DottaandPaperclip 0934b834c4 perf(workspaces): release retained cohort parent scratch early (#20447)
## Thinking Path

> - Paperclip manages agent work and preserves its workspace files.
> - Online migration captures local files and publishes remote workspace
authority.
> - Each capture verifies encrypted readback, restores the archive and
compares the current source.
> - A cohort kept every completed parent payload until the whole cohort
published.
> - A larger cohort could retain many complete copies while later
members still worked.
> - This pull request releases only finished parent payloads before a
capture worker starts another member.
> - Nested-child proof, final fresh checks and atomic publication keep
their existing owners.

## Linked Issues or Issue Description

Refs: #20418, #20437, #20441.

**What happened?**

A cohort retained each member's capture archive, verified archive,
comparison archive and restored tree until atomic publication. The
capture worker limit did not limit that retained parent data.

**Expected behavior**

Release completed parent payloads once their consumers finish. Keep
files that a later publication check still needs.

**Steps to reproduce**

Run the added held-peer regression against the previous owner. It
completes one parent, holds a later member and finds all four completed
parent paths still present.

## What Changed

- Release three named parent archives and the restored tree after a
successful online cohort capture, before that worker takes another
member.
- Keep parent scratch roots and all nested-child verification areas.
Keep every final fresh child and publication check.
- Retain payloads for archived repository intents. Use the existing
writable-tree cleanup for read-only restored directories.
- Add real filesystem regressions for early release, retained child
proof, late child mutation and the final archived-intent path check.
Update the source-fence guide.

This branch incorporates the final #20441 owner and both distinct
saved-relative-path regressions. Its scratch-specific production change
is nine added lines and one removed line. Single imports and saved
journal/archive formats stay unchanged.

## Verification

- Canonical Node24 preflight passed. The Runner build came from the
content cache. After the current-master merge, the preflight checked
1,674 inputs and 1,817 outputs and found unchanged build inputs. Plugin
SDK prerequisites passed.
- Genuine RED on the unchanged #20441 owner: one held-peer case failed
at four retained payload paths; the archived-intent control passed. The
run took21.14s, with221 unrelated cases intentionally unselected. The
first sandbox-restricted setup attempt hit DNS errors and was stopped;
the normal network-qualified preflight then passed.
- Initial treatment: four selected PostgreSQL/filesystem cases passed
in38.61s, with219 intentionally unselected. The held peer observes
released parent payloads and retained child areas. A later child
mutation still refuses the whole cohort and publishes no authority or
activity.
- The archived-intent control observes all parent payloads at the actual
final saved-relative-path check. The changed path refuses publication
and keeps task/repository state intact. This exercises its actual
singleton owner; archived-only sources do not enter the online cohort
API.
- After a normal merge of current master and the final #20441 test, the
five affected cases and server TypeScript passed. No full local matrix
was repeated. Initial CI failed the inherited recovered-upload assertion
because the new retention test leaked its archive and filesystem spies.
That case passed alone but failed in the adjacent three-case sequence
(two pass, one fail); scoped `finally` cleanup made the same sequence
pass three of three in17.15s, with191 unrelated cases intentionally
unselected. No upstream assertion or production code changed. Server
TypeScript passed again. All required
[CI](https://github.com/paperclipai/paperclip/actions/runs/42746586511)
passed on final normal-merge head
`604c0f67bf7282ecd3f6e5e5da1c9d8637ef70cc` (56 success, four skipped and
one neutral; no pending or failing checks). The previously failing
server4/12 passed in10m23s. Fresh Greptile is5/5 on that exact head with
no open threads. The merge resolves the duplicate #20441 squash
insertion; both tested owner and test files are byte-for-byte identical
to repair head `b5c8eed82b6a676985e1a8af785e5df2ae3be2ce`. The prior
head received
[Greptile5/5](https://github.com/paperclipai/paperclip/pull/20447#issuecomment-6757435885);
its archived-cohort coverage warning was [answered using the actual
public admission
boundary](https://github.com/paperclipai/paperclip/pull/20447#discussion_r4520641017).
- `git diff --check` passed. No hosted cleanup, migration, provider
action or deployment was performed.

```sh
node scripts/agent-preflight.mjs --skip-rust-debug
pnpm --filter @paperclipai/plugin-sdk ensure-build-deps
node --import ./cli/node_modules/tsx/dist/loader.mjs packages/db/src/test-postgres-command.ts pnpm exec vitest run server/src/services/remote-workspace-cohort-migration.test.ts server/src/services/remote-workspace-migration.test.ts -t 'releases completed parent payload|retains archived intent payload|shares the merged child verifier|rechecks the current archived repository intent path at publication'
pnpm --filter @paperclipai/server exec tsc --noEmit
```

## Risks

- This reduces retained parent data. It does not establish a total disk
bound. Active capture/encryption/readback files and retained child areas
still need measured capacity.
- Cleanup failure uses the existing worker abort and peer-join path
before publication. Original source files, uploaded objects and journals
remain intact.
- Archived repository intents still need their restored payload at
publication. Those payloads stay retained. No capture limit, budget or
integrity guard changes.
- Saved operations and archive identities carry forward unchanged.
Resume still uses the existing full source and authenticated object
checks.

## Model Used

OpenAI GPT-6 (Codex), with tool use and code execution. The runtime does
not expose a more specific model ID or context-window size.
