DottaandPaperclip 2ec82c5774 fix(runner): preserve task context when tool connections change (#14963)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents use tools through company-scoped connections and provider
sessions.
> - Resolving a tool connection currently forces a fresh session even
when the provider can load new tools into the existing conversation.
> - A fresh provider conversation can receive too little history to
continue the task.
> - This pull request adds explicit tool-refresh capabilities and uses
them in both runner paths.
> - Fresh attempts receive bounded task history with source IDs and
retrieval instructions.
> - The benefit is that agents can continue the same task after a
connection changes.

## Linked Issues or Issue Description

**What happened?**

A resolved tool connection forced a fresh provider conversation. The new
conversation could lose the original goal and prior answers. Claude also
rejected resume when only the MCP server set changed.

**Expected behavior**

Resume the provider conversation when its harness can refresh tools.
When a fresh session is required, supply enough bounded history to
continue the task. Preserve company, agent, task, workspace, model,
instruction, and skill checks.

**Steps to reproduce**

1. Start a conversation and agree on a task and its constraints.
2. Request and connect a tool needed for the task.
3. Continue the conversation after the connection resolves.
4. Check that the agent remembers the task and can use the new tool.

**Paperclip version or commit**

The bug was reproduced on master at `c46e41e81`. This branch is rebased
on current master.

**Deployment mode**

Self-hosted server. Both legacy adapters and the native runner are
affected.

Related public work: Refs #13282 for task-backed conversations. Refs
#13057 for the broader session-compaction proposal. Refs #14659 for
another report about local CLI session continuity. This change fixes
tool-connection continuation. Provider authentication repairs keep their
existing recovery behavior.

## What Changed

- Expose tool-refresh support in native harness descriptors and legacy
adapter metadata.
- Request tool refresh after connection resolution. Keep provider
authentication repair as a fresh-session wake.
- Reload current tools and credentials while retaining supported Claude,
Codex, Grok, and other provider conversations.
- Allow MCP-only changes during qualified native recovery. Keep all
other compatibility checks.
- Refresh managed-provider and ACPX tool bindings when attaching a new
run.
- Add a fresh-session handoff for both runner paths. Bound database
reads, excerpts, and the final packet to 24,000 bytes.
- Include the original request, recent messages, decisions, plans, prior
answers, and source IDs. Mark omitted content. Apply reset boundaries,
wake cutoffs, quarantine, and secret redaction.
- Add regression tests and document the capabilities and handoff
behavior.

## Verification

- `pnpm -r typecheck` and `pnpm build` passed. Rust formatting passed.
- Final review fixes passed 314 server tests, 333 adapter utility tests,
139 native-session runtime tests, and 12 managed-provider Rust tests.
They verify historical quarantine, raised budgets across attachment, no
history reads on successful resume, and handoff delivery on fresh retry.
- Broader branch verification also passed 1,401 adapter utility tests,
1,047 runner TypeScript tests, 43 Grok adapter tests, and 311 Rust core
tests.
- Live Claude CLI and Grok ACP probes preserved the provider session ID,
recalled a prior task constraint, and called a newly added read-only MCP
tool.
- GitHub CI passed on `b21486d18084a7aa4cafbe8e012f7cad6585d9cc`: 55
successful checks and 4 skipped checks. This includes all test shards,
all eight browser shards, runner checks, and the Grok clean public npm
install canary. [CI
run](https://github.com/paperclipai/paperclip/actions/runs/37057514976).
- A full local test attempt encountered a separate Git snapshot timeout.
All affected local suites passed after the final edits, and the full CI
test gates passed.
- Review the capability matrix in `packages/paperclip-runner/README.md`.
Repeat the four reproduction steps with a supported provider and with an
unsupported harness.

## Risks

- Provider tool refresh can fail. Existing recovery falls back to a
fresh conversation where policy permits it.
- A new transport can replace an old process while preserving the
provider conversation. Tests cover current credentials and unchanged
identity.
- Long history can omit older context. Explicit markers and source IDs
let the agent retrieve needed context within task scope.
- Unknown and unqualified harnesses use the fresh-session path. No
database migration is required.

## Model Used

OpenAI Codex, GPT-6, with reasoning, tool use, code execution, and live
provider testing. The exact model ID and context-window size are not
exposed in this session. Claude and Grok also ran as test subjects.
