-- sql/144-fix-false-curated-10g-compat.sql
-- Manual, datasheet-verified correction of 14 CURATED (verification_method=
-- 'vendor_compat') compatibility rows that claim 10G transceivers are
-- compatible with switches whose ports are physically 1G-only.
--
-- The automated guards (126/138/141) deliberately never touch curated rows --
-- on understated switches, curated data is normally the source of truth that
-- RAISES the ceiling. These 14 rows are the documented exception: verified
-- 2026-07-18 against Cisco's own primary documentation:
--   * Cisco ASR 9000 Transceiver Module Support Matrix (C78-624747-06):
--     A9K-40GE-L/B/E -- SFP=Yes, XFP=No, SFP+=No, QSFP=No, CFP=No. Supported
--     SFP lists are exclusively 100M/1G-class (1000BASE SFP, CWDM "Gigabit
--     Ethernet and 1G/2G FC", DWDM 1000BASE). No 10G module type accepted.
--     A9K-40GE-TR is the packet-transport variant of the same 40-Port GE
--     family (SFP cages only).
--   * Cisco Catalyst 9300 Series Data Sheet (nb-06-cat9300-ser-...):
--     "C9300-48S 48 ports 1G SFP Modular uplinks", "C9300-24S 24 ports 1G SFP
--     Modular uplinks" -- fixed downlinks are 1G; 10G exists only on the
--     separate, optional uplink network module, which TIP tracks as its own
--     switch entity (e.g. C9300-NM-8X).
--   * C9400-LC-48S / C9400-LC-24S / C9600-LC-48S: "48-port 1G SFP line card"
--     per Cisco 9400/9600 line-card documentation (C9600-LC-48S slot
--     bandwidth 96 Gbps full-duplex = 48x1G).
--
-- Likely origin of the bad rows: flexoptix-compat.ts (vendor_compat method)
-- matching 10G Flexoptix parts (P.1696.23.yy, X.1696.23.yy, P.1596.40:Sx,
-- P.Czz.z) to these switch records via the configurator supported-vendors
-- family match -- same scraper lane that produced the sql/125 spec_match
-- cleanup, this time in the curated tier.
--
-- Effect: v_switch_understated_ports drops to 0 (its rows were exactly these
-- curated-faster-than-ports claims), removing the last "understated ports"
-- alert class for these switches. Idempotent.
