From f9dfcf81a3bd64af80ae65b909bd0d08c4de9ba7 Mon Sep 17 00:00:00 2001 From: aorlov Date: Sat, 30 May 2026 03:48:03 +0200 Subject: [PATCH] fix(plan-engine): runtime block-identity self-heal on compile (SD-3283) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DOCUMENT_IDENTITY_CONFLICT was blocking every mutation on documents whose in-session ProseMirror state already carried duplicate paraId / sdBlockId values. The dominant production path is a Yjs collab restore: the import- time normalizer (`normalizeDuplicateBlockIdentitiesInContent`) runs only on fresh DOCX imports, so any duplicate that landed in the persisted Yjs state (whether copy-paste-cloned paraIds from Word's exporter, or older runtime splits before keepOnSplit:false shipped) survived every later hydration. The only recovery in production was "open in Word, re-save, re-upload" — and the legacy error message even told callers to invoke a `document.repair()` op that did not exist. This change makes `compilePlan` self-heal a corrupted in-session state before `assertNoDuplicateBlockIds` fires, using the same rename semantics the importer already applies. What landed: * New `plan-engine/repair-block-identities.ts` walks the PM doc, dispatches one transaction with per-attribute `tr.setNodeAttribute` renames (AttrStep, no from/to — explicitly skipped by structured-content lock and permission- ranges filters), then post-dispatch verifies the attrs actually applied; throws REPAIR_BLOCKED with offending IDs in the message string when a filter rejects it (Python SDK strips `details`). * `BlockIndex` carries an optional `explicitIdentities` side-channel populated during the existing `buildBlockIndex` descendants walk — the planner consumes it for O(1) clean-doc early-exit, no second walk. * `compilePlan` gains `CompilePlanOptions { skipIdentityRepair }`; `previewPlan` passes it so preview stays non-mutating and surfaces the conflict as a PreviewFailure via the existing PlanError catch. * The repair transaction is meta-tagged with `superdoc/block-identity-repair`. Both `trackRevisions` and the story-runtime host-store sync listener meta-skip it (placed before `docChanged` so a future metadata-only repair also stays revision-invisible), and `trackedTransaction` bypasses track-changes wrapping at an explicit check rather than the implicit disallowed-meta fall-through. * `executePlan` now calls `checkRevision` BEFORE `compilePlan` so a stale optimistic-concurrency request rejects without first letting the repair rewrite identity attrs. Regression test pins that the doc identity is unchanged and revision unmoved across a stale-revision rejection. * `assertNoDuplicateBlockIds` error message embeds the colliding IDs in the string (with per-ID + total-count truncation) and points remediation at `doc.open`, removing the dead `document.repair()` reference. * Importer normalizer (`normalizeDuplicateBlockIdentitiesInContent`) refactored to consume `getExplicitIdentityEntries` + `groupIdentityEntriesByValue` from the shared `block-identity-renaming.js` module; the repair module imports the same primitives. Single source of truth for "which attrs carry identity" across import-time and runtime. Coverage: * Unit: `repair-block-identities.test.ts` pins the fast-path early-exit, per-attribute setNodeAttribute, deterministic allocator ordering, and the REPAIR_BLOCKED throw on filter-rejected dispatch. * Regression: `tests/regression/duplicate-block-identities.test.js` exercises end-to-end recovery from a Yjs-restore-shaped state through compilePlan + executeCompiledPlan, previewPlan non-mutation, and stale-revision rejection before any repair mutation. * Track-changes: `revision-tracker.test.ts` pins the meta-skip ordering invariant (skip applies even for hypothetical metadata-only repair txs). * All affected suites green (180/180 in touched files; full super-editor suite ran clean during cross-review iterations).
