## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Lifecycle plugins must refresh runtime preparation when tool definitions change. > - Standing assignments alone do not cover catalogs, profile entries, or policies. > - New journal hooks must preserve the order used by setup finalization. > - This pull request adds tool-definition invalidation and its required writer guards. > - It leaves credentials and provider access changes for the next independent capability. ## Linked Issues or Issue Description **What happened?** Catalog, profile-entry, policy, gateway, and connection-configuration changes do not request agent runtime synchronization. A new profile-entry trigger also exposes a deletion/finalization deadlock if the child row is changed before its parent is locked. **Expected behavior** Committed tool-definition changes advance runtime revisions without polling. Bookkeeping does not. Entry changes and profile replacement use a consistent parent/reference lock order and commit atomically. **Steps to reproduce** 1. Change a catalog descriptor, profile entry, policy, or connection configuration. 2. Expect committed runtime events for the affected agents. 3. Run profile-entry deletion concurrently with setup finalization while both wait for an agent row. 4. Expect both operations to complete without PostgreSQL deadlock 40P01. **Additional context** Extracted from #16503. Catalog publication #16602 and standing assignments #16603 are merged. This PR is rebased onto master and is the active review. It addresses the original Apex profile-entry deletion finding. Credential/access hooks #16605 remain a draft without review requests. ## What Changed - Add migration 0355 for application/connection configuration, catalog, profile-entry, policy, and MCP gateway invalidation. - Preserve transaction coalescing and ignore health bookkeeping and trust-rule usage counters. - Keep credential-only fields outside this migration's coverage. - Preserve merged recipient scoping for bindings and installations. Profile-entry edits resolve old/new standing profile bindings. Policy edits resolve old/new agent selectors with their intersection/list semantics. - Lock old and new profile-entry references before parent profiles and child mutations. Recheck the reference set under the parent lock, retry changed snapshots up to three times, and merge unspecified fields from the locked profile. - Make entry add/edit/delete and profile replacement transactional, including validation and profile reads on the reserved connection. - Lock policy rows in ID order and change priorities in one statement so scoped agent locks are ordered across the full set. - Lock the managed profile before connection removal deletes its entries in the same transaction. - Update assignment tests whose old absence assertions are superseded by expanded configuration coverage. - Document the supported capability and the remaining credential/access boundary. ## Verification - Final head: `809fcb11794bfb12c545af0a2f96ab9bc2b570a2`. It is rebased onto master with merged #16623. GitHub reports no merge conflicts. [CI run 39293925136](https://github.com/paperclipai/paperclip/actions/runs/39293925136) has 55 successful checks and two optional Storybook skips. - Standard Greptile returned an independent 5/5. The final Apex review returned 5/5 on this exact head at 17:47 UTC on 2026-10-19. Its summary explicitly clears this PR for merge independently of draft #16605. The security scan passed. All review threads are resolved. - Two real-PostgreSQL negative controls reproduce `40P01` without the old-reference guard or the concurrent-snapshot check. Both regression tests pass with the final correction. Server typecheck, migration safety and numbering, five-snapshot retention, journal history, feature maps, and diff checks pass. The actual PR diff was scanned for secrets and personal data before push. - The final 15-suite local run passed 821/822 tests. The one failure was in the unchanged runtime-delivery test: a startup callback changed its global callback count during an independent transaction. The test-only correction is isolated in #16871. That PR passes all 17 runtime-hook tests, server types, hosted CI, and standard Greptile 5/5. Its notification-disabled control fails at the independent event-delivery assertion. No changes from #16871 are included here; this feature head passes hosted CI independently. - Earlier affected-suite runs passed 814 tests after rebase and 820 tests after recipient and whitespace corrections. Four affected suites passed 514 tests before the second reference-contention regression was added. Single-connection tests cover entry add, edit, delete, and replacement. Validation and profile reads use the reserved transaction connection. - Review fixes have negative controls: the old code hangs with a one-connection pool; parent-lock omissions deadlock entry deletion or app removal against setup finalization; per-row policy reorder deadlocks under contention; unscoped triggers journal unrelated peers; default SQL trimming misses JavaScript whitespace. Corrected cases pass. Selector tests cover all 25 ECMAScript whitespace characters. Recipient tests cover repeated edits, old/new targets, ignored bindings, rollback, coalescing, and company scope. The definition suite now has 28 cases. - Earlier standard scores that depended on #16605 were not accepted as independent clearance. The first Apex review returned 4/5 for replacement versus application deletion. The final correction locks old and new references, checks the reference set again under the parent lock, and retries before any mutation. The final independent reviews clear that correction. - Preserve prior failures for acceptance: draft run 38975432017 had failures whose causes were not re-investigated. Run 38990400765 exposed the unrelated durable-resume watchdog race, fixed in merged #16623. In run 39287657148, two jobs reported cancellation without a failed-test summary; the cause remains unknown. Both passed on retry without source changes. Initial local fixtures and SQL bindings also needed correction: an internal helper name was replaced with public `archiveConnection`, unchanged priorities were changed to exercise reorder, a driver timestamp was bound as ISO text, and a superseded company-fanout assertion was updated. These recovered checks do not establish a cause for the unexplained CI failures. - Local checks target the affected services and real database boundaries. A full local build and repository-wide test run were not performed. Hosted CI supplies the broader checks. Provider responses in tests are controlled; live provider behavior was not qualified. ## Risks Migration 0355 adds statement triggers without changing table schema. Apply it through the normal migration flow. A tool-definition event can advance a runtime revision without changing the bounded assignment snapshot. Consumers still need authorized readers for definitions. Credential-only changes, grants, secrets, and endpoints remain for the access-hook migration. Profile replacement now rolls back as a unit if any entry fails. Binding and install notifications retain scoped recipients. Profile-entry changes use standing bindings, and policies use old/new agent selectors. Unscoped policies, company-bound profiles, and other conservative definition changes retain synchronous transaction-atomic company-wide fanout: O(eligible company agents) locks and journal storage, without a fanout ceiling or mutation quota. This retains the accepted tradeoff from #16603 for company-wide changes. ## Model Used OpenAI Codex, GPT-6, with reasoning, repository inspection, code execution, and testing.
