From 21825c7d78c73f4b5dbf2cbe82e95723d707c10e Mon Sep 17 00:00:00 2001 From: Pengfei Hu Date: Fri, 2 Oct 2026 10:27:14 -0700 Subject: [PATCH 1/2] Stop an empty preflight plan from granting merge and completion (#610) A preflight plan that named nothing to route returned the shared `complete` state, whose permission vector grants `merge` and `report_complete`, with no verifier run or current-control identity behind it. The published 0.5 schema also refused that payload, because it pinned `update_pr` to false. Preflight 0.6 gives `control` its own union: the new `planning_complete`, `agent_action_required` and `human_review_required`. `planning_complete` owes no action and authorizes nothing. `complete` and `review_publishable` cannot appear, and every permission is false on every route, in the model and the generated schema alike. The shared AgentControl union is unchanged, so minimum_control_contract_version stays 21. - Both base-preflight readers now parse through one version ladder (`parse_preflight_result`). A stored 0.5 answer still reads as 0.5. - The hook script accepts preflight 0.5 and 0.6. - The adoption scorer reads `planning_complete` as itself. - The CLI text says the result authorizes nothing. - Contract 41 -> 42. Preflight 0.5 is frozen and pinned by digest. Docs, STABILITY migration note and CHANGELOG are updated. The Route H dry run was re-run on contract 42. - AGENTS.md edits were approved by the owner in conversation on 2026-10-01.

1ea9c02312d1e9dc76ec11e86d28a3a30c226256 Mon Sep 17 00:00:00 2001 From: Pengfei Hu Date: Fri, 2 Oct 2026 12:19:53 -0700 Subject: [PATCH 2/2] Address #925 review: planning_only, stated vectors, fail-closed readers Review of the first commit (10 finder angles, verification and a gap sweep) confirmed the following. Each fix has a test that fails without it. - Rename the new state `planning_complete` -> `planning_only` (owner- approved). A state named "...complete" invites the misreading #610 is about, and the adoption scorer's completion matcher fired on the CLI's own "planning complete" line. - `parse_preflight_result` used the payload's version as a dict key, so a list or object version raised TypeError: CLI exit 4 internal_error instead of exit 2 config_error, and a bare TypeError on the MCP path. Non-string versions are now read as unrecognised. - The generated hook's version and touch-kind checks used set membership, which hashes. A malformed answer crashed the hook, and Claude Code then let the edit through unprompted. Tuples compare instead, so the prompt stays. - A stored 0.6 control must state all six permissions, in the model as in the schema. Shared variants rebuilt an absent or partial vector. A `planning_only` answer must also carry no changed file, touch, signal, evidence or command, in both the model and the schema. - `_plans_authorize_nothing` could never fire, so it is removed. The all-denied schema fragment is shared with the control envelope, whose frozen schema is byte-identical. The planning rule reuses v0.3's and the required list is borrowed. - Adoption scorer: a preflight answer that is not a human stop no longer sets the live permission vector. It was failing every edit after a planless preflight, which the 10-agents-md template prescribes. It also no longer revokes an earlier verifier `complete`. A parity test now pins the scorer's state vocabulary to the shared union plus preflight's. - A base preflight held in any Mapping is read, as before. - Docs: - the 0.5 schema did accept the empty-plan payload (only 0.4 refused it); - "only verify authorizes merge" overstated it, since `check` also does, and the owner approved the AGENTS.md correction; - updated STABILITY's stable preflight fields, agent-recipes, mcp-server.md (drift still stops an empty plan), the instruction-structure note and ROADMAP's #610 status.
