No DB writes, no UI.** + +--- + +## Current state (Phase 0 — DONE) + +The boilerplate is wired and runnable end-to-end as a skeleton: + +- `services/parser/cmd/parser/main.go` — wires `clone.Prepare → ts.Extract → (Phase 2 stub)`. +- `services/parser/internal/clone/clone.go` — local path or `git clone --depth 1`; never runs install/build. +- `services/parser/internal/security/` — `Config` (env-driven caps: 1MB/file, 50k files, depth 25, skip `node_modules/.git/dist/build/coverage/.next`), `ContainsRoot` (symlink/`..` guard), `Walk` (cap-enforcing file enumerator). +- `services/parser/internal/security/path_test.go` — existing `TestContainsRootRejectsEscape`. +- `services/parser/internal/ts/extract.go` — initializes tree-sitter-typescript language/parser, walks files, reads `.ts/.tsx`, but **only records path — no queries run yet** (`_ = parser.Parse(...)`). +- `services/parser/internal/ir/ir.go` — `File`, `Function`, `CallSite`, `Import`, `Graph` structs (mirrors `DATA_MODEL.md`). +- `services/parser/queries/typescript.scm` — query stubs for `function_declaration`, `method_definition`, `call_expression`, `import_statement`/`export_statement` **(Go side does not load these yet)**. +- `services/parser/internal/resolver/resolver.go` — confidence constants + `Resolve()` that marks everything `unresolved` (Phase 2 fill-in). +- `services/parser/internal/db/writer.go` — pgx pool + sqlx connection; `WriteGraph` is a no-op (Phase 2). +- `services/parser/migrations/0001_init.sql` — full schema (repos/files/functions/edges + indexes + `ON DELETE CASCADE` + `parsed_commit`/`updated_at`). +- `services/parser/testdata/sample/repo.ts` — tiny sample with function, class method, call. + +So Phase 1 = **make `ts.Extract` actually extract**, harden isolation for real-world repos, and prove it with tests + a Docker image that runs the hardened config. + +--- + +## Task 1 — Finish the tree-sitter query-to-IR extraction *(core of the phase)* + +**File:** `services/parser/internal/ts/extract.go` (extend), possibly new `services/parser/internal/ts/queries.go`. + +1. Load `queries/typescript.scm` → compile queries against the TypeScript language via `tree_sitter.Query` / `QueryCursor`. (Decide: parse the `.scm` file at runtime, or hand-build queries in Go. Runtime load is more maintainable; hand-built is simpler. **Recommend runtime `.scm` load** so queries stay editable without recompiling.) +2. For each `.ts/.tsx` file, wrap `tree_sitter.NewLanguage` + `parser.Parse(src, nil)` to get a `Tree`, then run each query against the AST. +3. Populate `ir.Function` for each match: + - `Name` from `@function.def` capture. + - `StartLine`/`EndLine` from the declaration node's byte range → line (use `tree.ByteOffsetForPoint` / node start/end rows). + - `Source` = slice of `src` between `StartLine`-1 and `EndLine` (trim to actual lines; keep as the full text of the function). + - `QualifiedName` = scoped name (see Task 2). + - `OverloadIndex` = 0 for now; only increment if you detect TS-style overloads (signatures with same name in one file). **Decision needed**: detect overloads now or defer to Phase 2? Recommend: record `(name, startLine)` now and resolve overload index in a post-pass — keep Phase 1 simpler. + - `PackagePath` = the file's directory path relative to repo root (e.g. `src/components`). Derive from `ir.File.Path`. +4. Populate `ir.CallSite` for each `@function.call` capture: + - `CalleeName` from the identifier / `property_identifier`. + - `CallerQualified` = the enclosing function's qualified name (walk up the AST from the call node to the nearest `function_declaration`/`method_definition`/`arrow_function`/`function_expression`). For top-level calls with no enclosing function, use a synthetic caller like `` or leave empty — **pick a convention and document it**. + - `Line` from the call node's start row. +5. Populate `ir.Import` for `@import.from`: `From` = the string literal value (strip quotes), `Symbol` = the imported names (parse `import_statement`'s clause: default, named, namespace). Store the set of imported local names so the resolver can match. +6. Return a fully-populated `ir.Graph{Files, Functions, Calls, Imports}`. + +**Edge cases to handle (and write tests for):** +- Comments and strings inside function bodies must NOT be mistaken for calls/defs — tree-sitter handles this natively (queries match nodes, not text), but verify. +- Nested functions (a function declared inside another) — do you capture the inner one as its own `ir.Function` with a deeper `QualifiedName`? **Yes**, per `DATA_MODEL.md` overload note. Decide qualified-name format, e.g. `outer.inner`. +- Arrow functions / function expressions assigned to `const`/`let` — the current `.scm` only matches `function_declaration` + `method_definition`. **Add**: `variable_declarator` under `lexical_declaration`/`variable_declaration` where the value is `arrow_function`/`function_expression`. Capture the variable name as `@function.def`. +- Generator functions (`function*`) and async functions (`async function`) — tree-sitter wraps them; confirm the `function_declaration` query still matches (it should). +- `.tsx` files (JSX) — same grammar branch `LanguageTSX` may be needed alongside `LanguageTypescript`. Confirm the binding exposes both; if not, pick the TS grammar and accept JSX may parse coarsely. + +**Done when:** running `make go-run REPO=./services/parser/testdata/sample` prints (and can dump as JSON) the correct `Function` rows for `getUser`, `fetchName`, `Repo.sync`, and the correct `CallSite` for `getUser(1)` inside `Repo.sync` and `fetchName(id)` inside `getUser`. + +--- + +## Task 2 — Qualified-name scoping convention + +**File:** `services/parser/internal/ts/extract.go` (or a small `scope.go` helper); document in `docs/PARSING_STRATEGY.md`. + +1. Define the format for `QualifiedName`. Proposed: dot-joined path of enclosing scopes → name, e.g.: + - top-level `fetchName` → `fetchName` + - method `Repo.sync` → `Repo.sync` + - nested `fn` declared inside `getUser` → `getUser.fn` +2. Implement an "enclosing scope" walk: from a node, climb parents collecting `class_declaration`/`function_declaration`/`method_definition`/`arrow_function` names; join with `.`. +3. Make `package_path` = directory path of the file relative to repo root (no leading `./`, use `/`). For files at repo root, `package_path = ""` or `"."` — **pick one and use it consistently in queries**. Recommend `""`. +4. Add a unit test that parses a fixture with nesting and asserts the qualified names. + +**Done when:** `functions.qualified_name` is unique per `(file, qualified_name)` in the sample, matching what the Phase 2 resolver + the DB `UNIQUE` constraint expect. + +--- + +## Task 3 — Harden `security.Walk` for real-world repos + +**File:** `services/parser/internal/security/path.go`, `config.go`, new `security_test.go`. + +The current `Walk` enforces caps but has gaps flagged in `PLAN.md` §1.3: + +1. **No symlink follow / symlink rejection.** `filepath.WalkDir` follows symlinks by default for the walked path; verify behavior and add an explicit `os.Lstat` check: if `info.Mode() & os.ModeSymlink != 0`, either skip or hard-fail. **Recommend: hard-fail** (return error) for any symlink under root, since untrusted repos shouldn't have legitimate symlinks in a path we're about to parse. Add a test: a fixture dir with a symlink to `/etc/hostname` must cause `Walk` to error (and never readlink it). +2. **Binary/non-text skip.** Before reading a file, sniff the first ~512 bytes for NULs (`bytes.IndexByte(buf, 0) != -1` → binary, skip). Don't rely on extension alone (a `.ts` file could be gibberish, a weird extension could be text). +3. **`.gitignore` respect (stretch / optional).** The skip-list already covers the big offenders (`node_modules`, `dist`, etc.). Respecting `.gitignore` adds correctness but ~complexity. **Decision:** defer to post-MVP unless a test repo fails because of it. Note the decision in `docs/RISKS.md`. +4. **Depth calc is fragile.** `strings.Count(path, sep) - strings.Count(root, sep)` breaks if `root` has trailing slash or symlinks. Replace with `filepath.Rel(root, path)` and count separators in the rel path. Less error-prone. +5. **File-count cap logging is informational only.** Add an explicit error return (or sentinel) so the caller can distinguish "capped" from "clean walk." Useful for queue later. +6. **Tests:** add `TestWalkSkipsBinary`, `TestWalkRejectsSymlinkOutsideRoot`, `TestWalkRespectsFileCountCap`, `TestWalkRespectsDepth`. + +**Done when:** `go test ./internal/security/...` is green and covers every gap above. + +--- + +## Task 4 — Pre-read size cap enforcement at the read site + +**File:** `services/parser/internal/ts/extract.go`. + +`security.Walk` already skips files over `MaxFileBytes` in the directory walk, BUT `extract.go` does `os.ReadFile(p)` directly which re-reads regardless of size and has no bound. Fix: + +1. Before `os.ReadFile`, `os.Stat` and reject files > `cfg.MaxFileBytes` (log + skip, don't fail the whole run). +2. Use a bounded read (`io.LimitReader`) so a file that grows between the stat and the read can't OOM you. Belt + suspenders. +3. Skip files binary-detected at read time (Task 3's sniffer), reused here. + +**Done when:** a 5MB `.ts` fixture is skipped with a warning, not read in full. + +--- + +## Task 5 — `ts.Extract` returns a `Graph` and `main.go` dumps JSON + +**File:** `services/parser/cmd/parser/main.go`, possibly `services/parser/internal/ts/extract.go` signature change. + +1. Change `extract.go`'s return type from `[]ir.File` to `ir.Graph` (populated in Task 1). +2. In `main.go`, after `ts.Extract(...)`, marshal `graph` to JSON and write to `out.json` (or stdout when a `--out` flag is `/dev/stdout`). Keep the Phase 2 `db.Writer` reference intact behind a flag or comment so you don't lose the wiring. +3. Add a `--format json|summary` flag: `summary` prints counts (`files`, `functions`, `calls`, `imports`) for quick sanity checks. +4. Confirm the sample run output matches expectations from Task 1's "done when." + +**Done when:** `make go-run REPO=./services/parser/testdata/sample` writes a complete `out.json` with the expected functions/calls/imports, and `--format summary` prints human counts. + +--- + +## Task 6 — Expand `testdata/` into a realistic regression corpus + +**File:** `services/parser/testdata/{sample,snake,imports,nested,edge}/...` (new dirs). + +The single `repo.ts` is too small to catch regressions. Add fixtures that each isolate one concern, plus an expected-output file the test asserts against: + +1. `testdata/sample/repo.ts` — existing; the happy path. +2. `testdata/nested/` — functions nested 3 levels deep; class with several methods; arrow consts. Assert qualified names. +3. `testdata/imports/` — default import, named import, namespace import, side-effect import, re-export, dynamic `import()`. Assert `ir.Import` rows. +4. `testdata/calls/` — local call, method call (`obj.method()`), chained call (`a.b.c()`), imported-symbol call, call inside string/comment (must NOT be captured), call inside arrow callback. +5. `testdata/overloads/` — TS signature overloads (same name, multiple declarations). Verify overload handling decision from Task 1. +6. `testdata/edge/` — empty file, file with only comments, file with a huge minified-looking single line (to exercise the size/binary caps), `.tsx` with JSX, a `.ts` file with a symlink sibling (symlink should be rejected, target parsed if real). +7. For each, add a `_expected.json` or expected counts; the test loads the repo, extracts, and diff-asserts. + +**Done when:** `go test ./internal/ts/...` runs against every fixture and passes. + +--- + +## Task 7 — Tree-sitter query tests (golden) + +**File:** `services/parser/internal/ts/extract_test.go` (new). + +1. Test that every node type you rely on (`function_declaration`, `method_definition`, `call_expression`, `import_statement`, `variable_declarator` with `arrow_function`/`function_expression`) actually matches the fixtures. If a grammar update ever drops a node type, this test breaks loudly. +2. Test that comments and string literals containing the word `function` or a call-shaped text do NOT produce spurious matches. +3. Test the qualified-name scope walk on the nested fixture (Task 2). + +**Done when:** all golden tests green; `go test ./...` from `services/parser` is clean. + +--- + +## Task 8 — Parser Docker image with enforced isolation + +**File:** `services/parser/Dockerfile`, `docker-compose.yml` (parser service block). + +The `Dockerfile` exists but needs to bake in the runtime constraints from `docs/SECURITY.md`: + +1. Multi-stage build: `golang:1.25` build → distroless/`alpine` runtime, **non-root user** (`USER nonroot`, UID 65532). +2. Install only `git` (for clone) in the runtime stage; nothing else. Remove shell if using distroless (then `git` must come from a build stage or you containerize clone differently). +3. Bake the `PARSER_*` env defaults into the image via `ENV` so even a misconfigured run is safe. +4. In `docker-compose.yml`, the `parser` service sets: + - `read_only: true` (read-only rootfs) + - `network_mode: none` (no network egress during parse — clone happens before entering parse, or via a sidecar; **decision needed**: how does `git clone` work with `network none`? Options: (a) clone in a separate one-shot container WITH network, then hand the volume to the parser container that runs with `network none`; (b) allow network only for clone phase. **Recommend (a)** — separate `parser-clone` and `parser-parse` containers sharing a tmpfs volume.) + - `cap_drop: [ALL]`, no `cap_add`. + - `tmpfs: [/tmp:size=100m]` for clones. + - `mem_limit`, `cpus` bounds. +5. Runtime entrypoint runs only `parse` (no clone) — clone is a separate step/or container. +6. Add a `make docker-run-parser REPO=./services/parser/testdata/sample` target that mounts the repo read-only and runs parse against the shared volume. + +**Done when:** `docker compose run --rm parser go run ./cmd/parser --repo /work/sample` runs as non-root, read-only rootfs, no network, and emits `out.json` successfully. Verify with `docker inspect` that `NetworkMode=none` and `Cap` is empty. + +--- + +## Task 9 — CI for the parser + +**File:** `.github/workflows/ci.yml` (new or update existing). + +1. Job `parser`: `setup-go@v5`, `go mod tidy` check, `go vet ./...`, `go test -race ./...`, `go build ./...`. +2. Cache `~/go/pkg/mod` and the build cache. +3. Job `migration-check`: pull `golang-migrate/migrate` image, spin up Postgres via `services:`, run `migrate -path services/parser/migrations -database $DATABASE_URL up`, then assert tables exist. (This guards the schema even though DB writes are Phase 2.) +4. Don't gate on the TS app yet — keep it parser-only so CI is green while you work. + +**Done when:** a PR touching `services/parser/**` runs all three jobs and they pass on the sample repo. + +--- + +## Task 10 — Docs sync + +**Files:** `docs/PARSING_STRATEGY.md`, `docs/RISKS.md`, `docs/SECURITY.md`. + +1. In `PARSING_STRATEGY.md`: write the actual qualified-name convention (Task 2), the query-loading approach (runtime `.scm`), and the known limitations you hit (arrow functions, JSX, dynamic imports). +2. In `RISKS.md`: close/update risks R1–R18 that Phase 1 resolves (e.g. R1 naming → decision recorded; symlink/cap risks → closed; overload handling → decision recorded). Add any new risks discovered. +3. In `SECURITY.md`: replace aspirational bullets with the **implemented** controls (non-root, `--network none`, read-only, no symlink, size/count/binary caps) and the clone-vs-parse container split decision. +4. Update `DEVELOPMENT.md` "Phase 1" section with the exact commands now that they exist. + +**Done when:** docs match the code; no aspirational "TODO" bullets in the Phase 1 sections. + +--- + +## Definition of Done — Phase 1 + +All of the following pass: + +- [ ] `make go-run REPO=./services/parser/testdata/sample` emits a correct `out.json`. +- [ ] `make go-test` is green across `internal/security`, `internal/ts` (all fixtures). +- [ ] `make go-vet` clean. +- [ ] `docker compose run --rm parser ...` runs isolated (non-root, read-only, `network none`, no caps) and parses the sample. +- [ ] Symlink-to-escape fixture is rejected; 5MB file is skipped; binary file is skipped — all via tests. +- [ ] CI workflow green on a PR. +- [ ] `docs/PARSING_STRATEGY.md`, `docs/RISKS.md`, `docs/SECURITY.md` reflect implemented behavior. + +--- + +## Naming/status notes (carry from Phase 0) + +- **Open decision — overload index:** detect at extraction or at resolution? Recommend **extraction with a post-pass per file** (count same-`qualified_name`, assign `overload_index` 0..n-1). +- **Open decision — `.scm` runtime load vs hand-built queries:** Recommend **runtime load** so queries stay editable without recompiling Go. +- **Open decision — `.gitignore` respect:** Defer unless a test repo needs it; record in `RISKS.md`. +- **Open decision — clone vs parse containers with `network none`:** Recommend **separate clone container WITH network → shared tmpfs → parse container with `network none`**. +- **Still deferred to Phase 2** (don't build these now): DB writes (`db.Writer.WriteGraph`), the resolver algorithm (`resolver.Resolve` confidence tagging), Drizzle read-side, API graph endpoints. +- **Naming** (`funcatlas` repo vs `CodeCanvas` product) is still unresolved — not blocking Phase 1, but resolve before any OAuth app / image tag creation (Phase 3).

Handle named function expressions where +present. Treat the variable name as the function name. +**Good when:** a fixture with `const greet = (n) => {...}` and `let f = function(){}` extracts two +`Function` rows with the variable name as `Name`. +**Watch outs:** matching `variable_declarator` whose value is *not* a function (e.g. a plain +object) — your query must require the `arrow_function`/`function_expression` child; arrow bodies +that are single *expressions* (no `statement_block`); async/generator modifiers. + +### C4 — Qualified-name scope walk `[ ]` +**Approach:** Add `services/parser/internal/ts/scope.go` with `func qualifiedName(node Node) string` +that walks parents collecting `class_declaration`/`function_declaration`/`method_definition`/ +`arrow_function`/`function_expression` names (the variable name for arrows), then joins with `.`. +Convention (lock into `docs/PARSING_STRATEGY.md` in C14): +- top-level function → bare `Name` (e.g. `getUser`); +- class method → `Repo.sync`; +- nested function → `getUser.inner`; +- module-level call (no enclosing function) → caller `qualified_name = ""`; +- `package_path` = `filepath.Dir(rel)` relative to repo root, `""` at repo root. +**Good when:** a `testdata/nested/` fixture produces qualified names `Repo.sync`, `Repo.sync.cb`, +`getUser`, `getUser.inner` (assert in C11). +**Watch outs:** order of parent walk (innermost scope first) — join in reverse so outer comes +first; arrow functions where the "name" lives on the `variable_declarator`, not on the arrow node; +anonymous functions nested with no enclosing name (use a placeholder like `` and +document it). + +### C4b — Overload `overload_index` post-pass (future-proof) `[ ]` +**Approach:** After building the per-file `[]ir.Function`, run `assignOverloadIndices(funcs)`: +group by `qualified_name`, sort each group by `start_line` ascending, assign `overload_index = +0..n-1`. Single-declaration `qualified_name`s get `0`. Because the scope walk (C4) already gives +different `qualified_name`s to same-name-different-scope functions, those do **not** collide and +each gets `0` — only genuine TS overloads (same `qualified_name`, several declarations) get +0,1,2,… +**Why future-proof (decision locked in `PRD.md` §11):** `overload_index` is part of the DB +`UNIQUE (file_id, qualified_name, overload_index)` key, so Phase 4's delete-then-reinsert +incremental relink never hits a `UNIQUE` collision; keyed by `start_line` ⇒ stable across identical +re-parses (no flapping rows on webhook updates). Phase 2's resolver tags edges to overloaded +`qualified_name`s `unresolved` (R8) — no rework later. +**Good when:** `(file, qualified_name)` is unique in every fixture output; an `overloads/` +fixture with two `fetch` declarations yields `overload_index` 0 and 1. +**Watch outs:** mutating the slice in place vs. building a map — be consistent; off-by on `n`; not +re-running the pass when a chunk re-extracts a file later. + +### C5 — Populate `ir.CallSite` with `CallerQualified` `[ ]` +**Approach:** For each `@function.call` capture, set `CalleeName` = identifier / property name, +`Line` = call node start row, `CallerQualified` = `qualifiedName(enclosingFunction)` (reuse C4's +walk from the call node up to the nearest function ancestor). Module-level call (no enclosing +function) → `CallerQualified = ""`. +**Good when:** `testdata/calls/` fixture yields `CallSite`s for local calls, `obj.method()`, +chained `a.b.c()`, and a call inside an arrow callback — with correct `CallerQualified`. +**Watch outs:** not actually walking up (off-by parent index); member calls vs. identifier calls +(`@function.call` matches both via the `[…]` alternation — verify the capture lands on the right +sub-node); calls inside comments/strings must NOT match (tree-sitter node matching handles this, +but verify with a fixture). + +### C6 — Populate `ir.Import` `[ ]` +**Approach:** Parse `import_statement` clauses: default (`import x from "y"`), named +(`import {a, b} from "y"`), namespace (`import * as ns from "y"`), side-effect (`import "y"`), +re-export (`export … from "y"`), and dynamic `import("y")`. `From` = string literal value (strip +quotes); store the set of imported local names on `ir.Import` so the Phase 2 resolver can match. +Add a field to `ir.Import` if needed (e.g. `Symbols []string`, `IsDefault bool`, `Namespace string`). +**Good when:** `testdata/imports/` fixture yields `Import` rows with the right `From` and local names. +**Watch outs:** dynamic `import()` is a *call_expression* with a string arg, not an +`import_statement` — handle separately or skip and document; named-import aliases +(`{a as b}`) — local name is `b`; re-exports that don't bind a local name. + +### C7 — Return `ir.Graph`; `main.go` JSON dump + `--format summary` `[ ]` +**Approach:** Change `extract.go`'s return from `[]ir.File` to `ir.Graph`. In `main.go`, marshal +`graph` to JSON → write to `--out` (default `out.json`, `/dev/stdout` for streaming). Add +`--format json|summary`; `summary` prints counts (`files`, `functions`, `calls`, `imports`). Keep +the `db.NewWriter` reference intact behind a comment so Phase 2 wiring isn't lost. +**Good when:** `make go-run REPO=./services/parser/testdata/sample` writes a complete `out.json` +with the expected functions/calls/imports, and `--format summary` prints human counts. +**Watch outs:** leaving the `db.Writer` import unused (Go will refuse to compile) — keep a +`var _ = db.NewWriter` like `config.go` does, or move it behind a flag; `os.WriteFile` perms. + +### C8 — Harden `security.Walk` `[ ]` +**Approach:** (1) **Symlink hard-fail** — in `Walk`, before accepting any path, `os.Lstat` and +return error if `info.Mode() & os.ModeSymlink != 0` (do not readlink). (2) **Binary sniff** — read +first ~512 bytes, skip if `bytes.IndexByte(buf, 0) != -1`. (3) **Fix depth** — replace +`strings.Count(path, sep) - strings.Count(root, sep)` with `filepath.Rel(root, path)` and count +separators (robust to trailing slash / symlinked roots). (4) **Cap sentinel** — return a typed +error (`ErrFileCapReached`) so Phase 4's queue can distinguish "capped" from "clean walk". +Add tests: `TestWalkSkipsBinary`, `TestWalkRejectsSymlinkOutsideRoot`, `TestWalkRespectsFileCountCap`, +`TestWalkRespectsDepth`. +**Good when:** `go test ./internal/security/...` is green and covers every gap above. +**Watch outs:** `filepath.WalkDir` follows symlinks for the *walked* path — the Lstat guard must +catch symlinks inside the tree, not just the root; `SkipDir` vs. `SkipAll` semantics; reading 512 +bytes for every file is cheap but measure; **decision not to respect `.gitignore`** — note in +`docs/RISKS.md` during C14. + +### C9 — Bounded read at read site `[ ]` +**Approach:** In `extract.go`, before reading a file, `os.Stat` and skip (log + continue) if size +> `cfg.MaxFileBytes`; then read with `io.LimitReader` bound to `MaxFileBytes+1` so a file that grows +between stat and read can't OOM you; also reuse C8's binary sniff at read time. Belt + suspenders. +**Good when:** a 5MB `.ts` fixture is skipped with a warning, never read in full. +**Watch outs:** `io.LimitReader` returns fewer bytes — handle the EOF cleanly; reconciling C8's +size check (already done in `Walk`) with this one — keep both (Walk gates discovery, read gates the +actual read); not logging path + reason consistently. + +### C10 — Fixtures `[ ]` +**Approach:** Add under `services/parser/testdata/`: +- `nested/` — 3-level nesting + class methods + arrow consts (drives C4 assertions); +- `imports/` — default/named/namespace/side-effect/re-export/dynamic `import()` (drives C6); +- `calls/` — local, `obj.method()`, chained `a.b.c()`, imported-symbol call, call in string/comment + (must NOT capture), call inside arrow callback (drives C5); +- `overloads/` — two `fetch` declarations (drives C4b); +- `edge/` — empty file, only-comments file, a huge minified-looking single line (size cap), `.tsx` + with JSX (grammar branch), a `.ts` file with a symlink sibling (symlink rejected, target parsed + if real — drives C8). +For each, add `_expected.json` (or expected counts) that the test in C11 diff-asserts. +**Good when:** every fixture parses and dumps an `out.json` matching its `_expected.json`. +**Watch outs:** Windows line endings in fixtures (normalize `\n`); JSX mandating the `LanguageTSX` +binding — verify the `tree_sitter-typescript/bindings/go` exposes both; huge-line fixture must be +*under* the size cap or its purpose (size test) is moot. + +### C11 — Golden `extract_test.go` `[ ]` +**Approach:** Table-driven tests over the C10 fixtures asserting: every node type we rely on +(`function_declaration`, `method_definition`, `call_expression`, `import_statement`, +`variable_declarator` with arrow/fn-expr) actually matches; comments and string literals +containing the word `function` or call-shaped text produce **no** spurious matches; qualified-name +scope walk on `nested/` matches expectations (C4); overload indices on `overloads/` are `0,1` (C4b). +**Good when:** all golden tests green; `cd services/parser && go test ./...` clean. +**Watch outs:** golden JSON that records unstable fields (absolute paths, byte sizes) — keep only +rel paths + structural fields; not regenerating goldens when queries intentionally change. + +### C12 — Hardened parser Docker image `[ ]` +**Approach:** Multi-stage `Dockerfile`: `golang:1.25` build → distroless/alpine runtime, `USER +nonroot` (UID 65532), only `git` in runtime. Bake `PARSER_*` env defaults via `ENV`. In +`docker-compose.yml` add a `parser` service with `read_only: true`, `network_mode: none`, +`cap_drop: [ALL]`, `tmpfs: [/tmp:size=100m]`, `mem_limit`, `cpus`. **Clone/parse split** per the +locked decision: a `parser-clone` one-shot container (network enabled) clones into a shared tmpfs; +the `parser-parse` container runs `--network none` against that volume. Add +`make docker-run-parser REPO=./services/parser/testdata/sample`. +**Good when:** `docker compose run --rm parser …` runs as non-root, read-only rootfs, no network, +no caps, and emits `out.json`; `docker inspect` shows `NetworkMode=none` and empty `Cap`. +**Watch outs:** distroless has no shell → `git` must come from a build stage or you containerize +clone differently; `read_only: true` fights any code that writes to rootfs (only `/tmp` is +writable via tmpfs); the parser-clone sidecar forgetting to clean the tmpfs between runs. + +### C13 — CI for the parser `[ ]` +**Approach:** Update `.github/workflows/ci.yml`: +- `parser` job: `setup-go@v5`, `go mod tidy` check, `go vet ./...`, `go test -race ./...`, + `go build ./...`; cache `~/go/pkg/mod` + build cache. +- `parser-sample` job: build the binary, run `--repo ./services/parser/testdata/sample + --format summary`, assert `functions > 0` and `calls > 0` from the printed counts. +- `migration-check` job: pull `golang-migrate/migrate`, start Postgres via `services:`, run + `migrate -path services/parser/migrations -database $DATABASE_URL up`, assert the four tables + exist. (DB writes are Phase 2, but this guards the schema now.) +**Good when:** a PR touching `services/parser/**` runs all three and they pass on the sample repo. +**Watch outs:** CGO is required by `tree-sitter` (already installed in the existing `go` job); +`go mod tidy` check needs `GOFLAGS=-mod=mod` or it can falsely fail; the migration job must not +leave Postgres running. + +### C14 — Docs sync `[ ]` +**Approach:** +- `docs/PARSING_STRATEGY.md`: write the `qualified_name` convention (C4), `overload_index` post-pass + (C4b), the runtime `.scm` load approach (C1), and known limitations hit (arrows, JSX, dynamic + `import()`). +- `docs/RISKS.md`: flip R9 OPEN → DECIDED (Go IR is native — `internal/ir/ir.go`), R16 OPEN → + DECIDED (pin the grammar version named in `go.mod`); record the R8 decision (edges to overloaded + `qualified_name`s → `unresolved`) and the `.gitignore` DEFER decision. +- `docs/SECURITY.md`: replace aspirational bullets with the **implemented** controls (non-root, + `--network none`, read-only rootfs, no caps, no symlink follow, size/count/binary caps) and the + clone-vs-parse container split. +- `DEVELOPMENT.md`: refresh the Phase 1 section with the real commands now that they exist. +**Good when:** docs match the code; no aspirational "TODO" bullets in any Phase 1 section. +**Watch outs:** stale `ARCHITECTURE.md` still mentions Excalidraw in the canvas diagram — leave a +note that it's deferred; the `samples` for ` qualified_name` must match exactly what C4 produces. + +--- + +## Phase 1 exit gate (Definition of Done) + +All of the following pass: +- [ ] `cd services/parser && go test ./...` green — `internal/security` + `internal/ts` (all + fixtures) + golden tests. +- [ ] `make go-run REPO=./services/parser/testdata/sample` emits a correct `out.json`. +- [ ] `make go-vet` clean. +- [ ] `docker compose run --rm parser …` runs isolated (non-root, read-only rootfs, `network none`, + no caps) and parses the sample. +- [ ] Negative tests green: symlink-to-escape rejected; 5MB file skipped; binary file skipped. +- [ ] CI workflow green on a PR (parser + parser-sample + migration-check jobs). +- [ ] `docs/PARSING_STRATEGY.md`, `docs/RISKS.md`, `docs/SECURITY.md`, `DEVELOPMENT.md` reflect + implemented behavior — no aspirational TODOs. + +--- + +## Working conventions (so we pair smoothly) + +- **You code, I debug.** Submit a chunk via your usual edit; I'll review for: correctness vs. + IR/schema/contract → bugs (byte→line, off-by-one, nil, OS path separators, false captures) → + style/duplication (e.g. reuse the C4 scope walk in both `Function` C2/C4 and `CallSite` C5) → + tests (table-driven, one-concern fixtures, golden JSON diffs) → nudge to the next chunk. +- **Commits:** imperative, one concern each (e.g. `add parser symlink hard-fail`), scoped to the + chunk.
