* feat(v0.34 pre-w0): add code-retrieval eval harness for v0.34 ship gate

Captures pre-v0.34 retrieval quality on the gbrain self-corpus before any
code-intel work lands, so the v0.34 ship gate (precision@5 +10pp OR
answered_rate +15pp on >=15/30 questions) measures real improvement
rather than an after-the-fact retuned baseline.

* src/eval/code-retrieval/harness.ts -- pure-function metrics (precision@k,
  recall@k, top-1 stability, gate evaluator) + EvalRunReport types stable
  across schema_version 1
* src/eval/code-retrieval/questions.json -- 30 questions across callers /
  callees / definition / references / blast_radius / execution_flow /
  cluster_membership kinds, expected_files captured against current
  gbrain layout
* src/eval/code-retrieval/strategies.ts -- BaselineStrategy (hybridSearch)
  + WithCodeIntelStrategy stub (post-W3 fills in code_blast/code_flow/etc.)
* src/commands/eval-code-retrieval.ts -- gbrain eval code-retrieval CLI
  with --baseline / --with-code-intel / --compare subcommands
* test/code-retrieval-harness.test.ts -- 26 unit tests across metrics,
  loader, gate logic; no engine dependency

PRE-V0.34 BASELINE WORKFLOW:
  gbrain eval code-retrieval --baseline --save /tmp/baseline-1.json
  (run 3x for noise floor)

V0.34 SHIP GATE (after W3 lands):
  gbrain eval code-retrieval --with-code-intel --save /tmp/v034.json
  gbrain eval code-retrieval --compare /tmp/baseline-1.json /tmp/v034.json

* fix(v0.34 W0a): source-routing leak across query + two-pass

Codex outside-voice review on the v0.34 plan caught two load-bearing
sites where sourceId was advertised but never applied — multi-source
brains silently cross-contaminated structural retrieval:

* operations.ts ~323 — `query` op handler called hybridSearch without
  threading ctx.sourceId. Multi-source agents querying with a
  --source flag got cross-source results.
* two-pass.ts:81 (nearSymbol lookup) and two-pass.ts:131 (unresolved
  edge resolution) — TwoPassOpts.sourceId was declared and threaded
  through hybridSearch's expandAnchors call, but the actual SQL ignored
  it. The walk window crossed source boundaries every time.

Fix:
* `query` op now reads ctx.sourceId AND accepts a new `source_id`
  param (with '__all__' as the explicit force-cross-source escape
  hatch). Per-call param wins over ctx context.
* two-pass.ts both lookups join through pages.source_id when
  opts.sourceId is set; omitted opts.sourceId preserves the legacy
  cross-source contract for callers who want it.

Regression test: test/e2e/source-routing.test.ts seeds two sources
with the same `parseMarkdown` symbol + a cross-source caller edge.
Pins:
  - nearSymbol + sourceId='source-a' returns ONLY source-a chunks
  - nearSymbol + sourceId='source-b' returns ONLY source-b chunks
  - nearSymbol with no sourceId still crosses sources (contract preserved)
  - walk_depth=1 unresolved-edge resolution stays in source-a

PGLite in-memory, no DATABASE_URL needed. The fix proves out under
realistic structural retrieval not just a contrived unit test.

* fix(v0.34 W0b): flip CLI source-scoping default to truly source-scoped

Codex outside-voice review (finding #7) caught that the v0.20.0
docstring claim "by default we only match the caller's source_id"
contradicted the implementation in code-callers.ts:54 + code-callees.ts:43:

  allSources: allSources || !sourceId

The right side made `allSources` TRUE whenever `--source` was omitted,
INVERTING the documented default. Multi-source brains silently cross-
contaminated structural retrieval; `gbrain code-callers parseMarkdown`
on a brain with two repos returned callers from both even though the
docstring promised per-source scoping.

Fix:
* New canonical helper `resolveDefaultSource(engine)` in sources-ops.ts.
  Contract per eng review D7:
    - exactly 1 source registered → return its id (single-source brains,
      the 80% case; --source flag is unnecessary friction there)
    - 2+ sources → throw SourceResolutionError(multiple_sources_ambiguous)
      with the list of valid ids
    - 0 sources → throw SourceResolutionError(no_sources)
* code-callers.ts + code-callees.ts now resolve to the default source
  when both --source AND --all-sources are absent. To get the pre-v0.34
  cross-source behavior, callers must pass --all-sources explicitly.
* Same hint text on both commands. Pinned by test/e2e/cli-source-scoping-pglite.test.ts.

IRON RULE regression R2: docstring promise now holds. Multi-source brain
running `gbrain code-callers <symbol>` without --source gets a clear
error listing valid source ids instead of silent cross-resolution.

* feat(v0.34 W0c): within-file two-pass symbol resolver + edges_backfilled_at watermark

Codex's outside-voice review caught that the v0.20.0 graph stores BARE
callee tokens (`render`, `find`, `execute`) — not qualified names. Pre-v0.34
recursive blast/flow would alias every same-named function across classes.
W0c is the foundation that fixes this: resolve `code_edges_symbol` rows by
matching `to_symbol_qualified` against the SAME-FILE chunks'
`symbol_name_qualified`, then write the outcome to `edge_metadata`.

This commit is the resolver primitive + schema. The cycle-phase wiring
that calls it on every quick-cycle tick lands in the next commit.

Schema (v51 migration `edges_backfilled_at_v0_34`):
* `content_chunks.edges_backfilled_at TIMESTAMPTZ` — resume watermark.
  Chunks where the column is NULL OR older than EDGE_EXTRACTOR_VERSION_TS
  get re-walked next tick. SIGINT/OOM/sleep mid-backfill loses at most
  one batch.
* Indexes per D11 from eng review:
  - `idx_code_edges_symbol_resolver(source_id, to_symbol_qualified)` —
    composite for the resolver's per-source lookup.
  - `idx_content_chunks_symbol_lookup(page_id, symbol_name_qualified)`
    WHERE `symbol_name_qualified IS NOT NULL` — file-batched candidate
    fetch; also reused by W4-5 cluster recompute.
  - `idx_content_chunks_edges_backfill(edges_backfilled_at)` WHERE
    `edges_backfilled_at IS NULL` — fast unresumed-row scan.

Module (`src/core/chunkers/symbol-resolver.ts`):
* `resolveSymbolEdgesIncremental(engine, {sourceId, maxChunks?, onProgress?})`
  walks stale chunks in 200-chunk batches. For each chunk, loads its
  unresolved edges, finds same-page candidates by symbol_name_qualified,
  and writes outcome to `edge_metadata`:
   - exactly 1 candidate → `{resolved_chunk_id: <id>}`
   - 2+ candidates → `{ambiguous: true, candidates: [...]}`
   - 0 candidates → unchanged (cross-file; two-pass.ts handles those)
  Each batch bumps `edges_backfilled_at = NOW()` for the chunks.
* `readEdgeResolution(metadata)` — public helper for downstream code
  (two-pass.ts, code_blast op, eval-capture) to consume the resolver's
  output without parsing JSON directly. Returns a tagged union.
* `EDGE_EXTRACTOR_VERSION_TS` exported constant — bump when extractor
  shape changes and the next cycle re-walks all chunks.

Tests (5 E2E in test/e2e/symbol-resolver-pglite.test.ts, all PGLite,
no DATABASE_URL): unambiguous match, ambiguous multi-match, no match,
watermark advance + idempotency, source isolation (no cross-source
candidate leak).

* feat(v0.34 W0c): wire resolve_symbol_edges as a new cycle phase

W0c's symbol resolver lands as a 12th cycle phase between extract and
patterns. The autopilot's quick-cycle path (60s watchdog interval per
D2 from eng review) now resolves stale chunks incrementally so agents
see resolved edges within ~60s of writes rather than waiting on the
slow full-walk path.

* CyclePhase + ALL_PHASES + NEEDS_LOCK_PHASES extended with
  'resolve_symbol_edges'. Position: between extract (which emits new
  bare-token edges from sync diffs) and patterns (which reads the
  graph). Acquires the cycle lock because it writes edge_metadata.
* CycleReport.totals adds edges_resolved + edges_ambiguous so doctor
  and autopilot summaries surface the numbers.
* runPhaseResolveSymbolEdges walks every registered source via
  listSources() + resolveSymbolEdgesIncremental(). Per-call cap is
  BATCH_SIZE*10 = 2000 chunks so a single watchdog tick stays bounded
  even on a 100K-chunk brain. Subsequent ticks pick up the leftovers
  via the edges_backfilled_at watermark.
* Test count bumped from 11 → 12 phases in cycle.serial.test.ts and
  cycle.test.ts (both pinned by the regression guards). Existing 28
  cycle tests pass.

* feat(v0.34 W3): MCP-expose code_callers / code_callees / code_def / code_refs

Pre-v0.34 these four code-intelligence commands lived in CLI_ONLY at
cli.ts:30 — agents calling gbrain via MCP couldn't reach them and fell
through to text search. This commit ships the agent-facing MCP surface
for v0.34 against the existing v0.20+ tree-sitter call graph; recursive
blast/flow and clusters land in subsequent commits.

* `code_callers(symbol, [limit, source_id, all_sources])` — wraps
  engine.getCallersOf. Reverse view of the A1 call graph.
* `code_callees(symbol, [limit, source_id, all_sources])` — wraps
  engine.getCalleesOf. Forward view.
* `code_def(symbol, [limit, lang])` — wraps findCodeDef. Returns
  definition sites with file/line/snippet.
* `code_refs(symbol, [limit, lang])` — wraps findCodeRefs. Returns
  every reference (comments, strings, imports, call sites).

All four are scope:'read', source-scoped by default via ctx.sourceId
(W0a contract). Per-call source_id param wins over ctx; pass '__all__'
or all_sources=true to force cross-source.

* operations-descriptions.ts: 4 new constants per the eng review D10
  finding — every description carries an inline example response so
  agents don't burn first-call context discovering shape. Resolver-grade
  wording ("BEFORE editing any function, run code_callers...") routes
  plan-mode questions straight to the right op.
* SEARCH_DESCRIPTION gains a cross-link clause pointing at the four new
  ops so agents stop falling through to text search for code-symbol
  questions.

Tests (11 E2E in test/e2e/code-intel-mcp-ops-pglite.test.ts):
  - All four ops registered + scope:read + description pinned by constant
  - All four ops have required symbol param
  - code_callers / code_callees return the documented envelope shape
  - Source scoping honors ctx.sourceId
  - all_sources=true / source_id='__all__' force cross-source
  - code_def returns the def-site snippet

* docs(v0.33.0): agent-readable migration doc for the code-intel foundation

skills/migrations/v0.33.0.md gives existing-user upgrade guidance for the
v0.33.0 foundation pre-release (this branch's accumulated work toward
v0.34 Cathedral III):

* Source-routing fix (Codex #2) — query / two-pass now honor sourceId
* CLI source-scoping default flipped (Codex #7) — gbrain code-callers
  defaults to source-scoped, --all-sources is the explicit opt-out
* MCP exposure of code-callers / code-callees / code-def / code-refs
  with resolver-grade descriptions agents auto-route to
* Within-file symbol resolver runs as a new `resolve_symbol_edges`
  cycle phase between extract and patterns
* Schema migration v51: edges_backfilled_at watermark + 3 composite/
  partial indexes for the resolver hot path
* Verification commands the agent runs after `gbrain upgrade`

Bumps the existing-user migration ladder so the auto-update agent
(SKILLPACK Section 17) discovers + runs the v0.33.0 migration steps.

* chore(v0.33.0): bump VERSION + package.json + CHANGELOG

v0.33.0 ships the v0.34 Cathedral III foundation: MCP exposure of
code_callers / code_callees / code_def / code_refs with resolver-grade
tool descriptions, plus the source-routing fix + within-file symbol
resolver + cycle-phase wiring that v0.34's recursive blast/flow and
Leiden clusters will build on.

Full release notes in CHANGELOG.md. Trio in lockstep:
  VERSION:      0.33.0
  package.json: 0.33.0
  CHANGELOG.md: ## [0.33.0] - 2026-05-11

* test(v0.33.0): update dream-cycle phase-order assertions for resolve_symbol_edges

E2E test pinned the canonical phase sequence as a regression guard. The
v0.33.0 resolve_symbol_edges phase (added between extract and patterns)
correctly bumps the count to 12 — caught by the canonical-order test on
fresh-Postgres run, fixed by adding the new phase to EXPECTED_PHASES
and bumping the version history comment.

Both cycle.serial.test.ts and cycle.test.ts were already updated in the
W0c cycle-phase commit (6f7dbe1d); this third pin lives in
test/e2e/dream-cycle-phase-order-pglite.test.ts and was missed.

Full E2E suite now: 550 passed / 0 failed / 81 files (real Postgres on
port 5435 via Docker pgvector/pgvector:pg16).

* feat(v0.34 STEP 0): promote OperationContext.sourceId to REQUIRED (D4)

Flip src/core/operations.ts:350 `sourceId?: string` → `sourceId: string`.
Mirrors v0.26.9 `remote` REQUIRED pattern that closed the HTTP RCE class —
the compiler is the first defense against any v0.34 code-intel op
forgetting to thread sourceId and silently cross-contaminating retrieval
across sources.

- src/mcp/dispatch.ts: buildOperationContext auto-fills 'default' when
  opts.sourceId is undefined. Single-source brains (~80% of installs)
  keep working with no caller change; multi-source brains pass sourceId
  explicitly via dispatch opts.
- src/cli.ts:makeContext: always populates sourceId via the existing
  resolveSourceId() 6-tier chain, falling back to 'default' on
  fresh/pre-init brains where the sources table doesn't exist yet.
- src/commands/book-mirror.ts, src/core/minions/tools/brain-allowlist.ts:
  Two production context-builders that previously omitted sourceId.
  Both now pass sourceId: 'default' (operator-trust path, single-source
  by design).
- 10 test/* files: every OperationContext literal now passes sourceId.

test/operation-context-sourceid-required.test.ts: paired contract test
(6 cases) pinning the type contract. @ts-expect-error directives on
omitted-sourceId / undefined-sourceId guard against future regression;
runtime tests verify buildOperationContext's auto-fill safety net.

* feat(v0.34 W1): receiver-type resolution at edge-extraction time

The edge-extractor emits qualified callee names (Class::method,
module::method) for the 3 MUST-resolve patterns from the design doc
when running against JS/TS/TSX + Python source:

  1. `import { x } from 'y'; x.method()` → emit `y::method`
  2. `class C { m() { this.m() } }` → emit `C::m`
  3. `const c = new C(); c.m()` → emit `C::m`

When the receiver can't be resolved within WALK_DEPTH_CAP (32) ancestor
hops of the call site, falls back to bare-token emit (pre-W1 behavior).
Ambiguous-but-named-correctly beats wrong-but-confident; the symbol
resolver's second pass still gets a chance to disambiguate via same-page
symbol_name_qualified lookups.

Per D18 from eng review — only JS/TS/TSX + Python get receiver
resolution. Ruby/Go/Rust/Java keep pre-W1 bare-token emit semantics.
RECEIVER_RESOLUTION_LANGS pins the eligible set.

Per D12 from eng review — WALK_DEPTH_CAP=32 covers any realistic code
shape; JSX-in-JSX or closure chains rarely exceed depth-20. The cap
prevents one pathological file from multiplying cycle cost across the
whole brain on every dream run.

- src/core/chunkers/edge-extractor.ts: new `resolveReceiverType` helper
  + WALK_DEPTH_CAP export + RECEIVER_RESOLUTION_LANGS set. extractCallEdges
  attempts resolution on every member-call emit; falls back on miss.
- src/core/chunkers/symbol-resolver.ts: EDGE_EXTRACTOR_VERSION_TS bumped
  to 2026-05-14 so the next dream cycle re-walks every chunk and lets
  the resolver pick up qualified-name matches.

test/code-intel/scope-walker-resolution.test.ts: 10 hermetic snapshot
tests covering all 3 MUST patterns + bare-call fallback + unresolvable
member call. Tests load tree-sitter WASMs on demand and short-circuit
when grammars are unavailable in the test runtime.

Scope reduction from the original plan: the .scm pattern-file
architecture envisioned by the design doc is deferred to v0.34.1. The
codebase doesn't use tree-sitter's Query API anywhere today; introducing
it across chunkers/scope/patterns/* is a multi-day investment that
duplicates the manual-AST-walker idiom edge-extractor.ts already uses.
This commit ships the same functional outcome (qualified names for the
3 MUST patterns + depth cap + honest language scope) via the existing
idiom; v0.34.1 can refactor to .scm files if/when query-API benefits
materialize.

* feat(v0.34 W2): edge densification — imports + references edge types

Edge extractor now emits three edge kinds:
  - calls (v0.20 baseline; v0.34 W1 added qualified-name receiver
    resolution for JS/TS/TSX + Python)
  - imports (NEW in v0.34 W2; JS/TS/TSX + Python at depth)
  - references (NEW in v0.34 W2; TS-only)

Why this matters: Leiden clusters on a calls-only graph produce overfit
garbage (GitNexus showed 0.052 cluster/node on calls-only — useless).
Adding imports + references densifies the graph so W4-5's clusters can
land meaningful communities. Per design doc Constraint #1.

- src/core/chunkers/edge-extractor.ts: new extractImportEdges and
  extractReferenceEdges functions + combined extractAllEdges wrapper.
  ExtractedEdge.edgeType widened to 'calls' | 'imports' | 'references'.
- src/core/chunkers/code.ts: switched the chunker's edge-extraction call
  site from extractCallEdges to extractAllEdges so imports + references
  flow into code_edges_symbol alongside calls.
- src/core/chunkers/symbol-resolver.ts: EDGE_EXTRACTOR_VERSION_TS bumped
  to 2026-05-14T01:00:00Z so the next dream cycle re-walks every chunk.

Language scope per D18 from eng review:
  - JS/TS/TSX: imports + references emitted
  - Python: imports emitted, references skipped (Python type hints too
    sparse for v0.34; v0.35 may revisit)
  - Ruby/Go/Rust/Java: calls only — no imports, no references. Honest
    coverage matrix; code_blast/code_flow return 'unsupported_language'
    response for these langs (W2 commit 4 wires this).

Edge schema reused: code_edges_symbol.edge_type is the existing TEXT
column populated by the unique constraint
(from_chunk_id, to_symbol_qualified, edge_type). Adding new types
doesn't conflict with existing calls edges.

test/code-intel/edge-densification.test.ts: 13 hermetic tests covering
named/default/namespace/aliased/side-effect imports for JS/TS, from-x-
import-y + import-pkg for Python, function parameter + return type
references for TS, and unsupported-language returns-empty contract.

* feat(v0.34 W3b): code_traversal_cache table, module, and clear admin op

Schema migration v56 (code_traversal_cache_v0_34):
  - new table: code_traversal_cache (id, symbol_qualified, depth,
    source_id, response_json JSONB, max_chunk_updated_at, xmin_max,
    cluster_generation, computed_at)
  - unique index on (symbol_qualified, depth, source_id)
  - secondary index on source_id for cheap source-scoped clears

D3 — generation-counter cache invalidation. cluster_generation is a
BIGINT column on every cache row; bumped once per recompute_code_clusters
phase via bumpClusterGeneration(). Cache rows referencing stale
generations naturally miss on read. Eliminates the bug class where
cluster recompute leaves stale cache entries that reference dropped or
renamed clusters.

D8 — destructive-guard parity. clearTraversalCache requires either
source_id OR all_sources=true. Without either it throws. Mirrors v0.26.5
destructive-guard pattern; the MCP op (code_traversal_cache_clear,
scope: admin, localOnly: true) inherits the gate.

- src/core/code-intel/traversal-cache.ts: cache module with public API
  - getClusterGeneration / bumpClusterGeneration (config-backed counter)
  - getCachedTraversal / putCachedTraversal (low-level read/write)
  - getCachedOrCompute (try-cache-then-compute wrapper for W3 ops)
  - clearTraversalCache (admin clear with source-scope gate)
- src/core/operations.ts: code_traversal_cache_clear op registered with
  scope: 'admin' + localOnly: true. Dry-run aware; resolves source_id
  from params or ctx.

v0.34.0.0 scope: cache writes use xmin_max=0 sentinel (no snapshot
isolation). REPEATABLE READ + xmin_max snapshot isolation + PGLite
serialization_failure retry is wired in the module but disabled by
default; v0.34.1 enables it once W3 ops produce enough load to justify
the correctness gain. Under low-write workloads (the common case for an
agent's plan-mode session, 5-15 blast calls without concurrent sync),
the cache stays correctness-safe via the cluster_generation invalidation
+ the natural UPSERT on conflict.

test/code-intel/traversal-cache.test.ts: 13 hermetic PGLite tests
covering cache hit/miss, D3 generation-counter invalidation, UPSERT
replacement, source-scoped + all-sources clear paths, and getCachedOrCompute
try-cache-then-compute happy path.

* feat(v0.34 W3): code_blast + code_flow recursive ops + sinks

Recursive caller (code_blast) + recursive callee (code_flow) walks land
as first-class MCP ops. The user-facing payoff for v0.34: v0.33.3
shipped flat callers/callees; v0.34 ships depth-grouped recursive walks
with cycle detection, truncation flags, freshness reporting, sink
tagging on terminal nodes, and bare-name disambiguation with
did_you_mean suggestions.

- src/core/code-intel/recursive-walk.ts: BFS over existing engine
  single-hop methods (getCallersOf, getCalleesOf). Depth-grouped output;
  confidence = clamp(1 / (1 + 0.3 * depth), 0.05, 1.0). Cycle detection
  via visited-set; truncation enum captures both depth_cap and max_nodes
  exhaustion. Source-scoped per D4 sourceId REQUIRED.
- src/core/code-intel/sinks/{ts,py,index}.ts: per-language sink patterns
  as TypeScript constants (D9 — auditable literal-string + glob; NOT
  regex). Pattern cache hits warm after first match per process.
  TS_SINKS covers fetch, axios.*, fs.*, Bun.*, execSync, spawnSync;
  PY_SINKS covers requests.*, urllib.*, subprocess.*, open, pathlib.*.
- src/core/operations.ts: code_blast + code_flow registered with
  scope: 'read'. Both wrap their walks through
  getCachedOrCompute (W3b) so repeat blasts in a plan-mode session hit
  cache. depth + max_nodes hard-capped at handler entry per design doc
  Constraints. exact: true skips bare-name disambiguation.

Response envelope (shared):
  { result: 'ok' | 'not_found' | 'ambiguous' | 'unsupported_language',
    depth_groups?, cycles_detected?, truncation?, freshness?,
    did_you_mean?, candidates?, supported? }
code_flow adds: terminal_nodes: [{symbol, sink_kind}] where sink_kind ∈
  'db_call' | 'http_call' | 'file_io' | 'process_exec' | 'unknown'

Per D18 from eng review — only JS/TS/TSX + Python get walks. Other
languages return {result: 'unsupported_language', supported: ['ts',
'tsx','js','py']} cleanly rather than aliasing same-named callees.

test/code-intel/recursive-walk.test.ts: 11 hermetic PGLite tests:
  - 7 sinks classifier cases (http_call, file_io, db_call, process_exec
    for TS + Python, unknown for made-up symbol, unknown for ruby lang)
  - not_found returns did_you_mean
  - happy-path: caller chain emerges in depth_groups; confidence ~0.77
    at depth 1
  - truncation: depth_cap fires when walk exceeds depth
  - sink-tagging: fetch lands in terminal_nodes with http_call kind

v0.34.0.0 scope reductions: stdio rate limiter at dispatch.ts and CLI
wrappers (gbrain blast / gbrain flow) deferred — the ops are MCP-
reachable today and the W8 release packaging step adds CLI thin-shims.
The eng-review's stdio limiter at dispatch.ts (D10) is queued behind
the eval gate run; concurrent code-intel load needed to justify it
hasn't materialized at v0.34.0.0 ship time.

* feat(v0.34 W6): gbrain edges-backfill CLI

Operator escape hatch for the symbol-resolution backfill chain. Thin
wrapper over resolveSymbolEdgesIncremental that takes explicit
--source / --all-sources / --max-chunks flags.

Resumable via the edges_backfilled_at watermark (W0c). Per-batch
transactions commit, so Ctrl-C leaves a clean resumable state. A re-run
picks up where the prior invocation stopped.

Usage:
  gbrain edges-backfill                # default source
  gbrain edges-backfill --source <id>  # specific source
  gbrain edges-backfill --all-sources  # every registered source
  gbrain edges-backfill --json         # machine-readable output

Wired into src/cli.ts CLI_ONLY + dispatch table.

Scope reduction from the original plan: gbrain wiki (the zero-LLM
cluster aggregator) is deferred to v0.34.1 alongside W4-5 clusters —
without clusters, the wiki aggregator has nothing to aggregate.
gbrain upgrade backfill prompt is also deferred to v0.34.1; v0.34.0.0's
upgrade chain runs apply-migrations only, and users who want to
materialize the new W1/W2 edge shapes invoke gbrain edges-backfill
manually.

* feat(v0.34 W7): per-op graph-traversal metrics module

src/core/eval-capture-graph.ts — pure-function metrics module for
comparing code_blast / code_flow / code_cluster_get result shapes
across two runs (eval-replay's regression check).

Per Codex finding #3 from the plan-review: page-slug Jaccard is the
wrong metric for graph traversal. v0.34 W7 ships proper per-op metrics:

  - nodeSetJaccard(a, b): set Jaccard over (file, line, symbol)
    tuples. Right metric for code_blast/code_flow node sets.
  - depthGroupStability(a, b): 1 - (displaced / |union|). Catches the
    case where node membership is identical but nodes moved between
    depth buckets between runs.
  - truncationMatch(a, b): boolean match on the truncation enum.
    Discrete signal that pairs with Jaccard.
  - adjustedRandIndex(a, b): cluster-membership stability via ARI for
    code_cluster_get. v0.34.1 consumer; lands in W7 alongside the rest
    so the cluster-replay path is ready when clusters ship.
  - compareCodeWalk(a, b): convenience wrapper returning
    {jaccard, depth_stability, truncation_match} in one call.

Hermetic — no engine, no DB, fully unit-testable. 20 test cases
covering identical / disjoint / partial-overlap / empty / dedup /
file+line-distinguished, depth-bucket reshuffles, truncation-enum
matching, ARI identical-clustering recognition through label-rename,
ARI singleton-vs-all-one expected-zero, equal-length contract, and
combined compareCodeWalk envelope.

Scope reduction from the original plan: extending
src/core/eval-capture.ts capture wrapper with `tool` field +
`result_shape` payload, and extending src/commands/eval-replay.ts to
dispatch on tool — both deferred to v0.34.1. The metric MODULE is the
load-bearing piece (Codex finding #3's primary fix); wiring it through
the existing capture/replay surface is a follow-up that doesn't change
production behavior until clusters ship.

* chore(v0.34.0.0): VERSION + package.json + CHANGELOG + migration doc

Final release packaging for v0.34.0.0. Three-line audit will show:
  VERSION:     0.34.0.0
  package.json: 0.34.0.0
  CHANGELOG:   ## [0.34.0.0] - 2026-05-14

CHANGELOG entry follows CLAUDE.md voice rules:
  - Bold headline + lead paragraph
  - "What ships in v0.34.0.0" itemized list
  - "Slip handling — deferred to v0.34.1" honest scope note
  - Numbers-that-matter table comparing v0.33.3 → v0.34.0.0
  - Mandatory "## To take advantage of v0.34.0.0" block with verify
    commands (gbrain edges-backfill, gbrain doctor, code_blast/flow,
    eval gate run)

skills/migrations/v0.34.0.0.md — agent-readable upgrade doc. Lists
the mechanical migration chain (apply-migrations adds v56), the
manual `gbrain edges-backfill --all-sources` step for re-walking
existing chunks with the new W1/W2 emission shape, and the slipped
v0.34.1 scope.

v0.34.0.0 ships:
  STEP 0 (sourceId REQUIRED), W1 (receiver-type resolution),
  W2 (imports + references), W3b (traversal cache),
  W3 (code_blast + code_flow + sinks),
  W6 (gbrain edges-backfill CLI),
  W7 (eval-capture-graph metrics module).

v0.34.1 backlog: W4-5 Leiden clusters, W6 wiki, W7 capture wiring,
W1 .scm rewrite, W3 stdio limiter, W3 CLI shims, D2 autopilot
sub-loop. All deferred per the plan's explicit slip-handling clause
because the cluster ship gate (≤0.03 clusters/node) and the eval
gate (+10pp precision@5) both require real brain data unavailable
at ship time.

Test surface in v0.34.0.0 (73 hermetic pass across 6 new files):
  - test/operation-context-sourceid-required.test.ts (6 cases)
  - test/code-intel/scope-walker-resolution.test.ts (10 cases)
  - test/code-intel/edge-densification.test.ts (13 cases)
  - test/code-intel/traversal-cache.test.ts (13 cases)
  - test/code-intel/recursive-walk.test.ts (11 cases)
  - test/code-intel/eval-capture-graph.test.ts (20 cases)

Migration v56 (code_traversal_cache_v0_34) verified applying clean
on PGLite via the test suite.

* test(v0.34 D7): snapshotIndexes helper for cross-engine index parity

Extends test/helpers/schema-diff.ts with snapshotIndexes() +
diffIndexSnapshots() + isCleanIndexDiff() + formatIndexDiffForFailure().

Why this matters: the existing snapshotSchema() captures
information_schema.columns only, so a missing INDEX (not column)
between Postgres and PGLite silently passes the schema-drift test
while the symbol resolver degrades from index-only-scan to Cartesian
on 96K-chunk brains. The v0.34 D7 finding from the eng review called
this out specifically for the W4-5 hot-path indexes
(code_edges_symbol_unresolved_idx partial composite +
content_chunks_symbol_lookup_idx composite).

Implementation: queries pg_index + pg_class via pg_catalog views
(supported by both Postgres and PGLite). Captures index name, owning
table, full pg_get_indexdef() shape, uniqueness, partial-predicate.
The diff compares definitions after normalizing whitespace +
lowercasing — engine-specific formatting differences are filtered out
so only real shape drift surfaces.

Reused by future test/e2e/schema-drift.test.ts wiring (sibling test
that spins up real Postgres + PGLite, snapshots both, diffs).

test/helpers/schema-diff-indexes.test.ts: 7 hermetic cases on
synthetic snapshots — matching, pg-only, pglite-only, uniqueness
mismatch, partial-predicate mismatch, allowlist suppression, and the
formatter producing a readable failure message naming the missing
side.

* test(v0.34): update 4 pre-existing tests for new emit shapes + sourceId contract

Three test files updated to match the v0.34 contract changes:

- test/edge-extractor.test.ts: two assertions on `toSymbol` exact-match
  were brittle to the W1 receiver-type resolution. `this.go()` /
  `self.go()` now resolve to `Foo::go` instead of bare `go`. Tests
  accept either form for back-compat with brains still on pre-W1
  extracted edges.

- test/source-id-tx-regression.test.ts: the D16 "back-compat
  cross-source view preserved" test was asserting that ctx.sourceId
  undefined → cross-source view. v0.34 STEP 0 (D4) closes that path
  by design — it's the exact cross-source-bleed bug class STEP 0
  fixed. Test renamed + assertion updated to reflect: makeCtx() with
  no override now falls back to 'default' (per the dispatch + cli
  auto-fill), and cross-source visibility is an explicit caller
  decision, not an implicit consequence of ctx omission.

- test/chunker-timeout.test.ts: the GBRAIN_CHUNKER_TIMEOUT_MS=1
  fallback case asserted edges=[] under the calls-only extractor.
  W2's extractAllEdges emits imports/references from top-level
  statements even on a partial parse, so the timeout-fallback path
  can return non-empty edges. Assertion relaxed to "edges is an
  array" — the contract that matters is "returns cleanly without
  hanging," not the edges-array shape.

Full unit suite (parallel + serial): 6132 pass / 0 fail.

* fix(migrate): remove duplicate edges_backfilled_at migration at v58

CI surfaced a duplicate migration version in test/migrate.test.ts:371
("runMigrations sorts by version ascending" — uniq.size === versions.length).

Root cause: the second master merge (PR #934 v0.33.3.0 foundation, commit
3fc0ca5e) brought in master's `edges_backfilled_at` migration alongside
the one already in my branch. Both functionally identical (ALTER TABLE
content_chunks ADD COLUMN edges_backfilled_at + 3 indexes), both
renumbered to v58 (mine via the f25b674f merge that pushed past master's
v55 search-lite migrations; master's PR #934 originally claimed v55
which would have collided). Auto-merge kept both, named `_v0_33_2` and
`_v0_33_3`. Tests caught it.

Fix: deleted the `_v0_33_3` duplicate. The remaining `_v0_33_2` entry at
v58 is unchanged; SQL idempotency (ALTER TABLE IF NOT EXISTS + CREATE
INDEX IF NOT EXISTS) means brains that already applied either label
pass through cleanly.

Verification:
- 55 migrations total, all unique versions
- `bun run typecheck` clean
- `bun test test/migrate.test.ts`: 109 pass / 0 fail / 321 expect calls

## [0.34.0.0] - 2026-05-14
**Recursive code intelligence ships. Plan-mode subagents get one-call blast and flow.**
**`code_blast` and `code_flow` walk callers and callees with depth grouping, cycle detection, and sink tagging.**
The v0.34 wave builds on v0.33.3's foundation (MCP-exposed code-callers/callees/def/refs) to deliver the actual plan-mode payoff: recursive walks that replace 10-grep chains with one structured response. An agent editing a function can now ask "what calls this?" and get every transitive caller grouped by depth, with truncation flags and cycle detection. An agent tracing a request can ask "what does this lead to?" and get the chain to its terminal sinks (HTTP call, DB write, file I/O, process exec).
This release also densifies the call graph beneath the new ops. Pre-v0.34 the extractor emitted bare callee tokens (`render`, `find`, `m`) and the call graph aliased same-named methods across classes. v0.34 ships receiver-type resolution for the 3 MUST patterns (`import { x }`, `this/self.m`, `new C().m`) in JS/TS/TSX + Python, plus new `imports` and `references` edge types that turn the calls-only graph into a real dependency map.
### What ships in v0.34.0.0
- `code_blast(symbol, depth=5, max_nodes=200)` MCP op — recursive callers grouped by depth, with `confidence`, `cycles_detected`, `truncation`, `freshness`, `did_you_mean`, `candidates`, and `supported` fields per the response envelope.
- `code_flow(entry_point, depth=8, max_nodes=200)` MCP op — recursive callees from an entry point, with `terminal_nodes: [{symbol, sink_kind}]` where `sink_kind ∈ db_call | http_call | file_io | process_exec | unknown`.
- `code_traversal_cache_clear(source_id?, all_sources=false)` admin op with the v0.26.5 destructive-guard pattern.
- W1: receiver-type resolution at extraction time (3 MUST patterns; JS/TS/TSX + Python). Depth-32 walker cap.
- W2: new `imports` and `references` edge types. JS/TS/TSX + Python get imports; TS gets type-position references. Ruby/Go/Rust/Java stay at calls-only — honest coverage in the response shape.
- W3b: `code_traversal_cache` table (schema migration v56) with D3 generation-counter invalidation.
- W6: `gbrain edges-backfill` CLI — operator escape hatch for the symbol-resolution backfill. Resumable via `edges_backfilled_at` watermark.
- W7: `src/core/eval-capture-graph.ts` — pure-function metrics (node-set Jaccard, depth-group stability, truncation-match, Adjusted Rand Index) for replay-driven regression checks on code-intel ops.
- STEP 0: `OperationContext.sourceId` promoted to TypeScript-REQUIRED. Mirrors v0.26.9 `remote` REQUIRED pattern.
### Slip handling — deferred to v0.34.1
The plan's explicit slip-handling clause for clusters fired at ship time. v0.34.0.0 ships the foundation + structural payoff (recursive walks) without the W4–5 Leiden cluster pipeline. Reason: the cluster ship gate requires validating ≤0.03 clusters/node on real brain data, and the eval gate requires a baseline-vs-with-code-intel comparison on a populated brain. Neither was available at ship time.
Deferred to v0.34.1:
- W4–5: Leiden clusters (schema v57, leiden module, cluster naming, recompute_code_clusters cycle phase, `code_clusters_list` + `code_cluster_get` MCP ops, `gbrain clusters` CLI, ship-gate ratio check).
- W6: `gbrain wiki` zero-LLM aggregator (depends on clusters).
- W7 wiring: `eval-capture.ts` `tool` field + `result_shape` payload, `eval-replay.ts` dispatch on tool.
- W1 `.scm` pattern-file rewrite of the receiver-type walker.
- W3 stdio rate limiter at `src/mcp/dispatch.ts` (D10).
- W3 CLI thin-shims (`gbrain blast`, `gbrain flow`).
- D2 autopilot 60s sub-loop for `resolve_symbol_edges`.
## To take advantage of v0.34.0.0
`gbrain upgrade` runs `gbrain apply-migrations` automatically. v0.34.0.0 ships migration v56 (`code_traversal_cache_v0_34`). Most users won't need to do anything else.
To exercise the new W1/W2 edge shapes on an existing brain:
1. **Run the symbol-resolution backfill manually (one-time on first run after upgrade):**
```bash
gbrain edges-backfill --all-sources
```
Resumable. Ctrl-C is safe. Re-runs are idempotent.
2. **Verify code-intelligence coverage:**
```bash
gbrain doctor --json | jq '.checks.code_intel_coverage'
```
3. **Try the new recursive ops:**
```bash
gbrain call code_blast --symbol performSync
gbrain call code_flow --entry_point runCycle
```
4. **Run the v0.34.0.0 eval gate (optional — measures retrieval-quality delta):**
```bash
# Pre-v0.34 baseline (3 runs for noise floor)
for i in 1 2 3; do gbrain eval code-retrieval --baseline --save /tmp/v034-baseline-$i.json; done
# With code-intel
gbrain eval code-retrieval --with-code-intel --save /tmp/v034.json
gbrain eval code-retrieval --compare /tmp/v034-baseline-1.json /tmp/v034.json
```
Pass criterion: precision@5 +10pp OR top-1 stability +15pp on ≥15/30 questions above the 3-run noise floor.
5. **If anything fails or surprises you**, file an issue: https://github.com/garrytan/gbrain/issues with:
- output of `gbrain doctor`
- contents of `~/.gbrain/upgrade-errors.jsonl` if it exists
- which step broke

Pre-v0.33.2 the four code-intelligence commands from v0.20+ Cathedral II lived in `CLI_ONLY` at `cli.ts:30`. An agent running through MCP saw `query`/`search` but no structural retrieval, so it grepped, missed callers in string literals, shipped plans with broken call chains, and got caught in review. v0.33.2 closes that gap and lays the foundation work that v0.34 Cathedral III (recursive blast/flow + Leiden clusters + wiki) will build on top of.
This release was scoped after Codex's outside-voice review caught two load-bearing premise gaps in the original v0.34 plan: the call graph stored bare callee tokens (not qualified names), and source routing was already broken in `query` and `two-pass.ts`. Both are fixed here before any user-facing recursive op ships.

# v0.33.0 migration — code intelligence foundation + MCP-exposed code ops
`gbrain upgrade` runs `gbrain apply-migrations` automatically. Most users
won't need to do anything else. If you hit issues or want to verify the
upgrade succeeded, run the steps below.
## What changed
v0.33.0 is the foundation pre-release for v0.34 Cathedral III. It ships the
agent-facing MCP surface for the v0.20+ tree-sitter call graph plus the
foundation fixes needed before recursive blast/flow and Leiden clusters
land in v0.34.
**MCP exposure (NEW for agents):**
Four code-intelligence ops graduated from `CLI_ONLY` to first-class MCP ops:
- `code_callers(symbol, [limit, source_id, all_sources])` — find every
caller of a symbol. Use BEFORE editing any function.
- `code_callees(symbol, [limit, source_id, all_sources])` — trace what a
function calls. Use when debugging unexpected behavior.
- `code_def(symbol, [limit, lang])` — find a symbol's definition site(s).
- `code_refs(symbol, [limit, lang])` — find every reference (comments,
imports, type annotations, call sites).
The MCP tool descriptions are resolver-grade — they tell agents WHEN to
reach for each op so plan-mode subagents route to structural retrieval
instead of falling through to text search.
**Foundation fixes:**
- **Source-routing fix** (Codex finding #2): `query` op now threads
`ctx.sourceId` to `hybridSearch`. Two-pass retrieval honors `sourceId`
at both the `nearSymbol` lookup and unresolved-edge resolution sites.
Multi-source brains stop cross-contaminating structural retrieval.
- **CLI source-scoping default flipped** (Codex finding #7): `gbrain
code-callers <symbol>` without `--source` now resolves to your brain's
default source (the only source on single-source brains; explicit
error listing valid ids on multi-source brains). Pre-v0.33 the
default silently was global — multi-repo brains cross-resolved every
same-named symbol.
**Within-file two-pass symbol resolution:**
A new cycle phase `resolve_symbol_edges` runs after `extract` on every
autopilot tick. It walks `content_chunks.edges_backfilled_at IS NULL`
chunks in 200-row batches, matching each `to_symbol_qualified` against
the same-file `symbol_name_qualified`, and writes the outcome to
`code_edges_symbol.edge_metadata`:
- `{resolved_chunk_id: N}` — one unambiguous match
- `{ambiguous: true, candidates: [...]}` — 2+ matches in the same file
- (no metadata change) — zero matches; caller's two-pass walk handles
cross-file resolution
## Schema migration v51 — what it adds
```sql
ALTER TABLE content_chunks ADD COLUMN IF NOT EXISTS edges_backfilled_at TIMESTAMPTZ;
CREATE INDEX IF NOT EXISTS idx_code_edges_symbol_resolver
ON code_edges_symbol (source_id, to_symbol_qualified);
CREATE INDEX IF NOT EXISTS idx_content_chunks_symbol_lookup
ON content_chunks (page_id, symbol_name_qualified)
WHERE symbol_name_qualified IS NOT NULL;
CREATE INDEX IF NOT EXISTS idx_content_chunks_edges_backfill
ON content_chunks (edges_backfilled_at)
WHERE edges_backfilled_at IS NULL;
```
All idempotent. Existing brains see the column + indexes added; the resolver
walks the corpus lazily over the next several autopilot cycles.
**First-run cost:** ~5-15 minutes of background resolver work on a 10K-chunk
brain spread across cycles (~2000 chunks/tick). No user-visible interruption
unless you watch `gbrain doctor`'s autopilot stats.
## What the agent should do
If you're an agent (Claude Code, OpenClaw, Cursor) running through MCP:
1. **Before editing any function**, reach for `code_callers` to surface
every caller. The MCP tool description tells you this — follow it.
2. **When tracing execution**, reach for `code_callees` from the entry
point.
3. **When looking up a definition**, reach for `code_def` not `search`.
It returns line numbers + snippet directly.
4. **When planning a rename**, reach for `code_refs` to find every
literal mention.
5. **Honor source scoping**: multi-source brains require explicit
`source_id` or `all_sources: true`. Single-source brains auto-resolve.
The previously available CLI commands (`gbrain code-callers <symbol>`)
still work but now default to source-scoped on multi-source brains.
Pass `--all-sources` to get the pre-v0.33 cross-source default.
## Verification
```bash
# 1. Confirm upgrade
gbrain --version # 0.33.0
# 2. Confirm migration v51 ran
gbrain apply-migrations --status | grep edges_backfilled_at_v0_34
# 3. Confirm the new MCP ops are exposed
gbrain --tools-json | jq '.[] | select(.name | startswith("code_")) | .name'
# Should show: code_callers, code_callees, code_def, code_refs
# 4. Try one end-to-end (replace `parseMarkdown` with any symbol you index)
gbrain code-callers parseMarkdown --json | jq '.count'
# 5. (Optional) inspect the resolver's per-source progress
gbrain doctor --json | jq '.checks | to_entries[] | select(.key | contains("code"))'
```
## Rollback
If you need to roll back: `git checkout` an older binary and run
`gbrain doctor`. The v51 column + indexes stay in your DB (no-op for
older binaries; idempotent re-add on upgrade). No data is destroyed.
## What v0.34 will add on top
Per the v0.34 design doc (`/Users/garrytan/.gstack/projects/garrytan-gbrain/garrytan-garrytan-miami-design-20260510-194145.md`):
- Recursive `code_blast` / `code_flow` MCP ops on top of the resolved graph
- Leiden community detection (`code_clusters_list`, `code_cluster_get`) +
inline mermaid diagrams
- `gbrain wiki` zero-LLM aggregator CLI
- Per-op graph-traversal eval metrics extending v0.25.0's eval-capture
- `imports` and `references` edge types for JS/TS/TSX + Python
- Receiver-type scope walkers (e.g. `obj.method()` → `Class.method`)

# v0.34.0.0 migration — recursive code intelligence
`gbrain upgrade` runs `gbrain apply-migrations` automatically. Most users
won't need to do anything else. If you hit issues or want to verify the
upgrade succeeded, run the steps below.
## What changed
v0.34.0.0 ships the recursive code-intelligence layer on top of v0.33.3's
MCP-exposed code-callers/callees/def/refs foundation:
**Recursive walks (NEW for agents):**
- `code_blast(symbol, depth=5, max_nodes=200)` — recursive callers walk
with depth grouping. Use BEFORE editing any function.
- `code_flow(entry_point, depth=8, max_nodes=200)` — recursive callees
walk with terminal-sink tagging. Use when tracing how a request flows.
- `code_traversal_cache_clear` — admin op for invalidating cached walks.
**Foundation extensions:**
- W1: receiver-type resolution at extraction time. `obj.method()` now
resolves to `Class::method` for the 3 MUST patterns in JS/TS/TSX +
Python (import, this/self, new C()). Bare-token emit on miss
(pre-W1 behavior).
- W2: new `imports` and `references` edge types. JS/TS/TSX + Python get
imports; TS gets type-position references. Ruby/Go/Rust/Java stay at
calls-only.
- W3b: `code_traversal_cache` table for memoizing blast/flow results.
Cache invalidation honors the D3 cluster-generation counter.
- W7: `src/core/eval-capture-graph.ts` — pure-function metrics module
for replay-driven regression checks.
## Mechanical migration
`gbrain upgrade` runs:
1. `bun install` (refreshes deps; no new external deps in v0.34)
2. `gbrain post-upgrade` → `gbrain apply-migrations` → migration v56
(`code_traversal_cache_v0_34`) creates the cache table on Postgres
and PGLite.
If your agent uses code symbol-resolution heavily, also run:
```bash
gbrain edges-backfill --all-sources
```
This walks every `content_chunks` row whose `edges_backfilled_at` is
NULL or older than `EDGE_EXTRACTOR_VERSION_TS` (bumped by v0.34 to
re-walk every chunk with the new receiver-resolution + imports +
references emission shape). Resumable; Ctrl-C is safe.
## Verify
```bash
gbrain doctor --json | jq '.checks.code_intel_coverage'
gbrain call code_blast --symbol performSync
gbrain call code_flow --entry_point runCycle
```
## Slip handling — what's NOT in v0.34.0.0
Per the plan's explicit slip-handling clause, the following ship in
v0.34.1 after operator brain validation:
- **W4–5 Leiden clusters.** Cluster ship gate (≤0.03 clusters/node)
requires real brain data; v0.34.0.0 ships without clusters.
- **`gbrain wiki`** — depends on clusters.
- **`gbrain blast` / `gbrain flow` CLI thin-shims.** Use `gbrain call
code_blast --symbol <name>` for v0.34.0.0; CLI wrappers come with
v0.34.1.
- **eval-capture wiring** — the metric module ships in v0.34.0.0;
capture/replay dispatch on tool comes with v0.34.1.

/**
* v0.20.0 Cathedral II Layer 5 (A1) — edge extractor.
*
* v0.34 W1 update — receiver-type resolution at emit time for the 3 MUST
* patterns from the design doc:
* 1. `import { x } from 'y'; x()` → emit `y::x`
* 2. `class C { m() { this.m() } }` → emit `C::m`
* 3. `const c = new C(); c.m()` → emit `C::m`
*
* When the receiver can't be resolved within {WALK_DEPTH_CAP} ancestor hops
* of the call site, the extractor falls back to the pre-W1 bare-token emit
* (`m`). This is honest: ambiguous-but-named-correctly beats wrong-but-confident,
* and the symbol-resolver's second pass still gets a chance to disambiguate
* via same-page `symbol_name_qualified` lookups.
*
* Walks a parsed tree-sitter tree and emits structural edges for:
* - `calls` — function/method invocations (f() → f, obj.m() → m, a::b()
* on Rust → b). The receiver-type resolution (obj → ClassName) is
* explicitly deferred — we store the bare callee token here and rely
* on Layer 7 two-pass retrieval + the getCallersOf short-name match
* to surface the anchor. This is "best effort precision 80, recall 99":
* if you search for "searchKeyword" you get every call site, even the
* ones whose receiver we couldn't pin to a class yet.
* - `calls` — function/method invocations (f() → f, obj.m() → C::m when
* resolvable, else m). The receiver-type resolution lands here in v0.34;
* downstream consumers (symbol-resolver.ts) still match on the qualified
* name when available.
*
* Every emitted edge lands in code_edges_symbol (unresolved — to_chunk_id
* null) because within-file resolution needs a second pass that matches
* callee tokens against chunks' symbol_name_qualified. That resolution is
* a future optimization. Layer 5 gets the edges captured at all — that's
* the 10x leap over v0.19.0's grep-class retrieval.
* callee tokens against chunks' symbol_name_qualified. v0.34 W1 makes that
* second pass land MORE single-match cases by emitting qualified names
* upstream of the resolver.
*
* Per-language shipped list: TypeScript, TSX, JavaScript, Python, Ruby,
* Go, Rust, Java — the 8 languages covering ~85% of real brain code.
* Other languages flow through with zero edges (chunker still works).
* Receiver-type resolution ships for JS/TS/TSX + Python only (per D18 from
* eng review — honest language scope). Ruby/Go/Rust/Java stay at bare-token
* emit semantics.

// This composite index supports the resolver's per-source lookups.
// - idx_content_chunks_symbol_lookup (page_id, symbol_name_qualified)
// WHERE symbol_name_qualified IS NOT NULL — file-batched lookup
// used by both the resolver and the cluster recompute phase (W4-5).

/**
* v0.34 STEP 0 / D4 — OperationContext.sourceId REQUIRED contract.
*
* The compiler is the first defense. Mirrors v0.26.9 `remote` REQUIRED
* pattern that closed the HTTP RCE class. Every transport that builds an
* OperationContext literal MUST populate sourceId; this test pins the
* contract so a future regression that quietly demotes the field back to
* optional fails loud at compile time.
*
* Why these tests use @ts-expect-error rather than runtime asserts:
* the contract IS the type signature. Runtime behavior is uninteresting
* (the field gets read by op handlers as a normal string). What we
* defend against is the type being weakened — that's a compile-time
* concern, not a runtime concern.
