Follow-up to #430. That PR fixed the urgent findings from a supply-chain audit and wrote the rest down. This fixes the rest.

They turned out to be the same bug in nine places: a check that passes without checking anything. Each one below has a reproduction, and reverting the fix makes a specific test fail.

What was broken

Horizon app id — an example could ship without the id and still pass. The audit matched the meta-data name as a substring, so com.example.<the real name> counted. The Expo check accepted a horizon block anywhere in the file, even a local variable the build never reads; it now parses the config and follows android.horizon.appId through object literals and const bindings, reporting anything it cannot read rather than guessing. The merged-manifest check looked at the whole document, so an id nested in an <activity> passed even though Horizon only reads it from <application>. Without the id, startConnection throws on a headset.

Published metadata read as "no dependencies" — the NuGet and Maven readers accepted any HTTP 200 body. An error page or a truncated response became a package that declares nothing, and the SBOM shipped incomplete.

SBOM coverage gaps — the old check only looked at the newest release per component, so a gap behind it was permanent. The new one covers every release since a component started publishing SBOMs. It also refuses a release list that is missing a component entirely, instead of skipping it.

Licences that were guessed — Maven took the first licence name it found, silently picking one when a POM declared two. Maven defines several licences as alternatives the user may select, so they now become an SPDX OR expression — and only when every operand is a recognised identifier.

Audits that could be satisfied by the wrong thing — the Bun runtime version was read from anywhere in the Dockerfile, so a comment satisfied it. The Godot binary check decided what to protect by reading each file's own bytes, so replacing an executable with junk removed it from the scan.

A deploy that proved nothingflyctl deploy was the last line of the workflow. It now reads /health back and requires the serving revision to be the commit just built.

CodeQL scanning released code — one import pulled ~18,700 lines of shipped Apple code into the database, producing alerts no PR could fix.

Data we were fetching and discarding

pub.dev states licences as score tags, and we were returning null under a comment saying it had none. The Flutter SBOM goes from 7/10 to 10/10 on licence and supplier coverage. NuGet <copyright> was never read; 22 of 24 MAUI components now carry one.

Nothing is inferred. Every value comes from something the registry actually states.

Wording we corrected

  • The sign-in modal said IAPKit handles "tax compliance". It doesn't calculate, file, or remit tax. Now: "Verify purchases and manage entitlements".
  • Release tags were called immutable. That's true of what npm provenance binds to, not of anything enforced here.
  • The Horizon check can't prove an app id is registered with Meta, and two columns of the SBOM table aren't machine-checked. Both docs now say so.

Not done, on purpose

Gradle dependency locking (churn exceeds value), a container SBOM for IAPKit (Fly builds remotely, so it wouldn't describe the real image), immutable releases (SBOMs attach after the release exists), and byte verification for Maven/pub.dev/NuGet (needs a live publish).

Checks

node --test scripts/*.test.mjs — 429 passed. Plus audit:parity, audit:docs, audit:sbom-docs, audit:facts, audit:layout, audit:ci-paths, audit:horizon-app-id, audit:godot-binaries, sbom:test.

Reviewed by Grok and Codex before merge; every finding either fixed here or answered.

🤖 Generated with Claude Code

#430 checked that every example declares the Horizon meta-data, and verified
what the build resolves it to for packages/google only. The Flutter example
resolves its id through the same kind of Gradle placeholder and had no such
check, because that workflow built no Android variant — the one gap #430
recorded rather than closed.

The Analyze & Test job already builds Android for the consumer smoke test, so
this adds a step rather than a job. Merging the manifest is enough; no APK is
built.

Verified both directions against a real Gradle run:

  fixed    → Horizon app id resolves in .../merged_manifests/debug/...
  reverted → FAIL the Horizon app id merged as empty, so startConnection
             will throw

security/README.md now lists both targets instead of describing Flutter as
unverified, and the audit's own comment says the same.

📝 Walkthrough

Walkthrough

CI now verifies the Flutter example’s resolved Horizon app id in the merged Android manifest. SBOM generation adds coverage-gap detection, metadata enrichment, and stricter metadata parsing. Security workflows and documentation define related controls. Toolchain, deployment, retry, and modal-copy changes are also included.

Changes

Horizon manifest verification

Layer / File(s) Summary
Merged-manifest CI check
.github/workflows/ci-flutter-inapp-purchase.yml, scripts/audit-horizon-example-app-id.mjs
The workflow runs processDebugManifest with Horizon enabled and validates the merged manifest. Audit documentation describes CI coverage for templated-manifest targets.

SBOM and security controls

Layer / File(s) Summary
SBOM coverage and metadata generation
scripts/generate-sbom.mjs, scripts/sbom-dependencies.mjs, scripts/generate-sbom.test.mjs
SBOM generation defines coverage floors, reports missing stable-release assets, validates NuGet documents, parses Trivy exceptions, enriches NuGet and pub.dev metadata, and tests these behaviors.
SBOM audit and CI enforcement
.github/workflows/security-rescan.yml, scripts/audit-sbom-docs.mjs, scripts/audit-sbom-docs.test.mjs, scripts/generate-sbom.test.mjs, security/SBOM.md
CI fails when required SBOM assets are missing. Component-table parsing is scoped to its table. Tests validate coverage, parser rejection, Trivy exception structure, and dependency consistency. Documentation defines coverage and pub.dev handling.
Security review register
security/dependency-reviews.md, security/ASSURANCE.md, security/openchain.md
The dependency review register records policy triggers, review scope, entries, and cadence. Assurance and OpenChain documentation reference the register and package-license coverage.

Toolchain and deployment controls

Layer / File(s) Summary
Bun toolchain declarations
scripts/facts.mjs, scripts/audit-facts.mjs
Declared facts distinguish pinned and runtime-image Bun roles. Fact auditing checks each declared value against its scanner role.
Deployment and analysis controls
.github/workflows/codeql.yml, .github/workflows/deploy-kit.yml, scripts/audit-security.mjs, scripts/audit-security.test.mjs
The KMP Swift bridge builds after CodeQL analysis. Deployment revision checks handle retryable health responses. Bun auditing uses four attempts with exponential backoff, with tests for retry behavior.

Auth modal copy

Layer / File(s) Summary
Sign-in modal subtitle
packages/kit/src/components/AuthModal/index.tsx
The subtitle changes to “Verify purchases and manage entitlements.”

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 52038

Malformed NuGet metadata can still produce an incomplete SBOM that omits dependencies, weakening supply-chain inventory accuracy. The new Bun retry path also lacks regression coverage for its final retry and backoff schedule. These issues should be corrected before merge.

…y state

Three registry facts were fetched or reachable and then thrown away.

pub.dev licences. The generator returned null for every `pkg:pub/` component
under a comment asserting that "pub.dev has no standard license field in
package metadata". That is not true: the documented `/api/packages/<name>/score`
endpoint carries the licence as a tag. All three Dart dependencies of the
Flutter SBOM had no licence and no supplier as a result; they now resolve to
BSD-3-Clause / dart.dev, taking that SBOM from 7/10 to 10/10 on both.

Only tags that resolve to a known SPDX id are kept, so pub.dev's classification
tags (osi-approved, fsf-libre) drop out without needing a list of tags to
ignore, and a package declaring two different licences yields none rather than
a coin flip. security/SBOM.md loses the false claim and gains the real caveat:
pub.dev scores the version it last analysed, while the SBOM records a
constraint, because Dart lockfiles are not committed.

NuGet copyright. `<copyright>` was never parsed. It is stated, unambiguous, and
the one datum a NOTICE file needs that a licence identifier does not supply.
22 of the 24 MAUI components now carry one.

NuGet licence URLs. A `<licenseUrl>` that maps to no SPDX id was dropped
entirely; it is now recorded as `license.url`, which says where the terms are
without asserting which they are. The exception is NuGet's own
`aka.ms/deprecateLicenseUrl` placeholder, which states nothing and would be a
fabricated citation — `Xamarin.Android.Google.BillingClient` carries exactly
that, and still resolves to no licence, correctly.

Nothing here infers a licence. Every value is one the registry states.

findMissingLatestSbomTags reports at most one release per component: it pushes
a tag only after `seen.has(componentId)` has been checked, so once a newer
release ships, a missing SBOM behind it can never be reported again. Proven
against the real release list — stripping the SBOM asset from godot-iap-3.4.0
while 3.5.0 still has one leaves that scan empty.

findMissingCoverageTags reports every stable release from the point its
component started publishing SBOMs. On the same mutated input it returns
["godot-iap-3.4.0"]. On the real list it returns nothing: 419 stable releases,
59 inside the coverage era, no gaps.

The floors are derived from the published releases, not chosen — each is the
first release of that component that actually carries an SBOM. A component with
no entry is required from its first release, which is what keeps a component
added later covered without anyone remembering to extend the table.
`commerce-protocol` and `conformance` need no entry for that reason.

Two fail-closed properties: a floor tag absent from a release list that does
contain that component is an error, so a truncated page cannot narrow the scan
in silence; and a component the list never mentions is out of scope rather than
silently passed.

security/SBOM.md gains the policy this implies — where the boundary is, what is
enforced, why pre-floor releases are not backfilled (an SBOM generated today
resolves today's metadata and would describe something other than what shipped),
and when a backfill is nonetheless appropriate.

Also fixes audit-sbom-docs, which matched a backticked identifier in any table
and so read the new coverage table as a component matrix. It now anchors to the
component table's own header; reverting that makes it report the document
against itself.

`toolchain.bun` scanned the workflows and package.json, both of which say
1.3.13. It did not scan packages/kit/Dockerfile, which says 1.4.0 — and since
IAPKit deploys with `flyctl deploy --remote-only`, that Dockerfile's Bun is what
compiles the binary serving traffic. The version gating the deploy and the
version producing the artifact were different, and the audit built to catch
exactly this kind of drift could not see one of them.

The Dockerfile is now scanned and both roles are declared, so neither can move
silently. Bumping the container Bun without declaring it fails with the site and
both values named; removing the scanner fails because the declared runtimeImage
no longer occurs.

The gap itself is left as it is and written down in security/README.md rather
than closed here — agreeing one version and moving both together is a decision,
not a cleanup.

ASSURANCE.md requires explicit maintainer review before a dependency with
custom terms or no license enters a released artifact, and commits to reviewing
that policy at least every six months. Neither had anywhere to be recorded, so
an outstanding review was indistinguishable from a completed one.

security/dependency-reviews.md derives the trigger set from the published SBOMs
rather than curating it: nine dependencies, being five Meta Horizon SDK modules,
two Google SDK modules, one Amazon SDK module, and
Xamarin.Android.Google.BillingClient, which declares no license at all. Twenty-
one dependencies carrying a compound SPDX expression such as `MIT AND
Apache-2.0` are excluded, because that is valid SPDX and not a trigger. Every
row is unreviewed and says so; the register records no review that has not
happened.

The OpenChain per-package LICENSE row is updated rather than reworded: every
currently published package now carries licence text in its tarball, including
openiap-conformance from 2.0.0, verified by unpacking each. It stays Partial
because 1.0.0 and 1.0.1 remain downloadable without one.

Also records two things the docs assumed. Release tags are called immutable in
the git-deployment guide, which is true of what npm provenance binds to and not
of any enforced protection — this repository has no rulesets and no branch
protection on main. And Dart lockfiles are absent on purpose, because a
published package must not pin what its consumers resolve; that is why the
Flutter SBOM records a constraint rather than a version.

The sign-in modal read "Manage your in-app purchases and tax compliance".
IAPKit stores a Stripe tax id for its own invoicing and preserves the tax
settings a Play buy option carries, but it does not calculate, file, or remit
tax for anyone. In a regulated area that is a claim a reader can act on.

It now says what the product says of itself everywhere else — "Open purchase &
entitlement infrastructure" on the landing page, "Purchase validation +
entitlement infrastructure" in the repository guide.

Nothing else changed. The remaining occurrences of "tax" are accurate: the docs
tell developers to complete their own store's tax forms, the purchase type
documents tax fields the store returns, and the organization settings collect a
tax id for IAPKit's billing.

The Swift analysis job built the KMP Swift bridge between init and analyze, so
the bridge's dependencies went into the CodeQL database. Its whole source is:

  @_exported import OpenIAP

and its Package.swift pins openiap to a released tag, so that one line dragged
57 files and roughly 18,700 lines of a previous release of packages/apple into
the same database the working tree had already been extracted into.

The duplication cost build time on a 45-minute macOS budget, but the sharper
problem is attribution: an alert raised against the released copy names code no
pull request can change, because the fix only reaches it when the version pin
is bumped.

The build now runs after the analyze step, so it still compiles — nothing else
in CI compiles this package, and the build is what proves the manifest still
resolves — while contributing nothing to the database. The path filter still
selects the job when the bridge changes, for the same reason.

The previous commit's prose described an earlier revision of the change, where
the bridge build was removed outright. It is compiled — after the analysis step,
so it is checked without entering the database — because nothing else in CI
compiles that package.

…contract

The Trivy guard asserted the current exception's text — its CVE id, its purl,
its expiry date. That pins a snapshot rather than a policy: removing an
exception that had properly expired would fail the test, and a new exception
could be added with no expiry and no statement without failing anything.

It now checks the properties that matter. Every exception must name an
advisory, name the packages it applies to, carry an expiry date, still be
within it, and explain itself. The messages are the instruction:

  CVE-2026-14456 expired on 2026-08-01: recheck the vendor classification
  or remove it
  CVE-2026-14456 has no expiry date, so it would never be rechecked

Each of the four is mutation-proved. The current exception expires
2026-09-14, so this starts failing on the 15th unless it is rechecked or
removed, which is the whole point of an expiry.

Separately, GodotIap.gdap is now cross-checked against the godot SBOM.
The .gdap is what a consumer's Gradle resolves and the SBOM is what the release
tells an auditor it ships; both derive from the same version sources but by
different code, so nothing stopped them diverging. Changing either a version or
the dependency list in one fails the test.

fetchText returns any 200 body, and parseNugetNuspec treated a document with no
<dependencies> block as a package that declares none. An error page, a CDN
placeholder, or a truncated response therefore produced an empty dependency
list rather than a failure.

The workflow's "SBOM declares no exact third-party components" gate does not
catch it. maui's source is an aggregate of the nuspec and the openiap native
packages, so the native half keeps the component list non-empty while the
NuGet half is silently gone.

A nuspec always has <package> and <metadata>. Without them the document is not
a nuspec and now raises PublishedMetadataUnavailableError, which the generator
already knows how to surface. A real nuspec with no dependencies block still
means none.

The existing parser fixtures omitted <metadata>, so they were not shaped like
the documents they stand in for; they are corrected rather than exempted. The
real MAUI SBOM is unchanged at 24 dependencies.

`flyctl deploy` was the last line of the workflow. Everything before it proves
what was built and pushed; nothing proved what ended up serving.

The pieces were already there and unused: the image bakes IAPKIT_REVISION as a
build arg and an OCI label, and /health reports its first twelve characters.
The deploy now reads that back and requires it to match, retrying while the
rollout settles. A deploy that reports success without replacing the machine
fails here instead of passing silently.

Checked against the live service, which reports 42f3551 — the merge commit
currently on main — so the comparison is exercised, not assumed.

Three findings from a Grok review of this branch.

The SBOM coverage floor compared publish timestamps while the documented rule
is a version. Releases are not published in version order — a patch on an older
line lands after a newer minor, and recreating a release moves its timestamp —
so the check was wrong in both directions, and both reproduce:

  3.4.0 published before the 3.3.0 floor  → exempted, though it is above it
  3.2.1 published after  the 3.3.0 floor  → reported, though it is below it

It now compares versions with the existing compareSemVer. The real release list
still reports no gaps.

The post-deploy health check did not retry. Under the Actions shell's
`set -eo pipefail`, a 200 response whose body is not JSON made jq fail and
ended the step on the first attempt, before any retry and before the
diagnostic. Both fetch and parse are now tolerated per attempt, and the
comparison lowercases the served value as well as the expected one.

Its comment also overstated what it proves. A single public GET reaches one
instance, so it catches a deploy that replaced nothing — not a partial rollout
across machines. It now says that.

The nuspec gate required <package> and <metadata> but not the closing tag, so a
response truncated mid-document still read as a package declaring no
dependencies. That was the narrowed form of the bug it was added to fix.

…junk

Four findings from CodeRabbit, each reproduced first.

Declaring two roles for toolchain.bun did not stop them swapping. The audit
checked that every occurrence was one of the allowed values and that every
value still occurred somewhere, so putting 1.3.13 in the Dockerfile and 1.4.0
in the workflows passed while both roles were wrong. A scanner may now claim a
role, and an occurrence from it must equal that role's value:

  toolchain.bun: .github/workflows/ci.yml:80 declares "1.4.0" but that site
  carries the pinned role, which is "1.3.13"

Scanners without a role keep the previous behaviour, so nothing else changes.

The pub.dev lookup parsed the publisher response inside the same try as the
score response, so a malformed publisher body threw into the outer catch and
discarded a licence the score document had already stated. It is parsed
independently now.

The Trivy exception guard accepted "CVE-invalid" as an advisory id and
"2026-99-99" as an expiry — and the latter also satisfied the lexical
comparison, so such an exception would never expire. The id must now match a
real CVE or GHSA shape, and the date must round-trip through Date, which also
rejects 2026-02-30.

The dependency review register claimed more than it covered. ASSURANCE.md names
five triggers and the register derives one of them. The other four have no
derived source — each needs its own signal, and none is inferable from an SBOM
— so they are listed as untracked rather than left to be assumed covered.

sbom.yml runs the current generator against a released tag's tree by copying
the generator files in by name. `xml-document.mjs` was not on that list, so
every historical release failed with ERR_MODULE_NOT_FOUND before producing an
SBOM — reproduced against godot-iap-3.5.0. Add it to the checkout and the path
filter, and derive a test from the entry point's import graph so the next
module cannot be forgotten.

Four readers accepted input they should refuse. CDATA outside the root element
was ignored, so an error page prefixed to a real document passed as metadata.
The Trivy reader skipped any entry shape it did not recognise, which returned
no exceptions at all and made every lifecycle check below it vacuous; it now
refuses. A coverage floor naming another component's tag satisfied the presence
check while its own component had no release in the list. The Expo inspector
matched `horizon` anywhere under `android`, so `android.decoy.horizon.appId`
passed even though the plugin reads the direct path; property lookups now walk
brace depth.

The Maven reader still scanned raw XML after the parser landed, so it counted
dependencies inside comments and matched only the exact opening tag. The
published httpmime 4.5.6 POM carries a commented-out dependency with no
version, and our reader threw `Incomplete runtime dependency` on it — a
document Maven Central actually serves. Licence enrichment had the same shape:
it recorded MIT from a comment, and from a `<project>` nested inside an error
page. Both now read the parsed tree.

Three Horizon fixes. The tools namespace is honoured under whatever prefix the
document binds to it, so `t:node="remove"` is no longer missed. A commented-out
plugin entry no longer supplies options. And `{android: {horizon}}` shorthand
resolves its binding — that legitimate config was being reported as missing the
app id, which is worse than the bypasses it was guarding against.

Documentation: Google resolves a published POM like KMP and MAUI, not committed
manifests. The Xamarin BillingClient example was backwards — its licenceUrl is
NuGet's deprecated placeholder, which we drop, and its `<license>` names a file
rather than an expression, so it resolves to no licence at all. The
component-completeness error now names its remedy, and SBOM.md states the cost:
a component added before its first release fails the check until it ships.

The security README republishes both Bun versions and security/SBOM.md
republishes the coverage floors. Neither copy was audited, so either could go
stale while every check passed. Both are now compared with the values the code
uses, in both directions: a wrong copy fails, and a floor added to the
generator without the table fails too.

Mirrors are marked as such. A scanner that only republishes a fact must agree
with the registry, but it must not satisfy the "this value still occurs"
requirement — otherwise adding the README table would have made deleting the
Dockerfile's `FROM oven/bun:` line invisible, which it briefly did.

Three smaller guards. The manual/rescan parity extractor joins backslash
continuations, so a command wrapped across lines still counts as a gate. Godot
Mach-O detection recognises 64-bit universal archives, so a binary disguised
under an excused name is not excused by its magic. The KMP bridge guard reads
the target path from Package.swift rather than assuming `Sources/`.

Documentation: security/README.md and security/ASSURANCE.md still described
newest-release SBOM coverage, which the coverage floor replaced; and SBOM.md
named a `versionRange` field the generator does not emit.

The tokenizer accepted documents no XML parser should. A repeated attribute
silently overwrote the first, so `id="A" id="B"` read as B; an undeclared
entity, a bare `&`, a raw `<` inside an attribute value, a comment containing
`--`, and `]]>` in character data all passed. All are rejected now, and the
predefined entities and numeric references still decode. Real nuget.org and
Maven Central documents still parse: MAUI 22 dependencies, BillingClient 10,
httpmime 1.

That made `maskXmlComments` redundant, so it is gone. One behaviour changes
with it: a stray `-->` in character data is no longer treated as malformed,
because XML excludes only `]]>` there. The document genuinely declares that
dependency, and the old masker was rejecting a well-formed body.

The nuspec licence, supplier and copyright are read from the metadata element
rather than the raw text. A commented-out `<copyright>` before the real one was
recorded as the artifact's attribution, which would have published a false
statement in the SBOM.

Expo: a shorthand `horizon` had to be a direct member of `android`, and a
binding must be visible from where it is referenced. `{android: {experimental:
{horizon}}}` passed, and a same-named constant inside an unrelated function
stood in for the object the plugin actually receives. Both are rejected now,
and the real config — which declares its options inside the exported function —
still passes.

`tools:node="removeAll"` deletes the declaration as surely as `remove`.

Two guards were narrower than they read. A mirror scanner that matches nothing
now fails, so deleting or reformatting the README's Bun rows is caught rather
than passing because another site still carries the value. The release-tree
import test recognises `import "./x"` and dynamic `import()` as well as
`from "./x"`, and sbom.yml's path filter lists the whole restored closure.

npm cannot register a trusted publisher for a package that does not exist, so
the name was claimed by publishing 0.0.0-bootstrap.0 once by hand. That version
carries no attestations and sits on the `bootstrap` dist-tag while `latest` is
0.1.0, the first provenance-verified release. Someone auditing the registry
will find a version without provenance and needs to know it is a namespace
placeholder rather than a release that escaped the lane — the same footnote
openiap-conformance@1.0.0 already carries.

…spreads

CycloneDX requires a licence object to carry an id or a name, so the
`{license: {url}}` shape this branch introduced would have failed the schema
validation sbom.yml runs after `--with-licenses` — a release-blocking defect,
not a cosmetic one. A licence known only by its URL now travels as an
`externalReferences` entry of type `license`, which is where CycloneDX puts it.

Lookup results also stopped carrying explicitly-undefined keys, since callers
deep-compare them and an absent key is not the same shape as an undefined one.

`&#65A;` was accepted and truncated to `A`: the entity pattern allowed hex
digits in a decimal reference. Decimal and hexadecimal forms are separate now.

Three more places asserted more than they knew. A binding had to be declared
before the reference, not merely inside a scope that ends after it, so a
same-named constant in a later block could shadow the object the plugin
receives. A spread into `android` can replace a key after it was read, so the
audit reports that it cannot resolve the value rather than trusting the
literal. And a duplicate `<dependencies>` or `<metadata>` container is refused
instead of read half-way, which had silently dropped everything the second one
declared.

Removed the dead comment stripper, its regex constants, an unused local, and
`xmlValue` — the parser replaced all of them.

The commerce-protocol footnote now says what the registry proves: the
placeholder is installable but not a project release, it was published outside
the CI lane, `0.1.0` carries both npm publish and SLSA provenance, and
dist-tags are mutable while attestations are not.

Codex ran 1,068 published POMs and 430 nuspecs through the parser and none were
rejected.

…rove

Five branches decided whether CI blocks a Horizon build and none was
exercised: a merged manifest that is not well-formed, a self-closing
`<manifest/>`, a matching meta-data with no `android:value`, and the static
inspector's unreadable-source and missing-`<application>` paths.

The Expo audit reads the options object the plugin entry names, but the real
config assembles its `plugins` array through a binding and pushes to it
conditionally. Following that would mean evaluating the module rather than
reading it, so a tuple left behind while the exported array is emptied still
passes. That is a refactor accident this audit does not catch, and pretending
otherwise is worse than saying so: the code and the security README now state
the boundary, and point at the merged-manifest verifier as the check that
proves what a build actually resolves.

…eading

CycloneDX types externalReferences.url as an iri-reference, so a registry value
carrying whitespace fails whole-document schema validation at release time —
Codex reproduced it against a complete generated MAUI document. A URL that is
not a usable IRI is dropped now: the licence was already absent, and an invalid
reference blocks the release.

The spread guard was too broad. A spread AFTER the key replaces it, but one
BEFORE it loses to the later explicit property, and that ordering is decidable
without evaluating the module. Rejecting both blocked a correct config, which
is worse than the bypass it was added for.

The binding matcher let `[^=]*` cross a statement boundary, so `let options;`
followed by `const metadata = {` matched as one declaration and an unrelated
object stood in for the plugin's options. Only a type annotation may sit
between the name and its `=`.

security/SBOM.md still described the licence URL as `license.url`. Removed the
six XML regex constants the parser replaced.

Found by Codex in pre-merge review.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Dropping an unusable licence URL removed the declaration entirely, so a POM
declaring MIT alongside a second licence with a malformed URL collapsed to a
bare MIT claim. An unusable URL still counts as a declaration now; it is simply
not recorded as a reference. Codex measured the filter against 1,410 real
declared URLs across 1,492 published documents and it discards none of them.

Three guards rejected correct work. A spread before a shorthand `horizon` was
reported unsafe because only `horizon: …` counted as the key. An object-shaped
type annotation made the binding unreadable, so a valid config looked like it
passed no options. And a component merged before its first release could not
satisfy the coverage audit at all — no releases to find, no floor tag to name —
so `UNRELEASED_COMPONENTS` is now the explicit, reviewable way to say "not
shipped yet", and the error names it.

Three guards asserted more than they knew. A spread after any verified property
replaces it, at the options, android and horizon levels alike, not only
directly inside android. A processing instruction was skipped without checking
it has a target or that an XML declaration sits at the start. And a fact whose
scanners all name their roles now requires each role to be observed through a
scanner carrying it, so two roles converging on one version no longer lets a
single occurrence satisfy both.

The Godot manifest renderer enumerated only Mach-O files while the audit
required a digest for every non-excused file, so an ordinary framework resource
could be neither recorded nor excused. Duplicate rows in the SBOM coverage
tables are reported instead of silently overriding each other.

The digest fixtures copied the whole 8 GB addon three times per run to read a
manifest and one directory; they stage only those now, and the suite finishes in
under half a second.

security/dependency-reviews.md claimed its tracked set is derived. Nothing
regenerates or checks it, so it now says so.

Found by Codex in pre-merge review.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The Godot digest writer and its verifier disagreed. `--write` recorded every
file needing a digest, but collection still enumerated only Mach-O, so a
recorded framework resource came back as "no longer exists" and the documented
recovery command could not produce a manifest the audit accepts. Both sides use
the same set now: adding a PrivacyInfo.xcprivacy is reported, `--write` clears
it, and tampering with it afterwards is caught.

The XML reader skipped any `<!Name …>`, so `<!garbage>` inside the root and a
DOCTYPE after it both parsed as well-formed — and the POM and nuspec readers
treat that success as structural validation. A declaration must now be a
DOCTYPE, before the root. Maven Central serves POMs with one, and those still
parse.

A `<dependencies>` container below a wrapper outside `<metadata>`, such as
`<files><dependencies>…</dependencies></files>`, is well-formed XML that a
direct-child check does not see, so it read as a package declaring none. Every
descendant container is checked now.

The KMP bridge guard walked only `.swift`. SwiftPM builds C, Objective-C and C++
sources in the same target with no explicit path, and this package is built
after CodeQL analyses, so those would ship unanalysed. Adding a `.c` file to the
bridge now fails the guard.

The Expo Horizon audit walked brace depth wrong for the key it had just
matched: it resumed past that key's own `{`, so everything inside
`horizon: {…}` counted as a direct member of android and the closing brace
drove depth negative. `{android: {horizon: {horizon: {appId}}}}` passed on
the nested decoy.

The spread rule that reads what a spread carries only recognised `key: {`,
so a source spreading `{appId: ""}` looked like it declared nothing and the
overwrite it performs went unreported. It now asks whether the key is
declared in any value shape, and skips the name used as a value.

Under two declared licences the Maven reader recorded one of their URLs as
an external reference of type `license`. That reads as the component's
licence, so it answered a question the document leaves open. It records
nothing when the terms are ambiguous.

Anchors every released component to a coverage floor. "Covered from its
first release" cannot be proved from a release list that might be missing
that release. Also: a byte-order mark no longer pushes `<?xml` off offset
zero, `<?xml?>` without a version is not a declaration, and duplicate rows
in the SBOM component matrix are reported instead of silently overriding.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Nothing ran this audit. `security/README.md` listed it among the enforced
checks, but no workflow and no hook invoked it, so five rounds of review
hardened a guard that gated nothing. It now runs in CI and in the
pre-commit hook, and a test asserts both — including that the hook's path
filter matches every file the audit reads.

Wiring it up exposed what it was doing. It tried to resolve what a config
would evaluate to — spreads, ternaries, bindings, reassignment — and each
review round found another shape that slipped past or was wrongly refused.
Six more this round: a ternary arm read as its first token, a quoted key
invisible because the masker blanks strings with their quotes, a
reassigned binding read at its declaration, and three ordinary shapes
reported for no reason.

That is evaluation, not reading, and the input does not need it: a fixed
list of six files this repository owns, one of them an Expo config. So the
reader models one shape — plain object literals, plain keys, a literal id
— and reports anything else with "write the Horizon app id as a plain
literal". Reporting a shape we cannot read is honest; guessing is how an
unverified app id ships looking verified.

Smaller as a result: 371 lines changed to 147, with the spread resolver,
the depth walkers and the shorthand scanners gone.

A POM listing two licences produced no licence at all. Maven's model
descriptor settles what the pair means — "If multiple licenses are listed,
it is assumed that the user can select any of them, not that they must
accept all" — so the document is not silent and discarding it lost
something it states. They become an SPDX `OR` expression, which CycloneDX
already carries.

Only when every operand is a recognised identifier. One the reader cannot
name leaves the set unstated rather than narrowed to the rest, because
"MIT or something else" recorded as MIT is the confident wrong answer.

Correction to the previous commit: it claimed nothing ran this audit. That
was wrong. `audit-non-godot-parity.mjs` imports the collector and runs both
Horizon test files, and CI and the pre-commit hook both run that. The audit
was enforced all along, just indirectly, and I read the absence of the npm
script name from the workflows as absence of enforcement. The duplicate
wiring is reverted; a test now pins the real path instead.

The reader is the substantive change. It read the config out of masked
source text, and review kept finding shapes it got wrong: a ternary arm
taken for a value, a quoted key invisible because the masker blanks strings
with their quotes, an escaped key that JavaScript decodes to a different
name, a string whose escaped delimiter ended it early, a `let` rebound
before use, a parameter shadowing the binding it resolved.

None of that needed solving. The masker this file already imported is built
on the TypeScript compiler, so a real parser was a dependency the whole
time. It now walks the syntax tree: follow `android.horizon.appId` through
object literals and `const` bindings, resolve names by scope the way the
language does, and report anything else.

That also makes the spread rule exact rather than blanket — a spread before
the winning assignment loses to it and is fine; one after it can replace the
value and is reported. Ordinary configs that earlier readers refused, like a
comment holding a quote or an escaped delimiter in an unrelated string, are
read correctly now.

… does

Eight defects from review, all reproduced first.

Wrong value read. The plugin tuple was found anywhere in the module, so an
unused fixture stood in for the entry the build receives; it now has to be
reached through a `plugins` value, and two candidates are an ambiguity this
reports rather than picks from. Binding resolution only looked at
`VariableStatement`s, so a `for (const options of …)`, a catch binding and a
destructured name all fell through to an outer constant of the same name.
The parser recovers from a syntax error and hands back a tree anyway, so a
truncated config read as one that declares the id; `parseDiagnostics` is
checked now.

Correct configs refused. A spread made the object unreadable even when a
later explicit assignment wins over it — JavaScript guarantees the last one
does, so the check is positional now. `{horizon: {appId}}` bound to a
`const` string was reported as having no literal id, which is what this
audit claims to follow. A no-substitution template has a definite value and
is accepted; one with substitutions is not. `options!` changes the type,
not the value.

The wiring test asserted enforcement by substring, so `echo 'node
scripts/audit-non-godot-parity.mjs'` satisfied it, and it lived in the
suite the parity audit itself launches — removing that invocation would
have removed the test along with it. It now requires the command to BE the
audit, and lives in the ci-paths suite, which CI runs separately.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Six defects from review, all reproduced first.

The plugin tuple only had to appear under some `plugins` key, so one nested
inside another plugin's own options counted as a registration; it must be a
direct element now. A computed `["plugins"]` key was skipped entirely, which
let a stale object elsewhere supply the entry instead.

Enums and namespaces bind a name like anything else, and a `const` in an
earlier switch clause shares one scope with the clauses after it — missing
both let an outer constant stand in for a shadowed binding. In the other
direction, a loop header was counted as binding in the block that contains
it, so `for (const options of []) {}` shadowed a real `options` declared
beside it.

And `const` binds the name, not the contents. A config that writes to a
property after building the object is not described by the literal this
reads, and no scope analysis can see that — so a module that writes to
object properties, deletes one, or reaches for `Object.assign` is refused.
Our own configs do none of it.

Four shapes stay refused on purpose, now with a test that says so: a
`plugins` array returned by a helper, two branches registering the same
options, a getter, and an id reached through the prototype. Each needs the
module to run.

The wiring test also now requires the CI step to be unconditional, since
`if: false` left every assertion passing. It still cannot prove CI executes
the step, and says so.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Last round's mutation veto was the wrong shape. It refused any module that
wrote to any property, which rejects `config.name = "Example"` — ordinary
Expo — while still missing `(options.x.y) = ""`, `+=`, `++`, a for-of
target, a destructuring target and `Reflect.set`. Both directions came from
asking a question about the whole module instead of about the value being
read.

It now asks the narrow question: does anything write through one of the
bindings this walk actually followed to reach the id? That catches every
form above and leaves unrelated mutation alone. What it cannot see is a
config that hands the object to something that mutates it; that needs
escape analysis, and it says so.

The `plugins` array now has to be one the exported config can reach —
following properties, elements, spreads, `const` bindings, returned values
and call arguments — so a stale constant holding a complete entry no longer
answers for an export that registers nothing. Following call arguments is
deliberately generous: the real config returns `helper(expoConfig)`, and
this keeps the boundary the docs already state.

Also read correctly now, each of which was a false reject: `export default
function config() {}`, a spread of a `const` array of entries, and a
`const` holding the plugin path. And two more shadows: a named function
expression binds its own name inside itself, and a `var` belongs to its
function however deeply it is written.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Review found the write check wrong in both directions again, and the cause
was that it matched names. `const alias = options` then a write through
`alias` was missed; a helper with an unrelated parameter called `options`
made a valid config fail. It follows `const x = y` links now and compares
declarations, so an alias counts and a same-named parameter elsewhere does
not.

Three more writes it did not see: mutating the entries array itself
(`entries.pop()` removes the plugin), a rest target in a destructuring
assignment, and — in the other direction — it treated every argument of
`Object.assign` as written, so `Object.assign({}, options)`, which only
reads ours, failed. Only the target position counts, and only on `Object`
and `Reflect`.

The rest are the plugins array. A spread after `plugins` in the exported
config can replace it, exactly as one can deeper in the options; that is
reported rather than read past. `[...entries, ...entries]` registers twice,
which the cycle guard was collapsing into one. And three ordinary export
forms were unreadable: `export {config as default}`, and `module.exports =
config`, which Expo allows in a `.ts` config.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Review called all four findings plausible maintainer code, and three came
from the previous commit's fixes.

The plugins array was found by scanning every object in the module. So a
discarded `module.exports` branch, or a `base` whose spread is followed by
`plugins: []`, could answer for the exported config — and unrelated
`extra: {plugins: [], ...}` data could make a valid config unreadable. Only
the exported object's own `plugins` counts now, resolved through wrappers,
bindings, returned values and call arguments. A function may return more
than one object, since a guard clause returning `{}` is ordinary; more than
one of them carrying `plugins` is the ambiguity worth reporting.

Aliases were followed only through `const x = y`, so `const horizon =
options.android.horizon` disconnected, and a write through it went unseen.
Aliases now carry the property path they were reached by, including through
destructuring.

That path also makes the write check precise. `options.ios = {}` cannot
disturb `android.horizon.appId` and no longer fails a valid config, and
`entries.push("expo-router")` adds a plugin rather than removing ours —
only mutators that can remove or reorder count.

One thing this round removed rather than added: a computed key whose
expression is a string literal is just that name, at every level.

…rm TFMs

Two reviewers independently found the same defect: a destructured alias
rebuilt its path from the local name, so `const {android: target}` recorded
`target` and a write through it was missed. The path now comes from the
source property, including through nested patterns, and bracket access with
a string literal is a named property on both sides — so
`options["android"]["horizon"]` is followed, and `options["ios"] = {}` no
longer fails a valid config.

`entries.length = 0` empties the plugins array, but the array binding was
being given the path down to the app id, so the write looked irrelevant.
Bindings found while locating the entry carry no path: any write into them
can remove it.

Separately, and not from this branch: a NuGet target framework had to start
with an alphanumeric, so `.NETStandard2.0` — the long spelling, used by
microsoft.maui.controls, which this repository depends on — threw away the
whole nuspec. Four real nuspecs now parse that did not.

The XML reader also accepted four documents that are not well-formed: an
unquoted declaration version, two attributes with no space between them, a
comment ending in `-`, and a repeated DOCTYPE. Its tests moved into a file
of their own, which the install-free release job now runs.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Four findings from review, all reproduced.

A binding holding the exported config was resolved without being tracked,
so `config.plugins.length = 0` emptied the very array being read and the
audit still passed. It carries the path down to `plugins` now, which also
keeps `config.name = "x"` from failing a valid config.

Rest bindings had the wrong semantics in both directions. `const {...copy}
= options` copies the properties, so `copy.android` IS `options.android` —
recording a `copy` step lost the alias. `const [...copy] = entries` builds
a new array, so emptying it changes nothing, and rejecting that was wrong.

An array index is a slot, not an unknown. Writing to `entries[1]` changes
another plugin while ours sits at 0, and that no longer fails the config.

Not from this branch: a `<group>` with no targetFramework is NuGet's
fallback group, documented in its reference and used in its own example.
Requiring the attribute threw away every nuspec that has one.

Verified against real registry documents: 5 nuspecs and 3 POMs parse,
including microsoft.maui.controls.

`descent` and `entrySlot` live at module scope and the audit inspects six
sources in a loop, so the same two configs are checked in both orders.

Three findings from review, two of them holes the previous commit opened.

The entry's slot was consulted for every tracked array, not just the plugins
list. So `const plugin = [path, options]; plugin[1] = {}` was mistaken for a
write to another plugin's slot and passed. Only the bindings that hold the
plugins array carry a slot now.

An object rest does not carry what its siblings took: in `const {android,
...rest}`, `rest.android` is a new property of a new object, and writing it
leaves the original alone. The rest binding records the names its siblings
claimed, so that write is no longer read as a write to the app id — while
`const {ios, ...rest}` still is, because `rest.android` is the same object.

Not from this branch: merging a dependency that appears in both a
framework group and the fallback group kept whichever scope came first, so
the answer depended on the order the document listed them in. Optional now
requires every group carrying it to be framework-scoped.

Rounds 18 to 21 of review each found a defect in the same machinery, and
each round's fix introduced the next round's: the whole-module veto was
wrong in both directions, then name-vs-declaration matching was, then the
config binding went untracked and rest semantics were wrong both ways, then
the slot rule leaked and rest exclusions were unmodelled.

Reviewing the pattern rather than the next defect: that machinery tried to
decide which property a write could reach, and being right about that means
modelling a JavaScript heap. Three shapes proved it — an excluded property
put back to re-alias the original, an `unshift` that makes a remembered
slot stale, and two properties holding the same object. All passed while
the app id was empty at runtime.

So the rule is blunt now. Any direct mutation through a binding this walk
followed — the exported config, the plugins array, the tuple, the options
object, or an alias of one — refuses the config, whatever it touches. That
is a policy about the source, not an evaluation of it.

It costs false rejects: `options.ios = {}` cannot reach the app id and is
refused anyway. That is the trade, taken deliberately — a refusal is
visible and the fix is to build the property in the literal, which is how
this repository's own config is already written. A hole is silent.

140 lines smaller. What it still cannot see is a write made by a function
the object is passed to, and security/README.md says so.

Two gaps the confirmation pass found, both older than the simplification.

Mutator calls were only recognised through a dot, so `entries["pop"]()`
emptied the plugins array unseen.

And a shallow copy keeps the very same members. `const [...copy] = entries`
builds a new array, but `copy[0]` IS `entries[0]`, so `copy[0][1] = {}`
replaced our options; `const copy = {...options}` has the same property.
Calling an array rest "aliases nothing" was wrong, and the documentation
repeated it.

Following spreads makes the rule simpler rather than more elaborate: every
destructured name aliases now, and the special case for array rest is gone.
The cost is one more refusal in the same family as the others — emptying a
copy of the array is reported although the original is untouched — and it
is in the tests beside them.

What the boundary now claims is only what it does: a write made by a
function the object is passed to is still not seen.

`const copy = {android: options.android}` holds the very object the audit
read, so `copy.android.horizon.appId = ""` cleared the real id and the
config still passed. Following spreads but not ordinary members was an
arbitrary line: both hold the same object.

The chain follows every identifier a literal refers to now, skipping its own
property names, which are keys rather than values. `const copy =
[entries[0]]` closes with it.

security/README.md said alias mutations are refused without naming this
case, and a test comment still repeated the retracted claim that an array
rest aliases nothing. Both corrected.

It claimed "anything built from the tracked value"; it follows object and
array literals. An alias a call produced — `Object.assign({}, options)`
returns one — is not followed, and now sits beside the escape-analysis gap
rather than being covered by a phrase that overstated the check.

Two from the second reviewer. `<!doctype a>` was accepted although XML
spells it in upper case, and a `>` inside a quoted system identifier ended
the declaration early, so a well-formed document was refused.

Neither appears in a published POM or nuspec, but both are the class this
reader exists to close: one accepts markup that is not well-formed, the
other rejects markup that is.
