fix(server): promote a contained (not aggregated) spatial element into its own hierarchy node - #3973
Conversation
…o its own hierarchy node apps/server/src/services/data_model/spatial.rs built children_ids only from IfcRelAggregates, so an IfcSpace/IfcSpatialZone placed under its storey via IfcRelContainedInSpatialStructure only (the common Revit Family/Dynamo export pattern, #1075) never got its own SpatialNode - it was left as a flat leaf with no parent link, and anything it in turn contained was unreachable from the tree. Mirror packages/parser/src/spatial-hierarchy-builder.ts: a contained target that is itself a spatial-structure type is promoted into spatial_children_map instead of element_containment_map, deduped against an aggregates edge to the same parent so a doubly-linked space isn't built twice. Also close the type-list gap between Rust's is_spatial_type (14 types) and packages/data/src/spatial-types.ts's SPATIAL_STRUCTURE_TYPE_ENUMS (17): add IFCSPATIALZONE, IFCMARINEPART and IFCFACILITYPARTCOMMON, and extend the element_to_space bucket to treat IfcSpatialZone like IfcSpace, matching isSpaceLikeSpatialType.

…up cross-parent spatial children build_spatial_nodes_recursive had no visited set and no depth bound. This PR's own containment-promotion is the first place a cycle can form by mixing IfcRelAggregates and IfcRelContainedInSpatialStructure edges (e.g. Storey A aggregates Storey B while Storey B "contains" Storey A) - the resulting spatial_children_map cycle recurses without bound and, because this crate builds with panic = 'abort', SIGABRTs the whole process rather than raising a catchable panic. Add a visited set and a depth bound to the recursive walker, mirroring packages/parser/src/spatial-hierarchy-builder.ts's ctx.visited and MAX_SPATIAL_TREE_DEPTH in apps/viewer/src/utils/serverDataModel.ts. Separately, a space aggregated under one storey AND merely contained under a different storey produced two parents both listing it in children_ids while only one SpatialNode was ever built for it - which parent "won" depended on relationship-list/HashMap iteration order, not a rule, so a client walking from the other parent found a dangling reference. Assign each spatial child exactly one canonical parent up front: IfcRelAggregates (the canonical spatial-hierarchy relationship) always wins over a containment promotion, and ties within a kind resolve to first occurrence in file order, never a HashMap's iteration order. This also incidentally makes any reachable-from- project cycle in spatial_children_map structurally impossible (the guard above remains as defense in depth for a hand-built or future-introduced cycle that bypasses this relationship-derived map).

build_spatial_hierarchy's orphan-fill loop only checked nodes_map, which is empty both for an entity the depth-cap in build_spatial_nodes_recursive excluded and for one never reached at all (a descendant of an excluded node). It reinserted every such entity as a fake root (parent_id: 0, level: 0) with its real children_ids intact, so a node's own parent/level said "root" while its actual parent's children_ids still named it as a child - and the Parquet spatial export (services/parquet_data_model.rs), which reads parent_id as authoritative, would render a spurious extra root instead of the dropped subtree it actually is. Track which entities the recursive walk actually reached (including ones it excluded) via `visited`, and skip the orphan-fill for anything either visited or already claimed as someone's child in canonical_parent - only a genuinely unclaimed spatial entity is rescued as a root. Also strip a dropped child's id from its parent's own children_ids after the recursive descent returns, so no node ever references a child with no SpatialNode of its own. Added a regression test building a 110-level aggregation chain past MAX_SPATIAL_TREE_DEPTH (100): confirmed it fails on the pre-fix code (the depth-capped child remained in its parent's children_ids) and passes after the fix, with no dangling children_ids anywhere in the resulting tree. cargo test -p ifc-lite-server: 276 passed, 0 failed. cargo clippy -p ifc-lite-server -- -D warnings: clean. Claude-Session: https://claude.ai/code/session_01QPHChk3Ve9N519A4kY7436
Adds the direct check for the ordering claim in build_spatial_hierarchy's comments: the cross-parent dual-linked-space fixture, reordered (both IFCRELAGGREGATES lines swapped, and moved after the IFCRELCONTAINEDINSPATIALSTRUCTURE line), must produce an identical tree to the original ordering. It does - this is a confirming control, not a bug fix. cargo test -p ifc-lite-server: 277 passed, 0 failed. cargo clippy -p ifc-lite-server -- -D warnings: clean.

The aggregates branch has no dedup, so a repeated identical aggregation edge lists the child twice.
The containment branch at lines 147-149 checks children.contains(&rel.related_id) before pushing. The aggregates branch does not. If two IFCRELAGGREGATES name the same relating_id/related_id pair (or one aggregate repeats an id in RelatedObjects), the condition at line 121 holds for both rows and the child is pushed twice.
build_spatial_nodes_recursive builds one node for it (the second visit returns at line 331), so the parent's children_ids names a child id twice while only one SpatialNode exists. A client walking children_ids renders the space twice.

This fixture no longer builds a cycle, so the test cannot detect removal of the visited guard.
The doc comment states the fixture produces spatial_children_map == {A: [B], B: [A]}. Trace line 1033 through the new classification code in spatial.rs:
- Line 1031 (
#1aggregates#2) setscanonical_parent[2] = 1in the pre-pass at lines 106-112. - Line 1033 contains
#2under#3. Atspatial.rsline 142or_insertreturns the existing1, sowinner == 1 != 3and nothing is pushed.
spatial_children_map is {1: [2], 2: [3]} — acyclic. The canonical-parent rule alone prevents this cycle, so the test passes with or without the visited check at spatial.rs line 330. The direct unit test in spatial_tests.rs is the only real coverage for the visited set.
Either correct the comment to say the canonical-parent rule is what breaks this shape, or build a fixture the canonical-parent rule cannot flatten — for example two aggregation edges forming the cycle (#2 aggregates #3 and #3 aggregates #2, with neither reached from project first), so canonical_parent assigns 3 -> 2 and 2 -> 3 and both edges survive.

…Rust module-size ratchet spatial.rs had grown to 511 lines, tripping module_size_ratchet (400-line cap on non-generated .rs files) with no allowlist entry. Split along the seams the code and spatial_tests.rs already implied: - spatial_elevation.rs: IfcBuildingStorey.Elevation extraction with the ObjectPlacement Z fallback (extract_elevation_if_storey, extract_placement_elevation, and their attribute-index constants). - spatial_tree.rs: the cycle/depth-guarded recursive tree walk (build_spatial_nodes_recursive, MAX_SPATIAL_TREE_DEPTH). - spatial.rs: relationship-map construction (canonical_parent, spatial_children_map, element_containment_map) and the orphan-fill pass, now 315 lines. Pure refactor: no behavior change. cargo test -p ifc-lite-server: 277 passed before and after. Verified the depth-cap orphan-fill guard survived the split by temporarily reverting it (dropping the canonical_parent check in the orphan-fill loop) and confirming entities_past_the_depth_cap_are_dropped_cleanly_not_resurrected_as_fake_roots fails, then restoring it and confirming the suite passes again. Claude-Session: https://claude.ai/code/session_01QPHChk3Ve9N519A4kY7436
The orphan-fill loop in build_spatial_hierarchy skips an entity that has a canonical_parent, on the theory that it structurally belongs to a parent so leaving its subtree dropped is consistent. But when that parent is ITSELF an orphan rescued as a fake root, the loop populates the rescued node's children_ids straight from spatial_children_map with no filtering against nodes_map - unlike build_spatial_nodes_recursive, which strips exactly this shape from its own node after descending into its children. A Site never aggregated by Project (truncated/malformed export) gets rescued as a fake root, but still lists a Building it canonically parents in children_ids even though the Building - skipped by the canonical_parent check - never gets its own SpatialNode: the same dangling-reference shape this PR's own fix eliminated for the recursive-descent path, reappearing one level removed in the orphan-fill path. Add one final consolidation pass across all of nodes_map's children_ids after both the recursive walk and the orphan-fill loop have run, retaining only ids that resolved to an actual node - a no-op for recursively-built nodes (already filtered) and the fix for rescued ones. cargo test -p ifc-lite-server: 278 passed, 0 failed. cargo clippy -p ifc-lite-server --bins: clean. cargo test -p ifc-lite-processing --test module_size_ratchet: clean. node scripts/check-module-size.mjs: OK.
…ee (#3973) Two pointwise fixes landed for the same defect shape in this PR: a depth-capped entity resurrected as a fake root while a surviving ancestor still listed it, and (in b84197d) a rescued orphan's children_ids populated from spatial_children_map without filtering against nodes_map. Fixing the instance resets the clock; the shape - a dangling children_ids entry, or the two directions (children_ids / parent_id) disagreeing about who is whose child - can recur a third time in a different code path. Add spatial_hierarchy_consistency_violations (new spatial_invariant.rs, split out to stay under the 400-line module-size ratchet) checking, over every node in a finished tree: every children_ids entry resolves to a node, every parent_id resolves to a node or is the root sentinel (0), and the two directions agree - A.children_ids containing B implies B.parent_id == A and vice versa. That last clause is the one that actually catches the family: a fake root with a real parent_id mismatch passes the first two checks (it names no nonexistent id, and its own parent_id is the sentinel) while still being wrong. Wired into build_spatial_hierarchy itself via debug_assert! (a release build skips it, matching every other debug_assert! in this codebase), and into an extract_data_model_checked test wrapper that every existing spatial fixture in tests.rs now goes through unconditionally, regardless of build profile - so this retroactively guards every fixture already in the suite, not just a new one. Reproduced both historical instances by reverting each one's specific guard in isolation, confirmed the invariant fires, then restored: - Instance 2 (b84197d's consolidation pass disabled): the a_rescued_orphans_children_ids_never_names_a_node_that_was_not_itself_rescued fixture failed with "node #2 lists child #3 in children_ids, but no node #3 exists" - caught by the forward (dangling-reference) clause. - Instance 1 (5f2daac's orphan-fill skip condition and recursive retain-filter both reverted): the entities_past_the_depth_cap_are_dropped_cleanly_not_resurrected_as_fake_roots fixture failed with ten "node #N lists child #N+1 in children_ids, but #N+1.parent_id is #0 (expected #N)" violations - every resurrected id still resolved to its own fake-root node, so only the direction-agreement clause caught it; the forward-only clause would have passed. cargo test -p ifc-lite-server: 278 passed, 0 failed. cargo clippy -p ifc-lite-server --bins: clean. cargo test -p ifc-lite-processing --test module_size_ratchet: clean. node scripts/check-module-size.mjs, check-test-wiring.mjs, check-source-text-assertions.mjs: all OK.

A rescued orphan root's descendants are dropped rather than walked, and the new test accepts that outcome. The orphan-fill loop skips any entity that has a canonical_parent, even when that parent was never reached by the walk, so a descendant of a rescued root gets no SpatialNode. The retain pass then removes it from the rescued root's children_ids. The invariant holds, but the subtree is gone.

The second subsumes the first. Commenting out the per-node retain and running the suite gives 283 passed, 0 failed — no test distinguishes them. Commenting out the consolidation pass instead does fail ( The trap: each guard is individually removable without any test noticing, but removing both reintroduces the bug this PR fixed twice. A future reader tidying "dead code" would get a green suite either way. Options, in rough order of preference — all of them yours to pick, nothing has been changed:

Reviewed adversarially — clean, with one plausible follow-upReviewed this at head The promotion rule and its boundaries hold. Contained-and-spatially-typed promotes into The degenerate cases are genuinely covered, which is what I was most worried about given how often a value gets silently dropped in this area:
The split is extraction-only. No diff against the module-size ratchet or its allowlist; Mutation confirms the tests are load-bearing, not decorative. Forcing Full suite One follow-up, not a blockerThe This is reasoned from reading both implementations, not from running a matched fixture through both, and there is no test for the cross-parent case on either side (Rust has an order-independence control, but only for its own path). The browser path is explicitly out of scope for this PR and was already order-dependent beforehand, so I am not treating it as a defect here. I am verifying it against a real fixture separately and will report what it actually does. Recommendation: clean.

Triage sweep across all 17 open PRs on this branch queue: this one is fully green. No failing check, no pending check. It is waiting only on the admin merge that agent-authored PRs need (the Nine PRs are in this same state right now: #3922, #3971, #3973, #3979, #4029, #4039, #4041, #4079, #4081. Nothing in them needs work. Flagging because the queue is CI-bound rather than work-bound: draining these unblocks other things. #4079 in particular fixes the revert-oracle's Python blind spot, which is the only reason #4048 is red, and #3971 and #3943 each gate a follow-up issue (#3972 and #3946) that cannot start until they land. |
…3979) * test(parity): compare server/browser IFC type-name sets per concept (#3966) Five defects in two days (#3949, #3948/#3955, #3963, #3964, #3965) were the same shape: the Rust server path and the TS/WASM path independently implement the same extraction and drift apart, unnoticed because each side stays internally self-consistent. Georeferencing already has a dual-implementation parity harness driven by shared fixture vectors (rust/core/tests/georef_parity.rs / packages/parser/src/georef.parity.test.ts); building the equivalent output-comparison harness for relationships/spatial/ properties/quantities/materials would mean inventing a shared fixture format for five different data shapes across two languages. The issue names the cheap version that would have caught three of the five mechanically: comparing the two sides' type-name sets. This adds that version. scripts/check-server-browser-type-parity.mjs reads both sources (the same shape as the existing check-clash-degenerate-reason-parity.mjs and check-legacy-entity-coverage.mjs gates, for the same reason: reading two sources and diffing text is what check-source-text-assertions.mjs bans inside a test file, so it lives here as a lint) and compares, per concept, the set of IFC type names each side switches on. A documented ALLOWLIST (status: 'deliberate' for settled trade-offs like #3254's IfcPhysicalComplexQuantity gap, 'pending' for known divergences with an open PR or an undecided maintainer call) suppresses only the exact type/side it names; any other divergence fails loudly. Both directions are compared symmetrically. A vacuity guard fails the gate rather than silently passing when an extractor returns nothing. Verified against current main: the gate passes given the allowlist; removing a type from either side, for each of the five concepts, turns it red naming the correct side and direction (confirmed then reverted); a fake divergence not on the allowlist still fails; adding a type to both sides stays green. materials passes with zero allowlist entries, matching the sweep's finding that materials extraction already matches. Wired into .github/workflows/test.yml's node-tests job and package.json's check:server-browser-type-parity script, alongside its own regression harness (scripts/check-server-browser-type-parity.test.mjs, 26 cases) proving the gate actually fires in both directions, per concept, and cannot pass vacuously. Does not fix #3963/#3964/#3965 — open PRs #3971/#3969/#3973 do that; this harness's allowlist points at them rather than duplicating the fix. Closes #3966 Claude-Session: https://claude.ai/code/session_01QPHChk3Ve9N519A4kY7436 * fix(parity-gate): detect under-read siblings, correct vacuity-guard claim (#3979 review) Two review findings on the #3966 parity harness (PR #3979): 1. Silent-pass shape: rustRelationshipTypes and tsRelationshipTypes each read exactly ONE bounded region (`let rel_types = [...]`; three named `*_REL_TYPES` Sets). A later patch adding genuinely new types via a sibling binding -- e.g. `let extra_rel_types = [...]` next to the existing array, or a 4th `*_REL_TYPES` Set -- is invisible to these extractors: verified in an isolated repro that the gate stays green while the server genuinely handles a type the allowlist still lists as a gap. Both extractors now throw ExtractorUnderReadError when such a sibling is detected, reported as a distinct failure category ("the extractor may be under-reading; update it") rather than compared as if complete. Scoped by name (REL_TYPES-only) so it does not fire on this file's other, unrelated *_TYPES sets (verified against the real tree). 2. The header's "VACUITY GUARD ... both extractors must return a non-empty set" claim is not true for `properties`: tsPropertyTypes unconditionally seeds IFCPROPERTYSINGLEVALUE (the TS switch's `default` arm has no literal to find), so that side can never be empty and its half of the guard can never fire. Corrected the header to scope the claim rather than touching the seed, which is deliberate and correct. Adds 7 tests (26 -> 33) covering both findings, including a control that disables the new detector and confirms the same silent-pass repro goes green again. Claude-Session: https://claude.ai/code/session_01QPHChk3Ve9N519A4kY7436 * fix(parity-gate): extend the under-read sibling guard to spatialTypes and quantities The #3979 review found that rustRelationshipTypes/tsRelationshipTypes each read exactly ONE bounded region, so a later patch adding real types via a sibling binding (e.g. a 4th `*_REL_TYPES` Set) would be silently invisible to the gate, and hardened those two extractors with assertNoUnrecognizedSiblingBindings. The same bounded-single-region shape existed, unguarded, in two more places: - rustSpatialTypes / tsSpatialTypes: `is_spatial_type` (a single closure) and `SPATIAL_STRUCTURE_TYPE_ENUMS` (a single array) are each the sole region read. Verified with a standalone repro before this fix: adding a sibling `let is_new_kind_spatial_type = |type_name: &str| { matches!(..., "IFCNEWSPATIALKIND") };` next to `is_spatial_type` in a mutated copy of spatial.rs left the gate fully green (`spatialTypes: OK`) even though the server now genuinely recognizes a type the TS side does not - the exact silent-pass shape the relationships guard exists to catch, just not applied here. - tsQuantityTypes: `QUANTITY_TYPE_MAP` is the sole object literal read from columnar-parser-indexes.ts; the Rust side and the `properties`/`materials` extractors already scan their whole source with an unanchored `matchAll` rather than one bounded region, so they do not share this failure mode and are correctly left unguarded (documented in the header now). recognizedNames for spatialTypes intentionally includes the three existing subset lists (BUILDING_LIKE/STOREY_LIKE/SPACE_LIKE_SPATIAL_TYPE_ENUMS) and closures (is_building_like_spatial_type, is_space_like_spatial_type) so the real, unmutated tree keeps passing - only a genuinely new, unrecognized sibling trips it. Adds 4 tests (33 -> 37): RED for a sibling closure/array on each side of spatialTypes, RED for a sibling map on the TS side of quantities, and a control confirming the real tree (master list plus its known subsets) still passes clean. node --test scripts/check-server-browser-type-parity.test.mjs: 37 passed, 0 failed. Confirmed the 3 new assertions fail against the pre-fix extractors (git show HEAD:... diffed back in), pass after. node scripts/check-server-browser-type-parity.mjs, check-module-size.mjs, check-test-wiring.mjs, check-source-text-assertions.mjs: all OK. Claude-Session: https://claude.ai/code/session_01QPHChk3Ve9N519A4kY7436 * fix(scripts): detect stale entries in the type-parity ALLOWLIST An ALLOWLIST entry mutes a divergence for a reason (an open PR, or a settled `deliberate` trade-off), but nothing ever un-mutes it once that divergence is fixed — the entry keeps citing a merged PR or a gap that no longer exists, silently, forever. Add `staleAllowlistEntries()` (scripts/lib/allowlist-staleness.mjs, split out to stay under the module-size budget): for every entry it re-checks the type against the same rust/ts sets the run already extracted and flags it when the type is now on BOTH sides (fixed) or NEITHER side (never a real divergence here). Applies to `pending` AND `deliberate` entries alike — "settled trade-off" describes a decision, not an exemption from reality. Running this against the real tree found four genuinely stale entries: #3969 (extract IfcRelAssignsToGroup(ByFactor)/Nests/ConnectsPathElements server-side) merged since these were written, so relationships:IFCRELNESTS/IFCRELASSIGNSTOGROUP/IFCRELASSIGNSTOGROUPBYFACTOR/ IFCRELCONNECTSPATHELEMENTS no longer describe a divergence and are removed, along with the two existing tests that asserted the old (now-incorrect) behavior. Verified end-to-end by simulating #3971 landing (a stub IFCCOMPLEXPROPERTY arm in properties.rs, reverted before this commit): the checker correctly flags that entry as stale too. 44 tests pass (was 37); the real ALLOWLIST is now 10 pending + 1 deliberate, all confirmed still active divergences. --------- Co-authored-by: Louis Trümpler <78563314+louistrue@users.noreply.github.com>
…fixed The server/browser type-parity gate (#3979) shipped an allowlist naming four divergences as in-flight, two of them by their own text: "open PR #3973" and "open PR #3971". Both merged, so the entries mute nothing and the gate correctly refuses them: [spatialTypes:IFCSPATIALZONE] the type is now handled by BOTH [spatialTypes:IFCMARINEPART] sides -- the divergence this entry [spatialTypes:IFCFACILITYPARTCOMMON] mutes is gone [properties:IFCCOMPLEXPROPERTY] Each PR was green alone; only the merged tree is red, because #3979 added the gate and #3971/#3973 removed the divergences it was told to expect. The gate's own regression tests used two of those entries as fixtures for "an allowlisted divergence does not fail on its own". Repointed at surviving entries rather than deleted, and split across both statuses the allowlist can carry: one `pending`, one `deliberate`. That is strictly more coverage than before, which only exercised `pending`.

#4101) * fix(geometry): split boolean/mod.rs trait wiring back under its ratchet budget #3922 merged from a base 88 commits stale and grew rust/geometry/src/processors/boolean/mod.rs to 948 lines against its recorded budget of 936, turning main red on rust/processing/tests/module_size_ratchet.rs. Every other gate was green; only cargo test observes this one. Move `impl GeometryProcessor for BooleanClippingProcessor` and `impl Default` into a sibling `router_impl.rs`, leaving mod.rs at 921 lines. No allowlist row is added and no budget is raised, per the ratchet's own instruction to shrink or split. Pure move: no geometry logic changes. `chain_cycle_tests.rs` reached the trait through `use super::*`, so it now imports `GeometryProcessor` directly rather than relying on a re-export it never named.

Move `mod router_impl;` up beside the other eight module declarations so the module list reads as one block. No behaviour change.

That makes the previous commit message wrong where it claims "strictly more coverage than before". It was the same coverage, twice, filed under the wrong section headers. Suppression is concept-agnostic (one `ALLOWLIST[`${concept}:${type}`]` lookup), and no spatialTypes or properties entry survives to point a fixture at, so the honest move is deletion plus a note on the surviving test saying where the old fixtures went. Also folds the double blank line the removal left behind.

AGENTS.md "New source files" requires the MPL-2.0 header from LICENSE_HEADER.md on every new file, and LICENSE_HEADER.md spells the three-line comment form for `.rs`. Its siblings in this directory, such as failures.rs, all use exactly that. No CI gate enforces this (add-license-headers.mjs is not wired into any workflow), which is why the earlier pre-flight pass judged the SPDX form acceptable. The written rule is the authority, not the absence of a gate.
