DottaandPaperclip db8a273562 fix(native): publish fresh retry sessions for later turns (#18713)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native tasks save a provider session for later comments and monitor
checks.
> - The goal projection also records the run that owns the session event
sequence.
> - A fresh retry uses a new native session, but the projection accepted
only the old session.
> - The accepted checkpoint then rejected session publication because
the goal source still named the old run.
> - This pull request lets the current task executor advance that source
after a terminal predecessor with no unfinished goal.
> - Later turns can then use the fresh retry's saved session.

## Linked Issues or Issue Description

Related: #12669, #18343. I searched open and closed PRs for source
epochs and native task-session publication. I found no duplicate repair.

**What happened?**

A successful fresh native retry could retain its predecessor's
task-session pointer. A later comment or monitor selected the old
provider session. The goal source transition required both runs to have
the same native session. The terminal checkpoint then saved a
`suppressed_newer` publication result.

**Expected behavior**

The current task executor can publish its accepted fresh session. A
later turn resumes that session. Delayed events cannot restore the old
source or revive a cleared goal.

**Steps to reproduce**

1. Complete a native turn and retain its task-session row.
2. Admit a fresh session on the same task without deleting the row.
3. Complete that turn, then send an ordinary follow-up.
4. Before this change, the saved pointer can still name the first
session.

**Paperclip version or commit**

Reproduced on source commit `36df8933f0` with a PostgreSQL regression
before the production change.

**Deployment mode**

Source checkout. The affected producer runs for local and remote native
sessions.

## What Changed

- Permit a different native session to advance the goal source only when
its run holds the task execution lock and assignee, and the task is in
progress.
- Keep the terminal predecessor, native runtime, runner identity, absent
or completed goal, source sequence, and conversation reset checks.
- Test accepted session publication, a fresh heartbeat followed by an
ordinary resumed turn, stale events, current-owner loss, and unfinished
or unreadable goals.
- Add an opt-in live Codex file-persistence check. Update execution
documentation and both recovery maps.

## Verification

- Red: the new PostgreSQL publication regression failed before the
producer change. The saved session, display ID and goal source still
named the predecessor.
- Green: 72 distinct tests passed across the final focused runs of
`runner-goals.test.ts`, `native-task-session-publication.test.ts`,
`native-session-resumption.test.ts`, and
`remote-warm-session-recovery.test.ts`.
- The assembled heartbeat test admits three turns, opens two provider
sessions, resumes the second session once, and stores three results. It
uses a deterministic provider backend.
- `node scripts/check-maps.mjs` and `git diff --check` passed.
- Real local Codex acceptance passed on macOS arm64 with `gpt-6.1-sol`
and explicit warm mode. Three heartbeat turns saved three exact file
lines. The fresh second turn published its new normalized and provider
session IDs. The ordinary third turn retained both IDs. The fixture
closed its warm owners and removed its private credential copy and
workspace. The production code was at `450e15e`; the final test-only
commit selects explicit warm mode and uses the existing owned-home
cleanup helper. The production change is identical in the final head.
- The earlier per-turn fixture preserved all three file steps and
selected the correct normalized session, but provider-thread reuse
failed. `run.attach` reported that the Codex provider had pending
events; the safe fallback used another provider thread. This remains a
separate failure. The first fixture cleanup also failed on immutable
instruction assets. The owned-home helper fixed cleanup, and the second
per-turn attempt exposed the provider identity assertion directly.
- Full current-head CI passes, including typecheck, build, general and
serialized tests, Rust/Runner checks, all eight E2E shards, and the `ci
/ e2e` and `ci / verify` aggregate gates. Greptile is 5/5 on the current
commit, with no unresolved review threads. Broad local workspace checks
were not duplicated; the focused regressions and actual provider
acceptance above were run locally. No merge, deployment, or recovery of
an original task is included.

## Risks

- Source epoch changes affect saved goal state. The fresh-session path
requires current task authority and refuses unfinished or unreadable
saved goals.
- The change starts no provider work and changes no prior-owner recovery
guard. Unknown external outcomes retain their reconciliation hold.
- A prior session remains held when it lacks the required authority or
state proof.
- Per-turn provider-thread reuse remains an open coverage gap described
above. This change does not alter that attachment guard.

## Model Used

OpenAI Codex, GPT-6 family. The exact model ID and context window are
unavailable in this session. The agent used code inspection, tools, and
executable tests.
