Cross-component rules — rule-rail-envelope, rule-tvs-clamp-vs-absmax, rule-u4-inverting-stress, rule-ldo-dropout-chain, rule-ab-interface-current, rule-q1-gate-drive-vs-contract, rule-inverting-startup-vs-pd-source, rule-pptc-vmax-vs-rail, rule-evidence-chain — with the records and facts each spans, its conditioned calculations, and what it refuses to conclude.

A component record answers questions about one part. These rules answer the ones that span several — whether a divider built from two resistors keeps a third part inside its own limit, whether a clamp event stays under everything downstream of it. Each rule is projected whole from stored evidence: its conditions, the exact facts it rests on, any conditioned arithmetic, and the exact wording of what it refuses to conclude.

How to read these rules

  • The refusal is the rule. — Every rule states, in its own words, what may NOT be concluded from the evidence above it. That sentence is the rule's real output; the verdict is shorthand for it.

  • A verdict belongs to the rule, not to a part. — A rule's verdict says how far the cross-component question has been settled. It is never a judgement about any of the parts the rule names, and the verdicts are never combined into one.

  • Calculations are conditioned, and the conditions are the point. — Each calculation publishes its expression, its inputs and the exact results that were recorded, together with the conditions under which the answer means anything. A result read without them is arithmetic mistaken for a measurement.

  • Numbers here were carried, not computed. — The expressions are published so a reader can redo the arithmetic. This page does not evaluate them — the results shown are the ones the evidence recorded.

  • An evidence chain does not flow downhill. — A stage being settled says nothing about any stage after it. A document confirming a limit is not a measurement of the assembled board.

rule-rail-envelope

What this rule asks: Whether every part on the input rail stays inside its own recorded limits across a legal power contract, a mis-contract, and a transient clamp event.

  • Domain: rail-envelope

  • Verdict: NEEDS BENCH

This rule refuses to conclude: Do not declare any rail voltage correct from setpoint arithmetic; no v4 board has ever reached a negotiated 15 V contract, so every intermediate and output rail remains bench-unproven end to end.

Conditions: Trace the full envelope 15 V PD contract -> +13.5/+7.5/-13.5 V DC-DC intermediates -> +12/+5/-12 V LDO outputs, with the +15 V hop crossing the locked A-to-B J4/J5 interface. Every setpoint is nominal-resistor arithmetic at the 1.23 V typical reference; no v4 board ever completed PD negotiation, so no rail in this envelope has ever been energized from a negotiated contract, and load/line/thermal state remains separate per stage.

rule-tvs-clamp-vs-absmax

  • Domain: tvs-clamp-vs-absmax

  • Verdict: UNSOURCED

This rule refuses to conclude: Do not clear the TVS protection chain: the STUSB4500 absolute maxima are mirror-only, no installed clamp or surge waveform has been measured, and a clamp event arithmetically exceeds the Q1 VDS rating. TVS2's decision-a replacement (SMAJ6.5A/C87267) resolves the demoted SD05's zero-margin standoff BLOCKER, but the D5-side findings above remain open and the SMAJ6.5A 11.2 V clamp point cannot be cleared while no downstream +5 V absolute maximum is retained.

Conditions: Compare each TVS clamp/standoff against its downstream absolute maxima: D5 SMAJ20A on VBUS_IN clamps at the 32.4 V table point, 4.4 V above the mirror-only 28 V STUSB4500 VDD/VBUS-pin absolute maxima and 2.4 V past the Q1 -30 V VDS rating when the load switch is off with VBUS_OUT near 0 V, but 12.6 V under the LM2596 45 V input rating; D5's 20 V standoff leaves 5 V of margin at the 15 V contract and zero at a 20 V contract; SMAJ15A holds a 3 V / 25 percent standoff margin on the +/-12 V rails while the TVS3 orientation on -12 V is not yet locked; TVS2 (decision a replacement, Brightking SMAJ6.5A/C87267) holds a 1.5 V / 30 percent standoff margin over the +5 V rail, clears the L7805 5.2 V guaranteed upper output band by 1.3 V with its 7.22 V minimum breakdown 2.02 V above that band top, resolving the demoted SD05's zero-margin BLOCKER standoff fact; its 11.2 V maximum clamp at the 35.7 A 10/1000 us table point has no retained downstream +5 V absolute maximum to compare against (the L7805 bundle retains no output-pin absolute maximum, the coverage gap decision a records), so the TVS2 clamp exposure stays unverifiable rather than PASS. All clamp values are 10/1000 us table points, not the installed surge waveform.

rule-u4-inverting-stress

  • Domain: u4-inverting-stress

  • Verdict: NEEDS BENCH

This rule refuses to conclude: Do not treat the nominal 16.47 V absolute-maximum margin as proof: a VBUS clamp event arithmetically exceeds the U4 effective-input rating, and no ringing, startup, or surge waveform has been measured on the inverting stage.

Conditions: U4's GND pin rides at the -13.5 V output, so the device sees VIN plus the output magnitude: 28.53 V nominal against the 40 V operating and 45 V absolute-maximum input ratings. At the SMAJ20A 32.4 V clamp table point the same chain reaches 45.93 V, 0.93 V past the absolute maximum - a conditioned table-point subtraction, not a waveform claim. C9 bridges +15 V to the -13.5 V rail: 28.5 V of applied stress at nominal, leaving 21.5 V of margin to its 50 V rating. Switching-node ringing, startup overshoot, and any real clamp waveform at U4 are unmeasured.

rule-ldo-dropout-chain

  • Domain: ldo-dropout-chain

  • Verdict: NEEDS BENCH

This rule refuses to conclude: Do not claim any regulated output at rated load: the +12 V dropout at 1.2 A is unspecified, the +5 V margin is typical-only, and the -12 V regulator operates outside its guaranteed input band, so only bench measurement or a design change can close this chain.

Conditions: Evaluate each LDO's input headroom against its dropout evidence at the project load: L7812 has 1.5 V of headroom from +13.5 V, 0.5 V short of even the 2 V typical 1 A dropout, and DS0422 specifies no dropout at the 1.2 A project rating; L7805 clears its typical dropout by 0.5 V at the 5.0 V nominal output but only 0.3 V at the 5.2 V guaranteed upper band with no guaranteed-maximum dropout, leaving zero guaranteed input margin at 7.5 V; CJ7912's -13.5 V input sits 1.0 V outside its -14.5 to -27 V guaranteed operation band, so its 1.1 V typical dropout is the only evidence it can regulate at all. All three depend on unverified upstream DC-DC setpoints.

rule-ab-interface-current

  • Domain: ab-interface-current

  • Verdict: NEEDS BENCH

This rule refuses to conclude: Do not promote the 1.6x derated nameplate margin to an installed-capacity PASS: the harness is unbuilt, the derating factor is assumed rather than measured, and the receptacle carries the same 3 A with zero margin.

Conditions: The locked A-to-B contract carries the full +15 V feed on J4/J5 pins 1-2 with a paired GND return on pins 5-6: two 3 A nameplate XH contacts at 80 percent continuous derating give 4.8 A against the 3.0 A PD-contract cap, a 1.6x derated margin (2.0x nameplate). The same 3.0 A cap is the receptacle's zero-margin mirror rating and flows through Q1 (-4.2 A continuous rating). The mating housing, crimp contacts, and wire gauge are unselected, so no installed harness capacity exists to measure.

rule-q1-gate-drive-vs-contract

  • Domain: q1-gate-drive-vs-contract

  • Verdict: NEEDS BENCH

This rule refuses to conclude: Do not authorize any 20 V-capable PDO or NVM image while the present gate network arithmetically exceeds the Q1 VGS absolute maximum at 20 V, and do not certify 15 V-only operation without a measured gate waveform.

Conditions: With VBEN asserted low, the R11/R12 divider sets VGS = -VBUS x R11/(R11+R12): -9.62 V at the 15 V contract (2.38 V of margin to the +/-12 V absolute maximum) and -12.82 V at a 20 V contract, 0.82 V past the absolute maximum - the deterministic BLOCKER margin fact that feeds the wave-6 20 V-contract decision. Ideal steady divider only: MOSFET capacitance, the real VBEN waveform, and parasitics remain open, and the absolute maximum is not an operating target.

rule-inverting-startup-vs-pd-source

  • Domain: inverting-startup-vs-pd-source

  • Verdict: NEEDS BENCH

This rule refuses to conclude: Do not assume the -13.5 V stage starts on a compliant 3 A PD source: the documented startup demand exceeds the contract by 1.5 A and only bench startup capture on a current-limited source can prove behavior.

Conditions: The manufacturer documents that U4's inverting startup can draw input current up to the ~4.5 A device current limit for 2 ms or more, 1.5 A beyond the 3.0 A PD-contract cap that the source, receptacle, and A-to-B interface share, and warns that current-limited sources may not start correctly. Whether a real adapter folds back, hard-resets the contract, or rides through on input capacitance is source-dependent; the datasheet's own mitigations (delayed startup, enlarged CIN) are not presently designed in.

rule-pptc-vmax-vs-rail

  • Domain: pptc-vmax-vs-rail

  • Verdict: NEEDS BENCH

This rule refuses to conclude: PTC1's decision-g replacement (SMD1210P150TF/16, C7529589) resolves the deterministic Vmax BLOCKER the demoted part carried, but do not treat this rail as bench-cleared: no 85 C hold-current figure is retained for the /16 variant, the family's derating curve estimates the 1.2 A rail budget could be crossed near ~48 C ambient (decisions.json dec-g-ptc1-replacement), and tripped-state behavior at the real fault waveform remains unmeasured for all three PPTCs.

Conditions: A tripped PPTC absorbs its full rail voltage, so Vmax must cover the rail: PTC1 (decision g replacement, RUILON SMD1210P150TF/16 C7529589, demoting the SMD1210P200TF/C20808) rates 16 VDC on the +12 V rail, +4 V of margin; PTC2 (33 V on +5 V, +28 V) and PTC3 (16 V on -12 V, +4 V) also PASS on voltage. Hold-current margins of 0.3/0.6/0.7 A over the 1.2/0.5/0.8 A rail ratings PASS at 25 C but derate toward 85 C -- PTC1's thinner 0.3 A margin (vs the demoted part's 0.8 A) has no retained 85 C hold figure for the /16 variant, and tripped-state behavior at the real fault waveform is unmeasured for all three.

rule-evidence-chain

What this rule asks: How far each claim has travelled from a manufacturer document towards a measurement on real hardware, stage by stage.

  • Domain: source-to-bench-chain

  • Verdict: NEEDS BENCH

This rule refuses to conclude: A completed upstream stage never implies a later as-built, programmed, or measured stage; every downstream stage stays open until the dead v4 boards confirm the diagnosed root cause on the bench.

Conditions: Trace every cross-component claim through official source, conditioned requirement, generated netlist, symbol/footprint, PCB orientation, BOM/CPL identity, as-built inspection, programmed NVM state, and bench evidence. The v4 root-cause diagnosis (CC termination) is netlist-stage evidence only; every stage from PCB orientation through bench is OPEN and the board-split respin is explicitly gated on bench-confirming the root cause on the dead v4 boards.

The stages a claim passes through, in order. A settled stage says nothing about any stage after it: a manufacturer document confirming a limit is not an inspection of the assembled board, and neither is a measurement. A stage with no facts against it is not one nobody got round to filling in: nothing has been established there yet, so the rule's conditions and its refusal above are the whole of what is known about it.

Evidence stage status

Recorded termWhat it means
MIXEDSome claims at this stage are settled and others are not. It is not a completed stage, and the facts listed against it are the ones that carry it.
OPENNothing at this stage has been established yet. A completed earlier stage does not imply it.

Raw agent resource

These rules are generated from a stored evidence bundle and do not restate it. The bundle is the source of truth: where the two ever disagree, the bundle is right and this page is stale.

No owning bundle is identified in the published model, so no reciprocal link can be given.
