DottaandPaperclip 6987c2f20b test(upgrades): qualify controller replacement with immutable artifacts and phase evidence (#17455)
<!-- entire-trail-link-start -->
https://entire.com/gh/paperclipai/-/trails/105/changes/paperclip/105
<!-- entire-trail-link-end -->

## Thinking Path

> - Paperclip needs evidence that an admitted execution survives a
main-server replacement.
> - Runner mechanics and server adoption belong to #17097 and #17439.
> - A healthy HTTP endpoint does not prove recovery of the original
execution.
> - Qualification must identify the serving artifact, natural ownership,
authenticated attachment and resumed processing separately.
> - It must also retain failed runs and measure normal-operation costs.
> - This PR extends the existing qualification machinery and acceptance
record.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Operators can assess upgrade continuity from phase evidence tied to
exact artifacts and profiles.

**Current behavior**

A same-artifact restart or synthetic executor pass cannot establish
different-artifact upgrade and rollback support. Idle SQL gates also do
not measure active-run capacity.

**Proposed behavior**

Use immutable A/B artifacts and strict phase receipts through the
existing supervisor. Preserve failed evidence and add measured
before/after workload costs.

Builds on merged #17097 and #17439. The base is now `master`. #17456
follows for review convenience. This PR lands qualification machinery
and the evidence record. The remaining hosted gates stay open for
deployment qualification; merging this machinery does not claim those
experiments passed.

## What Changed

- Extend the main-server supervisor and installed-artifact verification
for actual serving revisions, forward migrations and compatible
rollback.
- Distinguish HTTP readiness, natural ownership, authenticated
attachment, resumed processing and backlog settlement.
- Retain the original reconnect grace and execution identity checks.
Never substitute a new task or edited lease for continuity.
- Reuse real-harness and Daytona qualification paths, with exact profile
and artifact provenance.
- Bind current Copilot attestation inputs in the Daytona image
fingerprint.
- Keep one acceptance record, including both failed file-only stress
phases and the final passing bounded-pool comparison.

## Verification

After retargeting to master, all 158 focused qualification cases across
13 files pass, with E2E typecheck. The first 12-file batch has four
report-lock test failures and 133 passes. Master #17811 had committed
the exact already-approved output lock, while that fixture assumed HEAD
must be the uncorrected input. The fixture now checks both pinned forms,
executes the committed-lock path, and reconstructs the pinned input to
retain all rejection tests. The production helper, policy hashes, patch
and dependency resolution are unchanged. The corrected batch explicitly
includes both process-preservation suites; the prior 146-case receipt
has its own source and selection.

Current candidate `8f1d6ec02f` integrates master `09ad9adce2`, including
the merged server slice. Its diff contains only qualification code and
documentation. The [qualification
record](https://github.com/paperclipai/paperclip/blob/8f1d6ec02f5bf6c90e7b27da8156953cabd9a180/doc/plans/2026-10-22-hot-upgrade-qualification.md)
is the acceptance ledger and retains source-attributed failures and
hosted limits.

On the eighth integration, all 146 cases across 12 focused qualification
files pass, including report-lock preparation, workflow security and
workflow targeting. E2E typecheck passes. The earlier 118-case result
remains attributed to its prior source. The first sandbox invocation has
117 passes and one failure because process inspection was denied during
inert fixture cleanup. The permitted repeat passes all 118 and a
targeted process check finds no remaining fixture daemon. The earlier
96-case receipt remains source-attributed in the ledger. The latest two
review regressions first fail: an intermediate replacement can cite
another runner/session despite a valid final step, and malformed receipt
JSON aborts evidence packaging. Each replacement now binds
run/company/issue/runner/session, and corrupt receipts retain explicit
invalid metadata plus sanitized diagnostics while other logs and
receipts still package. These checks prove qualification machinery with
injected supervisor operations, configuration subprocesses and real
filesystem packaging. They do not qualify a hosted harness.

Three request-reader cases, 14 artifact/configuration/cache/history
cases, and three lost-partial-receipt cases fail before their respective
corrections. The final collector preserves sanitized startup, readiness
and recovery phase receipts through packaging and temporary-root
deletion. Earlier embedded-Postgres initialization, report-catalog
drift, CI scheduling/cleanup failures and fixture collisions remain
recorded with their corrections or limits. The previous Greptile service
error is retained as historical review evidence, not a current review
pass.

The record includes prior source `9bb9d3417e`'s actual Linux
contention/fairness successes and the ordinary-warm regression proof
from the server slice. The historical 300-session component campaign
passes four after phases and retains earlier burst failures. Those
component costs do not establish hosted capacity. The hosted API-only
pair has zero agents/viewers, fails both absolute latency gates and the
candidate memory gate, and does not complete the active-agent/viewer
matrix.

The strict ten-agent same-artifact restart remains attributed to its
original artifact. It does not qualify this updated stack. Actual
A→B/B→A, the normal drain-free Cloud rollout, and other hosted harnesses
remain open. No new provider turn, deployment or hosted qualification
was run during merge preparation.

Prior source `57d3767eac` jobs 122590643944, 122590643983 and
122590644161 ended after runner shutdown/cancellation without final
Vitest results. The shutdown cause is unproven. No retry was issued
before this source was superseded by the required server recovery fix.
These attempts remain failures/incomplete evidence. Fresh exact-head CI,
legacy status, completed Greptile 5/5, resolved feedback and normal
merge eligibility remain required.

## Risks

Different-artifact A→B/B→A, the normal drain-free Cloud rollout path,
other hosted harnesses and the complete concurrency/viewer matrix remain
open. Frozen branch builds are development-build evidence. This PR owns
qualification and evidence; production defects must be fixed in their
earlier owning slice.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools and code
execution. The runtime does not expose a more specific model ID or
context-window size.

# Everyday Paperclip workflow evals
## Main-server outage qualification
The remote native Codex and Claude `recover-controller` cells default to SIGKILL,
an observed 125-second offline interval and retirement of the old controller cache. They use
natural ownership timing. The wrapper emits `controller-outage.json`; the grader
requires distinct server processes, confirmed HTTP loss, cache retirement and the
requested interval, in addition to same-run/provider-turn and finalization proof.
Partial fault receipts remain in the attempt's private `control/` directory on
failure. A successful task without the fault receipt cannot qualify.
Use `PAPERCLIP_RUNNER_E2E_CONTROLLER_STOP_SIGNAL=SIGTERM` for graceful shutdown,
`PAPERCLIP_RUNNER_E2E_CONTROLLER_OUTAGE_MS=1000` for an explicit one-second
experiment, or `PAPERCLIP_RUNNER_E2E_CONTROLLER_OUTAGE_MS=300000` for the
five-minute contract. These settings are recorded; compare only matching configurations. The configured
duration is a minimum hold after confirmed HTTP loss. Shutdown and startup add
to total recovery time; they do not extend the runner's seven-minute grace or the
workflow's attempt deadline. `recover-controller` permits no automatic retries.
```sh
PAPERCLIP_RUNNER_E2E_CONTROLLER_OUTAGE_MS=300000 pnpm test:e2e:runner -- --id everyday-workflows.runner-codex.daytona.recover-controller --max-automatic-retries 0
```
The credential-free wrapper smoke starts the actual main server and a separate
disposable Postgres, kills/replaces the server, checks that Postgres never
restarted, reads existing data, accepts a new HTTP mutation, and confirms cleanup:
```sh
node cli/node_modules/tsx/dist/cli.mjs tests/runner-e2e/controller-replacement-smoke.ts
```
It prints a private JSON evidence path. It uses no model and **does not qualify
active-agent continuity, queued launches, or an A-to-B version upgrade**. See the
[qualification plan](../../doc/plans/2026-10-22-hot-upgrade-qualification.md) for the
separate gates and outstanding work. Hosted qualification still requires a valid
pinned Daytona image and the existing credential/budget admission.
## Workflow suite
This manual suite tests useful work through the production browser, public API,
native runner, and normal agent instructions. It complements the tightly
scripted runner contract fixtures. It does not add a scheduled or default paid
run: `--all` and generic profile selectors exclude it. Select the suite or an
exact execution ID explicitly.
## Stories and assertions
| Story | Cases | Required evidence |
|---|---|---|
| Build a small project and revise it | `build-revise` | Download both ZIPs through the UI; independently execute the delivered CLI and import its function; test the revision; retrieve the original bytes again. |
| Delegate and incorporate late feedback | `delegate-feedback` | One child assigned to Riley; send feedback while the child runs; find it in the child history and independently test `--max-length` in the delivered ZIP. The worker must not execute on the parent. |
| Hire a teammate and use them again | `hire-reuse` | One Morgan QA reporting to the lead, native runner and the same encrypted connection bindings, real child execution, then a second usable delivery from that same agent. |
| Decide on an installed service action | `service-approve`, `service-decline` | Assign an authenticated local MCP fixture with Ask first; match its tool action and connection ID; no provider call before approval; exactly one after approval and a verified document; none after decline. |
| Decline a new connection | `connection-decline` | Start without service connections; match a Notion connection intent; click Not now; verify the saved rejection, no new connection or repeated request, and an explanation followed by Done. |
| Request an email address | `agentmail-setup` | Enable Chat connectors, ask for an email address, and require a durable AgentMail card for the requesting agent and user. Reload and verify one password field, the direct API-key link, and no access selectors or modal. Decline and verify no connection or repeated request. |
| Continue work after a controller restart | `recover-controller` | Observe saved source, persist a user message, restart the isolated controller, and independently test the delivered result. Native Daytona cases keep the controller offline for 125 seconds before restarting. |
| Stop work and change direction | `stop-redirect` | Click Stop, send one new request, reload, observe exactly one stored user message and the new answer, and reach Done. |
| Create and edit a company skill | `create-skill-studio` | Create one skill through the runner, verify its persisted library entry and activity-feed card, open Skill Studio, save an edit, and verify the edit after returning. Local Codex, local ACPX Claude, and warm Daytona cells are explicit. |
For normal completion, all story tasks must reach Done, with no active run,
pending completion confirmation, or scheduled recovery. Runs must prove native
identity and native terminal contracts. A workspace-contention cancellation is
not provider execution only when the persisted pre-dispatch record explicitly
says `providerWorkStarted: false` and no process/session/runner identity exists.
Other unexplained cancellations remain failures. Twelve total run records bound
each story, including contention and recovery.
Arbitrary runner-process termination is not part of the model scorecard. The
historical `recover-runner`, `recover-runner-safe`, and `recover-runner-uncertain`
attempts remain available as diagnostics, with their original grades and costs.
The first two did not establish a safe restart boundary, and the uncertainty
case measures a deterministic safety rule. None supports ranking models.
See [controlled recovery tests](../runner-recovery/README.md).
## Matrix and running
The local matrix has fourteen cases on native Codex `gpt-5.6-sol`, native ACPX Claude
`claude-sonnet-5`, and native Codex `gpt-5.4-mini`: 42 cells. The two core profiles
also declare build/revise, delegation, controller-restart, and skill-creation cases
on Daytona: eight cells. OpenCode adds only local hiring/reuse and delegation,
for 52 cells total. Hiring/reuse and delegation have one attempt and a
1,000-cent company and lead-agent hard stop. Remote runner-process killing is not supported. For remote controller
restart, a verified first download supplies the persistence checkpoint; the
controller is interrupted during a subsequent revision with another queued
requirement.
The native Codex and ACPX Daytona restart cells require a completed native tool
receipt while that revision is still running. They keep the controller offline
for 125 seconds after its health listener stops, then start its replacement.
Before and after restart each pins
the same run, normalized session, Runner identity, PID/start time, and active
sandbox lease. The original receipt prefix must remain unchanged. A run that
uses this native Codex remote cell also loses the old controller runtime cache
between stopping and starting the server. The harness moves it into private
evidence outside product lookup paths and requires an acknowledgement of that
fault. Postgres and the instance encryption key survive. This checks deployment
recovery without relying on the old controller journal or local warm-session cache.
A run that
ends before either active observation leaves the fault boundary unexercised;
it cannot pass from the final ZIP alone. The cell no longer exempts an original
Codex remote run that fails with `process_lost` and is replaced.
Completion requires one original provider turn and control-plane terminal,
the same native receipt prefix, no failed native tool receipts, and consistent
results for every stable completed tool identity. Reattached activity can
redeliver an identical start or tool receipt; changed content or a second
submission fails. It also requires
a committed run and successful `workspace_finalize` receipt, and no pending
workspace operation or recovery. Existing independent ZIP and preserved-download
checks still apply. These receipt checks do not prove that arbitrary external
effects with different tool IDs cannot repeat.
`remote-restart-before.json`, `remote-restart-after.json` and
`remote-restart-final.json` retain receipt identities and hashes. They exclude
provider text, tool arguments, command output, and raw provider sandbox IDs.
The suite definition version and harness digest change with this oracle.
Its deterministic calibration is not a claim that a live Daytona run passed.
```sh
pnpm test:e2e:runner -- --id everyday-workflows.runner-codex.daytona.recover-controller --max-automatic-retries 0
```
```sh
pnpm test:e2e:runner -- --list --suite everyday-workflows
pnpm test:e2e:runner -- --suite everyday-workflows --environment local --max-parallel 2
pnpm test:e2e:runner -- --id everyday-workflows.runner-codex-mini.local.build-revise
pnpm test:e2e:runner -- --suite everyday-workflows --environment daytona --max-parallel 2
```
Before project stories or the Python calibration tests, start Docker on the
harness host and fetch the pinned oracle image. CI prepares and verifies this
same pinned image before the paid project-story cells; artifact checks run on
the harness host. The workflow verifies the exact repository digest after the
pull. This is required for local and Daytona stories.
```sh
docker pull python@sha256:9d2e5553305c7c7b0097999bb17187c69b921ccd6bc9d40e4bb5ebe652c00285
python3 tests/runner-e2e/everyday-artifact.py --preflight
```
The harness checks this prerequisite before it creates the task. It does not
pull an image during a model attempt or fall back to host execution.
Use the credential and immutable Daytona image setup in [README.md](README.md).
Provider calls cost money. Each cell owns an isolated instance and project.
There are no real third-party mutations in the service fixture; it exercises
production connection, transport, tool approval, and document delivery paths.
## Deterministic checks and calibration
```sh
pnpm test:e2e:runner:typecheck
pnpm test:e2e:runner:unit
python3 -m unittest discover -s tests/runner-e2e -p test_everyday_artifact.py
```
The independent oracle rejects wrong output, ignored late feedback, trailing
separator bugs, invalid argument acceptance, duplicate source modules, archive
path traversal, and symlinks. Passing agent-authored tests cannot override it.
Lifecycle calibration rejects legacy execution, missing runner identity,
unexpected crashes, workers on the parent, and answers left in review.
ZIP evaluation runs delivered Python in a Docker container with a read-only
project mount and root filesystem, no network, a non-root user, no Linux
capabilities, and bounded CPU, memory, process count, output, and duration. Only
the extracted delivery enters the container. The container is removed after
grading. Calibration includes attempts to read a host file and reach a host
loopback service.
## Evalbook evidence and qualification
Each packaged attempt retains `snapshots/everyday-workflow.json`, downloaded
ZIPs, assertions, actual task comments and run records, timing, accounting,
source provenance, and screenshots. The story records a digest of its harness
sources. Infrastructure failures and failed attempts must remain inspectable.
Import packaged results with `paperclip-evals/evals/everyday-workflows/import_results.py`.
It uses the canonical Runner Evalbook generator and the built Runner Lab viewer.
It does not invent provider transcripts, tool counts, model observations, or
cost estimates. The selected model is checked against persisted native execution
inputs; that is distinct from provider-side model identity verification.
Initial live results are diagnostic. They are not a reliability estimate or a
model ranking. Before promotion, freeze both source revisions and harness
digest, run at least three independent local repetitions, qualify the eight
remote cells against a verified image, and review every failure. Keep model
quality, lifecycle correctness, infrastructure availability, and latency separate.
## Revised evaluation contract (14 September, second campaign)
That campaign used 32 cells: the original local stories plus two local Codex
text-only safe-replacement probes, and the unchanged six remote cells. The old
`recover-runner` results remain historical; `recover-runner-uncertain` is a new
case that expects a visible Blocked safety stop, preserved source and queued
input, and no unverified provider replay. Its Retry control is inspected, not
claimed to restore work. Successful manual recovery remains unqualified.
`recover-runner-safe` interrupts a text-only Codex turn and queues new direction.
A pass requires the server's durable `verified_safe_replacement` evidence and the
new answer. No safety proof is injected or fabricated. If that premise cannot be
verified in a live probe, report it as an unqualified recovery boundary, not an
established product defect. Claude has no catalog cell for this Codex-specific
replacement proof. Deterministic native-safe-replacement tests cover its proof
and admission gates independently of model behavior.
Delegation now submits feedback through the existing child task composer and
records the delivered comment ID. The child must consume the message and deliver
the revised program. This does not require a lead to relay a parent comment.
The separate issue-update-comment-wakeup route tests exercise exact supported
mention routing, including access, dependency, identity, and duplicate-wake gates.
The approval case provisions an authenticated local service through the public
API, with a random server-held credential that never enters the agent environment
or browser trace. Approval/decline interactions still use the browser. Provider
captures distinguish rejected unauthenticated requests from accepted calls. The
old public-endpoint attempts remain boundary evidence, not an isolation promise.
Stop now waits for the owned runner to exit, records project file hashes, and
checks them again after the new response. This proves stability over that interval,
not indefinite monitoring. Hiring and declined-access policy changes are deferred
by user decision; their old results must not be presented as new campaign runs.
## Decline correction (14 September, third campaign)
That campaign used 35 cells (29 local, six remote). `service-decline` tests
rejection of a protected action on an already installed service; its former
"connection request" title was misleading. `connection-decline` separately tests
Not now on new Notion setup. Both permit a brief explanation as the complete
fallback, so Done is expected after that explanation. Neither test requires
completion after refusing work that is still required.
The installed-service decline fixture now uses the same server-held credential
as approval. The harness requires one pending interaction, validates its kind
and connection/provider identity before clicking, and waits for the exact
interaction's saved decision. Wrong interactions fail `decision-request-matches-story`
with a screenshot; they are not evidence of an ignored decline. Both decline
stories check a new explanation after the decision and reject repeated requests.
Historical attempts remain unchanged. This campaign resumes the previously
deferred decline cases; hiring remains deferred. Notion setup is declined in
the UI, so this test neither authenticates to nor reads real Notion data.
Decision screenshots are included in the evidence package. Before capturing the
final screen, the harness waits for the thread and latest persisted agent comment
to render, then scrolls that comment into view. A Done header alone is not proof
that the final response was visible.
## Recovery scope correction (14 September)
This correction reduced the catalog to **30 cells: 24 local and six remote**. Forced runner
crash probes are retired from paid selection. Their original attempt IDs remain
in Evalbook's Diagnostics history and Latest pages; they are excluded from the
main matrix without changing grades or deleting evidence. Reported spend still
includes all attempts.
`recover-controller` and `stop-redirect` retain concrete supported journeys:
restart the controller while preserving the runner, or use Stop and submit a new
direction. Their assertions verify pending input, saved work, and the next
usable result. Neither claims recovery from an arbitrary provider-process crash.
A future user-facing crash-recovery case needs a reproducible recoverable fault,
an identified supported recovery action, and evidence through the final usable
result. A missing test premise must be reported as unexercised, not a model
failure. Do not introduce a new paid case just to replace a retired row.
## Skill creation (16 September)
`create-skill-studio` adds five cells: three local profiles and the two core
profiles on Daytona. The current catalog has **35 cells: 27 local and eight
remote**. The test opens the created skill from its task-feed card, checks the
canonical skill identity in Studio, saves an edit, and returns to the same skill
in the task sidebar. A model's authored document heading is not used as the
identity check.
## External-provider fallback
Three explicit local cases cover aggregator routing with the normal production
agent guidance. They add nine local cells. The AgentMail setup case adds three
local cells; the suite now has 50 cells total.
The AgentMail case uses real model discovery and production interaction/UI paths,
but declines before sending credentials to AgentMail. Its independent grader is
calibrated against missing, duplicate, misaddressed, hidden, and malformed cards.
The email integration suite separately proves credential/inbox creation, access
defaults, assignment checks, and completion using a fixture provider. Neither
test qualifies live AgentMail delivery. Run a bounded local model cell with:
```sh
pnpm test:e2e:runner -- --id everyday-workflows.runner-codex-mini.local.agentmail-setup --max-automatic-retries 0
```
- `provider-native`: Jira is supported natively and by aggregators. Require the
Jira connection card directly, decline it in the browser, and verify no provider
question, connection creation, or repeated request.
- `provider-decline`: HubSpot has no built-in connector in this fixture. Require
Composio, Arcade, Zapier, and None in that order with external-service disclosure.
Restart the controller, reload the question, choose None through the UI, and
verify one saved answer, no connection changes, and no fabricated result.
- `provider-second`: Install a deterministic Arcade gateway with a read-only
HubSpot action through public APIs. Choose Arcade in the browser after restart.
Require no calls before selection, exactly one call afterwards, the independently
generated contact marker in the agent response, and no duplicate connection.
These use the existing native profiles and 12-minute local attempt deadline;
expected provider runs are two per case. There are no real third-party mutations.
The fixture server is closed and the harness cleans its disposable instance.
Provider-choice screenshots, persisted interactions, gateway call counts, source
revision, harness digest, and existing usage/cost evidence accompany each attempt.
`connection-routing-evidence.test.ts` calibrates the grader against undisclosed
routing, incorrect ordering, early calls, duplicate questions, and fabricated reads.
Run a single `everyday-workflows.runner-codex-mini.local.provider-decline` cell
first; do not treat these fixtures as live provider compatibility tests.
### Connection-guidance observation boundaries
The explicit `native-connection-guidance` suite keeps one attempt per cell.
For decline cases, Done and a succeeded run are insufficient: settlement waits
within the existing cell deadline for a saved reply attributed by run ID to the
lead agent's final successful run on this task. Readiness checks storage and
identity, not favorable wording. A missing reply times out; an incorrect reply
settles and fails the independent explanation check. Both decline explanation
checks use the same bounded matcher, including unavailable/rejected access and
“wasn't able to pull” wording. This is textual evidence, not proof of cognition.
An executed approval or a recorded tool-action rejection with `wake_assignee`
may precede its continuation run. Only a response bound to the same task, company,
agent, and completed source run can defer the stranded-blocker check, and only
within the original deadline. A failed execution, unrelated card, or already
consumed response cannot extend that wait.
`connection-guidance-decline-grade.json` and the workflow's
`declineGradeEvidence` retain the exact cloned assertion input and original
checks. Later final-state or cleanup observations cannot overwrite that input.
Earlier campaign grades remain unchanged when the evaluator is corrected.
# Upgrade qualification receipts
`PAPERCLIP_RUNNER_E2E_UPGRADE_ARTIFACTS` selects frozen installed A/B artifacts
and an alternating A/B/A sequence. The remote controller-recovery workflow
executes every requested replacement on the original active run. If that run
ends before a later fault can be injected, that boundary is unexercised; starting
a replacement task does not qualify it.
The supervisor reads existing Postgres ownership and Runner-owned checkpoint
evidence. It records HTTP readiness, natural lease takeover, a new authenticated
connection, and ingestion past the stopped controller's saved event cursor.
Final native and workspace receipts establish backlog settlement. No lease
timestamps are edited. Authentication and processing must be observed within
the original 420-second grace, including artifact verification and startup.
For a credential-free startup/migration experiment, run
`controller-replacement-smoke.ts` with the manifest and an explicit disposable
`PAPERCLIP_TEST_DATABASE_URL`. The driver creates and drops a unique empty
database; it does not change the supplied database. This smoke qualifies zero
agent turns. The [qualification record](../../doc/plans/2026-10-22-hot-upgrade-qualification.md)
is the acceptance ledger for exact artifacts, attempts, and remaining gates.
