## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - People also ask agents for work in their existing chat tools.
> - Each external conversation needs one task and a current authorized
source.
> - Retries, Stop, and provider failures must not duplicate work or
expose private data.
> - The first chat PR establishes the opt-in provider and data
contracts.
> - This PR adds experimental channel integration and its durable
control plane.
> - Users can request work from connected channels and inspect delivery
in Paperclip.
## Linked Issues or Issue Description
Refs #13100 and #13092. This is the second of exactly two chat PRs.
Foundation #13100 is merged and changed 143 files. Runner prerequisite
#13092 is also merged. This PR changes 400 files against master, below
the 500-file review limit. It contains no wireframe images or HTML
galleries.
## What Changed
- Add native Slack, GitHub, Microsoft Teams, Telegram, and Discord chat
connections. Keep chat disabled unless the operator enables experimental
chat connectors. Preserve the production GitHub tool connection and its
normal setup path.
- Bind each provider bot identity to one immutable Paperclip agent. Bind
each admitted external conversation to one task. Paperclip owns tasks,
runs, permissions, and audit records.
- Add durable admission, per-conversation queues, questions, task
controls, progress, final replies, images, files, and delivery receipts.
Board comments remain internal unless explicitly sent to the channel.
- Check current identity, provider reach, resource access, credentials,
runtime generation, and exact source before provider effects. Keep
private responses private. Never send raw reasoning, private logs,
credentials, or tool arguments.
- Hold uncertain sends for explicit audited resolution. Make Board
Send-to-channel atomic and idempotent. Keep reconnect and setup
credentials in Paperclip secret storage.
- Preserve current native-runner authority across retries, lost
acknowledgements, and recovery. Keep immutable input and completion
contracts separate from newer user input. Receipt reconciliation cannot
launch a provider.
- Reconcile chat close/new ordering and provider-effect lock order.
Audit resource access changes in the same transaction. Submit only the
selected resource from each UI toggle so stale pages cannot undo
unrelated access changes.
- Drain Codex stdout before certifying process exit. Bound the drain
with the existing shutdown grace. Preserve observed terminal authority
without treating an undrained process as successful or reusable.
- Incorporate master `018ca5da` with its ACP Stop, mobile task layout,
runner packaging, and official lock changes. Preserve dedicated
chat-answer continuations in both directions when ordinary queued
comments are adopted after Stop.
- Fence late adapter readiness behind an earlier Stop for the same run.
Preserve verified cleanup for registered adapters. Handle single Stop,
agent pause, duplicate Stops, and failure release without creating a
false cancellation receipt.
- Incorporate master's `6dd48cad4` wake-queue extraction. Preserve exact
failed-chat retry authorization and lineage, retired question-source
suppression, and the block on generic recovery that would discard the
admitted source. Fresh deferred input retains its separate promotion
path.
- Incorporate master `2a05b5ed3` and its queue-admission extraction,
simplified transaction ports, and separate runner CI job. Preserve exact
durable receipts, actor separation, and dedicated-answer isolation
through the new module. A failed receipt insert rolls back the
accompanying deferred-wake merge.
## Verification
Current head: `afe19299d06253cb628eb398e91d1200ea9f412a`, incorporating
master `2a05b5ed3457ea33efd6895520447d1d97fe98d8`. The conflicts are
resolved. This successor fixes two test-harness boundaries exposed by
CI: per-case route-module preparation and actual durable-save completion
before intentional runner termination. Production code and all existing
test/turn deadlines are unchanged. [Exact-head Greptile
review](https://github.com/paperclipai/paperclip/pull/13038#issuecomment-5587250594)
is **5/5**, completed September 10 at 13:20:55 UTC, with no actionable
findings or open review threads. [Fresh exact-head
CI](https://github.com/paperclipai/paperclip/actions/runs/34481724341)
passes **all 24 jobs**, including Build and both required aggregates.
Normal exact-head guarded merge was attempted and rejected by the
remaining branch approval policy: CODEOWNER review is required and no
human approval is present. Normal **squash auto-merge is enabled** as of
September 10 at 13:36:26 UTC. Requested CODEOWNERS have been notified;
no approval bypass or self-approval was used. Earlier-head results below
remain historical evidence, not qualification of this successor.
- Final exact-head Linux evidence: 995/995 chat integration cases; 36/36
agent-skills routes; 35/35 runner live-session cases, including real
process kill/resume; 1948 runner Vitest cases with three existing
benchmark/platform guards; 870/870 API-authority cases; and 104 browser
cases with four existing optional skips. Rust, conformance/replay, full
repository build, typecheck, canary, all server/workspace shards, and
both required aggregates pass with normal CI concurrency. Earlier failed
attempts remain recorded below.
- Latest test-only qualification: 141/141
route/permissions/authentication cases pass in separate cold forks, with
plain server types and independent review clear. The real-runner suite
passes 35/35, with plain runner types and independent review clear. A
controlled premature-save acknowledgement fails as expected; matching
ownership/effect/process evidence, rejected saves, real turn outcome,
test abort, and pre-kill liveness are covered. No local reproduction of
the original CI scheduling failure is claimed. The preceding [CI
run](https://github.com/paperclipai/paperclip/actions/runs/34479680858)
passes 21/24 jobs, including all 995 Linux chat cases and browser
aggregate (104 passed, four existing optional skips); only Build, the
skills serialized shard, and the required verification aggregate fail.
Its exact-head Greptile review was 5/5. Both failed job logs are
retained.
- Final fixture qualification: all eight focused Discord cases and all
995 chat integration cases pass. The exact modal statement/PID is
observed before taking the real connection lock; the test then proves
its actual blocking relationship before mutation. Original SQL
execution, provider behavior, negative assertions, and 1s/15s timeouts
remain unchanged. Independent review is clear and test/production hashes
remain frozen. The preceding [CI
attempt](https://github.com/paperclipai/paperclip/actions/runs/34477184777)
passed 22 jobs, including Build/runner, typecheck, canary, all other
test shards, and browser aggregate (104 passed, four existing optional
skips); the two fixture failures and failed verification aggregate
remain recorded, not relabeled as a pass.
- Current queue-module composition: 308/308 recovery/batching/queue/Stop
tests; 995/995 full chat integration; 89/89 module tests, including real
PostgreSQL receipt-insert rollback; 24/24 workflow/module-boundary
tests; plain server and UI types. All four actual local process/ACP
browser paths pass in 1.4 minutes. Fresh databases, no skips or retries,
stable reviewed source hashes. The initial boundary failure is retained;
its no-op service wrapper was removed without changing recovery context
or weakening the check. An exploratory standalone test-directory
typecheck fails because its new upstream transformation config is not a
standalone typechecking project; standard CI/build does not invoke it,
and no configuration was weakened to suppress those diagnostics.
- The preceding head `e02a63d462ce5d47433b0aeb632bb6fd20aab1ba` passed
[all 24 CI
jobs](https://github.com/paperclipai/paperclip/actions/runs/34436462958)
and exact-head Greptile review at 5/5. Required CODEOWNER review
prevented its normal merge before master advanced again.
- Final extracted-module composition: 307/307 recovery, batching, queue
and Stop-control tests; 995/995 full chat integration; 49/49 module
tests including eight PostgreSQL adapter cases; and 19/19 issue-update
tests. Plain server types pass. All four actual local process/ACP
browser paths pass in 1.3 minutes. Fresh databases, no skips or retries
in these cohorts, frozen source hashes, and independent review clear.
- The preceding head `3e4e1c1c` passes [all PR CI
jobs](https://github.com/paperclipai/paperclip/actions/runs/34415826820),
including Build and required `ci / verify` and `ci / e2e`. Both the
original Rust failure and the previously load-sensitive lineage fixture
pass with unchanged Linux concurrency. Master advanced afterward and
required this reconciliation.
- Final master composition: 448/448 focused UI tests, 186/186 adapter
tests, 24/24 queue/control tests, and 11/11 packaging tests. Plain UI,
server, shared, and adapter types pass. Token gates and diff checks
pass. Independent server and UI reviews are clear.
- Stop-registration regression: both real-service cases fail against
exact `a95` source and pass with the fix. The full corrected
recovery/control suite passes 265/265. Duplicate-owner and failed-Stop
controls also pass. Plain server types pass. The readiness barrier
prevents provider startup without adding an acknowledgment to an already
terminal run.
- Final qualification strengthens terminal-field equality and repeats
both affected cases successfully on a fresh database. All four actual
local process/ACP browser paths pass again in 1.3 minutes, without skips
or retries. The final screenshot shows Cancelled, a paused subtree,
retained input, and no error toast.
- Two new actual-service regressions fail before the merge fix. They
prove that queued-comment adoption could consume a dedicated chat answer
or add unrelated input to that answer. The fixed four-case cohort
passes, including ordinary upstream continuation and adapter Stop
controls. Full recovery passes 257/257. All four actual local
process/ACP Stop browser flows pass in 1.4 minutes, without skips or
retries, on a fresh database.
- The unchanged runner artifact was qualified with 171/171 transport
tests, 870/870 API-authority tests, conformance 1/1, and replay 11/11.
Six controlled reader tests prove the exit/drain repair. Its local
serial Rust workspace passed 546 top-level cases plus two invoked
helpers; the later passing Linux CI supplies default-concurrency
evidence.
- Prior exact-source full chat integration passes 995/995. Settings
regressions cover concurrent stale pages, 501 destinations, pending
state, rejected updates, and explicit retry. These deterministic tests
do not prove live provider behavior.
- Retained failed attempts and their causes are in the [qualification
log](afe19299d0/doc/plans/chat-adapters/2026-09-08-chat-queue-and-webhook-repair.md).
The first merge adapter run timed out while macOS slept for 290 seconds.
Its unchanged repeat passed with a temporary sleep guard. No assertion,
deadline, or CI gate was weakened.
Review commands include `pnpm --filter @paperclipai/server exec vitest
run src/__tests__/heartbeat-process-recovery.test.ts
src/__tests__/issue-queued-comments-routes.test.ts` and `pnpm exec
playwright test --config tests/e2e/playwright.config.ts
tests/e2e/acp-stop-continuation.spec.ts`. Database suites require fresh
disposable databases. See the [browser
runbook](afe19299d0/doc/plans/chat-adapters/2026-09-04-chat-adapters-browser-e2e-runbook.md)
for provider setup and separate live acceptance steps.
## Risks
- This remains experimental. Deterministic tests and bounded live
evidence do not establish every provider feature, tenant, permission
layout, or media shape. Teams work-tenant qualification is still open.
- Failed and uncertain provider effects remain visible and can require
operator action. A transport receipt does not prove recipient
visibility.
- Native controller and runner artifacts must remain compatible.
Preserve lease ownership, terminal authority, source binding, and
quarantine during future changes.
- Access and audit rows commit together, but activity notifications
remain best-effort. This is not a new durable event outbox.
- The PR operation does not deploy a live server, replace its runner, or
change provider permissions. Remaining live qualification is documented
in the [temporary
handoff](afe19299d0/doc/plans/chat-adapters/2026-09-08-open-qualification-followups.md).
## Model Used
OpenAI Codex assisted with implementation, tool execution, testing, and
review. The work records `gpt-6-astra` assistance. The environment does
not report a context-window size. No private reasoning traces are

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent work is issue-centered, and reviewers often need to inspect
files, artifacts, and path references produced during that work.
> - Before this branch, workspace-relative paths and artifact file
references were not first-class inspectable objects in the board UI.
> - Safe file viewing needs shared resource contracts, server-side
workspace boundary checks, and UI that opens files without exposing
arbitrary host paths.
> - The workspace file viewer branch needed to stay as one active PR and
be rebased onto current `paperclipai/paperclip:master` for review.
> - This pull request adds the workspace file resource API, issue-page
file viewer and browser, markdown file-reference links, and artifact
file chips.
> - The benefit is that board users can inspect relevant files from
issue context while preserving workspace boundaries and auditability.
## Linked Issues or Issue Description
No public GitHub issue exists for this branch. Internal Paperclip
issues: `PAP-1953`, `PAP-10539`, `PAP-10733`.
Problem / motivation:
- Board users need to open workspace-relative files mentioned by agents
or attached as work-product metadata without switching to a terminal.
- The UI needs to support both direct file-path opening and workspace
browsing/searching from an issue page.
- The server must enforce company access, workspace boundaries, size
limits, rate limits, and safe audit logging.
Related PR:
- Prior closed attempt: #4442
- Single active PR for this branch: #7681
## What Changed
- Added shared workspace file resource types, validators, and
workspace-file `resourceRef` metadata validation for work products.
- Added server routes/services for resolving, listing, and previewing
workspace-relative files with access checks, scan caps, list-specific
limits, and audit logging.
- Added the issue file viewer provider, sheet, workspace browser,
command-palette action, markdown workspace-file autolinks, and artifact
file chips.
- Updated issue workspace UI and stories/tests for file browsing and
workspace file opening.
- Rebased the branch onto current `paperclipai/paperclip:master` and
updated the existing single PR branch.
- Addressed current-head Greptile follow-ups by applying `offset`
consistently across search/recent/changed file listings, restoring
stopped-service port ownership checks before auto-port reuse, and
stabilizing the workspace browser pagination test.
## Verification
Current local verification after rebase to `public/master`:
- `pnpm exec vitest run packages/shared/src/work-product.test.ts
server/src/__tests__/file-resources.test.ts
server/src/__tests__/instance-settings-routes.test.ts
server/src/__tests__/instance-settings-service.test.ts
server/src/__tests__/workspace-runtime.test.ts
ui/src/components/FileViewerSheet.test.tsx
ui/src/components/FileViewerSheet.copy.test.tsx
ui/src/components/WorkspaceFileBrowser.test.tsx
ui/src/components/WorkspaceFileMarkdownBody.test.tsx
ui/src/context/FileViewerContext.test.ts
ui/src/lib/remark-workspace-file-refs.test.ts
ui/src/lib/workspace-file-parser.test.ts
ui/src/components/IssueWorkspaceCard.test.tsx` - 13 files passed, 197
tests passed.
- `pnpm -r --filter @paperclipai/shared --filter @paperclipai/server
--filter @paperclipai/ui typecheck` - passed.
- `pnpm exec vitest run ui/src/components/WorkspaceFileBrowser.test.tsx`
- 1 file passed, 25 tests passed.
- `pnpm exec vitest run server/src/__tests__/file-resources.test.ts
server/src/__tests__/workspace-runtime.test.ts` - 2 files passed, 90
tests passed.
- `pnpm -r --filter @paperclipai/server typecheck` - passed.
- Confirmed branch is `0` behind and `46` ahead of current
`public/master` after rebase and follow-up commits.
- Confirmed the PR diff does not include `pnpm-lock.yaml`.
- Confirmed the PR diff does not include `.github/workflows` changes.
- Searched GitHub for duplicate or related workspace file viewer
PRs/issues; #4442 is the prior closed attempt and this PR is the single
active PR for the branch.
- No screenshots were committed; the task explicitly asked not to add
design screenshots or images unless they were part of the work.
Current remote verification on head
`a698a7bc10137baf7d25bd5722e1d6e0343387c1`:
- Greptile Review - success, 64 files reviewed, 0 comments added, no
unresolved Greptile review threads.
- PR workflow `verify` - success.
- Typecheck + Release Registry, General tests, workspace test shards,
serialized server suites, Build, Canary Dry Run, e2e, Socket, and Snyk -
success.
- `security-review` - neutral, with output saying a draft advisory was
filed for maintainer review and is not a merge block.
- `commitperclip PR Review / review` - cancelled after the security gate
detected flags and timed out while creating/reviewing the advisory. I
reran it once and it cancelled the same way; no actionable code/test
failure was exposed in the job logs.
## Risks
- This is a broad UI/server feature PR, so review needs to pay attention
to route authorization, workspace boundary handling, and markdown
autolink false positives.
- Workspace browsing intentionally caps list results and scan depth;
very large workspaces may require users to refine search terms.
- Remote workspace preview remains unavailable until remote file-access
support is implemented.
- The neutral commitperclip security-review advisory needs maintainer
review, but the check output says it is not a merge block.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected - check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
- OpenAI Codex, GPT-5 coding agent in a Paperclip/Codex local tool-use
environment, medium reasoning, with shell/GitHub CLI tool use for branch
inspection, verification, rebase, PR update, Greptile review, and CI
inspection.
