Shared ingestion code in `gitnexus/src/core/ingestion/` must not name languages — use `LanguageProvider` hooks (see `AGENTS.md` and `ARCHITECTURE.md` § Call-Resolution DAG). +- [ ] No hidden cross-phase coupling; no leaking of language-specific logic into shared infrastructure without a documented architectural reason. +- [ ] Runtime and graph behavior are consistent — the real source of truth is fixed at the source, not symptom-patched in a downstream layer. +- [ ] Direct imports from `gitnexus-shared` are used. No barrel re-exports introduced to paper over drift between packages. + +### 2.3 Design and Readability + +- [ ] The implementation is the **smallest correct solution** for the requirement. No speculative abstraction, unnecessary indirection, clever but hard-to-follow control flow, or unrelated cleanup. +- [ ] Naming, control flow, ownership, and extension points are clear enough that the next contributor can extend the code without archaeology. +- [ ] Comments are minimal and useful — they explain intent, invariants, contracts, or non-obvious constraints. No stale comments, placeholder comments, narrated code, commented-out code, or "what" comments where a good name would do. +- [ ] No copy-paste duplication created for convenience; no premature deduplication of three similar lines. + +### 2.4 Contracts and Compatibility + +- [ ] Existing contracts (types in `gitnexus-shared/`, CLI flags, MCP tools/resources, HTTP routes, graph node/edge shapes, persisted IDs) are preserved unless the task explicitly requires a contract change. +- [ ] Any contract change is intentional, explicit, and reflected in **every direct consumer** in the same change, with types aligned end-to-end. +- [ ] Persisted data changes (graph schema, IDs, embeddings) are backward-compatible or accompanied by a documented migration / reindex path. +- [ ] If user-visible behavior, public usage, CLI help, or README examples change, the relevant docs, examples, help text, or migration notes are updated in the same change. + +### 2.5 Security + +- [ ] No new injection surfaces (command, path, SQL/Cypher-style, prompt) introduced on paths that consume untrusted input. +- [ ] No secrets, tokens, or credentials committed to the repo, to logs, or to error messages. +- [ ] Filesystem access honors the repo-scope and indexed-repo boundaries documented in `AGENTS.md` and `GUARDRAILS.md`. +- [ ] Third-party dependencies added or bumped are justified, from reputable sources, and do not regress the supply-chain posture. + +### 2.6 Performance and Resource Use + +- [ ] No repeated avoidable work, unnecessary scans, unnecessary round-trips, unbounded caches, or obvious hot-path regressions. +- [ ] Tree-sitter buffer sizing follows the adaptive 512KB–32MB convention (`getTreeSitterBufferSize`) — do not hard-code new buffer sizes. +- [ ] Memory and handle lifecycles are explicit: database handles (LadybugDB) close cleanly, no dangling process watchers, no leaked tree-sitter parsers. +- [ ] Long-running or large-graph paths remain bounded or are measurably streamed; degradation on large real repos is considered, not assumed benign. + +### 2.7 Tests + +- [ ] Tests cover the **real changed path** — they would fail if behavior, wiring, or contracts were broken, not only if a mock were misconfigured. +- [ ] Integration tests hit a real database where the production path does; do not introduce mocks that hide migration or schema drift. +- [ ] Assertions are meaningful. Use `toBe` / `toEqual` for exact expectations; avoid `toBeGreaterThanOrEqual` and other bounds-only assertions that mask regressions. +- [ ] Fixtures are realistic enough for the risk of the change — a one-file fixture is not sufficient for a pipeline-wide behavior change. +- [ ] New tests are deterministic and do not depend on network, clock, or host-specific paths without explicit isolation. + +### 2.8 Observability and Operability + +- [ ] Errors surfaced to users or callers are actionable: they name what failed, what input was involved (without leaking secrets), and how to recover where possible. +- [ ] Logging is proportionate — no noisy debug logs left in hot paths, no silent catches that swallow diagnostics. +- [ ] CLI exit codes and MCP tool responses are correct for each outcome (success, user error, internal error). +- [ ] Progress reporting (`PipelineProgress` and similar shared contracts) remains accurate after the change. + +### 2.9 Reversibility and Risk + +- [ ] The change has a clear rollback story: revert is safe, or migration is accompanied by a documented rollback / reindex procedure. +- [ ] Residual risks, compatibility impacts, and operational concerns are either resolved or **clearly stated** in the PR description. +- [ ] Destructive or hard-to-reverse operations (graph rebuild, schema change, `git` state manipulation) are opt-in or guarded. + +## 3. Agent-Assisted Workflow Guardrails + +When the change is produced with or reviewed by an AI agent, the following additional gates apply: + +- [ ] **Scope match.** The final diff matches the intended symbols, files, and processes — no speculative refactors, unrelated formatting churn, or collateral edits outside the task scope. +- [ ] **Evidence-based edits.** Claims about repo state are verified against the current code, not trusted from memory or stale documentation. +- [ ] **Impact analysis.** Where GitNexus graph tooling is available and relevant, impact of non-trivial symbol, contract, or runtime-path changes is checked **before** editing. +- [ ] **Embeddings preserved.** If an indexed repo already has embeddings and re-analysis is required, embeddings are preserved — not accidentally dropped by a destructive reindex. +- [ ] **No false-done.** "Done" is claimed only after the Validation Baseline below has been run or any gap is explicitly named. Green tests on an unrelated path do not constitute validation. +- [ ] **Five-axis self-review** before handing off: correctness, readability, architecture, security, performance. + +## 4. Validation Baseline + +Run the commands relevant to the touched area. If something cannot be run in the current environment, state it explicitly in the handoff. + +### 4.1 Build ordering + +- [ ] `gitnexus-shared/` dist is built before consuming packages are typechecked or tested (CI uses the `setup-gitnexus` action for this — local runs must match). + +### 4.2 If `gitnexus/` changed + +- [ ] `cd gitnexus && npx tsc --noEmit` +- [ ] `cd gitnexus && npm test` +- [ ] `cd gitnexus && npx prettier --check .` for files in the diff (pre-commit runs the affected-tests subset; do not expand scope) + +### 4.3 If `gitnexus-web/` changed + +- [ ] `cd gitnexus-web && npx tsc -b --noEmit` +- [ ] `cd gitnexus-web && npm test` +- [ ] `cd gitnexus-web && npm run test:e2e` when browser flows or user-facing UI behavior changed + +### 4.4 If `gitnexus-shared/` changed + +- [ ] Shared package builds cleanly (`npm run build` in `gitnexus-shared/`) +- [ ] Dependent packages still typecheck and test after the shared change — verify both CLI and web consumers together + +### 4.5 If CI workflows or release pipelines changed + +- [ ] The workflow passes a dry-run or triggered run before merge; concurrency (`cancel-in-progress`) and the `setup-gitnexus` action remain wired correctly. +- [ ] `CHANGELOG.md` is **not** edited here — it is owned by the release process. + +## 5. Review Gates + +A reviewer (human or agent) should be able to answer **yes** to each of the following before approving: + +1. **Correctness** — Does the change do what it claims on the real runtime path? +2. **Readability** — Will the next contributor understand this in six months without asking? +3. **Architecture** — Is it in the right package, layer, and phase? Are boundaries respected? +4. **Security** — No new injection, leak, or trust-boundary violation? +5. **Performance** — No obvious regression on realistic inputs? +6. **Tests** — Would a regression in the changed behavior fail loudly? +7. **Scope** — Does the diff match the intended change, with no unrelated churn? + +## 6. "Not Done" Signals + +A change is **not** Done if any of the following is true, even if CI is green: + +- The runtime path is not actually exercised by the tests. +- A contract drifted between `gitnexus/`, `gitnexus-web/`, and `gitnexus-shared/` and only one side was updated. +- A language-specific concern leaked into shared ingestion code. +- The diff contains unrelated reformatting, refactors, or cleanup beyond the stated task. +- Logs, comments, or TODOs were added as placeholders for work not done. +- The change depends on a manual step that is not documented. +- `CHANGELOG.md` was edited during PR work. +- Pre-commit, prettier, or typecheck was bypassed without explicit justification. + +## 7. Task-Specific DoD Template + +Use this in implementation and review prompts. Keep it short and tailor it to the actual change: + +```md +# Definition of Done for this implementation + +- [ ] Runtime wiring is complete for the affected path. +- [ ] Requested behavior is correct and relevant contracts are preserved or explicitly updated. +- [ ] The design stays scoped, readable, and proportionate to the task. +- [ ] Tests prove the changed behavior and catch broken wiring. +- [ ] Required validation for touched packages has been run, or any gap is explicitly noted. +- [ ] Repo boundaries, security, performance, and operational safety are respected. +- [ ] The diff contains only the intended change — no unrelated churn. +``` + +## 8. How to Use This File in Claude Review + +Reference this file as the repo-wide completion bar. Add a task-specific review instruction such as: + +```md +Review this change against `DoD.md` and the repo docs (`AGENTS.md`, `GUARDRAILS.md`, +`CONTRIBUTING.md`, `TESTING.md`, `ARCHITECTURE.md`). Treat `DoD.md` as the minimum +bar for production readiness. Flag anything that is partially wired, contract-unsafe, +under-tested, architecturally misplaced, scope-creeping, or harder to maintain than +necessary. Apply the five-axis review gate: correctness, readability, architecture, +security, performance. +``` + +## 9. Evolution + +This DoD is living. Revisit it when: + +- A class of incident slips past it (add a gate). +- A gate becomes consistently ceremonial without catching issues (remove or merge it). +- The architecture evolves in a way that changes what "done" means (update placement, validation, or contracts sections). + +Track material updates in the changelog below.

GitNexus indexes each repo independently, then a _group_ stitches the per-repo indexes into a single cross-repo view that the `impact`, `query`, and `context` tools can traverse. If your services live in one monorepo, much of this still applies — set each service as a member of a group and use the `service` prefix to scope queries — but the walkthrough assumes the harder multi-repo case. + +## Mental model + +- Each repository has its own `.gitnexus/` index (a LadybugDB graph of symbols, relationships, processes). `gitnexus analyze` in each repo produces that index completely independently. +- A **group** is a higher-level construct stored at `~/.gitnexus/groups//` that references the per-repo indexes by their registry name. +- Sync-time extractors walk each member repo and emit **contracts** — provider or consumer records keyed by a canonical `contractId` (`grpc::auth.AuthService/Login`, `http::GET::/orders`, etc.). +- The sync step matches providers and consumers that share a `contractId` and writes **cross-links** to `/contracts.json`. Those cross-links are what lets `impact({repo: "@", target: "X"})` hop from one repo into another. +- Contracts come from three places: automatic contract extractors (`grpc-extractor`, `http-route-extractor`, `topic-extractor`), a manifest escape hatch (`config.links` in `group.yaml`), and — for same-name symbol matches where no contract is declared — the exact-match matching cascade in [`matching.ts`](../../gitnexus/src/core/group/matching.ts). +- Each repo stays editable and re-indexable on its own. Re-run `gitnexus analyze` in a repo when it changes, then `gitnexus group sync ` to refresh `contracts.json`. `gitnexus group status` reports which members are stale. + +## Prerequisites + +- GitNexus installed and runnable as `gitnexus` or `npx gitnexus` (see the root [README.md](../../README.md)). +- Each service repository checked out locally.

The parser rejects anything else. +- `name` — required; used for the group directory name and all CLI / MCP calls. +- `repos` — a mapping from **group path** (a logical name you choose; can be a hierarchy like `backend/orders`) to **registry name** (the name shown by `npx gitnexus list`). Both sides appear throughout the tooling: contract rows use the group path; `@/` routes tools to a single member. +- `links` — optional manifest escape hatch, one entry per explicit cross-repo contract. Validated by the parser: `from` and `to` must be known repo paths, `type` must be one of `http | grpc | topic | lib | custom`, and `role` must be `provider | consumer`. +- `detect` — toggles per extractor family. Defaults (set in `config-parser.ts`) turn `http`, `grpc`, `topics`, and `shared_libs` on; disable the ones you don't use to speed up sync. +- `matching` — thresholds for the matching cascade.

Each RPC method becomes a provider contract with `contractId = grpc::./` and `confidence = 0.85`. Parsing uses the vendored `tree-sitter-proto` grammar when available and falls back to a length-preserving manual parser (`extractServiceBlocks`) otherwise, so `.proto` extraction works on platforms where the grammar fails to build. +2. **Source scan.** Every source file whose extension matches [`GRPC_SCAN_GLOB`](../../gitnexus/src/core/group/extractors/grpc-patterns/index.ts) is parsed by its language plugin: + +| Language | Provider signal | Consumer signal | +|----------|-----------------|-----------------| +| Go ([`go.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/go.ts)) | `pb.RegisterXxxServer(...)`, `pb.UnimplementedXxxServer` embedded in struct | `pb.NewXxxClient(conn)` | +| Java ([`java.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/java.ts)) | `extends XxxServiceGrpc.XxxServiceImplBase` (with or without `@GrpcService`) | `XxxServiceGrpc.newBlockingStub(...)`, `newStub(...)` | +| Python ([`python.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/python.ts)) | `add_XxxServicer_to_server(...)` (bare or `_pb2_grpc.` attribute form) | `XxxStub(channel)` (ignores `Mock`/`Test`/`Fake`/`Stub`) | +| Node / TS ([`node.ts`](../../gitnexus/src/core/group/extractors/grpc-patterns/node.ts)) | NestJS `@GrpcMethod('Service','Method')` | `@GrpcClient` field typed `XxxServiceClient`, `client.getService('Service')`, `new XxxServiceClient(...)`, `new foo.bar.XxxService(...)` in files that call `loadPackageDefinition` | + +For each source-scan detection the extractor looks up the short service name in the proto map and picks: + +- `grpc::./` when a method is named and the service resolves against the proto map, +- `grpc::./*` (wildcard) when only the service is known, or +- `grpc::/*` when no `.proto` is available at all. + +Provider detections land at confidence 0.8 (with proto) or 0.65 (without); consumers at 0.75 or 0.55. NestJS `@GrpcMethod` is fixed at 0.8 because the decorator is self-describing. + +### Matching + +`matching.ts` lowercases the package/service segment before comparing contract ids, so bindings that capitalize names differently (`auth.AuthService` vs `auth.authservice`) still match. Method names are compared case-sensitively because gRPC's wire path is case-sensitive. Service-only wildcards (`grpc::pkg.Svc/*`) match any method on the same service during cross-linking. + +### Known limitations + +- **Ambiguous proto resolution.** If a short service name exists in more than one `.proto` file and the source-scan hit can't be narrowed down by shared directory segments (`resolveProtoConflict` refuses to guess), the extractor skips contract emission and logs a warning. +- **Proto packages must be resolvable locally.** Transitive imports that point outside the repo produce an empty package segment, which means the contract id collapses to `grpc::/`. Cross-repo matches still work as long as both sides agree on the empty package. +- **Rewrite rules are not implemented.** If the provider repo writes `grpc::orders.OrderService/PlaceOrder` and the consumer repo writes `grpc::orderspb.OrderService/PlaceOrder`, they won't cross-link automatically. Use `config.links` to declare the correspondence (see below). +- **One sync = one snapshot.** Contracts are extracted against the indexed snapshot of each repo. Re-index first, then re-sync; the `status` command and resource surface staleness. + +## When automatic extraction isn't enough + +The escape hatch is the `links` list in `group.yaml`, handled by [`ManifestExtractor`](../../gitnexus/src/core/group/extractors/manifest-extractor.ts). Each entry is a **one-directional** provider/consumer declaration: + +```yaml +version: 1 +name: payments-platform +repos: + gateway: gateway + orders: orders + inventory: inventory + +links: + # Explicit gRPC method: use when naming mismatches stop the + # automatic matcher from cross-linking. + - from: gateway + to: orders + type: grpc + contract: OrderService/PlaceOrder + role: consumer + + # Service-level link when you don't want to enumerate methods. + - from: orders + to: inventory + type: grpc + contract: InventoryService + role: consumer + + # Works for HTTP too — use `METHOD::/path` form for the exact + # handler, or just `/path` for a method-agnostic wildcard. + - from: gateway + to: orders + type: http + contract: POST::/orders + role: consumer +``` + +What the manifest extractor does (see [`manifest-extractor.ts`](../../gitnexus/src/core/group/extractors/manifest-extractor.ts)): + +1. Builds a canonical `contractId` with `buildContractId` — the same canonicalization used by the automatic extractors, so manifest links cross-match automatic contracts on the other side. +2. Tries to resolve each side to a real graph symbol (the `Route` node for HTTP, a `Function|Method` / `Class|Interface` for gRPC, a `Package|Module` for `lib`). +3. If resolution fails, falls back to a deterministic synthetic uid (`manifest::::`) so both sides still line up in cross-impact — name-only links still work when the symbol isn't in the graph. +4. Emits both a provider and a consumer `StoredContract` (confidence `1.0`, `source: "manifest"`) and a `CrossLink` with `matchType: "manifest"`. + +Use `links` for exactly the cases the extractor can't infer: different package names across repos (see #701), hand-rolled transports, cases where the provider repo isn't checked out locally but you still want a record, or any contract whose provider and consumer simply don't share a surface the extractors know how to pattern-match. + +History: the manifest extractor used to be silently skipped by the sync pipeline; that was fixed in [#827](https://github.com/abhigyanpatwari/GitNexus/pull/827) (tracking issue #826). If you ever see `config.links` with zero cross-links in `contracts.json`, make sure you're on a build that includes that fix, then re-run `group sync`. + +## Troubleshooting + +1. **`contracts.json` is empty after a sync.** Either no member repo contained a recognizable gRPC pattern, or the extractors are disabled in `detect`. Confirm `detect.grpc: true` and re-run with `--verbose`. +2. **A known provider/consumer pair doesn't cross-link.** Most common cause: the package segment differs. Check the raw contract ids with `gitnexus group contracts --unmatched` — if you see two same-method contracts with different package prefixes, add a manifest `links:` entry to bridge them (no automatic rewrite rules yet). +3. **`matchType: "manifest"` is missing entirely.** The extractor needs `config.links` to be non-empty and the sync pipeline to actually call it — verify you're on a post-#827 build. Empty contract rows for manifest links usually mean `resolveSymbol` couldn't find a graph match; the synthetic uid still lets cross-impact work, it just won't carry a file path. +4. **Ambiguous proto warnings.** Look for `[grpc-extractor] Ambiguous proto resolution` in the sync logs; that means a service name exists in multiple `.proto` files under the same repo and the path-distance heuristic couldn't pick a winner. Resolve by renaming the service or declaring the intended pairing in `config.links`. +5. **Cross-impact says "stale".** Both sides need a fresh per-repo index _and_ a fresh group sync. Order matters: `gitnexus analyze` in each changed repo, then `gitnexus group sync `.

Their lifecycles differ: + * + * - `LanguageProvider` (`language-provider.ts`) is the + * **parsing-side** contract — how to emit captures, classify + * scopes, interpret imports / typeBindings. ~40 fields covering + * both legacy and new pipelines. Consumed by `ScopeExtractor`, + * once per file at extract time. + * - `ScopeResolver` (this file) is the **emit-side** contract — how + * the resolution pipeline dispatches references to graph edges. + * 8 fields total. Consumed by `runScopeResolution`, once per + * workspace at resolve time. + * + * They share three concept names (`arityCompatibility`, `mergeBindings`, + * `resolveImportTarget`) because the emit pipeline reuses a few + * finalize hooks. Per-language wiring passes the SAME function + * reference through both interfaces — no second copy of the logic. + * Rationale for not collapsing: lifecycle separation, and merging + * would create a god-interface complicating future migrations. + * + * ## Reference implementation + * + * `gitnexus/src/core/ingestion/languages/python/scope-resolver.ts` — + * `pythonScopeResolver` is the canonical example. Read that file when + * migrating a new language; this interface lists the fields that + * implementation populates. + * + * ## Contract Invariants the orchestrator depends on + * + * These are non-obvious behaviors that the orchestrator and the + * existing Python + C# resolvers depend on. Future implementers will + * break them silently if not documented. + * + * - **I1 — Phase 4 emission order is load-bearing.** `emitReceiverBoundCalls` + * runs FIRST (populates `handledSites`), then `emitFreeCallFallback`, + * then `emitReferencesViaLookup` (consumes `handledSites` as a skip + * set), then `emitImportEdges`. Reordering breaks same-name collision + * resolution: the shared lookup can mis-resolve `app_metrics.get_metrics()` + * to a same-named local function, and only the precise per-receiver + * pass running first prevents the wrong edge. + * + * - **I2 — `handledSites` semantics.** A site is added to + * `handledSites` IFF a `tryEmitEdge` call returned `true` for it. + * Sites a pass touched but couldn't resolve do NOT get marked — + * they still get a chance from the shared resolver. Exception: + * the free-call fallback marks the site unconditionally after + * attempting emission (even on dedup-collapse), because the + * per-(caller, target) collapse semantics require multiple call + * sites in the same caller body not produce multiple edges. + * + * - **I3 — `propagateImportedReturnTypes` mutation timing.** The + * pass mutates `Scope.typeBindings` (a plain `new Map(...)` from + * `draftToScope`, NOT frozen). It MUST run AFTER `finalizeScopeModel` + * (so `indexes.bindings` is populated) and BEFORE + * `resolveReferenceSites` (so resolution sees the propagated types). + * The pass also re-runs `followChainPostFinalize` on every scope's + * typeBindings because scope-extractor's pass-4 already ran and + * missed any chain whose terminal lives in a foreign file. + * + * - **I4 — `emitReceiverBoundCalls` case order.** Cases are evaluated + * in this order; the FIRST that emits an edge wins: + * 1. super branch (`provider.isSuperReceiver(receiverName)`) + * 2. Case 0 compound (`receiverName` has `.` or `(`) + * 3. Case 1 namespace-receiver + * 4. Case 2 class-name receiver + * 5. Case 3 dotted typeBinding for namespace prefix + * 6. Case 3b chain-typebinding (compound resolver) + * 7. Case 4 simple typeBinding (MRO walk + findOwnedMember) + * Reordering or merging cases changes resolution semantics. The + * numbering is part of the contract — keep the comments. + * + * - **I5 — Pre-seeding `seen` from `referenceIndex` is forbidden.** + * Earlier versions of the receiver-bound pass pre-populated `seen` + * to avoid double-emit. After Phase 4 was reordered, pre-seeding + * became actively harmful: it suppresses correct emissions for + * sites the shared resolver happened to resolve to a wrong target. + * The orchestrator MUST NOT pre-seed. + * + * - **I6 — `Scope.typeBindings` is mutable post-finalize.** `draftToScope` + * (in `scope-extractor.ts`) builds `typeBindings` as a plain + * `new Map(...)` — not frozen, intentionally. Passes below rely on + * this. Do NOT freeze `typeBindings` in any downstream refactor. + * + * - **I7 — `ScopeResolver` and `LanguageProvider` are distinct contracts.** + * Python and C# pass the SAME function reference through both + * interfaces where they share a hook name — no second copy of the + * logic. Rationale for not collapsing them: lifecycles differ + * (parsing-side runs once per file at extract time, emit-side runs + * once per workspace at resolve time), and merging would create a + * god-interface that complicates future migrations. + * + * - **I8 — Post-finalize hooks may mutate `Scope.typeBindings` and + * `indexes.bindings`.** `propagateImportedReturnTypes` and + * `populateNamespaceSiblings` both write to these structures via + * `as Map<...>` casts through `ReadonlyMap` facades. Downstream + * consumers MUST NOT freeze or snapshot these maps before all + * post-finalize hooks have run. The `ReadonlyMap<...>` type on + * `ScopeResolutionIndexes` is a read-guidance surface for + * consumers, NOT an immutability promise during the resolve phase. + * + * - **I9 — `SemanticModel` is the single authoritative symbol store.** + * Every symbol-indexed lookup (key = `nodeId | simpleName | + * qualifiedName | filePath`) resolves through + * `SemanticModel.{symbols,types,methods,fields}`. Scope-resolution + * passes MUST NOT maintain parallel owner-keyed or name-keyed + * symbol indexes — `WorkspaceResolutionIndex` is reserved for + * `Scope`-valued lookups that `SemanticModel` structurally cannot + * carry. + * + * The `runScopeResolution` orchestrator guarantees this invariant + * in two steps: + * 1. The legacy `parse` phase populates `SemanticModel` via + * `symbolTable.add(...)`. For languages whose extractor + * resolves `enclosingClassId` at parse time, class-body defs + * are correctly owner-keyed there. + * 2. The `reconcileOwnership` pass runs after + * `provider.populateOwners(parsed)` and registers any def in + * `parsed.localDefs[i]` with a corrected `ownerId` that the + * legacy pass missed (primarily Python class-body methods). + * Idempotent — duplicates are skipped by `nodeId`. + * + * Contract for consumers: `model` is `MutableSemanticModel` only + * during those two write phases. Downstream passes receive a + * narrowed `SemanticModel` (read-only) handle. This is enforced by + * `runScopeResolution`'s type-level narrowing at the phase + * boundary. + * + * The dev-mode runtime validator (`validateOwnershipParity`) + * surfaces any drift between `parsed.localDefs` ownership and the + * registries via `onWarn` when + * `NODE_ENV !== 'production' && VALIDATE_SEMANTIC_MODEL !== '0'`. + * + * This invariant is a **transitional shim**: the architectural + * end state is for every language's parse-time extractor to emit + * the correct `ownerId` directly, removing the need for + * reconciliation.
