Merge remote-tracking branch 'origin/main' into pr-179-merge

feat(python): index module-level singleton instances as CodeElement nodes
- Add definition.instance query to PYTHON_QUERIES, anchored to module scope with call on right-hand side - Add definition.instance to DEFINITION_CAPTURE_KEYS and label maps in both sequential (parsing-processor.ts) and worker (parse-worker.ts) paths - Compose with #137: instances are now linkable targets for File->Symbol IMPORTS edges created by symbol-level import resolution

-# GitNexus PR Reviewer Swarm — Claude Code adapter
-
-This is the **Claude Code** entrypoint for the cross-CLI GitNexus PR reviewer swarm. The
-review logic itself is CLI-neutral and lives in **[`pr-swarm-review/`](../pr-swarm-review/README.md)**
-— that README is the canonical guide and covers every CLI (Claude Code, Gemini, Copilot,
-Cursor, Codex, and any AGENTS.md-aware agent).
-
-## Invocation (Claude Code)
-
-```
-/gitnexus-pr-swarm-review <PR URL or PR number>
-```
-
-Runs in **Swarm mode**: the coordinator skill dispatches the seven `gitnexus-*` subagents in
-parallel (lanes 1–2 first, 3–6 in parallel, lane 7 last as a hard gate).
-
-## Files in this adapter
-
-| File | Role |
-|------|------|
-| `.claude/skills/gitnexus-pr-swarm-review/SKILL.md` | Coordinator — runs Swarm mode per `pr-swarm-review/orchestration.md` |
-| `.claude/agents/gitnexus-*.md` | Seven thin subagent wrappers; each reads its canonical persona in `pr-swarm-review/personas/` |
-
-Each subagent keeps valid Claude Code frontmatter (model, tools, etc.); the mechanical
-verifier lanes (`test-ci-verifier`, `branch-hygiene-reviewer`) run on Haiku, the analytical
-lanes on Sonnet.
-
-## Key properties
-
- **Read-only.** Tools limited to Read/Grep/Glob/Bash, and every persona enforces an
-  explicit permitted/prohibited Bash list. No agent edits files, commits, or posts.
- **Evidence-grounded**; **missing visibility becomes verification work**; **manually invoked.**
-
-## Editing
-
-Edit review behavior in the canonical files under `pr-swarm-review/` (orchestration +
-personas), **not** in these wrappers. After adding or editing files in `.claude/agents/`,
-restart Claude Code so it reloads the agent definitions.
-
-## Relationship to `/gitnexus-pr-review`
-
-Coexists with the single-agent `/gitnexus-pr-review` skill (a linear checklist using GitNexus
-MCP tools). This swarm is the multi-persona deep production-readiness review.

-## Always Start Here
-
-For any task involving code understanding, debugging, impact analysis, or refactoring:
-
-1. **Read `gitnexus://repo/{name}/context`** — codebase overview + check index freshness
-2. **Match your task to a skill below** and **read that skill file**
-3. **Follow the skill's workflow and checklist**
-
-> If step 1 warns the index is stale, run `node .gitnexus/run.cjs analyze` in the terminal first.

-| ---------------- | ------------------------------------------------------------------------ |
-| `query`          | Process-grouped code intelligence — execution flows related to a concept |
-| `context`        | 360-degree symbol view — categorized refs, processes it participates in  |
-| `impact`         | Symbol blast radius — what breaks at depth 1/2/3 with confidence         |
-| `trace`          | Shortest path between two symbols — "how does A reach B?" in one call     |
-| `detect_changes` | Git-diff impact — what do your current changes affect                    |
-| `rename`         | Multi-file coordinated rename with confidence-tagged edits               |
-| `cypher`         | Raw graph queries (read `gitnexus://repo/{name}/schema` first)           |
-| `explain`        | Persisted taint findings — source→sink data flows (needs `analyze --pdg`) |
-| `pdg_query`      | Control/data dependence — what gates X (CDG) / where Y flows (REACHING_DEF); needs `analyze --pdg` |
-| `check`          | Check graph invariants such as circular imports                          |
-| `list_repos`     | Discover indexed repos (paginated — `limit`/`offset`)                    |
-
-### Paginating `list_repos`
-
-`list_repos` is paginated so a large registry is not truncated by MCP/LLM token limits. It takes optional `limit` (default **50**, max **200**) and `offset`, and returns:
-
-```jsonc
-{
-  "repositories": [
-    { "name": "...", "path": "...", "indexedAt": "...", "lastCommit": "...", "stats": { } }
-  ],
-  "pagination": {
-    "total": 437,
-    "limit": 50,
-    "offset": 0,
-    "returned": 50,
-    "hasMore": true,
-    "nextOffset": 50
-  }
-}
-```
-
-To enumerate **every** repository, keep calling with `offset` set to `pagination.nextOffset` until `hasMore` is `false`:
-
-```text
-list_repos {}               → repos 1–50,    nextOffset 50,  hasMore true
-list_repos { offset: 50 }   → repos 51–100,  nextOffset 100, hasMore true
-…
-list_repos { offset: 400 }  → repos 401–437,                 hasMore false   (done)
-```
-
-Notes: `offset` ≥ `total` returns an empty page (with `total` still reported). Out-of-range or malformed `limit`/`offset` (non-integer, `limit` outside `[1, 200]`, `offset < 0`) are rejected with a clear error — `limit` above the max is rejected, not silently capped. The order is deterministic (lower-cased name, then path), so paging never skips or duplicates an entry while the registry is unchanged.
-
-### Taint findings (`explain`)
-
-`explain` returns intra-procedural taint findings (`TAINTED` edges) recorded by `gitnexus analyze --pdg` — each with a sink category (command-injection, code-injection, path-traversal, sql-injection, xss), source/sink lines, and the ordered hop path with the variable carried on each hop.
-
- `explain {}` — enumerate all findings for the repo (bounded by `limit`, deterministic order)
- `explain { target: "src/vuln.ts" }` — findings in a file (suffix path match accepted)
- `explain { target: "runUserCommand" }` — findings in a function (resolved like `context`; ambiguous names return ranked candidates)
-
-A repo indexed without `--pdg` returns a clear "no taint layer" note. Caveats: findings are intra-procedural only — cross-function, closure/callback, property/field, and implicit flows are not modeled, so the absence of a finding is **not** proof of safety. `SANITIZES` (sanitizer-kill) edges are queryable via `cypher`.
-
-### Control & data dependence (`pdg_query`)
-
-`pdg_query` reads the control/data-dependence layers `gitnexus analyze --pdg` records (CDG + REACHING_DEF, basic-block granular) — the control/data analog of `explain`. It is **always anchored** (a `target` file path or symbol, resolved like `context`) and has two modes:
-
- `pdg_query { mode: "controls", target: "..." }` — CDG: "under what condition does X run?". Each edge is a controlling predicate block → dependent block with the branch sense (`'T'`/`'F'`) in `reason`; an edge into an early `return`/`throw` is flagged `guard: true` (guard-clause discovery — the sense depends on the predicate, so don't filter guards by a fixed label).
- `pdg_query { mode: "flows", target: "...", variable?: "..." }` — REACHING_DEF def→use edges within the function; pass `variable` to trace one binding.
-
-A repo indexed without `--pdg` returns a "no PDG layer" note (or "status unknown" when the layer can't be confirmed). Intra-procedural only — cross-function flow is taint's domain (`explain`). The raw CDG/REACHING_DEF edges are also queryable via `cypher`. See the `gitnexus-pdg-query` skill for the full query surface.
-
-### Shortest path between two symbols (`trace`)
-
-`trace` answers "how does A reach B?" in one call — the shortest directed path over `CALLS` (plus `HAS_METHOD`, so a class-rooted trace descends into its methods) instead of chaining 3–8 `context`/`impact` hops by hand.
-
- `trace { from: "validateUser", to: "executeQuery" }` — shortest path between two symbols.
- Disambiguate common names with `from_uid`/`to_uid` (zero-ambiguity) or `from_file`/`to_file`; an ambiguous name returns ranked candidates.
- `maxDepth` (default 10, max 30) bounds the search; `includeTests` (default false) lets the traversal pass through test-file symbols.
-
-Returns ordered `hops` (each `{ name, filePath, startLine }`) and an aligned `edges[]` of `{ relType, confidence }`, so call hops and containment (`HAS_METHOD`) hops stay distinguishable. When no path exists it reports the **furthest** reachable node (where the chain breaks) and sets `truncated: true` if a traversal cap was hit first. Every result carries a `status`: `ok` / `no_path` / `ambiguous` / `not_found` / `error`.
-
-## Resources Reference
-
-Lightweight reads (~100-500 tokens) for navigation:
-
-| Resource                                       | Content                                   |

-| `gitnexus://repo/{name}/clusters`              | All functional areas with cohesion scores |
-| `gitnexus://repo/{name}/cluster/{clusterName}` | Area members                              |
-| `gitnexus://repo/{name}/processes`             | All execution flows                       |
-| `gitnexus://repo/{name}/process/{processName}` | Step-by-step trace                        |
-| `gitnexus://repo/{name}/schema`                | Graph schema for Cypher                   |
-

On **npm 11.x**, if `npx` crashes during install (`node.target is null`), install once with `npm i -g gitnexus` (then `gitnexus analyze`) or use `pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze`.

Examples: \"what guards this statement?\", \"trace this variable within the function\", \"why is the pdg_query result empty?\", \"add a CDG query\"."

-
-# PDG query surface with GitNexus
-
-Expert knowledge for the `pdg_query` MCP tool and the control/data-dependence
-edges it reads — the opt-in `--pdg` program-dependence layers. Read this before
-touching `gitnexus/src/mcp/local/local-backend.ts` (`_pdgQueryImpl`) or the
-`pdg_query` tool def, or when explaining a `pdg_query` result.
-
-## When to Use
-
- "Under what condition does this statement run?" (guarding predicates).
- "Where does this variable flow inside the function?" (def→use).
- Guard-clause discovery (early-return guards — subsumes the #559 heuristic).
- Extending or reviewing `pdg_query` / the CDG / REACHING_DEF read path.
- Debugging an empty or surprising `pdg_query` result.
-
-## The layered substrate (build order)
-
-`pdg_query` runs **on** the same graph taint runs on. Each layer is opt-in
-behind `--pdg`; a default `analyze` run records none of them (byte-identical).
-
-```
-L1  CFG            per-function basic blocks + control-flow edges   (M1 #2081)
-L2  REACHING_DEF   GEN/KILL def→use data dependence (pure solver)   (M2 #2082)
-L5  CDG            Ferrante control dependence (post-dominators)    (M5 #2085)
-```
-
-All three are `BasicBlock → BasicBlock` edges in the single `CodeRelation` table
-(keyed by the `type` property). There is **no** `Function → BasicBlock` edge.
-
-## The two modes
-
- `pdg_query({ mode: 'controls', target })` — CDG. For the anchored function,
-  each edge: controlling predicate block → dependent block + branch sense in
-  `label` (`'T'` = predicate's true/taken arm, `'F'` = false/fall-through). An
-  edge into an early-return/throw block is flagged `guard: true`.
- `pdg_query({ mode: 'flows', target, variable? })` — REACHING_DEF def→use
-  edges; `variable` filters to one binding.
-
-`target` is **required** — a file path or a symbol/function name (resolved like
-`context()`). There is no anchorless mode (see below).
-
-## The corrected guard-clause Cypher
-
-The RFC #567 §2 form (`[:CDG {label:'F'}]`) does **not** run as written. Edges
-are values of the single `CodeRelation` table's `type` property, and the branch
-sense is in `reason`, NOT a `label` column:
-
-```cypher
-MATCH (pred:BasicBlock)-[r:CodeRelation {type: 'CDG'}]->(dep:BasicBlock)
-WHERE dep.text STARTS WITH 'return' OR dep.text STARTS WITH 'throw'
-RETURN pred.startLine, r.reason AS branch, dep.startLine, dep.text
-```
-
-`r.reason` is the sense the predicate took to reach the early exit. For
-`if (!ok) return;` the return rides the predicate's **true** arm (`'T'`) and the
-protected body rides the **false** arm (`'F'`) — polarity depends on the guard,
-so don't hard-code one sense.
-
-## Gotchas (the load-bearing ones)
-
- **Always anchored + LIMIT-bounded.** LadybugDB has no rel-property index, so
-  an unanchored `[:CDG*]`/`[:REACHING_DEF*]` path scan is unbounded. `pdg_query`
-  requires `target` and bounds the page; raw `cypher` callers must anchor on a
-  file id-prefix or symbol span themselves.
- **BasicBlock↔symbol join is reconstructed.** No `Function→BasicBlock` edge:
-  the block is matched by its id-prefix (`BasicBlock:<file>:<fnStartLine>:…`)
-  plus `startLine` within the symbol's span. BasicBlock `startLine` is **1-based**
-  while the symbol node's `startLine`/`endLine` are **0-based**, so **both** bounds
-  are shifted `+1` (`[symStart+1, symEnd+1]`): the upper `+1` keeps a guard/def/use
-  on the function's **final line**, the lower `+1` excludes an adjacent function's
-  block on the line directly **above**. Same-line / nested functions anchor coarsely.
- **No PDG layer ⇒ a note, not an error.** If the repo wasn't indexed with
-  `--pdg` the tool returns `{ results: [], note: "no PDG layer …" }` (cheap meta
-  probe on `RepoMeta.pdg.maxCdgEdgesPerFunction` / `maxReachingDefEdgesPerFunction`).
- **CDG labels are binary in M5/M6.** Every `switch`-case arm is `'T'`; per-case
-  conditions are not yet distinguished.
- **Intra-procedural only.** Cross-function flow is taint's domain (`explain`).
-
-## Mirror, don't fork
-
-`_pdgQueryImpl` is the front half of `_explainImpl` (WAL wrapper, meta no-layer
-probe, limit validation, `resolveSymbolCandidates` anchoring) with CDG/
-REACHING_DEF instead of TAINTED — and none of taint's path-codec / interproc
-`TAINT_PATH` machinery. Reuse those shared helpers; do not re-implement them.

-# CFG & Taint Analysis with GitNexus
-
-Expert knowledge for the opt-in `--pdg` program-analysis subsystem: control-flow
-graphs, reaching definitions, and intra- + inter-procedural taint. Read this
-before touching `gitnexus/src/core/ingestion/cfg/**` or
-`gitnexus/src/core/ingestion/taint/**`, or when explaining a finding.
-
-## When to Use
-
- "How does the taint engine work / why is this flow (not) reported?"
- Adding a source, sink, or sanitizer to the model.
- Extending or reviewing the CFG / reaching-defs / taint / summary code.
- Understanding the `explain` MCP tool's findings (intra- vs inter-procedural).
- Debugging a false positive or false negative in `--pdg` output.
-
-## The layered substrate (build order)
-
-Taint runs **on** the graph, not beside it. Each layer is opt-in behind `--pdg`
-and a default `analyze` run is **byte-identical** (the golden parity gate is the
-hard floor for every change here).
-
-```
-L1  CFG            per-function basic blocks + control-flow edges   (M1 #2081)
-L2  REACHING_DEF   GEN/KILL def→use data dependence (pure solver)   (M2 #2082)
-L3  Taint (intra)  source→sink over RD facts, minus sanitizers      (M3 #2083)
-L4  Taint (inter)  per-function summaries composed over CALLS       (M4 #2084)
-```
-
- **Worker-built, main-thread-solved.** The parse worker builds each function's
-  CFG + harvests def/use + call-site facts onto `ParsedFile.cfgSideChannel`
-  (plain, structured-clone-safe data — never AST nodes). The main thread runs
-  the pure solvers. NEVER re-parse on the main thread (re-introduces the #1983
-  OOM).
- **In-phase emit (KTD1).** L1–L4-harvest all run INSIDE the scope-resolution
-  pdg window (`scope-resolution/pipeline/run.ts`, gated `input.pdg === true`),
-  because the disk-backed ParsedFile store is cleared when that phase ends — a
-  standalone post-`mro` phase would read empty data. The cross-function fixpoint
-  (L4) is the exception: it runs in its OWN registered phase (`taintSummaries`)
-  AFTER scope-resolution, because it needs the COMPLETE call graph, and consumes
-  small plain summary data threaded out via `ScopeResolutionOutput`.
- **Pure-solver contract.** `computeReachingDefs`, `computeTaintFlows`,
-  `harvestFunctionSummary`, and `solveInterprocTaint` are pure and deterministic
-  (no graph, no I/O, no logger; sorted outputs). Snapshot tests and
-  content-derived edge ids depend on it.
-
-## Intra-procedural taint (L3)
-
-Forward reachability over RD facts from matched **sources** to matched **sinks**,
-killed by **sanitizers**. Key design points worth internalizing:
-
- **Occurrence-tagged sites.** A flat per-arg binding set cannot tell
-  `exec(escape(x))` (safe) from `exec(x)` (finding); the harvest records nested
-  call structure (`SiteRecord.parent`/via-tags) so sanitizer interposition is
-  precise.
- **Kind-set sanitizer model.** A taint carries a set of *neutralized*
-  `SinkKind`s; a sink fires unless its kind is in the set. So `escape(req.body)`
-  suppresses `res.send` (xss) but STILL fires `db.query` (sql) — a kind-blind
-  kill would be a suppressed live injection (the forbidden FN direction).
-  `path.basename(t)` neutralizes path-traversal only, not command-injection.
- **Statement-level finding identity.** NOT block-pair (block conflation drops
-  distinct findings; `exec(req.body, req.query)` is two findings).
- Persisted as `TAINTED` edges (BasicBlock→BasicBlock); the path rides the
-  `reason` column via the shared versioned codec (`taint/path-codec.ts`).
-
-## Interprocedural taint (L4) — the functional/summary method
-
-The production approach (Sharir-Pnueli 1981; the same shape as Meta's Pysa and
-Mariana Trench, and FB Infer) — NOT full IFDS tabulation. Each function is
-reduced to a compact **summary**, and summaries are composed over the already-
-resolved `CALLS` graph.
-
-**Summary shape** (`taint/summary-model.ts`, whole-parameter granularity):
-
-| Edge | Meaning | Analogue |
-|------|---------|----------|
-| `param→return` | a param flows to the return value | TITO — **reserved** (the floor already covers its recall; precision pass deferred) |
-| `param→callee-arg` | a param flows into arg *j* of a call (carries the path's neutralized sink kinds) | TITO into callee |
-| `param→sink` | a param reaches a modelled sink | partial/triggered sink |
-| `source→return` | the function generates+returns a source | generative — **composed** via the caller's `callResults` |
-| `source→callee-arg` | a generated source flows into a call | fixpoint SEED |
-| `callResults` | a user-function call's result flows to a sink/return/callee-arg in the caller | composes with callee `source→return` |
-
-**The fixpoint** (`taint/interproc-solver.ts`): the unit is `(function,
-parameter, source)`. Seed from `source→callee-arg`, propagate via
-`param→callee-arg`, fire a finding when a tainted param meets `param→sink`.
-
- **Cycle-safe by monotonicity.** The tainted-set is monotone over a finite
-  lattice (`fn × param × source`), so the worklist converges — a recursive call
-  just re-proposes an already-visited entry. SCC condensation would only refine
-  processing order; correctness/termination don't require it.
- **Source-discriminated state (load-bearing).** Key the state by the SOURCE
-  too. Keying only by `(fn, param)` collapses multi-source flows: a sink param
-  tainted by source A is marked visited and a later flow from source B is dropped
-  before firing — the recurring multi-source bug class. (Bit M3; bit M4 U9.)
- **Name-based call join.** Match a summary's call-arg edge to a `CALLS` edge by
-  CALLEE NAME, not call-site line — line-base parity (CFG 1-based vs reference
-  site) is fragile; the callee identity is exact and context-insensitivity
-  taints the callee's param identically at every call site.
- Persisted as `TAINT_PATH` edges (Function→Function), function-level hop chain
-  in `reason` via the same codec; confidence < the intra-procedural 1.0.
-
-**Context-insensitivity** is the accepted trade-off at this tier: one summary
-per function, return/call-site merging accepted (security-conservative). Expect
-some FP from merging; the bigger FN sources are unmodeled features (below).
-
-## Known false-negative classes (documented, deferred)
-
-The largest is **closures/callbacks** (`arr.forEach(() => sink(y))`) — taint
-into a callback is dropped without per-library models (true of CodeQL's JS libs
-too). Also deferred: field/property flows (`obj.x = taint; sink(obj.y)`),
-field-sensitive access paths, guard-style sanitizers, implicit/control-dependence
-flows, promise/async-await threading, and **destructured/rest params before a
-tainted simple param** (the summary port index is the binding ordinal, not the
-formal arg position — needs a formal-param index threaded from the worker
-`BindingEntry`). The interprocedural join is also context-insensitive: when one
-caller invokes two distinct **same-named callees**, a flow into one
-over-attributes to both (sound — over-report, never a missed flow). Absence of a
-finding is NOT proof of safety.
-
-## GitNexus-specific gotchas
-
- **Function↔CFG join.** `FunctionCfg.functionStartLine` is 1-based; `Function`/
-  `Method` node `startLine` is 0-based — join at `startLine - 1`. Function nodes
-  have no column, so same-line functions (`{a:()=>x(), b:()=>y()}`) are
-  ambiguous → drop (the summary driver counts `unresolved`) rather than
-  cross-wire.
- **No rel-property index (S1).** Kuzu has no secondary index on relationship
-  properties, and unanchored `[:TAINTED*]`/`[:TAINT_PATH*]` queries explode.
-  TAINT_PATH is therefore MATERIALIZED + anchored at analyze time, never
-  traversed live; `explain` reads it source-anchored + LIMIT-guarded.
- **`explain` is the only discovery surface.** `TAINTED`/`TAINT_PATH` are
-  deliberately OUT of `VALID_RELATION_TYPES` (impact's allow-list) and the web
-  schema (pinned in `security.test.ts`). `explain` enumerates both layers
-  (cross-function findings carry `interprocedural: true`).
- **One shared codec.** Both the emit path and `explain` import
-  `taint/path-codec.ts`. Two hand-rolled copies of a wire format drift — never
-  fork it. New metadata extends the format WITHIN the version when writer +
-  reader ship together.
- **Cache versioning.** A worker-harvest shape change bumps the parse-cache pdg
-  NAMESPACE (`pdg:N`), NOT `SCHEMA_BUMP` (which cold-invalidates every user).
-  Persisted-graph/config changes ride `RepoMeta.pdg`'s key-union mismatch →
-  full writeback. Model content rides `taintModelVersion`.
-
-## Adding a source / sink / sanitizer
-
-Edit the language model in `taint/typescript-model.ts` (registered via the
-explicit `registerBuiltinTaintModels` seam, keyed by `SupportedLanguages`). The
-spec is hashable data (no functions). A sanitizer's `neutralizes` lists the
-EXACT sink kinds it defends — never a blanket kill. Add a fixture + assert the
-finding (or its absence) in `test/unit/taint/` (real-source harness:
-`test/helpers/ts-cfg-harness.ts`); the end-to-end proof is
-`test/integration/cfg/`.
-
-## Validation checklist for any `--pdg` change
-
-```
-1. tsc clean (schema additions are exhaustiveness-checked; watch the
-   api.ts getNodeQuery runtime read-path if a node label is added).
-2. Targeted vitest by directory (test/unit/taint, test/unit/cfg,
-   test/integration/cfg) — verify by ISOLATION, not full-suite exit
-   (known load-flakes). `node scripts/build.js` before worker/integration runs.
-3. Flag-off golden byte-identical (pipeline-graph-golden.test.ts).
-4. bench/cfg/measure.mjs --check (no fingerprint drift / budget regression).
-5. detect_changes() before commit; impact({direction:'upstream'}) before
-   editing shared symbols (KnowledgeGraph, RepoMeta, RelationshipType, codec).
-```
-
-## Prior art (for deeper design questions)
-
-Sharir & Pnueli 1981 (functional approach); Reps-Horwitz-Sagiv IFDS (POPL 1995);
-FlowDroid/StubDroid (access-path summaries); Pysa & Mariana Trench (TITO /
-propagations, parallel SCC fixpoint); CodeQL Models-as-Data (the richest port
-notation, incl. callback ports); Infer (content-keyed incremental summaries).

-
-A cross-platform Dev Container that pre-installs Claude Code, OpenAI Codex CLI, Cursor CLI, and Bun alongside the GitNexus native build chain. Supported hosts: **macOS, Linux, Windows 11 (native), and Windows 11 via WSL2.** Windows-native needs a **one-time `HOME` env var setup** — handled automatically by the `initializeCommand` on first run (see [Windows 11 setup](#windows-11-setup)).
-
-> ### ⚠️ Read this before using it on a work machine
->
-> This devcontainer **does not write to your host AI-CLI config.** Your skills, agents, commands, plugins, memory, prompts, and rules are **copied once** from a read-only host stage into a per-container volume on first create; the container edits its own copy and can never write back. So a compromised workspace dependency running in the container **cannot** drop a malicious agent, command, skill, or plugin onto your host for your next host CLI session to load — the write-through vector earlier versions had is closed. Your **credentials** (Claude/Codex/Cursor logins, plus `gh`) likewise stay in per-container volumes and are never written back, and `~/.ssh`, `~/.aws`, `~/.azure`, and `~/.docker` are mounted **read-only**.
->
-> What is **still** exposed: the read-only host stages (`/host/.claude`, `/host/.codex`, `/host/.cursor`, `/host/.claude-mem`) and the read-only credential mounts are all **readable** inside the container. A compromised dependency can therefore READ your host CLI config, memory, SSH/cloud credentials, and GitHub token — and there is **no egress firewall yet**, so it has the network to exfiltrate what it reads. Read-only protects you from tampering and write-back, not from disclosure.
->
-> The trade-off of the copy model: host and container config **diverge after first create.** A skill or plugin you add on the host later won't appear in the container until you wipe the config volume and rebuild (see [§ Rebuild / reset](#rebuild--reset)). Edits you make inside the container persist across rebuilds but never reach the host.

-
-## Quick start
-
-1. Install [Docker Desktop](https://docs.docker.com/desktop/) (Windows/macOS) or Docker Engine (Linux).
-2. Install [VS Code](https://code.visualstudio.com/) with the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers).
-3. Install [Node.js](https://nodejs.org/) on the **host** (Node 18+). This is the only host-side toolchain dependency beyond Docker and VS Code — the devcontainer's `initializeCommand` runs `node .devcontainer/ensure-host-config-dirs.cjs` to set up the bind-mount source directories before container create. If you already use Claude Code or another Node-based CLI on the host, you're already set.
-4. Open the repo in VS Code → Command Palette → **Dev Containers: Reopen in Container**.
-5. Wait for the first build (~3–6 minutes) and `postCreateCommand` to finish installing workspace dependencies.
-6. Authenticate the three CLIs once — see [First-time CLI authentication](#first-time-cli-authentication) below.
-
-## Windows 11 setup
-
-### Windows-native (one-time setup, then "just works")
-
-The host bind mounts use `${localEnv:HOME}/.claude` (and `.codex`, `.cursor`, `.ssh`, `.config/git`, `.config/gh`, `.gitconfig`). VS Code resolves `${localEnv:HOME}` by reading its own process env, and Windows doesn't set `HOME` by default — it uses `USERPROFILE`. So the bind mounts can't resolve until you tell Windows to also expose your profile as `HOME`.
-
-The `initializeCommand` (`node .devcontainer/ensure-host-config-dirs.cjs`) handles this automatically:
-
-1. **First time you Reopen in Container**, the script detects the missing `HOME`, runs `setx HOME "%USERPROFILE%"` (which writes to your user-level Windows env — no admin needed), prints a one-time setup banner, and exits.
-2. **Close all VS Code windows** (File → Exit) and reopen. VS Code picks up the new `HOME` at startup.
-3. **Reopen in Container again.** The script now sees `HOME=C:\Users\<you>`, skips the setup block, creates the bind-mount source dirs, and Docker brings the container up.
-
-Subsequent rebuilds work normally with no extra steps. The `HOME` env var is set persistently in your Windows user environment, so it'll be there for every future VS Code session (and any other tool that wants `HOME`).
-
-If you'd rather set it manually before opening the container:
-
-```powershell
-setx HOME "%USERPROFILE%"
-# Close & reopen VS Code
-```
-
-### Known trade-offs of Windows-native vs WSL2
-
-Windows-native works, but Docker Desktop's Windows bind-mount layer has rough edges that WSL2 avoids:
-
- **File watchers can miss events.** Vite / jest `--watch` running inside the container watching workspace files mounted from `D:\...` may miss changes — chokidar polling (`CHOKIDAR_USEPOLLING=true`) is the usual workaround.
- **`npm install` is 3-5× slower** through the Windows-to-Linux bind-mount translation than on a WSL2-native filesystem.
- **Permission edge cases.** The husky `.husky/_/h` EPERM class we hit earlier in this PR is specific to Windows-side bind mounts changing UID ownership between container runs. `post-create.sh` clears the cache defensively to keep this from being fatal, but it's still a real source of friction.
-
-If you hit any of those and want to migrate to WSL2 later, the steps are below.
-
-### WSL2 (faster, fewer edge cases)
-
-To clone and open the repo inside WSL2:
-
-```bash
-# 1. Install WSL2 and a Linux distro if you haven't already.
-wsl --install -d Ubuntu
-
-# 2. Enter WSL.
-wsl
-
-# 3. Clone the repo inside your WSL2 home directory.
-cd ~
-git clone https://github.com/abhigyanpatwari/GitNexus.git
-cd GitNexus
-
-# 4. Launch VS Code from inside WSL — this opens VS Code attached to the WSL2
-#    filesystem, so `${localEnv:HOME}` resolves to the WSL user's home and
-#    subsequent "Reopen in Container" uses the WSL2-side path.
-code .
-```
-
-Then run **Dev Containers: Reopen in Container**. The workspace will be bind-mounted from `\\wsl$\Ubuntu\home\<user>\GitNexus`, which is fast and gives reliable file-system events. **Make sure Docker Desktop's WSL integration is enabled** for your distro: Docker Desktop → Settings → Resources → WSL Integration → toggle on the distro you cloned into.
-
-## macOS
-
-Open the repo folder in VS Code → **Reopen in Container**. The image is multi-arch; on Apple Silicon you'll pull the `linux/arm64` variant automatically.
-
-## Linux
-
-Same as macOS — open in VS Code and reopen in container. `updateRemoteUserUID: true` (default) shifts the container's `node` user UID/GID to match your host user, so bind-mounted files stay writable without extra setup.
-
-## How CLI state flows from your host
-
-### AI CLIs (Claude Code, Codex, Cursor): copy-once from a read-only host stage + per-container credentials
-
-The three AI CLIs use a **copy-from-read-only-stage topology**: the host's `~/.<cli>` folders (and `~/.claude-mem`) are mounted **read-only** at `/host/.<cli>`, and `post-create.sh` copies out of them into per-container named volumes. Credentials, identity, and single config files are copied on **every** create; the shareable subdirs (plugins, skills, agents, memory, commands, prompts, rules) are copied **once** on first create and then owned by the container. Nothing is bind-mounted read-write into the host's CLI config, so the container can never modify your host setup. Session sub-paths overlay the config volume via their own named volumes (Docker mount precedence — more specific path wins).

-
-**What gets seeded once from the host (copy, not bind):**
-
- **Claude**: `plugins/marketplaces`, `plugins/cache`, `skills/`, `agents/`, `memory/`, `commands/`
- **Codex**: `plugins/` (whole dir), `prompts/`, `memories/`, `skills/`
- **Cursor**: `plugins/marketplaces`, `plugins/local`, `rules/`, `commands/`, `agents/`, `skills/`
-
-On the **first** container-create, `post-create.sh` copies each of these out of the read-only `/host/.<cli>` stage into the per-container config volume, then writes a `.devcontainer-shareable-seeded` marker. On every later rebuild the marker is present, so the copy is skipped and the container keeps whatever it has accumulated. A plugin/skill/agent you install **inside** the container persists across rebuilds; one you add on the **host** after first create won't appear in the container until you remove the config volume and rebuild (see [§ Rebuild / reset](#rebuild--reset)). Nothing here is writable back to the host — `/plugin marketplace add` inside the container installs into the container's own volume copy, not your host `~/.<cli>/plugins/`.
-
-**Single config files are copied on container-create, not bind-mounted** — on Docker Desktop Windows a single-file bind is 9p while the named volume is ext4, and atomic config writes (`tmp` → rename onto target) trip EXDEV (this is what caused Codex's `config/batchWrite failed in TUI`). So these are synced from host on rebuild and the container rewrites its own copy until the next rebuild: `settings.json` + `$HOME/.claude.json` (Claude), `config.toml` (Codex), `cli-config.json` + `mcp.json` (Cursor). `hooks.json` (Cursor) is deliberately **not** synced — Cursor hooks execute shell commands, so sharing them would widen the supply-chain attack surface; add it yourself if you want it.
-
-**Plugin registry files with absolute paths are translated, not copied verbatim** — Claude's `known_marketplaces.json` / `installed_plugins.json` / `plugin-catalog-cache.json` and Cursor's `installed_plugins.json` bake in `C:\Users\…` (Windows) or `/Users/…` (macOS) install paths. `post-create.sh` rewrites those to `/home/node/.<cli>/plugins/…` and writes the result into the named volume, so plugins resolve inside Linux instead of failing with `cache-miss`. This translation is **also seed-once per CLI** — it runs only for a CLI being seeded that create (`translate-plugin-registries.cjs claude cursor`), so it stays consistent with the seed-once `cache/` copy and won't overwrite a plugin you installed inside the container on a later rebuild. Codex needs no translation — its enablement registry is `config.toml` (git URLs + logical keys, no filesystem paths), so its whole `plugins/` dir is copied as-is.
-
-**What stays per-container (in the named volume) and is synced from host on container-create:**
-
- `.credentials.json` (Claude OAuth tokens), `auth.json` (Codex), `cli-config.json` (Cursor) — credentials
- `~/.claude/.claude.json` (Claude's identity-only file: `userID`, `oauthAccount`, migration tracking) — kept per-container so logging in via container doesn't overwrite host's stored identity
-
-`post-create.sh` runs on every container-create, copies host's credentials into the volume if present, then container manages refresh from there. Sync is "always overwrite if host has the file, otherwise leave container alone". So:
-
- Host has credentials → container starts logged in.
- Host has no credentials → `claude login` / `codex login --device-auth` / `cursor-agent login` inside container; credentials stay in the named volume across rebuilds (volume is keyed by `${devcontainerId}`, stable for the workspace path).
- `claude logout` inside container clears volume credentials only; host is untouched.
-
-**Why CLAUDE_CONFIG_DIR is intentionally NOT set:** Claude's default `~/.claude` matches the named-volume mount target, so the env var added no behavior — but setting it changed which file Claude reads `hasCompletedOnboarding` from. With it set, Claude reads `$CLAUDE_CONFIG_DIR/.claude.json` (the small identity-only file) and re-onboards every container; without it, Claude reads `$HOME/.claude.json` (copied from the read-only `/host/.claude.json` stage on container-create via `seed-claude-config.cjs`, with `hasCompletedOnboarding: true`).
-
-**Host CLI config is protected from write-through.** The shareable dirs are copied out of a **read-only** stage into the container's own volume, so a compromised npm package in the workspace dep tree — running inside the container — **cannot** write a malicious agent, command, skill, or plugin back to `~/.claude/`, `~/.codex/`, or `~/.cursor/` on the host. The earlier design bind-mounted these read-write and accepted that write-through as the cost of live sync; this design closes it. An even earlier alternative (read-only stage + symlinks) made `/plugin marketplace add` inside the container fail with EROFS; copying into a writable volume avoids that, because the container writes to its own copy rather than a read-only mount. What a compromised dependency can still do is **read** the read-only host stages (`/host/.<cli>`, `/host/.claude-mem`) and the read-only credential mounts and exfiltrate them — there is [no egress firewall yet](#whats-not-included-yet). The cost of the copy model is **divergence**: host edits made after first create don't reach the container until you wipe the config volume and rebuild.
-
-**Refresh-token divergence between rebuilds.** Container's credentials match host's at container-create time; after that, container manages its own refresh until the next rebuild. Anthropic rotates refresh tokens on every use, so an unattended container that hasn't talked to the API in weeks can hit a silent 401 if the host has refreshed since. Re-run `claude login` inside the container, or rebuild, to recover.

-**claude-mem is seeded once, then container-private.** The [claude-mem](https://github.com/thedotmack/claude-mem) store (`$HOME/.claude-mem` — a multi-GB SQLite DB `claude-mem.db` + `-wal`/`-shm`, plus a Chroma vector store `chroma/chroma.sqlite3` and its HNSW index binaries) is the one shareable-looking folder that is **deliberately not a host bind**, for the same SQLite reason as sessions below: a multi-GB WAL database over the 9p/virtiofs bind risks unreliable `fcntl` locking and corruption — sharply so if claude-mem ran on the host and in the container against the same DB at once. So it gets its own per-container named volume (`claude-mem-${devcontainerId}`), and `post-create.sh` **seeds it once** from the read-only `/host/.claude-mem` stage _only when the volume has no DB yet_. The first container-create copies the host's store in (a one-time copy, possibly several GB); every later rebuild keeps whatever the container accumulated and skips the copy. The container's memory and the host's **diverge from that seed point** — writes do not flow back — which is the price of keeping SQLite off a shared bind. To re-seed from the host's current store, remove the volume (`docker volume rm claude-mem-<id>`) and rebuild. `ensure-host-config-dirs.cjs` creates an empty `~/.claude-mem` on hosts that never installed claude-mem, so the read-only stage bind always resolves; the seed then finds no DB and the container simply starts with empty memory.

-### Session resume across container recreation
-
-`claude --resume`, `codex resume`, and `cursor-agent resume` all read **local** transcript files. Those live _inside_ each CLI's config dir, which is a per-container named volume — so they already survive an ordinary **Rebuild Container**. What they did _not_ survive were the very things this README tells you to do: `docker volume rm <cli>-config-${devcontainerId}` to force a re-login or clear an `EACCES`, a `${devcontainerId}` change, or a full delete-and-recreate. Each of those drops the config volume and takes your session history with it.
-
-So the resume/transcript directories get their **own** named volumes (mount group 6 in `devcontainer.json`), keyed like the `node_modules` volumes (`${localWorkspaceFolderBasename}-…-${devcontainerId}`) and mounted _over_ the config volume at the session sub-paths:
-
-| Resume command                   | Persisted volume → target                                                               | What's stored                                                                                                                                                                                                                                          |
-| -------------------------------- | --------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
-| `claude --resume` / `--continue` | `…-claude-sessions-…` → `~/.claude/projects`                                            | `<encoded-cwd>/<uuid>.jsonl` transcripts + `sessions-index.json`. Container cwd is always `/workspace`, so only that slice is stored. Pure JSONL/JSON — no SQLite.                                                                                     |
-| `codex resume` / `resume --last` | `…-codex-sessions-…` → `~/.codex/sessions`                                              | `YYYY/MM/DD/rollout-*.jsonl`. The `state_5.sqlite` thread index stays on the config volume (a single WAL file we don't split out); when it's absent after a recreation, Codex rebuilds it from these rollouts on the next start (a one-time backfill). |
-| `cursor-agent resume` / `ls`     | `…-cursor-sessions-…` → `~/.cursor/chats`; `…-cursor-projects-…` → `~/.cursor/projects` | `chats/{hash}/{uuid}/store.db` (one SQLite db per session, each in its own dir) + `projects/.../agent-transcripts`. cursor-agent's layout is reverse-engineered, so treat this as best-effort.                                                         |
-
-Because these are **separate** volumes from `<cli>-config-${devcontainerId}`, the re-login fix (`docker volume rm claude-config-…`) no longer destroys your sessions — that was the point.
-
-**Survives:** Rebuild Container, Rebuild Without Cache, a full delete-and-recreate of the container, and the `docker volume rm <cli>-config-…` re-login / `EACCES` fix.
-
-**Does _not_ survive** (same durability tier as the `node_modules` volumes): `docker volume prune`, a `${devcontainerId}` change (moving the checkout to a new path, or switching between Windows-native and WSL2), or moving to a new machine. To deliberately wipe sessions, remove the session volumes too — see [Rebuild / reset](#rebuild--reset). Two checkouts with the **same folder name** on one host would share session volumes only if they also share a `${devcontainerId}`; they don't, so they stay separate.
-
-**First rebuild after adopting this, one-time:** if a container created _before_ these volumes existed already had sessions on the config volume (`~/.claude/projects`, `~/.codex/sessions`, …), the new empty session volume mounts _over_ that sub-path and **masks** the old content — same Docker-precedence shadowing described for plugins above. The old sessions are hidden, not deleted. To carry them forward once, copy them out of the config volume into the session volume; or just start fresh — new sessions land on the session volume from then on.
-
-**Why sessions are container-private and not even seeded from the host.** The shareable config dirs are _seeded once_ from the host (you want your skills/agents/plugins in the container). Sessions are deliberately _not_ seeded and never touch the host, because a transcript can contain anything you pasted or the agent read — API keys, file contents, connection strings. Binding or copying them to/from the host would (a) spill that to host disk, (b) add a write-through surface a compromised dependency can reach (there's still [no egress firewall](#whats-not-included-yet)), and (c) leak _every other project's_ transcripts into the container (Codex `sessions/` and Cursor `chats/` aren't project-scoped). Container-private volumes avoid all three while still surviving recreation. And Claude/Codex transcripts embed the container cwd (`/workspace`), so even if you _did_ bind them to the host, the host CLI wouldn't natively `--resume` them — its encoded-cwd folder differs.
-
-**Opt in to host-shared sessions anyway.** If you want transcripts visible/portable on the host and accept the trade-offs above, uncomment the host-bind block in `devcontainer.json` (just below the group-6 volumes) and add the matching source dirs to `ensure-host-config-dirs.cjs`'s `DIRS` so Docker can resolve the binds. That block scopes Claude to `/workspace`'s encoded subdir to limit the cross-project leak; the Codex and Cursor stores can't be scoped that way, so they expose every project's transcripts.

-### Other host bind mounts
-
-| Container path  | Host source         | Mode          | Why                                                                                    |
-| --------------- | ------------------- | ------------- | -------------------------------------------------------------------------------------- |
-| `~/.config/git` | `$HOME/.config/git` | **read-only** | XDG-style git config / ignore / attributes                                             |
-| `~/.ssh`        | `$HOME/.ssh`        | **read-only** | SSH commit signing + git push over SSH                                                 |
-| `~/.config/gh`  | `$HOME/.config/gh`  | **copy → volume** | `gh` CLI auth (PR/issue create, checks) — seeded from your host login on create into a per-container volume; in-container `gh auth login` persists across rebuilds and never writes back to the host |
-| `~/.docker`     | `$HOME/.docker`     | **read-only** | Container registry auth + buildx config (inert until you add Docker CLI via a Feature) |
-| `~/.aws`        | `$HOME/.aws`        | **read-only** | AWS CLI / SDK credentials (forward-compat — empty by default)                          |
-| `~/.azure`      | `$HOME/.azure`      | **read-only** | Azure CLI credentials (forward-compat — empty by default)                              |
-
-**Why `ssh`/`aws`/`azure`/`docker` are read-only, and why `gh` is copied into a volume:** `ssh`/`aws`/`azure` are consumed read-only by their clients (the SSH client and the AWS/Azure SDKs only read their credential files), so a one-way mount loses nothing. `docker` _can_ write its own state (`docker login` / buildx write `config.json`), but a read-write host bind would let a compromised in-container dependency rewrite your host `~/.docker/config.json` (point a `credHelper` at an attacker-controlled binary) — a credential-takeover vector. The common case is _reading_ an existing host login, so `docker` stays **read-only**: registry pulls/pushes using your host creds work, only a `docker login` inside the container won't persist back. `gh` used to be read-only for the same reason, but that meant an in-container `gh auth login` had nowhere to write and silently failed. So `gh` now uses the **copy-into-volume** model (the same one the AI-CLI credentials use): the host `~/.config/gh` is a read-only _stage_ at `/host/.config/gh`, and `post-create.sh` copies `hosts.yml`/`config.yml` out of it into the per-container `gh-config` volume on create. The container gets a **writable** copy — `gh auth login` / `gh auth refresh` inside the container now work and persist across rebuilds — while the read-only stage guarantees nothing is ever written back to the host's token. If you want `docker` to behave the same way, give it the same treatment (a `/host/.docker` stage + a docker-config volume + a copy step in `post-create.sh`).
-
-`~/.gitconfig` is **not** bind-mounted — VS Code's Dev Containers extension auto-copies the host's gitconfig into the container at attach time (this is built-in behavior, not something this devcontainer configures). The bind-mount approach conflicts with that auto-copy mechanism, so we let VS Code own it. The end result is the same: your host's `user.name` / `user.email` are available inside the container.
-
-If a host source dir doesn't exist when the container is first created, the `initializeCommand` (`node .devcontainer/ensure-host-config-dirs.cjs`) creates it empty — so the bind mount always has a valid source.
-
-### Per-CLI quirks worth knowing
-
- **Claude Code on macOS** stores credentials in the system Keychain, not in `~/.claude/.credentials.json`. The sync silently no-ops; run `claude login` inside the container once and the named volume persists it.
- **Codex on macOS / Linux with `cli_auth_credentials_store = "keyring"`** stores auth in the OS keyring (Keychain / Secret Service), so `~/.codex/auth.json` may not exist on host. Same fallback: `codex login --device-auth` inside the container.
- **Cursor CLI inside containers** has [known upstream auth issues](https://forum.cursor.com/t/cursor-agent-authentication-issue-inside-docker/143995) — even with a correctly-synced `cli-config.json`, you may need to re-run `cursor-agent login` inside the container.
- **Stale named volumes from old rebuilds can carry forward.** If you delete and re-create the same workspace, or if a prior container left interim state with a different `userID`, deleting the named volumes before rebuild guarantees a clean sync: `docker volume rm claude-config-${devcontainerId} codex-config-${devcontainerId} cursor-config-${devcontainerId}` (look them up with `docker volume ls | grep -config-`).
- **User-scope MCP servers with absolute host paths won't resolve in-container.** `~/.claude.json` (Claude), `~/.codex/config.toml` (Codex), and `~/.cursor/mcp.json` (Cursor) are copied from host on container-create, so their user-scope `mcpServers` entries come along. But an entry whose `command` is an absolute host path (`C:\tools\foo.exe`, `/usr/local/bin/foo`) points at a binary that doesn't exist in the container — that server silently fails to launch. Only registry/`npx`-based servers (like this repo's `.mcp.json`, which uses `npx -y gitnexus@latest mcp`) and remote/URL servers work unchanged. The path-translation pass only rewrites `*/.<cli>/plugins/*` registry paths, **not** arbitrary `mcpServers` command paths (there's no correct container target for a host-local binary). Install such MCP servers inside the container, or use `npx`/remote ones.
- **Host config is seeded once per devcontainer, then diverges — this now applies to everything.** A `mcpServers` entry, setting, plugin, skill, agent, or command you add **on the host after** the container was created is not visible in the container until you remove the config volume and rebuild. Single config files (`mcpServers`, `settings.json`, …) are copy-on-create; the shareable dirs (plugins/skills/agents/memory/commands/prompts/rules) are copy-on-**first**-create (they persist across ordinary rebuilds and aren't even re-copied). Both diverge from the host after their copy. To pull host-side changes in, wipe the relevant volume and rebuild (see [§ Rebuild / reset](#rebuild--reset)).
- **Plugins/skills/agents installed in-container persist; they do not reach the host.** A `/plugin marketplace add` (or `codex plugin add`, or a new skill/agent) inside the container writes to the container's own config volume and survives ordinary rebuilds. It never appears on the host — the host dirs are read-only sources, not bind targets. To get a plugin onto the host, install it on the host (then wipe + rebuild to seed it into the container).
- **No cross-checkout plugin contention.** Because each container copies plugins into its own per-`${devcontainerId}` volume rather than sharing one host bind source, two containers (or checkouts) installing plugins at the same time no longer interleave git clones/extractions against a shared host dir. Each writes only its own copy.
-
-### What you still don't have inside the container
-
-These are commonly-needed CLIs that aren't installed by default — adding them would be follow-up work, not in this PR's scope:
-
- **Docker CLI** (for `docker push` / `docker build` from inside the container). Add via `ghcr.io/devcontainers/features/docker-outside-of-docker:1` to the `features` block — `~/.docker/` is already mounted **read-only**, so your host `docker login` state works immediately for pulls/pushes; an in-container `docker login` won't persist to the host (drop `,readonly` on that mount if you need it to).
- **AWS CLI / Azure CLI / gcloud / kubectl** — same pattern: add the matching Feature, the host config dirs already flow through.
- **Private npm registry auth** (`~/.npmrc`) — you don't have a global one on this host. If you ever start using private packages, add `source=${localEnv:HOME}/.npmrc,target=/home/node/.npmrc,type=bind,readonly` to the mounts.
-
-That means:
-
- **Authentication is shared.** If you're already logged in on the host (`claude login`, `codex login`, `cursor-agent login`, `gh auth login`), you're already logged in inside the container. No second login step.
- **Plugins, skills, agents, memory, and commands are seeded from the host once, then container-private.** On first create the container copies your host's plugins/skills/agents/memory/commands (and Codex prompts/memories, Cursor rules) into its own volume. After that they're independent: install or edit inside the container and it stays in the container (persists across rebuilds); add a plugin or agent on the host and the container won't see it until you wipe the config volume and rebuild. Nothing the container does reaches the host. (`settings.json` and the user-scope `~/.claude.json` are copy-on-create the same way; `~/.claude/projects/` is container-local by design.)
- **Git identity comes from the host.** Commits from inside the container use your host's `user.name` / `user.email` — VS Code's Dev Containers extension auto-copies your `~/.gitconfig` into the container at attach time. Any XDG-style config under `~/.config/git/` flows through via the read-only bind mount. To change git identity, edit `~/.gitconfig` on the host (container-side `git config --global` writes to a container-local file that's discarded on rebuild).
- **SSH keys flow through (read-only).** Push over SSH remotes and SSH commit signing work inside the container using your host keys. The mount is read-only so container code can't exfiltrate or modify private keys — agent-perspective, this means you get git operations but the keys stay vendor-side.
- **`gh` auth is shared, and in-container logins persist.** If you're logged in on the host, `gh pr create`, `gh pr checks`, `gh issue create` work inside the container without re-authenticating. If you're not, run `gh auth login` inside the container once — because `gh` config lives in a writable per-container volume (seeded from the host stage), that login persists across rebuilds and never touches the host's token.
- **No per-workspace duplication.** All your devcontainers across all your projects see the same host CLI state, just like all your host shells do.
-
-The bind mount source directories are guaranteed to exist by the `initializeCommand` (`node .devcontainer/ensure-host-config-dirs.cjs`), which runs on the host before container create. It's a Node script (not a shell one-liner) so the same command works on Windows `cmd.exe` and POSIX shells. It creates the top-level bind-mount source dirs — `~/.claude`, `~/.codex`, `~/.cursor`, `~/.claude-mem`, plus `~/.ssh`, `~/.docker`, `~/.aws`, `~/.azure`, `~/.config/{gh,git}`. It deliberately does **not** pre-create the shareable subdirs (skills/agents/plugins/…): those are no longer bind sources (they're copied out of the whole-`~/.<cli>` read-only stage), and pre-creating empty ones would needlessly write into the host of someone who never used that CLI.
-
-### Trust boundary, concretely
-
-Host and container share a single trust boundary by design — fine for personal-dev, but the consequence is concrete. Any malicious npm package or `postinstall` script in the workspace dep tree, running inside the container, has direct **read** access to:
-
- **Host AI CLI state** — the read-only stage at `/host/.claude`, `/host/.codex`, `/host/.cursor`, `/host/.claude-mem`, which exposes your **entire** host `~/.<cli>` tree (credentials, identity, AND the shareable skills/agents/plugins/memory/commands) for _reading_. The container copies what it needs out of this stage; a compromised dep can read all of it. It is read-only, so none of it can be written back
- The **container's own credential snapshots** at `/home/node/.claude/.credentials.json` etc. (copied from host on container-create)
- `~/.claude/memory/` / per-project memory (which may contain user-stored secrets if you've used the `/remember` skill)
- The **current container's own session transcripts** (`~/.claude/projects`, `~/.codex/sessions`, `~/.cursor/chats`/`projects` — the group-6 volumes), which can hold anything pasted into or read during a session. These are container-private (see one-way note below), so this is read access to _this_ container's sessions only, not the host's or other projects'
- Your **`gh` token** (`~/.config/gh`)
- Your **SSH private keys** (`~/.ssh/`)
- Docker registry tokens in **`~/.docker/config.json`** (if you've `docker login`-ed)
- AWS/Azure CLI credentials if you've populated `~/.aws/` or `~/.azure/`
-
-It does **not** have write-through to the host's CLI config. The shareable dirs are copied out of the read-only stage into the container's own volume, so a compromised in-container dep **cannot** write into your host `~/.claude/{plugins,agents,skills,commands,memory}/`, `~/.codex/{plugins,prompts,memories,skills}/`, or `~/.cursor/{plugins,rules,commands,agents,skills}/`. The persistence vector earlier versions had — drop a malicious auto-loaded agent/command/skill/rule onto the host, have it run in your next **host** session — is closed: there is no writable path from the container to those host folders. (Cursor's `hooks.json` is still additionally withheld from even the _container's_ copy, because hooks fire without an agent invoking them.) The boundary is now one-way for **all** of the host CLI config, not just credentials.
-
-**What stays one-way (genuinely protected):** everything. Credentials never flow back to host — `.credentials.json` / `auth.json` / `cli-config.json` live only in the per-container named volumes, and the `/host/.<cli>` stage they're copied from is mounted **read-only**, so the snapshot can't be overwritten back. The shareable AI-CLI dirs (skills/agents/plugins/memory/commands/prompts/rules) are now copy-on-create from that same read-only stage, so they have the one-way property too — readable for the copy, never writable back. `~/.ssh`, `~/.config/git`, `~/.aws`, `~/.azure`, and **`~/.docker`** are read-only binds with the same property — a compromised dep can _read_ your registry tokens but cannot _rewrite_ them to hijack your future host auth. **`~/.config/gh`** is now a read-only _stage_ copied into a per-container volume, so it keeps that same one-way property: the container reads it once to seed its own writable copy, and the read-only stage means an in-container `gh auth login` can never overwrite your host token. **Session transcripts** live in per-workspace named volumes (mount group 6) and are never seeded from or written back to the host, and the container can't see any _other_ project's transcripts. The opt-in host-bind block in `devcontainer.json` reverses that for sessions only — enable it only if you accept transcripts on host disk; see [Session resume across container recreation](#session-resume-across-container-recreation).
-
-**The egress firewall is the key compensating control that is still missing.** It's deferred (see "What's not included (yet)" below), so a compromised package currently has unrestricted outbound network to exfiltrate anything in the read list above. Until it lands, treat that read surface as exposed to any code you run in the container — don't use this devcontainer on a machine whose host credentials you couldn't afford to rotate. The isolated-volume setup below removes host AI-CLI config/credentials from that surface entirely.
-
-**If a workspace dep is ever found compromised**, rotate credentials at the vendor side — local file deletion is insufficient because tokens may have already left:
-
- Anthropic: [console.anthropic.com → Settings → Keys](https://console.anthropic.com/settings/keys), revoke the OAuth session under Account
- OpenAI / Codex: [platform.openai.com/api-keys](https://platform.openai.com/api-keys), revoke session under Profile
- Cursor: dashboard → Integrations, rotate API key + revoke CLI session
- GitHub: `gh auth refresh` or revoke the token at github.com/settings/tokens
-
-For high-trust enterprise environments where the container should not even be able to **read** host CLI state, remove the three read-only stage binds (`/host/.claude`, `/host/.codex`, `/host/.cursor`) — plus `/host/.claude-mem` and `/host/.claude.json` — from `.devcontainer/devcontainer.json`. With no stage to copy from, `post-create.sh`'s seed and credential-sync steps quietly do nothing (their `[ -f ]` / `[ -d ]` guards), and each devcontainer starts with empty, fully isolated config and credentials (Anthropic's reference pattern). You give up seeding your host setup into the container in exchange for removing host config/credentials from the container's read surface entirely; log in inside each container instead.
-
-## First-time CLI authentication
-
-Each CLI works either way:
-
- **Log in on host first** → the container picks it up automatically on the next rebuild (`sync_from_host` copies the credential file into the named volume during `post-create.sh`). Host stays the source of truth.
- **Log in inside the container** → credentials write to the named volume. They persist across ordinary rebuilds (volume is keyed by `${devcontainerId}`, which is stable for a given workspace folder). The host's credentials are untouched.
-
-You can mix and match per-CLI. A common setup is "Claude logged in on host, Codex/Cursor logged in inside container".
-
-### Claude Code
-
-```bash
-claude login
-```
-
-Opens a browser auth flow. VS Code's port forwarding handles the OAuth callback automatically. After auth, `~/.claude/` is populated and visible from both host and container. The `DISABLE_AUTOUPDATER=1` env var prevents the in-container CLI from auto-updating — rebuild the container to pick up a newer Claude Code.
-
-### OpenAI Codex CLI
-
-```bash
-codex login --device-auth
-```
-
-The device-code flow prints a URL and a one-time code. Visit the URL on your host browser, paste the code, and the CLI authenticates without needing a callback listener — this is the most reliable path inside containers. Credentials land in `~/.codex/auth.json` (shared with host).
-
-`codex login` (browser-callback variant) also works but can be flaky in some headless contexts; prefer `--device-auth`.
-
-### Cursor CLI
-
-```bash
-cursor-agent login
-```
-
-Opens a browser auth flow; VS Code's port forwarding handles the callback. Credentials persist in `~/.cursor/cli-config.json` (shared with host).
-
-Verify any time with `cursor-agent status`.
-
-## Alternative: API key authentication (CI / headless)
-
-For non-interactive use (CI runners, automated scripts), all three CLIs accept API keys via env vars:
-
-| CLI         | Env var             | Where to get the key                          |
-| ----------- | ------------------- | --------------------------------------------- |
-| Claude Code | `ANTHROPIC_API_KEY` | <https://console.anthropic.com/settings/keys> |
-| Codex       | `OPENAI_API_KEY`    | <https://platform.openai.com/api-keys>        |
-| Cursor      | `CURSOR_API_KEY`    | Cursor dashboard → Integrations               |
-
-These env vars are intentionally **not** injected into the container from the host. `${localEnv:VAR}` resolves an unset host variable to an empty string, and some CLIs (Cursor in particular) treat a set-but-empty key as "use this key" rather than "fall back to stored login" — which would silently break the login flow for everyone who hasn't pre-set the host var.
-
-To use an API key inside the container, export it in your terminal session:
-
-```bash
-export ANTHROPIC_API_KEY=sk-ant-...
-# or OPENAI_API_KEY, or CURSOR_API_KEY
-```
-
-For persistence across container shells, carry the export via your VS Code [dotfiles repository](https://code.visualstudio.com/docs/devcontainers/containers#_personalizing-with-dotfile-repositories). VS Code clones the dotfiles repo into the container on attach and runs your install command, so the export lands in `~/.bashrc` / `~/.zshrc` per your own setup — and your API keys stay out of this repo's committed `devcontainer.json`.
-
-A non-empty API key env var takes precedence over stored login credentials for each CLI.

-## Known gotchas
-
- **LadybugDB integration tests may fail in containers** (file-locking, `AGENTS.md` § Testing). Default to `npm run test:unit` inside the container; run integration tests on the host. Tracking issue: documented as a known limitation.
- **Single-writer LadybugDB constraint** (`GUARDRAILS.md` § LadybugDB lock). Don't run `gitnexus analyze` on the host and inside the container against the same `.gitnexus/` directory simultaneously — the second writer will get `database busy`.
- **Native grammar builds add ~30s to first install.** Tree-sitter Dart/Proto/Swift/Kotlin are all vendored uniformly: `node-gyp-build` picks a committed GitNexus-built prebuilt `.node` at install time (no compile), and only falls back to compiling from the vendored source during `postinstall` if no prebuild matches the host (then a toolchain is needed). Set `GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` (in your shell or `remoteEnv`, then rebuild) to skip all four; each loses parsing for the affected language(s), and the install still succeeds.
- **`tree-sitter-kotlin`/`tree-sitter-swift` warnings on install** only appear when no prebuild matches the platform-arch (per `AGENTS.md`); they are non-fatal — parsing for that language is simply unavailable.
- **`.mcp.json` works inside the container**: `npx -y gitnexus@latest mcp` resolves cleanly because npm registry is reachable and the workspace bind mount exposes the same `.mcp.json` the host sees.
- **Husky pre-commit fires inside the container** without extra setup. The root `npm install` (run automatically in `postCreateCommand`) installs the hook via `package.json` `prepare`.
-
-## Rebuild / reset
-
- **Rebuild Container** (Command Palette) — re-runs the Dockerfile build and `postCreateCommand` against the existing named volumes (auth, history, **and sessions** persist).
- **Rebuild Container Without Cache** — fresh image layers, same volumes.
- **To force a re-login / clear an `EACCES`** — remove the per-container _config_ volumes and rebuild. As of the session-volume change this **no longer drops your `--resume` history** (sessions are on separate volumes — see [Session resume](#session-resume-across-container-recreation)):
-  ```bash
-  docker volume ls | grep -- -config-          # the credential / identity volumes
-  docker volume rm claude-config-<id> codex-config-<id> cursor-config-<id> gh-config-<id>
-  ```
-  ⚠️ Since the shareable dirs are now seeded into the config volume (not bind-mounted), wiping `<cli>-config` **also discards any plugin/skill/agent/command you installed _inside_ the container** and re-seeds those dirs from the host on the next rebuild. That is the intended way to pull host-side config changes in, but if you have in-container-only plugins you want to keep, reinstall them after the rebuild (or install them on the host first so the re-seed brings them along).
- **To also wipe session history** (a true clean slate) — remove the session volumes too (`<name>` is your workspace folder name):
-  ```bash
-  docker volume ls | grep -E -- '-(sessions|cursor-projects)-'   # the group-6 volumes
-  docker volume rm <name>-claude-sessions-<id> <name>-codex-sessions-<id> \
-                   <name>-cursor-sessions-<id> <name>-cursor-projects-<id>
-  ```
-  Then rebuild.
- **To re-seed claude-mem from the host** (the container's memory has diverged and you want the host's current store back) — remove the claude-mem volume and rebuild; `post-create.sh` copies the host store in again on the next create:
-  ```bash
-  docker volume rm claude-mem-<id>
-  ```
-
-## Bumping CLI versions
-
-Bump the version pins in `.devcontainer/devcontainer.json` `build.args` and rebuild — all three are real, fail-loud pins. Claude Code installs via `npm install -g @anthropic-ai/claude-code@${CLAUDE_CODE_VERSION}` and Codex via `npm install -g @openai/codex@${CODEX_VERSION}`. **Cursor is pinned too:** bump `CURSOR_VERSION` **and** both `CURSOR_SHA256_X64` / `CURSOR_SHA256_ARM64` together — the Dockerfile downloads the pinned `downloads.cursor.com/lab/<version>/linux/<arch>/agent-cli-package.tar.gz` artifact directly (no remote install script) and fails the build on a sha256 mismatch. Re-hash each arch with `curl -fSL <url> | sha256sum`. To stop Cursor from auto-updating in the running container, don't call `cursor-agent update`.
-
-## What's not included (yet)
-
- **Egress firewall — the most important hardening still outstanding.** The original plan included an opt-in iptables/ipset firewall adapted from Anthropic's reference devcontainer. It was deferred to a follow-up PR — `runArgs` is static in `devcontainer.json`, so toggling NET_ADMIN/NET_RAW capabilities cleanly requires either a separate `devcontainer-firewall.json` profile or an `initializeCommand`-generated overlay. Until it lands, the read surface in [§ Trust boundary](#trust-boundary-concretely) has no network containment — anything readable can be exfiltrated. Track at the project's issue tracker if you need this.
- **Codespaces tuning.** The current config works in Codespaces incidentally (no privileged capabilities, no host-mount assumptions), but isn't actively tested there.
- **Playwright e2e support.** `gitnexus-web`'s `npm run test:e2e` needs Chromium libs that the base image doesn't ship. Use the host for e2e until a Playwright layer is added.

-  //    single config files (always), plus the shareable subfolders (Claude
-  //    plugins/skills/agents/memory/commands; Codex plugins/prompts/memories/
-  //    skills; Cursor plugins/rules/commands/agents/skills) ONCE on first create.
-  //    Everything copied lands in the per-container named volume (role 2). It is
-  //    read-only so a container process can NEVER write back to the host — there
-  //    is no read-write bind into the host's CLI config at all. This protects the
-  //    host's on-disk setup: a compromised in-container dependency cannot drop a
-  //    skill, agent, command, or plugin onto the host for the next host session
-  //    to load. The cost is that host and container DIVERGE after the first
-  //    create — host edits don't reach the container until you wipe the config
-  //    volume and rebuild. See README § "Trust boundary, concretely".
-  //
-  // 2. AI CLI container config — one named volume per devcontainer. CODEX_HOME
-  //    points here. CLAUDE_CONFIG_DIR is left unset on purpose, so it resolves
-  //    to the default ~/.claude, which is this same path. Credentials,
-  //    identity, and single config files (.credentials.json,
-  //    ~/.claude/.claude.json, settings.json, config.toml, cli-config.json,
-  //    mcp.json) live here with correct Linux permissions. They are NOT
-  //    bind-mounted, because single-file binds break on Docker Desktop Windows
-  //    (the EXDEV error — see the SINGLE-FILE note below). Container-managed
-  //    state (sessions, history, caches, IDE locks) stays separate per
-  //    devcontainer. So two GitNexus checkouts on the same host can't corrupt
-  //    each other.
-  //
-  // 3. Other host config — read-only bind mounts for credential and identity
-  //    folders that lack the permission-flattening and onboarding-state
-  //    complications Claude Code has (ssh, aws, azure, git config, plus gh and
-  //    docker). gh and docker are read-only so a compromised dependency can't
-  //    rewrite the GitHub token or the Docker credHelper. See the inline note
-  //    at those mounts. `~/.gitconfig` is not mounted here. VS Code auto-copies
-  //    it separately.
-  //
-  // 4. Per-instance state — scoped by `${devcontainerId}`: shell history and
-  //    the npm cache. These survive rebuilds and stay separate between sibling
-  //    instances.
-  //
-  // 5. Per-workspace-name AND per-instance state — the workspace `node_modules`
-  //    volumes use both `${localWorkspaceFolderBasename}` (so you can spot them
-  //    in `docker volume ls`) and `${devcontainerId}` (so sibling instances of
-  //    the same repo never collide). This keeps tree-sitter native binaries and
-  //    onnxruntime off the workspace bind mount, which is faster on Windows and
-  //    macOS.
-  //
-  // 6. Per-workspace session state — dedicated named volumes for each CLI's
-  //    resume/transcript dirs (Claude projects/, Codex sessions/, Cursor chats/
-  //    + projects/). Same `${localWorkspaceFolderBasename}` + `${devcontainerId}`
-  //    keying as group 5, but SEPARATE volumes from the group-2 config volumes.
-  //    That separation is the point: the `docker volume rm <cli>-config-*`
-  //    re-login / EACCES fix (README § Rebuild/reset) no longer wipes sessions,
-  //    so `claude --resume`, `codex resume`, and `cursor-agent resume` survive a
-  //    rebuild, a full delete-and-recreate, AND that wipe. They overlay the
-  //    config volume at the session sub-paths (Docker precedence: more specific
-  //    path wins). Container-private by design — transcripts can hold pasted
-  //    secrets, and like the group-1 config (read-only stage, copy-once) these
-  //    add NO host write-through surface and leak no other projects' transcripts.
-  //    They do
-  //    NOT survive `docker volume prune`, a `${devcontainerId}` change (moving
-  //    the checkout, WSL vs native), or a new machine — same tier as group 5.
-  //    To make sessions host-visible/portable instead, see the commented
-  //    host-bind block below and README § "Session resume across recreation".
-  "mounts": [
-    // One named volume per container for credentials and identity state. Each
-    // CLI's real `~/.<cli>` config folder lives in a volume. That keeps

-"""Enforce the GitHub Actions concurrency convention.
-
-See CONTRIBUTING.md -> "GitHub Actions — Concurrency Convention" for the rules.
-
-Invoked from .github/workflows/ci-quality.yml. Runs locally too:
-    python3 .github/scripts/check-workflow-concurrency.py .github/workflows
-
-Rules:
-  1. Every entry-point (non-reusable) workflow declares a top-level
-     `concurrency:` block.
-  2. Reusable workflows (on: workflow_call ONLY) do NOT declare one.
-  3. The `concurrency.group` expression MUST reference either
-     `${{ github.workflow }}` or one of the approved hardcoded literal prefixes
-     for workflows that are simultaneously entry-points AND reusable (on: push/
-     workflow_call). Two such exceptions are currently approved:
-       - `CI-` for ci.yml (the original canonical form)
-       - `docker-build-push-` for docker.yml
-     This is checked by substring containment rather than prefix match because
-     the group value is a conditional expression that resolves to a `CI-…` or
-     `docker-build-push-…` literal at runtime.
-
-We deliberately do not use a YAML library — keeps the script dependency-free
-on any vanilla runner. `on:` block parsing is line-based and handles both the
-flat (`on: workflow_call`) and mapping (`on:\n  workflow_call:`) forms.

- * Vendored tree-sitter grammar update monitor.
- *
- * Checks each vendored grammar against its upstream source-of-origin and, for an
- * available AND ABI-compatible update, re-vendors the grammar source in place so
- * a PR can be opened. The version bump in vendor/<name>/package.json then triggers
- * .github/workflows/build-tree-sitter-prebuilds.yml, which cross-builds + ABI-
- * validates the prebuilds — so even an imperfect re-vendor can never silently
- * ship: its PR's CI goes red.
- *
- * ABI awareness is load-bearing. Every grammar is pinned to tree-sitter@0.21.1
- * (LANGUAGE_VERSION 13–14, the #1922 gate). Most upstream grammar releases target
- * a newer tree-sitter, so a blind "bump to latest" would pull an ABI-incompatible
- * parser and open doomed PRs. This monitor fetches the candidate source, reads its
- * parser.c `#define LANGUAGE_VERSION`, and only re-vendors when it is 13 or 14;
- * incompatible updates are reported (and surfaced as a workflow notice), not
- * applied.
- *
- * Usage:
- *   node update-vendored-grammars.mjs            # detect only → JSON report on stdout
- *   node update-vendored-grammars.mjs --apply X  # re-vendor grammar X in place
- *
- * tree-sitter-c is MONITORED but report-only (`hold`): it is ABI-pinned at 0.21.4
- * (#1242/#858) and must not auto-bump without a tree-sitter runtime upgrade, so an
- * available c update is detected + reported but never auto-applied — even if it is
- * ABI-13/14. A maintainer re-vendors it deliberately.

-name: Build tree-sitter prebuilds
-
-# Cross-builds the native tree-sitter prebuilds GitNexus vendors itself, so that
-# grammars whose upstream packages ship SOURCE ONLY (no usable prebuilds/) never
-# require a C/C++ toolchain at a user's install. This is the "no operational
-# risk for any tree-sitter grammar" pipeline.
-#
-# Grammars covered here (the at-risk set — everything else already ships 6
-# upstream prebuilds AND stays dependency-review-tracked, so it is left alone).
-# All five are vendored under gitnexus/vendor/; `kind` (below) only picks where
-# the build job fetches the C source to compile:
-#   - tree-sitter-c      (vendored prebuild-only; built from the published npm
-#                         package — closes upstream's 4/6 ARM gap #2116 for a
-#                         REQUIRED grammar)
-#   - tree-sitter-dart   (vendored source; built from gitnexus/vendor/)
-#   - tree-sitter-proto  (vendored source; built from gitnexus/vendor/)
-#   - tree-sitter-kotlin (vendored source; built from gitnexus/vendor/ — pinned to
-#                         an unreleased main commit for `fun interface` support
-#                         (#169) that no npm release carries yet)
-#   - tree-sitter-swift  (vendored source; built from gitnexus/vendor/ — its
-#                         prebuilds were originally upstream-shipped, now
-#                         GitNexus-cross-built like the rest for uniformity)
-#
-# Output: gitnexus/vendor/<grammar>/prebuilds/<platform-arch>/<grammar>.node for
-# all 6 targets ({linux,darwin,win32}-{x64,arm64}). tree-sitter grammars are
-# N-API, so one ABI-stable .node per platform-arch works across all Node majors.
-#
-# COST DISCIPLINE — this is a HEAVY native matrix (up to 3 grammars x 6 runners,
-# incl. macOS + arm64). It is DELIBERATELY NOT wired into normal PR/push CI. It
-# runs only:
-#   1. on manual dispatch (workflow_dispatch); or
-#   2. when a covered grammar's VENDORED SOURCE changes in a PR — a version bump
-#      OR an edit to the grammar's build-affecting source (parser.c / grammar.js /
-#      binding.gyp / scanner / bindings). The `guard` job is the real gate (it
-#      diffs BOTH the recorded version AND the source files vs the PR base); the
-#      `paths:` filter below keeps ordinary code PRs at ZERO matrix time and
-#      excludes the prebuilds the job commits back, so it never retriggers itself.
-# Net effect: an ordinary code PR triggers nothing; touching one grammar's source
-# costs exactly one matrix run for that grammar. Delivery of the rebuilt binaries:
-#   - same-repo PR  -> committed straight onto the PR's own branch (in the SAME PR);
-#   - manual dispatch (open_pr=true) -> a fresh chore/ PR;
-#   - fork PR -> the trusted commit-fork-prebuilds.yml (workflow_run) pushes them
-#                onto the fork branch when "Allow edits by maintainers" is on, else
-#                comments download-and-commit instructions. That consumer must be
-#                on the DEFAULT branch to run, so it activates once merged to main.
-#
-# Concurrency convention: see CONTRIBUTING.md -> "GitHub Actions — Concurrency Convention".
-#
-# NOTE: every action below is pinned to a release commit SHA (with the matching
-# `# vX.Y.Z` tag comment verified against the GitHub API). If a future bump adds
-# a new action, pin its real release SHA and allowlist it in .github/zizmor.yml /
-# Scorecard before merge.

-# `build-tree-sitter-prebuilds.yml` runs in the UNTRUSTED `pull_request`
-# context. On a fork PR it has a read-only token and no secrets, so it can
-# build + validate the native prebuilds and upload them as artifacts, but it
-# cannot commit them back. This workflow is the trusted consumer: triggered by
-# `workflow_run`, it runs from the DEFAULT BRANCH's copy of this file (the trust
-# anchor) with a writable token, downloads ONLY the artifacts (data — the
-# already-built-and-validated `.node` files + a small metadata.json), verifies
-# the metadata against the GitHub-controlled workflow_run authority, then pushes
-# the prebuilds onto the fork PR's head branch.
-#
-# It NEVER checks out or executes fork-controlled code: the producer already
-# `require()`-loaded + parsed each `.node` on its target platform in the
-# untrusted half (the correct place to run untrusted code). Here we only move
-# bytes and run git. The prebuilds touch ONLY gitnexus/vendor/<g>/prebuilds/**,
-# never .github/ — so the GITHUB_TOKEN's lack of `workflows` scope is irrelevant.
-#
-# Pushing to a fork branch with the GITHUB_TOKEN works only when the contributor
-# left "Allow edits by maintainers" enabled (the PR default) — the same
-# constraint as pr-autofix-apply.yml. When it's off we fall back to a comment.

-# Same-repo PRs do NOT come here: they have secrets in the producer run, so the

-# Off-the-fast-path mutation oracle for the PDG-backed `impact` mode.
-#
-# The `--mutation` oracle (bench/impact-pdg/measure.mjs) is a ~280s dynamic
-# value-diff check: it mutates each fixture, re-analyzes with `--pdg`, and scores
-# the realized recall of the statement slice against the behavioral diff. It is
-# far too slow for the PR critical path, so it runs on a nightly schedule (and on
-# demand via workflow_dispatch) and uploads the JSON report as an artifact rather
-# than gating merges.
-#
-# The harness shells out to `gitnexus analyze --pdg`, which spawns workers from
-# dist/, so dist must be built first — setup-gitnexus with build: 'true' does
-# that (mirrors ci-tests.yml).

-# UNTRUSTED HALF of the autofix pipeline.
-#
-# Runs `npm run lint:fix` + `npm run format` against the PR head
-# (including fork heads) and uploads the resulting diff as an artifact.
-# This job has NO privileged token and CANNOT post to the PR. The trusted
-# `pr-autofix-publish.yml` workflow downloads the artifact via
-# `workflow_run` and posts a sticky summary comment + Check Run.
-# Contributors apply the patch by commenting `/autofix` on the PR —
-# handled by the separate `pr-autofix-apply.yml` ChatOps workflow.
-#
-# Why the split:
-#   ESLint loads plugins from fork-controlled `node_modules`, so running
-#   it in a job with `pull-requests: write` would let a malicious fork PR
-#   ship a poisoned eslint plugin and execute arbitrary code under that
-#   token. By keeping fork code execution in this job (token: read-only)
-#   and posting from a separate trusted job that never touches fork
-#   code, we get the autofix UX for fork PRs without the supply-chain
-#   hole. (See autofix.ci for the same pattern.)
-#
-# Removes unused imports via `eslint-plugin-unused-imports`, already in
-# devDependencies and wired into the `lint` config.

-# Sole publisher for the `gitnexus` npm package, GitHub Releases, and Docker
-# images. Replaces the former two-workflow design — see issue #1609 for the
-# double-publish race this unification closes.
-#
-# Two release modes, both routed through this file:
-#   • Release candidate (rc)  — triggered by push to `main` or workflow_dispatch.
-#       The RC path computes the next rc version, applies it in-CI, pushes a
-#       detached release commit with v<X.Y.Z>-rc.<N> + rc/<SHA> marker
-#       atomically, then publishes to npm with --tag rc and creates a GitHub
-#       prerelease. RC-only docker.yml invocation follows.
-#   • Stable                  — triggered by push of a v<X.Y.Z> tag (no -rc.*
-#       suffix). Verifies package.json matches the tag, publishes to npm with
-#       --tag latest, creates a stable GitHub Release. No docker (RC-only).
-#
-# ⚠️  SELF-TRIGGER INVARIANT — DO NOT WEAKEN ⚠️
-# The `tags:` filter below uses a negative glob `'!v*-rc.*'` to prevent the
-# workflow from re-triggering itself when the RC path pushes its own v-tag.
-# Without this exclusion, every RC publish double-fires (the bug fixed by
-# #1609). If a NEW prerelease channel is introduced (e.g. `-beta.N`,
-# `-alpha.N`, `-next.N`), the negative-glob list MUST be extended in
-# lock-step or self-trigger returns. The same invariant applies to the
-# `Classify` step further below — its accepted-tag regex must align with
-# the trigger filter's exclusion list.

-          #   1. HEAD subject matches `chore: release vX.Y.Z` (the canonical
-          #      release-PR title). Anchored to require the bare title or the

-      #      tried because npm thinks it already has a credential.
-      #   2. The runner's bundled npm (10.9.x on Node 22) has no OIDC

-#   1. Peer-dep compatibility — can each NPM-installed grammar install cleanly
-#      with tree-sitter@0.25.0 without --legacy-peer-deps?
-#   2. Vendored grammars — each grammar in .github/vendored-grammars.json
-#      (c/swift/kotlin/dart/proto) is classified by its vendored ABI, read
-#      straight from gitnexus/vendor/<name>/src/parser.c (NOT node_modules,
-#      which is never populated for vendored grammars — that mismatch is why
-#      the report used to render bare "?" placeholders, #858).
-# See .github/scripts/check-tree-sitter-upgrade-readiness.py for the logic.
-#
-# .github/vendored-grammars.json is the SHARED source of truth for the vendored
-# SET + policy holds: this readiness report and grammar-update-monitor.yml both
-# read it, so the two workflows can never disagree about which grammars are
-# vendored. (The monitor also resolves upstreams from it; this report keeps its
-# own upstream-drift coords and reads vendored ABIs from gitnexus/vendor/.)
