Signpost (not a knowledge pack) for the railway RAMS and signalling assurance standards: EN 50126-1:2017 and EN 50126-2:2017 (both with A1:2024) for the RAMS process, EN 50128:2011 (A1:2020, A2:2020) for software for railway control and protection systems, and EN 50129:2018 and EN 50129:2026 for safety-related electronic systems for signalling, plus the free CSM regulations and ORR guidance that cover the risk-process need.

Signpost (not a knowledge pack) for the ECSS European space standards: the E-ST-10 system engineering family, the discipline standards a reader commonly mis-cites (radiation is E-ST-10-12, not a RAM standard; software is E-ST-40, not E-ST-70), the M-branch project management standards, the Q-branch product assurance standards, and the sustainability and system documents, with designation, edition, owner, status, and catalogue URL only. Contains no source content. Free process paths are existing NASA packs in this catalogue, named by slug, and are not ECSS clause substitutes. Several needs have no in-repo pack.

Signpost (not a knowledge pack) for the avionics development assurance standards landscape: RTCA DO-178C / EUROCAE ED-12C and its supplements (DO-330/ED-215, DO-331/ED-218, DO-332/ED-217, DO-333/ED-216); RTCA DO-254 / EUROCAE ED-80; SAE ARP4754B and ARP4761A; and the free regulator documents that recognise them (FAA AC 20-115D, AC 20-152A, Order 8110.49A; EASA AMC 20-115D and AMC 20-152A). Contains no source content: each row carries only the designation, title, edition, owner, redistributability status, and the owner's URL. Use when you need to identify, cite, or locate an avionics standard; paywalled rows point to the owner, free rows point to the regulator text, and the FAA rows also name the in-repo faa-8110-49 pack.

Signpost (not a knowledge pack) for maritime safety and class rules: SOLAS Consolidated Edition 2024 (IH110E) as the paywalled statutory core, ISM Code & Guidelines 2018 (ID117E), ISPS Code 2003 (K116E) and the 2021 guide (IB116E), and COLREGS 2026 (IC904E), with designation, edition, owner, status, and official URL only. Contains no source content. Free-path layers are US flag implementation (eCFR Title 46 and USCG circulars), the USCG Navigation Rules PDF, UK MCA notices under Open Government Licence v3.0, and class portals (DNV, ABS, Bureau Veritas). None of those layers is the IMO consolidated text. No in-repo pack covers these instruments.

Use when the user starts a non-trivial coding/building task in Claude Code (e.g. "帮我做个 X", "help me build Y", "add feature Z", "搭一个 Z"). Layers an AI-native pedagogical coat over normal coding work — surfaces implicit assumptions in user intent, annotates non-trivial design decisions inline with brief concept-scaffolding for terms the user may not know, and replaces "should I run it?" handoffs with rigorous AI self-verification plus a clean list of what only the user can verify. Skip for pure Q&A, single-line edits, read-only investigation, or refactoring along an existing pattern.
