## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Runtime preparation depends on access and credential state as well as tool definitions. > - Grant, membership, secret, and endpoint changes need committed invalidation. > - Their writers must acquire locks before journal fanout can lock agent rows. > - This pull request adds access hooks with the corresponding transaction guards. > - Plugins can refresh preparation immediately while task-time authorization remains authoritative. ## Linked Issues or Issue Description **What happened?** Grant changes, credential rotation and revocation, company access changes, and connector endpoint configuration do not request runtime synchronization. Journal fanout exposes lock inversions between credential persistence, access cleanup, and connection assignment writers. **Expected behavior** Committed access changes request runtime preparation without polling or credential values in the journal. Agent-specific secret bindings and new personal delegations affect their target agent. Company access changes remain conservative. Provider bookkeeping does not create preparation work. **Steps to reproduce** 1. Change an audience, delegation, membership permission, referenced credential, vault configuration, or endpoint instruction. 2. Expect a committed runtime event in the correct company and scope. 3. Run reconnect, credential refresh, SSH setup, or membership cleanup concurrently with related writes. 4. Expect both operations to preserve access checks and finish without a lock-order cycle. **Additional context** Final feature extraction from #16503. The earlier slices, #16604, and the separate delivery-test correction #16871 are merged. This PR is now the active change against master. The rebase preserves the merged assignment and definition recipient rules, Unicode selector semantics, and profile/reference transaction guards. ## What Changed - Add migration 0356 for grants, audiences, delegation, membership/permissions, secret bindings, referenced credentials and vaults, and chat/email endpoint configuration. - Keep events content-free. Ignore health, delivery, publication, Vercel verification, and GitHub webhook bookkeeping while retaining credential and repository-access changes. - Target agent secret bindings and all personal delegation changes to their old and new target agents. Coalesce delegation changes per transaction. - Lock existing grants before connections and credential persistence in OAuth and cleanup writers. - Reject superseded refresh leases before rotating stored credentials. Ignore lease acquisition and release when access metadata is unchanged. - Serialize audience replacement, validate membership, and preserve unchanged audiences. - Lock membership before permission-only saves and grant before Railway SSH setup. Individual delegation revocation locks its grant and target. Whole-grant and membership cleanup lock company recipients before deleting scoped delegations. - Lock grants and connection inputs before static-key reconnect writes. Lock company agents before cascading secret deletion; use a nonblocking secret lock and bounded retries to avoid a new cycle with credential writers. - Add PostgreSQL concurrency coverage for access writers and endpoint publication/configuration behavior. - Preserve the owner lock for plugin instance-secret removal; these secrets cannot use ordinary bindings. - Align Slack search refresh, callbacks, and disconnect with grant-before-connection locking. Recheck newly discovered grants without waiting before provider work. - Retry complete membership transactions when a credential deletion candidate is busy. Cover all four cleanup entry points and process company access in ID order. - Document final invalidation coverage and task-time authorization boundaries. ## Verification - Current head: `78aace55bef7f52bc5742b131e0b3961eb5c0f11`. All 1,061 tests across 23 affected suites pass. The named Slack authorization integration scenario also passes; it exercises authorization, refresh, disconnect, and rejection of a late callback. Server/database typechecks, migration safety and numbering, five-snapshot retention, feature maps, and diff checks pass. The complete PR diff was reviewed for secrets and personal data before push. Final acceptance: [CI run 39308303837, attempt 2](https://github.com/paperclipai/paperclip/actions/runs/39308303837) is green, with 55 successful checks and two optional Storybook skips. The current-head Greptile reassessment returned **Apex 5/5** at 19:16 UTC on 2026-10-19. Its full summary reports no actionable issues. Security passed, all threads are resolved, and GitHub reports no merge conflicts. The reassessment was requested as a standard review after the fixes; Greptile retained the Apex tier. - On this head, [CI run 39308303837](https://github.com/paperclipai/paperclip/actions/runs/39308303837) failed the unchanged adapter-utils HTTP/2 fixture with `EADDRINUSE` before READY. Its closed probe left a port handoff race. That test and its gateway are byte-identical on master. No upstream fix was found. The deterministic fixture correction is isolated in #16888; no adapter test changes are included here. The failed jobs recovered on retry without a feature source change. The original failure remains documented here, and #16888 carries the fixture correction separately. That retry demonstrates recovery; the held-probe negative control establishes the port handoff race. - Rebased onto master `194fc11406`, including merged #16604 and #16871. Replayed only the access-hook commit. Resolved OAuth, test, and documentation conflicts while retaining both sets of tests. Migration 0356 preserves the merged assignment/definition recipient rules, Unicode selector semantics, and profile/reference guards. - Apex returned 3/5 on `0fb65bc27`. Negative controls reproduce its Slack delegation and member-cleanup deadlocks (`40P01`) and unwanted Vercel/GitHub bookkeeping events. Slack grant writers now take their locks before the connection. A separate late-grant control reproduces `40P01` without the post-lock recheck; the complete guard passes. All four membership cleanup commands retry from a fresh transaction when the credential is busy. Tests verify successful cleanup and no journal rows from failed attempts. Credential IDs and repository-access changes still notify runtimes. - Earlier review corrections remain covered: static-key reconnect and cascading secret removal each reproduce `40P01` without their guards. Grant lease acquisition/release is ignored. Secret removal releases agent locks when a credential writer is busy. Instance-secret removal retains the owner lock and passes its public plugin API contention regression. Delegation updates and revocations target old/new agents; unrelated-peer, coalescing, unchanged-update, and rollback cases pass. Three negative controls verify the required whole-grant and membership cleanup guards after narrowing delegation scope. - Preserve prior acceptance failures: the first rebased 20-suite run passed 1,025/1,026; its only failure was a draft uninstall fixture blocking a random peer. Blocking the assigned agent corrected that assumption, and all 44 access/assignment tests passed. Later, all 1,044 tests across 21 suites, [CI run 39302185527](https://github.com/paperclipai/paperclip/actions/runs/39302185527), standard Greptile 5/5, and security passed on `0fb65bc27`. That did not clear the later Apex findings described above. Draft run 38975428081 failed a server shard; its cause was not re-investigated. A later green run does not establish that earlier cause. - Local fixture corrections are recorded separately from product failures: an assignment filename filter initially matched no file; the actual suite was included in full runs. A delegation fixture omitted its required creator, and a guard run omitted a query import. The new global-access cleanup fixture now uses its own user to avoid earlier fixtures' memberships. All were corrected before publishing their final iterations. - Local checks target affected services and real PostgreSQL boundaries. A full local build and repository-wide test run were not performed. Hosted CI supplies broader verification. Provider responses in tests are controlled; live provider behavior was not qualified. ## Risks Migration 0356 adds triggers without changing table schema. Apply it through the normal migration flow. Most access changes retain synchronous company-wide invalidation. Company fanout takes O(eligible company agents) locks and journal rows, without a fanout ceiling or mutation quota. Agent secret bindings and individual delegation changes retain narrower recipients. Events contain no credentials. Physical removal of non-instance secrets takes ordered locks on all company agents before cascading into bindings. This costs O(company agents) locks even for an otherwise unreferenced secret. Instance secrets cannot use ordinary bindings and retain their owner lock. A busy secret lock releases the transaction guards and retries up to three times. Continued contention returns a retryable conflict. Provider deletion stays outside that transaction; a retry resumes removal of an already disabled secret. Membership cleanup uses nonblocking credential guards and retries the full membership transaction. Slack search adds two grant queries, scoped to the subject and connection. Its retries occur before provider work or credential persistence. Each retry loop is limited to three attempts. Invalidation requests preparation; task-time authorization and provider session activation remain authoritative. Provider calls use fixtures; no live provider qualification is claimed. ## Model Used OpenAI Codex, GPT-6, with reasoning, repository inspection, code execution, and testing.

App access and action permissions
After connecting an app, an operator decides which agents may use it and whether each action is off, requires approval, or is allowed. Activity and action tests help verify the resulting access.
Implementation: app detail, permissions, activity.
Agent access: companion.
Sub-features
agent-access: grant the connection to all or selected eligible agents.action-policy: set off/ask/allowed independently for available actions.catalog-change: review newly discovered/quarantined actions before enabling them.test-action: choose an actor and inputs and inspect a real action result.account-maintenance: inspect accounts, reconnect/revoke, and review connection activity.
How to get to it (user POV)
permissions
Open an app at /apps/:connectionId/permissions; this is the default connected-app view.
test-and-maintain
Use the action test control in Permissions, then the connection’s Activity and available account/advanced controls.
Driving it
Preconditions: follow the baseline. Prepare a connection to a fixture or test provider, two agents, and a harmless action. Record provider and credential ownership.
permissions
Automated: app detail covers agent/action controls, quarantined actions, and navigation using mocked requests.
Runtime assignment tests
use PostgreSQL to verify committed assignment notifications, bounded snapshots,
rollback, and concurrent AI adoption. The owning lifecycle plugin can read
standing assignments through ctx.agents.getRuntime; this does not grant tool
execution access or replace task-specific authorization.
Tool-definition runtime tests cover catalog invalidation, scoped policy/profile-entry recipients, ignored bookkeeping, profile-entry edits concurrent with setup finalization, and profile replacement concurrent with application deletion using PostgreSQL. They do not qualify live provider access.
Connector access runtime tests cover grants, delegation, membership cleanup, referenced vault changes, and agent-scoped secret bindings. OAuth and Railway tests exercise the corresponding credential lock order. Slack search and membership cleanup tests cover lock contention and complete transaction retries. Provider calls use fixtures; no live credentials are qualified by this coverage.
Manual: Grant one agent access, leave another excluded, and exercise off, ask, and allowed states for a harmless action. Reload between changes. Verify actual denied calls stay denied and ask-first creates a decision rather than executing early.
test-and-maintain
Automated: app detail tests cover test-dialog/UI contracts. Real provider execution and revocation require the selected provider’s live check.
Manual: Run a read-only action with explicit inputs and inspect returned data and activity. Refresh discovery and review new actions. Revoke or disconnect only the disposable credential, then verify subsequent use fails with an actionable reconnect state.
For Daytona, opening an older saved catalog discovers the current native contract. Removed diagnostic actions disappear from Permissions and agent discovery; new or changed actions require review. Existing Off/Allowed choices remain in place. Daytona regressions cover shared/personal catalog upgrades, failed refresh, permission preservation, run-bound file transfers, and revocation with fixture provider responses.
Gotchas
- Connected does not imply an agent has access or an action is allowed.
- Credential-only connections may replace tool-action controls with account-specific controls.
- See connection setup for auth and questions and approvals for pending action review.
Storybook verification
catalog-change
Scope: ui Storybook: Mount PermissionsPanel/AppDetail with quarantined actions, selection/review, refresh pending, empty and failed discovery states. Existing auto-allowed NewToolsAllowed examples are not quarantine review. Production: Exercise catalog refresh and new-tool review with permitted/denied actors; unreviewed actions stay quarantined, prior Off/Ask choices survive refresh, and approved review persists.
