DottaandPaperclip c46e41e81c fix(heartbeat): validate native MCP gateway ownership (#14914)
## Thinking Path

> - Paperclip lets people manage agents and govern their tool access.
> - Native runs receive an immutable MCP tool assignment for one agent.
> - The gateway must enforce that owner when it authenticates a run
token.
> - Older gateway rows stored the owner only in metadata.
> - This change validates the gateway and profile, binds new rows, and
repairs valid older rows on reuse.
> - It also delivers each native assignment once.
> - Other agents cannot use the assignment, and explicit shared gateways
keep their configured scope.

## Linked Issues or Issue Description

Builds on #14012 by @busla (Jón Levy). That PR adds agent binding and
seven regressions. This PR carries that fix onto current master and adds
legacy authentication, profile validation, and duplicate-delivery
coverage. Related: #14864 improves discovery memory use.

**What happened?**
Native gateway creation stored an owner in metadata but left `agentId`
null. Authentication could therefore accept another agent's run token.
Managed discovery could also deliver historical native assignments
again.

**Expected behavior**
A native assignment accepts only its owner's run token. The gateway and
profile must refer to the same immutable assignment. The current
assignment enters the run configuration once.

**Steps to reproduce**
1. Run the database fixtures in `heartbeat-runtime-mcp-servers.test.ts`
on the baseline.
2. Create a native assignment and inspect its stored gateway owner.
3. Authenticate with another agent's run token, then inspect legacy
reuse and managed delivery.
4. The baseline fails six ownership and delivery cases. The fix passes
all twelve cases.

**Paperclip version or commit**
The red baseline is `f2e0f1963`. This PR is based on `cad26c6bf`, which
includes the merged discovery fix.

**Deployment mode**
Native Paperclip Runner execution and managed Codex MCP delivery.
Reproduction uses isolated database and HTTP fixtures.

## What Changed

- Store the agent owner and agent context on new native gateways.
- Validate profile and gateway assignment metadata before reuse or token
creation.
- Bind valid legacy rows with a company-scoped, null-owner update and
validate the result.
- Reject mismatched run tokens before legacy repair.
- Identify native assignments by gateway metadata, the reserved profile
key, or profile source. Reject missing or malformed provenance,
including JSON null.
- Exclude historical native assignments from managed gateway delivery.
Keep their rows for existing runs.
- Add twelve database and HTTP regressions and document the runtime
contract.

## Verification

- Red baseline: six regressions fail and four controls pass before the
initial fix. Two additional regressions reproduce metadata-loss
admission and a JSON-null TypeError before the review fix.
- All twelve ownership regressions pass on the final code, including
owner admission, cross-agent rejection, metadata loss, JSON-null HTTP
401, and explicit shared-gateway admission. Policy, listing-memory, and
discovery HTTP coverage also passes.
- Full workspace typecheck and build pass locally. Server typecheck and
compilation pass again after the review fix. The final ownership and
grant patches pass 42 combined database and HTTP regressions.
- [Full
CI](https://github.com/paperclipai/paperclip/actions/runs/37011383657)
passes for `626a08ae66361cf586105877e24d806b1a7a9c20`: all 54 checks
succeed; two optional Storybook checks skip. This includes full
typecheck, build, all test shards, all eight E2E shards, runner
verification, and the canary dry run.
- Greptile scores that exact head 5/5. No review threads remain
unresolved.

## Risks

Invalid historical native gateway or profile metadata now rejects
authentication. Valid unbound rows are repaired only when their owner
reuses the assignment. Conflicting owners are never overwritten.
Historical rows are retained for existing runs. Explicit shared gateways
use ordinary profiles and keep their configured scopes. The reserved
native profile namespace remains agent-owned even when gateway metadata
is cleared. No schema or dependency changes are included.

## Model Used

Original fix and seven regressions in #14012: Anthropic Claude Opus 5.5,
`claude-opus-5-5`, 1M context, as reported by @busla. Extensions and
verification: OpenAI Codex (GPT-6), with reasoning, repository
inspection, code execution, and tests. This session does not expose the
exact serving model identifier or context window.
