Use one canonical digest for minted and applied definitions.
validateSubgraphDefinition accepts non-reserved __ metadata. mintDefinition stores it, but projectDefinition removes it. Therefore, a minted definition can have a fallback digest different from the raw digest stored by define_subgraph.
For example, the projected digest can be 3a0b…23eb3, while the raw digest is 5f1b…5561. A valid competing definition with digest 5632…a1496 causes the minted replica to replace the definition while the define_subgraph replica returns "no-op". The replicas then contain different definitions.
Record the canonical digest when mint() stores each definition, or derive the fallback digest from the same canonical representation used for the submitted definition.

Use the same recursive definition set for alias uniqueness.
resolveDefinition searches root and nested definitions, but definitionAliases counts sameName only among root definitions. When a root and nested definition share a name, the root still receives that name as an alias when a catalog is available and the name is not a node class. countDefinitionInstances then counts nodes typed with that alias recursively. An ID-based interior write can be rejected as shared_definition_unforked, while a node typed with the ambiguous name fails with not_a_subgraph. Count sameName over the same recursive definition set as resolveDefinition to keep the KA-1 guard consistent.

Rejection tests must assert the document state, and one must pin abort-remainder.
Several rejection tests assert only the failure code: lines 79-82, 473-474, 485, 572, and 628. Lines 497-501 and 522-523 use the projection as the oracle. project() renders neither __stamps nor __applied, so a write into either is invisible to it while the document has really diverged.
Add byte identity under Y.encodeStateAsUpdate plus the absence of the op_id from __applied to each of those tests, in the form already used at lines 417-419 and 592-596. Also add one case where a valid op follows a rejected op in the same batch and does not apply. The existing suffix tests at lines 151-159 and 384-395 follow a no-op, not a rejection, so abort-remainder after a rejection is unpinned.

Stamp assertions dropped the key these tests own. Both lines now assert only Object.values(readStamps(doc)), so the stamp key is unchecked. The key is what carries the incarnation qualifier and the canonical owner that this PR changes, so both expectations would still pass if the key regressed.

Two carried review obligations still fail on this published head: delete/edit ordering and catalog-name collisions. Four others have passing focused evidence. Keep this replacement draft. Full context for agent readersVerified the published head using an isolated source archive and real applyOps/mint/project exports: 13 focused tests passed, 2 failed; typecheck passed. Five unpublished local fix files were not used as evidence for this head.
Passing source-specific cases cover unknown and nested widgets, shared first-hop paths longer than two segments, all three reserved fields plus missing/duplicate node IDs, and the same define/add set in both orders. These are scoped tests, not blanket closure of the original threads. Final reproducer and logs are retained in the owner's private recovery archive, Glossary: UUID = structured unique identifier; batch suffix = operations after the tested operation in one batch; retained definition = subgraph data still present after its instance is removed. |

Correction to the earlier test report: its reversed same-actor sequence violated causal order. A valid concurrent case still fails. Catalog collision fix verified locally; this published draft is unchanged. Full context for agent readersThe earlier 13-pass/2-fail result remains a historical measurement, but its delete/edit comparison was not valid convergence evidence. Reversing operations created sequentially by one actor reverses that producer's causal order. The corrected case uses two independent producers starting from one snapshot frontier of 2. Both tick to logical counter 3, with different actors and operation IDs. One deletes the UUID-named root instance; the other writes its interior widget from 1 to 7. In both legal arrival orders the instance disappears, but the retained definition projects as 1 versus 7. This reproduces on both the published head and its parent, so the latest commit did not introduce it. It also reproduces with the preserved five local fix files and the new catalog guard. The original delete-wins/batch finding concerned an unwanted rejection and aborted batch suffix; those specific checks pass. The retained-definition mismatch is a separate consequence of instance-addressed writes changing the backing definition. The deterministic-projection invariant requires equality, but the reviewed contract does not explicitly select whether the retained value should be 1 or 7. No rollback, tombstone, schema, or transport change has been inferred from this test. This tests independent semantic-op replay, not divergence in the current single-host-to-follower transport. The original catalog-class collision finding now has a local fix: recursively reject definition IDs that are own keys of the pinned catalog before mutation. New top-level and nested rejection tests failed before the fix and pass afterward; they assert unchanged document bytes and an unconsumed operation ID. A distinct definition remains accepted. Worker verification: 1,051 permanent-suite tests and complete types passed. Coordinator verification: 59 definition tests and the offline citation-pin gate passed; the separate valid concurrent probe still fails. This is not a fully verified replacement or browser acceptance claim. The two-file additive fix is preserved on top of the existing five-file local delta; none of that earlier work was overwritten. It has not been pushed to this PR. Original authors, reviewed refs, comments, and historical approvals remain at their source links; approvals do not transfer. Private reproducers and logs remain private. No source retirement, release, or deployment. Glossary: causal order = preserving each producer's observed sequence; logical counter = producer-owned ordering value; UUID = structured unique identifier; retained definition = subgraph template remaining after its instance is removed. |

Full context for agent readers
Scope and correction
The initial title/body described only the final alias commit. The actual main-relative change spans 13 files:
define_subgraphoperation/types/application, definition minting/projection, recursive edit preservation, trace/stamp support, README and regression/permutation tests. The coordinator corrected that incomplete description and marked this PR draft. It was published by a recovery worker before coordinator publication review.Source inputs include frontend definition PR 17454 and the necessary recursive restoration correction from frontend insertion PR 17501. The insertion operation and frontend adapters remain separate work. Neither source PR is retired or approved by this replacement. CMP means the standalone
comfy-multi-playerpackage; frontend consolidation remains deferred.Behavior and verification
Definition IDs are UUID-only. UUID-shaped instance types may arrive before definitions. Existing candidate behavior chooses the larger canonical SHA-256 content digest for competing definitions and preserves stamped interior widget edits. This conflict-selection rule is a proposal whose owner provenance is not yet established, not an accepted policy merely because tests pass.
The latest fix gives definition-ID and instance-ID widget paths one conflict register based on the final owning definition and node. Nested and direct paths to the same leaf converge; equal leaf IDs in distinct definitions remain isolated. Direct definition heads remain ID-only. Public op-only
writeTargetis unchanged. LWW means last-writer-wins operation ordering.Worker verification on the current head: complete typecheck and 1,043 tests passed. Coordinator inspected the diff and independently reran 56 focused definition/incarnation tests successfully. Hosted checks and actual review are separate gates; status-only success is not a completed review. No browser, packed-consumer, or deployment claim is made.
Carried review obligations
The preserved 82-record definition candidate map still requires current-head anchor refresh and final per-record dispositions. Earlier records, authors, dates, reviewed references, and source links remain preserved privately. No historical approval or QA result is represented as newly executed or as authority to merge this PR.
Required before readiness
SCHEMA_VERSIONis still 2; legacy path keys can coexist and are not consulted by the new canonical gate. Green fresh-document tests do not prove safe mixed-reader or pre-existing-document behavior. Private-alpha policy rules out adding a compatibility migration as the default answer.
