From f9c2e6b11c884e6814790d7f666c4e2cce3a67be Mon Sep 17 00:00:00 2001 From: mchwang Date: Mon, 12 Oct 2026 09:24:56 -0700 Subject: [PATCH] Load plan schemas through the registry and close #6 Every version in schema/versions.json is now compiled from its retained snapshots, and plans and edit replies are checked by the version they declare. The loader refuses a registry that disagrees with the snapshots or validators, and treats a version with no validator as unsupported. Pin the released v1 files by SHA-256, keep them LF on checkout, and add the remaining #6 tests: path identity and Git mode mapping, hostile text in every authoring prompt, and output limits at the exact byte. Runtime gaps move to #162-#166.

It now builds every version from `schema/versions.json`: + +- Each registry entry names a plan path and an edit path. Each path must be a retained snapshot whose `$id` equals its path. No path may be named twice. All registry-named snapshots compile into one validator, so each `$id` is registered once. +- Each validator key maps to an implementation and the semantics document it implements. A registry entry that pairs a key with a different document is refused at load, and so is a key or implementation that another version already uses. A key with no implementation loads, and that version validates as unsupported (`docs/plan-format.md`: "Treat a missing validator implementation as unsupported"). +- A plan or edit reply is checked by the schema of the version it declares. `validatePlan` selects the version once and uses that selection for both the shape check and the semantic validator. The v1 validator also calls the module's `assertPlan`, which repeats the shape check through the production registry, not through a loader a test injects. A value with no registered version is checked by the current schema, so the error names `/schema_version` as before. +- `assertPlan` also refuses a version with no validator implementation. So do the paths that skip the semantic validator: `validateContinuationPlan` when every item is complete (it still checks the completed prefix, IDs, dependencies and the selected issue), and the store's check of a ready draft (`runner/store.ts`). `assertEditReply` refuses it in the same way, so the store does not mark such a reply ready. +- Imports, including provider drafts, must be in the current version: no migrations exist yet. The store's check of a ready draft (`runner/store.ts`) skips the semantic validator; it relies on the draft having passed `importPlan` when the planning author validated it, and the draft is imported again on Apply. +- A suggestion's edit reply must declare the same version as the plan it edits. The provider gets the edit schema of the previous plan's version. The suggestion binding cannot catch a mismatch, because the store builds its `schemaVersion` from the current plan (`runner/store.ts`), so this check in `applySuggestion` is the guard for each card. A reply with no cards never reaches it; it has nothing to apply. +- A new draft's provider gets the current version's plan schema. + +Each snapshot must require `schema_version` and allow only its own version, stated at its top level as `required` and a one-value `enum`, or the loader refuses it. A plan snapshot must also require `items` and not `edits`, and an edit snapshot the reverse, so an entry cannot swap the two. Selection relies on this. + +The loader compiles each snapshot as it reaches it. The v1 snapshots use only local `#/$defs` references. A future snapshot that refers to another snapshot must have that snapshot added to the validator before it is compiled. + +While v1 is the only registered version, every module-level path selects v1, and the v1 schema refuses any other `schema_version`. So no test can yet tell these from a version-blind implementation: + +- `assertPlan` and `assertEditReply` selecting by declared version; +- imports required to be in the current version; +- an edit reply required to match its plan's version; +- the suggestion provider getting the previous plan's edit schema; +- a new draft's provider getting the current version's plan schema; +- `validateContinuationPlan` with every item complete, and the store's check of a ready draft, refusing a version with no validator (tested through the loader's `assertPlan` only). + +`test/schema-versions.test.ts` tests selection and validation through an injected two-version loader. The change that registers a second version must add module-level tests for the paths above. Selection, Ajv and the semantic validator each read `schema_version` separately. Every caller passes parsed or stored data today, but a second version should select once and pass the selection on. + +Unversioned CLI copies are never registered: the loader compiles only the snapshots registry paths name. `test/schema-versions.test.ts` loads the registry with the copies available beside the snapshots and checks that they are not compiled. `test/registry.test.ts` checks that the copies equal the current snapshots byte for byte. + +Some code stays v1 whatever version a plan declares. A second version that changes these would also need them selected through the registry: + +- the JSON/YAML parser (`core/parse-v1.ts`); +- the edit operations and payload rules in `applySuggestion`, and `validateContinuationPlan`; +- the Plans screen, which checks `schema_version === 1` (`web/public/app.js`); +- the `Plan` and `EditReply` types, whose `schema_version` is the literal `1` (`core/plan.ts`). + +A load error is a defect in the build: it throws when the module loads, so the server does not start. A validator key with no implementation is not a load error: the server starts and every plan in that version is refused as unsupported. `test/registry.test.ts` checks that each version's key is `v`. + +## Retained file digests + +`test/schema-versions.test.ts` pins the SHA-256 of every file a registry entry names, and checks that the pinned set equals the named set. Editing a released snapshot or its semantics document fails the test. Adding a version without pinning its files also fails. + +## Test evidence + +Each break below was made on purpose, one at a time, and made the named tests fail. The code was restored afterwards.
