DottaandPaperclip 297d8741f5 fix: resolve duplicate connections to the same GitHub account (#13022)
## Thinking Path

> - Paperclip lets people share agents while keeping GitHub access
personal.
> - Each managed Git or GitHub operation selects an eligible connection
grant.
> - Connecting the same GitHub account twice creates two grants.
> - The old resolver counted grants and rejected them as competing
identities.
> - Managed commands then ran anonymously and reported a misleading
login failure.
> - This change compares GitHub account IDs and selects one eligible
grant for the same account.
> - The benefit is reliable access after reconnecting, with clear
diagnostics for real failures.

## Linked Issues or Issue Description

Refs #13005.

**What happened?**

Two active connections owned by one Paperclip user pointed to the same
GitHub account. Managed Git refused both as ambiguous. The agent could
not push, although the account was connected and had repository access.

**Expected behavior**

Multiple grants for the same GitHub account resolve to one eligible
authorization. Different accounts remain ambiguous. Unavailable access
explains its cause without blocking unrelated work.

**Steps to reproduce**

1. Connect the same GitHub account twice for one Paperclip user and
allow the shared agent through both connection audiences.
2. Start an instruction as that user.
3. Run managed gh or git push. Before this fix, no credential is
provided.

## What Changed

- Compare stable GitHub account IDs when more than one eligible grant
exists. Never deduplicate by login alone.
- Prefer an available grant, then the newest authorization with a stable
ID tie-breaker. Refresh and webhook timestamps do not change the
selection.
- Keep the selected credential and connection policy together. Do not
combine permissions or fall back from a dedicated account to a personal
account.
- Print the redacted unavailable reason in managed command output.
Unrelated local operations still work anonymously.
- Add database and executable launcher regressions, and document
selection behavior.

## Verification

- Final `pnpm -r typecheck` and `pnpm build` passed.
- Fourteen operation credential integration tests passed, covering
duplicate personal/dedicated grants, incomplete credentials, distinct
accounts with the same login, missing identity metadata, revocation,
membership, connection audiences, and A → B → A steering. Existing Git
credential and gateway suites and both executable launcher tests also
passed.
- The local broad test run encountered three embedded-Postgres lifecycle
timeouts and stale modules from edits made during that run. A fresh
process rerun of all four affected suites passed all 35 tests. The full
Node 24 CI test matrix passed on the final commit.
- CI passed all 31 checks on `797973b30beb16ba5fa69ed281835e1ab812b449`
(Storybook visual regression was correctly skipped). An unrelated
Company Settings UI test failed once; the focused local reproduction and
rerun of its CI shard both passed without code changes.
- Fresh Greptile review of the final commit: 5/5, with no open findings.
Security checks passed.
- Live acceptance passed with both duplicate connections enabled:
managed `gh api user` returned the expected account, managed `git push`
succeeded, and the agent created #13023 and pushed its review fixes. No
host login or credential changes were used.
- Applied the final source/compiled patch to the affected instance with
backups, after confirming no runs were active. Restarted service health
and the final resolver selection were verified. The patch is an overlay
on the existing deployment; this PR supplies the upstream fix.

## Risks

The resolver selects one authorization for an already permitted GitHub
account. It does not combine repository permissions across connections.
If the selected authorization has narrower access, that operation can
still be denied by GitHub. Different provider account IDs and unknown
duplicate identities continue to fail closed. No schema, host
credential, or connection permission changes are included.

## Model Used

OpenAI GPT-6 through Codex assisted implementation and verification with
shell, database, and browser tools. The exact model variant and
context-window size are not exposed in this session.

Raw Blame History

GitHub identity during agent execution

Shared agents use the GitHub connection of the person whose accepted instructions they are executing. Task ownership remains unchanged. GitHub is optional: ordinary work can start without a connection; a private checkout, authenticated API call, or commit can fail when that operation needs credentials or author metadata.

Accepted instructions and continuations

run_identity_contexts records ordered revisions, stored message authors, originating causes, parent contexts, acceptance state, and redacted GitHub outcomes. heartbeat_runs.active_identity_context_id selects the current revision. Existing historical runs are not backfilled with inferred authorship.

Human messages use their stored authenticated author. Queued messages retain their delivery order. Accepting steering reserves a pending revision before delivery, then activates it after the provider acknowledgement. Rejected delivery leaves the prior revision active. An uncertain acknowledgement holds new credential acquisition; a later acknowledgement or its authenticated native event receipt reconciles the reservation. Replays cannot reactivate an older revision. Activation locks the task before the run, matching task and queue mutations so concurrent status changes cannot deadlock identity initialization.

Delegated work and interactions persist their originating context. Retries retain the originating run's active context. Background continuations carry their source run; dependency wakes use the task's continuation context, independently of its owner. Scheduled and webhook routines use the routine's responsible person; manual invocations use the caller, and edits preserve the routine's responsible person.

Managed GitHub operations

New executions receive token-free git and gh launchers and a run-scoped capability. Each launcher invocation requests the active context through the authenticated runtime transport and resolves one eligible credential at operation start. A gh command's child Git processes inherit that command's captured identity. Later steering does not change already-started operations. When a subsequent run resumes a settled native conversation, the controller starts a fresh provider process with that run’s capability and rebinds its token-free launcher paths. The durable conversation and protected provider settings remain unchanged. Local and remote durable runners complete their bounded suspension before the controller releases the session for the next run, so a queued continuation cannot race unfinished cleanup.

The broker endpoint rejects browser origins and session cookies, validates a distinct signed runtime scope, and rechecks the company, agent, and live run. Sandboxes relay the capability through the existing authenticated callback bridge. Tokens are returned only to the managed command process. They are not persisted in identity history or injected into the long-lived provider process.

Server-side Git operations and GitHub gateway calls follow the same selection rules. Approved gateway operations retain their signed originating identity. Connection audience and tool policies continue to apply to the selected person's connection. Native catalogs remain stable across identity changes, but each invocation resolves the selected grant again. Personal OAuth secret declarations survive connection pauses and metadata edits.

Managed commands disable ambient Git credential helpers, Git global/system configuration, host GitHub CLI configuration, and host SSH identity access. Per-operation GitHub CLI configuration is isolated in a writable configuration directory beneath the managed launcher directory. Missing credentials clear previous author and token values; no teammate, standing delegation, host token, or company-default user's account is substituted. Anonymous/local operations remain available where supported.

Scripts that previously read a persistent GH_TOKEN must use managed git, gh, or GitHub gateway tools. Managed execution skips legacy GitHub token bindings in agent, environment, project, and routine configuration before secret preflight. Configure personal or dedicated access through the GitHub connection instead. Directly invoking an unmanaged executable or retaining a token obtained during an earlier invocation is outside the managed invocation contract.

Dedicated accounts and diagnostics

An explicit dedicated-agent grant overrides personal selection. Revoked, disabled, unavailable, or ambiguous dedicated grants do not fall back to a person's account. Removing the dedicated configuration restores personal selection.

Connection setup and permissions display: “This agent uses this GitHub account for everyone's work, instead of the person giving instructions.”

Multiple eligible connections for the same GitHub account are treated as one identity, using GitHub's stable account ID rather than its login. The resolver selects an available grant, preferring the newest authorization with a stable ID tie-breaker. Duplicate eligibility includes an active credential record with the correct owner, the OAuth access-token reference, and repository access metadata. It keeps that grant's credential and connection policy together; it does not combine repository access or bypass connection audiences. Distinct accounts or unidentifiable duplicate grants remain ambiguous. Managed commands print the redacted reason when GitHub access is unavailable, while unrelated local operations can still proceed without credentials.

Run details show identity revisions and redacted GitHub results: responsible person, selected login when available, personal/dedicated source, and an unavailable reason. Tasks do not receive an additional identity indicator or takeover action.

Deployment and verification

Deploy the schema, server broker, launcher staging, and runtime environment contract together. Already-running processes retain their original environment; only newly dispatched processes receive the broker contract. Run-scoped capabilities remain valid only while their bound run is active.

Focused coverage lives in run-identity.test.ts, github-operation-credentials.test.ts, and github-launcher.test.ts, alongside the native steering, gateway, routine, and callback-bridge suites. Live acceptance additionally requires two authenticated Paperclip users, two authorized GitHub accounts, and a designated disposable repository for push verification. Local commit metadata and mocked API results do not replace that live push test.

Release procedure

  1. Back up the instance database using the normal deployment procedure.
  2. Build and deploy one revision containing migrations 0240–0245, the server broker, managed launchers, and the runner artifacts. Run the standard pending-migration check before admitting new runs. These additive migrations are safe to replay and do not infer authorship for historical runs.
  3. Let pre-rollout executions finish with their original runtime contract. New executions must have an active identity context and the managed launcher capability before provider startup.
  4. Check one ordinary run without a GitHub connection, then an authenticated GitHub operation. Inspect the run details for the responsible person and credential outcome. Verify a queued continuation on the same conversation.
  5. If rollback is needed, finish or explicitly stop executions using the new broker before removing its endpoint. Keep the additive schema and identity history. Do not drop identity columns or tables to roll back application code.

Remote acceptance uses the existing paid runner workflow with a narrow selection. Run it against the same immutable revision as the release; a successful local test does not qualify a different remote runner artifact.

Identity history survives deletion of the originating agent or run, so surviving subtasks and approvals retain their responsible person. The company foreign key and company-deletion service remove these company-scoped records when their company is deleted. Completed runs remove their managed launcher files before releasing a remote environment; same-run recovery retains them until the terminal boundary. Cleanup failures are logged and do not change the run result.
