Heimdall's parity ruling (2026-11-08), Python side; Rust is #43 (4828c416), TS is #44. Differs from TS: the python RUDP server dropped a frame that is no msgpack map silently, so this also adds the answer (message_invalid, details.field = "message", fixed reason) and keeps the session. Then the shared cap, MAX_CONSECUTIVE_REFUSED_FRAMES = 8 (module constant in cultmesh_py.server): the 8th consecutive unreadable frame, or 8th consecutive delete the write authority refuses (a response carrying write_not_authorized), is answered with the goodbye and ends that peer's session. A decoded map resets the unreadable run; any delete that is not refused, or any non-delete, resets the delete run.

Touches the write-authority path (refused deletes are counted from the authority's refusal response); the authority's decision and refusals are unchanged. Left unmerged for Heimdall.

Tests: two new (7 answered, reset, 7 more, 8th answered then ended; same for deletes with a granted delete and a snapshot as resets). Six hand mutants fail them under prlimit as=4GiB cpu=300 (cap 7, cap 9, unreadable never resets, delete run never resets, delete never counts, cap removed). cultmesh-py suite passes.

Heimdall's parity ruling (2026-11-08), Python side; Rust is #43 (4828c416), TS is #44. Differs from TS: the python RUDP server dropped a frame that is no msgpack map **silently**, so this also adds the answer (`message_invalid`, `details.field = "message"`, fixed reason) and keeps the session. Then the shared cap, `MAX_CONSECUTIVE_REFUSED_FRAMES = 8` (module constant in `cultmesh_py.server`): the 8th consecutive unreadable frame, or 8th consecutive delete the write authority refuses (a response carrying `write_not_authorized`), is answered with the goodbye and ends that peer's session. A decoded map resets the unreadable run; any delete that is not refused, or any non-delete, resets the delete run. **Touches the write-authority path** (refused deletes are counted from the authority's refusal response); the authority's decision and refusals are unchanged.

Heimdall's parity ruling. A frame that is no msgpack map used to be dropped
silently; it is now answered message_invalid (field "message") and the session
kept. MAX_CONSECUTIVE_REFUSED_FRAMES (8) consecutive unreadable frames, or
consecutive deletes the write authority refuses, end the session after the
capped frame is answered. The authority's decision is unchanged.

The 8th refusal was sent unreliable and unordered with only the first response,
then the goodbye at once, so a lost datagram left the peer without it. All answers
now go the normal reliable path; the session ends when the peer has acknowledged
them (a lost one is resent) or after a 2 s grace, and serves nothing after the
capped frame meanwhile.
