Every event frame through :func:`server.write_json` (hence ``_emit``) gets a per-session monotonic ``seq`` and lands in a small ring per session; a reconnecting client calls ``session.events.since`` with its last seen seq and gets everything newer. Invariants: stdio TUI unaffected (``seq`` only on event frames; Ink ignores unknown keys); one lock guards counters + buffers, and write_json already serializes per-transport writes so stamping cannot reorder frames; memory bound = _REPLAY_BUFFER_MAX events AND _REPLAY_BUFFER_BYTES_MAX frozen UTF-8 payload bytes per session, _REPLAY_PROCESS_BYTES_MAX frozen UTF-8 payload bytes across at most _REPLAY_SESSIONS_MAX sessions, oldest evicted FIFO (their seq/truncation counters are retained so a revisited session stays monotonic within the epoch, #100122). Evicted or never-retained (oversized) frames leave a truncation watermark so a reconnecting client refetches instead of trusting a replay with holes. A torn-down session's ring is freed at teardown (``forget_session``) and never rebuilt by late frames. ) annotationsN) OrderedDictdequeizOrderedDict[str, deque]_replay_bufferszdict[str, int]_replay_buffer_bytes_replay_evicted_through_replay_next_seqzset[str]_replay_forgottencV^8dQhRR/#)returnstr)formats"=/home/ubuntu/.hermes/hermes-agent/tui_gateway/event_replay.py __annotate__r5scc\#)z=Opaque token identifying this server process's seq numbering.) _REPLAY_EPOCHrrr replay_epochr5s rc V^8dQhRRRR/#)r paramsdictr bytesr)rs"rrr:s4ErcV\P!VRRR7PRRR7#)zLSerialize one replay snapshot before the caller can mutate its object graph.F) ensure_ascii separatorsutf-8 surrogatepasserrors),:)jsondumpsencode)rs&r_freeze_paramsr&:s- ::f5Z H O O P rc$V^8dQhRRRRRR/#)r payloadrseqintr rr)rs"rrrAs!%cdrc\\P!VPRRR74pWR&V#)zKRebuild a client event object and restore the server-owned sequence number.rrrr))r#loadsdecode)r(r)events&& r _thaw_paramsr/As) JJw~~go~F GE%L Lrc V^8dQhRRRR/#)r objrr Noner)rs"rrrHs22d2t2rc VPR4R8wdR#VPR4p\V\4'gR#VPR4;'gRpV'gR#\V4p\ V4p\ ;_uu_4\ PV^4^,pV\ V&WQR&V\9dV\V&RRR4R#\PV4pVfX\4;p\V&^\V&\ \4\8d$\\\\444K;V\ 8g V\"8dV\V&RRR4R#VP%WSV34\V;;,V, uu&\&V, s\ V4\(8g\V,\ 8dcVP+4wrxp \V;;,V ,uu&\&V ,s\-\PV^4V4\V&K\&\"8d\P/4FpwrV 'gKV P+4wrxp \V ;;,V ,uu&\&V ,s\-\PV ^4V4\V &K KRRR4R# +'giR#;i)zSStamp one outgoing event frame (mutates obj in place) and record a frozen snapshot.methodr.Nr session_idr))get isinstancerr&len _replay_lockrr rrrr_REPLAY_SESSIONS_MAX_drop_ring_lockednextiter_REPLAY_BUFFER_BYTES_MAX_REPLAY_PROCESS_BYTES_MAXappend_replay_total_bytes_REPLAY_BUFFER_MAXpopleftmaxitems) r1rsidr(sizer)buf evicted_seq_event evicted_size evict_sid evict_bufs & r _stamp_eventrOHsK wwxG# WWX F fd # # **\ " ( (bC V$G w * *d5N.N+. #C ( !

Caller holds ``_replay_lock``. The ring goes, the session's seq numbering stays (#100122): a revisited session continues from its high seq instead of restarting at 1 under clients' still-held watermarks (a reset seq is invisible to dispatchIfNewer, so replay AND live frames silently vanish). The truncation watermark is raised to the latest stamped seq: a client holding any older watermark has a gap and must refetch history instead of trusting the new tail.
