Calls through index.ts re-exports now reach the function's defining file. This covers renamed named re-exports (export { a as b } from './m') and export * chains, the cases in #2718 and #1557.

Credit

The first two commits are @antespi's from #2402 (index.ts barrels, dotted file names). I kept his authorship and sign-off unchanged. On October 4 you asked for #2402 to be split into focused PRs. This PR is only the barrel part, plus one commit of mine for renames and export *. @antespi, if you would rather land these yourself, I will close this PR. It only builds on your work.

One claim

This PR changes only TS/JS re-export resolution. It does not include the bare-specifier binding reported in #2869, and it does not change MCP output.

Reproduction

repro.sh (below) writes 6 files: a renamed re-export, an export * chain, and a decoy file with the same names. It uses its own cache and runtime folders.

main (812d075):

a statePath src/other/decoy.ts unique_name "0.38"
b loadThing src/star/thing.impl.ts suffix_match "0.55"

this branch:

a getStatePath src/lib/xdg-paths.ts import_map "0.95"
b loadThing src/star/thing.impl.ts lsp_ts_import "0.95"

repro.sh

#!/usr/bin/env bash
# Calls through index.ts re-exports: a renamed named re-export and an export * chain.
# Usage: bash repro.sh [path/to/codebase-memory-mcp]
# Uses its own cache and runtime folders, so an installed daemon or index is not touched.

Tests

New cases in tests/test_extraction_imports.c and tests/test_lsp_resolution_probe.c. On macOS arm64: scripts/test.sh --suites extraction_imports,edge_imports,path_alias,mcp,lsp_resolution_probe gives 625 passed, 4 skipped. The only failure in a wider run is regex_compile_refuses_overlong_pattern, which fails on main too (#2899).

Every commit is signed off. I have not seen CI on Linux or Windows yet.

[github-actions]

Thanks for opening this — it has been seen, and it is queued.

This note is automated, but it is not a brush-off: it exists so you know where your PR stands instead of having to guess from silence.

Current review status: working through a backlog. 0.9.1-rc.1 is out, so the release freeze that held reviews is over — but it left a large queue of open pull requests behind it, and we are reading through them oldest-first. The background is in discussion #1144.

What that means for this PR, concretely:

• It will not be closed for inactivity. No stale bot touches pull requests here.
• It may still sit a while before a human reads it. That is on us, not on you.
• Older PRs are read first, so a recent one is not being skipped — it is behind a queue.

Things that will genuinely speed it up whenever review does happen:

• Keep it rebased on main — the tree is moving quickly right now, and a conflicting branch cannot be reviewed as the diff you intended.
• Get CI green, or say which failures you believe are pre-existing.
• Keep the change to one claim. Bundled features and refactors get split before they get merged, which costs you a round trip.
• Every commit needs a sign-off (git commit -s) — CI enforces DCO.

If this fixes a bug, a reproduction we can run is worth more than a description of the symptom.

Thanks for contributing, and sorry in advance for the wait.
