+The 0.1.2 candidate strengthens height-evidence boundaries and keeps every geometry inspection within the explicitly requested project, level, and room. Local package and strict Claude marketplace validation pass. Candidate commit `cf729f1decbf9fda5c6e6bb9cd82e06156af9ea3` then passed one prospectively frozen 20-case native Claude gate through the managed CLI connector: 20/20 native tasks, deterministic assertions, host checks, semantic evidence checks, and graph/export nonmutation checks passed with no retries. Whole-response review of the purchase, delivery, and export-boundary cases also passed. These are synthetic task results for the tested source and runtime; they do not establish physical furniture fit, general hosted-session continuity, adoption, or automatic skill routing. The `native-host-validation: source-hash-recorded-separately` metadata points to versioned evidence rather than promising a blanket pass.

+The earlier results remain immutable. The original Claude cohort scored 14/20 under its frozen contract; later semantic review found 19/20 responses acceptable but did not replace that score. The first 0.1.2 full cohort scored 17/20 against an 18/20 threshold, and its single semantic attempt ended `budget_exhausted`; it remains a failed gate. Offline grader calibration was recorded as posthoc evidence only. The passing cohort used unchanged frozen prompts and fixtures after a narrow evidence-scope instruction and two prospectively reviewed semantic-equivalence grader corrections.
+
+A separate tool-free Claude Fable 5.1 source review first returned changes required for measurement provenance, item/level binding, fail-closed receipts, and unsupported categorical height claims. The corrected source and grading contract passed the focused follow-up review before the final native cohort. This source review is not a substitute for the native task gate.

 Manifest hashes are not Git commits or persisted scene identities. Native furniture fixtures used local SQLite storage and direct stdio MCP. The CLI's `mcp connect` command forwards to its managed HTTP service, a distinct transport path tested separately below. The npm `beta` tags still resolve to CLI `1.0.0-beta.1` and MCP `1.0.0-beta.6`; those older registry releases do not establish the candidate-enabled behavior documented here.

 ## Scope and remaining checks
 
+- Bundle 0.1.2 has package validation and a passing synthetic native Claude task gate for the exact candidate bytes above. The earlier 0.1.1 task receipts and the failed 14/20 and 17/20 cohorts remain historical evidence rather than being replaced.
+- D02 automatic-routing evaluation remains pending. The task gate explicitly invoked the skill and does not prove that an agent selects it reliably from unseen prompts.
+- Five clean installations of the final merged 0.1.2 bundle remain pending. Earlier installation checks covered bundle 0.1.1 and do not transfer to the changed skill bytes.
 - The foundation task proves one hosted-development journey, not all general construction, account claiming, or human handoff workflows.
 - Use one active agent client per local CLI service. The standalone HTTP bridge shares scene state across clients; concurrent independent client isolation is not supported. Hosted Community MCP uses a different session-isolated bridge.
 - Cursor Agent can list the configured MCP tools, but is signed out in the validation environment. A native Cursor task is not counted as passed.

 Before calling tools, record the user's constraints: item width, height, depth, original unit and meter conversion, target level/zone, position, rotations, and required clearance.

+Treat numeric `level.height`, `zone.ceilingHeight`, wall height, asset labels, and imported metadata as nominal unless their provenance records a measurement of the clear floor-to-obstacle height over the exact proposed footprint. A categorical height pass or failure requires either that user-supplied measurement or modeled ceiling, soffit, sill, railing, or obstacle geometry whose recorded measurement provenance and spatial extent cover the tested pose. Merely having a ceiling-shaped node, a template default, or a numeric metadata field is not measured evidence. A nominal value can identify a possible mismatch worth measuring, but it cannot by itself support a categorical height pass or failure.

+| Check | Status | Evidence |
+| --- | --- | --- |
+| Room footprint | passed | The tested plan footprint lies inside the measured room boundary. |
+| Height/overhead | insufficient evidence | The 2.70 m values are nominal metadata without measurement provenance, and no ceiling or obstacle geometry establishes the actual clearance above this footprint. |
+| Door access keep-out | not checked | No modeled doors include the prospective candidate. |
+| Delivery route | not checked | Route, opening, packaging, and turning measurements were not supplied. |

+The 3.10 m wardrobe may conflict with the nominal 2.70 m values, so measure the clear floor-to-obstacle height at the intended position. Do not report height as passed or failed until that user-supplied measurement, or modeled geometry with recorded measurement provenance covering the exact overhead path, is available.
