DottaandPaperclip c723bb4dfc fix(skills): reuse validated runtime revisions during preparation (#13042)
## Thinking Path

> - Paperclip manages AI agents and prepares their runtime inputs before
each turn.
> - Shared company skills are part of those inputs for native and legacy
adapters.
> - Runtime materialization refreshed the full inventory again for every
declared file.
> - Remote skill directories were also downloaded and rebuilt on every
turn.
> - Measured preparation took 42–73 seconds while runner execution took
7–9 seconds.
> - This change reads the inventory once and reuses validated installed
revisions.
> - Agents retain their selected skills while repeated preparation
avoids upstream work.

## Linked Issues or Issue Description

**What happened?**

One 114-skill preparation performed 407 inventory refreshes, 48
directory rebuilds, and 388 GitHub file fetches. Reusing existing local
copies took 151 ms.

**Expected behavior**

Each listing refreshes inventory once. Unchanged installed remote
revisions reuse complete, validated local copies. Local edits remain
visible. Explicit updates select new revisions.

**Steps to reproduce**

1. Import GitHub skills with supporting files.
2. Run an agent turn, then run another with the same installed
revisions.
3. Observe repeated inventory scans, downloads, and runtime directory
replacement before execution.

Related prior attempts: #2330 and #9268 (still open; #9268 last updated
July 9). Those use a marker compared with `updatedAt`. This patch
follows the required content validation, immutable revision, company
isolation, atomic publication, and read-only semantics, and removes
refresh-per-file multiplication.

## What Changed

- Split public file reading from reading an already loaded skill.
Runtime listing refreshes inventory once.
- Add a company-scoped revision cache with file manifests outside the
delivered skill directory. Fingerprints omit cosmetic metadata.
- Validate exact file inventory, sizes, and hashes before warm reuse.
Reject traversal and symlinks. Stage complete builds and serialize
atomic publication across processes.
- Preserve local/catalog direct sources, stored Markdown fallback,
explicit version snapshots, and legacy mutable-ref compatibility. Report
missing supporting files and keep older valid revisions readable.
- Clean both runtime layouts on rename/removal and record
`skills.prepare` under preparation timing.
- Add service/cache regressions and an isolated 114-skill benchmark,
including a new-process warm run.

## Verification

- Final targeted skill-service/cache/trace validation: 86 tests pass (61
embedded-PostgreSQL service tests, 19 cache tests, 6 trace tests).
Database tests executed rather than skipped. Focused skill routes,
adapter selection, and native runtime context also pass.
- `pnpm -r typecheck` and `pnpm build` pass locally at `22caa1fe4`.
- The full `pnpm test:run` matrix passes on supported Linux CI at the
final head: [CI
run](https://github.com/paperclipai/paperclip/actions/runs/34236097762).
Local full-suite execution encountered PostgreSQL startup contention, a
random allocated-port boundary, and a socket hang-up; every affected
suite passed on an isolated rerun. The interrupted local serialized run
is not claimed as a complete local pass.
- Repeatable benchmark: `pnpm --filter @paperclipai/server exec tsx
../scripts/benchmark-skill-preparation.ts`. Mixed 114-skill inventory
with 429 remote files on Linux: cold 286 ms, warm median 96 ms / maximum
153 ms including a new process. Every warm sample performs one refresh,
zero upstream fetches/rebuilds, and reports no missing entries; content
assertions pass.
- Controlled deployment against the previously deployed revision
completed with zero lost runs. Real inventory: 114 skills, 670 declared
files; 402 cached files match the prior installed copies byte-for-byte.
Ten post-deployment warm preparations: median 129 ms / maximum 208 ms;
new-process warm 194 ms, zero downloads/rebuilds/missing entries.
- Five sequential real browser questions persisted in 10.6–20.7 s
(median 12.2 s), versus 50–83 s before. Skill preparation median 240 ms,
with one 2.37 s outlier. Total preparation median 3.337 s / maximum
8.728 s **does not fully meet** the <3 s / <5 s target. The excluded
historical-run redaction query takes about 1.36 s per scan at two
preparation call sites; wider application latency coincided with the
outlier, without a cache rebuild. These residuals are reported rather
than discarded.
- Disposable skill reimport verified through actual selected-skill runs:
the next run read the changed code. Fixture removed and agent
configuration verified unchanged.
- Greptile 5/5, zero unresolved review threads, all final-head CI checks
green.

## Risks

- Cold preparation still requires upstream availability for supporting
files. An unavailable revision is reported missing and never falls back
to an older revision.
- Valid older revisions and quarantined invalid entries consume additive
disk space until skill cleanup. An abruptly killed publisher can leave a
lock that requires operator cleanup after confirming its PID is dead.
- Warm validation reads all cached file bytes. Very large inventories
still have proportional local I/O cost.
- No HTTP API, schema, agent configuration, or first-party Telemetry
changes. OpenTelemetry retains its operator endpoint gate.

## Model Used

OpenAI GPT-6 in Codex, with reasoning, repository inspection, code
editing, and test execution. The exact serving snapshot and
context-window size are not exposed in this session.

DottaandPaperclip 1cc45086d3 feat: use the responsible person's GitHub for shared agent operations (#13005)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Several people can send instructions to the same agent and task.
> - A fixed GitHub token in the provider process can keep the first
person's access after another person's message is accepted.
> - Task ownership cannot select credentials for each accepted
instruction or preserve the identity of an operation already in
progress.
> - This pull request records ordered execution identity contexts and
resolves credentials when managed Git, gh, or GitHub tools start.
> - The benefit is automatic personal GitHub access for shared agents,
with durable continuation rules and no teammate credential fallback.

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting: orchestration, connection grants, database, runtime
adapters, native runners, and run details.

**Problem or motivation**

A shared agent must use the person whose instructions it has accepted. A
queued message must retain its author. A retry or approval without new
instructions must retain the originating identity. GitHub must remain
optional for ordinary work.

**Proposed solution**

Persist execution identity separately from task ownership. Give new
processes a run-scoped broker capability and token-free managed
launchers. Capture identity at operation start. Keep an explicit
dedicated-agent grant as an override. Show redacted diagnostics in run
details.

**Alternatives considered**

Per-task ownership, fixed provider tokens, and mutable repository author
configuration do not handle accepted steering or concurrent operations.
A manual account-selection action would add unnecessary setup to each
turn.

**Roadmap alignment**

This completes the existing Multiple Human Users, MCP Tool Gateway &
Apps, Secrets Manager, and Self-healing Runs capabilities. The
implementation follows the maintainer-approved plan.

Related work: Refs #12843, Refs #12907. Existing proposals #4618 and
#8945 cover per-agent or per-worktree author configuration. This change
instead follows the accepted human instruction across runtime types.
Refs #11831 for governed personal connection delegation; this change
preserves connection audience checks and does not use standing
delegation as a personal credential fallback.

## What Changed

- Add durable, ordered identity contexts and active run references.
Preserve message authors through consolidation, steering, retries,
delegation, approvals, routines, and restart.
- Add an authenticated operation-time GitHub credential broker and
local/remote managed git and gh launchers. Keep personal tokens out of
the long-lived provider process.
- Resolve GitHub gateway and server-side Git operations through the same
responsible-person or dedicated-grant selection rules.
- Make absent and unavailable GitHub credentials non-blocking at generic
startup. Clear host and prior-person credentials. Keep anonymous Git
access where supported.
- Add run-detail identity history and the dedicated-account warning.
Keep task ownership and queue-versus-steer decisions unchanged.
- Preserve personal OAuth declarations through connection edits. Retain
exact selected grants in the gateway.
- Fix continuation races found during real acceptance: verify a warm
owner before credential rotation, and wait for bounded durable runner
suspension before the next run starts.
- Make migrations replay-safe. Retain identity through agent/run
deletion, remove it with its company, and clean terminal launcher
directories before releasing execution environments. Document
coordinated release and rollback.

## Verification

- Full workspace typecheck, build, and token gates passed. The complete
local suite passed in its normal test groups: 17,120 passing tests,
including all 143 serialized server suites. After integrating the newly
merged runner API work, full local typecheck and build passed again,
along with 890 focused integration tests. All 31 checks on the
integrated revision passed, including build, browser E2E, release
registry, canary dry run, typecheck, security and all test suites.
Greptile is 5/5 with all review threads resolved.
- Current focused checks passed: 142 native executor tests, 67 runtime
lifecycle tests, 9 durable identity tests, 75 credential/routine tests,
19 low-trust/resumption tests, and the executable migration replay test.
- Authenticated browser acceptance with two Paperclip users and two
GitHub accounts on one shared native agent passed. Real commits and
pushes followed A → B accepted steering → queued A continuation in the
same saved conversation. GitHub commit author and committer identities
matched all three operations. Both runs succeeded and task ownership
stayed unchanged.
- Real GitHub MCP calls switched from A to B after accepted steering. A
delegated subtask retained its originating identity across a server
restart.
- Disabling B's GitHub connection left ordinary work successful. Managed
gh was unauthenticated and the provider had no inherited GH_TOKEN or
GITHUB_TOKEN.
- The browser displayed run-detail diagnostics and the exact
dedicated-account warning. A final controller-restart check followed by
another-person continuation retained the conversation, selected the
correct GitHub login and Git author, and removed each terminal launcher
directory.
- Company-lifetime migration and all five previously failing CI suites
passed locally (167 tests). Same-token gateway A → B → A and six
broker/launcher boundary tests passed.
- Remote callback, launcher, sandbox, and runtime contract tests passed.
Both native and legacy Codex completed actual Daytona executions on the
integrated revision ([campaign
results](https://github.com/paperclipai/paperclip/actions/runs/34155056509)).
The remote package-manager shim staging regression also passed locally.

## Risks

- Deploy the migrations, server broker, launchers, and runner artifacts
together. Existing processes finish with their original contract. New
managed processes need the broker endpoint for GitHub operations.
- Finish or stop new managed executions before rolling application code
back. Keep the additive schema and identity history during rollback.
- Scripts that require a persistent raw GH_TOKEN must use managed git,
gh, or GitHub gateway tools. Run capabilities authorize code executing
within that run to acquire its current identity; this is not
hostile-code isolation within one execution principal. Managed commands
prevent automatic credential carryover; arbitrary code deliberately
copying a credential is outside that boundary.
- Uncertain steering acknowledgement deliberately holds new credential
acquisition until reconciliation. Already-started operations retain
their captured identity.
- GitHub private access and provider outages can still fail the specific
operation that needs them. Dedicated grant failure does not fall back to
personal access.

## Model Used

OpenAI GPT-6 through Codex assisted implementation, review, shell
execution, and browser acceptance. The exact model variant and
context-window size are not exposed in this session. Tool use included
TypeScript and Rust tests, database integration tests, GitHub CLI, and
authenticated browser control.

DottaandPaperclip 86ebdf842e fix(runner): keep agents running when app connections expire (#12670)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents can receive governed access to connected apps through the
runtime MCP gateway.
> - A connected app can become unavailable when its sign-in expires or
its health state needs attention.
> - The native runner treated that optional app state as a fatal runtime
setup error.
> - One unavailable app could therefore stop all unrelated agent work.
> - This pull request removes the fatal dependency and keeps the
available app assignment immutable.
> - The benefit is that an agent can continue its work while the stream
tells the user which app needs reconnection.

## Linked Issues or Issue Description

**What happened?**

An agent could not start a native run when one assigned app connection
was disabled, degraded, failed, or missing its secret. Runtime context
creation or MCP delivery threw an error before the agent could do
unrelated work.

**Expected behavior**

The run must continue without the unavailable app. Healthy assigned apps
must remain available. The stream must explain which app needs
reconnection. A changed assignment must not give a native run new access
after its immutable context is captured.

**Steps to reproduce**

1. Assign an MCP app connection to a Paperclip Runner agent.
2. Set the connection to a state that needs attention, such as
`degraded`.
3. Start a task run for that agent.
4. Observe that native runtime setup fails before the agent starts.

**Paperclip version or commit**

Reproduced from `ee2a19062`. The branch is rebased on `dda4dff64`.

**Deployment mode**

Local development from source with embedded Postgres.

No matching public issue or open pull request was found in the GitHub
search.

## What Changed

- Filter unavailable assigned app connections from the immutable native
runtime MCP snapshot.
- Keep healthy assigned connections and their tools in the snapshot.
- Replace the fatal native MCP availability check with an optional
stream warning callback.
- Withhold MCP delivery when the current assignment digest does not
match the captured native context.
- Prevent a warning delivery failure from stopping the agent run.
- Add regression tests for disabled, degraded, mixed healthy and
unavailable, and assignment-drift cases.

## Verification

- `pnpm exec vitest run
server/src/services/native-runtime/runtime-context.test.ts
server/src/__tests__/heartbeat-runtime-mcp-servers.test.ts` passes with
8 tests.
- `pnpm -r typecheck` passes.
- `pnpm check:token-gates` passes.
- `pnpm build` passes.
- `pnpm test:run` was attempted. Unrelated workspace runtime and
port-exposure tests failed on this macOS host. The same files also
failed when run without the changed MCP tests. The changed MCP tests
remained green. Clean GitHub CI is the final full-suite check.

## Risks

- Low migration risk. This change has no schema or API contract
migration.
- An unavailable app is absent from the run MCP surface until it is
reconnected and a later run captures it again.
- Assignment drift fails closed. The agent keeps running, but the
changed gateway is not delivered.
- This pull request does not auto-block the issue before the agent
decides that the app is required. It emits reconnect guidance in the
stream. The existing connection-request interaction remains the path for
a required app.

## Model Used

- OpenAI Codex, `gpt-5.6-sol`, with high reasoning, repository tools,
code execution, and browser automation. The runtime did not expose the
context-window size.

Dotta 131f5c4065 feat(runner): add administration and observability (#12641)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Administrators need bounded controls for experimental native
execution.
> - The lower stack adds remote Codex execution and the task workspace.
> - Operators need to configure Codex safely and inspect provider
traces.
> - Unsupported providers must not appear as runnable choices.
> - This pull request adds Codex-only administration and observability.
> - The benefit is a default-off operational surface for production
diagnosis.

## Linked Issues or Issue Description

Refs #12640.
Refs #12616.
Refs #12352.

**Subsystem affected**

Agent configuration, instance experimental settings, run ledger,
provider trace inspector, and administrator actions.

**Problem or motivation**

The native runner lacks one safe operator surface for Codex permissions,
lifecycle, raw trace capture, and run inspection. The integration branch
also contains provider choices that the production backend cannot
execute yet.

**Proposed solution**

Expose only the qualified Codex controls. Keep Paperclip Developer Mode
and runner preview ingress off by default. Gate raw trace actions by
administrator access and existing trace authorization.

**Alternatives considered**

Exposing unfinished providers would create configurations that fail at
runtime. Always-on tracing would increase sensitive data and storage
risk.

**Roadmap alignment**

This work supports governed Cloud and Sandbox agents and production
diagnostics.

## Stack

- Base PR: #12640.
- Lower PRs: #12639 and #12638.
- This PR contains only its 54-file administration and observability
delta.
- This is the final feature PR in the Codex production stack.

## What Changed

- Added Codex-only Paperclip Runner permission and lifecycle controls.
- Added bounded warm idle configuration.
- Kept the provider field fixed to Codex.
- Added administrator-only one-run raw trace requests.
- Added a persistent future-run raw trace toggle.
- Added trace status, metadata, ledger, and canonical runner inspection.
- Added JSON-RPC request-origin grouping and finalization lineage.
- Restored the stateful PRP transcript parser and focused projection
tests required by trace inspection.
- Added default-off Paperclip Developer Mode.
- Added Honeycomb run links for authorized developer mode.
- Disabled the legacy operational skill for `paperclip_runner`.
- Did not expose OpenCode, ACPX, Pi, Claude Managed, or AWS runner
choices.
- Did not change migrations, workflows, dependencies, or
`pnpm-lock.yaml`.

## Verification

- GitHub Actions will run UI tests, server tests, repository typecheck,
build, browser tests, security, and policy gates.
- Tests cover Codex configuration defaults and bounds, administrator
trace actions, persistent settings, ledger inspection, trace lineage,
and Honeycomb links.
- Existing server trace authorization and retention tests remain the
backend authority.
- Local tests were not run. The requested verification policy uses
GitHub Actions for this series.
- `git diff --check runner/task-workspace-experience...HEAD` passes.
- The delta contains 54 files.

## Risks

- Raw provider traces can contain sensitive provider data.
- Existing server authorization controls access, reveal, download,
retention, and deletion.
- The UI gates trace actions by administrator access and developer mode.
- All new instance settings remain off by default.
- Fresh Paperclip Runner configuration remains Codex-only.
- Direct adapters and legacy task behavior do not change in this PR.

first. See `CONTRIBUTING.md`.

## Model Used

OpenAI Codex with GPT-5.6. The work used high-reasoning agent mode,
repository tools, GitHub tools, and parallel code-audit agents.

DottaandDev Agent 25cf079ec5 feat(runner): add Codex-native application integration (#12591)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runner package is useful only when the application can start,
observe, and recover a native Codex run safely.
> - Existing direct adapters must keep their current execution and
finalization paths.
> - The application boundary therefore needs additive persistence,
authorization, coordination, and recovery behind an explicit
experimental adapter.
> - This pull request adds that Codex-only boundary without activating
generalized providers, remote environments, or the later task/SDK
surfaces.

## Linked Issues or Issue Description

**Subsystem affected**

Shared contracts, database persistence, adapter utilities, server
native-runtime services, and the experimental Paperclip Runner adapter.

**Problem or motivation**

The already-landed runner package has a qualified Codex path, but the
application needs durable native-run state, guarded runtime selection,
authenticated coordination, tool security, finalization, and recovery
before the experimental adapter can be exercised safely.

**Proposed solution**

Add a Codex-only `paperclip_runner` application path behind the existing
default-off native-runner setting. Bind native state and coordination to
company/run identity, preserve persisted-run recovery, and leave every
direct adapter on its existing legacy execution path.

**Alternatives considered**

The earlier stack boundary introduced a generalized executor and
remote-environment lifecycle here. That made this PR depend on
implementations in higher PRs and changed reusable sandbox behavior
globally. Those pieces are now deferred together to #12592.

**Roadmap alignment**

ROADMAP.md does not list a conflicting native-runner integration
project. This change adds the application boundary for the existing
Runner architecture.

## What Changed

- Added native run/result/finalization/provider-trace persistence,
shared validators, and idempotent migration/replay coverage.
- Added guarded Codex-only runtime selection, authenticated PRP
coordination, recovery, finalization, and interaction services.
- Added run/company-bound tool-gateway authorization, credential
redaction, SSRF protections, and replay-safe behavior.
- Added the explicit `paperclip_runner` adapter behind the default-off
rollout setting.
- Preserved legacy answered-question wake projection and direct-adapter
execution/finalization paths.
- Hardened cancellation so only owned in-memory child processes are
signaled; persisted recycled PIDs/process groups are never trusted.
- Retained the narrow Claude ACPX isolated-context security follow-up
discovered after #12590.
- Deferred the generalized executor, provider ingress, remote lifecycle,
SDK/lab/eval work, release-process changes, and lockfile.

## Verification

- Changed-file delta against `master`: 133 files.
- GitHub Actions is the authoritative verification environment for this
PR.
- Full CI, security, and Greptile review will run on this lowest
unmerged stack PR.
- Local tests/build/typecheck were not run because this checkout is
resource constrained.
- Static diff/reference checks pass, and `pnpm-lock.yaml` is unchanged.

## Risks

- This touches central heartbeat and agent-route code, so legacy
compatibility is the primary risk.
- Runtime selection remains Codex-only and explicit; direct Codex,
Claude, OpenCode, process, HTTP, and plugin adapters remain on their
existing paths.
- Fresh native starts fail closed while the rollout flag is off;
persisted native records remain readable and recoverable.
- Cancellation, company/run binding, tool calls, status decisions, and
completion writes are guarded or replay-safe.

> 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.
