DottaandPaperclip 556b249897 fix: preserve exact Markdown in native document writes (#20605)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents save Markdown documents through native tools and REST routes.
> - The native write_document handler trims the supplied body.
> - This removes final newlines and can change Markdown whitespace.
> - This pull request preserves the original body after required-content
validation.
> - Agents can now write and read the same Markdown string across these
paths.

## Linked Issues or Issue Description

**What happened?**

The native write_document tool removes leading and trailing whitespace.
A body with one final newline loses that newline on read-back. The REST
document PUT and write_task_document preserve it.

**Expected behavior**

The native write_document tool must preserve the supplied Markdown body
exactly. Required-content checks and key and title normalization must
stay in place. REST-backed paths retain surrounding whitespace and keep
their existing escaped-line-break conversion for single-line payloads.

**Steps to reproduce**

1. Write a disposable document through write_document with a final
newline.
2. Read the document and compare the full body with the supplied string.
3. Repeat through write_task_document and REST. These paths preserve the
string.

Related work: Refs #18824. That change aligns document keys. This change
preserves body strings. A search of open and closed PRs found no
duplicate fix.

## What Changed

- Use a separate untrimmed required-string helper for the document body.
Keep the existing requiredString callback signature and all other field
normalization.
- Add real tool-handler, database, and authenticated HTTP tests for
create, update, read-back, and replay. Cover leading spaces, hard
breaks, blank lines, final newlines, no final newline, Unicode, and
mixed line endings.
- Keep blank and invalid bodies rejected. Document whitespace
preservation and the existing REST escaped-line-break exception.
- Fix the Runner support archive-scanner shutdown defect exposed by CI:
rejected ZIP scanners now receive SIGKILL so an ignored SIGTERM cannot
leave publication waiting for process closure. Keep all secret and
archive limits unchanged. A real child-process regression fails before
the change and passes afterward.
- Address all three initial review findings: callback type
compatibility, contribution comment policy, and the REST documentation
limit.

## Verification

Final tested head: `c9ff8cf3f83aa19e5d8313c65816a3a2e6562368`.

- All applicable [CI
checks](https://github.com/paperclipai/paperclip/actions/runs/43019885807)
passed. This includes typecheck, build, Runner support, Rust, native
Runner, general tests, serialized suites, all eight E2E shards, and the
required aggregate gates.
- [Greptile
review](https://github.com/paperclipai/paperclip/runs/130520170309)
passed on this head with confidence 5/5. All three review threads are
resolved. The independent Paperclip review also reports 5/5 with no
findings.
- Red at `7368a0b15c2f02107778a961144d86e2eb59a952`: `pnpm --dir server
exec vitest run
src/services/native-runtime/task-document-body.integration.test.ts`
failed because write_document removed the final newline. Cross-task and
REST cases passed.
- Green on the final source: 176 tests passed across the document body,
document key, native tool authority, task scope, document service, and
document route suites. The tests cover create, update, exact read-back,
replay, blank rejection, revision guards, and company scope.
- The ZIP shutdown regression failed before repair with “scanner did not
stop”. After repair, 54 tests passed across zip-inspection-shutdown,
private-reporter-artifacts, manual-private-cell-report-assets, and
private-evidence-budget. The regression uses a real process that ignores
SIGTERM.
- Earlier CI runs had two archive-related timeouts. The source repair
above replaces blind reruns. The Runner support suite and aggregate
verify gate now pass.
- A disposable live native document reproduced the original whitespace
loss. REST preserved the same string. The fixed handler passed local
integration tests. The running service has not been deployed.
- Local environment: Linux x64, Node 25.9.0, Vitest 5.0.3, and embedded
PostgreSQL. Local Rust preparation was unavailable because cargo is
absent. Final-head CI passed Rust verification. `pnpm verify --explain`
requested broad CI because evidence.ts is a global input. Required CI
supplied that coverage.

## Risks

Low risk. The change retains required-content validation. The product
change affects document body whitespace handling. The CI repair
forcefully stops only already-rejected archive scanners; it retains
fail-closed publication and all existing scan limits. It does not change
schema, authorization, revision guards, receipts, or persistence.

## Model Used

CI repair continuation: GPT-6.1, using repository tools and code
execution.


OpenAI Codex, GPT-6 (the exact serving model ID and context window were
not exposed in this session). Used reasoning, repository tools, and code
execution.
