sharkd (the Wireshark daemon) is now the single decode engine — the tshark/PDML path is gone, and without sharkd every replay endpoint returns 501 (no degraded mode: one engine, one rendering shape for the Web UI). - Frame entries gain packet-list columns from sharkd's frames RPC: src/dst/proto/info plus the Wireshark coloring hints bg/fg - range and frames accept ?filter=<display filter>, applied before counting and slicing; invalid expressions are 400 carrying sharkd's original text; filters travel as single argv-style elements, capped at 2000 chars; filtered frames keep their original pcap frame numbers - frame detail returns sharkd's protocol tree with keys renamed into the REST contract (element/label/name/filter_expr/pos+size/expert/ generated/children): a census-verified closed key set, values untouched, unknown keys passed through verbatim, Wireshark-internal hf ids dropped. filter_expr gives the UI click-to-filter; pos/size drives hex highlighting (hex still read straight from the pcap) - one resident 'sharkd -' session per source pcap: lazy spawn, /tmp scratch copy + scratch HOME (hardened profiles), per-request (mtime,size) validation with respawn, LRU bound, per-session lock, per-RPC timeout, bounded close Timeline backbone (gate, record-header scan, merge ordering, canonical ts strings, hex reads) stays plain Python — identity and ordering never depend on the engine.
