LOC Reduction / Codebase Simplicity Review
Why this blocks
src/lib/actions/sandbox/mcp-bridge-rebuild.ts:132-135 calls assertNoAttachedProviderCredentialCollision once for every managed MCP entry. src/lib/actions/sandbox/mcp-bridge-rebuild-exec-unavailable.ts:139-168 does the same inside each read-only validation checkpoint.
The existing helper is not an entry-local check. src/lib/actions/sandbox/mcp-bridge-provider-inspection.ts:124-165 lists every provider attached to the sandbox and loads every provider record. Lines 167-181 repeat that complete inventory for one entry. An N-entry rebuild therefore repeats the same sandbox provider list and every attached-provider provider get N times at each checkpoint. The recovery path repeats the checkpoint before deletion at lines 216-236, which multiplies the duplicate work again. The exact-call test ledger already reaches eight provider commands at test/mcp-destroy-lifecycle.test.ts:1006.
Refactor direction
Make the existing collision owner plural: accept readonly McpBridgeEntry[], inspect attachments once, and compare that snapshot with every entry. Existing single-entry add and restart paths can pass [entry]; they still need their mutation-edge checks. In both rebuild paths, pass the complete entries collection once per checkpoint instead of calling the full-sandbox inspection inside the entry loop. Keep the second exec-unavailable checkpoint because it protects the deletion edge.
Expected result
Each checkpoint performs one attachment inventory instead of one inventory per managed entry. The change keeps one collision policy owner, preserves fail-before-mutation and deletion-edge revalidation, and removes repeated subprocess calls and their exact-call test bookkeeping.

Addressed the requested provider-inventory refactor at the current revision.
Validation passed: 88 affected tests, CLI type-checking, the 22-test growth guardrail, title checks, all normal commit and push hooks, and the complete npm run validate:pr workflow. All new commits are signed off and GitHub-verified. Documentation Writer Review: PASS Reviewed the complete diff against current main, including credential ownership, cleanup safety, forced-recovery checkpoints, user-visible diagnostics, tests, and documentation routing for OpenClaw, Hermes, and Deep Agents Code. The credential-storage guidance remains accurate. No documentation or writing blockers remain. |

- Line 375: Move the initial assertNoAttachedProviderCredentialCollisions check
before the prepared manifest write and any recovery detach. In the post-creation
race path around the second check, ensure provider and policy cleanup completes
successfully before restoring the prior registry record, so collision failures
do not preserve partial mutations.
In `@src/lib/actions/sandbox/mcp-bridge-provider-inspection.ts`:
- Around line 178-183: Update the collision check in the entries loop to inspect
every credential key in entry.env, not only entry.env[0]. Detect a collision
when any key belongs to an attachment, while preserving the existing exemption
for the same providerName and providerId.
In `@src/lib/actions/sandbox/mcp-bridge-restart.ts`:
- Line 128: Run assertNoAttachedProviderCredentialCollisions once on the
complete targetEntries collection before the mutation loop in the relevant
restart flow, and apply the same preflight to the complete collection in
restoreExistingMcpBridgeRuntime before its loop. Retain per-entry checks only
where needed for just-in-time revalidation, ensuring no mutations occur before
all entries pass collision validation.

LOC Reduction / Codebase Simplicity Review
Re-reviewed the exact latest PR commit c4b71b14772549a620ee4a27529eb2dfe401ab90.
The prior blocker is resolved. assertNoAttachedProviderCredentialCollisions now accepts the complete entry collection, returns before unrelated inspection for empty state, inventories attached providers once, and compares that snapshot across all entries. The ordinary rebuild passes the complete collection once, while read-only recovery performs one inventory at each of its two intentional safety checkpoints. The two-entry regression test also protects the one-inventory-per-checkpoint command shape.
I found no new blocking LOC-reduction or codebase-simplicity issue in the updated delta or complete current diff. This is a scope-limited follow-up, not an approval or a correctness, security, or CI review.

Re-reviewed the exact latest PR commit d2d2a3b1d8c37d1ed92a08541802b70c21ee0ab3.
The prior repeated-inventory blocker remains resolved. The substantive commits after the prior resolution add one plural collision preflight before the first mutation in each restart/restore flow, while retaining the singleton checks that close the per-entry race at the mutation edge. The restore regression reuses the existing restart scenario through it.each instead of adding a second end-to-end fixture.
The branch-refresh commits do not reintroduce per-entry full-sandbox inventory inside rebuild checkpoints. I found no new blocking LOC-reduction or codebase-simplicity issue in the updated complete diff. This is a scope-limited follow-up, not an approval or a correctness, security, or CI review.

Approved on head 0b26693 against base b09eece. This fixes the accepted managed MCP credential-collision defect without adding product surface. The collision paths fail closed before lifecycle mutation; 115 focused tests, CLI typecheck, strict docs validation, and repository validation pass. No actionable automated-review, security, or documentation findings remain. Required GitHub checks remain the authoritative merge gate.
Summary
Sandbox rebuild now rejects an attached provider that supplies a credential key reserved by managed MCP before changing MCP state. Forced host-side recovery repeats the collision check before sandbox deletion. The credential guide documents recovery that preserves the provider and stored credential.
