From 587591f93b0454f7a4f77f4f98a241c8238507ba Mon Sep 17 00:00:00 2001 From: Cristhofer Pincetti Date: Sat, 3 Oct 2026 16:41:34 -0300 Subject: [PATCH 1/8] feat(core): read stored records tolerantly and add the claude_code host Records written by a newer runtime may carry keys an older reader does not know. Strict record schemas rejected them as recovery_required, so one additive field would brick every older host reading the same store (D17). Reads now drop exactly the keys zod reports as unrecognized and parse again; any other violation still fails, and writes stay strict. hostSchema gains claude_code so the Claude Code adapter does not need to touch the task contract.

Hosts only parse native payloads and render decisions. Parsers ignore unknown keys and check only the keys a mapping needs. A pre-tool parse failure denies only on hosts whose descriptor is fail-closed; other events fail open with a diagnostic. Each host declares a descriptor of what it supports, with citations. capabilitiesFor derives engine capabilities from it; an undocumented axis never backs an enforced capability. session-context moves to hooks/context with one unfinished-task offer and session predicate.

The Codex hook is now a thin mapping onto core/hooks: unknown keys are ignored and a broken payload passes through with a stderr diagnostic. Pi and OpenCode take branch policy, session context, the unfinished-task offer, and their capabilities from core/hooks and their descriptors. The capability arrays are unchanged.

It now maps onto core/hooks and denies direct branch creation onto a protected or noncompliant name with exit 2, like the other hosts. subagentStart keeps its Cursor-only worker assignment path. Hook bundles now import core/hooks and direct modules instead of the core barrel, and a test pins that they load no doctor or setup code.

Records may now list such paths in a top-level critical array: a reader that would strip one fails with the upgrade message, so it neither acts on nor rewrites the record. Recovery copies a snapshot back verbatim, so it refuses any record it could only read by dropping fields. Under a plain union, stripping now keeps the branch that drops the fewest keys instead of the first that parses, so a key one branch knows is never lost. The design records the rule for new fields and the Claude PowerShell matcher, and a follow-up to verify Cursor's allow live.

Older hosts read the same store (OpenCode `@latest`, cached Cursor npx), and a new optional field in `evidenceSchema` makes them fail with `recovery_required`. S8 must ship reader tolerance (strip unknown keys on read, strict on write) **one release before** S9 writes new fields. Alternatively, release S8 and S9 in the same version and accept the window. | **Rule (S8a):** a new record field must be safe for an older reader to ignore and to lose on rewrite, **or** the writer lists its path in the record's top-level `critical` array; a reader that would strip a critical path fails closed with the upgrade message and never rewrites the record. Recovery never writes back a record it had to strip. | 8 | `pr status` via gh porcelain | Local gh is **2.45.0**, and its `gh pr checks` has **no `--json`**. Use `gh api graphql` / `gh api` and `glab api` only. This matches the existing code (`remoteBranchTip`, `mergedBranch`) and does not depend on the CLI version. | | 9 | Stack land: "PR 3 is retargeted" | With squash merges, retargeting **forces a restack**: `git rebase --onto `, then push `--force-with-lease`. That changes the head SHA and re-triggers CI. Patch-id carry-over keeps the *verdict*, not CI. Only a merge-commit strategy can retarget without a restack. | | 10 | Codex adapter is reusable for Claude | `parseCodexHookInput` rejects **unknown keys** and denies `PreToolUse` on a parse error. A Codex release that adds a field would therefore deny every tool call (a latent bug). Claude sends extra keys (`prompt_id`, `agent_id`, `agent_type`, `mcp_server`, …). All parsers must be lenient on unknown keys and strict only on required ones. | -| 11 | Cursor hooks are fine | Every Cursor hook spawns `npx -y --prefer-online …@latest` per event, so there is a registry round-trip on each shell command.
