A clean review window only proves an interface was silent for that window.
For a heavily used interface that is weak evidence -- an infrequent caller
can fall outside the window entirely, so the interface reads as retirable
while still having consumers.
_retirement_state now also requires silence since last_seen_at, scaled by
all-time volume (RETIREMENT_QUIET_LADDER): 7d under 100 calls, 30d under
10k, 60d above. Existing guards (retired / manual hold / replacement ref /
replacement verified / in-window traffic) still take precedence.
On the 2026-08-20 capture this makes 15 of 19 legacy interfaces retirable
and holds 4: the three six-figure /workstreams/ read paths, and
GET /tasks/?workstream_id which still has live traffic.
Unblocks the bulk of Wave E2 in the cutover slice plan. 7 new tests.

capture_legacy_meter_evidence.py fell back to hours=8 whenever --days was
omitted, and --hours itself defaulted to 8. Every unattended capture sampled
06:00Z-14:00Z while writing a file named weekly-review with cadence: weekly.
39 of 40 captures ran this way; only 2026-07-08 used a true 7-day window.
Calls outside the band were never sampled, so interfaces with live callers
reported as retirement candidates -- GET /tasks/?workstream_id was flagged on
2026-08-19 despite traffic on 2026-08-18.
Default the script to days=7; keep --hours for spot checks, documented as not
retirement evidence. Adds corrected capture for 2026-08-20 and records the
residual gap (candidate rule ignores last_seen_at) against STATE-WP-0079-T05.

Assign all 425 SHR-INV-0001 items to 19 slices across five waves plus Keep,
each with adapter flag, owner API, and rollback. Coverage computed against
the inventory rather than hand-counted.
Only Wave A (repo-manager, 165 items) is executable; B/D1/D2 are gated on
owner-side contracts still at proposed. Flags two findings for T04/T05: the
9 ops_dependency items cannot be strangled behind a flag, and the
legacy-meter weekly review window is 8h, not a week.
Also corrects the workplan status from proposed to active.
