Thanks for this — it's a substantial piece of work, and the core ideas are right. self/cls binding, Alpha.helper() static calls, aliased class imports and qualified-name lookup across CLI/MCP are all things this index should have. Several of them measurably work (evidence below). I'm requesting changes rather than merging, because as it stands the branch also makes the call graph less trustworthy than main in four specific ways, each of which is a local fix.
How I reviewed it. Your branch is based on v0.140.0 and main is now v0.144.0, so I rebased it locally (only tests/cli_e2e.rs and tests/integration.rs conflicted — both sides had appended tests, I kept both; I verified no line from either side was lost). Then I built the base (f09bc00) and head binaries, indexed the same trees with both, and diffed the resulting edge sets rather than relying on test names:
| probe | files | base edges | head edges |
|---|---|---|---|
third-party Python corpus (/usr/lib/python3/dist-packages) |
3,818 | 529,593 | 197,835 |
| this repo's own tree (Rust 162 / JS 84 / Python 15 / …) | 307 | 12,361 | 12,354 |
| 9-file Python fixture | 9 | 29 | 20 |
The count dropping is not itself the problem — removing false positives is the point. The problem is which edges move, and that the confidence labelling shifts underneath them:
corpus `calls` edges, by confidence
base head
ambiguous 319,107 -> 11,022 (-96.5%)
extracted 67,902 -> 30,562 (-55.0%)
inferred 48,873 -> 62,260 (+27.4%)
impact defaults to --min-confidence inferred, so edges relabelled from ambiguous to inferred go from being folded out of risk scoring to being counted by it.
Blockers
1. self.method() on an inherited method is dropped entirely
SelfRecv(Class) restricts candidates to qualified_name == "<enclosing class>.<name>" (src/parser/relations/helpers.rs:158-200 → self_filter_candidates, src/indexer/pipeline/resolve.rs:1149). There's no walk up the inherits chain, so a self.helper() resolving to a base class, a mixin, or unittest.TestCase machinery matches nothing and the edge is dropped. These were extracted on base.
# mixin.py
class Base:
def helper(self): return 1
class Child(Base):
def run(self): return self.helper()base: Child.run -> Base.helper [extracted]
head: (no calls edges at all)
Restricted to cases provable from the index's own inherits edges (target's class is a transitive ancestor of the source's class), the corpus loses 2,096 true edges — a floor, since it only counts same-file inheritance with an indexed parent:
_pytest/_code/code.py: ExceptionChainRepr.toterminal -> TerminalRepr.toterminal
_pytest/capture.py: TeeCaptureIO.__init__ -> CaptureIO.__init__
_pytest/fixtures.py: TopRequest.addfinalizer -> FixtureRequest.addfinalizer
User-visible effect: impact Base.helper answers "0 callers / risk LOW" for base classes and mixins — precisely the symbols with the largest blast radius.
Suggested fix: when the direct Type.name filter comes back empty, walk the inherits closure of impl_type and retry per ancestor. If the closure is unresolved (external base class), fall back to the old bare-name/ambiguous behaviour rather than dropping. Dropping is only correct when you know the class owns the method.
2. A receiver variable whose name coincides with a module filename manufactures cross-module edges
filter_by_segment_chain (src/indexer/pipeline/resolve.rs:1105-1130) matches the leading Path segment against /{seg}.py, /{seg}.pyi, /{seg}/__init__.py. But CalleeQualifier::Path is produced for any unknown receiver (alpha.helper(), self.dep.helper(), cmd.run()), and nothing checks the segment is actually bound to a module by an import in scope. Any local, parameter or attribute whose name matches a .py basename binds the call to that file's members — at inferred, which impact counts.
# cmd.py
class Command:
def execute(self): return "wrong"
# builder.py
class Builder:
def execute(self): return "right"
def make_builder(): return Builder()
# app.py
from builder import make_builder
def go():
cmd = make_builder() # cmd IS a Builder
return cmd.execute()base: go -> Builder.execute [ambiguous] <- correct target present
go -> Command.execute [ambiguous]
head: go -> Command.execute [inferred] {"q":"path","v":"cmd"} <- only the wrong one, promoted
refs Builder.execute now answers "no callers"; refs Command.execute names a caller that doesn't exist. At corpus scale, 6,460 q:path edges have a target whose file basename equals the segment and a source file that does not import it; 1,705 of those cross top-level packages:
_pytest/_code/code.py :: ExceptionInfo.exconly -> pip/_vendor/rich/text.py :: Text.rstrip
_pytest/_io/pprint.py :: PrettyPrinter._repr -> passlib/context.py :: CryptContext.copy
A text.rstrip() on a local string becomes an edge into rich/text.py. This is the failure mode src/indexer/pipeline/python_modules.rs:20-23 singles out as this repo's worst — "a phantom bound to a real node ... precisely because nothing in the answer says it is wrong" — and it's now at a tier counted by default.
Suggested fix: only treat a leading Path segment as a module reference when find_python_import_binding(scope, segment) returns a binding with is_module_import == true. The rewrite at index_files.rs:1430-1447 already computes exactly that. With no such binding the segment is a runtime receiver: keep the old bare-name/ambiguous behaviour, but don't path-match it against filenames.
3. INDEX_VERSION is not bumped
src/domain.rs:356 is unchanged, and the repo's own index_version_guard fails on this branch and states the decision rule. The answer to its question is unambiguously yes — 529,593 → 197,835 edges on identical input. Measured consequence: a base-built index queried by the head binary reports healthy and serves the old graph, then goes half-and-half after a single edit:
$ cg-head health-check # base-built index
OK: 37 nodes, 29 edges, 9 files <- no staleness signal
$ cg-head incremental-index # after touching ONE file
Incremental index: 1 files updated
# untouched file: old rules, cross-class phantom retained
# edited file: new rules, {"q":"path","v":"Alpha"}
One index, two resolution regimes, no signal. Fix: bump to 71 with a note on the constant naming what moved, then UPDATE_EXTRACTION_FINGERPRINT=1 cargo test --test index_version_guard.
4. The branch is CI-red
Note first: this repo requires maintainer approval for workflow runs on fork PRs, so CI has never run on this branch — the only green check was CodeRabbit. Locally:
tests/import_axis_parity.rs:237fails.python_import_metadata(src/parser/relations/imports.rs:863-877) now emits"is_module_import": falseunconditionally onfrom X import Ysymbol rows; that test asserts the key is absent there.cargo fmt --all -- --checkfails: 49 diffs across 12 files, all PR-touched.
Everything else is green (1,142 lib + 335 cli_e2e + 77 integration + 25 integration_call_qualifier), and cargo clippy --all-targets -- -D warnings is clean.
Fix: the consumers read the flag as .and_then(as_bool).unwrap_or(false), so false and absent are behaviourally identical — but the key is also stored in edges.metadata, which participates in idx_edges_unique, and emitting it produces a duplicate module-import edge in one case. Omitting the key when false fixes the test and the duplicate together. Then cargo fmt --all.
High
-
self.method()fans out to same-named classes in unrelated packages.self_filter_candidatesfilters byqualified_nameacross the whole project with no file/module scoping, soself.parse()inside babel'sLocalealso binds tomkdocs/utils/babel_stub.py::Locale.parse.refs Command.run --file setuptools/_distutils/cmd.pygoes from 33 references (15 caller files) on base to 60, including pip's unrelatedCommand. Suggest scoping to same file, then same package, before any fallback. -
CLI
refs/callgraph/impactlost the qualified→bare-name fallback (refs.rs:265-291,callgraph.rs:83-115,impact.rs:77-113). All three now branch onraw_symbol.contains('.')and require an exactqualified_name;resolve_qualified_symbol(src/cli/symbols.rs:137-162) documented and did the opposite. This is language-agnostic and hits Rust/TS/JS users too — on this repo's own index:[base rc=0] refs health.probe -> 4 references to 'probe' [head rc=1] refs health.probe -> Symbol 'health.probe' not found in index. [head rc=1] callgraph freshness.disclose -> ... the index may be stale — run `incremental-index`The reindex hint is what
callgraph.rs:213-217's own comment says the gate exists to prevent, andshowkept its fallback, soshow health.probesucceeds whilerefs health.probefails on the same binary. Suggest mirroringshow: exact qualified match first, fall back to the base-name path, and gate the hint on the base name being absent. -
The local-shadowing guard over-collects and has no test. Two independent problems in
index_files.rs:1362-1367:collect_identsrecurses the whole assignment LHS, soself.compute = 1registerscomputeas a local (andd[key] = vregistersdandkey); andwalk_python_scopeswrites each method's locals under bothClass.methodand the baremethod, so a module-levelprocess()inherits the locals of everyX.processin the file. Either makes the guardcontinue, dropping a trueextractededge before resolution. Single-variable pairs:self.compute = 1; return compute() base: Engine.run -> compute [extracted] head: (none) self.total = 1; return compute() base: Engine.run -> compute [extracted] head: same [extracted]Neutering the guard leaves the whole suite green, so the line is uncovered.
Medium / Low
- The builtin-name filter suppresses user-defined symbols reached without an explicit named import — the list includes
id,type,input,filter,map,set,list,format,open,next,super. Suggest gating on "no unique project definition of this name". - Duplicate module-import edge when a file uses both
import X as Yandfrom X import Z(same root cause as #4). impact --jsonchanged its"symbol"field without a note.python_localrecords the wrong binding for a plain dotted import.- Coverage gaps line up exactly with the defects above.
- (Low) Two load-bearing comment blocks deleted with no code change; some dead code and a third divergent qualifier rule;
get_node_ids_by_qualified_nameomits the<external>exclusion its siblings carry.
What I confirmed is working
I want to be clear that this isn't a wholesale rejection — a lot of it checks out:
- Non-Python extraction is untouched. Indexing this repo with both binaries: 12,361 → 12,354 edges, and every one of the 12 lost / 5 gained is Python. Zero Rust / JS / Markdown / JSON / Bash changes.
OR n.qualified_name = ?1does not fan out bare-name queries — the failure mode would need a node whosequalified_nameequals another node's barename; there is 1 such node out of 740 in this repo and 0 in the corpus, and the Rust qualified queries return byte-identical caller sets on both binaries.- The advertised precision wins are real: cross-class false positives (
Alpha.run -> Beta.helper) removed,selfbinding correct,from ... import Cache as NewCache; NewCache()resolving toCache. - Incremental indexing converges to a full rebuild, including through the changed
restore_inbound_edgesqualified-name path — verified for a content edit and for a class rename. - Ambiguity handling is sane: exit 1 with suggestions on both text and JSON paths,
--filedisambiguates, truncation disclosed. - MCP gained qualified-name support without losing anything — the fallback regression in #6 is CLI-only.
- Two of your new tests are not vacuous — mutating
matches!(receiver, "self"|"cls")andWHERE n.qualified_name = ?1each turns the intended test red.
Suggested order
- Bump
INDEX_VERSION+ re-record the fingerprint; omitis_module_importwhen false (clears both red test targets and the duplicate edge);cargo fmt --all. - Gate the
Pathfilename matching on a real module-import binding (blocker 2). - Walk the inheritance chain in
self_filter_candidates, and scope it (blocker 1 + high 5). - Restore the CLI fallback and the hint gate (high 6).
- Fix the two over-collections in the shadow guard, and cover the line (high 7).
- Gate the builtin filter on "no unique project definition" (medium 8).
Also worth rebasing onto current main when you pick this up — you're 33 commits behind, and only those two test files conflict.
Happy to go into more detail on any of these, and I can share the exact fixtures if that helps. Thanks again for putting the work in.

Thanks for the rebase onto v0.145.0 and for chasing the CodeRabbit findings down to
the last one. Both workflow runs are approved and green, so the mechanical gate is
clear and what follows is judgement.
Up front, because it is unusual and it is what made this reviewable: the PR respects
the invariants this repo paid for the hard way. Every new ambiguity envelope routes
through emit_exact_ambiguity / resolve::ambiguity_response with the cap and the
disclosure clause intact — no hand-rolled sixth wording. Every changed CLI path
re-resolves its target after a freshness refresh instead of re-running with a
pre-refresh node_id (SURF-16, the P0 of our last audit). The truncation plumbing is
untouched, no new bare transaction, and every new lookup is index-backed. That is
several traps not fallen into, and the shadowing test is the strongest new test in the
file.
Verdict: request changes. Four resolution defects, all reproduced against a
release build of b9112a3 and compared against v0.145.1, plus a set of contract
changes that need to reach the CHANGELOG.
Method: findings B1–B4 below were reproduced by building this branch
(cargo build --release --no-default-features) and running the fixtures shown. The
"should fix" items further down are code-read only and are labelled as such — please
push back where we have read them wrong.
Blocking
B1. The qualified path skips the test-symbol filter, so two surfaces disagree on one input
resolve::detect_ambiguity (src/resolve.rs:74-91) decides ambiguity over definitions
that are neither <external> sentinels nor test symbols. The two new qualified gates
count raw rows instead: src/cli/symbols.rs:171-191 (filtered only by --file, no
is_test_symbol anywhere in the file) and src/mcp/server/tools/refs.rs:110-137,
which short-circuits ahead of the test filter at :190.
Fixture — src/worker.py and tests/test_worker.py each holding class Worker with
def run. One index, one input, opposite verdicts:
$ code-graph-mcp callgraph Worker.run --json
{"error":"Ambiguous symbol 'Worker.run': 2 matches in different files. ...",
"suggestions":[{"file_path":"src/worker.py",...},{"file_path":"tests/test_worker.py",...}]}
# impact and refs: identical refusal
MCP find_references {"symbol_name":"Worker.run"}
-> {"error":"Ambiguous symbol 'Worker.run': 2 matches in different files. ..."}
MCP get_call_graph {"symbol_name":"Worker.run"}
-> {"function":"Worker.run","callers":[],"callees":[],"ambiguous_edges_hidden":1,...}
get_call_graph answers because it delegates to detect_ambiguity
(tools/callgraph.rs:143 → mod.rs:1430); get_ast_node does the same at :215.
We have shipped this exact defect three times (SURF-02, SURF-17, SURF-26): one input,
two surfaces, opposite verdicts. Please route the qualified gates through the same
filter, or lift the filter into the query.
Second-order: because the :110 branch returns test-path ids directly, the qualifier
becomes an undocumented third way to bypass the test filter — the error text at :190
advertises only node_id and file_path.
B2. Two plain dotted imports sharing a root component delete each other's calls
python_modules.rs:248 keys bindings on (scope, local_name), and imports.rs:686
derives local_name as name.split('.').next(). So import myapp.models and
import myapp.views both write ("<module>", "myapp") and the second overwrites the
first.
myapp/__init__.py (empty)
myapp/models.py def load(): return 1
myapp/views.py def render(): return 2
app.py import myapp.models
import myapp.views
def run():
myapp.models.load()
myapp.views.render()
v0.145.1: Full index: 4 files, 7 nodes, 4 edges
callgraph load --direction callers -> load (myapp/models.py) <- called by: run (app.py)
callgraph render --direction callers -> render (myapp/views.py) <- called by: run (app.py)
SELECT COUNT(*) FROM pending_unresolved_calls -> 0
this branch: Full index: 4 files, 7 nodes, 3 edges
callgraph load --direction callers -> load (myapp/models.py) [no callers]
callgraph render --direction callers -> render (myapp/views.py) <- called by: run (app.py)
SELECT COUNT(*) FROM pending_unresolved_calls -> 0
Swapping the two import lines swaps which call loses its edge — render goes dark
and load comes back, still 3 edges. That is last-import-wins on the shared key.
The base resolved this correctly (bare name, unique in the project), so this is a lost
edge rather than a precision trade — and the drop is silent: no pending row, nothing to
recover from on a later run. Even if you decide the strict binding is right, please
buffer a pending row instead of continue.
No existing test covers it. The parity test uses import pkg.api as api, which takes
the working explicit-alias branch, and
plain_dotted_module_import_requires_its_full_path (python_modules.rs:605)
hand-builds a single binding, so it cannot see a map collision.
B3. import pkg + pkg.sub.func() never resolves, and the pending row never drains
owner is taken as a class name, python_class_nodes(db, "sub") finds nothing,
resolve.rs:289 returns empty. module + "." + owner is never tried as a submodule.
pkg/__init__.py from . import sub
pkg/sub.py def func(): return 1
app.py import pkg
def run():
pkg.sub.func()
v0.145.1: 3 files, 6 nodes, 3 edges
callgraph func --direction callers -> func (pkg/sub.py) <- called by: run (app.py)
pending_unresolved_calls -> 0 rows
this branch: 3 files, 6 nodes, 2 edges
callgraph func --direction callers -> func (pkg/sub.py) [no callers]
pending_unresolved_calls -> func|{"module":"pkg","owner":"sub","q":"python_import"}
re-running incremental-index leaves the row (attempts=1)
Also uncovered by any existing test.
B4. The shadow model does not implement global/nonlocal, and leaks comprehension targets
collect_py_body_bindings (python_modules.rs:141,146) adds every
assignment / augmented_assignment left-hand identifier and every
for_statement / for_in_clause target to the function's local set. The words
global and nonlocal do not appear in that file.
db.py def process(x): return x
def connect(): return 1
comp.py from db import process
def run(items):
names = [process for process in items]
return process(1)
glob.py from db import connect
def reset():
global connect
connect = None
return connect()
v0.145.1: process (db.py) <- called by: run (comp.py)
connect (db.py) <- called by: reset (glob.py)
this branch: process (db.py) [no callers]
connect (db.py) [no callers]
Python 3 comprehensions have their own scope, so [process for process in items] does
not bind process in the enclosing function and process(1) still refers to the
import. global connect means the assignment does not create a local. The shadowing
test currently asserts a comprehension target shadows, so that case pins semantics
Python does not have.
Both directions fail closed (drop the relation), so the cost is missing edges rather
than wrong ones — which is the better failure mode, but it is silent in all four cases
above.
Should fix before merge (code-read, not reproduced)
S1 — the pending sweep now does per-row DB work for qualified Python rows.
resolve_pending_calls runs whenever a run indexed ≥1 file (index_files.rs:2597) and
sweeps the whole table; that part is pre-existing and not yours. What changed is the
per-row price: the if candidates.is_empty() { continue; } early-out is gone
(resolve.rs:534). Bare rows with NULL metadata still cost nothing, and
python_imported_call_candidates returns before any query for an external module. The
affected class is Python pending rows carrying a self/stype/rtype/path
qualifier with zero same-name candidates: python_typed_method_candidates calls
python_class_nodes as its first statement with no guard ahead of it, so each costs
1–2 uncached conn.prepare + query plus a possible inherits BFS, every sweep, until
eviction at 50 attempts. The PR also enlarges that population — pending_metadata
(index_files.rs:3437) is cleared only in the Chain/Receiver arm, so an unresolved
typed Python call now buffers with its qualifier attached. We have not measured the row
count and are not claiming a number; restoring the early-out ahead of the new arms is
cheap either way.
S2 — a second full Python module map per interactive edit. resolve.rs:460-470
rebuilds build_python_module_map over every Python file inside the sweep, duplicating
the map index_files already built in the same run (index_files.rs:2326). Please
pass the existing one in. Context for why we are picky: v0.145.0 bounded the global
edge post-passes to what a run disturbed, taking a one-file edit on django from
1,079 ms to 513 ms, and S1/S2 both sit on that path. The scoping itself does look
preserved — cg_scope_paths is widened by deferred.iter().map(|d| d.rel_path) and
every new deferral originates in a file already in the run.
S3 — impact's qualified-miss envelope silently lost candidates and the
Defined in: hint. The new early exit at impact.rs:82-99 pre-empts the richer
envelope. Those two are what a caller uses to recover from a mistyped qualifier, and a
consumer reading .candidates now gets null. Keep the key or list it as a removal.
S4 — one input, three spellings of "symbol". refs --json and callgraph --json
now echo the qualified input; impact --json echoes the bare tail via a binding added
for that purpose (impact.rs:103 → :349, :394). Both are pinned by cli_e2e.rs,
so either rule costs a test move. We do not mind which — we mind that it is one rule.
Tests
Two holes, both on the builtin rule:
integration_call_qualifier.rs:1846assertspython_call_edges(&db,"print").is_empty().
No fixture definesprint, and unresolved Python calls are never bound to
<external>sentinels, so that JOIN cannot return a row whatever the production
code does. Deleting the whole builtin arm atresolve.rs:406leaves it green.resolve.rs:407issame_language_candidate_count != 1, but no fixture defines a
builtin name twice, so mutating!= 1to== 0stays green. The over-fire
direction the condition exists to prevent is untested.
On test_incremental_rename_converges_to_full_rebuild (pipeline/tests.rs:3758):
flipping that assertion is right — the old expectation pinned a bare-name restore
stealing an unrelated definition, exactly the phantom this PR removes. But the fixture
now has no legitimate target after the rename, so the re-resolution path it was written
to guard is no longer positively anchored. Please add a rename case where a correct new
target does exist.
For the CHANGELOG "Upgrading" section
- Dotted input is matched against
qualified_nameexactly (one level,Class.method),
where it used to be stripped to the last component and used to derive a file filter. refs|callgraph|impact <Qual>.<name> --file Pexits 1 when<Qual>.<name>is not an
exact qualified name in P; refs/callgraph previously stripped and answered.- Qualified input with ≥2 exact matches → new ambiguous exit 1.
- Qualified input with exactly 1 match skips
detect_ambiguity, so input that used to
refuse as ambiguous now answers. - MCP
get_call_graph,get_ast_node,find_referencesnow resolveFoo.bar. - MCP
get_ast_node(include_impact=true)computes impact fromqualified_name, so
caller counts shrink to the specific method. refs --json/callgraph --json"symbol"now echo the qualified input.- Removed:
candidatesfromimpact's qualified-miss JSON, and theDefined in:
stderr line. - Removed: the
impactstderr note "<file>defines N symbols named<x>…". get_inbound_cross_file_edgesreturn tuple re-typed 5 → 6 fields.INDEX_VERSION70 → 71: every existing index rebuilds on upgrade. Justified —
import metadata is canonicalized before edge insertion andidx_edges_uniquekeys
onCOALESCE(metadata,''), so v70 and v71 rows would otherwise coexist as
duplicates for the same dependency.
One doc point: a deeper qualifier (module.Class.method, or Outer.Inner.method) can
never match, since the qualified name is built from the immediate parent only
(treesitter.rs:1040). Combined with (2), that turns a previously-working
refs/callgraph --file invocation into exit 1. Either accept deeper spellings or say
plainly that one level is the contract.
Happy to take B2/B3/B4 as a follow-up PR if you would rather land the qualified-symbol
work first — but B1 and the silent drops should not ship together, since a dropped edge
with no pending row is invisible to the user and unrecoverable on a later run. The
fixtures above are all four-file trees; each reproduces in under a second.

Gate the Python fallback ambiguity mark on the inserted target count.
Line 3687 tests python_candidate_count, which Line 3664 computes from the whole same-language pool. The insert at Line 3684 binds same_file_targets only. A single same-file target therefore becomes CONF_AMBIGUOUS whenever another same-language candidate exists in any other file.
classify_edge_confidence cannot repair that edge. Its CONF_WHERE requires src.file_id <> tgt.file_id, so a same-file edge is never reconsidered. The default confidence floor then hides a precise edge from callgraph and impact.
The pending sweep already uses the correct gate. resolve.rs Line 727 tests refined.len() > 1, which is the count of the targets it actually inserted. Apply the same rule here.
🐛 Proposed fix
- if python_runtime_fallback && python_candidate_count > 1 {
+ if python_runtime_fallback && same_file_targets.len() > 1 {
mark_call_edges_ambiguous(db, &source_ids, &same_file_targets)?;
}python_candidate_count then becomes unused and can be removed with its computation at Lines 3663-3667.

Compare the complete edge sets in the restored-target arm.
The fixture contains an explicit from db import save binding, so it exercises both imports and calls. The incremental pipeline restores inbound non-call relations through the deferred pass. Filtering the final parity check to REL_CALLS can hide a divergence in the imports edge.

Reuse the candidate rows for ambiguity suggestions.
selectable_qualified_definitions returns complete NodeWithFile values. The current code discards their fields and performs one get_node_by_id query per candidate. The ambiguity response caps suggestions at five, but the extra lookups are not capped. A secondary MCP reader can also observe a primary reindex between these statements, causing missing candidates to be omitted.
Map the returned candidates directly:
- let qualified_matches =
+ let qualified_matches =
if let Some(symbol_name) = symbol_name_arg.filter(|s| s.contains('.')) {

global_rebind assigns the module-level run name to a lambda before calling it. collect_python_local_bindings removes global names from its local set, so python_import_is_shadowed falls back to the from lib import run binding and creates an incorrect edge to lib.run.
Track function names that are declared global and assigned, separately from ordinary local bindings. Make python_import_is_shadowed reject module-level import resolution for those names. Keep global_rebind out of imported_callers.

Thank you for the rebase and the follow-up round — S1 through S4 are all genuinely addressed, and I verified each one rather than taking your summary at its word. CI is green 9/9 now that I approved the fork workflow runs; sorry that approval took as long as it did.
Two independent reviewers went over this with empty context, one on the indexer/resolution surface and one on the CLI/MCP surface, each in its own worktree. I then re-ran everything I am asking you to change, against your head 68d2f60 and against a merge-base build, so the blockers below are things I reproduced myself rather than things I was told. Where a claim turned out to describe pre-existing behaviour, I say so and I do not ask you to fix it.
Your four items first, because they are all good news:
- S2 (shared-root dotted imports) — fixed and order-symmetric. Six import orders produce identical edge sets.
- S3 (
import pkg+pkg.sub.func()) — resolves, and the pending table drains to 0. - S4 (
global/nonlocal/ comprehension) — all three fixed, and genuinely guarded: three separate single-variable mutations each turnpython_binding_patterns_shadow_imports_without_attribute_false_positivesred. - S1 (qualified CLI/MCP split) — fixed on both surfaces. Driving the real stdio MCP server rather than a test harness,
refs Worker.runandfind_references{"symbol_name":"Worker.run"}return the identical single reference,node_id 4, and the explicit--file tests/...request returns the identicaltest_caller,node_id 8, on both.
INDEX_VERSION 72 is correct and needs no re-bump for the merge itself — main has no src/ change since our merge-base, only tests/doc_cli_alignment.rs. The extraction fingerprint matches and will still match post-merge. The rebase gap I was worried about is not one: you add no clap flags and touch no steering doc, and your head passes doc_cli_alignment 7/7. (B1 below will probably move the fingerprint again — see the note at the end of it.)
Blocking — I reproduced each of these
B1. The project-builtin fast path drops call edges on an incremental index that a rebuild has
src/indexer/pipeline/resolve.rs, the if candidates.is_empty() fast path. On main this was continue — leave the row buffered. It now deletes the pending row when the target name is a Python builtin. That destroys the only recovery channel before a project definition of that name can arrive.
pass 1 caller.py: def call_it(): return open("x")
pass 2 add shadow.py: def open(path): return 8
Indexed incrementally, then the identical final tree indexed from scratch into a separate database:
| name | merge-base inc/full | your head inc/full |
|---|---|---|
open |
1 / 1 | 0 / 1 |
len |
0 / 0 | 0 / 1 |
compile |
1 / 1 | 0 / 1 |
format |
1 / 1 | 0 / 1 |
Please read the base column carefully. An earlier draft of this review had it as 0/0 across the board and concluded that you had simply not wired a new feature into the incremental path; that reading was wrong, and I am spelling out the correction so you don't chase it. For open, compile and format the merge-base resolved the edge on both paths. This is a regression on the incremental path against edges that used to appear, not an unwired feature. len is the only name where the base was 0/0, and only because it was already in CROSS_FILE_CALL_NOISE — generalising from it is exactly what produced the wrong reading.
It self-heals if the caller's own file is later touched, with nothing prompting that. That is the signature of the defect this repo bumped INDEX_VERSION to 71 for in v0.147.0: an incrementally grown index carrying fewer edges than a rebuild of the same tree, invisibly. python_project_builtins_win_only_when_uniquely_defined only exercises run_full_index, so nothing catches it.
Either keep buffering builtin-named rows and let the attempts ladder evict them — that is what the ladder is for — or drop the project-builtin feature. Shipping it on one path only is the shape we spent a forced re-index closing.
One heads-up: whichever way you go, this is likely to change what gets extracted or resolved, so expect the extraction fingerprint to move again and INDEX_VERSION to need another bump on top of 72. Better to find that in your next push than in CI.
B2. The S2 fix has no test that can fail
tests/integration_call_qualifier.rs:1702, python_shared_import_roots_and_package_submodules_all_resolve.
One-variable mutation at src/indexer/pipeline/python_modules.rs:287, restoring last-write-wins — i.e. reintroducing the S2 defect exactly:
- let coexist = binding.is_module_import && !binding.is_explicit_alias;
+ let coexist = false;With that applied: integration_call_qualifier 33 passed, integration 78 passed, cli_e2e 338 passed. 449 of 449 green.
The mutation is not inert — I checked, because a surviving guard usually means a weak mutation rather than a weak test. On a fixture with only the two dotted imports and no bare import pkg:
# app.py
import pkg.models
import pkg.views
def run():
pkg.models.load()
pkg.views.render()mutated binary → 3 edges, run -> render only. Unmutated → 4 edges, both load and render. Distinct binaries, md5 a972e6d9… vs 98af7f91….
The existing test survives because of its third import line, the bare import pkg. Under last-write-wins that is the binding that survives, and branch 2 plus promote_submodules then resolves all three calls through it — so the coexist logic is unnecessary for every assertion in the test. Please add a fixture with only the two dotted imports, asserting both edges, in both orders.
B3. A file path is now accepted as a symbol, and the command answers exit 0
Every file gets a <module> node whose qualified_name is the file path, which contains dots. select_cli_symbol (src/cli/symbols.rs:171) branches on raw_symbol.contains('.'), the module node matches exactly, and the result is ExactQualified — which suppresses both the fuzzy fallback and the not-found exit.
$ code-graph-mcp impact lib.py --json
merge-base: exit 1 {"error":"Symbol not found","symbol":"py"}
stderr: [code-graph] Symbol not found: py
[code-graph] If 'py' was added recently, the index may be stale — …
your head: exit 0 {"risk":"UNKNOWN","total_callers":0,…,"warning":"Impact analysis tracks …"}
stderr: (empty)
Same flip on refs and callgraph, and it is language-independent — the <module> qualified_name is the path for every language.
Two parts matter beyond the exit code. impact emits a risk verdict for an input it did not understand, which is the "safety endorsement handed to a typo'd path" shape this repo already fixed once, on the command our own decision table puts before an edit. And a script branching on exit status now takes the success path for a whole input class, undocumented.
Two things I want to be fair about: the "symbol":"py" mislabel is pre-existing — the merge-base prints it too, so that one is not yours. And refs <path> is not always a zero-reference answer; on my Python fixture it returned a real imports reference to the importing module. The problem is not that the answer is empty, it is that a file path is answered as if it were a symbol.
No test in the PR covers a file path as the symbol argument.
B4. Nothing in the PR compares CLI output against MCP output for the same qualified input
That comparison is S1. Four new cli_e2e tests were added and all four are CLI-only, so the split verdict this PR exists to close is verified by hand and not by the repo. I am asking for this one as a blocker rather than a nice-to-have because without it the next refactor re-opens S1 silently — the same way the four legs above were each fixed once and then only held by a test that could actually fail.
One test asserting the two surfaces agree on a qualified name, with and without an explicit test-file selector, would pin it.
Strongly recommended — reproduced, but I can be argued out of it
R1. refs and impact/callgraph disagree about whether a test-file definition is in scope
Two files, each defining class Worker: def run, each with its own caller using Worker.run(None):
| command | merge-base | your head |
|---|---|---|
refs Worker.run --relation calls |
2 refs (prod + test) | 1 ref (prod) |
impact Worker.run |
total_callers 1, tests_affected 1 | total_callers 1, tests_affected 1 |
callgraph Worker.run --direction callers |
results 1, test_callers_hidden 1 | results 1, test_callers_hidden 1 |
So one input now gets three different accounts of the test file, where before it got one. selectable_qualified_definitions (src/resolve.rs) applies is_test_symbol when no --file is given, but the traversal seed in query_direction (src/graph/query.rs) is
WHERE (n.name = ?1 OR n.qualified_name = ?1) AND f.path <> '<external>'
AND (?2 IS NULL OR f.path = ?2)with no test filter, so the test file's own Worker.run seeds the traversal and contributes its caller. Scoping the seed with --file src/worker.py takes tests_affected from 1 to 0, which isolates it.
The call shape decides only whether the default confidence floor hides this, not whether it is there. With Worker.run(None) the edges are extracted and the divergence is visible at the default floor, no flag needed. With Worker().run() they land in the ambiguous tier — that reflects the unresolved receiver expression, not a fan-out; each caller still binds only to its own file's definition — and callgraph/impact hide them until --min-confidence ambiguous, at which point the identical numbers appear. Both shapes are ordinary Python.
It also contradicts the CHANGELOG line "refs, callgraph, and impact use the same qualified selection" — the selection helper is shared, the traversal seed is not. That line needs changing whether or not the behaviour does.
Why this is a recommendation and not a blocker: there is a legitimate counter-argument, that the seed is deliberately unfiltered so impact's risk number covers the test surface too — a caller in a test file is still work someone has to fix. I lean the other way, because the test file here defines its own Worker and renaming the production method does not touch it, so what impact counts is a caller of a different definition. But if you think the seed should stay as it is, say so and change the CHANGELOG line instead; I will not hold the merge on it.
One suggestion, offered as a direction rather than a prescription: having impact and callgraph traverse the node IDs the shared selection already produced, instead of re-seeding from the symbol string, would close this and B3 together — a <module> node would not survive an ID-based selection intended for callable targets.
Δ-contract inventory — please extend the CHANGELOG
Eight user-visible changes are not listed, and one listed line is contradicted by behaviour (R1). I reproduced the first; the rest come from the CLI/MCP reviewer and I have not re-run them myself:
- (reproduced) exit 1 → 0 for a file path passed as a symbol, on all three commands — B3.
callgraph --jsongained a top-levelsymbolkey on the success envelope. The CHANGELOG phrases thesymbolrule as if the field already existed on all three commands; forcallgraphit did not exist at all.refs <Class>.<method> --file <path>flipped exit 1 → 0 and error-envelope → success-envelope when the file holds two definitions sharing the bare name. The new behaviour is correct; it is the documentation that is missing, and a client keying onsuggestionsnow sees a different object.- CLI and MCP put different values in the same
symbolkey — CLI"run", MCP"Worker.run"— for the same input. The CHANGELOG documents the CLI half only. - Error envelopes echo the qualified spelling where success echoes the bare one. Defensible, but the documented rule is scoped to success.
impact'sDefined in:line is now sorted and deduped (one.py, two.pywhere the base printedone.py, two.py, two.py). An improvement, listed under "keeps … recovery hints", which reads as unchanged.refs <missing-qualifier> --filechanged error shape; thesuggestionskey disappears for that input.- Separately, and not yours: MCP's miss message for a qualified name defined only in a test file says "not found in index" for a symbol that exists, where the bare-name path says "all matches are in test/bench paths … pass node_id or file_path to bypass". Pre-existing on the merge-base. Mentioning it only because it sits next to R1.

One reviewer claim I checked and am withdrawing
An earlier draft of this review said the 147-name builtin list makes a single project def open capture every genuine builtin open() call site repo-wide, with a 95.9%-new-names figure attached. The merge-base captures all three of my call sites identically, so that behaviour is not yours, and the figure would have sent you after the wrong thing. What the PR does change is the two-definition case: the merge-base emits two ambiguous edges, your head emits none. Going from "ambiguous and disclosed" to "silently absent" is worth a CHANGELOG line, and it is a much narrower claim than the one I nearly sent you.
What I would like next
B1 and B2 are the two I would hold the merge on, with B3 and B4 close behind. R1 I would like, but I am open to argument — see the paragraph there. Everything else can be a CHANGELOG addition.
The work here is good and the safety fixes are real. callgraph Gamma.helper --file two.py returning exit 0 with two callers of a class that does not exist, now exit 1, is worth the whole review on its own — and the qualifier genuinely surviving into the traversal, so impact Alpha.helper and impact Beta.helper in one file each report their own caller instead of a merged pair, is the feature working as advertised.

Thanks for round three, and sorry for the silence on it — this reply is late because I spent it on something I should tell you about directly. I opened #49, and it contains your qualified-symbol work. The PR body credits you; this comment is me saying it to you rather than leaving you to find it. If you would rather I hold it until you have had a say, tell me and I will — nothing is merged. What #49 is, and why I split it#49 takes the qualified-symbol half of this PR — the CLI and MCP surfaces, The reason is convergence, not quality. Three rounds, twelve blockers, and none of them found by CI — round 3's B2 is the clearest statement of it: restoring the S2 defect with a one-line mutation left 449 of 449 tests green. Every finding so far came from me building two binaries, indexing the same tree twice and differencing edge sets by hand, which is not a cost your next push reduces. The qualified-symbol half is separable and done. The resolution half deserves to be reviewed against something mechanical. Separating it needed exactly one untangling: I also dropped The rebase gets easier, not harderI assumed out loud that #49 would leave you with a painful rebase, then measured it and was wrong. The eight A-side Two of your four blockers are gone
That leaves B1 and B2. And B1 now has a mechanical detector#49's other half adds two tests to Run against your head, on a 14-file fixture: A guard counting totals sees nothing there. And the second test reproduces B1 on its own, in 0.12s: The missing edge is And it says something good about your current head, which I want on the record. On that same fixture your changes are improvements: One honest limitation: the A correction from round 3I told you the extraction fingerprint would still match post-merge. That has gone stale: What I'm askingKeep this PR open and narrow it to the resolution half, rebased onto Three constraints from the three rounds, so they are design inputs rather than round-four findings:
And a fourth, from B2 and from my own regression above: mutation-verify each new guard in the direction that reintroduces the defect, and check the sibling paths of whatever you fixed. I declared B3 fixed and shipped it with one of five surfaces still open. If you would rather not carry it on, say so and I will take the resolution half from here with your commits and your authorship — it should not die on the vine either way. If I do not hear from you in the next couple of weeks I will assume that is where we landed and pick it up, rather than leaving this open indefinitely. |
