DottaandPaperclip e54354d9d3 fix(ai-connections): save quota credentials without recovery files (#18352)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Managed AI connections keep the selected account in the secret
store.
> - Server quota refresh can receive a replacement token before its
database save commits.
> - That path currently writes an encrypted recovery file on the web
server.
> - Cloud web replacement should not need that file to use a saved
account.
> - This pull request saves the replacement directly and retries the
same value in memory.
> - The benefit is a smaller cloud storage contract with an explicit
sign-in recovery limit.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Server-owned OpenAI quota refresh and credential persistence during web
replacement.

**Current behavior**

Quota refresh checks local encrypted recovery storage before token
exchange. It writes the replacement to that storage before the secret
transaction commits. A replacement web receiver can therefore need the
old web volume.

**Proposed behavior**

Required database reads and locks must succeed before exchange. The same
logical refresh saves its returned replacement directly, with at most
three save attempts. It checks the current secret after an uncertain
commit response. A process that loses the unsaved replacement can
require sign-in again.

**Reason and benefit**

Postgres remains authoritative. This removes new quota recovery files
without adding another credential vault. Existing files remain readable
for cutover. Local-only Google retirement keeps its existing behavior.
Remote Google subscription sessions remain unsupported.

Related public work: Refs #14056 for managed Codex credential handover.
Searched open and closed credential-refresh pull requests; this change
does not duplicate their provider login work.

## What Changed

- Keep the exchanged replacement and its source generation in the
current refresh operation. Save retries do not repeat OAuth exchange.
- Reconcile a lost commit response from the saved credential. Grant
changes, secret versions, session epochs, selectors, and revocation
prevent a stale save.
- Stop creating or preparing quota recovery files. Preserve existing
record settlement and local Google compatibility.
- Document the v1 sign-in limit and existing Runner
persistence-before-completion contract.
- Add PostgreSQL and controlled-provider regressions for save rollback,
lost replies, revoked or changed authority, receiver process loss, and
pending Runner credential handover.

## Verification

- [Complete current-head
CI](https://github.com/paperclipai/paperclip/actions/runs/41099132607)
passed at `e4ed6551a707c814ddb2395a7358106b1e04857a`: 53 successful
checks and two intended skips. This includes full typecheck, tests,
build, and E2E gates.

- `pnpm -r typecheck` and `pnpm build` passed at
`1ebe75984be9bf19d518728d4ff440a2d7f3dbce`. Later branch changes only
repair tests. Rebase adds an unrelated master UI performance fix; the
credential and Runner handover source did not change.
- Focused credential tests passed: 2 files, 160 tests (145.62s).
Command: `pnpm exec vitest run
server/src/__tests__/ai-connections.test.ts
server/src/__tests__/plugin-task-credential-writeback.test.ts
--maxWorkers=1 --no-file-parallelism`.
- `pnpm test:run` was deliberately interrupted after 17m41s in its first
general-server chat integration phase, before any suite result. The
controller exited 130 and its wrapper exited 1. This is an incomplete
local run, not a full local pass or an observed test failure. The
coordinator stopped duplicate long local work; the complete current-head
CI suite subsequently passed. All owned test and PostgreSQL processes
were confirmed stopped.
- Database tests use real PostgreSQL 18.6 with POSIX semaphores through
a test-only loader. Provider requests use controlled fixtures; no
production OAuth mutation was made.
- Greptile reviewed current head
`e4ed6551a707c814ddb2395a7358106b1e04857a` at 5/5 with zero comments.
- The captured focused-test logs contain none of the replacement-token
fixture values.
- The receiver-loss test kills a separate Node process after one HTTP
token exchange while PostgreSQL blocks its secret insert. A new receiver
then uses the existing sign-in flow.
- The Runner case rejects a real deferred secret commit. Provider
completion remains uncalled until a new receiver commits the retained
credential.
- Initial setup failed because this host exhausted System V semaphore
resources. Another setup attempt lacked built SDK entries. Both were
setup failures, not passes. After setup repair, the first real run
passed 159/160 tests; the remaining test asserted the retired
directory-fsync contract. The replacement test forbids recovery writes
and requires one committed exchange without a file.

## Risks

- If all three saves fail and the producing server process exits, the
unsaved replacement is lost. The next failed use can require sign-in
again. This is the accepted v1 limit.
- Existing unresolved recovery files still require inventory and
settlement before their old volume is removed. This PR does not perform
deployment or delete those records.
- Local Google subscription retirement still needs its existing local
recovery ownership. It is outside the supported remote cloud scope.

## Model Used

OpenAI `gpt-6.1-sol`, with reasoning, repository tools, code execution,
and controlled integration tests. The context window size was not
supplied.
