CB-EV-0013: correct the cost table, and the self-quoting rule with it
Some checks failed
ci / check (push) Failing after 3s

The rule adopted in CB-EV-0012 -- quote the previous pass's final cost,
never your own -- was applied here for the first time and did not hold.
This file opened quoting CB-WP-0014 at $7.47/34, which is what
make status reported then; by the close it read $8.56/48. A pass's
window runs to the next pass's first commit, so the previous pass is
not final until the pass after it starts. The rule fixed the wrong
boundary. Recorded as owed rather than changed silently.

Also: CB-EV-0009's prediction now has a point on each side. CB-WP-0014
opened above the SH-1 hard line at 0.220 $/response; CB-WP-0015 opened
below it, after a compaction, at 0.111. Both on the predicted side, and
the second is the control the last report said was missing -- but n=2,
different tiers and subjects, and the compaction that supplied the
control is also what makes the passes differ.

**CB-EV-0009's standing prediction came due and is consistent — once.** It
predicted that a pass opening above the SH-1 hard line would cost more than
0.123 $/response. CB-WP-0014 opened above the line and cost **0.220**.
### The self-quoting rule is not enough, and this pass is the proof
That is one point past a threshold, and it is worth being explicit about
what it is not: there is **no control**. No pass has opened *below* the
line since the prediction was made, the two passes either side differ in
tier, kind and subject, and 0.220 is inside the range product passes have
shown anyway. The prediction is unfalsified, not confirmed. It needs a
pass that opens below the line to mean anything.
CB-EV-0012 adopted the rule that an evidence file quotes the **previous**
pass's final cost and never its own, because four passes running had
under-reported themselves mid-flight. This file opened by quoting
CB-WP-0014 at **$7.47 / 34 responses**, which is what `make status` said
at the time. By the time this pass closed, the same tool reported
CB-WP-0014 at **$8.56 / 48** — the figure moved by 15% *after* it was
supposed to be final.
The cause is mechanical: a pass's window runs to the next pass's first
commit, so CB-WP-0014's window was still open until CB-WP-0015 declared.
**"The previous pass's final cost" is not final until the pass after it
starts** — the rule fixed the wrong boundary. Quoting from two passes back
would be safe; that is a change to the rule, and it is recorded here as
owed rather than made silently.
### CB-EV-0009's prediction now has a point on each side
It predicted a pass opening above the SH-1 hard line would cost more than
**0.123 $/response**. For three passes it was untestable because every one
opened below the line.
| pass | SH-1 at open | $/response |
|---|---|---|
| CB-WP-0014 | above the 300,000 hard line (347,720) | **0.220** |
| CB-WP-0015 | below it (237,533, after a compaction) | **0.111** |
Both fall on the predicted side, and the second is the **control the last
report said was missing**. That is a real strengthening — but it is n=2,
the two passes differ in tier, kind and subject, and the compaction that
supplied the control is also the thing that makes the passes different.
Consistent with the prediction; not yet a demonstration of it.
**Meta budget: 26% `[OVER]`** the soft 25%, on CB-WP-0013's $8.26 sitting
in a trailing three with two product passes. No product work was displaced
