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.

Complete retirement of suggestions, workstream aliases, and other `retire`
inventory items once meters/callers allow. Keep historical rows archive-readable.
**Blocker identified (2026-08-20):** the legacy-meter evidence this task gates
on was being captured over an 8-hour band, not a week —
`capture_legacy_meter_evidence.py` fell back to `hours=8` whenever `--days` was
omitted, so 39 of 40 captures sampled only 06:00Z–14:00Z. Interfaces called
outside that band read as unused. Three candidates on the 2026-08-19 capture had
live callers, including `GET /tasks/?workstream_id` (seen 2026-08-18).
Script default corrected to `days=7`; corrected capture
`docs/evidence/legacy-meter-weekly-review-20260820.json`.
**Remaining work for this task:** the candidate rule in
`api/services/legacy_meter.py` keys only on in-window calls and ignores
`last_seen_at`, so `GET /workstreams/` (144 086 all-time calls, quiet 9 days)
still reports as a candidate. Require a minimum quiet period scaled to call
volume before retiring. See `docs/retirement-cutover-slice-plan.md` § E2.
