fix(runner): preserve durable native session authority across recovery (#13092) 

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The native runner carries tool results and task output to the
control plane.
> - A lost connection must not change which run owns a result.
> - A session must not become reusable while provider output is still
pending.
> - This pull request adds strict recovery evidence and bounded drain
barriers.
> - It preserves current PRP version negotiation and session-goal
support.
> - The benefit is safer reuse of native sessions after a transport
failure.

## Linked Issues or Issue Description

Refs #13038. This is the first of two stacked pull requests. It contains
the native runtime prerequisites. The second pull request contains the
experimental chat-channel integration. It preserves the provider
identity and typed terminal-failure contracts in #13074 and the durable
recovery work in #13075.

**What happened?**

Native session failures could leave retained provider events, incomplete
tool results, or warm handoff state that was not safe to reuse. A later
run could observe output from an earlier authority.

**Expected behavior**

Recovery must preserve exact run, tool, process, artifact, and lease
evidence. Uncertain or corrupt state must fail closed. A successful
close must prove that retained provider output is settled.

**Steps to reproduce**

Run the transport and control-plane regressions. They hold and drop
authenticated frames, fail durable writes, and restart fresh controllers
and runner processes with retained state. Provider executables are local
test fixtures.

## What Changed

- Preserve pending provider cleanup and semantic-result evidence across
session close and restart.
- Add an authenticated warm handoff with exact old and new identities,
durable receipts, and completion acknowledgement.
- Drain retained provider events under the cumulative acknowledgement
fence.
- Reject corrupt tool-result contracts without unsafe provider replay or
reusable checkpoints.
- Keep ordinary PRP v1 sessions and current session-goal behavior.
Require negotiated PRP v2 and acknowledged native session evidence
before warm authority rotation.
- Preserve late semantic inputs and exact durable result receipts until
close can prove settlement.
- Add transport, crash-window, artifact, checkpoint, and final-output
regressions.
- Deduplicate resolved execution delivery under the current issue lock.
Reuse the exact existing successor after concurrent scans or a lost
acknowledgement. Preserve newer operator evidence.
- Persist idle provider integrity/capacity failures before process
retirement, retain permanent model-rejection classification, and keep
external question identifiers out of task instructions.
- Expose only the context source on native status events. Keep thin
dispatch projections compatible without exposing the complete context.

## Verification

- Review-fix revision: 128 runtime-context/native-session tests, five
idle-failure/adjacent Rust cases, 24 warm crash-window cases, three
startup-notification/close cases, and five attach/backlog cases passed.
The security and idle-failure cases were first reproduced failing.
- Prior merged revision: runner production build, TypeScript typecheck,
complete Rust workspace tests and formatting passed; 272 focused runner
tests and two real PostgreSQL regressions passed.
- Earlier full runner runs and CI Build failed on missing
semantic-result fixture receipts, stale local provider fixture bytes,
startup-notification ordering, and a confirmation-loss fixture that
could accidentally send its final ACK. Each cause was reproduced and
corrected without relaxing production authority or close assertions.
These earlier runs are retained as failures, not represented as passing
verification.
- The first local repository-wide run failed before later phases because
the isolated install omitted PostgreSQL's native-library aliases; it
also encountered an unrelated occupied-port fixture. Those results are
retained, not represented as a passing run.
- Exact `335b2ee52709afb3885d4d6ebb2a3ece4b5864d6`: the complete runner
suite passed 1,888 tests, with 10 existing skips. The full Rust release
workspace passed with serial test scheduling. The unchanged parallel
Rust run hit the five-second 300-descendant fixture deadline; that
failure is retained. No deadline or assertion was relaxed.
- The resolved-execution regression suite passed 57 tests, including
concurrent delivery, lost acknowledgement, superseded authority, and
newer operator evidence. Plain server typecheck passed. The
duplicate-delivery cases were first reproduced failing.
- Prior exact `335b2ee52709afb3885d4d6ebb2a3ece4b5864d6` CI passed all
required jobs and Greptile reported 5/5. Its local general-server run
passed 7,208 tests but failed one responsibility fixture; later phases
did not run. The fixture started the next wake while its bounded handoff
was active. It also used nonexistent comment IDs, which hid the current
stored-message-author identity rule. The updated tests use real message
authors, preserve task ownership, and await exact automatic handoffs. No
production identity policy changed.
- Current head `aa39275a1f300f7d1a0b16cd0885eea567cff6b0` includes
current master and the native context-source projection. The focused
identity/status cohort passed 27 tests and plain server typecheck
passed. Fresh full repository tests, types, build, required CI, and
Greptile review are pending. Final results will be updated before merge.
- This is deterministic local-provider evidence. It is not a claim of
complete live-provider qualification.

## Risks

- This changes authenticated recovery and close ordering. The TypeScript
transport and runner binary must be built from the same revision.
- Failed or incomplete evidence intentionally prevents reuse and can
require a fresh run.
- PRP v1 ordinary/cold sessions remain supported. A v1 connection lease
cannot upgrade in place. A current v2-capable runner held on a v1 lease
was qualified through owned-process retirement/join, fresh bootstrap on
the same old authority, v2 observation/ACK, then warm rotation. Legacy
binary replacement and adopted-owner migration are not qualified by that
test; rollout must not present them as automatic same-lease upgrades.
- This pull request has no database migration or chat-channel
activation. The second pull request keeps the channel feature
experimental.

## Model Used

OpenAI Codex assisted with implementation, tool execution, tests, and
reconciliation. The existing implementation records OpenAI `gpt-6-astra`
assistance. The current environment does not report a context-window
size. No private reasoning traces are included.

@ -184,6 +184,33 @@ If recovery cannot be truthful, state names the outcome. For example, failure
to reserve storage for a P0 event records `p0_storage_exhausted` and the
`unrecoverable` lifecycle. It never reports a fresh session as resumed.
## Protocol versions and warm handoff
Ordinary PRP v1 connections remain supported. A warm `run.attach` that changes
run authority requires negotiated PRP v2, as well as the warm-transition
capability. The runner refuses a v1 warm attachment before provider work. A v1
peer acknowledges placeholders for native session-goal and capability events;
those acknowledgements do not prove that the peer observed the native state.
Rotation must not discard that retained evidence or relabel it as a new run.
A connection lease fixes its protocol version. Advertising v2 on reconnect
does not upgrade an existing v1 lease. For a v2-capable runner holding a v1
lease, the owned transport's process-recovery path can replace the process
with fresh authorization when configured with a reconnect grace. It preserves
validated state and original authority and issues a new one-use bootstrap.
The old process must exit first; any old provider owner must also be retired.
The connection lease exists only in process
memory; no credential or journal file needs to be edited. The replacement
negotiates v2 and replays retained native session state on the original
authority. Its native event acknowledgements must settle before warm handoff.
The controller must still authorize replacement and verify current process,
artifact, and run ownership. This is not an automatic in-place lease upgrade
or a general operator UI migration flow. An old binary stays old when its
immutable launcher restarts it. Replacing a legacy binary or an adopted owner
requires separate artifact and ownership admission; this path does not qualify
that migration. Pending warm-transition receipts
require their separate exact recovery admission, not an ordinary bootstrap.
## Backpressure and bounded storage
The runner has a byte limit and a reserved P0 region.
