DottaandPaperclip 919ddbf46d fix(workspaces): read committed files before live allocations (#18677)
## Thinking Path

> - Paperclip keeps task files in managed workspaces.
> - A final remote save commits a durable snapshot and clears writer
authority.
> - The old allocation can remain recorded while its transport becomes
unavailable.
> - Files still tried that live allocation before the accepted saved
version.
> - This PR reads the validated save when authority is clean and no
writer owns it.
> - Dirty work and active writers still require the live allocation.

## Linked Issues or Issue Description

Related: #18403 introduced remote Files access. #18665 fixes a separate
completion-settlement issue and is included in the base.

**What happened?**

A file preview returned `422 workspace_unavailable` after a remote task
had saved its files. Its clean authority still had a live location. The
same original bytes were readable from the committed save after that
location cleared. The exact original live transport failure is unknown.

**Expected behavior**

Once the workspace is clean and has no writer, Files reads its exact
current committed save. A retained location must not make accepted files
depend on remote command execution.

**Steps to reproduce**

Create a real committed workspace archive. Keep its allocation active in
the recorded authority. Clear dirty state and writer authority. Make
live execution unavailable, then request the ordinary file preview
route. Before this fix it returns 422. After this fix it returns the
saved bytes without a provider command.

## What Changed

- Select the saved-file loader before consulting a live location when
authority is clean and has no writer.
- Keep exact company, workspace, snapshot, archive, and authority-change
checks.
- Keep the live path for dirty work and active writers. Never substitute
their older saved bytes.
- Cover browse, resolve, preview, download, rejection controls, and
saved-copy cleanup through real routes and storage.
- Document the selection rule and update its feature and access-map
recipes.

## Verification

- Red: the new ordinary-route regression expected HTTP 200 but received
422 against the old service.
- A separate compatibility control reproduced the optional-loader
regression. Valid live reads still work when the loader is absent;
no-location reads still fail, and a configured invalid save never falls
back to live bytes.
- Green: 98 ordinary file-route and authorization tests passed with real
PostgreSQL and archive storage.
- All 46 opt-in remote workspace lifecycle tests passed against one
owned local disposable PostgreSQL database. Its database, server, and
files were cleaned after the run. No live S3 or provider flags were
enabled.
- Full workspace typecheck passed after the optional-loader
compatibility repair. Full build passed locally before that narrow
repair. All normal CI checks pass on the current head, including build
and server suites. The separate Paperclip Review job and the full local
test suite remain in progress.
- Feature/access-map validation and `git diff --check` passed.
- A read-only staging check preserved and verified the original saved
bytes. It did not rerun the agent or qualify the failed journey. The
fixed active-location path has local regression evidence; deployed
acceptance is pending.

## Risks

A clean workspace now uses the existing bounded saved-archive loader
while a location remains recorded. Each Files request can retrieve and
extract that archive. Existing disk, size, concurrency, cancellation,
and cleanup bounds remain. A dirty workspace or current writer still
uses live files and fails closed when they are unavailable. This change
neither releases compute nor changes access permissions. It does not
identify the original provider RPC subreason.

## Model Used

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