build` locally. CI runs them. ## Risks - Behavior change for agents: some follow-ups that were grandchildren are now siblings. The parent of the requester is woken when all its children finish, which now includes these tasks. - The runner `create_task` input contract adds one optional field, so the protocol manifest and the pack contract change. The tool output does not change: it shows the actual `parentId`, and the activity log records `parentAdjusted`. - Migration `0434` adds a nullable column, a foreign key and an index. It does not backfill rows. - `IssueCreationSource.run` is now nullable. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with tool use (shell, file edits, local test runs). ## 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 - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [ ] I will address all Greptile and reviewer comments before requesting merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(db): attribute bounded captures to execution owners (#18634)
## Thinking Path > - Paperclip manages agent work through shared server and database services. > - High query volume can spend main-thread time on SQL construction and result decoding. > - The existing bounded response capture counts rows and bytes, but it cannot name the operation that executed a query. > - Bundled callers can be missing, and measuring every parsed JSON value adds work to the diagnostic. > - This pull request carries a semantic execution owner into each measured query and bounds response sizing. > - Operators can rank query volume by owner before choosing a performance fix. ## Linked Issues or Issue Description Refs #17504, #17522, #17537, #17564. **What existing behavior does this improve?** The opt-in `PAPERCLIP_DB_RESPONSE_CAPTURE_WINDOW` diagnostic. **Subsystem affected** Database diagnostics and existing server execution boundaries. **Current behavior** The capture groups by table, operation, and builder caller. It cannot distinguish execution owners that reuse a prepared query. Bundled deployments need source maps for caller locations. The capture visits every returned value and serializes parsed JSON again to estimate its size. **Proposed behavior** Version 2 captures use fixed semantic owners for HTTP requests, delivery queues, execution phases, and budget work. They count completed calls, returned rows, errors, and completion wall time. They sample successful results 1, 17, 33, and so on, with fixed cell and string/byte limits. Complex values remain explicitly unmeasured. Semantic ownership works without source maps. **Reason and benefit** A short census can identify which operations issue the most queries or return the most rows. It preserves each query's execution owner through pooled connections, concurrent operations, and prepared-query reuse. It reduces diagnostic work without claiming per-query CPU attribution. **Breaking changes** Opt-in capture output moves from `entry.v1`/`summary.v1` to `entry.v2`/`summary.v2`. Sampled primitive byte lower bounds replace all-result byte estimates. Consumers must use the new fields and must not extrapolate them into a total. There is no database migration or application API change. ## What Changed - Added `withDatabaseOperation(owner, action)` to the DB package. The server owns semantic labels. Queries retain execution ownership in their completion closure. - Added fixed owners at existing HTTP, delivery, budget, and execution timing boundaries. Delivery work replaces the context of the producer that woke it. - Added complete call/row/error counters and completion wall durations within the existing bounded window. Durations include waits and are not CPU measurements. - Sampled and bounded primitive-value sizing. Complex and oversized values remain unmeasured. Known owners skip repeated stack extraction. - Preserved the deadline, group limit, paced output, query outcomes, and existing coverage exclusions. Updated the operator documentation. - Added real PostgreSQL owner-isolation and prepared-query tests, server scope tests, and plain bundled-runtime proof. - Moved projection-test and benchmark full-response sizing into an explicit test helper. Existing payload-size thresholds remain unchanged; these synthetic checks do not use the production sampler. ## Verification - Final-commit DB capture suites: 43 tests passed in 13.86 seconds against the actual PostgreSQL driver, including concurrent owners, prepared reuse, transaction failure, a dedicated client, sampling, and a query crossing the deadline. DB typecheck passed. - Server attribution and existing delivery/execution/budget suites: 53 tests passed. Final concurrent HTTP GET/JSON POST scope refinement: 5 tests passed. - Runtime bundle suite: 8 existing tests passed. The new no-source-map owner test passed after its fixture was corrected to use a driver thenable. An ordinary native Promise can bypass an overridden `.then`; the real PostgreSQL tests separately cover driver integration. - Observer-only experiment: three alternating pairs per case on Node 24.22.2, macOS arm64, 3,000 calls per run after warm-up. For an already-materialized synthetic JSON result, median capture CPU fell from 82.37 to 1.87 microseconds/call. For a 100-row primitive result, it fell from 8.10 to 4.40 microseconds/call. Every result retained identity and all calls were counted. The new diagnostic intentionally measures less byte data; these are observer costs, not database latency or a hosted application speedup. Disabled-case timings were below one microsecond/call and too small for a performance conclusion. - Final lifecycle regression: 28 unit tests and DB typecheck passed. Closing the last capture disables and replaces owner storage; overlapping captures retain it. - Final-commit full recursive typecheck passed in 38.38 seconds and full build passed in 40.81 seconds. The build stamp matches `83ed4ba9cebd68d48929c46f15ab32d5c0b9687b`. Focused server attribution tests also passed 5/5 before the test-helper-only migration. Full test acceptance will use the repository's parallel CI gates; the unsharded local command takes hours. - Verification failures retained: initial sandbox runs could not open local IPC/PostgreSQL listeners; permitted reruns exercised the real services. One old test expected JSON serialization and was updated to assert explicit unmeasured complex values. The first bundle fixture used the wrong promise boundary, as described above. A retained-callback regression also demonstrated that disabling and reusing the same AsyncLocalStorage instance could resurrect an old owner; replacing the instance after the last capture closes fixes that case. - The first CI run found older projection tests consuming the previous full-response fields. Those consumers now use the full-response test helper, preserving their byte thresholds. The two complete affected route suites plus helper tests passed 115/115 in 73.08 seconds. A temporary full-row query negative control then failed the unchanged 2,048-byte limit at 5,000,812 bytes and was restored; five other service suites passed 34/34 and the affected chat cases passed 3/3. All three previously failing CI shards passed on the corrected head. A local skill-list benchmark smoke check completed 255 captured queries with no in-flight queries or overflow; this was integration verification under concurrent test load, not a timing benchmark. - Two final-head runner jobs lost communication with GitHub before reporting a test result. One targeted retry of those jobs and their dependent aggregate passed. All 53 final-head checks passed, with 3 intentional skips; previously passing suites were preserved. - Hosted capture remains pending until the reviewed revision is deployed and a bounded window is explicitly configured. Reproduce the focused checks with Node 24 and the repository pnpm version: ```sh pnpm exec vitest run packages/db/src/response-capture.test.ts packages/db/src/response-capture-postgres.test.ts pnpm --dir server exec vitest run --config vitest.config.ts src/__tests__/database-operation-attribution.test.ts scripts/bundle-runtime.test.mjs pnpm -r typecheck pnpm build ``` ## Risks - Owner context is active while a valid future capture window is armed, up to 30 minutes before accounting starts. No-window and expired calls take the direct path. Diagnostics still add bounded work while enabled. - A nearest nested owner is reported. Broad `http.request` and unattributed groups remain visible; this does not identify every service callsite or SQL shape. - The existing census excludes tagged/raw explicit-execute/streaming paths and internal protocol commands. Its counts are not PostgreSQL transaction totals. - Completion wall time includes queue/database/network/scheduling waits. Concurrent durations overlap. Sampled bytes exclude complex values, large strings, and values beyond the sizing limits. - Activation is startup-only. Operators must choose the window after artifact preparation, allow rollout/warm-up time, and remove the expired setting afterward. ## Model Used OpenAI Codex, GPT-6 family, with code execution, repository inspection, and parallel agents. The exact deployment 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> |

Read only task creation provenance fields (#17604)
Narrow saved-run provenance reads to current identity, scope, and typed legacy bindings. Preserve binding precedence, current viewer checks, and complete stored runs. Real PostgreSQL and route tests pass 23 cases; legacy full-context and type-coercion regressions are caught. Exact-head required CI is green; Greptile is 5/5 with Low impact and no unresolved comments. Co-Authored-By: Paperclip <noreply@paperclip.ing> |
