Audit exact electronic-component identities and run the end-to-end workflow for adding or replacing a BOM part. Use whenever circuit, schematic, PCB, BOM, firmware, bring-up, substitution, or related documentation could depend on a component rating, pin, package, source, preview, publication, or interaction.
Resolve exact EXAMPLE-MPN component limits and application constraints. Use whenever EXAMPLE-MPN, its LCSC ID, manufacturer, function, pins, package, substitution, bring-up, or firmware behavior is relevant.
Navigation design rules for the zudo-led-lamp doc site (zudo-doc). Consult before creating new pages, restructuring directories, or changing header navigation. Covers: 3-level hierarchy (header → sidebar → nested), file-structure-is-navigation principle, header nav conciseness, category index pages, sidebar_position discipline, the generated claude* categories, and common mistakes. Triggered by 'nav design', 'navigation structure', 'zudo-doc-navigation-design', 'structure nav', 'add category', 'add header nav', 'add a doc page'.

Run the central offline validator, then read all seven local JSON artifacts. Resolve the controller and both DNP subordinates independently. Cite source and fact IDs with their conditions and locators.
Exact DS12499 Rev 8 and UM2650 Rev 3 bytes are reproducibly retained as MANUFACTURER_MIRROR. Their dependent controller claims remain UNSOURCED under the primary-only trust policy; programmed and as-built state remain open. The UNI-ROYAL external-Rd family specification and Nexperia protector specification are independently available, but they do not close controller behavior. A direct manufacturer-primary retrieval attempt from st.com was made on 2026-08-02 (canonical DS12499/UM2650 resource paths, the STUSB4500 product page, a legacy UM2650 URL, and a community.st.com mirror link): every st.com path timed out and the community.st.com link redirected to its forum homepage instead of the file, so both sources stay MANUFACTURER_MIRROR/SOURCE UNAVAILABLE at primary and every dependent verdict stays UNSOURCED. Do not re-attempt from memory or treat this dated failure as permanent; a future session may retry the same URLs.
Pin 23 (VREG_2V7) is documented decoupling-only, but Board P's generator loads it with R15/R16 4.7k I2C pull-ups and exposes it on debug pogo pad J3.3 (net U1.23 C30.2 R15.2 R16.2 J3.3, fact fact-stusb-vreg2v7-load). This is an explicit open coverage item (cov-stusb-vreg2v7-load) requiring a manufacturer-primary locator authorizing external DC loading of this pin, or a re-route decision, plus confirmation that the NVM-programming jig's logic levels match 2.7 V; it must close before any NVM-programming bench work begins.
For controller work, separate unpowered/dead-battery, reset, configuration-load, normal attached, explicit-contract, fault/recovery, and disconnect states. Treat open-drain as asserted and Hi-Z as deasserted. Do not infer the programmed NVM image: require a normalized 40-byte artifact, byte-for-byte readback, reset reload, full power-cycle reload, and negotiated-output bench evidence. Record the as-received factory image before any write. Check the current ST endurance limit before authorizing repeated writes; the retained record deliberately leaves endurance open.
0Provision only with a current-limited source that satisfies the documented VDD or VSYS operating range and with a common-ground I2C programmer using the board pogo interface. Keep the load disconnected for first power and verify VBUS, gate polarity, discharge timing, CC state, and fault registers in stages. Volatile register edits are not persistent NVM proof.
Apply the netlist assertions in interactions.json exactly. A deterministic wrong pin, missing series discharge resistor, wrong PMOS polarity, or unsafe voltage is a blocker; state-dependent negotiation, timing, thermal behavior, ESD performance, and as-built NVM contents require bench evidence.
Human projection of this bundle: rec-stusb4500qtr, rec-pesd24vs1ub, rec-rd-0603waf5101t5e. Those pages are generated from the JSON files here and add nothing to them — where the two disagree, this bundle is correct. See also the component catalog and the cross-component rules.
