…ousResearch#77, NousResearch#78)

Two binding mechanisms for the worker-discipline gaps the 2026-06-10
v6.7 validation chain surfaced. Both close hermes-jarvis#77 (workers
don't reach for x_fast_justified when fast) and hermes-jarvis#78
(workers heartbeat forever past elapsed floor).

Paired with hermes-jarvis#80 (SOULs decision tree).

## Layer 1 — progressive RuntimeFloorViolation messaging

RuntimeFloorViolation now carries prior_floor_rejections and
floor_elapses_at. message() branches on the rejection count:
- 0: standard 'Either... or...' message with explicit
  seconds_remaining
- ≥1: escalated 'REJECTED #N — same inputs, same result. You must
  choose ONE of: (A) Wait Xs... (B) Opt out NOW with metadata=...'

_v6_7_run_completion_gates seeds the count from
_v6_7_count_prior_floor_rejections (LIKE-matches the JSON 'kind'
field to avoid false-positives on prose).

## Layer 2 — heartbeat surfaces floor_status

_v6_7_heartbeat_floor_status computes elapses_at, seconds_remaining,
retry_complete_now, floor_seconds from the task's started_at + role
floor. _handle_heartbeat threads it through so workers see
'wait Xs vs use opt-out' as actionable data.

## Self-review fixes baked in

- LIKE pattern anchored to JSON kind field (no summary_preview
  false-positives)
- verify_runtime_floor docstring documents reclaim semantics
  (started_at = first claim; reclaim doesn't reset)
- Dead for-loop + deferred import removed
- Helper renamed to _v6_7_heartbeat_floor_status (with public alias
  for back-compat)
- 'REJECTED FOR THE 2-th TIME' → 'REJECTED #2' (machine-readable,
  no grammar awkwardness)

## Tests

123 in test_kanban_completion_gates.py pass. 219/219 across full
v6.7+v6.8 + adjacent regression set, zero failures. Includes 4
gap-fill tests from self-review (summary_preview false-positive
guard, multi-violation single-count, unknown-task safety, negative-
seconds clamping).
