CB-WP-0013-T02/T03: retire SH-3 as a gate; correct AM-4a and its target

Browse source 
ADR-0008, tier M (survey and ADR merged).

D1 — SH-3 retired as a gate, kept as a diagnostic. Investigating it
found a third defect, deeper than the two this pass was declared on.
Re-deriving batching from the raw transcripts, independently of cb-cost:

  CB-WP-0011 pass      54 with tools    0 batched    0.0%
    gap -> next decl   16 with tools    6 batched   37.5%
  CB-WP-0012 pass      86 with tools    0 batched    0.0%
    gap -> next decl   10 with tools    1 batched   10.0%
  CB-WP-0013 so far    10 with tools    0 batched    0.0%

Zero batched turns in 150 in-pass responses; 37.5% in one gap, above the
20% floor. Batching needs two calls whose inputs are known at once —
orientation work. Implementation consumes each step's result before the
next. SH-3's window is since the last commit, which during a pass is
always implementation. The metric could not read above ~0% in the window
it was gated on. A floor the window structurally excludes is not a
target.

This pass's own declaration was also wrong: it claimed batching "has got
worse" (7.8-8.6% vs 1.1-6.3%). Differently-placed windows, not different
behaviour. Withdrawn — the same class of error, in the pass written to
correct it.

Not retargeting to match the measurement: the floor was not moved to 6%,
the gate was removed on an argument about what the quantity is worth.
The number is still reported; only the verdict is gone.

D2/D3 — AM-4a counts --edges normal,no-proc-macro: 157,202, not 246,250.
The target moves down with it, 250,000 -> 161,000, so the correction
hands back essentially nothing (headroom 3,750 -> 3,798). Three controls:
the exclusion drops exactly the five expected crates, only removes and
never adds, and is not a no-op.

The DFD gate then caught the follow-on it exists for — three historical
documents carrying live fact tags for a number that had changed. Not
rewritten; untagged, with a supersession banner.

AM-4b is deliberately not corrected: its proc-macro share is unmeasured.

gate-review now reads 0 due, 0 silent, 0 drifted — GATE-REVIEW earns its
first caught entry by forcing SH-3's re-justification, and the registry
has no silent gates left.
