Code review

Bugs: None found. The new parquet case in visualizeAsset (maplibre-stac.ts) correctly narrows appRef before use, follows the exact same delegation pattern (addVectorLayerFromUrl) already used by maplibre-source-coop.ts and maplibre-huggingface.ts, and the switch's exhaustiveness check (const unhandled: never = format) still holds since StacAssetFormat now includes "parquet". The type simplification (assetFormat no longer special-cases null for parquet) correctly makes GeoParquet both displayable and addable. Confidence: high.

Security: None found. No new user input handling, injection surface, or secret exposure. Confidence: high.

Performance: None found. No new loops, fetches, or blocking operations beyond the existing DuckDB-WASM vector loading path shared by other formats.

Quality:

• Minor/optional: assetFormat and assetDisplayFormat (stac-api.ts:584-586) are now identical pass-through functions since StacAssetDisplayFormat was collapsed into StacAssetFormat. Not a defect — likely kept for semantic clarity or future extension — but flagged as a possible simplification. Confidence: low (posted inline).
• Test coverage for the new parquet case is limited to the pure assetFormat/isVisualizableAsset helpers in stac-api.ts; the actual routing through visualizeAsset → addVectorLayerFromUrl in maplibre-stac.ts isn't independently unit-tested. This mirrors the existing gap for the geojson branch, so it's not a regression introduced by this PR. Confidence: low.

CLAUDE.md: All 19 shipped locale catalogs were updated consistently with en.json as source of truth, matching the i18n convention. No other guideline in CLAUDE.md applies to this change (no WASM/version-mirror constants touched). Confidence: high.

Overall this is a small, well-scoped, low-risk change that follows established conventions in the codebase closely.

📝 Walkthrough

Walkthrough

GeoParquet is now recognized as a STAC asset format. Azure object-store URLs can be resolved and signed when required. The MapLibre STAC plugin loads GeoParquet as vector layers. Localizations and end-to-end tests reflect the new support.

Changes

GeoParquet STAC support

Layer / File(s)	Summary
STAC asset formats and URL resolution packages/plugins/src/plugins/stac-api.ts, tests/stac-api.test.ts	STAC assets accept Azure storage metadata. S3 and Azure object-store URLs are normalized. Fetchable Parquet assets are recognized and visualized.
MapLibre visualization and localized messages packages/plugins/src/plugins/maplibre-stac.ts, apps/geolibre-desktop/src/i18n/locales/*.json	The plugin signs Azure Blob URLs when required and loads GeoParquet with addVectorLayerFromUrl. Unsupported-asset messages list GeoParquet.
STAC panel end-to-end checks e2e/stac-api-panel.spec.ts, e2e/stac-pmtiles.spec.ts	The panel test expects Parquet assets to be addable. The PMTiles test selects the PMTiles asset explicitly.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to fea25

This change adds GeoParquet STAC asset support and updates related localized messaging; no actionable merge-blocking risk remains beyond normal checks and review.

Poem

I’m a rabbit with a map in my paw,
GeoParquet hops through every draw.
Azure paths get signed with care,
Vector layers bloom from there.
“Add” now welcomes formats new—
I twitch my nose and bid review!

Code review

Bugs

• None found beyond the persistence issue noted under Security — the switch/case routing, browserAssetHref's new Azure branch, and readableHref's fallback-to-unsigned behavior all look logically sound and match their test coverage. Confidence: high.

Security

• packages/plugins/src/plugins/maplibre-stac.ts:574-615 — The SAS-signed href (with an expiring Planetary Computer token) is used directly for the pmtiles, cog, and parquet branches of visualizeAsset, and each of those persists its source URL into the store/project (createPMTilesStoreLayer's url/sourcePath, the raster control's synced source, the vector control's synced source). The geojson branch explicitly avoids this by keeping asset.href (unsigned) for provenance, but that protection isn't applied to the other three formats, which all go through the same signer. This risks embedding a live-but-short-lived credential in a saved/shared project file, and causes the layer to silently fail to reload once the token expires. Confidence: medium-high.

Performance

• No issues found. The signing call is cheaply short-circuited for non-Azure hrefs, and the dynamic import of maplibre-gl-planetary-computer is memoized. Confidence: high.

Quality

• packages/plugins/src/plugins/stac-api.ts:586-620 — StacAssetDisplayFormat is now a plain alias of StacAssetFormat, and assetFormat is a pure pass-through to assetDisplayFormat; the two no longer diverge now that parquet is addable, so the split reads as vestigial. Not incorrect, just a minor readability nit. Confidence: low.
• The new signing/persistence logic in maplibre-stac.ts (readableHref, planetaryComputerSigner, the pmtiles/cog/parquet branches) has no test coverage — only the pure stac-api.ts helpers (browserAssetHref, isAzureBlobHref) gained tests. The persistence issue above wouldn't be caught by the existing suite. Confidence: medium.

CLAUDE.md

• No violations found. Locale updates cover all shipped catalogs consistently, the CSP already allows https: broadly so no Tauri allowlist change was needed, and the new dependency (maplibre-gl-planetary-computer) is properly declared in packages/plugins/package.json. Confidence: high.

[github-actions]

Code review

Bugs

• packages/plugins/src/plugins/maplibre-stac.ts:583-614 — The geojson branch deliberately keeps the unsigned href as provenance so an expiring SAS token doesn't get saved into the project, but the pmtiles and cog branches pass the signed href straight into addPMTilesAsset/addCogLayer, both of which persist the URL verbatim as the layer's source. Planetary Computer tokens expire within the hour, so a PMTiles/COG asset added from a private collection bakes an expiring token into the saved project — it will silently stop loading later with no easy recovery. Confidence: medium-high (posted inline).
• packages/plugins/src/plugins/maplibre-stac.ts:946 — The Download button opens selected()[1].href (the unsigned href), while Add now signs the same href via readableHref for exactly the Planetary Computer collections this PR targets. So Add will succeed and Download will 409 for the same GeoParquet assets. The line itself isn't in the diff, so GitHub wouldn't let me anchor an inline comment there, but the PR is what makes this asymmetry reachable for a real (previously unaddable) asset class. Confidence: medium.

Security

• packages/plugins/src/plugins/maplibre-stac.ts:565-572 — readableHref signs any href whose hostname ends in .blob.core.windows.net by calling Microsoft's Planetary Computer SAS-token endpoint, regardless of whether the connected catalog is actually Planetary Computer. A third-party STAC catalog that happens to host assets on Azure Blob Storage would have its item collection ID and blob path sent to planetarycomputer.microsoft.com on every Add. It fails closed (falls back to the unsigned href on error), so impact is low, but it's an unconditional third-party network call driven only by a hostname pattern match. Confidence: low-medium.

Performance

• Nothing significant beyond the minor point above (an unnecessary signing round-trip is attempted even for unsupported/null-format assets, since readableHref runs before the format switch). Confidence: low, not worth a fix on its own.

Quality

• No unit or e2e test exercises readableHref/planetaryComputerSigner (the actual SAS-signing logic) — the new tests only cover the pure href-resolution helpers in stac-api.ts. Given this touches an external dependency (maplibre-gl-planetary-computer) and a real failure mode (item lacks collection, signing throws, etc.), some coverage of visualizeAsset's signing path would help. Confidence: medium.
• Everything else — the assetFormat/assetDisplayFormat simplification, the Azure href resolution (browserAssetHref, isAzureBlobHref), the i18n string updates across all locales, and the e2e test adjustments — looks correct and consistent with the STAC helpers' existing conventions.

CLAUDE.md

• No violations found: no new external map/tile host needed adding to the Tauri CSP allowlist (Planetary Computer signing is same-origin fetch to Microsoft's API, not a map/tile style host), and the i18n catalog updates follow the existing en.json-source-of-truth pattern across all locale files.

Code review

Bugs

• packages/plugins/src/plugins/stac-api.ts:164 — When an Azure-scheme (abfs:///az:///abfss://) asset has no resolvable table:storage_options.account_name, browserAssetHref leaves the href as a raw abfs://… URI. Since format detection only looks at media type/extension, the STAC panel still marks the asset addable and enables Add; clicking it hands a non-http(s) URL to addVectorLayerFromUrl, which expects http(s). Likely a silent failure instead of a clear "not addable" state. Confidence: medium.

Security

• None found. SAS token signing goes through the existing maplibre-gl-planetary-computer library, tokens are minted per-add (not persisted to the project file) for the GeoParquet path only, and signing failures fall back gracefully to an unsigned fetch rather than throwing unhandled. isAzureBlobHref's suffix check is correctly anchored (verified against the added test for a spoofed-suffix host) so it can't be tricked by a hostname like notblob.core.windows.net.evil.com.

Performance

• None found. The SAS token manager is lazily imported and cached (sasManager ??= …), avoiding duplicate imports on concurrent calls, and only re-imports after a genuine failure.

Quality

• packages/plugins/src/plugins/stac-api.ts:618 — Minor, non-blocking: StacAssetDisplayFormat is now a pure alias of StacAssetFormat and assetFormat is a passthrough to assetDisplayFormat; the explanatory comment suggests this seam is intentional for future-proofing, so likely fine as-is. Also, the new itemAccount (item-level table:storage_options) fallback path in normalizeItem isn't covered by a dedicated test — only the asset-level override is exercised. Confidence: low.

CLAUDE.md

• All 19 locale files were updated consistently with en.json for the addUnsupported string; no locale was missed. No other CLAUDE.md-tracked mirrors (Whitebox catalog, MAX_VECTOR_PMTILES_ZOOM, MAX_VECTOR_BYTES, control-selector mirrors) are implicated by this change.

[github-actions]

Code review

Bugs

• High confidence — packages/plugins/src/plugins/maplibre-stac.ts:609: the SAS-signed URL from readableHref is passed to addVectorLayerFromUrl, and createVectorStoreLayer (vector-layer-sync.ts:142-198) persists that exact URL as layer.source.url/sourcePath into .geolibre.json. restoreVectorLayers (maplibre-vector.ts:333-345) replays layers by refetching the persisted URL verbatim, without re-signing. This contradicts the PR's own doc comment claiming only PMTiles/COG bake an expiring token into the saved project — vector/GeoParquet URL-sourced layers do the same. A project saved with a private Planetary Computer GeoParquet asset will fail to reload that layer once the ~1‑hour SAS token expires. Posted inline.
• Medium confidence — packages/plugins/src/plugins/maplibre-stac.ts:949 (unchanged line, outside the diff so no inline comment could be attached): the Download button still opens the raw unsigned asset.href, while Add now signs the same href for parquet. For the private PC containers this PR's own comment describes (409 without a token), Add will succeed and Download will fail on the identical asset — a confusing asymmetry.

Security

• No issues found. The already-existing credential-redaction pass (packages/core/src/credentials.ts) explicitly strips Azure SAS query parameters (sig, se, sp, sv, sr, st, skoid) from layer.source/sourcePath on export/share, so the SAS token introduced here won't leak through that path — only the plain local save/reload path (noted above) is affected.

Performance

• No notable issues. Token minting is cached per collection by the upstream SASTokenManager, and the maplibre-gl-planetary-computer import is lazy and memoized like the existing maplibre-gl-vector pattern.

Quality

• Low confidence — the new signing/persistence logic (readableHref, planetaryComputerSigner) has no direct unit test (no tests/maplibre-stac*.test.ts), unlike the well-covered stac-api.ts changes; a test exercising the signer-failure fallback path would have caught the persistence issue above.
• Low confidence — maplibre-stac.ts now statically imports addVectorLayerFromUrl from ./maplibire-vector, pulling that module's graph into the STAC plugin bundle eagerly (though the heavy maplibre-gl-vector library itself stays lazily imported inside it).

CLAUDE.md

• No violations noted; locale files, e2e specs, and format-mirroring conventions all appear consistently updated.

[github-actions]

Code review

Bugs: None found. The href resolution (browserAssetHref, isAzureBlobHref), the fetchability gating (isFetchableHref), the exhaustive visualizeAsset switch, and the item/asset-level table:storage_options fallback all handle their edge cases correctly (missing account name, substring-spoofed hostnames, non-http protocols, unresolved object-store URIs). Confidence: high.

Security:

• The signed Planetary Computer SAS URL gets persisted verbatim into the project (source.url/sourcePath) and is never re-signed on restore — already acknowledged in the code's own comment, but it also means a project exported/shared shortly after adding the layer hands the recipient live read access to a possibly-private container for up to ~1 hour, not just a layer that later breaks. Worth a tracking issue. Confidence: low-medium.

Performance:

• addVectorLayerFromUrl is called without an ingestMode, unlike the two existing callers for the same file type (huggingface, source-coop), which default it to "table" explicitly and expose a "stream" choice in their UI. STAC-served GeoParquet can be large, and this panel has no way to stream it in place — every asset is fully materialized into DuckDB. May be intentional for a first cut, but worth confirming. Confidence: medium.

Quality:

• The core new feature — actually clicking Add on a GeoParquet STAC asset — has no automated test coverage. tests/stac-api.test.ts only covers href resolution/format detection, and the one e2e spec touching a parquet asset (e2e/stac-pmtiles.spec.ts) explicitly switches away from it to test PMTiles instead. visualizeAsset's "parquet" branch and the SAS-signing path (readableHref, planetaryComputerSigner) are exercised by nothing. Confidence: medium.
• Everything else (i18n locale updates, assetFormat/assetDisplayFormat type consolidation, e2e label update) is consistent and complete across all 19 locale files.

CLAUDE.md: No violations — the new maplibre-gl-planetary-computer dependency was already declared in packages/plugins/package.json by an earlier, unrelated plugin, so nothing needed updating here; the Tauri CSP's connect-src already allows all https: origins, so no allowlist change was required for the new Azure blob / SAS-signing traffic.

Code review

Security

• readableHref's SAS-signed URL for Planetary Computer GeoParquet assets gets persisted verbatim into the project's source.url/sourcePath. A shared/exported .geolibre.json project carries a live (if short-lived) credential to a private Azure container. Already acknowledged in the code's own comment but not mitigated. (medium confidence) — inline comment posted on packages/plugins/src/plugins/maplibre-stac.ts:569-583.

Bugs

• Same root cause as above: since the SAS token is minted once at add-time and never re-signed, a restored project's Planetary Computer GeoParquet layer silently stops loading after ~1 hour with no indication the failure is due to an expired token rather than a generic load error. Documented as a known follow-up, not fixed here. (medium confidence, same inline comment)
• No functional bugs found in the new href-resolution logic (browserAssetHref's S3/Azure branches, isAzureBlobHref, isFetchableHref) — traced through the canonical/shorthand ABFS forms, the table:storage_options fallback from item→asset, and the new assetFormat scheme restriction; all match the accompanying tests, which cover the relevant edge cases (missing account, canonical host with no container, substring-spoofed hostnames, etc.). (high confidence, no issue)

Performance

• None found; the SAS token manager is cached (sasManager) and only invoked at add-time for Azure-hosted parquet assets, avoiding repeated signing calls.

Quality

• The new readableHref/SAS-signing path in maplibre-stac.ts has no unit test coverage (only the pure stac-api.ts href-resolution helpers are tested); verification relied on manual testing per the PR description. Understandable given it wraps a dynamically-imported third-party token service, but worth noting as a coverage gap. (low confidence, not inline — minor)
• Minor UX note: since GeoParquet assets are now addable, the panel's "preselect first addable asset" heuristic can now default to a dataset-root GeoParquet/metadata asset (often listed first in a STAC item's asset map) ahead of the item's primary imagery/vector asset. Not a bug — same heuristic as before, and the e2e test update shows the author is aware — just a possible behavior surprise worth a note. (low confidence, not inline)

CLAUDE.md

• All 19 shipped locale catalogs were updated consistently for the new addUnsupported string, matching the i18n convention (en.json as source of truth, t()-driven strings). No violations found.
