- Around line 13-15: Update the README’s later embed_files example and
integration text to use .fetch as the pointer format, consistently with the
introduction. Refer to .lnk only when documenting legacy build-time

format.

All three review findings addressed in 9911287.
Worth separating two cases, because they have different histories:
I did not take the suggested staging-path/relative-identity redesign. If you would still prefer collision-free staging paths, that is a reasonable follow-up, but it should be its own change with the Cache error wording (Minor) — fixed. That branch takes both spellings now; the message said README (Minor) — fixed, details in the inline reply. |

I found one new minor issue. Line 41 in
|
`.lnk` served two roles with different consumers, formats and guarantees:
FastLED's runtime asset link (plain text, read on the MCU by
`fl::parse_lnk`, sha256 optional) and fbuild's build-time blob pointer
(JSON, read on the build host, sha256 mandatory because the resolver caches
by content). Sharing one extension read as one concept, so people normalized
toward whichever form they met first — converting a runtime link to fbuild's
JSON schema looked like tidying, and `fl::parse_lnk` then took `{` as the
URL (FastLED/FastLED#4012). A test caught that one; a sketch author gets a
silently wrong URL.
Per #1369 the roles get distinct extensions rather than
converged formats — converging on JSON means carrying a JSON parser on the
MCU for no user-visible benefit, and converging on text means giving up the
mandatory digest the content-addressed cache depends on.
`.lnk` keeps the runtime role. Build-time pointers are `.fetch`: it names
what the build does with the file, and `foo.bin.fetch` cannot be misread as
being the blob the way `foo.bin.blob` can.
Three places stripped `".lnk"` by hand and would each have refused a
`.fetch` *after* recognizing it — `strip_pointer_extension` is now the one
definition, next to `is_blob_pointer` (which replaces `has_lnk_extension`,
whose name would no longer be true). The e2e suite proves both halves: the
main pipeline run uses `.fetch`, and the sha-mismatch run deliberately keeps
`.lnk` so back-compat is demonstrated rather than asserted in a comment.
The scanner's malformed-file warning now distinguishes the two. A `.lnk`
that will not parse as JSON is far more likely a runtime asset link — not
fbuild's to resolve — than a corrupt pointer, so calling it "malformed" was
telling the user their correct file was broken. `.fetch` is unambiguously
ours and keeps the blunt wording.
Out of scope, per the issue's own open questions: the `fbuild lnk`
subcommand name, a deprecation window for `.lnk` reads, and whether
`assets.json` folds into this form.

Review follow-ups on #1369. A materialized target is named after the pointer's blob, so two pointers whose blob names match land on one path: the second overwrites the first and both embed entries end up holding the second blob's bytes. Firmware then carries the wrong asset with nothing to indicate it. That is pre-existing for two `.lnk` in different directories, but `.fetch` adds the case where `logo.bin.fetch` and `logo.bin.lnk` sit in the *same* directory — which is exactly what a half-finished migration looks like, and `fbuild lnk add` will happily produce it next to an existing `.lnk`. The resolver now refuses, naming both entries and the path they collide on. Confirmed by a test that fails on the previous code, where the collision resolves silently. Also: the "disk cache unavailable" error said `.lnk entries` on a branch that now takes both spellings, and the README's later `embed_files` example and integration notes still presented `.lnk` as the current format while the introduction called it legacy.

Use filesystem-aware keys for materialized targets.
materialize_lnk_entry strips the pointer extension and preserves the blob name. On Windows and default macOS filesystems, Logo.bin.fetch and logo.bin.lnk therefore target the same file. claimed uses lexical PathBuf equality, so the second materialization can replace the first and both entries can reach objcopy.
Use fbuild_core::fs::comparison_key for claimed, and add a Windows test for case-colliding blob names.

The issue leaves one thing open: what to call it. This picks
.fetch,from the three candidates it offered.
.blobdescribes the payload, not the pointer —track.mp3.blobreads asthough the file is the blob, which is the opposite of what it is.
.remoteis an adjective;track.mp3.remotedoes not say what the file does..fetchnames what the build does with it, andtrack.mp3.fetchreads as"fetch instructions for track.mp3". It also matches the existing
fbuild-packages-fetchvocabulary.Easy to change before anything ships — the write side is one
format!.What changed
.lnkkeeps the runtime asset-link role.fbuild lnk addnow writes.fetch,and both extensions are read, so pointers written before this keep working.
Three places stripped
".lnk"by hand:embed::materialize_lnk_entrymaterialize::strip_lnk_suffixhas_lnk_extensionas the recognizer)Each would have recognized a
.fetchand then refused it — the scanner findsit, materialize hard-errors with "does not end in .lnk".
strip_pointer_extensionis now the single definition, alongside
is_blob_pointer(which replaceshas_lnk_extension, whose name would otherwise be a lie).The warning that was telling users their correct file was broken
The scanner logged
skipping malformed .lnk filefor anything that failed JSONparse. But a
.lnkthat will not parse as JSON is far more likely FastLED'sruntime asset link — plain text, read on-device, not fbuild's to resolve —
than a corrupt blob pointer. It now says so.
.fetchis unambiguously ours andkeeps the blunt wording.
Verification
RED first:
is_blob_pointer/strip_pointer_extensiontests failed to compile,then passed. Switching the e2e fixture to
.fetchsurfaced the third strip site(
materialize::strip_lnk_suffix) as a real failure rather than by inspection.soldr cargo test -p fbuild-toolchain --lib lnk::— 47 passed, 0 failedsoldr cargo test -p fbuild-packages --test lnk_e2e— 4 passed, 0 failed-D warnings— cleanlnk_e2ecovers both spellings on purpose: the main pipeline run uses.fetch,and
lnk_pipeline_rejects_sha_mismatchdeliberately keeps.lnkso back-compatis demonstrated by a passing run rather than claimed in a comment.
Out of scope
Per the issue's own open questions:
fbuild lnksubcommand name is unchanged (the issue keeps it),and no deprecation warning is emitted for
.lnkreads; the window is stillopen.
assets.jsonfolds into this form is untouched.Internal vocabulary (
LnkFile,DiscoveredLnk, thelnkmodule) is alsounchanged. The issue prices this at "one rename"; renaming the type surface
would be scope bloat.
Nothing in FastLED needs to change: its runtime
.lnkfiles keep theirextension and their parser, which is the point of the split.
