## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Conversations must use the same tasks, controls, and execution
history.
> - Users need an ongoing chat with an agent without managing task
properties.
> - Agents should clarify and plan work, then hand execution to assigned
project tasks.
> - This pull request combines the reviewed Agent Chat stack for one
squash merge.
> - The benefit is persistent conversation with normal task governance
and shared UI.
## Linked Issues or Issue Description
**Subsystem affected**
Task lifecycle, agent runtime tools, shared task UI, and browser/paid
runner tests.
**Problem or motivation**
Users need one persistent conversation with each agent. A separate chat
store or renderer would duplicate task behavior and bypass existing
controls.
**Proposed solution**
Use a task-backed chat per company, user, and agent. Reuse the task
composer and transcript. Clarify and plan in chat, then create assigned
project tasks with the relevant plan. Keep Agent Chat behind its own
disabled-by-default experimental setting.
**Roadmap alignment**
This implements the task-backed direction in [CEO
Chat](https://github.com/paperclipai/paperclip/blob/master/ROADMAP.md#-ceo-chat).
Related proposals: #2504 and #9693. Related request: #7981. The
maintainer requested one squash merge of the complete stack.
Consolidates the reviewed runtime
[#13281](https://github.com/paperclipai/paperclip/pull/13281), backend
[#13282](https://github.com/paperclipai/paperclip/pull/13282), and UI
[#13283](https://github.com/paperclipai/paperclip/pull/13283) layers
with this PR's E2E coverage. All four layers passed CI and received
Greptile 5/5 before consolidation. This PR targets master and includes
the complete feature.
## What Changed
- Add personal canonical chat tasks with ordinary company visibility,
immutable identity, idempotent first sends, and an idle waiting state.
- Process `/new` in queue order. Preserve history, release a chat pause,
and fence old provider context and delayed writes.
- Keep chat lifecycle rules across recovery, finalization, assignment,
task lists, and rollups.
- Support research and plan revision in chat. Hand plans to ordinary
assigned project tasks before execution starts. Reject new chat
subtasks.
- Add repository-aware project creation and discovery tools, including
multiple repository IDs and GitHub URLs, authorization, idempotency, and
durable project-created cards.
- Reuse task UI components for chat, with starred/recent agent
navigation and a separate `enableAgentChat` experimental flag.
- Add deterministic browser tests and 24 paid chat cells across four
Codex/Claude profiles, with validated reports and screenshots.
- Integrate current master recovery, controller lease, queued-message,
and task UI changes. Gate chat interruption and deferred promotion on
ownership/feature policy. Guarantee lease renewal and active controls
are stopped even if teardown fails.
- Preserve master's migration 0273 and generate chat migration 0274 with
idempotent replay for development databases.
## Verification
- Prior exact heads of all four PRs passed Linux CI, including build,
typecheck, general/serialized tests, and browser E2E. Each had Greptile
5/5 and no unresolved findings.
- Integrated local verification passed: full repository typecheck and
production build, Storybook build, token gates, 340 focused UI tests,
all 20 deterministic chat browser tests, two migration replay tests, 88
focused chat/queue/native/controller tests, and provider/session
regressions including real lease expiry. These include the three
lifecycle regressions for the final admission/teardown fixes; server
typecheck also passes. Current head
`1268eda16cc2af892055917e7292f068820be135` has Greptile 5/5 with no
unresolved findings and passing security scans. All final-head CI gates
passed: build, full Runner verification, typecheck/release registry,
canary, all general/serialized test shards, and all browser E2E shards
([CI
run](https://github.com/paperclipai/paperclip/actions/runs/34696739927)).
Local PostgreSQL startup contention required serialized retries; skipped
fixtures do not count as passing coverage.
- The earlier paid campaign passed all 24 chat cells and retained 32
screenshots:
[report](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-34648511170-1/index.html?report=agent-chat#suite-agent-chat).
It tested `abacbdfd2f660709ec37312cdb758284c8399d04`; it is prior
evidence, not a paid run of this integrated head.
- Manual check: enable Agent Chat in Experimental settings, open an
agent, clarify and revise a plan, then hand off to an assigned project
task. Stop a reply, send `/new`, and verify fresh context with retained
history. Disable the setting and verify agent shortcuts/new chat turns
are blocked.
## Risks
- Queue/session integration can affect retries and delayed writes. Tests
cover ownership, cancellation, reset boundaries, idle recovery, and
ordinary task behavior.
- Migration 0274 adds conversation fields and constraints. Replay is
idempotent and preserves existing development chat history.
- This combines the previously reviewed stack at the maintainer's
request. Agent Chat remains off by default and is separate from
Conference Room.
## Model Used
OpenAI Codex, GPT-6 Astra (`gpt-6-astra`), with reasoning, code
execution, browser tools, and parallel review. The exact context-window
size is not exposed in this session. Codex and Claude also ran as test
subjects in the linked paid campaign.

## Thinking Path
> - Paperclip's `claude_local` adapter persists Claude Code session
jsonls under `~/.claude/projects/…/{sessionId}.jsonl` and resumes them
on the next heartbeat
> - When Claude Code injects `<synthetic>` placeholder assistant
messages (after rate-limit, max-turn exhaustion, or transient-upstream
failures) those placeholders get UUID-format `message.id`s rather than
`msg_…`-format ids
> - On the next `--resume`, Claude Code passes that UUID as
`previous_message_id` and Anthropic's API rejects it with a 400:
``diagnostics.previous_message_id: must be the `id` from a prior
/v1/messages response (starts with `msg_`)``
> - The adapter had a session-rotation fallback only for "unknown
session" errors, so the poisoned session was `--resume`-d indefinitely
and the agent flipped between `idle` and `error` every heartbeat
> - Even worse, the *result* event of the failing run still carried a
`session_id`, and the adapter was persisting that id into the
issue-scoped session store (`agentTaskSessions`). So even after we
detected the 400, every subsequent continuation re-loaded the same
poisoned id and hit the same 400 again — the issue was permanently
stranded
> - We observed this on multiple agents in our deployment; the only
manual fix was to rename the `.jsonl`, which is not a viable long-term
workaround
> - This PR detects the 400, runs the same session-rotation fallback the
unknown-session path uses **and** stops persisting the poisoned id, so
the next attempt starts genuinely fresh
## Linked Issues or Issue Description
No external GitHub issue is linked. Describing the problem inline
following the bug-report template:
**What happened:** `claude_local` agents flipped between `idle` and
`error` on every heartbeat because the persisted session jsonl carried a
synthetic UUID `previous_message_id` (from `<synthetic>` assistant
placeholders injected after rate-limit/max-turn/upstream errors).
Anthropic's API rejected every `--resume` with a 400:
``diagnostics.previous_message_id: must be the `id` from a prior
/v1/messages response (starts with `msg_`)``.
**Expected behavior:** When the persisted session is poisoned and
unrecoverable, the adapter should rotate to a fresh session — the same
fallback path already used for unknown-session errors — and stop
re-persisting the poisoned `session_id`.
**Actual behavior:** The session-rotation fallback only matched the
"unknown session" pattern, so the poisoned session was `--resume`-d
forever. The result event of the failing run still carried `session_id`,
which was being persisted into `agentTaskSessions`, so every subsequent
continuation reloaded the same poisoned id and hit the same 400.
**Reproduction:** Inject any flow that causes Claude Code to emit a
`<synthetic>` placeholder (rate-limit, max-turn exhaustion, transient
upstream failure). The next `--resume` will fail with the 400 and the
agent will not self-recover.
**Scope of fix:** Add a `previous_message_id` 400 detector; route it
through the existing unknown-session fallback; drop the poisoned
`sessionId` and emit `clearSession: true` so the heartbeat service wipes
the persisted row; best-effort delete the local poisoned `.jsonl`.
## What Changed
Two commits:
1. **`adapter-claude-local: auto-rotate session on previous_message_id
400 (synthetic-msg poisoning)`** — detector + execute-time rotation
2. **`adapter-claude-local: guard against persisting poisoned
sessionId`** — validate-before-persist + `clearSession`
Combined diff:
- `parse.ts`: new `isClaudePoisonedPreviousMessageIdError(parsed)`
matching ``/diagnostics\.previous_message_id.*starts with `msg_`/i``
against `parsed.result` and `extractClaudeErrorMessages(parsed)`
- `parse.ts`: `isClaudeTransientUpstreamError()` excludes the new error
from transient classification so it isn't masked as retryable upstream
noise
- `execute.ts`: expand the resume-fallback branch so it triggers on both
`isClaudeUnknownSessionError` and the new
`isClaudePoisonedPreviousMessageIdError`, with a distinct log line
(`"returned a poisoned message-id"` vs `"is unavailable"`)
- `execute.ts`: for local (non-remote) execution targets, best-effort
delete the poisoned `~/.claude/projects/.../{sessionId}.jsonl` before
retrying so the file can't be accidentally resumed by an out-of-band
caller. The `fs.unlink` and follow-up log call are in separate try/catch
blocks so a closed log stream cannot mask a successful unlink (and vice
versa)
- `execute.ts` / `toAdapterResult`: when a result carries the poisoned
400, **drop** `sessionId`/`sessionParams`/`sessionDisplayId` (return
`null`) and emit `clearSession: true` so the heartbeat service's
`resolveNextSessionState` wipes the persisted row. The result also
surfaces `errorCode: "claude_poisoned_previous_message_id"` for
observability
- `docs/adapters/claude-local.md`: runbook entry — symptom,
auto-recovery flow, on-call checklist
- Tests:
- 4 new `parse.test.ts` cases covering positive detection in `result`
and `errors[]`, negative cases, and non-transient classification
- 3 new `claude-local-execute.test.ts` cases: (a) fresh run reports the
poisoned error → sessionId dropped + `clearSession: true`; (b) recovery
retry also reports the poisoned error → same guards apply; (c)
session-rotation success on retry
## Verification
```bash
pnpm --filter @paperclipai/adapter-claude-local exec vitest run src/server/parse.test.ts
pnpm --filter @paperclipai/server exec vitest run src/__tests__/claude-local-execute.test.ts
```
Both suites green locally. This patch is also currently running as a
hot-patch over the published `2026.513.0` adapter on the reporting
deployment — sessions that previously looped indefinitely now
self-recover on the first heartbeat after the 400 surfaces.
## Risks
- Low risk. The detector is conservative (regex over `result` +
`errors[]` only) and the rotation reuses the existing unknown-session
fallback path
- The local-only `fs.unlink` of the poisoned `.jsonl` is wrapped in
`try/catch` and ignored on failure — strictly an optimization; the
server-side session clear is the authoritative reset
- Remote execution targets (`executionTargetIsRemote`) skip the disk
cleanup because the file lives on a remote host that we can't safely
reach from the adapter
- The `clearSession: true` + nulled session fields path is a no-op on
healthy runs; it only fires when the new detector matches, so existing
successful continuations are unaffected
- No DB schema changes, no public API changes, no new dependencies
## Model Used
- Provider: Anthropic Claude
- Model: `claude-opus-4-7` (Opus 4.7)
- Context window: 1M
- Capabilities: extended reasoning, tool use, code execution
- Role: implemented the detector, expanded the fallback branch, added
the persist-guard + `clearSession`, wrote the unit + integration tests,
validated locally, and applied the equivalent hot-patch to the deployed
`2026.513.0` install while this PR is in review

## Thinking Path
> - Paperclip is the control plane for autonomous AI companies.
> - V1 needs to stay local-first while also supporting shared,
authenticated deployments.
> - Human operators need real identities, company membership, invite
flows, profile surfaces, and company-scoped access controls.
> - Agents and operators also need the existing issue, inbox, workspace,
approval, and plugin flows to keep working under those authenticated
boundaries.
> - This branch accumulated the multi-user implementation, follow-up QA
fixes, workspace/runtime refinements, invite UX improvements,
release-branch conflict resolution, and review hardening.
> - This pull request consolidates that branch onto the current `master`
branch as a single reviewable PR.
> - The benefit is a complete multi-user implementation path with tests
and docs carried forward without dropping existing branch work.
## What Changed
- Added authenticated human-user access surfaces: auth/session routes,
company user directory, profile settings, company access/member
management, join requests, and invite management.
- Added invite creation, invite landing, onboarding, logo/branding,
invite grants, deduped join requests, and authenticated multi-user E2E
coverage.
- Tightened company-scoped and instance-admin authorization across
board, plugin, adapter, access, issue, and workspace routes.
- Added profile-image URL validation hardening, avatar preservation on
name-only profile updates, and join-request uniqueness migration cleanup
for pending human requests.
- Added an atomic member role/status/grants update path so Company
Access saves no longer leave partially updated permissions.
- Improved issue chat, inbox, assignee identity rendering,
sidebar/account/company navigation, workspace routing, and execution
workspace reuse behavior for multi-user operation.
- Added and updated server/UI tests covering auth, invites, membership,
issue workspace inheritance, plugin authz, inbox/chat behavior, and
multi-user flows.
- Merged current `public-gh/master` into this branch, resolved all
conflicts, and verified no `pnpm-lock.yaml` change is included in this
PR diff.

- Confirmed branch has no uncommitted changes and is `0` commits behind
`public-gh/master` before PR creation.
- Confirmed no `pnpm-lock.yaml` change is staged or present in the PR
diff.
## Risks
- High review surface area: this PR contains the accumulated multi-user
branch plus follow-up fixes, so reviewers should focus especially on
company-boundary enforcement and authenticated-vs-local deployment
behavior.
- UI behavior changed across invites, inbox, issue chat, access
settings, and sidebar navigation; no browser screenshots are included in
this branch-consolidation PR.
- Plugin install, upgrade, and lifecycle/config mutations now require
instance-admin access, which is intentional but may change expectations
for non-admin board users.
- A join-request dedupe migration rejects duplicate pending human
requests before creating unique indexes; deployments with unusual
historical duplicates should review the migration behavior.
- Company member role/status/grant saves now use a new combined
endpoint; older separate endpoints remain for compatibility.
- Full production build was not run locally in this heartbeat; CI should
cover the full matrix.
## Model Used
- OpenAI Codex coding agent, GPT-5-based model, CLI/tool-use
environment. Exact deployed model identifier and context window were not
exposed by the runtime.
