docs: mark MX-exclusion plan Fix 1 + Fix 3 shipped

Browse source 
Fix 1 (consumer mx: exclusion) and Fix 3 (pw-mx-tag cron) live as of 9eeed47.
Verified: warmup pool 353,909 after fix (not starved), mx:yahoodns.net cap=0
during warmup, cron tags idempotently. Fix 2 (NULL bucket cap) deferred.

# Plan: close the MX-exclusion gaps in the trucking warmup
**Status:** PROPOSED (2026-06-20). Analysis + design only; no code shipped yet.
**Status:** Fix 1 + Fix 3 SHIPPED 2026-06-20 (commit `9eeed47`); Fix 2 deferred.
**Owner context:** warmup day 17; big operators (Google/Microsoft/Proofpoint/
Mimecast/Barracuda/Cisco/Broadcom) are EXCLUDED until day 30, then re-introduced
via `mx_daily_caps()`. This plan fixes three holes that let throttling/consumer
MX operators through during that window.
## What shipped (2026-06-20, commit `9eeed47`)
- **Fix 1 (DONE):** `CONSUMER_MX_OPERATORS` (mx:yahoodns.net, mx:icloud.com,
comcast/charter/centurylink/windstream/tds/earthlink) folded into
`WARMUP_EXCLUDE_OPERATORS`, used by both the `fetch_carriers()` exclusion SQL
and `mx_daily_caps()` (same day-30 ramp). Verified live: warmup-eligible pool
= 353,909 carriers after the fix (not starved), and `mx_daily_caps()` returns
cap 0 for mx:yahoodns.net during warmup.
- **Fix 3 (DONE):** `infra/cron/pw-mx-tag` installed to `/etc/cron.d/` (05:45 UTC
daily, `--only-unsent --limit-domains 20000`). Verified: a 200-domain test run
tagged 216 domains; idempotent/bounded.
- **Fix 2 (DEFERRED):** bounding the NULL bucket cap — the cron will drain the
backlog, revisit if NULL stays large.
