Summary

• Root cause of pretix's straggler page (a 40k-ref batch at 2.1–2.7s inside a 4.7s resolution): minified-bundle refs paying ~10× per-ref cost. fabric.min.js chunks ran ~950ms vs a ~90ms floor — names like t fetch candidate pools of thousands, and the retain/scope chain runs per candidate.
• ResolveRefIn gains generated (DB flag via readPendingBatch's files.generated JOIN + the same path convention generatedPredicateFor uses; TS path via generatedPredicateFor directly — identical union semantics on both feeds).
• match_by_exact_name_uncapped and match_fuzzy bail (return no name candidate → unresolved, never a truncated winner) when the pool exceeds GENERATED_NAME_POOL_CAP = 256 AND either the ref's file is generated-flagged OR the pool is ≥75% generated nodes. The artifact-dominated rule catches vendored-but-unflagged sources (d3.v6.js, fabric.js, pdf.worker.js); real big pools (Migration 428, __init__ 422, django.db 555) proceed untouched.
• 11 synthetic ResolveRefIn construction sites get generated: None (internal probes — no behavior change).

Measured (pretix, Bun)

• Exact graph parity: 32,799 nodes / 73,404 edges / 165,700 refs — identical edge-kind distribution vs the pre-change index.
• Pathological chunks eliminated: max per-chunk resolve 950ms → ~250ms.
• Honest limit: batch-4 wall is unchanged within noise (2.1→~2.7s) — the residual is ~19k vendored-JS refs at ~0.5–1ms each, spread across the d3/fabric/bootstrap cluster, not one pool. This PR bounds the worst case; it does not claim the batch win.
• Generated files still resolve 5,266 edges on pretix — a capped ref can only lose an edge when its name-match pool exceeded the bound; zero instances on pretix.

Test plan

• pretix full-index parity: identical node/edge/ref totals and edge-kind distribution
• kernel-resolve-parity, resolver-pool-sizing: 17 tests pass
• Kernel rebuild (quick profile) clean; cargo check 0 errors
• Reviewer: confirm the cap's decline-not-truncate semantics in names.rs

Summary by CodeRabbit

• Bug Fixes
  • Improved reference resolution when many same-name matches come from generated or minified files. In these cases, the system now leaves the reference unresolved rather than choosing from an overly large candidate pool, reducing the risk of incorrect matches.
  • Corrected source-location information used during certain lookups, helping references resolve against the appropriate position.

Walkthrough

The resolver input now carries generated-file status from the TypeScript and Rust paths. Exact-name and fuzzy-name matching limit oversized candidate pools under generated-source conditions. A separate Lua-local reference construction now includes the candidate’s starting column.

Changes: Generated-aware name resolution

Layer / File(s)	Summary
Carry generated status into resolver references codegraph-kernel/src/resolve/mod.rs, codegraph-kernel/src/resolve/{declarations_upstream,fields,go_asserted,js_objects_upstream,kotlin_calls,kotlin_type_scope,names,resolver_upstream,rust_paths}.rs, src/extraction/kernel/loader.ts, src/resolution/index.ts	ResolveRefIn gains an optional generated field. The pending-reference query and TypeScript kernel path supply generated status, and resolver-created references initialize the field. The Go asserted initializer is unchanged.
Bound generated-source name pools codegraph-kernel/src/resolve/names.rs	Exact-name and fuzzy-name matching return unresolved when the candidate pool exceeds 256 and the reference is generated or at least 75% of candidates are generated.

Lua-local reference coordinates

Layer / File(s)	Summary
Set the Lua-local reference column codegraph-kernel/src/resolve/php_scope.rs	is_lua_local sets the synthetic reference column to the candidate’s start_column.

Priority: Low

Merge Risk: Low · previous review a4ccf

Some generated-file references may still encounter oversized name-match pools. This is a bounded performance risk; the change is mergeable with owner awareness or a follow-up fix.

- Line 1096: Update the `files` join on `unresolved_refs` to use the stored
`file_path` when present and otherwise the origin node’s path, so
`files.generated` reflects the effective reference path even when `file_path` is
empty.
