ncc-compliance — AS 1288:2021 gaps (24 total)
| Gap | Description | Count | Severity |
|---|
| Figs 7.1–7.13 | Barrier glass clearance/fixing details — edge fixing positions, fin configurations, handrail geometry | 13 | Normative |
| Figs 5.1–5.2 | Human impact zone diagrams — define which glazing areas require safety glass | 2 | Normative |
| Figs 6.1, 8.1–8.4 | Overhead glazing fall zone (6.1) and installation edge cover details (8.1–8.4) | 5 | Normative |
| Figs 4.27, 9.4 + Table 9.1 | Illustrative examples only — not referenced as required configurations | 3 | Informational |
AS 1288 Supp 1:2006 — no new gaps. "Table 9.1" reference is a cross-ref to parent AS 1288, not a missing Supp 1 artifact. Core numerical tables (glass thickness, Supp 1 lookup tables) fully covered.

Why bronze
Missing entire test-condition table suites from IEC-adopted product safety standards (60335-1, 60598-1, 61558-1). Without test limit tables these standards cannot reliably answer product certification compliance questions.
nz-building-code — 369+ gaps across 27 of 38 standards
| Clause | Description | Tables | Figures | Severity |
|---|
| E2 | External Moisture — primary weathertightness AS, heavily figure-driven. Cladding details, flashings, window reveals, waterproofing. | 48 | 278 | Normative |
| B1 | Structural — loading tables | 12 | 20 | Safety-Critical |
| H1 | Energy — R-values, window U-values by climate zone | 30+ | — | Normative |
| D1 | Access Routes — dimensional requirements | 9 | 30 | Normative |
| G12 | Water Supplies | 11 | 21 | Normative |
plumbing-installation — 133+ gaps across 3 standards
| Standard | Key gaps | Tables | Figures |
|---|
| as-nzs-3500-1-2025 | Water Services — pipe sizing and pressure tables | 15 | 18 |
| as-nzs-3500-2-2025 | Sanitary Plumbing and Drainage — largest gap in skill | 30+ | 30+ |
| as-nzs-3500-4-2025 | Heated Water Services — temperature/pressure requirements | 20 | 17 |
Backflow prevention figures — safety-critical
Figures in the 3500 series include backflow prevention arrangements. Incorrect backflow prevention = contamination risk. These are normative-minimum; a gap here is not permanent-by-design.
AS 1288:2021 has 21 figure gaps across three functional categories. Category D (Figs 4.27, 9.4 and Table 9.1) is purely illustrative — safe to mark permanent-by-design with no decision needed. Categories A, B, and C each contain normative figures that the clause text references as "see Figure X.x" for the required configuration. How far do we extract?
A
Extract all — Categories A, B, and C (16 figures total). Barrier glass clearance diagrams (Figs 7.1–7.13), human impact zones (5.1–5.2), overhead fall zone and installation details (6.1, 8.1–8.4). Path to silver → gold. Staging PNGs available. — most complete
B
Extract Category A only (barrier glass, 13 figures). These have the most ambiguity risk — edge-fixing positions, fin configs, handrail geometry are hard to convey in text alone. Mark B (impact zones) and C (overhead/install) permanent-by-design with a noted gap. Partial gold path.
C
Mark A, B, C all permanent-by-design. Accept silver label for ncc-compliance. The clause text carries the core compliance requirements; figures clarify spatial interpretation but the clause remains queryable. Add gap note in corpus status. — lowest effort
E2 (External Moisture) has 278 figure references — the largest single-standard backlog in the corpus. These are not informational. They are the "acceptable detail" installation drawings: cladding overlaps, back flashings, head/sill flashings, window reveals, roof-to-wall junctions, balcony/deck waterproofing, pipe penetrations. E2/AS1 is the primary weathertightness acceptable solution — a failed weathertightness claim typically traces back to non-compliant installation details, which are what these figures specify. This is the key tradeoff: extraction effort vs corpus accuracy on NZ's most litigation-dense building clause.
A
Extract all E2 figures (~278 images from PDF staging). Achieves full normative accuracy on the most queried NZ clause. Likely 1–2 days of pipeline work. Puts nz-building-code on a clear path to silver (after B1/H1 tables also extracted). — recommended for corpus accuracy
B
Priority subset only: extract cladding installation details (~60–80 figs) and window/door reveals (~40–60 figs). These cover ~50% of the figure count and the highest-frequency query types. Mark the rest (roof junctions, penetrations, balcony) permanent-by-design with noted gaps.
C
Mark all E2 figures permanent-by-design. Accept bronze/silver label for nz-building-code. Add corpus status note: "E2 installation figures not indexed — query E2 clause text for requirements; contact engineer for figure interpretation." Lowest effort.
Three IEC-adopted product safety standards (60335-1, 60598-1, 61558-1) are missing their entire test-condition table suites (~80 tables). These tables contain the pass/fail limits used in product certification — temperature limits, dielectric test voltages, creepage distances, test load conditions. Without them, the electrical skill can answer regulatory/legislative queries reliably but cannot reliably answer product safety certification questions. All three have staging PDFs available. The question is sequencing and priority relative to other Chunk 8+ work.
A
Prioritise for table extraction in Chunk 8+. Extract test-condition tables from 60335-1, 60598-1, 61558-1 in sequence. Then CISPR 15 (EMC), then Wiring Rules (3000). Puts electrical-compliance on a path to silver → gold. Required if the corpus is to support product certification queries. — recommended if certification use case is live
B
Accept bronze label. Scope electrical-compliance for regulatory/legislative queries only (acts, regs, EESS framework, wiring rules). Add corpus status note: "IEC product safety test tables not indexed — skill covers regulatory/legislative requirements only, not product certification pass/fail limits." Defer extraction until a certification use case is active.
- Grant reviews D1–D3 and replies in Teams with choices (use "Copy summary" below).
- jas-anz-accreditation — immediate: run
verify_label.py to write gold label. No decisions needed — this unblocks independently.
- ncc-compliance: based on D1 decision, extract target figures (or mark permanent-by-design) → run
verify_label.py to write updated label.
- nz-building-code: based on D2 decision, plan E2 figure extraction batch. Also queue B1 structural loading tables (safety-critical, no decision needed).
- electrical-compliance: based on D3 decision — either begin test-table extraction sprint or write corpus-status note and move to next skill.
- plumbing-installation: no D-decision needed — pipe sizing, drainage sizing, and heated water tables are all normative. Queue extraction for Chunk 7/8.
Label write policy
No labels are written to registry until Grant approves. verify_label.py is the only authorised label writer. After decisions, each skill gets a fresh verify_label.py run to write the final label — not before.
🧱
ncc-compliance — keep silver or push to gold now?
Silver is a reasonable resting place if the figure gaps are marked permanent-by-design. But if AS 1288 queries are coming, gold is cleaner to communicate to users. Worth a call on urgency.
🌧️
E2 weathertightness — how active is NZ use right now?
If NZ queries are live or imminent, E2 figures matter a lot — these are the "acceptable detail" drawings for AU/NZ's most litigated building clause. If NZ is low-priority for now, Option C is fine.
⚡
Electrical certification — is this a live use case?
D3 is essentially: "do we have product certification users?" If yes, prioritise. If the corpus is used for regulatory/legislative research only, bronze is acceptable for now and the note is honest.

Anything missing from the gap analysis?
The scan was structural (clause-level refs to tables/figures). Any qualitative gaps — standards not ingested, skill areas that feel thin — flag here and they go into Chunk 7 scope.
