`awg_metric`AWG / kcmil against IEC 60228 mm², both ways, by area and by maximum resistance at 20 °C (4/0 AWG is not 95 mm²), each size with its resistance and source (NEC Chapter 9 Table 8, UL 1581 Table 30.3, IEC 60228:2023 Table 4, 0.5 to 3500 mm²); with k, the ICEA insulation constant K (MΩ·1000 ft at 15.6 °C) in MΩ·km and why it cannot be checked against an IEC Ki. Send awg or mm2 (one of them), metal Cu (default) or Al. Use it to translate a North American size; to decode a whole designation use decode_cable_code, to size a cable design_cable. An unknown size is a 400 that names the sizes. Free, deterministic, no LLM.

`degassing_time`The Pro degassing estimate (research/degassing/PLAN.md): how many days an XLPE core stays in the oven until a share of its crosslinking by-product is left, by Fick diffusion with published coefficients (Polymers 11 (2019) 1439; the methane D0 and Ea of IEEE PES T&D 2016 as quoted there; Electric Wire & Cable 2025 at 65 C), never a standard's result: no standard gives a degassing formula, time or residual limit.

`extract_datasheet`Read a power cable datasheet (a maker PDF, an https link to one, or pasted datasheet or tender text) into constructions: every cable size it states with voltage, cores, conductor, each layer with its nominal and smallest thickness, screen and armour data, diameters and the claimed standards, each with the page and the row it was read from, the values that could not be read and the ones the reader is unsure of. The reading is done by an LLM (Claude) and shown as read; it decides nothing. Each construction is ready for check_cable / POST /api/v1/check, and with standard set every row is checked by the deterministic rule engine in the same call, each rule with its clause and source. Review the values before relying on a verdict.

`find_equivalents`Find the equivalents of a power cable in other countries' standards ("the Dutch equivalent of this Swedish cable"): the decoded cable is rebuilt under each target rule set (IEC 60502, HD 603, HD 620 sections J/M/D/C/K, BS 5467/6724/7846/6622, EN 50618, HD 627) with the same conductor, section, cores, voltage, screen, armour and sheath, then compared layer by layer with the source of every value.

`read_tender`Read a project or tender document (a purchase or project specification, a tender volume, a GTP / data schedule; a PDF of up to 80 pages and 20 MB, or its text) and answer what it asks for: every cable it lists built as a design by the designer's rules and checked against its rule set, the required / offered schedule beside the document's own required values with their pages, each requirement mapped to a requirement card or listed as having none, the conflicts (one parameter with two values, a printed construction against a requirement, a value against the standard the document names, a voltage outside IEC 60038, a schedule row with no construction) and the missing sections. An LLM (Claude) copies the document's values and pages; it decides nothing: every design, check, conflict and gap is the deterministic rules with their sources.
