The salvaged helper was appended to the gateway/run.py facade; new behaviour
belongs in a topical sibling. agent/session_activity.py already owns the
activity-snapshot contract the three render sites read from, so the formatter
moves there as format_iteration_progress and the three call sites import it at
module level instead of late-importing the facade.
Tests trimmed to the salvage bar (<= 2 invariant tests per fix): one
parameterized contract on the helper (unbounded/None hide the ceiling, a real
budget keeps N/M) plus the contributor's end-to-end busy-ack test through the
real render path. The per-site heartbeat/timeout tests exercised the same
helper through mocks and are dropped; evals/gateway_status_render/
iteration_ceiling_ab.py drives all three real render sites with a real AIAgent
for before/after evidence (3 sentinel leaks on main -> 0).
Related: #103109 (same fix, same target module; credited in the PR),
#102845 (third render site, closed by its author in favour of #102817).
- tests/agent/test_session_activity.py asserts against
ACTIVITY_DESCRIPTION_MAX instead of the literal 120.
- The session-stall WARNING log line names its config knob
(agent.session_stall_timeout) so operators can find the setting.
- hermes_state.py: collapse the triple blank line near line 191.
- hermes_cli/status.py no longer imports the private
hermes_cli.main._relative_time: the helper moved to a public home
(hermes_cli.timefmt.relative_time); main._relative_time stays as a
thin back-compat wrapper (sessions_cmd and external patchers keep
working).
Three mechanisms to detect and notify when gateway sessions stall silently:
1. Mid-turn activity heartbeats stamped to SessionDB so hermes sessions list
and hermes status show progress during long turns without new message rows.
2. Stall watchdog: when a busy session has pending inbound and the shared
activity clock is idle past agent.session_stall_timeout (default 300),
log a WARNING and notify the user once to try /new. Notify-only; does
not kill the turn.
3. Compaction timeout: fenceless compress_context callers get a progress-aware
host budget (compression.context_timeout_seconds default 120 idle,
compression.context_total_ceiling_seconds default 600 ceiling). On timeout,
cancel via commit fence, skip compaction without dropping messages, and
continue the turn.
Closes#72016 (slices 1-3; slice 4 cumulative SSE stream-retry deadline
remains a follow-up).
