DottaandPaperclip 3b84c89885 fix(ci): use complete merge diffs and allow audited documentation (#18362)
## Thinking Path

> - Paperclip manages AI agents and needs reliable checks for each
contribution.
> - CI selects affected suites and then affected Vitest files before
allocating runners.
> - Recent runs compared a tested merge against a stale event base.
> - That included unrelated master changes and sometimes reached the
compare API file cap.
> - Ordinary documentation also forced every suite and invalidated test
caches.
> - This PR reads complete merge trees and exempts a small set of
audited prose inputs.
> - Tests retain conservative coverage when the diff or an input is
uncertain.

## Linked Issues or Issue Description

Refs #18348 and #18214. This is a follow-up to the merged affected-test
selector.
Related CI performance work: #16513 and #16500 address setup and suite
execution. This PR changes diff collection and input classification.

## What Changed

- Fetch the exact tested merge and its parents into a temporary bare
repository. Read the complete tree diff against the actual first parent.
Validate the second parent against the event PR head. Never execute PR
code in the routing job.
- Carry the immutable base, merge and PR-head identities into the plan.
Validate the same complete diff again before file selection.
- Use one prose policy across the planner, Vitest selector and task
cache adapter. Exempt only `doc/DEVELOPING.md`, `doc/DATABASE.md`, and
Markdown under `doc/plans/`.
- Keep the uncached typecheck and CLI guidance guard for the first two
documents. Keep policy checks for historical plans. Keep existing
coverage for all other docs, runtime skills, fixtures and unknown
inputs.
- Extend candidate-workflow qualification to exercise mixed source and
prose changes.

## Verification

- Passed: 15 planner and Git routing tests, including a 353-file diff,
stale base, rename, deletion, wrong parent and fetch-failure cases.
- Passed: 83 routing, Vitest graph, exact selection, workflow and real
Turbo cache checks.
- Passed: `pnpm -r typecheck` and `pnpm build`.
- Full local `pnpm test:run` was attempted and stopped after repeated
embedded PostgreSQL startup failures in native-session and Muse tests.
It did not pass or complete. The exact cause remains unverified. The
changed files do not include those tests or their database setup. Linux
CI results are recorded below.
- Passed: real mixed Inbox/source/prose graph qualification selected
699/911 workspace test files, preserving the source-only selection.
- Passed: both GitHub CI qualification jobs, including real mixed
source/prose Vitest selection. Greptile reviewed commit `10ac6f5ec9` at
5/5 with no findings.
- First full CI attempt: the [chat
shard](https://github.com/paperclipai/paperclip/actions/runs/41111003419/job/124253342684)
received a runner shutdown signal. The [Runner
shard](https://github.com/paperclipai/paperclip/actions/runs/41111003419/job/124253341271)
failed the unchanged Antigravity authentication success assertion. All
11 cases in that file passed when run directly. That Runner lane does
not use the changed selector/cache path. The exact assertion-failure
cause remains unverified. The chat shard passed on the one retry. The
authentication assertion also passed on retry, but the same Runner shard
failed a different unchanged test:
`native-distribution-integrity.test.ts:242`, "retains spawned native
bytes until the exact child exits", exceeded 5000ms. The [retry
log](https://github.com/paperclipai/paperclip/actions/runs/41111003419/job/124259174201)
preserves the failure. The Runner shard and required verify aggregate
are still red; all other checks passed. All 33 native-distribution tests
then passed in a direct local run. This shows recovery in isolation, not
the cause of the Linux timeout. No further blind reruns were issued.
- Replayed 15 real recent PR merge commits through a blob-filtered bare
fetch. Nine needed a corrected base. The four API comparisons that
returned 300 filenames became complete diffs of 3, 57, 66 and 54 files.
The 3-file case (#18326) becomes eligible for graph selection. Most
other samples still correctly use full CI because they include inputs
outside this narrow prose policy.
- Cache proof: prose edits preserve a product-test cache hit; changing
runtime API documentation invalidates it.

## Risks

- Prose exceptions must be removed or revised if product code starts
reading those files. The allowlist is deliberately small. Runtime docs
and skills remain covered.
- A network or Git failure keeps the full-suite fallback. Unexpected
merge topology also keeps full CI. Stack and force-full policies remain
in place.
- This does not claim an end-to-end speedup yet. Many mixed-content PRs
still require full CI. The routing fetch reads only shallow commit/tree
objects; it does not check out or execute PR files.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, repository tools and code
execution. The exact served model ID and context-window size are not
exposed to this session.

DottaandPaperclip f5dcc505c0 perf(ci): select affected suites and cache task results (#18214)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Pull request CI checks the server, UI, packages, Runner, and release
paths.
> - An ordinary PR starts 48 jobs even when its diff affects only a
small part of the repository.
> - Repeated pushes also repeat successful tests with unchanged inputs.
> - This PR selects affected suites before runner allocation and caches
deterministic task results with Turbo.
> - Required checks validate the plan. Unknown inputs and failed
comparisons keep full verification.
> - The benefit is fewer runner jobs and less repeated work, with full
post-merge verification retained.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

The GitHub Actions PR workflow repeats unrelated suites for each push.

**Subsystem affected**

Cross-cutting CI routing, test execution, and required-check
aggregation.

**Current behavior**

An ordinary UI component change starts the complete 48-job PR workflow.
Existing dependency and compiler caches do not reuse successful test
results.

**Proposed behavior**

A trusted planner reads the tested merge diff and task inputs. A UI
component change such as `ui/src/components/Sidebar.tsx` selects 18
jobs, including build and browser coverage. Successful general,
serialized, and standalone Rust tasks can reuse unchanged results across
pushes in the same PR.

**Reason and benefit**

Reduce unrelated jobs and repeated test execution. The 48-to-18
comparison measures planned job count. Remote wall-clock savings have
not yet been measured.

**Breaking changes**

No application API changes. Required `verify` and `e2e` names remain
stable. `verify` also checks serialized suites and the canary dry run.

## What Changed

- Added explicit task inputs and a pinned Turbo version. An execution
adapter calls existing package scripts without adding script aliases.
- Added trusted diff planning and dynamic matrices with complete
fallback matrices.
- Added PR-scoped task result caches. External-state and
revision-stamped checks remain uncached.
- Added and created the `full-ci` override label, plus repository modes
`enabled`, `shadow`, and `full`. Forced and shadow runs bypass result
caches.
- Added candidate-workflow qualification, planner and aggregate tests,
and a real Turbo cache fixture.
- Kept the repository-wide CLI guidance guard in the uncached typecheck
lane so UI-only diffs retain this security check.
- Documented rollout controls, input maintenance, and local inspection
commands.

## Verification

- Passed 537 focused CI policy, routing, matrix, cache, and shard tests,
plus 146 existing release workflow tests.
- Passed actionlint for all four changed or added workflows and `git
diff --check`.
- Passed `pnpm -r typecheck` and `pnpm build` on the implementation
base.
- Checked real repository task plans for existing general-test and
native Rust commands. A real server partition passed, then restored from
cache: Turbo task time was 20.022 seconds for execution and 151 ms for
the cache hit, excluding wrapper/setup overhead.
- The real Turbo fixture exercises the execution adapter and proves
source, argument, toolchain-scope, and environment invalidation, result
restoration, and retry of failed tasks.
- Stopped the serial local `pnpm test:run` after over 30 minutes in
favor of the complete parallel GitHub suite. A local parallel
database-lane attempt had PostgreSQL startup errors and timeouts. The
direct migration fixture passed, then all 273 database tests passed with
one local worker. This recovery does not establish the exact cause of
the earlier startup failures. The full GitHub PR suite and candidate
qualification passed on commit
`0bf07ae071c9fe7903edc604d44b5a175727fed0`. Greptile is 5/5 with no
unresolved review threads.
- All 40 CLI guidance safety tests passed with the exact uncached
workflow command.
- Verified that master rulesets require only `ci / verify` and `ci /
e2e`; both names remain unchanged.
- Trusted workflows load from master. The added GitHub-hosted
qualification workflow exercises this candidate planner before merge.

## Risks

- Changes to global inputs, including task definitions and execution
helpers, force execution and disable cache restore/save for the full PR
diff. Missing a cross-package filesystem read could omit a suite. Inputs
include known server reads of UI files and shared tests of UI assets.
Unknown paths, malformed or truncated diffs, and definition download
failures select all suites.
- Task result reuse requires complete inputs. Keys include Git source
files, scripts, resolved dependencies, environment, toolchain, checkout
path, and unclassified source files. Generated build artifacts are
excluded from input hashes. Registry smoke, browser, and
revision-stamped tasks remain uncached.
- Maintainers must update task inputs when suites start reading new
paths. `shadow` reports selection while running all work. `full` and
`full-ci` disable selection and result reuse.
- The implementation becomes active after merge. Full post-merge
verification remains unchanged.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, repository inspection, tool
use, and code execution. The session does not expose a verifiable exact
runtime model ID or context-window size.
