/* References: our saffah_codex_6a_agg3 formatter experiment
https://duck.ac/submission/125982, which exceeded compiler memory during
constexpr evaluation; the original engine and table references remain below.
Idea: Encode the trimmed head and length in one 32-bit record: the top nibble
holds length-1. For a four-digit head, that nibble is already 3 in its last
ASCII digit; shorter heads put it in an unused padding byte. Emit the records
as a compact string literal, avoiding large constexpr construction and keeping
the source within the site's code-size limit. Runtime digit output is exact.
Purpose: Reduce head-table size and make the formatter compile economically.

representation idea. No independent license declared.
Idea: For the common 13-to-16-digit answer, table-load the already trimmed
leading four-digit group and its length together. Store that head, then the
three fixed-width four-digit groups at offsets from its length, including the
newline in the final packed store. This removes the separate leading-zero
lookup and cross-word variable shifts; all other output ranges retain their path.
Purpose: Shorten answer formatting's dependent shift chain.

* Day t = P..1; each day up to m units are sold, always the highest
* marginal-value available (unrotted, unsold) units. Vegetable i's first sold
* unit is worth a_i+s_i, every further unit a_i.
* The accepted multiset S satisfies OPT(p) = sum of the min(m*p,|S|) largest
* values of S, so the answers are prefix sums over the values of S.
*
* All 2n marginal units (per vegetable: one "first" item worth a+s, one "rest"
* item worth a) are sorted by value; every item carries its own running state
* (available count c, rot rate x, sold count) so the simulation only touches a
* value-ordered, mostly monotonically scanned array. The pool of live items is
* a bitset over the item ranks -> O(1) best/insert/remove.

reloaded on EVERY answer -- two store-forwarding round trips in the hot path).
In its place one `shrd` + one `shrx` in one asm block.

The caller used to re-derive `cw` from the rank it had just been given:
rk = bfirst_above(cw0 + 1); cw0 = rk >> 6; cw = BS0[cw0];
By construction `cw0` is EXACTLY the word bfirst_above found the bit in -- its
first two probes are w0min and w0min+1 and they return (w0<<6)+ctz(BS0[w0]);
bfaslow likewise returns (w0<<6)+ctz(b) for the b it accepted -- so that second
load fetches the SAME 8 bytes one instruction later. On the loop-carried path
load BS0[..] -> tzcnt -> rk -> rk>>6 -> load BS0[..] -> tzcnt -> rk'
the reload adds a full L1 latency (~5 cycles) for nothing, on every iteration
that takes the `!cw` route (74 % of them). Handing the word back removes the
load from the chain instead of removing instructions from it.
NOTE: the word is NOT always handed back -- bfirst()'s stale-BS2 repair returns
-1 and the callers only read the word when rk >= 0 (bfaslow2's -1 likewise). */

predicate, the `t > 1` load and the `if (ns2 >= tot)` test into dead code
on 99 999 of 100 000 days. No lane has ever built this: EA1's `s_nokeep`
(7.486 ms, LOSS) only re-spelled `keep` lazily and left doclear live --
it removed 2 instructions, this removes ~10 -- so its price is NOT a
price for this construction.
Guard: `nox0` (no vegetable has x == 0) and P >= 2, both checked at parse
time, so any other input takes the ORIGINAL loop unchanged. With keep==1
the code never stored the clear in BS0 anyway and `keep`'s only consumer

x 100 000 days that is 1.5-1.8 M cycles of the row, and it is the one chain in
this loop no earlier lane touched: FB1/EA1/NEX-C attacked `bfirst_above` (the
mid-day successor), the sell body and the cursor recurrence -- this is the
per-DAY recurrence, which is a different object.
The pool is walked in DESCENDING VALUE order every day, so the top rank
PERSISTS: during a day the sell loop only ever inserts ranks >= the cursor (a
rest item's rank is always >= its own first item's rank, which IS the cursor),
so a lower rank can appear only through that day's own insertion loop, which is
tracked here with one compare. The carried rank is re-tested LIVE in BS0 at the
