Summary

Thirty-one Go modules linked into the released binaries were missing from THIRD_PARTY_NOTICES.md. They are redistributed, so their licenses have to be disclosed there. Module count goes 207 → 238.

Adds a completeness gate so it cannot recur silently.

Motivation / Context

Found while investigating an unrelated make notices failure. It turned out main was the broken state, not the failure — the notices file has been incomplete, quietly, with nothing reporting it.

Cause 1 — a prefix collision in the ignore list. stdlib_ignore was built as:

go list std | cut -d'/' -f1

Keeping only the first path segment yields the bare token go, from go/ast, go/build, and friends. go-licenses --ignore matches by prefix, so go also matched every third-party module under go.opentelemetry.io and go.yaml.in. They were dropped with no error. Passing full stdlib package paths cannot collide that way.

Cause 2 — three modules go-licenses cannot classify. in-toto/attestation, in-toto-golang, and json-canonicalization ship a LICENSE the classifier does not recognise. All three are Apache-2.0; the committed copies are byte-identical to the vendored originals, independently verified in review.

Recovered:

Module group Mentions before After
go.opentelemetry.io 3 21
go.yaml.in 0 6
in-toto 0 7
json-canonicalization 0 3

Fixes: N/A
Related: #2374 (removing vendor/ is what surfaced this; that PR is blocked on it)

Type of Change

  • Bug fix (non-breaking change that fixes an issue)
  • New feature (non-breaking change that adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update
  • Refactoring (no functional changes)
  • Build/CI/tooling

Component(s) Affected

  • Other: tools/generate-notices, THIRD_PARTY_NOTICES.md, licenses/overrides/

Implementation Notes

Committed license copies rather than reading from the module cache. Generation does not depend on how dependencies are materialised, and the exact bytes being disclosed are reviewable in-tree.

An earlier revision of this PR justified the copies by claiming in-toto/attestation's license was absent from its module zip. That was wrong — it is present, which is the only way go mod vendor could have produced vendor/github.com/in-toto/attestation/LICENSE. The override key was also github.com/in-toto/attestation/go/v1, a package path rather than the module path. Both corrected in 522a175.

The completeness gate is the durable part. Every third-party package reachable from ./cmd/... must be covered by an index entry or the build fails naming the packages. Nothing verified that before: the pipeline trusted go-licenses to report on what it was asked about, and it did not.

The gate skips index keys with no slash. go-licenses emits a bare github.com row when it cannot resolve a package to a module. Kept as a prefix, that single row matches every package under that host — which made the first version of this check vacuous and is why the negative test below matters.

The overrides are not an escape hatch. The gate fails on any uncovered package whether or not it is listed, so the only way to satisfy it is to disclose a license, naming the file and the SPDX id.

Testing

make notices   # rc=0, "Wrote THIRD_PARTY_NOTICES.md (238 Go modules, 130 Python packages)"
make lint      # rc=0

Verified in both directions rather than only the happy path:

  • Positive: full configuration passes and the notices file lists all four module groups at the counts above.
  • Negative: removing LICENSE_OVERRIDES fails the build with rc=2, naming exactly the packages left undisclosed:
ERROR: package(s) linked into the released binaries have no license entry:
  github.com/cyberphone/json-canonicalization/go/src/webpki.org/jsoncanonicalizer
  github.com/in-toto/attestation/go/v1
  github.com/in-toto/in-toto-golang/in_toto
  ...

The first version of the gate passed that negative test incorrectly — the bare-github.qkg1.top key masked it. Worth running the negative case if this is ever modified.

Risk Assessment

  • Low — Isolated change, well-tested, easy to revert
  • Medium — Touches multiple components or has broader impact
  • High — Breaking change, affects critical paths, or complex rollout

Rollout notes: THIRD_PARTY_NOTICES.md grows by ~3,900 lines, which is the disclosure that was missing. make notices-check in the merge gate will now hold the file to the corrected content. No runtime or build behavior changes.

Checklist

  • Tests pass locally (make test with -race) — unaffected; make notices and make lint verified
  • Linter passes (make lint)
  • I did not skip/disable tests to make CI green
  • I added/updated tests for new functionality — the completeness gate, verified in both directions
  • I updated docs if user-facing behavior changed
  • Changes follow existing patterns in the codebase
  • Commits are cryptographically signed (git commit -S)

Thirty-one Go modules linked into the released binaries were absent from
the notices file. They are redistributed, so their licenses have to appear
there. Module count goes 207 -> 238.

Two independent causes.

The stdlib ignore list was built with `go list std | cut -d/ -f1`, keeping
only the first path segment. That yields the bare segment `go` (from
go/ast, go/build, ...), and `go-licenses --ignore` matches by PREFIX — so
`go` also matched every third-party module under go.opentelemetry.io and
go.yaml.in, dropping them silently with no error anywhere. Passing full
stdlib package paths cannot collide that way.

Separately, go-licenses cannot classify three modules: in-toto/attestation
is a nested module (path ends /go/v1) whose LICENSE lives at the repository
root and is therefore absent from its module zip, and in-toto-golang and
json-canonicalization ship a LICENSE its classifier does not recognise. All
three are Apache-2.0, verified by reading the files. Committed copies under
licenses/overrides/ resolve them, keeping generation hermetic.

Recovered: opentelemetry 3 -> 21 mentions, go.yaml.in 0 -> 6, in-toto
0 -> 7, json-canonicalization 0 -> 3.

Adds a completeness gate so this cannot recur silently: every third-party
package reachable from ./cmd/... must be covered by an index entry, or the
build fails naming the packages. Nothing verified that before — the whole
pipeline trusted go-licenses to report what it was asked about, and it did
not.

The gate skips index keys with no slash. go-licenses emits a bare
"github.com" row when it cannot resolve a package to a module, and kept as
a prefix that single row matches every package under that host, which made
the first version of this check vacuous.

Verified both directions: the full configuration passes and lists all four
module groups, and removing the overrides fails the build naming the exact
packages left undisclosed.

📝 Walkthrough

Walkthrough

The change adds Apache-2.0 license overrides for three dependencies. tools/generate-notices tracks linked packages across release platforms, applies overrides, filters standard-library packages by full path, validates override linkage, and checks that all linked third-party packages appear in the license index.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 3d09f

The PR expands third-party license disclosures and adds a completeness gate, but the override license files are still flagged as omitting the complete Apache-2.0 terms. This could leave released notices incomplete and warrants correction or explicit owner acceptance before merge.

Declining this one, with evidence.

These files are byte-identical to what upstream ships — verified independently by @lockwobr, who diffed all three against the vendored originals. They are the short Apache-2.0 notice because that is the LICENSE those three projects publish, not because anything was truncated here.

Two reasons to keep them verbatim:

The full text is already in the document. THIRD_PARTY_NOTICES.md contains 164 complete Apache-2.0 bodies from other dependencies, so a recipient does receive the license terms.

It matches the existing pattern. 30 entries already present use the same short upstream notice. Substituting canonical text for these three would make them the only entries in the file that do not reproduce what upstream actually distributes — which is worse for a document whose purpose is accurate attribution.

If the project decides the notices file should carry the full text wherever a dependency ships only the notice, that is a reasonable policy — but it applies to all 30 existing entries, not to the three this PR adds, and belongs in its own change.

The core diagnosis is right: go list std | cut -d/ -f1 yields the bare token go, and --ignore prefix-matching then swallowed every go.opentelemetry.io / go.yaml.in module. Passing full stdlib paths is the correct fix, and the completeness gate is the durable part. Catching that the bare github.com key made v1 of that gate vacuous is exactly the kind of thing that normally ships unnoticed.

Four things below, ordered by impact, plus two nits. Nothing blocking the approach.

Six findings from review of #2384, all correct.

The three index URLs were 404s. `ov_file` already carries the full module
path, so prefixing `https://${ov_module}/blob/HEAD/` doubled it. They were
also the only rows using an upstream URL scheme while the other 32 rows
point into this repository. Now points at the committed copy, which matches
the existing scheme and is honest about where the text came from.

`github.com/in-toto/attestation/go/v1` is a package, not a module —
vendor/modules.txt records the module as github.com/in-toto/attestation
v1.2.0. The index was advertising a module path that does not exist.

The rationale for committing that copy was also wrong: the LICENSE *is* in
the module zip, which is the only way `go mod vendor` could have produced
vendor/github.com/in-toto/attestation/LICENSE. Corrected to the reason that
actually holds — generation should not depend on how dependencies are
materialised, and the disclosed bytes should be reviewable in-tree.

Dropping `export GOFLAGS=-mod=vendor` did not switch to module mode: Go
selects vendor mode on its own when vendor/ is present, so the removal
changed nothing and the comment claiming otherwise was false. The recovery
came from the ignore-list fix. Restored explicitly so the collection mode is
a decision rather than a side effect of the tree layout; removing vendor/
would otherwise flip it silently and rewrite every URL in the file.

The completeness gate ran on the host platform only while the collection it
guards loops over four. Build-tagged sources import different transitive
dependencies per GOOS/GOARCH — the reason the union loop exists at all — so
a linux-only dependency was invisible on a macOS run. `go list -deps` now
runs inside the platform loop and the results are unioned.

Two nits, both real: the staleness check interpolated a module path into a
regex where `.` matches any character, now literal; and the gate's two temp
files were not registered with the EXIT trap, so any early exit leaked them.

Declined one suggestion: replacing the committed license files with the full
Apache-2.0 text. They are byte-identical to what upstream ships, the
document already carries 164 full Apache-2.0 bodies, and 30 existing entries
use the same short upstream notice. Substituting canonical text would
misrepresent upstream and diverge from every other entry.

Verified both directions again: full configuration passes at 238 modules
with all four module groups present and the three URLs no longer doubled;
removing the overrides fails naming the undisclosed packages.

All six review findings addressed in 522a175b, each answered on its thread. Summary:

Finding Fix
Three index URLs 404 (path doubled) Point at the committed copy, matching the scheme the other 32 rows use
attestation/go/v1 is a package, not a module Key is now github.com/in-toto/attestation per vendor/modules.txt
Rationale for committing the copy was false Corrected in the comment and the PR body — the LICENSE is in the zip
Dropping the export did not switch modes -mod=vendor restored explicitly; the mode flip belongs in #2374
Gate was single-platform, collection is four go list -deps moved inside the PLATFORMS loop and unioned
Regex interpolation, untrapped temp files Literal grep -F; both files registered with the existing EXIT trap

Re-verified in both directions after the changes: full configuration passes at 238 modules with all four module groups present and no doubled URLs; removing LICENSE_OVERRIDES fails naming the undisclosed packages. make lint green.

One suggestion declined, with reasoning on its thread: replacing the committed license files with canonical full Apache-2.0 text. They are byte-identical to what upstream ships (you verified this independently), the document already carries 164 full Apache-2.0 bodies, and 30 existing entries use the same short upstream notice. Substituting would make these three the only entries that do not reproduce what upstream distributes. If the project wants full text wherever a dependency ships only the notice, that is a defensible policy — it just applies to all 30, not these three.

Two things your review caught that I want to name, because they were the same mistake twice: I asserted a mode change and a missing license file without verifying either, in a PR whose entire argument is that unverified assumptions had hidden 31 dependencies. The go list -m failure I used to derive /go/v1 was itself a vendor-mode artifact I had already run into earlier in the same file.

Multi-persona review (Correctness · Supply-chain/Licensing · Operability-CI-DX), each finding independently confirmed against the resolved code by a senior meta-reviewer. Re-run against head 522a175b after your fix(licenses): address review commit. Line links/anchors pinned to that head.

⚠️ @lockwobr has a standing CHANGES_REQUESTED review — the fix commit resolves the substance behind it; worth a re-request.

Overall — Comment (no blocker; both remaining items are Minor)

The diagnosis and the durable part (a completeness gate that fails the build when a linked package has no license entry, and the catch that a bare github.com index key made v1 of that gate vacuous) are solid. The follow-up commit resolves every Major and both nitpicks from the first pass, and the committed THIRD_PARTY_NOTICES.md is now correct — all rows point at github.com/NVIDIA/aicr/blob/HEAD/… and the in-toto/attestation row uses the real module path. Two 🟡 Minor items remain, both hardening the gate against the same silent-omission class it exists to catch; safe to merge with or without them.

Prior-feedback status

Disposition Finding Where
✔️ Addressed 🟠 3 override Source URLs were path-doubled → 404 script L377 + committed doc now use NVIDIA/aicr/blob/HEAD/licenses/overrides/…; zero non-NVIDIA URLs remain
✔️ Addressed 🟠 Index advertised non-existent module …/attestation/go/v1; comment/PR-body falsifiable override key now github.com/in-toto/attestation; the "not in the module zip at all" claim removed
✔️ Addressed 🟠 Vendor-mode coupling + misleading "module mode surfaces them" comment false comment replaced; export GOFLAGS="-mod=vendor" re-added, so script and merge-gate.yaml:628 agree. Residual: when #2374 removes vendor/, both sites now hard-fail (inconsistent vendoring) — loud, not silent — but must be updated together in that PR
✔️ Addressed 🟠 Completeness gate ran single-platform; collection is four-platform go list -deps ./cmd/... moved inside the PLATFORMS loop with GOOS/GOARCH, unioned into LINKED_RAW
✔️ Addressed 🔵 . in ${ov_module} grep regex now grep -qxF + grep -qF
✔️ Addressed 🔵 INDEX_KEYS/LINKED_LIST temp files not trapped added to the EXIT trap; success-only rm -f removed
✖️ Open 🟡 Gate prefix-cover can't distinguish a nested submodule with its own/absent license from its parent see inline L421
✖️ Open 🟡 Gate fails open on a partial go list / awk failure see inline L333

✅ Confirmed non-issue

CodeRabbit's "replace the 3 override LICENSEs with the full Apache-2.0 text" (flagged Major) — refuted. The 3 committed copies are byte-identical to what those upstreams actually ship; replacing them would make the disclosure diverge from the dependency's real LICENSE. The full Apache-2.0 terms already appear 164× elsewhere in the same file, so §4 ("recipients receive a copy of the License") is satisfied within the artifact. At most a nitpick.

Summary

Tier Count Items
🔴 Blocker 0
🟠 Major 0 (4 resolved)
🟡 Minor 2 prefix-cover blind to nested submodules · gate fails open on go-list/awk error
🔵 Nitpick 0 (2 resolved)

Recommendation: mergeable as-is. The two 🟡 items are worth folding in since they harden the gate against exactly the failure mode this PR targets, but neither blocks.

The completeness gate credited a package to any index entry that was a path
prefix of it. Nested submodules are separate modules with their own licenses,
so an ancestor entry vouched for a descendant whose license was never seen -
the exact silent-omission class the gate exists to catch. This graph already
contains such submodules (oauth2adapt under cloud.google.com/go/auth, ~20
aws-sdk-go-v2/*), so the hole was live, not latent.

Compare module identity on both sides instead. Linked packages resolve to
their owning module via go list -deps -f '{{.Module.Path}}'; index keys resolve
to the longest known module containing them, since go-licenses keys a row on
the directory a license covers (k8s.io/apimachinery/pkg), not an import path.
A key inside a nested submodule now credits that submodule and never its
parent.

Also surface go list stderr rather than discarding it: on a partial failure
set -e aborts, but with stderr hidden the abort carried no explanation.

Round 2 — njhensley review, both findings addressed in 3d09f8f

# Finding Verdict Action
1 Prefix-cover cannot distinguish a nested submodule from its parent Confirmed, and live rather than latent Gate now compares module identity
2 Gate fails open on partial go list / awk failure Premise falsified; real defect one step over stderr surfaced, awk status checked

1 — the hole was already open

The graph contains nested submodules today: cloud.google.com/go/auth/oauth2adapt under cloud.google.com/go/auth, ~20 aws-sdk-go-v2/* under aws-sdk-go-v2. Proved the old gate blind before touching it — parent indexed, submodule absent, submodule package linked → PASSES.

Both sides now compare on module identity. Linked packages resolve via go list -deps -f {{.Module.Path}}. Index keys resolve to the longest known module containing them, because go-licenses keys a row on the directory a license coversk8s.io/apimachinery/pkg, github.com/sigstore/protobuf-specs/gen/pb-go — which is neither a module nor an import path. Requiring exact module paths rejected 33 legitimate entries; longest-module resolution keeps the fix, since a key under .../service/kms lands on kms and never on the parent.

2 — worth being precise about

The script runs set -euo pipefail, is straight-line, and the gate is top level. Tested rather than assumed: set -euo pipefail; x=$(false) does abort (rc=1). Both spots were already fail-closed.

The real defect is the consequence: 2>/dev/null meant a go list failure aborted with no explanation — errexit kills it silently. Both calls now capture and print stderr; the awk runs behind an explicit status check.

Verification

  • Positive: make notices rc=0, 238 modules, THIRD_PARTY_NOTICES.md byte-identical. make notices-check rc=0. make lint rc=0. shellcheck clean.
  • Negative (new): dropping index keys under .../service/kms while leaving the parent → fails naming github.com/aws/aws-sdk-go-v2/service/kms. This is the case that passed before.
  • Negative (existing): emptying LICENSE_OVERRIDES → fails naming the three override modules.

Re-verified after your merge of main; regenerates identically.

Not done, deliberately

No permanent regression test. The awk is inline, so locking it down means extracting it to its own file or running real go-licenses (~90s) inside make lint. Both are structural calls I would rather leave to you than bundle into a review round — happy to do either as a follow-up.

Also left open: the CodeRabbit thread asking for full Apache-2.0 text in the three committed license copies. Those are byte-identical to what upstream ships, and 30 existing entries in this document use the same short notice, so substituting would make these three the only ones not reproducing their upstream file. That is a judgement call for a human, not one for me to resolve.

  • 🟠 Index advertised non-existent module …/attestation/go/v1 + falsifiable comment → keyed on the real module github.com/in-toto/attestation; comment corrected.
  • 🟠 Vendor-mode coupling / misleading "module mode surfaces them" comment → -mod=vendor made explicit and single-sourced with merge-gate.yaml:628; false comment removed.
  • 🟠 Completeness gate ran single-platform → go list -deps moved inside the PLATFORMS loop and unioned.
  • 🟡 Gate prefix-cover blind to nested submodules → reworked to match on module identity, resolving each index key to its owning module and walking up to the longest known module so a nested submodule (oauth2adapt, aws-sdk-go-v2/*) never inherits its parent's entry.
  • 🟡 Gate failed open on partial go list/awk failure → both now fail closed with explicit status checks and surfaced stderr.
  • 🔵 grep regex . and untrapped temp files → both fixed.

The in-toto/json-canonicalization override copies are byte-identical to what those upstreams ship (CodeRabbit's "replace with full Apache-2.0 text" was correctly not taken — the full terms already appear elsewhere in the file). The gate rewrite is output-neutral and notices-freshness is green at this head.

The completeness gate — failing the build when a released-binary dependency has no license entry, now on module identity across all four release platforms — is a genuinely durable improvement over trusting go-licenses to self-report. Nice work.

Note: @lockwobr's earlier CHANGES_REQUESTED is still on record; its substance is fully addressed, so this may need their re-review to clear the branch protection.

All six points from my earlier review are fixed at 3d09f8f. I verified each independently rather than from the replies, and clearing my CHANGES_REQUESTED.

On the mode fix specifically: restoring the explicit export GOFLAGS="-mod=vendor" does more than document intent, it matches how the artifacts are actually built. .goreleaser.yaml sets GOFLAGS=-mod=vendor in each build's env, so notices are now collected under the same module mode that produces the binaries. That is a stronger justification than "redundant but explicit".

The unprompted change is the best part of this PR. Switching coverage from path prefixes to module identity closes a class that was not in my review. I tested the claim rather than reading it: deleting the single index row for cloud.google.com/go/auth/oauth2adapt, a genuinely nested submodule,

NEW gate (module identity):  cloud.google.com/go/auth/oauth2adapt   <- caught
OLD gate (prefix match):     (silent)                               <- parent vouched for it

So the previous gate would have passed an undisclosed submodule whose license may differ from its parent's, which is the original bug one level down.

End-to-end check using the release binary's build info, independent of any of this script's machinery:

$ go version -m dist/aicr_darwin_arm64_v8.0/aicr | awk '$1=="dep"{print $2}'   # 188 modules
uncovered against the new notices index: 0

The same check reports 27 uncovered against main, which is an independent confirmation of the disclosure gap this PR closes.

Gate scope also checks out: goreleaser builds cmd/aicr and cmd/aicrd and ko builds ./cmd/aicr, so ./cmd/... covers everything released, plus cmd/gate as a harmless superset. And notices-freshness genuinely ran (1m1s, pass), so the committed file was regenerated by the new script in a clean environment rather than only locally.

Two non-blocking notes inline. Neither needs to hold the merge.

Comment thread tools/generate-notices
# paths. A license is a property of the module, and nested submodules are
# independent modules that may carry a different license than their parent
# — this dependency graph already contains several (oauth2adapt under
# cloud.google.com/go/auth, ~20 aws-sdk-go-v2/* under aws-sdk-go-v2).

Non-blocking, but the count is off and the comment undersells itself.

There are 13 aws-sdk-go-v2/* submodules in the graph (14 counting the root), not ~20:

$ grep -c '^# github.com/aws/aws-sdk-go-v2/' vendor/modules.txt
13

More usefully, the class is much wider than the two examples. Counting every module whose path sits under another module in this graph:

$ # modules nested under another module
36

So the prefix-matching hole this replaces was live across 36 modules, not just oauth2adapt plus the aws family. Given how much this file leans on its comments being exact, I would either correct the number or drop it: "several dozen nested submodules, including aws-sdk-go-v2/* and oauth2adapt" is both accurate and stronger.

Same number appears twice, here and at line 450.

Informational only, no change requested.

This is now the expensive part of the script: go list -deps ./... measures ~7.1s on my machine, and it runs once per platform alongside the ./cmd/... list. The merge-gate job absorbed it fine (notices-freshness, 1m1s), so this is not a problem today.

If it ever becomes one, the package-to-module map is already sitting in vendor/modules.txt (module headers followed by their package lines) and can be parsed for free, no go list needed. Filing here only so the option is discoverable the next time someone profiles make notices.

Drops the 93 -mod=vendor pins and 14 vendor/modules.txt cache keys the deleted
tree backed, and points release builds at Artifactory in enforced mode.

Closes the gap between intent and reality: .goreleaser.yaml pinned
GOFLAGS=-mod=vendor and set gomod.proxy=false, so a release build contacted no
proxy at all. "Release dependencies flow through Artifactory" was aspirational.

Vendored source was never hashed against go.sum at build time -- appending a
line to a vendored file and building exits 0. Module-cache resolution verifies
every module against go.sum and sum.golang.org on every build.

Ordering constraints that are load-bearing, and why:

- The proxy is configured before the FIRST go command touching application
  deps (the go run in generate-slsa-predicate, not the goreleaser build).
  Later, and that command warms the cache from the public proxy, the release
  build fetches nothing, and a green run proves nothing about coverage.
- go mod download runs immediately after minting. The OIDC token lasts ~15
  minutes against a 30-minute job; pulling the graph up front means every later
  go command uses a warm cache and needs no credential. The one late consumer
  (go install go-licenses) gets a fresh mint -- GitHub's OIDC request
  credential is valid for the life of the job.
- cmd/gate/Dockerfile no longer compiles. A BuildKit stage cannot reach the
  proxy (GITHUB_ENV and $RUNNER_TEMP do not cross into it, and the credential
  is a bearer token so --build-arg is not an option), so a builder stage would
  resolve publicly while looking healthy. The binary is built on the runner
  instead, which also removes network egress from the image build.

Dependabot and fork PRs cannot mint the OIDC credential, so they get a new
credential-free gate: every module version added to go.sum must resolve on the
public proxy and be present in the public checksum database. Not equivalent to
asking Artifactory -- a deliberately withheld module still slips through -- but
it catches nonexistent versions and go.sum/transparency-log disagreement. The
strong check is the enforced release build, which fails by name.

Three defects found while doing this, all fixed and verified:

- make license-check had the same prefix-collision bug #2384 fixed in
  generate-notices: `go list std | cut -d'/' -f1` yields a bare `go` token, and
  --ignore matches by prefix, so 32 packages under go.opentelemetry.io,
  go.yaml.in and go.uber.org were silently exempt from the license policy gate.
- The GOFLAGS="-mod=vendor" prefixes also masked ambient GOFLAGS. Removing them
  let GOFLAGS=-trimpath through, which breaks runtime.Caller-based repo-root
  resolution in tests/notices and tests/releasepolicy. Restored as
  -mod=readonly at all 17 sites.
- go-licenses copies from the read-only module cache (0444/0555), so the
  multi-platform license merge failed with cp: Permission denied. vendor/ was
  writable; the module cache is not.

.licenses-cache/ now holds full upstream trees (go mod vendor pruned non-Go
files; the module cache does not), so it is excluded from yamllint and grype.
Without the grype exclusion the scan reported x/crypto v0.17.0 and v0.45.0 from
upstream go.mod files while this repo builds v0.55.0.

THIRD_PARTY_NOTICES.md regenerates to the same 238 modules, with each row now
linking to a version-pinned upstream license instead of a blob/HEAD/vendor/
path that would 404.

Decision and rationale recorded in ADR-023.
