Accuracy pass 4: fix 81 audit findings; retire the Changelog page Implements the independent 2026-07-10 full-content audit of every content page: 81 findings, 0 Critical / 5 High / 26 Medium / 50 Low, applied in the report's remediation order. The Changelog page is retired (below), so this message is the finding-level record of the pass. `make check` passes: source hygiene; cross-references and manifest coverage (228 sections, 71 tables); brand index (44 rows).

Fix 27 findings from the third accuracy review Major (factually wrong): - DiamondBack nozzles attributed to US Synthetic, not E3D, and described as PCD-tip rather than hardened steel (all five mentions, Parts I/III/IV/VI) - PE environmental-stress-cracking claim inverted: ESC is the classic PE failure mode; PP is the less ESC-prone polyolefin - PA66 nozzle split out to 280-300 C (260-280 was PA6-only, near-zero superheat over PA66's 255-265 C Tm) - HTN+CF un-grouped from "far above the prosumer envelope" (3DXTech's window sits inside Table 14.7); qualifier now FibreX-only - Nonexistent "PolyMax TPU95" replaced with PolyFlex TPU95-HF (Table 16.5 and Appendix C) - PVA dissolution bath split by model Tg: 25-35 C for PLA, 40-60 C only for PETG/ABS-on-BVOH - Polyolefin bonding now cites Loctite Plastics Bonding System (SF 770 primer + CA) and DP8010, not Plastic Bonder - PC/PTFE repositioned as the stiffness/heat step-up (PEEK for heat + chemistry) in Table 22.2 - PEBA 40D HDT corrected to ~45-55 C (80-95 belongs to 63D-72D grades); continuous service marked grade-dependent - PA6-CF density harmonized to 1.15-1.23 (~1.20 at 20% CF) Minor: PVB no longer classed as a biodegradable (Ch 21 retitled "Niche polymers"; ToC anchor updated); wood-filled PLA needs bore, not hardness; PC-blend tensile envelope matches its own tables (~40-65 MPa); FR-PC row sourced from Table 15.4 (HDT 86-113, tensile n/p); block-copolymer claim scoped to TPU/TPEE/PEBA; Bambu PPA-CF modulus ~1.3x PPA-CF average (2x vs PA6-CF class); PVDF HF onset attribution reconciled (316 C stability ceiling, ~350 C SDS decomposition, rapid by ~400 C); PPS ~120 C crystallization chamber correctly placed beyond Tier 3/entry Tier 4; POM bed surface "POM-coated sheet"; unsupported CryoGrip note dropped from PA6/PA66; PVDF removed from the 50-100 price tier; paint-vs-bonding primers untangled in 26.3; Porthcurno pointers fixed; Appendix C chapter pointers corrected for Kexcelled, BCN3D, Spectrum, FormFutura, Polymaker; Zytel/Delrin ownership updated (Celanese / Jordan Co).

Source hygiene: remove all 20,945 U+00AD soft hyphens, normalize heading spacing Mechanical cleanup per the publish-readiness review (P1/P3): - Strip every soft hyphen from the 14 content pages (verified byte-level: each file is exactly its previous content minus U+00AD). Fixes source search, browser find, copy/paste, screen-reader output, and diffs. - Insert a blank line before the 34 headings that directly followed a non-blank line, for renderer portability and lintability. - Add check-source-hygiene.sh so both regressions fail fast.

Fix 53 accuracy-review findings across all nine parts Corrections verified against vendor TDS and primary sources: High severity: - Fiberlogy PCTG prints 250-270 C, not 230-260; PCTG moved from Tier 1 to Tier 2 (Table 4.1, Table 8.6, Appendix A.3) - Siraya annealing guidance was inverted: unfilled Fibreheart PPA is marketed as annealable (80-100 C, 4-8 h) (Part I 3.6, Part VI 14.9) - FibreX PPA+GF15 flagged as Tier-4 industrial (365-390 C nozzle), exempt from the Table 14.7 prosumer window - Ultrafuse PC/ABS FR rail cert corrected to EN 45545-2:2016 R26 (EL10) HL1-HL3; HDT 86 C - iglidur i151, not I150, is the FDA food-contact grade - DCM guidance now carries the 2024 EPA TSCA consumer-use ban (89 FR 39254) and precise OSHA/IARC framing Medium/low: removed nonexistent SKUs (Siraya NylonPro/Mecha/Mushroom, Forward AM PEBA, Fillamentum/Spectrum PMMA, ECO-PC FR); fixed misattributions (NylonX, CarbonX/ThermaX/3DXLABS naming, Arnitel to Envalior); corrected figures (HTN+CF 106 MPa, PEI RTI ~170 C, PEI HDT 153-190 C, POM HDT@0.45 155-175 C, PolyMax PC 53.4 MPa and 90 C stress-relief anneal, ESD-PC >10^6-10^9 ohm/sq); Table 14.1 moisture column moved to saturation basis; PP-CF and PPS-CF process settings made brand-split per vendor TDS; added Fillamentum Flexfill PEBA 90A; harmonized PC-blend Tg to 109-145 C and chamber capability in B.1; propagated all fixes to Appendix A/C mirrors and cross-references.

Correct twelve factual errors across the reference Safety: PTFE hot-zone threshold lowered from 280 °C to ~250 °C (aligns with the wiki's own §15.7 liner caution and PTFE's ~260 °C continuous service limit). Values: Fillamentum PMMA Tg 80→~105 °C (HDT 94 > Tg was impossible; family range and Table A.1 updated to 100–110); PEBA 40D Tm ~200→~160 °C (Pebax 4033 TDS). Mechanisms: PP smears under power sanding (claim was inverted); filled PC absorbs slightly less at saturation, not more; POM stiffness comes from crystallinity, not sub-ambient Tg; PPS tooling wear is corrosive (sulfur species), not backbone abrasion; LW-PLA brass rationale replaced. Attribution: Porthcurno (recycled PA6) removed from the Recycled PP row (Braskem FL900PP-CF substituted); 3D-Fuel removed as POM vendor; PolyTerra (carbon-offset, not recycled-content) removed from the recycled-content list; 'all CHDM-containing' softened to 'glycol-modified' (t-glase is PETT).
