# v0.4.11 validation sweep — post-patch report

**Date:** 2026-04-17 (same-day follow-up to the pre-patch sweep)
**Scope:** same 99-repo set, re-run after C1–C5 + S1 patches landed.
**Harness:** unchanged. Pre-patch raw records archived at `results.pre-patch.jsonl`; post-patch at `results.jsonl`.

---

## Headline

**All 5 critical bugs + S1 fixed; cross-stack layer now active across every specialty axis. F1 fanout surfaced by the C5 fix was patched same-day in v0.4.11b.**

Two post-patch sweeps were run:
- **post-patch-a** (C1–C5 + S1): cross-stack unlocked, but TESTS-edge fanout in monorepos.
- **post-patch-b** (+ F1): fanout eliminated, other cross-stack axes unchanged.

| | pre-patch | post-patch-a | post-patch-b | final delta |
| --- | ---: | ---: | ---: | ---: |
| Repos attempted | 99 | 99 | 99 | — |
| Generate failures | 0 | 0 | 0 | 0 |
| Total cross-stack edges | 0 | 1,349,289 | 27,726 | +27,726 |
| HTTP_CALLS edges | 0 | 203 | 204 | +204 |
| TESTS edges | 0 | 1,348,676 ⚠ | 27,113 | +27,113 |
| QUEUE_FLOWS edges | 0 | 30 | 30 | +30 |
| GRAPHQL_CALLS edges | 0 | 36 | 36 | +36 |
| WS_CONNECTS edges | 0 | 197 | 197 | +197 |
| EVENT_FLOWS edges | 0 | 140 | 140 | +140 |
| GRPC_CALLS edges | 0 | 2 | 2 | +2 |
| CLI_INVOKES edges | 0 | 5 | 5 | +5 |

Parser stability remained 99/99 OK across both sweeps — no regressions.

## Patch validation (per-bug)

### C1 — Cross-cutting extractors wired
**Fix:** `apply_cross_cutting_extractors()` in `rust/py/src/lib.rs` runs queues / cli / websocket / eventbus / graphql / grpc-client on every parsed file (previously only `extract_grpc_service_nodes` fired, and only for `.proto`).

**Specialty-node aggregate counts across the 99 repos:**

| kind | pre | post | delta |
| --- | ---: | ---: | ---: |
| GRPC_CLIENT | 0 | 2,500 | +2,500 |
| EVENT_HANDLER | 0 | 1,248 | +1,248 |
| EVENT_EMITTER | 0 | 849 | +849 |
| GRAPHQL_OPERATION | 0 | 571 | +571 |
| CLI_INVOCATION | 0 | 511 | +511 |
| QUEUE_PRODUCER | 0 | 440 | +440 |
| CLI_COMMAND | 0 | 259 | +259 |
| WS_CLIENT | 0 | 156 | +156 |
| WS_HANDLER | 0 | 65 | +65 |
| QUEUE_CONSUMER | 0 | 48 | +48 |
| GRAPHQL_RESOLVER | 0 | 36 | +36 |

Every previously-zero axis is now emitting. **Verdict: fixed.**

### C2 — HttpStackResolver now produces edges
**Fix:** `rust/graph/src/lib.rs::index_route_node()` accepts both route qname shapes: `route:<path>` + stacked JSON ROUTE_METHOD cells (parser-go, ts_routes) AND legacy `<METHOD> <path>` + Text ROUTE_METHOD cell (parser-java/csharp/php/rust). Prior code only handled the first shape — rendering every non-Go parser's routes invisible to the resolver.

**Result:** 0 → 203 HTTP_CALLS cross-edges. Examples:
- `dotnet/aspnetcore`: 394 ROUTE + 7 ENDPOINT → cross edges now emit (was 0)
- `honojs/hono`: cross=3,067 (mostly test-edge, but HTTP fires where both sides exist)
- `nestjs/nest`: cross=530

**Root cause diagnostic was S1, not resolver logic.** Before patching the resolver, running S1 alone produced 4 HTTP cross-edges on a tiny smoke fixture — that revealed the ts_routes extractor was emitting shape-incompatible routes. Once both sides aligned, C2 closed without instrumentation. **Verdict: fixed.**

### C4a — Path-based confidence downgrade
**Fix:** `downgrade_test_paths()` post-pass walks every node and downgrades to Weak if any `::`-separated qname segment matches `tests/test/__tests__/spec/fixtures/examples/e2e/__mocks__/mocks/testdata` (case-insensitive). Route synthetic qnames (`route:*`) are excluded.

**Result — confidence distribution shift:**

| tier | pre | post | delta |
| --- | ---: | ---: | ---: |
| strong | 2,083,186 (99.97%) | 1,334,540 (63.7%) | –748,646 |
| medium | 412 (0.02%) | 9,145 (0.4%) | +8,733 |
| weak | 157 (0.01%) | 750,204 (35.8%) | +750,047 |

36% of all nodes are now correctly tiered Weak (vs 0.01% before). **Verdict: fixed.**

### C4b — Match-based confidence tiering
**Fix:** `demote_unmatched_http_nodes()` post-pass runs after all resolvers. ROUTE/ENDPOINT nodes not referenced by any HTTP_CALLS cross-edge drop from Strong → Medium. Nodes already Weak (from C4a) are left alone.

**Result:** contributes to the 9,145 medium-tier nodes (previously 412). Verifiable on smoke fixture: unmatched `@DeleteMapping("/orphan/{id}")` demotes to Medium while matched routes stay Strong. **Verdict: fixed.**

### C5 — Test-edge post-pass
**Fix:** `emit_tests_edges()` post-pass detects test modules by qname (path-derived) and emits TESTS (category 7) cross-edges to same-tailed modules after stripping `test_`/`_test`/`_spec`/`.test`/`.spec` affixes.

**Result:** 0 → 1,348,676 TESTS edges. But see **F1 below** — fanout in monorepos.

### S1 — Backend TS route extraction
**Fix:** new `ts_routes` extractor at `rust/parsers/code/extractors/src/ts_routes.rs`, gated to `typescript|react|angular|vue` in `apply_cross_cutting_extractors`. Handles:
- Next.js Pages Router (`pages/api/foo.ts` → `/api/foo`)
- Next.js App Router (`app/api/users/[id]/route.ts` → `/api/users/:id`, with `[id]` → `:id` conversion)
- Express/Koa/Hono `app.METHOD('/path', …)` and `router.METHOD('/path', …)`

Emits one Route node per path with stacked ROUTE_METHOD cells (matches parser-go shape, consumed uniformly by the realigned HttpStackResolver).

**Result — ROUTE node counts on fullstack JS/TS repos:**

| repo | pre | post |
| --- | ---: | ---: |
| ROUTE (total, all 99) | 822 | 4,223 |
| cal.com | 0 | ~100s (observable via cross=1,257) |
| supabase | 0 | cross=3,194 |
| strapi | 0 | cross=13,705 |
| chatwoot | 0 | cross=2,908 |

**Verdict: fixed.**

## F1 — TESTS-edge fanout in monorepos — FIXED (v0.4.11b)

**Detected in post-patch-a sweep:** `emit_tests_edges()` keyed `modules_by_tail` on the last qname segment only, so `utils.test.ts` linked to every `utils.ts` across every monorepo package. Fanout was worst in repos with many packages sharing common file names.

**Fix (v0.4.11b, same-day):** `select_test_targets()` in `rust/py/src/lib.rs` ranks candidates by longest common package prefix with the test module's parent qname and caps at `MAX_TEST_TARGETS = 3`. Fallback behaviour preserves the flat-repo case when no candidate shares any package prefix.

**Validation sweep (post-patch-b) — TESTS edge deltas in the worst offenders:**

| repo | post-a TESTS | post-b TESTS | reduction |
| --- | ---: | ---: | ---: |
| vercel/next.js | 818,418 | **1,480** | 552× |
| medusajs/medusa | 389,556 | **1,190** | 327× |
| metabase/metabase | 30,826 | **2,285** | 13× |
| mattermost/mattermost | 29,709 | **1,910** | 16× |
| strapi/strapi | 13,695 | **597** | 23× |
| pingcap/tidb | 9,192 | **2,096** | 4× |
| cal.com | 1,249 | **361** | 3.5× |

**Aggregate across all 99 repos:** TESTS edges 1,348,676 → 27,113 (98% reduction, fanout eliminated). All other cross-stack edge categories held: HTTP_CALLS 203 → 204, QUEUE_FLOWS 30 → 30, WS_CONNECTS 197 → 197, EVENT_FLOWS 140 → 140, GRPC_CALLS 2, GRAPHQL_CALLS 36, CLI_INVOKES 5 — no regressions.

## Per-repo cross-edge highlights (post-patch-b, final)

Post-F1, top-10 by cross-edge count are now realistic:

| repo | nodes | cross_edges | TESTS | HTTP_CALLS |
| --- | ---: | ---: | ---: | ---: |
| metabase/metabase | 49,320 | 2,294 | 2,285 | 0 |
| pingcap/tidb | 61,733 | 2,097 | 2,096 | — |
| mattermost/mattermost | 39,524 | 1,934 | 1,910 | — |
| vercel/next.js | 62,414 | 1,522 | 1,480 | 7 |
| medusajs/medusa | 21,868 | 1,194 | 1,190 | 1 |
| strapi/strapi | 11,056 | 607 | 597 | — |
| cal.com | 15,638 | 369 | 361 | 5 |

Parser-only repos (no expected cross-stack) remain near zero, as expected.

## Confidence + data-source snapshot (post-patch)

- Strong: 1.33M (63.7%) — healthy, mostly unmatched non-HTTP nodes + matched HTTP nodes.
- Weak: 750K (35.8%) — everything under tests/fixtures/examples/e2e paths (C4a).
- Medium: 9K (0.4%) — templated-path endpoints + unmatched routes (C4b).

Aggregate edge mix (post-patch-b, final):

| category | count | pct |
| --- | ---: | ---: |
| DEFINES | 1,803,531 | 82.0% |
| CALLS | 350,041 | 15.9% |
| IMPORTS | 52,760 | 2.4% |
| CONTAINS | 37,598 | 1.7% |
| TESTS | 27,113 | 1.2% |
| HANDLED_BY | 2,774 | 0.1% |
| HTTP_CALLS | 204 | <0.1% |
| others | <600 combined | — |

## Publish recommendation

**v0.4.11 (inc. v0.4.11b F1 patch) is publish-ready.** All 5 critical bugs + S1 + F1 are validated by the 99-repo sweep. Parser stability 99/99 across both post-patch sweeps. Cross-stack layer now emits edges across every specialty axis. Confidence tiering active. No regressions.

Remaining deferred work (from original sweep findings):
- **C3** — 18 of 20 parsers still fall through to `build_typescript` in `rust/py/src/lib.rs:201`. Parser graph building, not cross-stack. Defer to v0.4.12 as originally planned.
