These element types produced large grey boxes obscuring the building in
renders of models that contain space volumes or annotation geometry
(e.g. 2D floor-plan drawings stored as Body CSG). Other IFC viewers
(Bonsai, web viewer) suppress these types in 3D views by default.

Forgejo editor previews (non-contenteditable) were being modified by
linkifyBareIfcUrls and replaceIfcAnchors, corrupting the editor state.
Restrict both functions to .markup containers (rendered issue/wiki/README
content) so editor UI is never touched.
Forgejo's WYSIWYG editor uses a contenteditable div. Walking text nodes
inside it caused linkifyBareIfcUrls to split [label](ifc://...) by wrapping
just the URL in an anchor, which the editor serialised back as [label]().
Commit 4b53dfe replaced the Go goldmark extension with JS text-node
linkification, making bare ifc:// URL rendering work entirely client-side.
No Forgejo rebuild is needed for any feature.
- Remove "Optional: Go patch" section from README.md
- Remove Go tests from Development section
- Update forgejo/README.md feature table, prerequisites, and deploying sections
- Remove "Applying the patch", "Configuration" (PREVIEW_SERVICE_URL), and
"Upgrading Forgejo" (Go-specific steps) sections from forgejo/README.md
- Update forgejo/SETUP_LOCAL.md: bare URLs now work; remove Step 6 (app.ini)
- Delete forgejo/go.patch (dead code — ifc_url.go was removed in 4b53dfe)
- Add underscore caveat note wherever bare URL support is described
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Bare URLs with paired underscores in the path/query (e.g. _model_v2.ifc)
are split by Goldmark's emphasis parser into <em> tags, breaking the JS
text-node linkifier. Workaround: use the [label](ifc://...) link form.

web-ifc disposes its IfcAPI after load so context filtering must happen
before the buffer reaches ifcLoader.load(). Pre-process the IFC-SPF buffer
to find IfcGeometricRepresentationSubContext entities with ContextIdentifier
'Clearance', then empty the items list of any IFCSHAPEREPRESENTATION that
references those contexts, so door-swing and equipment-clearance volumes
produce no geometry.

- Inline script at top of <body> creates the snapshot overlay immediately
on page load, before the deferred module script runs, eliminating the
black flash between navigation and overlay appearance
- Save a JPEG snapshot to sessionStorage before navigating to a new ref;
the overlay covers the blank WebGL canvas while the model reloads
- Fade the overlay out after two animation frames post-load so the canvas
has painted before the transition begins
- Reload on pageshow with persisted=true: bfcache restore left the WebGL
canvas blank and skipped the inline script; a fresh reload lets the
snapshot overlay work correctly
- Replace native <datalist> ref picker with a custom dropdown; the native
datalist won't open programmatically via .focus() in most browsers

When the ifc:// URL is edited and Enter pressed, capture toRawUrl() of
the loaded model at load time. On any subsequent loadUrl() call, compare
against that snapshot: if the raw file URL is unchanged, call the new
applyViewChanges() function in-place instead of navigating to a new page.
applyViewChanges() diffs old vs new URL query params and applies only what
changed: camera position (with cameraControls.update(0) flush before
render), FOV/scale, clipping planes, selector/visibility, and query. A
full page reload now only happens when host, repo, ref, or path changes.
Fixes ifcurl-ntm.

web-ifc's COORDINATE_TO_ORIGIN=true shifts all model geometry so the first
element lands at origin (≈12m shift for simple-ifc). GetCoordinationMatrix
returns identity despite the shift, so engine_fragment can't compensate.
Camera URLs are in IFC world coords (per spec §5), but the model was in
shifted coords, causing the JS viewer and Python renderer to disagree.
Set COORDINATE_TO_ORIGIN: false in ifcLoader.setup() so model geometry
stays in IFC world coords, matching what IfcOpenShell outputs.

GitPython raises a plain ValueError from _parse_object_header when a commit
hash is missing, not BadObject, so the previous message-based retry guard
("not found in repository") never matched. Broaden the except clause to catch
(ValueError, BadObject, BadName) and drop the fragile string check. Extract
the fetch logic into _fetch_all_refs helper and apply the same retry to
diff_text. Add tests covering _fetch_all_refs, the retry-on-BadObject path,
and the no-retry-for-local-transport invariant.

ifcurl.js: URL-pattern cases (PR diff, commit page) now run before
the DOM-based file-view case, which also matches on Forgejo diff pages
and was causing an early return that skipped PR diff rendering.
git.py: fetch_ifc now retries with a full ref fetch when an immutable
ref (commit hash) is not found in the cached clone — PR branch commits
are absent from the initial default-branch clone and need a fetch.

viewer-url.js: parseIfcUrl returns query field; buildIfcUrl gains optional
fifth query param, included in the QS when non-empty.
viewer.html: add 'query' text field (label + input) in toolbar row 2
after the visibility selector. Add #query-panel (fixed bottom-centre)
with a scrollable table showing GlobalId | value rows, a header
displaying the query path, and a close button.
viewer.js: populate queryInput from parsed URL on load; include query
in buildIfcUrl() wrapper; wire queryInput into Enter-key and focus/blur
listeners. Add applyQuery(srcUrl, queryPath) which calls GET /query,
populates the table, and shows the panel. Called from main() after
applySelector when both selector and query params are present.
viewer-url.test.js: add tests for parseIfcUrl query field, buildIfcUrl
with query, and buildIfcUrl omitting empty query.

viewer.html: add 'clash' option to the visibility <select> dropdown.
viewer.js: add clash branch in applySelector for both the simple
type-selector path and the complex server-side GUID path. Selected
elements are coloured 0xdc3232 (red, matching render.py's _CLASH_COLOR);
non-selected elements remain at their normal material colours, consistent
with highlight mode behaviour.

render_service.py: _sandboxed_clash(ifc_bytes, selector_a, selector_b) uses
ifcopenshell.geom.tree.clash_collision_many for hard-clash detection (mesh-
level interpenetration, touching excluded). When selector_b is None, tests
set A against all other IfcProduct elements. Deduplicates pairs via frozenset.
render_service.py: /clash endpoint wraps _sandboxed_clash in the sandbox.
service.py: ClashRequest model, _clash_via_socket() for socket delegation,
and GET/POST /clash endpoints. URL selector= is set A; optional selector_b
body/query param is set B. Returns {"pairs": [["guidA", "guidB"], ...]}.
Reuses Tier 2 byte cache.
https://claude.ai/code/session_01NBsytCd6L7UQPiKbcLn4kn
render.py: add _CLASH_COLOR and clash branch in _add_shape — selected
elements rendered in red, non-selected in normal material colours.
render_service.py: add _sandboxed_query(ifc_bytes, selector, query_path)
and /query endpoint. Dot-notation query_path splits into pset/property
(Pset_WallCommon.FireRating) or falls back to direct IFC attribute (Name).
Returns {GlobalId: str(value)}, excluding None and entity references.
service.py: add QueryRequest model, _query_via_socket() for socket

Installs bd (beads issue tracker) via go install and bootstraps the
embedded Dolt database from the git-tracked issues.jsonl on each fresh
web session, where the embeddeddolt/ directory is absent.
Bootstrap sequence:
1. go install github.com/steveyegge/beads/cmd/bd@latest (if absent)
2. Temporarily point sync.remote to the HTTP git origin so bootstrap
can create the embedded Dolt schema (Dolt wire-protocol clone fails
over HTTP/1.1 but that is expected and handled)
3. Restore .beads/config.yaml and .beads/issues.jsonl from git before
any bd auto-export can overwrite them
4. bd config set issue_prefix ifcurl triggers auto-import of the full
issues.jsonl into the initialised but empty database
Also adds bd to PATH via CLAUDE_ENV_FILE and sets beads.role=contributor
to suppress the role-not-configured warning.

BCF list_topics now maps topic_status, assigned_to, label, modified_after,
modified_before query params to Forgejo issue API params.
documents_api adds GET /document-metadata/{document_id} which decodes the
document_id and proxies Forgejo's contents endpoint for file metadata.

POST /documents/1.0/document-versions resolves document_ids (base64url
encoding of owner/repo/path) to versioned download URLs. Exposes only
git tags + the current HEAD commit — mirrors CDE conventions where only
released versions are visible, while still surfacing the WIP state.
version_number is the tag name for releases and short SHA for HEAD.
Tagged SHAs are deduplicated so HEAD at a tag doesn't create a duplicate.
Download URLs point at Forgejo's existing raw/commit endpoint.
Auth forwarded verbatim. No Go code, no Forgejo recompilation.
Proxy at /documents/ on the Forgejo hostname.

Returns the Foundation API 1.1 version document listing BCF 3.0 and
Documents 1.0 API base URLs. Public, no auth required. Derives the
public base URL from X-Forwarded-Host/X-Forwarded-Proto headers so it

Implements SPECIFICATION.md §6 BCF→ifc:// direction: parse a BCF 3.0
REST viewpoint dict (camera, clips, selection/visibility) and apply it
to a base IfcUrl to produce an ifc:// URL string.
IfcUrl.to_string() serialises any IfcUrl back to a valid ifc:// URL,
enabling round-trip parse→to_string for all URL forms.

Bundle OBCF (components-front) alongside OBC so Highlighter is sourced from the

On /src/commit/{hash}/file.ifc pages, breadcrumb anchors match the
a[href*="/src/commit/"] selector before the Permalink anchor, returning
a directory URL that parseCommitHref rejects (no file path). Fix by
trying window.location.pathname first — it parses correctly when already
on a commit file URL — and only falling back to a Permalink anchor search
for branch/tag file views. Add a regression test for directory-level
commit hrefs returning null.

Extract parseCommitHref, isSimpleTypeSelector, subtractIdMap, and
isCommitHash into a new viewer-util.js ES module so they can be tested
without a browser. Convert ifcurl.js from an IIFE to an ES module
importing from viewer-util.js; update footer.tmpl to type="module".
Add node:test suites for viewer-url.js (32 tests) and viewer-util.js
(28 tests). Add npm test script and document it in the build section.

- Types panel: fix count by iterating groupData directly (groupData.map
was undefined — FragmentIdMap is the groupData value, not a wrapper)
- Clip planes: register OBC.Raycasters for the world before setupClipper
so clipper.create(world) can raycast against the model surface
- Ref navigation: ▾ button now navigates when input already has a value;
add change listener alongside input for cross-browser datalist coverage
- Orthographic projection: replace missing controls.setOrthoCamera() with
world.camera.projection.set("Orthographic") + threeOrtho scale fix;
refresh threeCamera reference after projection switch
- BCF export: capture rendererCanvas snapshot and include snapshot.png in
the BCF zip with a <Snapshot> reference in markup.bcf

- visibility=highlight: apply orange colour overlay to selected elements
(all others visible normally) using FragmentsManager.highlight() directly
— OBC.Highlighter is in @thatopen/components-front which is not installed
- visibility=ghost: dim non-selected elements to 15% grey opacity
- visibility=isolate: unchanged (hider.isolate)
- Add 'show' dropdown (highlight/ghost/isolate) that appears when a
selector is set; changing it reloads with the new visibility= param
- Add 'fit' button: calls cameraControls.fitToBox(model.box, true)
- Smooth load transition: capture canvas snapshot (preserveDrawingBuffer)
before navigation, display it as an overlay on the new page, fade it
out once the model has rendered
