Scanner 404 Block W - structural scanner families

Elazar directive 2026-09-22: every scanner sweep that lands a new shape pages a human and an agent. Block W adds four structural families to the scanner-probe down-tier, byte-identical in mars/pluto/venus: W-a any dot-leading path segment except .well-known (retires the .git*/.hg/.bzr hold-outs), W-b backup/swap suffixes (~ .old .orig .save .swp .bak1...), W-c non-Next server/config/key/dump extensions (.aspx .jsp .config .sqlite .pem .pub .lock ...), W-d exact-segment infra/debug endpoints (server-status, _ignition, swagger, jenkins...). Collision-proven 0 hits vs every page/route template + public/ file in mars 88, pluto 95, venus 84, terra 31. Trigger: /.codex/auth.json~|.old|.save sweep 2026-09-22 08:59Z.
