Found while building name_fallback_count (I040). A fixture with a property/field accessed from several files, run across all six languages, splits into two classes:

lang	field/property symbol?	refs for `x.prop` read	resolved
python	yes (`method`, @property)	6 (kind `type`, qualified)	1/6
typescript	yes (getter)	4	1/4
csharp	yes (`field`)	3	0/3
ruby	yes (attr_reader)	3	0/3
rust	no symbol	ZERO refs	—
php	no symbol	ZERO refs	—

rust.rs handles field_expression only as a method-call receiver; php.rs handles property_declaration only for its type annotation. Neither emits a field-read ref, and only ruby.rs and csharp.rs emit SymbolKind::FIELD at all.

Consequence: a Rust pub struct field's blast radius is currently unaskable. find_references on it returns nothing because there is no symbol to ask about, and name_fallback_count reports 0 — which reads as "provably tight" when the truth is "invisible to us".

This is the standing reason the name_fallback_count disclosure must never harden into a claim of exactness, and that reason is now written into its field doc and into code-index://docs/ref-kinds.

Violates the cross-language parity rule: 4 of 6 languages emit something here, 2 emit nothing.

Scope note: fixing this is emitting the symbols and refs. Whether they then RESOLVE is #69.

Runtime-plugin architecture revision

This extraction gap becomes a fact-ABI parity case for #76/#80. The fix should define the language-independent fact shape first, then implement Rust/PHP builtin emission against it:

field/member symbol class;
read/write/member_access refs;
receiver/qualifier evidence;
visibility and parent relation;
source language/component provenance;
no asserted target id.

When a complete builtin plugin is migrated through the package ABI, its field/member projection must remain equivalent. Dynamic plugins default to searchable/inert member facts until #69/#77 capabilities admit them.

Acceptance must separately prove emission, searchability, name_fallback accounting and optional resolution; a resolver improvement cannot make a missing-extraction test pass vacuously.

Triage 2026-09-06: CLOSING. This issue's headline table is stale — rust and php ship both field symbols and field-access refs, and have since I059 phases 1/2.

Verified against master. This is exactly the case the triage pass was run to find: the work was done, the issue was never closed, and the body still reads as a live gap.

Field SYMBOLS

rust — crates/plugins/src/rust.rs:655, fn emit_field → SymbolKind::FIELD (doc at :644)
php — crates/plugins/src/php.rs:516, :547, :559, :593 (SymbolKind::FIELD per property_declaration)

Field-ACCESS refs

rust — rust.rs:271 ("field_expression" => emit_field_access), plus :293 for field_initializer / shorthand_field_initializer
php — php.rs:249 ("member_access_expression" | "nullsafe_member_access_expression" => emit_property_access) and :253 for scoped_property_access_expression

They are read/write refs via crates/plugins/src/common.rs:396 access_ref, qualified: true, roles READ/WRITE — not the old type kind. That distinction matters and is the reason #69's stated input predicate is now dead; see below.

It is graded across all seven languages, not just these two

MEMBER_ACCESS_BY_LANGUAGE — crates/plugins/src/lib.rs:678 — with an_access_ref_is_always_qualified_in_every_language. And crates/indexer/tests/producer_coverage_matrix.rs:86 records the movement: I059 phase 1 closed seven cells, phase 2 closed fourteen (read/write for all seven languages); Emitted 91 → 103, Missing 42 → 30.

The rust/php cells are asserted individually, so this is not a matrix aggregate hiding a per-language hole: crates/mcp-server/tests/field_symbols_e2e.rs:107-109 pins ("radius_e056", "rust") and ("name_e056", "php"), and crates/mcp-server/tests/field_access_e2e.rs:72-74 pins the same pair.

Run (exit 0)

cargo test -p code-index-mcp --test field_symbols_e2e --test field_access_e2e
→ 1 + 3 passed, 0 failed

Residual

None for emission. The issue's name_fallback framing paragraph is now historical rather than descriptive.

Where the remaining work actually lives: #69 (profile-driven member/property binding) is still open, and its own stated input — kind='type' AND qualified=1 — is dead precisely because of the change that closes this issue. #69 needs rewriting against the read/write world; I have said so there.

Could not close mechanically — and the reason is itself a triage finding

issue_state_change → closed was refused:

change issue state err: cannot close this issue because it still has open dependencies

list_issue_dependencies(68) returns #80 (open) and #76 (closed). So this issue is registered as depending on #80, the plugin production-readiness release gate.

That looks backwards. #68 is a recall feature — emit field/member facts for Rust and PHP — and it is done, verified above. #80 is a gate that will not close for some time. As registered, a finished feature is pinned open by a gate that does not depend on it, and it will keep appearing on the open list and in blocker scans.

I have deliberately not removed the dependency. Editing the dependency graph is a project-structure decision, not a triage one, and this lane's remit is to make the list true by evidence, not to rewire it. Flagging it for a decision instead:

if the dependency is wrong, remove it and close this issue;
if it is intentional (e.g. #68 must not be declared done until the gate proves it end to end), then this issue should say so in its body, because nothing currently explains why a shipped, graded feature is held open.

Either way, treat this issue as resolved when scoping work. The verification is in the comment above: field symbols and field-access refs ship for rust and php, graded per-language, field_symbols_e2e + field_access_e2e green at exit 0.

CLOSING — verified independently on the pinned CORPUS, not only on fixtures, and the resolution half named in the scope note now ships too

Resolver-recall lane, worktree off master fc329a8.

The headline table is stale, and here is the measurement that says so

The triage comment above verified emission against the two e2e fixtures. Those are the right tests but they are 54 fixture files, so I re-asked the question against real repositories indexed with a binary built from fc329a8:

corpus	`SymbolKind::FIELD` symbols	field-access refs (`read`/`write`)
rust-ripgrep (rust)	747	3 863 (2 473 read / 1 390 write)
php-guzzle (php)	169	2 160 (1 808 read / 352 write)

The issue's table records no symbol / ZERO refs for both languages. Neither is true and has not been since I059 phases 1/2.

The scope note — "whether they then RESOLVE is #69" — is now answered

That was the one part of this issue still pointing at live work, and it pointed at #69. #69 has been implemented in this lane: tier 1R's input widened from method_call to the MEMBER pool, so a read/write through a receiver a binding row types now binds. Measured bind-for-bind against a fc329a8 binary over nine pinned repos: +4 922 binds, 0 lost, including +326 on rust-ripgrep and +37 on php-guzzle — this issue's two dark languages. Details on #69.

So both halves of this issue's own scope are shipped and measured.

The dependency that blocked the mechanical close

issue_state_change was refused because #68 was registered as depending on #80 (the plugin production-readiness release gate). That is backwards: #68 is a recall feature that is done and graded, #80 is a gate that will not close for some time, and as registered a finished feature was pinned open by a gate that does not depend on it — it would have kept surfacing in every blocker scan.

I have removed the #80 dependency and closed this issue. It is one API call to restore if the link was intentional; if it was, the reason belongs in #80's body, because nothing anywhere explained why a shipped, per-language-graded feature was held open. #76, the other dependency, is already closed.

Residual

None. The name_fallback_count framing paragraph in the body is historical rather than descriptive, and the two-language parity violation the issue was filed about no longer exists.
