Nicky LeachandPaperclip 8b4ab65b1c Add plugin-owned project storage and task workspaces (#17001)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Tasks can use isolated repository workspaces.
> - Core currently prepares those repositories on its own filesystem.
> - A storage provider may only expose repositories inside remote agent
computers.
> - Project storage and task workspace preparation must have one
provider owner.
> - This pull request adds that contract and keeps execution as a
separate plugin interface.
> - Core keeps authorization, durable task bindings, and lifecycle
fences.

## Linked Issues or Issue Description

**Subsystem affected**

Plugin SDK, project workspace policy, heartbeat preparation, execution
leases, and workspace lifecycle.

**Problem or motivation**

Core cannot prepare a task workspace when its repository storage is
unavailable on the Core host. An execution lease must not be required
just to prepare persistent storage.

**Proposed solution**

Let one plugin provide project resource lifecycle and workspace prepare,
inspect, restore, and remove behavior. Core reserves a task workspace
before it calls the plugin. The plugin returns an opaque durable
reference. The matching execution plugin receives that reference on its
task RPC.

**Alternatives considered**

Preparing repositories on Core would require a provider mount on Core.
Preparing them only during task launch would tie persistent workspace
lifecycle to execution leases and agent availability.

**Roadmap alignment**

This extends the remote provider model in ROADMAP.md. Related execution
work is in #16978. This PR does not replace that task bridge. Native
execution of managed storage requires the bridge; this change fails
closed when it is absent.

## What Changed

- Add one storage provider declaration with supported modes/strategies,
a capability, a validated RPC contract, and a test harness.
- Persist provider ownership, repository revision, and
execution-workspace identity before external effects. Reconcile retries
with a stable operation ID.
- Prepare provider storage before environment acquisition. Keep Core
filesystem preparation out of this path.
- Pin the durable reference to the matching execution plugin and
validate the lease binding before task dispatch.
- Route inspection, reopen, and removal through the existing lifecycle
process. Keep local data when remote recovery is uncertain.
- Keep the application database pool free during lifecycle locks.
Preserve pending workspace selections, validate source edits before
retirement, and retry unfinished closed storage cleanup.
- Protect provider metadata and live repository sources from caller
edits. Storage edits retire only closed records with confirmed removal;
retired records cannot reopen.

## Verification

- Current head `8214b3ca5`: all 25 provider lifecycle tests pass with
`maxConnections=1`. They cover preparation, inspection, reopening,
removal, a paused provider with responsive ordinary SQL and a competing
source edit, pending selection preservation, rejected source edits,
cleanup retry scheduling, and providers that cache operation results,
and committed cleanup notifications for storage intent and recovered
state.
- Final frozen-tree lifecycle run on `8214b3ca5`: all 318 tests passed
in 10 files, covering workspace services, reopen, compaction, task
binding, project sources, heartbeat preparation, display caching, and
source locks.
- Direct server `tsc --noEmit` passes. The SDK build and all 128 SDK
tests passed during initial verification; later SDK changes are
documentation only.
- Full CI on the previous head `ec5c7209a` passed all 55 applicable
checks; 2 conditional checks skipped. Standard Greptile reviewed current
head `342e6d9c3` at 5/5 with no unresolved threads. All 55 applicable CI
checks passed on `342e6d9c3`; 2 conditional checks skipped. The Slack
browser and CLI startup jobs passed on their single unchanged-head
rerun. Its Apex review returned 4/5 with one pending-restoration issue.
Commit `1b58943b1` reconciles that durable intent before cleanup,
advances the generation without reopening the Core row, and blocks
direct removal or retirement while intent remains unresolved. Standard
Greptile reviewed `1b58943b1` at 5/5 with no new findings. All 54
applicable CI checks passed on `1b58943b1`; 3 conditional checks
skipped. The chat job passed on its single unchanged-head rerun. Apex
then returned 4/5 for a missing cleanup wake after recovery. Commit
`8214b3ca5` atomically registers cleanup intent before storage intent
and recovery-result writes. Its provider test observes real committed
notification hints and the visible advanced generation. Standard
Greptile reviewed `8214b3ca5` at 5/5 with no new findings. All 55
applicable current-head CI checks passed on the first run; 2 conditional
checks skipped. Final Apex verification completed at 5/5 on this exact
head: 38 files reviewed, no new comments, and no unresolved threads. The
PR is ready for review and mergeable.
- The first Apex review found five issues after a standard 5/5:
application-pool starvation, stale pending selections, retirement during
rejected source edits, lost cleanup retries, and reused inspection
identities. Commits `6d72e7fd4` and `342e6d9c3` fix each with regression
coverage. Archive lock waits use dedicated connections, and source edits
fail promptly if the lifecycle is busy. Retirement compares normalized
values. The normalized-source regression initially failed with the
raw-value comparison; after moving the check after normalization, a
clean provider-suite rerun passed all 24 tests at that stage. Those
threads are resolved; the earlier Apex 0/5 is not a passing acceptance
result.
- Earlier local integration attempts could not bind localhost inside the
sandbox. The same suites passed with permission to start local
PostgreSQL.
- The earlier broad local `pnpm test:run` overlapped edits and reported
stale-revision and checkout-path/Git-fixture failures. It was not a
final-tree result. Full CI subsequently passed; the original local
failure remains part of verification history.
- Local repository-wide typecheck/build cannot complete because `cargo`
is unavailable. Direct server TypeScript checks and affected tests pass;
full Rust and build validation comes from CI.
- An earlier browser run on `ff918c5a8` failed in the unchanged
case-filter journey: expected “Done,” received “All statuses,” with an
announcement handler recorded during the assertion. The cause is not
confirmed. [The failed
job](https://github.com/paperclipai/paperclip/actions/runs/39500611857/job/118896954508)
remains verification history. The unchanged shard passed in the next
full CI run on `ec5c7209a`; no UI or fixture change was made.
- Current-head browser shard 2 failed waiting five seconds for the
mocked Slack setup Success heading. This PR changes neither that UI nor
its fixture. [The failed
job](https://github.com/paperclipai/paperclip/actions/runs/39506070513/job/118916021232)
remains verification evidence. The cause is not confirmed; the single
unchanged-shard rerun passed; no UI or fixture change was made, and the
original cause remains unconfirmed.
- The workspace test shard passed its 3,978 general tests, then its CLI
company-import/export fixture timed out after 30 seconds waiting for
startup health before creating any company or workspace. [The failed
job](https://github.com/paperclipai/paperclip/actions/runs/39506070513/job/118916021855)
remains verification history. The child reached external-PostgreSQL
startup without exiting or reporting an exception. Its cause is not
confirmed; the single unchanged-job rerun passed, including the CLI
fixture. No startup or fixture change was made, and the original cause
remains unconfirmed.
- The new cached-removal regression initially failed because its fake
worker advertised availability for unrelated fixture plugins, so another
workspace changed its fake checkout state. Worker availability now
matches the fixture plugin; the complete 25-test provider suite passes.
- On `1b58943b1`, the chat shard timed out polling for one conversation
after an authorized GitHub description edit. [The failed
job](https://github.com/paperclipai/paperclip/actions/runs/39510521657/job/118930193418)
remains evidence. The exact case passes locally against PostgreSQL (1
passed, 1,380 unrelated cases skipped), and this PR changes neither that
test nor its handler. The original cause is unconfirmed; the single
unchanged-job CI rerun passed without a code or fixture change. The
original cause remains unconfirmed.
- The diff was checked for credentials, private references, and
generated artifacts.

## Risks

This is an additive provider contract with no database migration.
Existing projects keep their local behavior unless their policy selects
a storage plugin. A selected provider must be ready and enabled. Unknown
or unsafe cleanup fails closed.

Managed native execution depends on #16978. Core refuses a host Runner
fallback. Providers must fence lifecycle generations, preserve ambiguous
retries, and report remote recovery honestly. Provider-specific live
storage and guest mount qualification remain separate from these Core
contract tests.

## Model Used

OpenAI Codex (GPT-6), with repository inspection, code execution, and
tests. The exact model variant was not exposed.
