Seven vulnerability families are declared and two had been proven. The census asks each of them, on whole checkouts of NodeGoat and VAmPI, whether it establishes anything at all, and reports a family that answered and found nothing separately from one that was never asked. Four establish findings: injection, access_control, config_secrets and untrusted_destination. Output encoding, path, prototype and deserialization establish nothing on either subject. All 299 NodeGoat and 35 VAmPI questions completed, so the silences are answers. Three of those silences are diagnosed gaps, not clean code. NodeGoat's documented SSRF calls needle.get, which the sink vocabulary does not hold. Its XSS is server-rendered, and output encoding declares only DOM sinks, so no question it can ask could have found it. Its two access-control defects raise no obligation at all: measured with the real dominance query, every modelled data operation lives in app/data/*-dao.js and none in a route handler file, while the family scopes operations to the region's own file. Tasks 14.2 to 14.5 carry each gap; none is fixed here. The census also found a false positive and it is fixed. NodeGoat's only prototype report was the word `set` inside `// set these up in case we have an error case`: the matched node is the <operator>.assignment holding the entire 1,000-character signup handler, and sinkMatches searched a node's whole text. It now confines the text clause to the callee and excludes operator nodes. Fourth instance of this bug class after fgets/gets, resolve/resolveUrl and user/users. Measured on NodeGoat's non-vendor calls, injection sinks fall 28 to 3, prototype 13 to 2 and untrusted destination 26 to 7, with no true positive lost; req.query had been an injection sink because `query` is word-bounded inside it. Witnesses now name the sink call rather than the assignment that contained it. 1,411 tests pass, ten skipped; the six Joern-gated query tests pass in the image, including a new one that fails on the shape this fixed.

# Pre-push safety net status — v1.2.0-alpha.1
|
||
|
||
Updated 2026-09-16. Phase: **implementation**. Requirements, design and tasks are
|
||
approved. **28/29 executable tasks complete; task 8.3 remains blocked.**
|
||
Rollout: **NO-GO**. The alpha tag publishes experimental implementation and evidence;
|
||
it does not approve normal hook capabilities or production enforcement.
|
||
|
||
## Next release milestone
|
||
|
||
**M1a is met and the M1b comparison now works through the production rules.** The other four
|
||
milestones remain unverified, and rollout remains NO-GO.
|
||
|
||
Every veto M1a recorded has been repaired. On 2026-09-16 the production comparison classified
|
||
the pinned NodeGoat revisions without any lifting: the vulnerable revision is `new` with the
|
||
three `eval` witnesses attributed to the change that introduced them, the fixed twin is
|
||
analyzed and quiet, and the unchanged revision is `unchanged`. Production and the recorded view
|
||
agree exactly, which is how we know the vetoes were repaired rather than bypassed. No capability
|
||
is enabled, no defect is admitted and no alert is emitted. See
|
||
[M1a and M1b evidence](m1a-recorded-vetoes.md).
|
||
|
||
The exit run is recorded. Every veto M1a listed is repaired, plus two the repairs exposed: the
|
||
comparison's own degradation and boundary checks, and the runner handing every candidate the
|
||
whole transaction's gaps. On the vulnerable revision admission now rejects on
|
||
`capability_unavailable` alone.
|
||
|
||
One half of M1b remains. The milestone also asks for a developer-readable finding carrying a
|
||
supported security consequence and a concrete repair direction. Both are owned by an evaluated
|
||
capability declaration and the registry is deliberately empty, so nothing renders them. Writing
|
||
that text without a declaration is what admission exists to prevent, so it is not worked around.
|
||
Task 10.10 renders it through an explicitly experimental declaration with eligibility still
|
||
disabled.
|
||
|
||
M1a ran on 2026-09-16 within its one-week box. The raw `<lambda>2` witnesses are present at
|
||
contributions.js lines 32–34, the fixed twin was genuinely analyzed and quiet, and the
|
||
unchanged revision was not reported as a new regression, so the kill criterion did not
|
||
trigger. Five vetoes fired and were recorded; with all five lifted the detection still stops
|
||
at `operation_correspondence_unresolved`, because a newly introduced operation sits on a
|
||
changed line and has no base anchor. That fifth veto was not in the earlier diagnosis and is
|
||
now M1b's central repair. See [M1a evidence](m1a-recorded-vetoes.md).
|
||
|
||
The 28/29 task count is implementation progress, not proximity to rollout. Follow the
|
||
accepted [release milestone spec](release-milestones.md): usefulness → speed → shared
|
||
PHP/Python transfer → independent qualification → narrow advisory rollout.
|
||
|
||
## Security capability, 2026-09-17
|
||
|
||
Group 12 closed three defects that limited what the tool can establish, each measured on the
|
||
pinned NodeGoat revisions with detections unchanged throughout.
|
||
|
||
- **Access control could not answer anywhere.** Dominance and configuration were never asked for
|
||
change context, because the evidence pass dispatches taint only. Each family now describes its
|
||
own scope. Head completion rose from 205 to 298 of 436, `context_projection_unavailable` fell to
|
||
zero, and access control went from 0 to 52 completed questions.
|
||
- **Admission rejected genuine findings.** The operation symbol was the text before the first
|
||
parenthesis, so `const preTax = eval(...)` was the operation `const preTax = eval`, which no
|
||
qualified declaration could ever name. It is now the trailing qualified callee, with receiver
|
||
spelling preserved.
|
||
- **Unresolved questions said why, and then there were none.** The remaining 138 each named a
|
||
function its file does not define. A route-registration module registers handlers other modules
|
||
define, and regions were scoped to methods those files do not hold. The entry record keeps the
|
||
handler name, because the authorization question is cross-file by nature, and the region is now
|
||
scoped to the file instead. **Every question the scan asks now completes on both revisions,
|
||
299 of 299**, with detections unchanged.
|
||
|
||
Evidence: [group 12 final](../../../benchmarks/measurements/2026-09-17-group-12-final.json) and
|
||
[region attribution](../../../benchmarks/measurements/2026-09-17-region-attribution.json).
|
||
|
||
## Verified
|
||
|
||
Immutable pushed snapshots, shared multi-ref deadlines, ranker-owned scope, physical
|
||
vendor exclusion, compatible immutable graph/result reuse, actionability admission,
|
||
compact truthful reporting and non-destructive hook integration are implemented.
|
||
Advisory and blocking share the same evidence bar; optional model output cannot bypass it.
|
||
|
||
Contributor-scan task 2.19 is verified: the pinned frontend now retains the original
|
||
Gruntfile, bringing the real NodeGoat census from 43/44 to 44/44 files. Partial, absent
|
||
and malformed census no longer masquerade as a complete result or a falsely empty graph.
|
||
The final code verification recorded 1321 passed tests, nine skipped, passing canonical
|
||
gates and a packaged native PHP/JavaScript partition smoke. See
|
||
[owner verification](../contributor-scan/census-repair-verification.md).
|
||
|
||
## Rollout blockers
|
||
|
||
1. **Useful checks within the deadline are unproven.** The fresh post-census profile
|
||
completed all 21 measurements: all 18 changed/cold/growth/multi-ref transactions timed
|
||
out; the three identical-tip replays took 18.521–18.874s with valid graph/query reuse.
|
||
Still 0/24 declared target checks completed. Maximum observed cancellation/report
|
||
overrun was 0.874s, below the two-second allowance. After M1 establishes the useful
|
||
comparison, amortize engine startup/loading and rerun the frozen seven-class profile; require warm p95 <=30s and >=95% completed supported checks.
|
||
2. **Target and change-context evidence remains incomplete.** M1a measured exactly which
|
||
contracts fail on the Node case: per-family change context, question-owned vendor
|
||
relevance, operation correspondence for changed lines, file-wide correspondence ambiguity
|
||
and query-to-operation provenance. VAmPI preserves raw findings
|
||
at all three known sites, but the exact SQLI function question/transitive witness and
|
||
supported authorization context are unresolved. Raw findings or rank positions cannot
|
||
establish an actionable new regression. Repair this in the shared scan boundary and
|
||
verify the actual associated query/path evidence.
|
||
3. **Independent quality qualification is missing.** Freeze and review untouched Node API
|
||
vulnerable/fixed/benign cases, including middleware/module/async context. Ghost remains
|
||
reserved with missing reviewed inputs. PHP and Python need their own independent
|
||
language/framework/family populations; Node results cannot qualify them. Require >=95%
|
||
observed actionable precision with counts/intervals, >=90% supported recall, nonzero
|
||
reviewed emitted alerts/positive controls and zero known fixed/benign false alerts.
|
||
4. **No current capability is eligible.** The earlier registry is NO-GO and becomes stale
|
||
under the repaired runtime/core identities. Loading it enables zero capabilities.
|
||
After the preceding evidence passes together, regenerate exact-semantic eligibility
|
||
and rerun packaged acceptance validation. Do not relabel old measurements as current.
|
||
|
||
C/libpng arithmetic and bounds remain explicitly unsupported; this is not a C/C++
|
||
detection qualification. Advisory rollout cannot be justified by silence from an
|
||
unqualified registry.
|
||
|
||
## Ownership and revalidation
|
||
|
||
Engine lifecycle, source/census and context/witness normalization belong to
|
||
`contributor-scan`. The hook consumes those contracts; no second engine, source IR,
|
||
ranker priority exceptions or differential graph mutation is introduced here. Graph
|
||
mutation would need a separate cold-equivalence experiment.
|
||
|
||
After owner fixes, refreeze identities and rerun ordinary scan gates, Python regressions,
|
||
PHP-to-Node transfer, the representative cache/deadline profile, independent per-capability
|
||
quality evaluation and packaged hook validation. Keep task 8.3 unchecked and the feature
|
||
in implementation until those mandatory results are established.
|
||
|
||
Evidence: [group 8 validation](validation-group-8.md),
|
||
[post-census runtime scorecard](../../../benchmarks/measurements/2026-09-14-nodegoat-post-census-feasibility.json),
|
||
[census repair](../../../benchmarks/measurements/2026-09-14-node-census-repair.json).
|
||
|
||
The owner investigation now distinguishes missing family context producers, globally
|
||
propagated vendor/correspondence gaps, and query-to-operation identity. See
|
||
[remediation research](../contributor-scan/release-remediation-research.md). These are
|
||
next implementation prerequisites, not completed fixes or changed acceptance gates.
|
||
|
||
An isolated Joern session probe matched the full Node census with four warm requests in
|
||
0.221–0.467s and verified cancellation/reaping in 0.043s. It identifies a promising engine
|
||
lifecycle change; full-query equivalence and changed-code performance remain unverified.
|
||
|
||
## Family detection census, 2026-09-19
|
||
|
||
Four of seven declared families establish findings on the two development subjects:
|
||
injection, access_control, config_secrets and untrusted_destination. Output encoding, path,
|
||
prototype and deserialization have established nothing anywhere. Every question completed on
|
||
both subjects, 299 of 299 on NodeGoat and 35 of 35 on VAmPI, so the silences are answers
|
||
rather than failures — but three of them are diagnosed gaps rather than clean code:
|
||
NodeGoat's documented SSRF is invisible because `needle.get` is not in the sink vocabulary,
|
||
its XSS is invisible because output encoding declares only DOM sinks, and its two
|
||
access-control defects raise no obligation because the modelled data operations live in DAO
|
||
files while the family's scope is the handler's own file.
|
||
|
||
The census also found and fixed one false positive: NodeGoat's only prototype report was
|
||
the word `set` in a code comment, matched because the sink text clause searched a whole
|
||
assignment node. Nothing about this changes the release gates. No capability is qualified by
|
||
these subjects.
|
||
|
||
Evidence: [family detection census](../../../benchmarks/measurements/2026-09-19-family-detection-census.json).
