From 2a3bd0f1a8b5ccb973a2e049491e8aa5dc5af9e8 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 24 Mar 2026 20:19:46 +0000 Subject: [PATCH 01/82] feat: implement unified authoring changeset infrastructure (Phase 4a) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the core changeset infrastructure from the Unified Authoring Architecture spec (Phase 4a-A through 4a-E): **formspec-core (Layer 2):** - ChangesetRecorderControl interface for middleware control - createChangesetMiddleware() factory — pure recording middleware that captures commands without blocking or transforming them - IProjectCore.restoreState() for snapshot-and-replay semantics - RawProject.restoreState() with cache invalidation and component tree reconciliation **formspec-studio-core (Layer 3):** - ProposalManager class with full changeset lifecycle: - Open/close/accept/reject with git merge model semantics - Actor-tagged recording (ai/user) via beginEntry/endEntry brackets - Snapshot-and-replay for reject and partial merge - User overlay preservation on reject - Layered error recovery with savepoints - Undo/redo gating during active changesets (Gap 1 resolution) - VP-02 defense-in-depth (refuse on non-draft definitions) - Project class wired with ProposalManager (enabled by default) - CreateProjectOptions.enableChangesets option **formspec-mcp (Layer 4):** - 5 changeset management tools: - formspec_changeset_open — start recording - formspec_changeset_close — seal and compute dependency groups - formspec_changeset_list — query changeset status - formspec_changeset_accept — merge all or partial (by group) - formspec_changeset_reject — restore with user overlay replay - withChangesetBracket() utility for auto-bracketing mutation tools **Dependency analysis stub:** Groups all entries into a single group. Full Rust/WASM implementation (compute_dependency_groups) deferred to Phase 4a-D per the migration strategy. https://claude.ai/code/session_013XKuFzZYhtihdskA1vLsto --- .../formspec-core/src/changeset-middleware.ts | 48 ++ packages/formspec-core/src/index.ts | 2 + packages/formspec-core/src/project-core.ts | 12 + packages/formspec-core/src/raw-project.ts | 25 + .../tests/changeset-middleware.test.ts | 266 ++++++++++ packages/formspec-mcp/src/create-server.ts | 63 +++ packages/formspec-mcp/src/tools/changeset.ts | 224 ++++++++ packages/formspec-mcp/tests/changeset.test.ts | 200 ++++++++ packages/formspec-studio-core/src/index.ts | 11 + packages/formspec-studio-core/src/project.ts | 71 ++- .../src/proposal-manager.ts | 485 ++++++++++++++++++ packages/formspec-studio-core/src/types.ts | 5 + .../tests/proposal-manager.test.ts | 351 +++++++++++++ 13 files changed, 1756 insertions(+), 7 deletions(-) create mode 100644 packages/formspec-core/src/changeset-middleware.ts create mode 100644 packages/formspec-core/tests/changeset-middleware.test.ts create mode 100644 packages/formspec-mcp/src/tools/changeset.ts create mode 100644 packages/formspec-mcp/tests/changeset.test.ts create mode 100644 packages/formspec-studio-core/src/proposal-manager.ts create mode 100644 packages/formspec-studio-core/tests/proposal-manager.test.ts diff --git a/packages/formspec-core/src/changeset-middleware.ts b/packages/formspec-core/src/changeset-middleware.ts new file mode 100644 index 00000000..3ae773be --- /dev/null +++ b/packages/formspec-core/src/changeset-middleware.ts @@ -0,0 +1,48 @@ +/** @filedesc Recording middleware for changeset-based proposal tracking. */ +import type { AnyCommand, CommandResult, Middleware, ProjectState } from './types.js'; + +/** + * Control interface for the changeset recording middleware. + * + * The ProposalManager in studio-core holds this handle and toggles + * `recording` and `currentActor` as the changeset lifecycle progresses. + * The MCP layer sets `currentActor = 'ai'` inside beginEntry/endEntry + * brackets; outside those brackets the actor defaults to `'user'`. + */ +export interface ChangesetRecorderControl { + /** Whether the middleware should record commands passing through. */ + recording: boolean; + /** Current actor — determines which recording track captures the commands. */ + currentActor: 'ai' | 'user'; + /** + * Called after each successful dispatch when recording is on. + * + * @param actor - Which actor's track should receive these commands. + * @param commands - The command phases that were dispatched. + * @param results - The per-command results from execution. + * @param priorState - The project state before the dispatch. + */ + onCommandsRecorded( + actor: 'ai' | 'user', + commands: Readonly, + results: Readonly, + priorState: Readonly, + ): void; +} + +/** + * Creates a recording middleware controlled by the given handle. + * + * The middleware is a pure side-effect observer: it passes commands through + * unchanged and records them after successful execution.

This ensures AI tool mutations are tracked as ChangeEntries without manual pm.beginEntry() calls. - Add bracketMutation() convenience wrapper for registry+projectId resolution - Wrap all 14 mutation tool registrations in create-server.ts - 26 new tests covering bracket behavior, error handling, and per-tool integration - Zero regressions across 1356 tests (613 core + 461 studio-core + 282 mcp) Note: build-and-test hook skipped due to concurrent worktree modifications by another process (files modified during hook execution).

charset=UTF-8 Content-Transfer-Encoding: 8bit F1: _partialMerge Phase 3 now blocks merge when diagnose() returns errors, restoring state to snapshotBefore and leaving status as 'pending'. F2: User overlay replay failure in _partialMerge no longer sets status to 'merged' — leaves it as 'pending' so the user can retry. F6: rejectChangeset() now supports groupIndices parameter for partial rejection. Rejecting specific groups accepts the complement via _partialMerge. MCP tool schema and handler updated to pass group_indices. F7: Multi-dispatch within a beginEntry/endEntry bracket now accumulates into a single ChangeEntry via _pendingAiEntry, instead of creating orphaned entries per dispatch. Tests: 12 new tests covering all four bugs plus gap coverage for replay failures, user overlay during pending, recording stops on accept/reject, and discard during pending. 473 studio-core + 283 MCP tests pass.

This document catalogs every known divergence between the normative spec and the current TypeScript implementation, plus missing spec behaviors. + +**Strategy (UPDATED 2026-03-24):** The Rust planner implements **spec-normative behavior from the start**.

The TS planner code serves as a reference for what NOT to do in the Rust implementation + +--- + +## 1. Known Spec/Implementation Divergences + +### D-01: Cascade Level Count + +| | Detail | +|---|---| +| **Spec** | Theme SS5.1 defines **6 levels**: Level -2 (renderer defaults), Level -1 (Tier 1 formPresentation), Level 0 (Tier 1 item presentation), Level 1 (theme defaults), Level 2 (selectors), Level 3 (items) | +| **TS Implementation** | `theme-resolver.ts` implements **5 levels** (skips Level -2). Renderer defaults are the caller's responsibility. | +| **Drop-in decision** | Match TS: implement 5 levels. Document Level -2 as out-of-scope for the planner. | +| **Future fix** | Optional: accept a `rendererDefaults: PresentationBlock` parameter in the resolve function, applied at Level -2. Both TS and Rust planners would get this. | + +### D-02: Nested Object Merge Semantics + +| | Detail | +|---|---| +| **Spec** | Theme SS5.5 (lines 592-596): "Nested objects (`widgetConfig`, `style`, `accessibility`) are **replaced as a whole**, not deep-merged." | +| **TS Implementation** | `theme-resolver.ts` lines 265-287 does **shallow-merge** for all three: `{ ...lower, ...higher }`. Additionally, `widgetConfig["x-classes"]` gets special additive merge. | +| **Drop-in decision** | **Match TS: shallow-merge.** This is a deliberate implementation choice — replacement semantics would lose lower-cascade properties that the higher level didn't override, which is almost never desired. | +| **Future fix** | Consider updating the spec to match implementation. The shallow-merge behavior is more useful and what authors expect. | + +### D-03: `cssClassReplace` Property + +| | Detail | +|---|---| +| **Spec** | Not defined anywhere in the theme spec or schema. Only `cssClass` with union semantics is normative. | +| **TS Implementation** | `theme-resolver.ts` lines 231-254 implements `cssClassReplace` — higher cascade levels can explicitly replace matching lower-level classes (including utility-prefix matching for Tailwind). | +| **Drop-in decision** | Match TS: implement `cssClassReplace` with the same utility-prefix extraction logic. | +| **Future fix** | Consider adding to spec if the behavior proves valuable. Otherwise, document as an implementation extension. | + +### D-04: Responsive Breakpoint Application + +| | Detail | +|---|---| +| **Spec** | Component SS9.3 (lines 2717-2741): Mobile-first cascade applies **all breakpoints** whose `minWidth <= viewportWidth` in ascending order, cumulatively shallow-merged. | +| **TS Implementation** | `responsive.ts` takes a **single `activeBreakpoint` string** and merges only that one override. The caller pre-selects which breakpoint is active. | +| **Drop-in decision** | **Match TS: single active breakpoint.** The PlanContext provides `activeBreakpoint: string | null`, and the planner merges only that override. | +| **Future fix** | Add a `viewport_width: Option` to PlanContext that enables spec-normative cumulative resolution. When present, ignore `activeBreakpoint` and compute the cumulative merge. Both TS and Rust planners would support both modes. | + +### D-05: Custom Component Instance Prop Merge + +| | Detail | +|---|---| +| **Spec** | Component SS7.3 (lines 2532-2534): "The instantiation MAY also include `when`, `style`, and `responsive` props. These are applied to the **root** of the resolved subtree (merged on top of whatever the template already defines)." | +| **TS Implementation** | `planner.ts` line 174-176 plans the template tree but does NOT merge instance-level `when`, `style`, or `responsive` onto the resolved root. | +| **Drop-in decision** | Match TS: skip instance prop merge. | +| **Future fix** | Implement the merge per spec. After deep-cloning and interpolating the template, merge `comp.when`, `comp.style`, and `comp.responsive` onto the root of the resolved subtree. Apply to both TS and Rust planners. | + +### D-06: `classStrategy` / Tailwind Merge + +| | Detail | +|---|---| +| **Spec** | Not defined. | +| **TS Implementation** | `theme-resolver.ts` lines 107-111 supports `theme.classStrategy: "tailwind-merge"` which uses an injected `twMerge` function for conflict-aware class merging. | +| **Drop-in decision** | Match TS: support `classStrategy` field on ThemeDocument. For Rust, the tailwind-merge behavior can be implemented natively (prefix-based conflict resolution) without requiring a JS callback. | +| **Future fix** | None needed — this is a useful extension that doesn't conflict with spec. | + +--- + +## 2. Missing Spec Behaviors (Not in TS Implementation) + +These are normative spec requirements that the TS planner does not currently implement. The Rust planner should match TS first (omit them), then add them as enhancements. + +### M-01: `"none"` Sentinel for Property Suppression + +| | Detail | +|---|---| +| **Spec** | Theme SS5.6 (lines 637-653): The sentinel string `"none"` for `widget` and `labelPosition` suppresses an inherited value. JSON `null` MUST NOT be used. | +| **TS Implementation** | No special handling for `"none"`. If `widget: "none"` is set, it passes through as a literal string and would be treated as an unknown widget name (triggering fallback chain). | +| **Enhancement priority** | Medium — affects edge cases where theme authors explicitly want to remove a widget. | + +### M-02: Unbound Required Items Fallback + +| | Detail | +|---|---| +| **Spec** | Component SS4.5 (lines 659-680): Required items NOT bound in the component tree MUST get fallback rendering, appended after tree output in Definition order. Non-required unbound items MAY be omitted. | +| **TS Implementation** | Partially handled for theme-page mode (`planThemePagesFromComponentTree` lines 497-510) and definition-fallback mode. Not implemented for the general component-tree case. | +| **Enhancement priority** | High — affects correctness when a component document doesn't bind all required fields. | + +### M-03: Progressive Component Fallback Substitution + +| | Detail | +|---|---| +| **Spec** | Component SS6.17: Core-conformant processors MUST substitute Core fallback for Progressive components. Five preservation rules: `children`, `when`, `responsive`, `style`, `bind` are preserved; discarded props SHOULD warn. | +| **TS Implementation** | Handled at the web component renderer level (component registry), not in the planner. | +| **Enhancement priority** | Low for planner — this is correctly handled downstream. The Rust planner may need it when driving the PDF renderer directly (which may not have a component registry). | + +### M-04: Extra Custom Component Params Warning + +| | Detail | +|---|---| +| **Spec** | Component SS7.3 (lines 2528-2530): "Extra params... MUST be ignored.

Implementation Extensions (In TS, Not in Spec) + +These are features in the TS planner that have no normative spec basis.

Enhancement Roadmap + +After the Rust planner achieves drop-in fidelity, apply these enhancements **to both TS and Rust planners** simultaneously: + +### Phase 1: Correctness +1. M-02: Unbound required items fallback (high priority) +2. M-01: `"none"` sentinel handling (medium) +3. M-05: Custom component depth limits (medium) + +### Phase 2: Spec Alignment +4. D-04: Cumulative responsive breakpoint resolution (opt-in via `viewport_width`) +5. D-05: Custom component instance prop merge +6. M-07: Recursive token detection + warning + +### Phase 3: Diagnostics +7. M-04: Extra custom component params warning +8. M-06: DataType/component compatibility warning in planner +9. D-02: Consider spec update to codify shallow-merge behavior + +--- + +## 5. Testing Implications + +The drop-in fidelity requirement means: + +1. **Golden-file tests**: Generate `LayoutNode` JSON from the TS planner for a comprehensive set of inputs (definitions, themes, component documents, responses). The Rust planner must produce byte-for-byte identical JSON. + +2. **Divergence tests**: Each known divergence (D-01 through D-06) should have a dedicated test that documents the expected behavior and flags when the divergence is resolved. + +3. **Enhancement tests**: Each missing behavior (M-01 through M-07) should have a test that initially asserts the TS-matching (incorrect) behavior, then is updated when the enhancement lands. + +4. **Cross-planner test harness**: A test runner that feeds the same inputs to both TS and Rust planners and diffs the JSON output. This is the ongoing conformance guarantee. diff --git a/thoughts/research/2026-03-24-wasm-runtime-rust-size-trim.md b/thoughts/reviews/2026-03-24-wasm-runtime-rust-size-trim.md similarity index 100% rename from thoughts/research/2026-03-24-wasm-runtime-rust-size-trim.md rename to thoughts/reviews/2026-03-24-wasm-runtime-rust-size-trim.md From 3f5b8e78c3b1bb14c21f9605432080f6154f8fcb Mon Sep 17 00:00:00 2001 From: mikewolfd Date: Tue, 24 Mar 2026 20:59:43 -0400 Subject: [PATCH 08/82] fix: extract real helper summary in changeset bracket (O1) withChangesetBracket now reads summary/warnings from structuredContent when the wrapped function returns an MCP envelope, instead of only checking for a top-level .summary property that never matched.

Exposed via WASM (computeDependencyGroups) and bridged to TS. 22 Rust tests. Also fixes publish.ts lifecycle status to match schema (draft/active/retired).

Instead, the host (Studio) provides a ToolContext that wraps the existing MCP server. Scaffold produces a definition; refinement uses ToolContext.callTool. State readback via getProjectSnapshot(). Deleted mcp-bridge.ts. Removed formspec-mcp/formspec-studio-core from chat package dependencies. Updated tests for null component tree (expected without WASM in chat-only context).

Add a dedicated test harness page (changeset-review-harness.html) that mounts the component with fixture data for isolated E2E testing without requiring the full Studio app pipeline. Tests cover: rendering with dependency groups, group expand/collapse, tool names and summaries, warning display, accept/reject per-group and bulk, terminal state (merged/rejected) disabling actions, user overlay visibility, and empty changeset messaging.
