fix(viewer-embed): route ISOLATE through the assembly-expansion resolver, and gate every future channel (#3338)#3389BIMvoice wants to merge 4 commits into
Conversation
…ver, and gate every future channel (#3338) The embed bridge's ISOLATE postMessage command called isolateEntities() with the parent's raw ids, bypassing cameraCallbacks.resolveHighlightIds -- a sixth channel with the #2531/#2532 shape: isolating a geometry-less IfcElementAssembly by ref blanked the embed. It shares apps/viewer's store and Viewport (vite.config.ts's `@` alias), so the resolver was already reachable; the fix routes through it like the other five channels. Adds scripts/check-isolate-expansion-routing.mjs (Node tests, CI) so a future channel that forgets the expansion fails loudly instead of shipping a blank viewport: every isolateEntities( call site under apps/viewer and apps/viewer-embed must route through the resolver or be allowlisted with a reviewable reason. RED-proven both directions (an unlisted new call site, and a known channel that lost its resolver call) against synthetic fixtures in check-isolate-expansion-routing.test.mjs, and by hand against the real tree (planted + removed, and LensPanel.tsx's resolver call stripped + restored by SHA). Builds alongside open PR #3382 (the SDK/MCP isolate() instance fix, a different channel) rather than duplicating it. Claude-Session: https://claude.ai/code/session_01QPHChk3Ve9N519A4kY7436

…versarial review found in the isolate-expansion gate (#3338) Two silent bypasses in check-isolate-expansion-routing.mjs let a channel skip assembly-expansion routing without failing CI: 1. CALL_PATTERN only matched the literal `isolateEntities(` token, so a destructured, renamed store binding (the ordinary Zustand shape `const { isolateEntities: applyIsolation } = useViewerStore()`) never registered as a candidate at all -- not even counted toward candidateCount. Added ALIAS_DESTRUCTURE_PATTERN as a second signal so any destructuring of the isolateEntities key, aliased or not, is treated as a candidate. 2. NO_MARKER_REQUIRED reasons were only checked by this gate's own test (an assertion about the two entries that happened to exist), not by classifyFile -- a junk reason like ['some/File.tsx', 'x'] passed CI clean. classifyFile now rejects a NO_MARKER_REQUIRED entry whose reason is not a real justification (isSufficientAllowlistReason). Also: walk() swallowed per-directory readdirSync errors with `catch { return; }`, making one unreadable subtree indistinguishable from a clean one. It now records the error as a gate failure instead. Finding 3 (marker checked file-wide, so a second unrouted call in an already-allowlisted file passes) is left open: every real routed file's marker-to-call gap ranges from a few lines up to ~77 lines across large comment blocks, so a proximity heuristic tight enough to catch a nearby bypass would false-fail the existing compliant call sites. Documented in the module's LIMITATIONS section; not attempted here. Both new failure modes are RED/GREEN tested against synthetic fixtures, including the exact bypass shapes an adversarial review demonstrated, plus a live on-disk plant/remove proof of the alias bypass against the real tree. The gate still hard-fails on zero roots, zero files, and a candidate count below the floor, and still passes clean on the real tree (956 files scanned, 6 channels, 4 routed + 2 exempt-with-reason).

Detect let and var destructuring aliases.
ALIAS_DESTRUCTURE_PATTERN only matches const. A file can use let { isolateEntities: applyIsolation } = useViewerStore() and then call applyIsolation(rawIds). classifyFile then marks the file as a non-candidate, so the gate does not detect the unrouted isolation channel.
Match all declaration kinds. Add a RED fixture for the let form.

… spot the gate had, and route the seventh channel plus its audited siblings (#3338) An adversarial review of the just-hardened isolate-expansion gate found a seventh channel it still could not see: `useEmbedUrlParams.ts`'s `?isolate=` handler calls `setIsolatedEntities(`, the visibility slice's ASSIGNING sibling of `isolateEntities` (which TOGGLES), never the token the gate watched. `grep -c "isolateEntities("` on that file was 0 -- it isolated raw ids from an embed URL param with no assembly-expansion routing at all, reproducing the #2531/#2532 blank-viewport bug for real, on main. check-isolate-expansion-routing.mjs: - Added SET_ISOLATED_CALL_PATTERN and widened CALL_PATTERN detection (and ALIAS_DESTRUCTURE_PATTERN) to cover both raw-isolation actions (RAW_ISOLATION_ACTIONS), so a channel can no longer dodge the gate by picking whichever sibling action isn't watched. - Audited every other direct setIsolatedEntities caller found by the widened scan and classified each: - useEmbedUrlParams.ts, useBCF.ts, useIDS.ts (installFocusIsolation / installSetIsolation), usePreviewIsolation.ts: genuinely raw, user- or externally-sourced ids -- added to REQUIRES_ROUTING_MARKER and fixed (see below). - useClash.ts: NO_MARKER_REQUIRED -- a clash pair's ids are always geometry-bearing by construction (clash detection tests mesh triangles), never a raw user pick. - tours/ids.ts: NO_MARKER_REQUIRED -- only ever calls setIsolatedEntities(null), a pure clear with nothing to expand. - visibilitySlice.ts itself (the actions' definition site) started matching on a doc-comment mention of setIsolatedEntities(null) -- NO_MARKER_REQUIRED, not a caller. - CANDIDATE_FLOOR raised 6 -> 13 to match the widened scan's real count. Fixes (all: `cameraCallbacks.resolveHighlightIds?.(ids) ?? ids` before assigning, same pattern as the embed bridge's ISOLATE command): - apps/viewer-embed/src/components/useEmbedUrlParams.ts: `?isolate=` ids. - apps/viewer/src/hooks/useBCF.ts: a BCF viewpoint's visible-component guids (not guaranteed geometry-bearing in this renderer). - apps/viewer/src/hooks/useIDS.ts: the row-focus isolate and the isolate-failed/passed/involved set-level isolate (ids an IDS specification's applicability filter matched, which can be any IFC class). - apps/viewer/src/components/viewer/anonymized-export/usePreviewIsolation.ts: the 3D export preview (includedIds is not restricted to renderable leaf types). Tests: two new EmbedViewer.urlParams.test.ts cases prove both directions (assembly expands via a registered resolver; falls back to raw ids with none registered) through the real store/hook, matching the existing ?isolate= test style. A new useIDS.isolate-expansion.test.tsx does the same for installFocusIsolation/installSetIsolation through the real useIDS() hook. check-isolate-expansion-routing.test.mjs gained a "seventh channel" suite covering the widened patterns, the new allowlist entries, and that setIsolatedEntities(null) alone still requires triage rather than being exempt by pattern-matching its argument. A live plant/remove proof against the real tree (the exact useEmbedUrlParams.ts and a bare setIsolatedEntities( bypass) failed before removal and passed clean after, both directions. useBCF.ts and usePreviewIsolation.ts have no dedicated behavioural test today (no existing harness for BCF viewpoint isolation or the export preview's resolver path); verified instead via the unchanged existing regression suites passing (18/18 anonymized-export, unaffected) and a full apps/viewer `tsc --noEmit` pass.

Parse code before accepting a routing marker.
ROUTING_MARKERS matches comments and string literals. A required channel can retain // cameraCallbacks.resolveHighlightIds(ids) after removing the real resolver call, while isolateEntities(rawIds) remains active. classifyFile() then returns ok: true, so CI does not detect the lost routing and a geometry-less IfcElementAssembly can blank the viewport again.
Tokenize or parse the source before checking markers. Add RED fixtures for commented and quoted marker-shaped text.

…sibling isolate() channel louistrue's #3382 ruling ("visibility-adapter.ts:99 guards an absent resolver but not an empty result") applies verbatim to five more resolveHighlightIds call sites that copied the same `resolveHighlightIds?.(ids) ?? ids` shape, all found on this branch (fix-3338-isolate-expansion-gate / #3389): - useIDS.ts: installFocusIsolation and installSetIsolation - useBCF.ts: the visibleGuids isolation-mode branch - usePreviewIsolation.ts (anonymized-export preview) - useEmbedUrlParams.ts (?isolate= URL param) `??` only falls back when the resolver is ABSENT. Viewport's resolveHighlightIds returns [] whenever geometryRef.current is null (renderer initialised, geometry not yet loaded) or every id resolves geometry-less; each of these five sites then assigned an empty set, hiding the entire model exactly like the visibility-adapter case. Fixed all five with the same union pattern LensPanel/PropertiesPanel/ SearchModal already use: `new Set([...resolved, ...rawIds])`, which degrades to the raw ids when resolved is empty (absent or genuinely empty) and is a harmless superset when the resolver expands an id. Updated existing assertions in useIDS.isolate-expansion.test.tsx and EmbedViewer.urlParams.test.ts for the new union (the raw pre-resolution id now stays in the isolated set alongside the resolved parts), and added the previously-missing empty-resolver-result case to both files (RED without the fix, GREEN with it -- proved separately per file below). useBCF.ts's and usePreviewIsolation.ts's isolate paths had no existing test coverage to extend.

The gate is genuinely good. The routing repeats #3382's empty-result bug in six places, and one of them is a regression against what the code did before. The gate first, because it is the valuable half and it holds up. I verified it by exit code rather than by its output: clean tree exits 0; a planted unlisted The problem. Every routed site uses the same shape: const ids = resolveHighlightIds?.(raw) ?? raw;
Empty is reachable: Concrete failing input: an embed
Fix, the repo's own established pattern. LensPanel and PropertiesPanel both union, and LensPanel's comment says verbatim that isolating an empty set would hide the entire model: [...new Set([...(resolveHighlightIds?.(raw) ?? []), ...raw])]For the Set-valued sites, Then one test where the resolver returns Ordering with #3382. They are complementary, zero file overlap, and I simulated both orders — the gate exits 0 with and without #3382's adapter in the tree, so neither order breaks CI. Take #3382 first (it needs the same empty-result fix), then this.

Summary
Addresses the systemic half of #3338 — "expansion is one call site every channel must remember to use" — alongside #3382, which fixed the newest instance (the SDK/MCP
isolate()channel). This PR:Finds and fixes a sixth channel
#3382itself didn't enumerate:apps/viewer-embed/src/bridge/handler.ts'sISOLATEpostMessage command calledstate.isolateEntities(payload.ids)with the parent's raw ids, never routing throughcameraCallbacks.resolveHighlightIds. The embed app sharesapps/viewer's store and Viewport (apps/viewer-embed/vite.config.ts's@alias resolves@to../viewer/src), so the resolver was already reachable — nothing structural stopped this, exactly the "one call site every channel must remember to use" shape. Isolating a geometry-lessIfcElementAssemblyby ref over the embed's postMessage API blanked the viewport, the same fix(viewer): frame, list and count element assemblies whose geometry lives on aggregated parts #2531/feat(viewer): "Isolate in 3D" applies the advanced filter's result to the model #2532 failure mode.Adds the systemic gate:

It scans every.ts/.tsxfile underapps/viewer/srcandapps/viewer-embed/srcfor a call toisolateEntities(and requires each one to either:resolveHighlightIds/expandToGeometryBearingIds/expandFilterRowsThroughAggregationin the same file (REQUIRES_ROUTING_MARKER), orNO_MARKER_REQUIRED) — used forHierarchyPanel.tsx(a genuinely different, already-verified mechanism: its class/type/group tabs isolate idstreeDataBuilder.tspre-expanded at tree-build time viahasAggregatedGeometry/collectAggregatedDescendants) and, temporarily,visibility-adapter.ts(tracked by fix(viewer): route SDK isolate() through the assembly-expansion resolver (#3338) #3382, not duplicated here — see below).A file calling

Extending assembly expansion there would be a new feature, not a regression of this mechanism.Mechanism chosen, and why
Preference order per the task was (1) impossible to forget, (2) fail loudly, (3) not a comment. (1) doesn't fit:
expandToGeometryBearingIdsneeds a renderer-filtered geometry predicate (hasGeometry, backed byViewportContainer'sfilteredGeometry) and a per-model relationship-graph accessor — neither is available insidevisibilitySlice.ts'sisolateEntitiesaction, which is a pure state setter with no renderer or data-store access. Moving that dependency into the store slice would be a real architecture change (store depending on renderer callbacks), which is what the issue's own "open question" (resolver property vs. explicit user action) is really asking, and that's a maintainer call, not mine to force. So (2): a gate, in the style ofcheck-refwalk-guards.mjs/check-loader-hook-specifier-match.mjs— known-list allowlist, structural/textual detection, anti-vacuity floor, and its own*.test.mjs.RED proof, both directions
