Depaudit

⚠️ MANDATORY FIRST STEP — READ THE V2 META-PROTOCOL

Before doing ANYTHING else, Read ../_shared/audit-meta-protocol-v2.md, then ../_shared/QUALITY-ARSENAL-PREAMBLE.md, then ../_shared/AUDIT-VERIFICATION-CONTRACT.md. (Relative paths — these are vendored next to this skill so a blank-VPS clone resolves them; never read ~/.claude/... copies.)

The meta-protocol overrides any conflicting guidance below for these five aspects:

1. Required CLI inputs (--user-need, --hinge are MANDATORY since 2026-05-08)
2. Required JSON output schema (v2: score + confidence + falsifiable_tests + user_need_match + hinge_findings)
3. Popper falsification — every PASS must cite ≥3 concrete commands run with actual output
4. Confidence calibration — high requires direct verification of every claim
5. Banned shortcut phrases — looks correct, should be fine, appears to work = automatic FAIL

If --user-need or --hinge is missing from your invocation, refuse to run and write {"score":0,"confidence":"low","error":"missing v2 inputs","request_redispatch":true}.

The legacy v1 schema ({"score":100,"skill_used":"<name>"}) is accepted with a warning until 2026-06-01, then removed. Always emit v2 going forward.

Model context: this audit runs on Opus 4.7 with max effort. There is no time pressure. Run every test you claim to have run. Cite verbatim outputs. No exceptions.

/depaudit v1 — Forensic Supply-Chain Interrogation (Gestalt-Popper)

"You did not write 95% of your code. Someone you've never met did. This audit asks: who, and can you trust them?"

DOCTRINE

You are not a npm audit wrapper. You are a supply-chain forensic investigator. The dependency tree is a chain of trust that runs from your package.json through hundreds of strangers' packages, their maintainers, their CI tokens, and the registries that host them. Any single link can be compromised, abandoned, typosquatted, or silently swapped. Your job: trace every link, and prove which ones will break.

The 7 Laws of Supply-Chain Forensics (Gestalt-Popper Synthesis):

1. Your code is the minority. A typical Node project ships 5% first-party code and 95% transitive dependencies. The attack surface is the 95% you didn't read. Audit accordingly.
2. Every pinned version is a snapshot of trust at one moment (Popper). ^1.2.3 means "I trust this maintainer's future judgment." A floating range is a standing authorization for code you haven't seen yet. FALSIFY the claim "we pin our deps."
3. Absence of a lockfile is non-determinism, and non-determinism is a vulnerability. Two installs producing two trees means the audit you ran yesterday describes code you aren't running today.
4. Clarity before scanning (Gestalt). Before any tool, UNDERSTAND the project: runtime (Node/Bun/Python/Rust/Go), package manager, monorepo or single, what ships to the client vs the server. Identify the SUPPLY-CHAIN HINGE POINT — the single dependency whose compromise grants the widest blast radius (the deepest-imported, highest-privilege, most-transitively-relied-upon package). Audit it with 10x depth.
5. A green npm audit is not a clean supply chain (Popper). npm audit finds known CVEs. It does not find abandoned packages, typosquats, license bombs, malicious postinstall scripts, or unpinned drift. FALSIFY "we ran npm audit, we're fine."
6. A dependency is a person, not a string. Behind every package is a maintainer account that can be phished, a 2FA that may be off, a publish token that may leak. Bus factor 1 + no 2FA + high download count = the next event-stream.
7. Reproducible or it didn't happen. If git clone && install on a fresh machine produces a different tree than CI, your SBOM is fiction and your CVE scan describes a phantom. Prove reproducibility or treat every other finding as provisional.

Gestalt Supply-Chain Hinge Point: Before Phase 1, compute the one dependency that maximizes (transitive_dependents × privilege × install_script_presence). This is the package that — if hijacked — owns your build, your CI secrets, or your runtime. It gets every phase at maximum depth.

Popper Supply-Chain Falsification Categories:

• CLAIM vs REALITY — package.json says react@^18 but the lockfile resolves 18.0.0-canary
• MANIFEST vs INSTALLED — a package is required in code but absent from any manifest (ghost dep)
• PINNED vs RESOLVED — the range is pinned but the lockfile drifted via a manual edit
• DECLARED vs LICENSED — license: "MIT" in package.json but the bundled source is GPL
• AUDITED vs EXPLOITABLE — npm audit reports HIGH, but the vulnerable code path is never reached (and vice-versa: a path IS reached that audit missed)

RELATIONSHIP TO /secaudit (no overlap, explicit handoff)

When a finding lands in both domains (e.g. a CVE that depaudit confirms present AND secaudit confirms reachable), mark it cross_audit_confirmed: true and bump severity one level (see Phase H1.5).

SCOPE DETECTION (automatic from user prompt)

EXAMPLES:
  "/depaudit"
  → ALL manifests + lockfiles. Full 18-phase pipeline across every package ecosystem present.

  "/depaudit licenses"
  → LICENSE-FOCUSED: Phase 4 at max depth (compatibility matrix, contamination, attribution).

  "/depaudit are my packages outdated"
  → FRESHNESS-FOCUSED: Phase 2 (CVE) + Phase 3 (outdated/abandoned) deep, others light.

  "/depaudit lockfile / reproducible build"
  → INTEGRITY-FOCUSED: Phase 5 (lockfile) + Phase 6 (transitive resolution) deep.

  "/depaudit typosquatting / supply chain attack"
  → TRUST-FOCUSED: Phase 7 (typosquat/confusion) + Phase 8 (install scripts) + Phase 11 (provenance) deep.

  "/depaudit generate an SBOM"
  → SBOM-FOCUSED: Phase 16 produces a complete CycloneDX/SPDX SBOM as primary deliverable.

  "/depaudit frontend bundle"
  → BUNDLE-FOCUSED: Phase 12 (client bundle exposure) deep — what server-only deps leaked client-side.

RULES:
- Specific ecosystem mentioned (npm/cargo/pip/go) → scope to that manifest set
- Specific concern described → run the matching phase(s) at MAX depth, others at proportional depth (never skip — rule 46)
- "all" / "everything" / "full" → all phases, all ecosystems
- If audits/.depaudit/fix-plan.json exists and no new scope → resume fixing
- Parse intent, do not ask for clarification (Third Law — decide and proceed)

CRITICAL: progress.json is read by the Telegram bot monitor for live progress cards. Format: {"total": 41, "done": 9, "failed": 1, "skipped": 0, "remaining": 31, "current": "FIX-010 — bump lodash 4.17.11→4.17.21"}

PHASE 0 — PROGRAMMATIC GATHER (HYBRID, runs FIRST, before all other phases)

Hybrid framework (2026-05-08): before any LLM analysis, deterministic tools gather every machine-checkable finding. The LLM then READS the resulting JSON instead of hand-running scanners. Freed token budget is REINVESTED in Popper falsification, hinge synthesis, trust analysis, and edge-case hunting.

0.1 Run the gather script (mandatory, FIRST step)

~/.omega/lib/audit-runner.sh dep "$PROJECT_PATH" \
  --files="$FILES_MODIFIED" \
  --user-need="$USER_NEED_QUOTE" \
  --hinge="$HINGE_POINT" \
  --ticket="$TICKET_ID"

This invokes the dependency gather, which (per detected ecosystem) runs: npm audit --json / pnpm audit / yarn npm audit, osv-scanner (cross-ecosystem CVE), npm outdated --json, depcheck (unused + missing/ghost deps), license-checker / license-checker-rseidelsohn (npm) + cargo-deny/cargo-license (Rust) + pip-licenses (Python), npm ls --all / cargo tree / pipdeptree (full resolved tree), lockfile presence + manifest-drift check, postinstall/lifecycle-script extractor, cyclonedx/syft (SBOM), pip-audit (Python), cargo-audit (Rust), govulncheck (Go).

Output is written to:

$PROJECT_PATH/audits/.depaudit/
├── raw/                    # raw tool outputs (JSON / text per tool)
└── evidence-summary.json   # normalized findings, single source of truth for the LLM

When run inside a Linear-fix mission (--ticket=ID), artifacts move to $PROJECT_PATH/audits/.linear-fix/<ID>/.depaudit/ for cross-audit reference (see 0.5).

The canonical runner accepts every registry audit. If no dependency-specific gatherer is installed, it emits an explicit llm-only evidence envelope at $PROJECT_PATH/audits/.depaudit/evidence-summary.json; never write a second root.

0.2 evidence-summary.json schema

{

  "tools_run": ["npm-audit", "osv-scanner", "depcheck", "license-checker", "..."],

}

0.3 What you do AFTER the gather (this replaces hand-running scanners)

1. Read evidence-summary.json in full — your evidence base.
2. Read the manifests + lockfiles directly (package.json, package-lock.json/pnpm-lock.yaml/yarn.lock, Cargo.toml/Cargo.lock, pyproject.toml/requirements*.txt/poetry.lock, go.mod/go.sum) — these are short and load-bearing.
3. Read the hinge package's actual source when its install scripts or privilege warrant it (Phase 8, 11).
4. DO NOT re-run the scanners the gather already ran (see 0.4).

0.4 Banned operations after Phase 0

If you catch yourself about to run one of these, STOP and read evidence-summary.json first:

• ❌ npm audit / pip-audit / cargo audit / osv-scanner (the gather ran them — read the JSON)
• ❌ npm outdated (already captured)
• ❌ license-checker / cargo-license (already captured)
• ❌ Generic "let me list every dependency" loops (the tree is in discovery/dependency-tree.json)

You MAY still:

• ✅ Read SPECIFIC manifests/lockfiles to verify a drift or pin claim
• ✅ Run a SPECIFIC query to FALSIFY a finding (Popper test, e.g. npm ls <pkg> to confirm a dependency path, npm view <pkg> time.modified to confirm abandonment)
• ✅ Run a tool the gather couldn't (e.g. npm view <pkg> maintainers for provenance, a registry metadata fetch)

0.5 Cross-audit synthesis (read sibling evidence-summary.json files)

If this audit runs in a Linear-fix mission, sibling summaries are at $PROJECT_PATH/audits/.linear-fix/<TICKET>/.<other-audit-id>/evidence-summary.json. Read them.

High-value confluences:

• depaudit + secaudit flag the same package → depaudit confirms it's present, secaudit confirms it's exploitable → CRITICAL, joint fix (the version bump closes both).
• depaudit + codeaudit both flag an unused/ghost dependency → confirmed dead weight, safe to remove.
• depaudit + perfaudit flag the same heavy client-bundle dependency → joint fix (remove/replace + tree-shake).

Mark such findings cross_audit_confirmed: true and bump severity one level.

PHASE 0b: SUPPLY-CHAIN CRIME SCENE SETUP

SESSION_ID="depaudit-$(date +%Y%m%d-%H%M%S)"
mkdir -p audits/.depaudit/{discovery,reports,sbom}
echo "AUDIT STARTED: $(date -Iseconds)" > audits/.depaudit/session.log

# ECOSYSTEM CENSUS — know exactly which supply chains exist
# (read-only discovery; the gather already populated the tree, this confirms the manifests)
for mf in package.json pnpm-workspace.yaml Cargo.toml pyproject.toml requirements.txt \
          go.mod Gemfile composer.json; do
  [ -f "$mf" ] && echo "MANIFEST: $mf" >> audits/.depaudit/session.log
done
for lf in package-lock.json pnpm-lock.yaml yarn.lock Cargo.lock poetry.lock go.sum; do
  [ -f "$lf" ] && echo "LOCKFILE: $lf" >> audits/.depaudit/session.log
done

Then read discovery/dependency-tree.json and compute the hinge package into discovery/hinge-package.json (deepest-imported × privilege × has-install-script).

PHASE 1: CVE EXPOSURE FORENSICS

"A known vulnerability is a published exploit with your name on the affected list."

1. ADVISORY RECONCILIATION (from evidence-summary.json, cross-ecosystem)
   For each CVE/GHSA/RUSTSEC/PYSEC advisory:
   → Which package, which installed version, which advisory ID?
   → Is it DIRECT or TRANSITIVE? (transitive = you can't just `npm i pkg@latest`)
   → What is the dependency PATH? (myapp > lib-a > lib-b > vulnerable-pkg)
   → Is a fixed version available? Is it a major bump (breaking)?
   → Severity (CVSS) + exploit maturity (PoC public? in-the-wild?)

2. FIX REACHABILITY
   → Direct dep → bump in manifest
   → Transitive via a maintained parent → bump the parent
   → Transitive via an abandoned parent → override/resolution pin, or replace the parent
   → No fix available → record as accepted-risk with justification + mitigation

3. CROSS-TOOL CONFIRMATION
   → Does more than one scanner (npm audit + osv-scanner) flag the same advisory?
   → Agreement = confidence high; disagreement = investigate (version range edge)

4. DEDUPLICATION
   → The same CVE may appear via N dependency paths. Count unique advisories, not raw rows.

FALSIFY: Don't trust the count. For each top advisory, run npm ls <pkg> (or cargo tree -i <pkg>) to PROVE the version is actually installed and find every path.

Severity: Critical/High advisory with a fix available and direct = CRITICAL. No fix + reachable = HIGH (accepted risk requires written justification).

PHASE 2: FRESHNESS & DRIFT

"Outdated isn't just old. It's the distance between the code you trust and the code that's been audited since."

1. VERSION LAG (from npm outdated / equivalent)
   For each direct dependency:
   → current vs wanted vs latest
   → How many MAJOR versions behind? (>2 major = upgrade debt, likely breaking)
   → How many MINOR/PATCH behind? (patch lag = missing security fixes)

2. RELEASE CADENCE
   → When was the installed version published? (npm view <pkg> time)
   → When was the latest published? Gap = how stale is your pin?
   → Is the project keeping pace with its own dependencies' release rhythm?

3. UPGRADE BLAST RADIUS
   → For each behind-by-major dep: what's the migration cost? (changelog severity)
   → Group: trivial patch bumps (do now) vs major migrations (plan separately)

4. SECURITY-RELEVANT LAG
   → Cross-reference Phase 1: is any outdated dep also CVE-affected?
   → A patch behind that closes a CVE = HIGH priority, not cosmetic.

PHASE 3: ABANDONMENT & MAINTENANCE RISK

"An unmaintained dependency is a CVE that hasn't been written yet, with nobody to fix it when it is."

1. ACTIVITY SIGNALS (per direct dep + the hinge package)
   → Last publish date (>18 months with no release = abandonment risk)
   → Last commit / last release on the source repo
   → Open-issue count vs response rate (issues pile up, no replies = dead)
   → Is it ARCHIVED on GitHub? Explicitly deprecated on the registry?

2. BUS FACTOR
   → Maintainer count (npm view <pkg> maintainers / crates.io owners)
   → Bus factor 1 = single point of human failure (illness, account loss, malice)
   → High download count + bus factor 1 + no recent release = the next incident

3. SUCCESSOR / FORK STATUS
   → Is there an official successor? (e.g. request → got/axios/undici, moment → dayjs/luxon)
   → Is the community fork the de-facto maintained version?
   → Is the dep deprecated-with-replacement on the registry?

4. CRITICALITY WEIGHTING
   → Abandoned leaf util used in one place = MEDIUM
   → Abandoned package on the hinge path = HIGH (its blast radius is the whole build/runtime)

FALSIFY: Before declaring "abandoned", check npm view <pkg> time.modified and the repo — a stable package with no recent release may be complete, not dead. Distinguish "finished" from "neglected" (does it still have unpatched CVEs? unanswered security issues? → neglected).

PHASE 4: LICENSE COMPLIANCE & CONTAMINATION

"A copyleft license deep in your transitive tree can legally compel you to open-source your proprietary product."

1. LICENSE CENSUS (from license-checker / cargo-license / pip-licenses)
   → Build the full license distribution: {MIT: 800, Apache-2.0: 200, ISC: 90, GPL-3.0: 1, ...}
   → Flag every COPYLEFT license: GPL, AGPL, LGPL, MPL, EUPL, CDDL, EPL
   → Flag every UNKNOWN / UNLICENSED / "SEE LICENSE IN" / missing license

2. COMPATIBILITY MATRIX
   → Determine the PROJECT's own license + distribution model (proprietary? OSS? SaaS?)
   → For each dependency license, is it compatible with that model?
   → AGPL anywhere + SaaS = contamination risk (the network-use clause)
   → GPL in a distributed binary = obligation to release source
   → "Custom" / non-OSI licenses = legal review required

3. ATTRIBUTION OBLIGATIONS
   → Which licenses require attribution / NOTICE files? (Apache-2.0, BSD, MIT)
   → Does the project ship the required attribution? (THIRD-PARTY-NOTICES, about page)
   → Missing required attribution = compliance gap even for permissive licenses

4. DUAL & CHANGED LICENSES
   → Any package that recently changed license? (e.g. Elastic, MongoDB SSPL, Terraform BSL)
   → Pinned to the last OSI-licensed version, or already on the restrictive one?
   → Dual-licensed deps: which license are you electing? Is it recorded?

5. DECLARED vs ACTUAL (Popper)
   → package.json says "MIT" — does the LICENSE file in the package actually say MIT?
   → Bundled/vendored sub-components with their own (different) licenses?

Severity: Strong copyleft (AGPL/GPL) incompatible with the distribution model = CRITICAL. Missing/unknown license on a shipped dep = HIGH. Missing attribution for permissive licenses = MEDIUM.

PHASE 5: LOCKFILE INTEGRITY & REPRODUCIBLE BUILDS

"No lockfile, no truth. A manually-edited lockfile, a lie with a timestamp."

1. LOCKFILE PRESENCE & SCOPE
   → Does a lockfile exist for EVERY ecosystem? (package-lock/pnpm-lock/yarn.lock, Cargo.lock, poetry.lock, go.sum)
   → Is it COMMITTED to git? (a gitignored lockfile = non-reproducible CI)
   → Library vs app: Cargo.lock for a library is debatable; for a binary/app it's mandatory.

2. MANIFEST ↔ LOCKFILE CONSISTENCY
   → Run the manager's verify mode: `npm ci --dry-run`, `pnpm install --frozen-lockfile --dry-run`,
     `cargo verify-project`, `poetry check`
   → Does the lockfile satisfy the manifest, or has the manifest drifted?
   → Are there manifest entries with NO lockfile resolution? (install was never run)

3. INTEGRITY HASHES
   → Does each lockfile entry carry an integrity hash (sha512 / checksum)?
   → Any entries WITHOUT integrity? (tarball could be swapped without detection)
   → npm: `"integrity"` present on every resolved package?

4. MANUAL-EDIT FORENSICS
   → git blame / git log the lockfile: was it ever hand-edited (not by the tool)?
   → A diff that changes a resolved version without a manifest change = suspicious
   → Resolved URL pointing at a non-canonical registry mirror?

5. REPRODUCIBILITY PROOF (Popper)
   → THE falsification: would `rm -rf node_modules && npm ci` produce the SAME tree?
   → If feasible in a scratch dir, do it and diff the resolved versions.
   → If not feasible, verify `--frozen-lockfile`/`npm ci` would succeed without modifying the lockfile.
   → A build that mutates its own lockfile during install is NOT reproducible.

Severity: No committed lockfile on an app = CRITICAL. Missing integrity hashes = HIGH. Drift between manifest and lockfile = HIGH. Hand-edited lockfile = HIGH (investigate intent).

PHASE 6: TRANSITIVE RESOLUTION & DEPTH

"You approved 40 packages. You installed 1,200. Who let in the other 1,160?"

1. TREE SHAPE
   → Direct count vs transitive count vs total unique packages
   → Maximum depth (A→B→C→...→Z): >7 levels = fragile, hard to reason about
   → Fan-out hotspots: which transitive packages are pulled by the MOST parents?

2. SINGLE POINTS OF SUPPLY FAILURE
   → A transitive package that, if compromised, lands in N% of the tree
   → Cross-reference with Phase 3 (abandonment) and Phase 8 (install scripts):
     deep + abandoned + has-postinstall = the hinge of maximum risk

3. PHANTOM / GHOST DEPENDENCY RECONCILIATION (from depcheck)
   → GHOST: `require`d/imported in code but NOT in any manifest (works only because a
     transitive dep happens to hoist it — breaks the day that transitive dep is removed)
   → PHANTOM: declared in manifest but never imported anywhere (dead weight, audit surface)
   → Reconcile manifest-vs-installed.json — every code import must trace to a DECLARED dep.

4. RESOLUTION OVERRIDES
   → Any `overrides` / `resolutions` / `[patch]` forcing a version?
   → Why? (usually to force a CVE fix into a transitive dep) — is it still needed?
   → Does the override actually take effect in the resolved tree? (verify with npm ls)

PHASE 7: TYPOSQUATTING, DEPENDENCY CONFUSION & NAMESPACE RISK

"crossenv is not cross-env. One of them mined cryptocurrency on install."

1. TYPOSQUAT DETECTION
   For every direct dependency name:
   → Levenshtein-distance-1 from a far-more-popular package? (reqeusts vs requests, loadash vs lodash)
   → Suspicious homoglyphs / hyphenation swaps (cross-env vs crossenv vs cross_env)
   → Recently published, low-download package with a name near a famous FLAG

2. DEPENDENCY CONFUSION (internal/private package risk)
   → Any scoped/internal package names (@company/foo) ALSO claimable on the public registry?
   → Is the package manager configured to prefer the public registry for those scopes? (the
     classic confusion attack — public version with a higher number wins)
   → Are private scopes pinned to a specific registry in .npmrc / .cargo/config / pip.conf?

3. NAMESPACE / OWNERSHIP TAKEOVER
   → Any dependency whose npm/crates owner recently changed?
   → Any dependency pointing at a git URL or tarball instead of the registry? (unverifiable provenance)
   → GitHub-installed deps (`user/repo`) with no commit pin = moving target

4. INSTALL-SOURCE TRUST
   → Are all deps installed from the canonical registry, or from mirrors/forks/CDNs?
   → Any `file:` / `link:` / `http(s):` tarball dependencies? (bypass registry integrity)

FALSIFY: For each typosquat suspicion, check npm view <suspect> downloads and publish date — a low-download, recently-published near-miss of a famous name is the strong signal; a legitimately-named low-download package is not. Don't flag every short name.

PHASE 8: INSTALL & LIFECYCLE SCRIPT AUDIT

"npm install is curl | bash with extra steps. Every postinstall script runs on your machine and your CI, with your tokens in the environment."

1. SCRIPT INVENTORY
   → Enumerate every dependency (direct + transitive) declaring a lifecycle script:
     preinstall, install, postinstall, prepare, prepublish (npm);
     build.rs (Cargo); setup.py exec (pip).
   → How many run on a fresh `npm ci`? (this is the actual code that executes on install)

2. SCRIPT CONTENT FORENSICS (read the actual script for flagged packages)
   → Does it download from the network? (curl/wget/fetch to a non-registry URL)
   → Does it read env vars / files outside the package dir? (token exfiltration shape)
   → Does it write outside its own directory? (filesystem tampering)
   → Does it spawn shells / eval dynamic strings?
   → Is the script obfuscated / minified / base64-encoded? (legitimate install scripts are readable)

3. PRIVILEGE & TRUST
   → Cross-reference with Phase 3/7: install script + abandoned/typosquat/low-trust = CRITICAL
   → Hinge-package install script = max scrutiny (read it line by line)

4. MITIGATION POSTURE
   → Could install scripts be disabled? (`npm ci --ignore-scripts` + explicit allowlist)
   → Is the project already using `--ignore-scripts` or a scripts allowlist?
   → For Cargo: are build.rs scripts from untrusted crates sandboxed/reviewed?

Severity: Network-fetching or env-reading postinstall on a low-trust/abandoned package = CRITICAL. Any unreviewed obfuscated install script = HIGH.

PHASE 9: VERSION POLICY (PINNED vs FLOATING)

"^ means 'I pre-approve code this maintainer hasn't written yet.' For production, that's a standing authorization you can't audit."

1. RANGE POLICY CENSUS
   → For each direct dep: exact pin (1.2.3) vs caret (^1.2.3) vs tilde (~1.2.3) vs wildcard (*/latest/x)?
   → Count: how many are floating? What proportion of the manifest?
   → `*` or `latest` or `>=` anywhere = unbounded trust = CRITICAL for a production app

2. APP vs LIBRARY EXPECTATION
   → APPLICATION: lockfile pins exact, manifest ranges are fine IF the lockfile is committed.
   → LIBRARY (published): ranges SHOULD be reasonably permissive (don't over-pin and create
     diamond conflicts downstream) but MUST avoid `*`.
   → Judge the policy against what the project IS.

3. CONSISTENCY
   → Is the pinning policy consistent, or ad-hoc per-dependency? (entropy signal)
   → Are dev vs prod dependencies pinned with different rigor? (prod should be at least as strict)

4. FLOATING-RANGE DRIFT RISK
   → Combined with Phase 5: a floating range + a committed lockfile = OK (lockfile pins reality).
   → A floating range + NO lockfile = the build is non-deterministic by design = CRITICAL.

PHASE 10: BLOAT & DUPLICATION

"You installed three versions of the same package, two utility libraries that do the same thing, and a 4MB dep to left-pad a string."

1. DUPLICATE VERSIONS
   → Same package present at multiple versions in the resolved tree (npm ls / dedupe report)
   → Each duplicate = wasted install size, larger bundle, divergent CVE exposure
   → Can `npm dedupe` / pnpm's stricter resolution collapse them?

2. REDUNDANT CAPABILITY
   → Multiple deps providing the SAME capability (axios + got + node-fetch + undici; moment + dayjs;
     lodash + ramda + underscore)
   → Each redundant lib = more surface, more to keep patched. Consolidate.

3. HEAVYWEIGHT FOR TRIVIAL USE
   → Large dependency used for one trivial function (a whole date lib for one format call;
     a kitchen-sink util for one helper)
   → Candidate for inlining a small helper or swapping to a focused micro-dep.

4. DEV-DEP LEAKAGE
   → Anything in `dependencies` that should be in `devDependencies`? (ships to prod/bundle needlessly)
   → Build/test tooling in prod deps = bloat + attack surface in the deployed artifact.

5. TREE-SHAKEABILITY (frontend)
   → CJS-only deps that defeat tree-shaking → entire library bundled even for one import.

Note: Bloat findings are mostly MEDIUM/LOW (hygiene), but a duplicate that pins a CVE-affected version alongside a fixed one escalates to HIGH (cross-ref Phase 1).

PHASE 11: REGISTRY TRUST & PROVENANCE

"Integrity proves the tarball wasn't tampered with in transit. Provenance proves it came from the source it claims."

1. PROVENANCE ATTESTATIONS
   → Do critical deps publish npm provenance / Sigstore attestations? (built from public CI, verifiable)
   → Cargo: crates from verified sources? Go: module checksums in sum DB?
   → Provenance present on the hinge package and high-privilege deps?

2. REGISTRY CONFIGURATION
   → Read .npmrc / .yarnrc / .cargo/config.toml / pip.conf
   → Which registries are configured? Any non-default mirror? Is it trusted?
   → Are private scopes correctly bound to the private registry (Phase 7 confusion defense)?
   → Any `registry=http://` (non-TLS)? Any auth token committed in a tracked .npmrc?

3. MAINTAINER ACCOUNT HYGIENE (best-effort, for hinge + high-privilege deps)
   → Maintainer count, account age signals, recent ownership transfers (Phase 3 overlap)
   → 2FA-on-publish enforced where the registry exposes it?

4. SUBRESOURCE INTEGRITY (CDN-loaded deps, frontend)
   → CDN <script>/<link> with integrity + crossorigin attributes?
   → SRI hashes present and current? Fallback if CDN compromised?

PHASE 12: BUNDLE EXPOSURE (server deps leaking to client)

"A server-only secret manager imported into a client component ships its API to every browser."

1. CLIENT BUNDLE COMPOSITION (frontend projects)
   → Build the frontend (or read an existing build report / analyzer output)
   → Which dependencies end up in the client bundle?
   → Any server-only package (db driver, secrets SDK, fs/crypto-heavy lib) in the client chunk?

2. SECRET / CONFIG LEAKAGE
   → Cross-ref /secaudit Phase 15: any dep embedding a secret that gets bundled?
   → NEXT_PUBLIC_/VITE_ exposure of values that came from a dependency's default config?

3. SIZE BUDGET
   → Heaviest deps in the bundle (cross-ref /perfaudit if available)
   → Any dep contributing disproportionate KB for marginal value? (Phase 10 overlap)

4. DUAL-PACKAGE HAZARD
   → ESM/CJS dual packages loaded twice (state duplication, larger bundle)?

Non-frontend project (CLI/library/backend-only)? Mark this phase N/A in the scoring and redistribute its weight per the preamble normalization rule. Do NOT fabricate findings.

PHASE 13: MONOREPO & WORKSPACE HYGIENE

"In a monorepo, one mispinned shared dependency is mispinned everywhere — or worse, pinned five different ways."

1. WORKSPACE TOPOLOGY
   → Detect workspaces (pnpm-workspace.yaml, package.json workspaces, Cargo workspace, Turbo/Nx)
   → Map internal package graph: which workspace packages depend on which?

2. VERSION CONSISTENCY ACROSS WORKSPACES
   → Is the same external dependency pinned to DIFFERENT versions in different packages?
   → Divergent versions = duplicate installs + inconsistent CVE exposure + bundle bloat
   → Is there a single-version policy (syncpack / pnpm catalog / Cargo workspace deps) enforced?

3. INTERNAL vs EXTERNAL BOUNDARIES
   → Are workspace-internal deps referenced via workspace protocol (workspace:*) not a published range?
   → Phantom hoisting: a package using a dep it doesn't declare because the monorepo root hoisted it?

4. ROOT vs PACKAGE DEPS
   → Dev tooling correctly at the root, runtime deps in the owning package?
   → Hoisting strategy (pnpm strict vs hoisted) understood and intentional?

Single-package project? Mark N/A, redistribute weight (preamble normalization).

PHASE 14: DEPRECATIONS & EOL RUNTIME

"A deprecation warning is a countdown. A package and a runtime both have expiry dates — and neither sends a reminder."

1. PACKAGE DEPRECATIONS
   → Registry-level deprecation messages on any installed package (npm shows "deprecated: ...")
   → Deprecated-with-replacement: is the migration tracked?
   → Deprecated APIs within deps you use (changelog / type deprecations)?

2. RUNTIME / ENGINE EOL
   → Declared engines (node, npm, python, rust msrv, go) — are any past EOL or near it?
   → Does a dependency require a newer engine than the project declares? (silent incompatibility)
   → `engines` field present and honored, or ignored?

3. PEER DEPENDENCY HEALTH
   → Unmet peer dependencies? (works today by luck, breaks on the next install)
   → Conflicting peer ranges across the tree?
   → Peer deps auto-installed (npm 7+) vs expected-but-absent?

4. PLATFORM / ABI DEPS
   → Native modules (node-gyp, prebuilt binaries) — supported on the deploy platform/arch?
   → Optional deps that fail silently on the target platform?

PHASE 15: REPRODUCIBILITY & BUILD INTEGRITY

"Reproducibility is the property that lets you trust every other finding. Without it, you audited a tree you'll never run again."

1. CLEAN-INSTALL DETERMINISM (Popper, the keystone test)
   → In a scratch directory (NEVER the working tree), attempt a frozen install:
     `npm ci` / `pnpm install --frozen-lockfile` / `yarn install --immutable` /
     `cargo build --locked` / `poetry install --no-update`
   → Does it succeed WITHOUT mutating the lockfile? (mutation = non-reproducible)
   → Diff the resolved versions against the committed lockfile — any drift = finding.

2. CI vs LOCAL PARITY
   → Does CI use the frozen/locked install command, or a loose `npm install`?
   → A CI that runs `npm install` (not `npm ci`) can silently resolve different versions than dev.

3. POST-INSTALL ARTIFACT INTEGRITY
   → Generated artifacts (patches via patch-package, prebuilt binaries) checked into git with hashes?
   → Any `patch-package` patches — do they still apply cleanly? Are they reviewed?

4. SBOM ↔ TREE PARITY
   → Does the generated SBOM (Phase 16) match the actually-resolved tree exactly?
   → A drifted SBOM describes phantom software — useless for incident response.

SAFETY: all reproducibility tests run in a throwaway scratch dir or --dry-run mode. NEVER mutate the project's node_modules, lockfile, or target/ during the audit phase.

PHASE 16: SBOM GENERATION & COMPLETENESS

"When the next supply-chain incident drops, the only question that matters is 'are we affected?' An SBOM answers it in seconds. No SBOM answers it in days."

1. SBOM GENERATION
   → Produce a complete CycloneDX SBOM (sbom/sbom.cyclonedx.json) AND an SPDX alternative
     (sbom/sbom.spdx.json) covering EVERY ecosystem present.
   → One unified SBOM if multi-ecosystem, or one per ecosystem, clearly scoped.

2. COMPLETENESS CHECK
   → Component count in SBOM == unique packages in the resolved tree? (parity, Phase 15.4)
   → Each component carries: name, version, PURL (package URL), license, hashes, supplier.
   → Any component missing a license or hash = incomplete SBOM = finding.

3. VULNERABILITY-LINKED SBOM
   → Annotate (or cross-link) the SBOM with the Phase 1 CVE findings (VEX-style).
   → The SBOM should be a queryable source of truth for "do we use package X?".

4. MAINTENANCE POSTURE
   → Is SBOM generation wired into CI (regenerated on every dependency change)?
   → Or is this audit the first SBOM the project has ever had? (recommend CI integration)

Deliverable: audits/.depaudit/sbom/sbom.cyclonedx.json is a primary artifact of every full run.

PHASE H1 — HYBRID SYNTHESIS (Popper / hinge / user-need / edge cases / cross-audit)

Runs immediately before VERDICT. "H1" does NOT renumber existing phases — it sits between the last domain phase and the verdict, and REINVESTS the token budget freed by Phase 0's deterministic gather into depth. It deepens earlier phases; it replaces none.

H1.1 Popper falsification per finding (mandatory)

For every finding (start with severity ∈ {critical, high}), try to PROVE the tool wrong. Each falsification produces a falsifiable_tests[] entry in verdict.json:

{
  "claim": "osv-scanner says lodash@4.17.11 is vulnerable to CVE-2019-10744 (prototype pollution)",
  "test_command": "npm ls lodash --all",
  "expected": "lodash@4.17.11 present in the resolved tree → claim TRUE",
  "actual": "myapp > some-lib > lodash@4.17.11 (1 path)",
  "outcome": "confirmed"
}

Outcomes: confirmed (test failed to falsify → finding stands), falsified (counter-example → demote to info + record falsified_at), inconclusive (couldn't run cleanly → keep severity, confidence: medium).

The rule: every CLAIM (PASS or FAIL) MUST cite ≥3 concrete commands that COULD have falsified it but didn't. Banned phrases (looks correct, should be fine, appears to work) → automatic FAIL.

Common falsification patterns for THIS domain:

H1.2 Hinge cross-reference (10× scrutiny on the load-bearing dependency)

The SUPPLY-CHAIN HINGE POINT (discovery/hinge-package.json) is the dependency of maximum blast radius. Apply 10× scrutiny:

• 5× more falsification attempts (H1.1) on findings touching it
• Read its install scripts line-by-line (Phase 8), its license file (Phase 4), its maintainer set (Phase 11)
• Trace EVERY dependency path that reaches it (npm ls <hinge> / cargo tree -i)
• Mark each such finding is_load_bearing: true and emit hinge_findings[] in verdict.json.

H1.3 User-need verification (--user-need quote)
