DottaandPaperclip 9197abf673 fix(native): preserve controller state when remote archiving fails (#19663)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native continuity replacement must preserve the state needed to
recover saved work.
> - The current replacement moves local controller files before it knows
whether the remote archive succeeded.
> - A remote failure then leaves the local controller without its
recovery files.
> - This pull request confirms the remote archive before it moves those
files.
> - A user turn that never started can use the existing bounded Retry
path after verified preservation and cleanup.
> - The task retains its saved work and can continue once under current
user authority.

## Linked Issues or Issue Description

Refs #19638, #19547, #19399 and #19659.

The prerequisite #19638 merged as
`0819f4ea78dd37fba87341b314be9dac078c1410`. This PR now targets master.
A normal dependency integration at `febed950f4` keeps only the six-file
archive repair in the PR diff. Fresh master-based CI and review are
required before merge.

**What happened?**

A native continuity replacement moved its local controller journal and
provider checkpoint. The following remote archive failed. A later
recovery attempt could no longer read the local recovery files. The
first-attempt failure also had no normal Retry receipt for the saved
user turn.

**Expected behavior**

A failed or timed-out remote archive retains the local recovery files
and starts no replacement provider. A user turn that has not started can
request one normal Retry. The existing user, provider-turn, Stop,
preservation, cleanup, budget and approval gates remain in force.

**Steps to reproduce**

1. Keep a local controller journal and provider checkpoint for a
retained remote conversation.
2. Request continuity replacement and fail or time out the remote
archive command.
3. Check the local controller files before any later recovery.
4. Settle the native failure under a current user wake and recover the
saved workspace.

## What Changed

- Confirm remote continuity archiving before moving the local controller
state.
- Add the exact remote archive failure to the shared bounded user Retry
admission from #19638.
- Verify failed, timed-out and successful archive ordering with real
local files.
- Verify ordinary failure settlement and saved-file recovery produce one
fresh successor. Keep Stop, system wake and unsettled-provider holds.
- Document the file preservation and Retry contract.

## Verification

- RED: failed and timed-out remote archives removed the local controller
files. Reading those files failed with ENOENT. The saved-user Retry
request returned false instead of true.
- Initial archive unit verification: eight cases passed, including the
three archive outcomes and five existing Cloud archive safety cases.
- Initial stacked revision: `9104ee399b`, based on #19638 at
`d22d8f9d5ee3dc36550a94d55c1d8376f3b9aab2`.
- Final master-based revision: `febed950f4`. All 13 affected cases
passed across three Vitest files after dependency integration. They
include the seven-mode real PostgreSQL completion case, saved-file
successor and negative-hold cases, and real-file archive outcomes. All
seven server typecheck layers passed again. Module boundary, whitespace
and added-code-comment checks passed. All required CI passed on this
exact head. The final snapshot has 59 successful checks, three intended
skips, one neutral result, and no pending or failed checks. Current-head
Greptile and the independent review are both 5/5, with no open findings.
- Final local revision: `9104ee399b`, macOS ARM64, Node 26.4.0, pnpm
9.15.4 and embedded PostgreSQL. The three real-file archive outcome
cases passed. The real PostgreSQL completion test passed all seven
internal scenarios, including archive failure, prior provider activity,
system wake, Stop before and after terminal settlement, and stale
runtime promotion. Own Runner/shared/SDK builds and all seven server
typecheck layers passed. Nine saved-work continuation and negative-hold
cases passed. They verify exported file contents, one user-attributed
fresh successor, idempotent hooks, no second automatic chain, and
first-use manual Retry for held cases.
- `node scripts/check-module-boundaries.mjs`, whitespace checks and the
added-code-comment audit passed.
- Focused commands from `server/`: Vitest with `-t 'retains the local
controller checkpoint until remote continuity archiving succeeds'`; `-t
'replays saved user intent through normal Retry'`; and `-t 'continues a
user turn once|does not continue automatically'`. PostgreSQL cases used
a fresh local cluster and a 120-second setup hook budget. Application
timeouts were unchanged.
- The initial stacked head passed all test, build, typecheck and E2E
jobs. Greptile and the independent review both scored it 5/5 with no
findings. These results do not replace the fresh master-based
qualification now running.

## Risks

- A remote command can fail after it changed remote state. This change
retains local evidence in that case. It does not claim a distributed
atomic transaction.
- The exact archive error can request one normal Retry only under the
existing saved-user admission. The normal path must prove stop, saved
files and cleanup before a successor starts.
- The protected launch-argument rejection remains enforced. Its exact
hosted argument difference was not available through ordinary access.
#19659 separately addresses a saved-thread feature-policy argument
difference. This PR preserves local archive evidence and does not claim
direct hosted verification of that primary cause.

## Model Used

OpenAI GPT-6 family through Codex, with reasoning, tool use and code
execution. The model is inherited; no override was used. The exact
serving model ID and context-window size are not exposed by this
runtime.
