Lands the qualified-symbol half of #44 on main, plus two guards that make Python resolution changes visible.

Why this is split out of #44

#44 has had three review rounds and twelve blockers, none 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. The qualified-symbol work is separable, language-agnostic, and done; the Python resolution rewrite is where every non-converging blocker lives. This PR takes the first half so the second can be reviewed against constraints rather than discovered a round at a time.

The separation needed exactly one untangling: get_inbound_cross_file_edges had grown a sixth tuple element serving the incremental-restore path in index_files.rs — a resolution-side feature living in a storage-query file. Reverted to main's shape here. Also dropped get_node_ids_by_qualified_name, which has no production caller anywhere in #44 (only a unit test and the mod.rs re-export, which is what made it read as covered).

What changed

  • refs / callgraph / impact and MCP find_references / get_ast_node / get_call_graph take an exact qualified_name first, falling back to the bare name — what resolve_qualified_symbol already documented.
  • A file path is no longer accepted as a symbol. Every file has a <module> node whose qualified_name is its path, so impact lib.py answered exit 0 with a risk verdict for an input it never resolved. Module rows are excluded; the answer is byte-identical to 0.151.0 again.
  • tests/edge_coverage.rs gains a per-tier histogram and an incremental-vs-rebuild check. The existing baseline was calls(lang) >= 1, which no realistic regression breaches and which cannot see relabelling at all — and impact/callgraph default to a --min-confidence inferred floor, so a relabel moves an edge between hidden and counted with the total unchanged.

Contract changes

Both are in the CHANGELOG:

  1. callgraph --json gains a top-level symbol key on the success envelope.
  2. refs <Class>.<method> --file <path> exits 0 with a result where it exited 1 with suggestions, when that file holds two definitions sharing the bare name.

Evidence

  • 1,853 tests pass, 0 fail, across 28 suites (cargo test --no-default-features); clippy --all-targets -D warnings clean on both feature legs; fmt --check clean.
  • Five new tests, each mutation-verified in the direction that reintroduces the defect it guards — removing the module-row exclusion, desynchronising MCP's qualified path from the CLI's, relaxing the two-definition ambiguity check, and deleting the qualified-to-bare fallback each turn exactly one red.
  • The two guards were written against feat: Python call precision improvements and qualified symbol resolution #44's head as a live candidate: the histogram reports ambiguous 4 -> 2, inferred 4 -> 6 with the call total unchanged at 9, and the convergence check reports incremental {ambiguous: 2} against rebuild {ambiguous: 2, inferred: 1}. Both green here.
  • INDEX_VERSION (71), schema (v10) and the extraction fingerprint are untouched — no extraction source is in this diff.

Not covered

query_direction's traversal seed still matches the symbol string with no test-symbol filter while selectable_qualified_definitions applies one, so refs and callgraph/impact can still disagree about whether a test file's same-named definition is in scope. The selection helper is shared; the seed is not. The CHANGELOG states this rather than claiming otherwise.

Credit for the qualified-symbol design and implementation goes to @pabx06 in #44.

📝 Walkthrough

Walkthrough

The change adds exact qualified-name resolution with bare-name fallback across storage queries, CLI commands, MCP tools, and graph traversal. It adds file filtering, ambiguity handling, refresh revalidation, qualified output support, and regression coverage.

Changes

Qualified Symbol Resolution

Layer / File(s) Summary
Lookup and resolution contracts
src/storage/queries/*, src/resolve.rs
Exact qualified lookups exclude module and external rows. Dotted symbols use exact matches before bare-name fallback. Definition filtering and ambiguity detection support qualified names.
CLI selection and command execution
src/cli/symbols.rs, src/cli/commands/refs.rs, src/cli/commands/callgraph.rs, src/cli/commands/impact.rs
The CLI uses typed symbol selection for qualified and bare inputs. Commands handle ambiguity, file filtering, refresh revalidation, not-found output, and bare output symbols.
MCP and graph lookup paths
src/mcp/server/tools/*, src/graph/query.rs
MCP reference and AST-node tools accept qualified names. Graph traversal seeds exclude module nodes and accept qualified or unqualified names.
Regression coverage and release notes
tests/cli_e2e.rs, tests/edge_coverage.rs, tests/integration.rs, CHANGELOG.md
Tests cover qualified selection, CLI/MCP agreement, module-name rejection, edge-resolution identities, and incremental indexing. The changelog documents the release behavior.

… get_call_graph does not use it

CodeRabbit caught this on #49 after I had already declared the file-path defect
fixed, and it was a regression this branch introduced.

Excluding `<module>` rows from `get_nodes_with_files_by_qualified_name` covers
every surface that resolves through `select_cli_symbol` or
`selectable_qualified_definitions` — the three CLI commands, MCP
`find_references`, MCP `get_ast_node`. It does not cover MCP `get_call_graph`,
which seeds its traversal straight off the symbol string through three
predicates in this file. So the same input got a refusal from two MCP tools and
an empty-but-successful call graph from the third:

  main         get_call_graph{"symbol_name":"uniq.py"}
               -> Error: Symbol 'uniq.py' not found in the index
  this branch  -> {"callees":[],"callers":[],"direction":"callers",
                   "function":"uniq.py"}
  with fix     -> Error: Symbol 'uniq.py' not found in the index

That is the one-input-two-verdicts shape this repo has shipped three times
(SURF-02, SURF-17, SURF-26), and my own CLI-vs-MCP comparison test did not catch
it because it compares `refs` against `find_references` — the two surfaces that
were already refusing correctly.

`mcp_tools_agree_that_a_file_path_is_not_a_symbol` drives all three MCP tools on
one path input and asserts all three refuse, with a control arm asserting
`get_call_graph` still answers for a real qualified name so the guard cannot
pass by breaking call-graph lookup outright. It is red without this fix.

Also: the doc comment on `get_inbound_cross_file_edges` still described the
six-field shape from the branch this work was split out of, while the signature
here is five. Corrected to match the code.

Checked: 1854 passed, 0 failed, 28 suites; the six CLI arms (three commands x
path/qualified) and all three MCP tools verified against a main-built binary on
the same fixture.

…ation

The baseline here asserted `calls(lang) >= 1`. That is a floor no realistic
regression breaches — a change dropping 62% of a 500k-edge corpus still
satisfies it — and it is blind to relabelling entirely, because a relabel moves
no count it looks at.

Relabelling is the expensive shape. `impact` and `callgraph` default to a
`--min-confidence inferred` floor, so an edge moved `ambiguous` -> `inferred`
goes from folded out of risk scoring to counted by it, and the reverse silently
leaves every default-flag answer. The total is identical either way.

Two tests pin what the total hides:

- `python_resolution_tier_inventory_is_pinned` — an exact
  `(relation, confidence)` histogram over one fixture holding the Python call
  shapes that actually get edited: an inherited `self` call, a same-named method
  on an unrelated class, a receiver named like a module file, an aliased class
  import, two dotted imports sharing a root, and a project function shadowing a
  builtin. Main's values are calls ambiguous 4 / extracted 1 / inferred 4,
  imports extracted 8, inherits extracted 1, and the pending-call backlog is
  pinned in the same test at 1 (`build -> NewCache`, the alias this extractor
  never binds) — because an edge missing from the histogram was either dropped
  or is still buffered, and those two call for opposite responses.

- `python_resolution_converges_incrementally_to_a_rebuild` — a two-pass
  incremental index against a one-shot rebuild of the identical tree. This is
  the shape INDEX_VERSION has been bumped twice for: an index grown
  file-by-file carrying fewer edges than a rebuild, invisibly, because every
  single-path test agrees with itself.

Both were written against a real candidate change rather than in the abstract:
on an out-of-tree branch that rewrites Python resolution, the first reports
ambiguous 4 -> 2 and inferred 4 -> 6 with the call total unchanged at 9, and the
second reports incremental `{ambiguous: 2}` against rebuild
`{ambiguous: 2, inferred: 1}`. Both are green on this commit.

A failure in either is not by itself a regression. It means resolution moved and
the diff names which tier, which is the question a reviewer otherwise answers by
building two binaries and differencing edge sets by hand.

`Alpha.helper` and `Beta.helper` in one file were one symbol as far as the CLI
was concerned. Every command stripped the qualifier and looked up `helper`, so
the answer merged both classes' callers — or refused as ambiguous and offered
`show --node-id <N>`, an escape hatch that answers a different question: `show`
prints a definition, and the question was about callers.

`refs`, `callgraph` and `impact`, and the MCP tools `find_references`,
`get_ast_node` and `get_call_graph`, now try an exact `qualified_name` match
first and fall back to the bare name when nothing matches, which is what
`resolve_qualified_symbol` documented all along. `--file` narrows the qualified
match; two files defining one qualified name refuse with both paths named.

The fallback is load-bearing and nothing pinned it. Losing it would be a
language-agnostic regression — `refs health.probe` on a Rust or TypeScript index
where `health` is a module, not a type — so it has its own test, and the
stale-index hint stays gated on the BARE name being absent rather than firing
for a name the index does have.

A file path is not a symbol. Every file carries a `<module>` node whose
`qualified_name` is its own path; a path contains dots, so exact-qualified lookup
matched one, and `impact lib.py` answered exit 0 with a `risk` verdict for an
input it never resolved — on the command this project's routing table puts
before an edit. Module rows are excluded from qualified lookup, so a path is
back on the not-found path, byte-identical to 0.151.0.

Five tests, each mutation-verified in the direction that reintroduces the defect
it guards: removing the module-row exclusion, desynchronising the MCP qualified
path from the CLI's, relaxing the two-definition ambiguity check, and deleting
the qualified-to-bare fallback each turn exactly one test red. The CLI/MCP
comparison is there because the two surfaces were only ever exercised
separately, and this repo has shipped one-input-two-verdicts three times.

Two envelopes move: `callgraph --json` gains a top-level `symbol` on the SUCCESS
envelope, and `refs <Class>.<method> --file <path>` exits 0 with a result where
it exited 1 with `suggestions` when that file holds two definitions sharing the
bare name. Both are in the CHANGELOG.

Not covered, and the CHANGELOG says so: `query_direction`'s traversal seed still
matches the symbol string with no test-symbol filter while
`selectable_qualified_definitions` applies one, so `refs` and `callgraph`/`impact`
can still disagree about a test file's same-named definition. The selection
helper is shared; the seed is not.

INDEX_VERSION and the extraction fingerprint are untouched — no extraction
source is in this diff.

…ered about someone else

An independent reviewer with empty context found two regressions against main
and two holes in the guards this branch added. Its own five mutations (none of
mine) survived the suite four times out of five.

**A qualified name defined only in a test file lost its qualifier.**
`selectable_qualified_definitions` removed test definitions whenever `--file`
was absent. For a name that exists ONLY in a test file that leaves nothing, and
the caller then fell through to a bare-name lookup — so `refs TestHarness.run`
answered with an ambiguity error naming `Alpha.run` and `Beta.run` in a file the
user never mentioned, and offered `show --node-id 10` pointing at the wrong
symbol. All three commands flipped exit 0 -> 1. Reproduced on both arms before
fixing.

The reviewer noted the root cause better than the code did: `detect_ambiguity`
applies the same `is_test_symbol` predicate, but there it WIDENS what resolves —
a test namesake must not make your production symbol ambiguous. Applied to an
exact qualified lookup it NARROWS, and to nothing when the symbol is test-only.
Same predicate, inverted consequence.

Deleting the filter would fix it and re-open what the filter was added for, so
it now DEPRIORITISES instead: partition, prefer production, fall back to
test-only when production is empty. `--file` still bypasses entirely.

**The module exclusion was scoped too widely by my own earlier fix.** I had
written it as a conjunct over the whole seed predicate, which also blocks the
`n.name` leg — and a module node's name is the literal `<module>`, which main
answers with exit 0 and an empty result. Narrowed to the qualified leg only:

    WHERE (n.name = ?1 OR (n.qualified_name = ?1 AND n.type <> 'module'))

`callgraph '<module>'` matches main again, and MCP `get_call_graph` still
refuses a file path.

**Both new guards pinned counts, so a BALANCED tier migration was invisible.**
Swap one edge `ambiguous -> inferred` and another the other way and every count
is unchanged — while one edge silently enters every default-floor answer and
another silently leaves it, which is the exact scenario the tests' own comments
cite. `tier_histogram` is replaced by `edge_identities`, which returns
`relation confidence src_file:src_name -> tgt_file:tgt_name`; both tests compare
identity sets. Verified sensitive rather than assumed: applying that balanced
swap to the pinned set turns the test red and names both moved rows.

**`impact`'s excluded-caller disclosure on the qualified path had no guard.**
The suppressed-edge count seeds from a SEPARATE query, and reverting its
qualified clause makes `impact <Qualified>` answer `risk: LOW` with
`ambiguous_callers_excluded` and the "blast radius may be larger" note silently
absent — a cleared safety check that was never run. All 1853 tests stayed green
under that mutation. Now pinned, with a `--file`-disambiguated bare-name control.

Three findings are documented rather than changed, in the CHANGELOG: a third
contract item (`callgraph <dotted> --file` is now a strict miss where it fell
back), `refs` text-vs-JSON symbol spelling, and two mutation-surviving
behaviours that are not regressions against 0.151.0.

Checked: 1857 passed, 0 failed, 28 suites. Each new test mutation-verified in
the direction that reintroduces its defect.

…mbol broke a test-NAMED one

The round-1 repair partitioned qualified candidates with `is_test_symbol`, which
is name-OR-path. A PRODUCTION method called `test_step` is therefore classified
as a test symbol, and once a test-file twin exists the production side of the
partition is empty, the fallback returns both, and all three commands refuse:

    refs Job.test_step   main: exit 0 (prod_runner)  ->  repaired: exit 1
                         {"error":"Ambiguous symbol 'Job.test_step': 2 matches
                          in different files. Specify --file to disambiguate."}

A regression against main AND against this branch's own first cut. Reproduced on
both arms before fixing. `test_connection` / `test_mode` / `test_step` are
ordinary production helper names.

Partition on `is_test_path` instead. The name legs were wrong here twice over.
Substantively, production-wins is a claim about where a definition LIVES, not
what it is called. Structurally, every candidate in that vector shares one
`qualified_name` and a node's name is that name's last component — so the name
legs evaluate identically for all candidates and can only classify ALL or NONE.
NONE is a no-op; ALL empties `production` and produces exactly the failure above.
The predicate could not help and did hurt.

The round-1 control could not catch it: it used `Worker.run`, and
`is_test_symbol("run", "src/worker.py")` is false, so its partition behaved. The
fixture now carries a `test_`-prefixed production method beside the plain one,
and reverting the predicate turns it red on all three commands.

Also from the same round:

- `edge_identities` rendered bare names, so `Alpha.run` and `Beta.run` in ONE
  file were the same string — re-pointing a call from one to the other left the
  sorted output byte-identical. That is the target-side analogue of the balanced
  tier swap the round-1 repair closed, on precisely the same-file same-name
  collision this feature exists to resolve. Now `COALESCE(qualified_name, name)`,
  with a `module` arm so `<module>` rows do not render as `app.py:app.py`.
  The four `calls ambiguous` pins gain their qualifiers and are self-documenting.

- MCP `find_references` answers a qualified name defined only under `tests/`
  where the bare spelling returns the test/bench refusal. The answer is correct
  and matches the CLI on every arm, and `impact`/`callgraph` still route such a
  definition to `test_callers` with 0 contribution to the risk verdict — so this
  is documented in the CHANGELOG rather than changed. Worth knowing: the refusal
  message enumerates two bypasses and there are now three.

Checked: 1857 passed, 0 failed, 28 suites. The new control is mutation-verified
against the predicate it guards.

…hod it tests, and my reasoning said it could not

Round 2's repair partitioned on `is_test_path` alone, and I justified dropping
the name legs with a structural argument: every candidate shares one
`qualified_name`, a node's name is that name's last component, so the name legs
must classify ALL or NONE and are therefore inert. The reviewer found the
counter-example.

`parser::treesitter`'s `is_gtest` branch gives `TEST(Suite, Name)` the node name
"Suite.Name" AND the qualified name "Suite.Name". So a gtest case collides with
the method it exercises while carrying a DIFFERENT name — the exact shape the
all-or-none argument said could not exist. The premise holds everywhere else:
over this project's own index, 5,083 distinct qualified names, zero mapping to
more than one distinct name. C/C++ is the sole violator, and the branch had no
C++ coverage, which is why three review rounds and my own matrix all missed it.

The user-visible half is worse than the reasoning error, and it predates both
repairs — 9ac9164 shipped it:

    TEST(Widget, run)  vs  class Widget { int run(); }   # Google's own
                                                         # TEST(ClassUnderTest, method)
    refs/callgraph/impact Widget.run
      main     exit 0, resolves to the method
      9ac9164  exit 1  Ambiguous symbol 'Widget.run'
      fcac72f  exit 1  (unchanged by either repair)

Neither file is on a test PATH — `INFIX_TEST_EXTS` is go/rs/py/dart, not cc/cpp
— so no path heuristic separates them.

`node.is_test` closes it, and it is the right kind of fact: the parser sets it
from the AST, so it is authoritative where a filename is a heuristic. Verified
on three md5-distinct binaries against the same fixture: main exit 0, fcac72f
exit 1, this commit exit 0 on all three commands. Every D1/F2 behaviour survives
— the Python fixtures' nodes all carry `is_test = 0` and are caught by path, as
before.

`a_gtest_case_does_not_shadow_the_method_it_tests` is the first qualified-lookup
coverage in any language but Python. Removing the `is_test` disjunct turns it
red, and the failure prints the collision: `src/widget.cc` name "run" type
method, `src/widget_test.cc` name "Widget.run" type function.

The comment in `selectable_qualified_definitions` now records that the earlier
argument was wrong and where, rather than quietly stating the corrected rule —
the reasoning is what a future reader would otherwise repeat.

Also from the same round: the tier fixture asserts no file defines one qualified
name twice. `edge_identities` renders `file:qualified_name`, which Python's
platform-conditional `if/else def` idiom can make non-unique; the fixture has no
such pair today, and the assertion makes the day one appears a loud failure
rather than a silent loss of discrimination.

Checked: 1858 passed, 0 failed, 28 suites.

…xes are worse

Pre-ship review round 4 closed the enumeration: `qualified_name` doubles as
"Container.member" and as "this node's own name", so any node whose NAME carries
a dot occupies a `Class.method` spelling. Exactly three extractors produce one,
verified across all twenty supported languages — markdown headings, C/C++ gtest
cases, and bash functions. JS member and prototype assignment, TS namespaces,
Ruby `def self.x`, Go receivers and the rest all yield bare names; CSS, JSON and
HTML yield no symbol nodes at all.

Documented rather than patched, and the reason is measured rather than asserted.
A node-type list cannot express the class: bash's type is `function`, so a
denylist omits it and an allowlist must include it — both polarities leak
through the same producer. The predicate that does express it,
`name <> qualified_name`, was built and run:

    impact Widget.run   (bash `Widget.run()` + python `class Widget: def run`)
      0.151.0   callers [widget.py:caller]                     direct 1
      this PR   exit 1, Ambiguous — names both files, says --file
      candidate callers [deploy.sh:main, widget.py:caller]      direct 2, risk LOW

`query_direction` seeds on `n.name = ?1`, and a bash function's name IS the
dotted string, so the seed re-admits what selection excluded. The candidate
trades a loud refusal for a wrong blast-radius number, which is the worse
failure by this project's own bar.

The real fix is the entry already below this one: seed traversals from the node
ids selection chose rather than re-deriving from the string. Deliberate change,
not a release-eve patch.

…e asserting its own opposite

Three findings from a CodeRabbit review I had not read: I checked CI status after
that push and never went back for the review body, so these sat unread for an
hour. Its first review found the MCP seed hole that mattered most in this branch,
so that was a poor place to stop looking.

**The production-wins control was vacuous, and it guards D1 and F2.**
`a_production_definition_still_wins_over_a_test_namesake` asserted only exit 0
on both arms. If the default selection picked the TEST definition and `--file`
were ignored outright, both calls still exit 0 and the test passes while
asserting the opposite of its name. It now parses each response and asserts the
caller it must have found — `prod_caller` lives only in src/, `test_caller` only
in tests/. Verified by mutation: swapping the partition's preference turns it red
naming `test_caller`, which is exactly the state that used to pass.

**`callgraph --json`'s new `symbol` key had no test on its VALUE.** The envelope
is documented as echoing the bare name; nothing pinned it, so a change that
echoed the qualified input instead would have shipped unnoticed. Asserted, and
mutation-verified — `"symbol": symbol` in place of `output_symbol` prints
`Worker.test_step` and turns it red. (The first attempt at that mutation did not
compile, `-D warnings` on the now-unused binding; renaming the binding is what
makes it a result rather than a build failure.)

That closes one of the two mutation-surviving behaviours the CHANGELOG listed as
uncovered, so the entry now names only the post-refresh re-validation.

**The CHANGELOG said "five surfaces" and listed six.** Three CLI commands plus
three MCP tools take a symbol name. Corrected, with the six named rather than
counted, and the sibling sentence split so it says which test covers which half.

Checked: 1858 passed, 0 failed, 28 suites.

Exclude non-definition nodes from exact-qualified lookup.

get_nodes_with_files_by_qualified_name excludes only module rows. The parser also stores Markdown headings as h1–h6 nodes with qualified_name equal to the full heading text. If a heading is named Widget.run, the dotted lookup returns it with the real method whose qualified name is Widget.run. select_cli_symbol and MCP ambiguity handling then treat both rows as matches. Exclude h1–h6 at this shared query boundary. Do not use a narrow allowlist that drops supported constant, struct, interface, enum, trait, or type definitions.

Apply production-over-test filtering to qualified traversal seeds

When no explicit file selector is supplied, selectable_qualified_definitions keeps production definitions and drops test definitions when both share a qualified name. refs uses this result, but callgraph and impact pass the raw qualified name to the shared traversal, whose seed query matches both definitions. Apply the same production-over-test filter to qualified traversal seeds. Preserve the explicit-file bypass and the fallback to test definitions when no production definition exists.

CodeRabbit's third review asked for this at the shared query boundary, and it is
the one member of the dotted-name class that can be closed safely before a
release.

A markdown heading's `qualified_name` is its own text, so `## Widget.run` in an
API doc occupies the same spelling as the method `Widget.run`. Against a Python
`class Widget: def run`, `refs`/`callgraph`/`impact Widget.run` refused as
ambiguous where 0.151.0 answered. `## Class.method` is ordinary API-doc style.

`h1`..`h6` join the `<module>` exclusion in
`get_nodes_with_files_by_qualified_name`. Verified on three md5-distinct
binaries: 0.151.0 exit 0 → this branch before exit 1 → after exit 0, and `after`
matches base exactly rather than merely not refusing — `direct_callers` 1, caller
`drive`, same as 0.151.0.

**Why this one is safe when `name <> qualified_name` was not.** That predicate
was measured last round and rejected because `query_direction` seeds on
`n.name = ?1`, so excluding a node from selection while the seed re-admits it
trades a refusal for a wrong blast-radius number. A heading carries no edges, so
the seed re-admitting it contributes nothing and the answer is the base answer.
Bash is where that reasoning fails, and bash stays open and documented — its
node type is `function`, which no type predicate of either polarity can separate
from a real symbol.

Denylist rather than allowlist, deliberately: an allowlist that omitted
`constant`, `struct`, `interface`, `enum`, `trait` or `type_alias` for any of
the twenty grammars would silently stop resolving a real symbol, a worse failure
than the one being fixed. CodeRabbit asked for the denylist form for the same
reason.

CodeRabbit's other finding — apply production-over-test filtering to the
traversal seed — is NOT taken here. It is the architectural residual already
named in the CHANGELOG, and the same measurement above is why: touching the
selection/seed divergence piecemeal is what produces the over-count. Selection
and seed should agree by construction, via node ids, in a change of its own.

Checked: 1859 passed, 0 failed, 28 suites. The new test is mutation-verified —
dropping `h1`..`h6` from the predicate turns it red.

… get_call_graph does not use it

CodeRabbit caught this on #49 after I had already declared the file-path defect
fixed, and it was a regression this branch introduced.

Excluding `<module>` rows from `get_nodes_with_files_by_qualified_name` covers
every surface that resolves through `select_cli_symbol` or
`selectable_qualified_definitions` — the three CLI commands, MCP
`find_references`, MCP `get_ast_node`. It does not cover MCP `get_call_graph`,
which seeds its traversal straight off the symbol string through three
predicates in this file. So the same input got a refusal from two MCP tools and
an empty-but-successful call graph from the third:

  main         get_call_graph{"symbol_name":"uniq.py"}
               -> Error: Symbol 'uniq.py' not found in the index
  this branch  -> {"callees":[],"callers":[],"direction":"callers",
                   "function":"uniq.py"}
  with fix     -> Error: Symbol 'uniq.py' not found in the index

That is the one-input-two-verdicts shape this repo has shipped three times
(SURF-02, SURF-17, SURF-26), and my own CLI-vs-MCP comparison test did not catch
it because it compares `refs` against `find_references` — the two surfaces that
were already refusing correctly.

`mcp_tools_agree_that_a_file_path_is_not_a_symbol` drives all three MCP tools on
one path input and asserts all three refuse, with a control arm asserting
`get_call_graph` still answers for a real qualified name so the guard cannot
pass by breaking call-graph lookup outright. It is red without this fix.

Also: the doc comment on `get_inbound_cross_file_edges` still described the
six-field shape from the branch this work was split out of, while the signature
here is five. Corrected to match the code.

Checked: 1854 passed, 0 failed, 28 suites; the six CLI arms (three commands x
path/qualified) and all three MCP tools verified against a main-built binary on
the same fixture.
