DottaandPaperclip 71a20453e1 fix(workspaces): honor inherited remote workspace bindings (#18611)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Task creation can bind a child to its parent's execution workspace.
> - Native sandbox runs reserve that workspace before the provider
starts.
> - Remote reservation rejected inherited isolated workspaces and
operator branches because the original source task differed.
> - This check stopped valid child tasks before their existing access
and writer checks could run.
> - This pull request uses the persisted binding and existing
source-access checks to admit that continuation.
> - The benefit is that authorized child tasks can continue saved work
while the single-writer lock stays effective.

## Linked Issues or Issue Description

**What happened?**

A child inherited an active isolated remote workspace through normal
task creation. Its next run failed during setup with `Workspace
ownership changed.` No provider work started. The reservation guard
treated the original `sourceIssueId` as exclusive ownership, although
task creation had persisted a valid child binding.

**Expected behavior**

A bound child or follow-up can reserve the workspace after the prior
writer saves. Current task/run access, source visibility, trust, company
scope, closed-workspace state, and writer checks must still apply. The
original source task remains provenance.

**Steps to reproduce**

1. Create a task with an active saved remote isolated workspace or
operator branch.
2. Create a child without an explicit workspace override.
3. Confirm that the child inherited the execution workspace ID.
4. Start its native sandbox run. The old reservation guard rejects it
before provider execution.

**Paperclip version or commit**

Reproduced on source based on
`06bc8db75c71142ed108e0f331394c5187015d6a`. The same guard is present at
`1a6017d6460267ad89d7e1784e2b521c28d8e9ac`.

Related: #17156 proposes separate workspaces for child tasks. This
repair preserves the current inheritance contract and enforces the
remote writer lock. #16911 addresses child bindings across repositories.

## What Changed

- Remove the original-task equality restriction for active remote
workspaces. Keep the existing persisted-binding and retained-source
authorization path. Explicit task-root selection follows the existing V1
filesystem contract; task-assignment grants do not define filesystem
permissions.
- Keep closed workspace rejection and unfinished-writer checks.
- Add database-backed regressions for inheritance, replay, competing
children, an unbound task, private source data, company isolation, and
closed records.
- Extend real save/restore tests for inherited isolated workspaces and
operator branches. Keep shared-workspace discovery coverage.
- Update the development guide and workspace maps.

## Verification

- Red: before the repair, the inherited isolated/operator cases fail
with `Workspace ownership changed.` The shared case passes. The unfixed
suite has five failures and four passes.
- Green: 11 reservation cases pass with real PostgreSQL 18 in an
isolated Docker container.
- An earlier run of the four affected workspace/preparation/trust suites
passed 191 tests. The review follow-up passes all 15 selected
reservation/save/restore cases. Inherited cases remove the original
files, use a distinct allocation and target, restore the saved file,
append child work, and independently read that work from the child's new
snapshot. Shared-source discovery stays covered. The filter excludes 42
other integration cases.
- `pnpm -r typecheck`, `pnpm build`, `node scripts/check-maps.mjs`, and
`git diff --check` pass. A direct server typecheck also passes after the
final test edit.
- `pnpm test:run` stopped in its first chat shard: 338 passed, one
Discord receiver-lease setup failure, 1,478 outside the shard. The
failing test passes in isolation on both the unchanged baseline and the
fix. Its suite-order failure is not explained by that retry and remains
recorded. The unchanged baseline also fails three other Discord
publication cases in that chat shard, while its next chat shard passes.
This does not reproduce or explain the original lease failure; both
results remain recorded. CI is complete on `e697f6e1b8`: 54 successful
check runs, one successful legacy status, three skipped checks, and one
neutral check. No check is pending or failed. Greptile gives this commit
5/5 with no remaining findings. The security reviewer accepted the
V1-contract explanation; both review threads are resolved.
- Live sandbox acceptance remains unverified. The available test
credentials could not resolve the required sandbox snapshot. The
provider rejected creation before workspace execution, and a scoped
follow-up found no allocation. No live model turn, deployment, or
original-task recovery is claimed.
- Local environment: macOS arm64, Node 26.4.0, pnpm 9.15.4. Native
PostgreSQL startup hit the host semaphore limit; tests use disposable
Docker databases. No shared database was reset.

## Risks

- A bound child can now write after the prior writer releases the
workspace. Incorrect binding or access checks could expose source data.
Regressions cover unbound, private-source, and foreign-company
rejection.
- Concurrent children must not become two writers. A real transaction
race grants exactly one reservation; saved-file tests keep the second
writer blocked until save completes.
- No schema or migration changes. This PR does not change task-creation
inheritance, requested models, credentials, trust, approval gates, or
recovery budgets.

## Model Used

- OpenAI Codex, based on GPT-6. The exact serving model ID and context
window are not exposed in this session. Used reasoning, tool use, code
execution, and browser diagnostics. No sub-agents were used.
