ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a cross-cutting local ACP process-launching workflow, including new settings, environment and argument handling, authentication isolation, and runtime spawning behavior. It also changes ACP defaults and contains an unresolved high-severity risk in managed-binary reference checking, so the production impact requires human review. Adjust the Minimum Blocking Severity for this repo — including turning it Off — in Settings. You can add or adjust custom eligibility rules. Learn more. |

Suggested reviewers: Merge Risk: 🔵 Low · up to The change moves the managed-binary reference check into the catalog service and wires server settings into it. Nothing in the visible evidence shows a failure. Before merging, confirm that the catalog reads the same server settings instance as the rest of the server, so uninstall reference checks see current provider configuration. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Local providers add direct command configuration and change how shared sign-in is coordinated. Commands launch without a shell, and settings remain restricted to authorized users. However, providers sharing an account store may not be stopped together when that account changes. The impact depends on the installed provider and its account-isolation behavior. Retained concerns

Note Written by the current trusted upstream contribution guide makes the triage exemption explicit: maria-rcks is listed in .github/TRIAGE_EXEMPTIONS.td. the scope objection therefore does not establish a missing-prior-approval policy violation for this author. the configured local command extends the existing ACP provider path; it preserves registry behavior and adds no credential import or login flow. independent final review found and fixed a local/registry key collision and stale managed-install references in be58ba7. both reviewers approved that head. focused blacksmith checks and fresh integrated codex/go/registry conversations passed; evidence and desktop/mobile verification limits are in the updated body. human merge approval remains with the maintainers. |

T3 Code's ACP executable override still requires an official registry entry. This adds a local-command source with a display name, executable, literal argument array, and environment overrides, while preserving the existing registry source and managed installation behavior.
DeepSeek Harness can use executable
dshand arguments["--profile","acp"]. The selected environment resolves the executable and spawns it withshell: false; the wrapper supplies existing credentials. ACP discovers models and reasoning options, preserving opaque model values such as["codex","gpt-6.1-sol"]and["opencode-go","deepseek-v4.1-flash"]exactly. Local configuration skips registry identity and sign-in, clears stale registry branding, and reports bounded readiness errors. Windows batch shims require an underlying executable.Verification on head
c3c3ea7fb5b495e52bd2f7961f790429fa2803c6:Sanitized conversation and interaction evidence.
These comparable screenshots show the existing registry mode and the new local command mode in the changed build.
Additional capability checks passed through the real client: both models used todo tools, read/edited files, called injected T3 MCP, and interpreted an uploaded image; Codex also read an uploaded text attachment. Ready checkpoints rendered the exact +1 file diff. Codex → OpenCode Go → Codex switching preserved context without rereading files, with exact model IDs verified in persisted runs. OpenCode Go recovered after a shell command exited with code 7, and native session listing returned the isolated workspace sessions.
Harness limits observed: neither selected model exposes a structured question tool. DSH advertises no audio, embedded ACP context, session/load, session/delete, or native approval modes. Its ordinary internal edit ran without requesting approval even while T3 was in Supervised mode. T3 correctly handles approval requests and guards client-mediated operations; it cannot enforce approval for a harness's own internal tools. This PR adds generic command launch and preserves existing ACP policy behavior.
current-head verification on
873258e9ca: The catalog service now owns managed-binary reference checks and the settings snapshot lock for every caller; the RPC handler only maps its typed error. Registry ids are trimmed consistently with driver decoding, legacy references remain protected, and local records do not count. Both independent reviewers approved all three exact stack heads. Blacksmith passed 51 focused catalog/adapter/websocket tests, scoped lint, and server typecheck on integrated head2d718dba8b. The real websocket uninstall preserved a referenced registry provider. Fresh dsh Codex and OpenCode Go read/edit/readback runs completed, and official OpenCode completed a file-tool conversation. Sanitized current-head runtime proof. The final one-line change makes the internally used catalog error guard private. Blacksmith passed the server export check, changed-file lint (0 warnings/errors), and 37 catalog tests on761a16874e; the preceding behavior checks above passed on2d718dba8b. Desktop shell and native mobile interaction remain unverified.gpt-6.1-sol through the codex harness.
