DottaandPaperclip 7c7d2d8d2c fix(runtime): continue from saved sources after workspace loss (#16690)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The runtime must preserve saved work and prevent duplicate
execution.
> - Older cleanup could destroy a sandbox before its workspace export
finished.
> - The existing recovery controls require either the original sandbox
or recovered original files.
> - Surviving attachments can support a rebuild, but they do not prove
that missing edits were recovered.
> - This pull request adds an explicit reconstruction decision and one
fresh continuation through the normal execution gates.
> - Operators can continue useful work while the original failed run
remains truthful.

## Linked Issues or Issue Description

**What happened?**

A historical failed export can have an accepted result, a prepared
workspace descriptor, and a confirmed destroyed sandbox. Its notice can
also say `new_source_execution_path` and disappear. The task then has
neither a truthful original-file repair path nor a supported
reconstruction path.

**Expected behavior**

Keep the missing-file obligation visible. Let an authorized operator
choose surviving task attachments and record lost work and external
action outcomes. Start one fresh continuation after current execution
checks. Keep the old result and failed export intact.

**Steps to reproduce**

1. Seed a failed native export with a prepared descriptor and an exact
destroyed-lease receipt.
2. Resolve its notice with the historical `new_source_execution_path`
bookkeeping value.
3. Read the task. The baseline hides the hold even though no source
reconciliation exists.
4. With this change, choose **Continue from saved sources** and submit a
reconstruction decision.

Related public work: #16451 preserves healthy warm sessions. #16583
prevents destructive cleanup of unexported work. This change handles
historical source loss that those fixes cannot undo. Searches of open
and closed work found no equivalent reconstruction endpoint.

## What Changed

- Add a board-only reconstruction endpoint with `runtime:manage` and
task visibility checks.
- Validate the exact run, result, descriptor and destroyed lease. Reject
active copyback, competing owners, newer work, stale task status, and
foreign attachments.
- Record attachment hashes, missing work, and external action outcomes.
Preserve the original failed run, accepted result, prepared descriptor
and terminal failure.
- Hold other continuation paths until the durable reconstruction intent
admits its successor. Record that successor in the same transaction and
preserve the retry count.
- Add an operator control that distinguishes reconstruction from
original-file recovery. Update the recovery runbook and capability maps.

## Verification

- Exact baseline source returns no blocker for the destroyed-source
fixture. The same fixture returns a required recovery hold with this
change.
- New real PostgreSQL and assembled API/heartbeat suite: 25/25 pass. It
covers duplicate submissions, lost acknowledgement, context reset,
source identity, task ownership, concurrent execution attachment scope,
later human blocks, deleted sources and agent pause.
- Existing export retry, explicit continuation and recovery-action
suites: 386 cases pass. One new-fixture constraint error in the combined
run was corrected; the full new suite then passed.
- UI recovery suites: 46/46 pass across three files. They cover disabled
actions, loss acknowledgement, failure retention and runtime authority.
- `pnpm -r typecheck` and `pnpm build` pass. The first sandboxed
typecheck attempt could not open the TypeScript IPC socket; the
authorized rerun passed.
- Module boundaries, map checks, token gates and diff whitespace checks
pass.
- OpenAPI route coverage: 21/21 pass. The first CI head exposed a
missing endpoint registration; this head adds the registration and the
focused suite passes.
- Review identified a missing dispatch-time check and an isolated
attachment cache. Both are fixed. Claim and final handoff recheck the
exact successor, sources and current execution gates. A controlled
post-claim operator block prevents the assembled heartbeat from entering
the provider. The shared attachment cache refreshes uploads and removes
deleted selections.
- Final focused run: 180/180 pass across six suites, including
reconstruction, existing dispatch/stale-queue contracts and UI recovery.
- A second review reproduced cancellation by an already satisfied
historical connection card while the task was `todo`. Read-only
connection availability now works before checkout; active-task mutation
checks remain strict. The baseline failed two cases; after the fix all
74 connection and reconstruction tests pass, including revoked access,
pending questions and pending approvals.
- All current-head CI gates pass on
`9d197236da11fa24f1ceadf5589cb2b81179d824`, including general/serialized
tests, Runner, build and browser gates. Greptile is 5/5 for that exact
head with no unresolved threads. The full local `pnpm test:run` is still
running its serial server group; no full local pass is claimed. Live
staging recovery is pending deployment.

## Risks

- Reconstruction cannot restore missing bytes. The operator must
identify surviving sources and actions that must not be repeated. The
agent must verify those attachments before rebuilding.
- This path is limited to exact, confirmed destroyed remote sources with
an accepted result. Retained or uncertain sources keep their existing
repair path.
- No schema migration, credential change, budget increase or
warm-session policy change is included. Normal pause, ownership, budget,
approval and dispatch gates still apply.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, tool use and code execution.
The session does not expose an exact backend model ID or context-window
size.
