Each tool script in `/usr/local/bin/` is standalone — no sourcing, no env inheritance needed. This is critical because mini-swe-agent runs every command via `subprocess.run` in a fresh subshell.
@ -176,6 +176,59 @@ The eval-server is a lightweight HTTP daemon that:
- Includes next-step hints to guide tool chaining (query → context → impact → fix)
- Auto-shuts down after idle timeout
**CLI flags:**
| Flag | Default | Purpose |
|------|---------|---------|
| `--port <port>` | `4848` | Port to listen on |
| `--host <host>` | `127.0.0.1` | Bind address — use `0.0.0.0` for cross-container access |
| `--idle-timeout <seconds>` | `0` (disabled) | Auto-shutdown after N seconds of inactivity |
**READY signal:**
When the server is ready, it writes to stdout:
```
# IPv4
GITNEXUS_EVAL_SERVER_READY:127.0.0.1:4848
# IPv6 (bracketed to avoid colon ambiguity)
GITNEXUS_EVAL_SERVER_READY:[::1]:4848
```
Parse the port as the last colon-segment (`split(':').pop()`) — not `split(':')[1]`, which breaks for IPv6 and for non-loopback IPv4 hosts added in this release.
### Custom port and host
`run_eval.py` does not expose `--port` or `--host` as CLI flags. Configure them in your mode YAML under the `environment:` key:
```yaml
# configs/modes/native_augment.yaml (or whichever mode you're running)
environment:
eval_server_port: 4849 # change if 4848 is already in use on the host
eval_server_host: "0.0.0.0" # bind all interfaces — needed for cross-container setups
```
Defaults are `port: 4848` and `host: 127.0.0.1` (loopback only). Use `0.0.0.0` only when the agent container needs to reach the eval-server from a separate network namespace. The health probe and tool scripts connect via the configured bind host (defaulting to `127.0.0.1`), which is reachable for both loopback and all-interface binds.
**Running eval-server directly in Docker / Docker Compose:**
```bash
# Bind to all interfaces so sibling containers can reach it
gitnexus eval-server --host 0.0.0.0 --port 4848
# Then probe from a sibling container via its service hostname
curl http://eval-container:4848/health
```
If you need a non-default port (e.g. to avoid conflicts), pass `--port <port>` alongside `--host`. The READY signal will reflect both:
```
GITNEXUS_EVAL_SERVER_READY:0.0.0.0:5000
```
Parse the port as the last colon-segment (`split(':').pop()`) — safe for both IPv4 and bracketed IPv6 forms.
### Index caching
SWE-bench repos repeat (Django has 200+ instances at different commits). The harness caches GitNexus indexes per `(repo, commit)` hash in `~/.gitnexus-eval-cache/` to avoid redundant re-indexing.

## [Unreleased]
## [1.6.5] - 2026-05-16
### Added
- **C++ ADL V2** — Argument-Dependent Lookup overhaul. Class-typed reference args (incl. rvalue refs) contribute associated namespaces (#1595); class-pointer args and template-specialization args (with nested template args) included (#1592, #1596); base-class associated namespaces walked via MRO (#1597); free-function reference args contribute enclosing namespace (#1598); ordinary and ADL free-call candidates merged before overload selection (#1599)
- **C++ standard-conversion-sequence ranking** for overload resolution (#1606)
- **C++ scope-resolution migration** — C++ now runs on the registry-primary RFC #909 path (#938, #1520); template-body `this->` + `using ns::name` calls resolved in the scope resolver (#1590); template specializations disambiguated in class graph IDs and receiver routing (#1587); EXTENDS edges for template and qualified template bases (#1581)
- **PHP scope-resolution migration** — PHP moved to scope-based resolution (#938, #1497, supersedes #1124)
- **Java scope-resolution migration** — RFC #909 Ring 3 (#1482)
- **C scope-resolution migration** — RFC #909 Ring 3 (#1481)
- **Incremental indexing** — `gitnexus analyze` now reuses a parse cache, writes back to DB, and short-circuits scope resolution when nothing changed (#1479)
- **`gitnexus:keep` marker** — preserves custom context sections (#605, #1508)
- **`gitnexus analyze --skip-skills` and `--index-only`** flags (#742, #1485)
- **`gitnexus wiki --timeout` and `--retries` flags** — mitigate timeout aborts on large module pages (#1543)
- **HTTP embedding `dimensions` parameter** — now forwarded to the embedding endpoint (#1498)
- **Cursor 2.4 `postToolUse` hooks** — upgraded for Read/Grep/Shell coverage (#1467)
### Fixed
- **Cross-file type propagation** — resolved a stall on large repos (#1626)
- **C++ inline-namespace ambiguity** — detect same-name ambiguity across inline namespace children (#1564, #1600); workspace-wide dependent-base name resolution for cross-file templates (#1586)
- **Parse cache persistence** — sharded on large repos to avoid corruption (#1580)
- **TypeScript ESM `.js` extension** — fallback applied to tsconfig path-alias resolution (#1530) and `.js` → `.ts` source resolution (#1525)
- **Markdown CRLF line endings** — section heading parser now handles them (#1469)
- **`gitnexus analyze --no-stats`** — actually omits volatile counts (#1477, #1478)
- **`ensureGitNexusIgnored`** — tolerate read-only workspaces (#1549, #1550)
- **Claude augment hook** — skipped when GitNexus server owns the DB (#1493)
- **Docker runtime image** — symlink `gitnexus` binary onto `$PATH` (#1551); install `ca-certificates` for TLS verification (#1545, #1547); include duckdb installer script (#1502)
- **Windows reliability** — fix 32767-char tree-sitter crash and VECTOR-extension SIGSEGV (#1433); platform-aware `tsc` build command for win32 (#1531)
- **Search / FTS** — guard against undefined `bm25Results` when FTS is unavailable (#1489, #1540); CONTAINS fallback in augment when FTS indexes unavailable (#1476)
- **Wiki** — sanitize generated mermaid diagrams (#1539)
- **Hooks** — cap concurrent augment subprocesses to prevent runaway fan-out (#1486, #1510)
- **LadybugDB** — drain checkpoint result before close (#1506); recover `gitnexus analyze` from orphan sidecars when the main DB file is missing (#1622)
- **Group / contracts** — detect `httpx` async consumers (#1408)
- **Server hardening** — sanitize repo name to prevent argument injection on `/api/analyze` (#1305)
### Changed
- **CI release pipeline unified under `publish.yml`** — single source of truth for npm publish, provenance, and GitHub Release creation (#1610)
- **CI: skip RC build on release PRs** — release/* branches no longer cut redundant RCs (#1474)
- **CI (Claude review): make `/review` reliably post PR comments** (#1522); allow Bash in code-review job without interactive approval (#1523)
- **CI publish (post-merge fixes)** — bump publish job to Node 24 for npm OIDC support (#1628); engage npm Trusted Publishing OIDC properly (#1627)
- **Tests** — remove flaky regression test for resource exhaustion (#1521); de-flake regex linearity assertions in U8 (#1475)
### Chore / Dependencies
- `vitest` 4.1.5 → 4.1.6 in /gitnexus (#1605)
- `@langchain/google-genai` bump in /gitnexus-web (#1554)
- `vite` 8.0.10 → 8.0.11 in /gitnexus-web (#1555)
- `mermaid` bump (#1514)
- `protobufjs` 7.5.5 → 7.5.8 + `@protobufjs/utf8` in /gitnexus (#1535, #1536)

AFTER THIS: Review affected processes. Use context() on high-risk symbols. READ gitnexus://repo/{name}/process/{name} for full traces.

/**
* Tests for WAL corruption detection in the doInitLbug schema creation loop.
*
* Before this fix, a corrupt WAL that threw during schema DDL was silently
* logged as WARN. After the fix, `isWalCorruptionError` is checked first:
* the DB is closed cleanly and an Error with `WAL_RECOVERY_SUGGESTION` is
* thrown so the caller (serve / MCP / analyze) can exit with a clear message.
*
* Two test layers (same pattern as lbug-checkpoint-lifecycle.test.ts):
* 1. Structural — grep the adapter source to verify the guard is wired in.
* 2. Behavioural — vi.doMock + vi.resetModules to exercise the runtime path.
