Air-gapped source code examiner / Claude and I have been working over several weeks on a CodeExam tool, originally written in python, now ported to Node.js. I have a revised TODO list that I'd like to work through. There's more detail for each item, but roughly: 1. --build-index command should accept zip/7z/tar/gz/etc. archive files, and use them as basis for the index. If zips are encountered inside of zips, handle recursively. In pathnames in the index, include the zip's path/filename as the first part of the path/filename in the index. Separate the root zip path/filename from path/filename of zip's contents with a '!' delimiter I think. 2. Also for --build-index, when encountering binary executable files (.exe, .dll, .sys, .so, I think .pyd, .class, others), don't ignore as currently implemented. Instead, do the "binstrings" operation on each one to generate .op files to put into the index. I've upload binstrings_2.py to the project. I can upload a sample .op file too. It defaults to using Microsoft's vc++filt.exe to demangle C++ function strings, but that won't work for non-VC mangled C++ func sigs. Some executable formats are actually zip files (.apk I think?), and the files like .class inside them should be given this same treatment (though eventually .class would be decompiled into .java, using JADX or something). 3. Modify --index-path behavior to allow loading multiple indexes into same session, so that all cmds work across all the indexes. At some point, there will be new cmds to compare across indexes, but first iteration will just be getting multiple indexes to work together. 4. I think the Node.js port is not yet using tree-sitter. I think it's all custom regexes right now. Working very well, but we should at least have --use-tree-sitter option do the right thing in JS. 5. The multisect commands currently look for intersection of terms first in a single function, then across multiple functions in the same file, then across multiple files in the same subfolder. This should be modified to also look into single class, after single function/method, and before entire file. 6. Provide a command that shows all call targets, and indicates which are, or are not, inside the codetree. This is the opposite of the current --entry-points and --gaps commands. There will be issues with same-named call targets not being the same, because in different class etc. contexts. 7. I think there are problems now with function/method name ambiguities in cmds like --callees, --callers, --call-chain etc., where same-named functions/methods across classes/files are sometimes assumed to be referring to the same thing. Basically, the handling of overloaded names is somewhat naive. 8. Start moving to GUI. This is a big change. One possibility is HTMX. A friend of mine is working on something called XMLUI. I have notes for look and behavior I can share when we get to this -- likely not for a week perhaps. There's more, but enough for now as a roadmap for the next week of work. Let me know when you're ready the latest tarball (or let me know if you can already access it, code-exam-phase9d-novocab.tar, 675k, from today 02/23/2026), and then let's discuss before you start with task 1. I'll want you to check in with each after your completion of each task, and before starting next one. Show less 1:09 PM Excavated project history to contextualize revised development roadmap Excavated project history to contextualize revised development roadmap I'll start by searching past conversations to get up to speed on the current state of the CodeExam Node.js port, then check the project files. Assessed project context and verified latest tarball availability Assessed project context and verified latest tarball availability Now let me check if the tarball is available in uploads: Synthesized project status and prioritized tarball upload request Synthesized project status and prioritized tarball upload request Good — I'm now fully caught up on the project history. Here's my understanding of where things stand: Current state: CodeExam Node.js port, phase 9d, 284 tests passing, ~10K+ lines across 16+ source files, zero npm dependencies. Features include: literal/inverted/function index, callers/callees/call-chain, hotspots/metrics/classes, dedup (exact/structural/near), multisect-search, vocabulary discovery, claim-search/claim-analyze (both Claude API and local model), interactive REPL, streaming JSON for multi-GB indexes, follow-calls/deep/comments-only, and universal --in path filtering. I don't have the tarball yet. The code-exam-phase9d-novocab.tar isn't in uploads. Please upload it so I can unpack it and have the actual current codebase to work against. On your 8-item roadmap — makes sense as a sequencing. Task 1 (archive support in --build-index) is a clean standalone feature that extends the input pipeline without touching search/browse/metrics. A few initial design thoughts before I see the code: Task 1 — Archive support: The ! delimiter for in-archive paths is sensible (similar to Java's jar:file:///path/to/jar!/entry/path convention). Key questions to discuss: Nested zips (zip-in-zip) — do we cap recursion depth, or unbounded? I'd suggest a reasonable cap (say 5 levels) with a warning. For .7z, Node.js has no built-in support and no good zero-dep library. We may need a small dependency or shell out to 7z command if available. .zip, .tar, .tar.gz are all doable with Node built-ins or zero-dep code. How important is .7z for the first iteration? Should the archive itself be treated as a "directory" in the index, so /path/to/archive.zip!src/main.java shows up naturally in file-tree, hot-folders, etc.? Task 2 — Binstrings: I've read binstrings_2.py. The .op pseudo-source format is clever — it looks like regular C to the parser, so the existing regex function extractor handles it for free. The main work is integrating the binary→strings→.op pipeline into the --build-index path so it happens automatically when encountering .exe/.dll/.so/etc. Go ahead and upload the tarball and we can dive into task 1 specifics. code-exam-phase9d-novocab.tar tar Above all sounds right, though I'm not sure about "zero npm dependencies". For loading local LLM models in GGUF files, node-llama-cpp is used, so npm install node-llama-cpp , I think. Definitely some cap on zip recursion. Shame about 7z not built-in, and we can skip in initial implementation, but will be necessary soon-ish. For now, yes, paths shown in cmd output should include full path with the zip's path/filename. Probably will look too cluttered, and made into an option, but for now, definitely. I'm attaching the tar file. 1:17 PM Architected archive extraction strategy with recursion limits and path formatting Architected archive extraction strategy with recursion limits and path formatting 284/284 — clean baseline confirmed. Good. You're right about node-llama-cpp — that's an optional runtime dependency for the local LLM path. The "zero dependencies" refers to the core search/analysis being dependency-free (nothing in package.json dependencies). Now, having read through the codebase, here's my design proposal for Task 1 — Archive support in --build-index. Let's discuss before I start coding. Where it hooks in: The buildIndex() method at line 758 of CodeSearchIndex.js. Currently the flow is: resolve file paths → filter out BINARY_EXTENSIONS → read each file → SHA1 dedup → save indexes. Archive support inserts a new phase between resolving paths and reading files: "expand archives into virtual entries." Path format: relative/path/to/archive.zip!src/main/App.java. For nested archives: outer.zip!libs/inner.jar!com/example/Foo.java. The ! delimiter works well — it's the same convention Java uses for JAR URLs. What Node.js can handle zero-dep: ZIP (including .jar, .war, .ear, .apk): I'll write a zero-dep ZIP reader. ZIP format is straightforward — read the central directory from the end of the file, then seek to each local file header and inflate with built-in zlib.inflateRawSync(). This handles the majority of real-world archives. TAR (.tar): Sequential 512-byte headers, easy to parse. GZIP (.gz, .tgz, .tar.gz): Built-in zlib.gunzipSync(), then treat as tar or source file. Standalone .gz files: gunzip → if the inner filename has a source extension, index it. Skip for now (need external tools or native deps): .7z, .rar, .bz2, .xz, .zst — can add later by shelling out to 7z command if available on the system Recursion: Zip-in-zip handled recursively with a depth cap of 5. When a zip entry is itself an archive, process it the same way with the path prefix accumulated. Warning printed when depth cap hit. Changes to BINARY_EXTENSIONS: Archives move out of BINARY_EXTENSIONS into a new ARCHIVE_EXTENSIONS set. The buildIndex filter step checks both — archives get expanded instead of skipped, true binaries still skipped (until Task 2 adds binstrings). New file: src/archive.js (~300-400 lines probably) — ZipReader, TarReader, expandArchive(filePath, depth) → yields {virtualPath, content} entries. Key design question for you: When building the index, should the archive file itself appear as an entry too (with metadata like "this is a zip containing N files"), or only its contents? I'm leaning toward contents-only, since the archive is just a container. Does this design sound right? Anything you'd change before I start? Sounds like a good plan. I think no, don't have the zip itself appear in the index. The tool does do searches in paths and filenames, as well as in file contents, BUT that should pick up index name, assuming there's some important content in the zip's path/filename (hypothetically, "/SUPER-SPECIAL/CodeThatImplementsSmokingGunFeature.zip"). One question: will the zip etc. be unzipped into memory, contents indexed, and no external file created? That I think is the right way to do it. The index has no need for external files. I can see problems with small-compressed portions that expand into something massive, but that's not going to be helped by first storing the massive part on disk. Of course, there might be "zip bombs" (20 GB file of zeroes) but nothing to do about that. Some zips will be password encrypted. Nothing you can do but put up a big message so the user sees that its contents will be missing from index. I think that's it, you should go ahead with task 1. There may be some small aspect of Task 2 you need to account for here, but otherwise just stick with task 1. Show more 1:29 PM Architected in-memory archive expansion with recursive depth limits and encryption warnings Architected in-memory archive expansion with recursive depth limits and encryption warnings Good — all in memory, no temp files. Password-protected zip detection with loud warning. And I'll leave a clean hook point for Task 2's binstrings integration. Let me build it. Charted implementation strategy for archive extraction and indexing Charted implementation strategy for archive extraction and indexing Now I have the full picture. Let me build this step by step. Charted modifications to integrate archive expansion into indexing workflow Charted modifications to integrate archive expansion into indexing workflow Now update utils.js to split archives and executables out of BINARY_EXTENSIONS: Examined CodeSearchIndex.js modifications for archive integration strategy Examined CodeSearchIndex.js modifications for archive integration strategy Now integrate archive expansion into CodeSearchIndex.js. First, update the imports: Architected archive extraction strategy for in-memory indexing Architected archive extraction strategy for in-memory indexing Now modify the buildIndex method. The key changes are in the file filtering and processing loop: Identified need to refactor directory traversal for archive file detection Identified need to refactor directory traversal for archive file detection Now I need to update _walkDir to also collect archive files during directory scans: Reconciled file categorization logic with statistics tracking requirements Reconciled file categorization logic with statistics tracking requirements Now update the stats section to properly reflect archive-sourced files: Investigated whether additional methods required identical archive handling Investigated whether additional methods required identical archive handling Let me check if there are other walk methods that might also need updating: Verified backward compatibility and prepared to execute testing phase Verified backward compatibility and prepared to execute testing phase Good. Now let me run existing tests to confirm nothing's broken: Verified test suite integrity before commencing archive implementation work Verified test suite integrity before commencing archive implementation work 284/284 still passing. Now create the archive-specific tests: Verified archive tests and prepared comprehensive validation Verified archive tests and prepared comprehensive validation 22/22 archive tests pass. Now verify all existing tests still pass: Verified test suite completion and investigated additional code sections Verified test suite completion and investigated additional code sections 306/306 — all clean. Let me also check if there's a second walk method used for vocabulary that should also pick up archives: Reconciled archive indexing strategy with user requirements Reconciled archive indexing strategy with user requirements That's scanExtensions — just a diagnostic tool that counts extensions. Doesn't need archive support. Everything looks good. Let me package this up: Synthesized indexing strategy for compressed archives Synthesized indexing strategy for compressed archives Task 1 complete. 306/306 tests pass (284 existing + 22 new). What shipped: New file: src/archive.js (758 lines) Zero-dep ZIP reader — parses central directory, handles stored (method 0) and deflated (method 8) entries, detects encrypted entries with loud warning Zero-dep TAR reader — POSIX ustar and GNU formats, base-256 size encoding for large files GZIP handler — auto-detects whether inner content is a tar or a standalone file Recursive expansion — zip-in-zip, jar-in-zip, tar.gz-in-zip, depth cap of 5 with warning ZIP bomb protection — 256MB per-entry decompressed size limit ! delimiter path convention: archive.zip!src/main/App.java, nested: outer.zip!libs/inner.jar!com/example/Foo.java Modified: src/utils.js BINARY_EXTENSIONS split into ARCHIVE_EXTENSIONS, EXECUTABLE_EXTENSIONS, MEDIA_BINARY_EXTENSIONS (union still exported as BINARY_EXTENSIONS for backward compat) Modified: src/core/CodeSearchIndex.js buildIndex() — two-phase: index regular source files first, then expand and index archives. Archives expanded entirely in-memory, no temp files. _walkDir() — now also collects supported archive files from directory scans Categorized skip reporting: media files, executables (with "use --binstrings in future" hint), unsupported archives (.7z/.rar) SHA1 dedup works across disk files and archive contents Task 2 hook point: EXECUTABLE_EXTENSIONS tracked separately. In archive.js, when a binary is found inside an archive, it hits stats.skippedBinary++ — that's where binstrings processing will plug in. Not yet supported (as discussed): .7z, .rar, .bz2, .xz — reported as "unsupported archives" during build. Will need shelling out to 7z command.

The recursive zip testing is worth doing. If you want a quick way to create test zips on Windows, you could even use the tool on itself — zip up a directory that contains zips. The depth-5 cap and the warning message should be easy to verify that way. One thing I noticed in your output: --use-tree-sitter is specified but tree-sitter isn't wired up yet in the Node.js version (that's your Task 4). It's silently falling back to regex parsing, which is why it still found 307 functions fine. Just flagging so it doesn't surprise you later. Ready for Task 2 (binstrings integration) whenever you are, or happy to wait if you want to do more archive testing first. The hook point is already in place in archive.js — where it currently does stats.skippedBinary++ for executables found inside archives is exactly where the binstrings processing will plug in. You got interrupted with "Claude's response could not be fully generated". Last I see in your chain of thought is: "Now add the --demangler CLI arg. Let me find where to add it:" with some further thoughts/work underneath that. Can you pick up from there? 2:14 PM Excavated prior context to resume CLI argument implementation Excavated prior context to resume CLI argument implementation Let me pull up where I left off from the transcript.

Show more 2:29 PM Retrieved file size data from earlier conversation search results Retrieved file size data from earlier conversation search results That's a good question, and I can actually trace the exact path. Earlier in this turn, when I was trying to find the interrupted binstrings work, I ran conversation_search with query "binstrings Node.js archive expandArchive demangler". One of the results returned was from the "Converting Python exam code to Node.js" chat, and it included this snippet from you: H: FYI: Directory of C:\work\code_exam\.nodejs_src 02/17/2026 03:03 PM 1,614,857 function_index.json 02/17/2026 03:03 PM 393,375,631 inverted_index.json 02/17/2026 03:03 PM 743,465,731 literal_index.json That search result came back as context while I was looking for something else entirely (the demangler code). But once it was in my context window, it was available when I needed it. So when I fixed the literal index crash and then thought "what else uses JSON.stringify for large data?", I already had the concrete number sitting right there — 393MB for the inverted index, well within the danger zone. It's basically the same thing that happens when you're grep'ing through code looking for one thing and you notice a bug on a nearby line.

The OOM is during buildInvertedIndex() — it's trying to hold ~700MB of this.files content + ~500MB of this.fileLines + the growing inverted index Map all at once, blowing past 4GB heap. The fix: free this.files before building the inverted index — it's not needed again during the build phase (inverted and function indexes both work from this.fileLines). Investigated function dependencies and index construction methods Investigated function dependencies and index construction methods Now let me verify what buildFunctionIndex actually reads from: Identified memory optimization strategy by clearing file content Identified memory optimization strategy by clearing file content Good — both buildInvertedIndex and buildFunctionIndex only need this.fileLines, not this.files. The this.files Map (holding ~700MB of raw content) is dead weight during those phases. Also, the buildInvertedIndex method itself builds a huge lineToFiles Map that should be freed after writing. Identified memory bloat from intermediate objects during indexing Identified memory bloat from intermediate objects during indexing I see multiple problems: this.files (~700MB) still alive during inverted index build lineToFiles Map (huge) AND inverted object (copy of same data) both alive simultaneously this.invertedIndex = inverted keeps yet another copy in memory Let me fix all three: Refactored guards and streamlined index building logic Refactored guards and streamlined index building logic Now fix buildInvertedIndex — stream directly from lineToFiles to disk without building the intermediate inverted object: Identified memory leak in buildFunctionIndex guard logic Identified memory leak in buildFunctionIndex guard logic Now fix the buildFunctionIndex guard: Investigated memory allocation issue in code examination process Investigated memory allocation issue in code examination process Check if there's another guard at line ~1207: Verified search code logic and examined memory usage patterns Verified search code logic and examined memory usage patterns That's the search method — only called after loading, not during build. Fine.

Package it: Analyzed memory optimization strategies for indexing operations Analyzed memory optimization strategies for indexing operations Three memory fixes in this build: _saveLiteralIndex — streaming write (entry-by-entry via fs.writeSync), no JSON.stringify of the whole index. This fixed the 822MB literal index save. buildInvertedIndex — eliminated the intermediate inverted object entirely. Now streams directly from the lineToFiles Map to disk. Also set this.invertedIndex = null during build (reloaded from disk after). this.files lifecycle — freed after saving literal index, before building inverted index. This drops ~700MB during the memory-peak phase. Reconstructed from this.fileLines after all build phases complete. Peak memory during build is now ~1.5GB (fileLines + lineToFiles Map), down from ~3.5GB+ (files + fileLines + lineToFiles + inverted + invertedIndex all co-existing).

Show more 3:20 PM Synthesized debugging findings and concluded productive session Synthesized debugging findings and concluded productive session Good stopping point. Solid day's work — two major features landed and a critical OOM fix. Where we stand: Task Status 1. Archive support ✅ Complete, tested on real Python 3.10 install 2. Binstrings ✅ Complete, demangling works (partially — older vc++filt misses some newer mangling) 3. Multiple indexes Next up 4. Tree-sitter Queued 5-8 Queued Known issues to revisit: Some mangled names not demangled — your vc++filt.exe is from 2011, newer MSVC mangling has evolved. Could support --demangler accepting multiple paths (try each in order), or try undname.exe from MSVC toolchain as a second demangler. The /fast :: --in dll returning no results is interesting — the :: is probably getting normalized away by the inverted index (it strips/collapses whitespace and short tokens). Worth investigating but not urgent. Metrics for the day: 335 tests passing 20,175 lines across 18 source + 12 test files Streaming save/load handles 1.4GB of index files 25,733 files / 9.4M lines / 362K functions indexed from a real Python install Enjoy the evening. I'll be here when you're ready for Task 3. Yes, this alone was good progress. And earlier today in the previous chat, Claude took care of several other things: -- using codebase's vocabulary (from --discover-vocabulary) to guide extraction of terms from patent claim text -- testing extraction of terms with local LLM, Qwen Coder, and use of --vocab-tight for local LLMs. -- new --follows-calls and --deep commands to have --extract show not only named function, but also its callees. -- new --extract-comments command that only shows full-line comments from a function; works with --follows-calls to generate nice trees of major source-code comments; followed by a caveat that says "Tip: Comments can lie! Verify against actual code logic." 3:25 PM Acknowledged progress recap spanning multiple development sessions Acknowledged progress recap spanning multiple development sessions That's a packed day. Four distinct feature areas: Earlier session (previous chat): Vocabulary-guided patent claim term extraction Local LLM (Qwen Coder) testing with --vocab-tight --follows-calls / --deep for recursive function extraction --extract-comments with call tree traversal (and the honest caveat) This session: Archive expansion in --build-index (ZIP/TAR/GZ, nested, encrypted detection) Binstrings for executables (extract, filter, demangle, .op generation) Streaming JSON save/load to handle 1.4GB indexes without OOM The --extract-comments with --follows-calls producing comment trees is a particularly nice combination for code review — gives you a quick architectural overview of what the developers intended at each level of a call chain, without wading through implementation. The "comments can lie" caveat is earned wisdom. Between the patent claim analysis, binary string extraction, and archive traversal, this tool covers a pretty unusual range — from legal document analysis down to raw executable forensics, all through the same search interface. Have a good night. Looking at the next tasks in the list at the top of this chat, I wonder if the next one, #3 (loading multiple indexes), is perhaps more complicated with less immediate benefit, than #4 (tree-sitter), #5 (multisect look in classes as as well as functions/files/folders), and #7 (possibly naive handling of callee method names when same name in multiple classes). Have you any thoughts or preferences? 5:55 PM Weighed architectural complexity against immediate value gains Weighed architectural complexity against immediate value gains I think your instinct is right. Task 3 (multiple indexes) is an architectural change that ripples through every command — you need to decide how results merge, how paths disambiguate across indexes, how interactive mode switches context. High effort, and the payoff is mostly convenience until you actually need cross-index comparison. My preference order for the other three: Task 7 first (callee ambiguity). This has the highest urgency because it directly affects --follows-calls and --deep which just shipped today. If --callees thinks run() in ClassA and run() in ClassB are the same target, then --follows-calls is silently following wrong call chains. The fix also improves --callers, --call-chain, and --file-map — broad impact from a relatively contained change. The function index already stores Class::method qualified names; the issue is that the call-site scanner matches bare names without checking which class context the call is in. Task 5 next (multisect class scope). Small, contained change to an already-working feature. The multisect narrowing logic is in one place, and adding a class scope between function and file is straightforward — you already have class membership from the function index. Quick win. Task 4 last (tree-sitter). High value but also highest complexity — it's an optional dependency in an air-gapped tool, so you need to think about distribution (bundle the WASM grammars? require pre-install?). And the regex parser is working well enough that the other improvements don't depend on it. Want to start on Task 7? Yes, start Task 7. I don't remember if there are any specific examples of it doing the wrong thing, but it feels likely that it's sometimes wrong, and yes, with potentially terrible results for some of the new commands. On tree-sitter in air-gapped tool, this was addressed in the py code, I think, where all tree-sitter-XXX dependencies were resolved at load time. In the air-gapped tool, there will be a period when the tool is installed and internet is still available. There cannot be any features after then which demand new downloads/installs, but on any given computer there will be a period when the administrator can do npm installs. Of course, during run time, the tool could for the first time encounter a brand-new file extension, requiring tree-sitter-newfangledlanguage, but since the computer is air-gapped those .newfangled files aren't going to magically show up, they'll be on the machine at install-time. Anyhow, Task 7, then 5, then 4, then we'll see about 3. I have some notes on combined indexes to share when we work on that. Writing the notes persuaded me this was difficult. On Task 7, of course construct some contrived tests that exercise disambiguation of overloaded method calls, etc. Show more 6:03 PM Examined Node.js codebase to understand callers and callees handling Examined Node.js codebase to understand callers and callees handling Let me first understand how callers/callees currently work and where the ambiguity creeps in.

The core problem: findCallees and related methods look up bare names in _getKnownFunctions(), which maps "run" → [ClassA::run, ClassB::run, ...]. Then they grab defs[0] blindly, and dedup by bare name so only one "run" ever appears even if different classes' methods are called.

Are all callee lookups gated through one place? No. There are three distinct code paths: findCallees() — fixed ✅. Used by --callees, --follow-calls, --call-tree, --call-chain (graph.js), file tree deps. getAllFileDeps() — NOT fixed. Has its own bestTarget() that only does directory proximity. Used by --file-map. However, it already filters out self/this calls and same-file local functions, so the most egregious wrong-class errors are avoided. Its residual ambiguity is "which of several cross-file definitions of setup() is this bare call targeting?" — for file-level deps, directory proximity is actually a decent heuristic. getCallCounts() / --most-called / --hotspots — counts raw call occurrences by bare name. Doesn't resolve targets at all, just counts. Disambiguation isn't really applicable here since it's answering "how often is foo called anywhere" not "which foo." So the file-map could be improved but it's lower priority since its existing filters already handle the worst cases. 2. Import aliasing (import X from Y as Z, then Z.foo())? No. The regex-based approach has no concept of imports, variable types, or aliases. When it sees Z.foo(), it checks whether Z matches a known class name from the function index. If Z is an alias for class Widget, it won't make the connection. This is fundamentally a type-inference problem that regex can't solve. Tree-sitter (Task 4) gets us part of the way — it can parse import statements reliably — but full alias resolution would require building a symbol table, which is approaching what a language server does. Not impossible for a small set of languages but a significant project. 3. Inheritance (class Derived : public Base, then this->foo() where foo is in Base)? No. If Derived::tick() calls this->foo(), my resolver looks for Derived::foo first (same-class, step 3). If that doesn't exist because foo is only defined in Base, it falls through to same-file → directory proximity → arbitrary pick. If Base is in the same file it'll likely work by accident. If Base is in a different file, it's a coin flip. Fixing this properly requires parsing class declarations to extract inheritance relationships (class Derived : public Base in C++, class Child(Parent) in Python, class Sub extends Super in JS/Java). That's actually regex-feasible — the patterns are distinctive. Build a parent map, then when same-class lookup fails, walk up the inheritance chain. It's a bounded enhancement, maybe 50-80 lines, and would meaningfully improve C++ and Python results. Want me to add it now, or queue it? Very useful, honest answers. I think maybe you had better put in your fix to scenario 3 first, then I'll test. Before you give me the new tarball with fix for scenario 3, can you please quickly scan all commands to see if there are any more out there, like --file-map, that might also have their own DIY quick-and-dirty lookup? I hear you that for --file-map what it does now is actually probably correct, similar for --most-called and --hotspots, but please consider if there are others that I haven't mentioned, that at least might be similarly implicated (even if we then conclude, okay, it's like your "how often is foo called anywhere" not "which foo"). When you give me the new tarball, also give me a short list of scenarios that you think would have been wrong before, and that are correct now. 6:26 PM Audited code paths and architected comprehensive inheritance resolution system Audited code paths and architected comprehensive inheritance resolution system Let me do the full audit first, then add inheritance.

Display catalog, not resolution No other hidden DIY resolvers. Now let me add inheritance: Architected inheritance mapping system across multiple programming languages Architected inheritance mapping system across multiple programming languages Good — now I see exactly what's needed. The class patterns in the regex parser capture class names but don't capture parent classes. I need to add inheritance parsing.

Now: Dog.speak. this->update() in Player::tick → was picking first update def alphabetically. Now: Player::update, not Enemy::update. Encoder.process() AND Decoder.process() both called by Pipeline.run → was deduped to one "process" entry. Now: both appear separately. self.breathe() in Dog.live where Dog doesn't define breathe, inherits from Animal → was ambiguous coin flip between Animal.breathe and Machine.breathe. Now: walks Dog→Animal chain, picks Animal.breathe. this->render() in Button::onClick where Button inherits Widget → was directory-proximity guess. Now: walks Button→Widget chain, picks Widget::render. self.core_method() in Leaf.leaf_action, multi-level Leaf→Middle→Base → was ambiguous. Now: walks two levels up, finds Base.core_method. self.render() in Child.display where Child overrides Base.render → correctly still picks Child.render (same-class match fires before inheritance walk). --follow-calls recursive extraction was following wrong class's method into wrong source. Now: passes resolved filepath as file hint for deeper recursion. Code exam phase9g disambig TAR I am trying to run node test_disambiguation.js . I have to admit that until now I have not tried to run any of the test scripts. I was happily using them in the py version, but hadn't yet tried with js. When I ran node test_disambiguation.js, I see a bunch of test successes in green, but also a lot in red that make me suspect I am doing something wrong with the test, or running it from the wrong place? C:\work\code_exam\Nodejs_port\code-exam\test>node test_disambiguation.js 6:42 PM Identified incorrect test execution method; flagged missing flag requirement Identified incorrect test execution method; flagged missing flag requirement You need the --test flag. From the code-exam directory (not from inside test/): cmd cd C:\work\code_exam\Nodejs_port\code-exam node --test test\test_disambiguation.js Without --test, Node runs the file as a regular script — it imports the node:test module but doesn't wire up the test runner, so the describe/it blocks execute but reporting is garbled. When I do it that way, everything is nice and green. Now I just need to understand 1 or 2 of the tests themselves. Like for the following: ▶ Disambiguation: Multiple overloaded targets both called ✔ Pipeline.run should show both Encoder.process and Decoder.process (137.8891ms) ✔ Disambiguation: Multiple overloaded targets both called (254.406ms) I see the corresponding place in test_disambiguation.js . Clever. But the test is of the logic, in the context of JS itself, yes? How can we extrapolate from this working as expected, with inline JS classes, to the tool analyzing e.g. C++ code doing the same correct thing? Here in this test you've got actual Encoder and Decoder classes, each with an actual process() function. The test actually runs them. The tool itself is not going to be running the target code, which at any rate might be in C++ or Java or whatever. What am I not understanding? Show more 6:51 PM Clarified that tests perform static analysis, not code execution Clarified that tests perform static analysis, not code execution You're misreading what the test does — and it's a reasonable misread because the source in the test looks like it could be executed. But it never is. Look at the test closely: js fs.writeFileSync(path.join(SRC_DIR, 'dual.py'), ` class Encoder: def process(self, data): return data.encode() ... `); That writes a Python file to disk. It's just a string. Node doesn't execute it. Then: js runCLI(`--build-index ${SRC_DIR} --index-path ${IDX_DIR} --skip-semantic 2>&1`); That runs node src/index.js --build-index ... as a subprocess — the tool indexes that .py file using regex parsing, same as it would for any file you point it at. Then: js const out = runCLI(`--callees "Pipeline::run" --index-path ${IDX_DIR} 2>&1`); assert.ok(hasEncoder && hasDecoder, ...); That runs --callees and checks the CLI text output for the strings "Encoder" and "Decoder". The tool never runs the Python code. It's doing static analysis — regex pattern matching on the text content of dual.py. The same logic applies regardless of whether the file is .py, .cpp, .java, or .rs. The regex function parser picks up class Encoder: and def process(self, data): as class and method definitions, then the disambiguation resolver figures out which process is being called on which line. The C++ tests in the same file (like hierarchy.cpp with Widget/Button) work identically — write a .cpp file to disk, index it, check CLI output. The C++ is never compiled or executed. It's just text that the regex parser recognizes as C++ class/function patterns. Oh for heaven's sake, I completely missed the ` and ' around the code. fs.writeFileSync(path.join(SRC_DIR, 'dual.py'), STUFF ); Ok, got it. I didn't even notice it was Python not JS you were "running". Doh. So I could easily construct tests like these ones. But you have already. Okay, I trust that you've addressed Task 7, subtracting the several points you made earlier. Those will need to be addressed (TODO), but good for now. Go ahead and do Task 5 next (multisect class scope). I assume this will often be the same as file scope, but parts of a class might be in .h, parts in .cpp? Or single class spread over multiple .cpp or multiple .java, etc.? 6:58 PM Examined multisect class-level scope implementation across languages Examined multisect class-level scope implementation across languages Right — that's the key design question. In Python/Java/JS, a class is almost always in one file. In C++, Widget might have its declaration in widget.h and method bodies in widget.cpp (or even split across widget_render.cpp and widget_input.cpp). The function index already tracks Widget::render regardless of which file it's in, so we have the data to group by class across files. Let me look at how multisect works currently. Architected class-level scope insertion between function and file hierarchies Architected class-level scope insertion between function and file hierarchies Now I have the full picture. Current multisect has three scopes: function → file → folder. I need to insert class between function and file. The function index already stores qualified names like Widget::render, so I can group functions by class. For C++ split across .h/.cpp, Widget::render in widget.cpp and Widget::onClick in widget_input.cpp both have class name Widget. Incorporated class_matches into the return value Incorporated class_matches into the return value Now add class_matches to the return value: Investigated display functionality for class-scoped matching results Investigated display functionality for class-scoped matching results Now update the display. Let me find the multisect output formatter: Recognized duplicate message and resumed Task 5 implementation Recognized duplicate message and resumed Task 5 implementation I think that's a duplicate of your earlier message — I'd already started on Task 5. I was mid-way through adding the class display section to multisect.js. Let me pick up where I left off. Orchestrated implementation roadmap for class-level search functionality Orchestrated implementation roadmap for class-level search functionality Good — the engine side is done. Now I need to add the display section. Let me see where to insert it between function and file display: Verified function compatibility with class match structures Verified function compatibility with class match structures Now check that matchIdfScore works with class matches (it needs matched_indices): Verified implementation details and mapped class scope strategy Verified implementation details and mapped class scope strategy Good — uses matched_indices which class matches have. Now check if the claim analyzer also needs updating: Verified existing functionality before proceeding with multisect class scope implementation Verified existing functionality before proceeding with multisect class scope implementation The claim analyzer picks individual functions — doesn't need class-level for its workflow. Let me run tests: Prepared to commence class-level multisect scope testing implementation Prepared to commence class-level multisect scope testing implementation All passing. Now write the class scope tests: Diagnosed output discrepancies and prepared for subsequent task Diagnosed output discrepancies and prepared for subsequent task Let me see what's actually being output: Identified test data flaws and diagnosed scope matching issues Identified test data flaws and diagnosed scope matching issues The first test has a red herring — the comment # transmit the encrypted compressed data in send() contains all three terms as substrings. So function-level matches [3/3], class match gets suppressed. But the other failures suggest the class scope isn't triggering at all. Let me check the C++ case: Verified function indexing and contemplated cross-file class scope matching Verified function indexing and contemplated cross-file class scope matching Good — functions are indexed as Renderer::initialize, etc. Now check multisect: Architected solution to expand class matching beyond file boundaries Architected solution to expand class matching beyond file boundaries The problem: Phase 2 only scans "survivor files" (files containing ALL terms). For class scope, terms are spread across files — no single file survives. I need to expand the Phase 2 scan to include files belonging to class candidates. Identified need to revise Phase 2 completion message reference Identified need to revise Phase 2 completion message reference Also fix the Phase 2 completion message and ensure file-level matches still only use original fileSurvivors: Restructured test data to isolate separated terms across methods Restructured test data to isolate separated terms across methods Now fix the test data — the Python test had all terms in one comment. Let me also verify the C++ split works: Identified separator inconsistency between Python dots and JavaScript colons in function indexing Identified separator inconsistency between Python dots and JavaScript colons in function indexing The functions use . for Python (SecureChannel.encrypt_data) not ::. My class grouping only looks for ::. Need to handle both: Identified class name extraction issue requiring correction Identified class name extraction issue requiring correction Now fix the post-Phase 2 class match builder too: Investigated dedup function logic for class scope matching Investigated dedup function logic for class scope matching Also fix the dedup in multisect.js display which only checks ::: Identified and resolved qualified name bug in function boundaries lookup Identified and resolved qualified name bug in function boundaries lookup Found it. _getFuncBoundaries returns base_name (bare), not the full qualified name. So funcMap entries have encrypt_data not SecureChannel.encrypt_data, and the class extractor finds nothing to split on. Verified class-level matching, noted formatting conventions, prepared to implement multisection class scope Verified class-level matching, noted formatting conventions, prepared to implement multisection class scope Now remove the debug logging: Verified test completion and prepared for next task Verified test completion and prepared for next task All 356 existing tests pass. Now the class scope tests: Validated class scope testing implementation successfully Validated class scope testing implementation successfully 11/11 class scope. Full suite: Prepared tarball packaging completion Prepared tarball packaging completion 367/367. Package: Prepared to deliver Task 7 results and commence Task 5 analysis Prepared to deliver Task 7 results and commence Task 5 analysis 367/367 tests (21 disambiguation + 11 class scope new). 21,880 total lines. This tarball includes both Task 7 (disambiguation + inheritance) and Task 5 (class scope). Task 5 summary — what changed: The core issue was that _getFuncBoundaries() returned base_name (bare, e.g. encrypt_data) instead of the qualified name (SecureChannel.encrypt_data). That meant funcMap entries had no class context, so the class grouper found nothing to group. Changing it to return the full qualified name was the key fix — it also improves the file-level display (now shows in SecureChannel.encrypt_data instead of just in encrypt_data). Three places needed . handling in addition to ::: Phase 1b class candidate computation, the post-Phase 2 classMap builder, and the display dedup/method-name extraction. The bigger architectural fix was Phase 1b — after identifying file-level survivors, scanning the function index to find classes whose combined term coverage across files meets minTerms, then adding those files to the Phase 2 scan. Without this, the C++ split-file case would never work (no single .cpp file has all terms). Scenarios that were wrong before, correct now (Task 5): Python class, terms across methods — cipher in encrypt_data(), deflate in compress_data(), transmit in send(). No single function has all 3, no CLASS-level match appeared. Now: SecureChannel matches at class level. C++ class split across .h/.cpp — Renderer::initialize in renderer_init.cpp (viewport), Renderer::rasterize in renderer_draw.cpp (triangle), Renderer::composite in renderer_composite.cpp (alpha). No file has all 3. Now: Renderer matches at class level across 3 files. Dedup — when a single function already contains all terms, the class match is suppressed (redundant). With --verbose, both show. Java/JS classes — HttpClient with methods authenticate/download/retry; EventBus with subscribe/publish/unsubscribe — all now produce class-level matches. Selective matching — UserModel matches email;password but not ProductModel; ProductModel matches price;inventory but not UserModel. Code exam phase9h classscope TAR I was surprised to see class-level multisect results, immediately, without even trying: .spinellis code-exam> /multisect "open;close;read;write;tell" Phase 1: 247 survivor files (from 11349 candidates) in 0.9s Phase 1b: 124 additional files from class candidates Phase 2: details for 371 files in 0.1s ... === CLASS-level matches (17 classes (1 suppressed - covered by function matches)) === [1] ACE (ace\ace\ace.cpp, 35 methods, 1787 lines) [5/5] IDF:9.0 [3] L47 out_of_handles() // Without threads check for EOPNOTSUPP [4] L131 select() ACE_Handle_Set *writefds, [1] L235 process_active() ::OpenProcess (PROCESS_QUERY_INFORMATION, FALSE, pid); [2] L248 process_active() ::CloseHandle (process_handle); [5] L2711 handle_timed_complete() // any platform where we can't tell just from select() (e.g. AIX), Oh, wrong kind of "tell" (I meant ftell) but still, this is quite good. So this first one, it would have been shown before as file-level, but since it's all in a class, it's now shown at class-level, and will be suppressed in file-level? Okay, here's one that spans multiple files: [6] Consumer_Handler (4 files, 8 methods, 307 lines) [5/5] IDF:9.0 [1] L13 open() (..._Server\Consumer_Router.cpp) Consumer_Handler::open (void *a) [3] L20 Consumer_Handler() (..._Server\Consumer_Router.cpp) Consumer_Handler::Consumer_Handler (ACE_Thread_Manager *tm) [2] L76 nonblk_put() (...ete_Connection_Handlers.cpp) // not when flow control occurs).

Doesn't bother me at all, just wonder why. === FILE-level matches (219 files (28 suppressed - covered by function matches)) === Should that say "covered by function or class matches"? Well, it's awesome you pulled this together so nicely and so quickly. Show more 7:21 PM Reconciled class-level suppression logic and term ordering across files Reconciled class-level suppression logic and term ordering across files Good eye on all three points. 1. Yes — ACE would have shown as file-level before. Now it's class-level, and the file-level entry for ace.cpp gets suppressed (unless --verbose). 2. Term order — the display sorts by line number, not term index. For a multi-file class, L13, L20, L76, L100, L102 are in ascending line-number order, but they happen to come from terms [1], [3], [2], [5], [4]. It's showing you where the matches are in the code, not listing terms in definition order. 3. The suppression message — you're right, that's a bug. File-level only checks fileCoveredByFunction(), not class coverage. Let me fix that quickly, and also fix the message. Marshaled thoughts to address user's technical inquiries comprehensively Marshaled thoughts to address user's technical inquiries comprehensively Updated tarball — 367/367 still passing. The fix: file suppression now checks both function-level and class-level coverage. A file like ace.cpp that's fully covered by the ACE class match will now be suppressed too, and the message reads "covered by function or class matches." On the Consumer_Handler multi-file result — that's exactly the scenario that motivated the Phase 1b expansion. No single file contains all 5 terms, but the class's methods across 4 files collectively do. Before Task 5, that would have shown as 4 separate file-level partial matches (each [2/5] or [3/5]), which is much harder to interpret than one Consumer_Handler [5/5] class-level result. Code exam phase9h classscope TAR That all makes sense. Done with Task 5. Next up would Task 3 (load multiple indexes), 4 (tree-sitter), or 6 (symtab for all callees, especially to flag which ones are not in index). You indicated 3 and 4 both complicated. My earlier notes on 6 said: Provide a command that shows all call targets, and indicates which are, or are not, inside the codetree. This is the opposite of the current --entry-points and --gaps commands. There will be issues with same-named call targets not being the same, because in different class etc. contexts. So that might be a natural follow-on to the nice Task 7 you did, handling a lot (albeit not all) known class::method ambiguities. What think, 3, 4, or 7? 7:40 PM Weighed three options and advocated for Task 6 as natural progression Weighed three options and advocated for Task 6 as natural progression Task 6 is the natural next move. Here's why: Task 6 builds directly on what's fresh. The disambiguation resolver, the known-functions cache, the inheritance map — all just written and debugged. Task 6 is essentially: scan a function's call sites, check each against _getKnownFunctions(), and partition into "resolved in index" vs "external/unknown." The resolver already does 90% of this work; we just need to report the other side of the ledger. It's also the most immediately useful of the three. When you're examining unfamiliar code, knowing "this function calls 12 things, 8 are in the index and 4 are external (libc, OS API, third-party)" is a huge orientation signal. And for the patent claim analysis workflow — if a claim says "encrypting the data" and multisect finds SecureChannel.encrypt_data, seeing that it calls aes_cipher() which is not in the index tells you the actual crypto is delegated to an external library, which matters for claim mapping. Task 3 (multiple indexes) is still the hardest — every command needs result merging, path disambiguation, context switching. Better to have more features solid on single indexes first. Task 4 (tree-sitter) is high value but won't change what we can do, just improve accuracy of what we already do. The regex parser is working well enough that Tasks 6 benefits from it as-is. Want me to start Task 6? I'm thinking a --call-inventory or --call-map command on a function that shows something like: NetworkManager::connect (net/manager.cpp, 45 lines) calls 12 functions: IN INDEX (8): Socket::open net/socket.cpp (23 lines) [method_dot] Socket::write net/socket.cpp (18 lines) [method_dot] DNSResolver::lookup net/dns.cpp (67 lines) [qualified] ... EXTERNAL (4): malloc() [direct] — not in index memcpy() [direct] — not in index SSL_CTX_new() [direct] — not in index (likely OpenSSL) pthread_create() [direct] — not in index (likely pthreads) And a bulk version (--call-inventory --all or a path filter) that summarizes across many functions/files: "347 unique call targets, 289 in index, 58 external" with the external ones listed. Yes, Task 6 is perfect next step, and your --call-inventory FUNCTION, and especially --call-inventory --all, if that can cleanly generate a bill-of-missing-materials list (NOT IN INDEX) for the entire codetree. If you can actually label that part as you did in the sample above with (likely OpenSSL) etc., that's an even bigger win. If you can do that, might as well mark the more obvious C/C++ run-time-library (RTL), WinAPI? Or no, if you did some but not others maybe worse than not describing likely provenance at all, and being thorough would require big lists. I leave that up to you for now. What [method_dot], [qualified] ? 7:47 PM Clarified syntax notation and architected library-labeling heuristic Clarified syntax notation and architected library-labeling heuristic [method_dot], [qualified], [direct] are the existing call_type tags from findCallees — they tell you how the call appeared syntactically: obj.method() vs Class::method() vs bare func(). Useful for disambiguation confidence but probably noise in this output. I'll drop them from --call-inventory display — the point here is the in/out partition, not syntax. On provenance labels: I'll do a lightweight prefix-matching heuristic for well-known library families. If it recognizes the prefix confidently, it labels. If not, just "not in index." Better to label 40% accurately than label 90% with some wrong. Let me build it. Charted implementation roadmap for call inventory feature with provenance labeling Charted implementation roadmap for call inventory feature with provenance labeling Check argparse for where to add --call-inventory Let me add the --call-inventory flag and implement it.

Code exam phase9i callinventory TAR Looks like --call-inventory not in help Looks like /call-inventory not in interactive help, and cmd not availabe It sure works from the cmdline: C:\work\code_exam\Nodejs_port\code-exam>node src\index.js --index-path \work\ai_code_exam\.spinellis --call-inventory Loading large literal index (streaming)...

Wow, that's a lot. I think maybe with .spinellis (a huge collection of open source that came on CD-ROM with Spinellis's book Code Reading), I have selected a random subset of all the files? Possible, but 23,546 files doesn't sound like a number I would have picked. Maybe I chose 30,000 random files, and ~6,500 of them were not indexable? Anyway, a little concerned here, but I should just test with smaller known indexes (our code) and ones where I took the whole thing. C:\work\code_exam\Nodejs_port\code-exam>node src\index.js --index-path .CodeExam_tar --call-inventory Loaded existing index: 29 files Call inventory: scanning ALL functions... Scanned 295 functions Call inventory: 295 functions scanned 634 unique call targets: 260 in index, 374 external === EXTERNAL — not in index (374 targets) === [Python builtin] (12 functions, 161 call sites) exec, filter, format, hash, len, +7 more [C stdlib (math)] (7 functions, 130 call sites) .... How do I get a list of the ones that ARE in the index? There ought to be a Tip at the bottom suggesting they also run the --entry-points and --gaps command to see functions implemented but rarely/never called, and "suspicious dead code" (I forget how diff from --entry-points). But that assumes user ran --call-inventory in order to focus on the "EXTERNAL — not in index" part. Should there be a --missing option to just get those? No, there's --verbose , which lets me see: === IN INDEX (260 targets) === _ensureFunctionIndex ...code-exam/src/core/CodeSearchIndex.js (20L) (called by 18 functions) displayName ...e-archives.tar!code-exam/src/utils.js (13L) (called by 17 functions) listFunctions ...code-exam/src/core/CodeSearchIndex.js (29L) (called by 13 functions) eprint ...e-archives.tar!code-exam/src/utils.js (8L) (called by 11 functions) getFunctionSource ...code-exam/src/core/CodeSearchIndex.js (144L) (called by 9 functions) ..... I like "call sites" rather than "calls", because "call sites" indicates these are static code locations. We had some issues earlier with language that suggested "this function is frequently called" or something, when we've no idea about dynamic run-time behavior, and all our counts like that are about static "call sites" as you put it. Would there a point in at least simple ordering/ranking from ones with the most call sites, to the least? That array of PROVENANCE_PATTERNS is impressive. I don't even want to think how long it would have taken me to create something half as thorough. --call-inventory OpenGL doesn't work: expecting a function name, not a pattern. Maybe should accept pattern? No, wait, you told me there's --filter. Yep, that works: === EXTERNAL — not in index (60 targets (filtered by "OpenGL")) === glDisable (OpenGL) [13 call sites] glEnable (OpenGL) [13 call sites] glBindTexture (OpenGL) [12 call sites] .... Once again, amazing to have a whole big piece of functionality whipped up in a few minutes. Show more 8:25 PM Catalogued feature requests and documentation gaps systematically Catalogued feature requests and documentation gaps systematically Good catches. Let me fix the help, interactive mode, tips, and make sure ordering by call sites is consistent throughout. Extracted exact text from file for reference Extracted exact text from file for reference Claude's response was interrupted Sorry to interrupt, but I just realized that if --call-inventory has a Tip telling them about --gaps, then --gaps really must have a Tip telling them about --call-inventory too . 8:27 PM Reconciled bidirectional cross-referencing between related command tips Reconciled bidirectional cross-referencing between related command tips Absolutely right — they're two sides of the same coin. --gaps finds code that exists but nobody calls; --call-inventory finds calls to code that doesn't exist (in the index). Let me fix all four things: help text, interactive mode, tips on both commands, and I'll clean up the call-sites ordering while I'm at it. Recognized inconsistency and corrected bidirectional cross-reference documentation Recognized inconsistency and corrected bidirectional cross-reference documentation It's not in the interactive help. Let me use the exact text: Pondered reciprocal tip implementation between command options Pondered reciprocal tip implementation between command options Now add the command handler. Let me find the callees handler: Reconciled cross-referencing tips between two command options Reconciled cross-referencing tips between two command options Now fix the tips. First, update --call-inventory tips: Identified need for reciprocal cross-reference between command tips Identified need for reciprocal cross-reference between command tips Now find --gaps to add the cross-reference: Examined cross-reference consistency between command-line options Examined cross-reference consistency between command-line options Now add tip to --entry-points too: Recognized need for reciprocal cross-references between command options Recognized need for reciprocal cross-references between command options Now let me also add a usage example to the help: Recognized reciprocal relationship between documentation features Recognized reciprocal relationship between documentation features Already done! I added it in the edits just above. Here's what's now in place: --gaps tip (metrics.js): See also: --call-inventory (external dependencies not in the index) --entry-points (largest uncalled functions) --entry-points tip (metrics.js): See also: --gaps (suspicious dead code), --call-inventory (external dependencies) --call-inventory tip (callers.js): See also: --entry-points (uncalled functions), --gaps (suspicious dead code) All three now cross-reference each other — a little triangle of "code that's called but missing," "code that exists but isn't called," and "code that exists but looks dead." Let me run the suite and package: Recognized reciprocal documentation need between related features Recognized reciprocal documentation need between related features Interactive mode works too. Verified bidirectional cross-references between related command tips Verified bidirectional cross-references between related command tips 389/389. This tarball now has the complete set of fixes: --help text, interactive /call-inventory command, and the three-way cross-reference tips between --call-inventory, --gaps, and --entry-points. Code exam phase9i callinventory TAR Looks great. Tiny nit: interactive, I can specify -v but --filter doesn't seem to work. Don't fix now. I bet I'll collect a bunch of small things and you can knock them out in one tar. There was another small thing from earlier in this session, I forget now what it was. Anyway, this is terrific, and enough for now. Tomorrow it's going to be Task 3 (load multiple indexes), 4 (tree-sitter), or the big one, Task 8 (starting on an interactive GUI interface). 8:40 PM Catalogued known bugs and prioritized upcoming development tasks Catalogued known bugs and prioritized upcoming development tasks Noted on the /call-inventory filter= issue — I see the bug: iargs() passes filter: filterPat but the interactive iargs helper might not be propagating it into the args object the same way the CLI does. Quick fix next time. For the "other small thing from earlier" — if it comes back to you, jot it down. Otherwise I can grep the transcript tomorrow to find any loose ends. Good session. Recap of what shipped today: Task What Tests 7 Callee disambiguation: 6-level resolver + inheritance chain walking +21 5 Multisect class-level scope (cross-file C++ classes, dedup, file suppression fix) +11 6 --call-inventory with provenance labeling, interactive mode, cross-ref tips +22 389/389 tests, 22,661 lines. For tomorrow — Task 8 (GUI) would be the splashiest, Task 3 (multi-index) the most architecturally consequential, Task 4 (tree-sitter) the most incremental improvement. Your call which itch to scratch first. Claude is AI and can make mistakes. Please double-check responses.
