Confirms the full scheduler test suite passes with no regressions
(63/64; sole failure is the pre-existing, unrelated bug-1758) and that
the feature works correctly at realistic scale. Built a synthetic
multi-round replay mirroring the original motivating scenario (a
JOB_PUSH immediately followed by several JOB_UPDATE/JOB_STATE_CHANGE
events for the same job, all sharing one rendered second/session) and
ran it through the real interactive binary in both step and continue
mode: a 6-event same-context run and a 4-event structural run each
collapsed to exactly one preamble line, an elapsed-time context change
and a session-only context change (same rendered second, different
session) each correctly forced a fresh preamble - confirming the
dedup key is genuinely the (timestamp, session) pair, not either
field alone. Continue mode's pre-existing, unrelated Event Echo Gate
correctly suppressed routine events throughout. A non-interactive
batch run of the same fixture produced the identical single decision
step/continue mode already showed, confirming no scheduling-decision
divergence.
This is the final task of the scheduler-sim-step-verbosity spec; all
implementation tasks (1.1-2.2) are now complete.

Verified (full regression build/test pass, a per-file diff of every
pre-existing REPL test file against the pre-feature baseline,
repl.c's command dispatch confirmed byte-identical, and a two-worktree
step-mode transcript diff against a synthetic fixture with both a
same-context and a differing-context event pair) that: no pre-existing
test assertion was touched, no top-level command changed, and the
transcript diff shows exactly the two same-context preamble lines
removed with every other line - including both events' own content -
byte-identical to the pre-feature baseline. The new cache fields
(last_echo_ts_human/last_echo_session) are read/written exclusively
inside repl_print_event_summary(), confirming the feature is
display-only and cannot affect scheduling decisions or simulation
state (Requirement 2.4). The sole test failure in the full suite
(test_job_rusage_reconciles_mem_reservation_against_usage) is
confirmed pre-existing and unrelated (bug-1758). Read-only validation
task; no production or test code changed.

repl_print_event_summary() (repl_break.c) now compares the candidate
rendered timestamp and displayed session number against a new cache
on xce_sched_repl_state_s (repl_internal.h: last_echo_ts_human[32],
last_echo_session) before printing the "[sim] t=... session=..."
preamble. It prints and updates the cache only when either value has
changed, or no preamble has been printed yet this session (the cache's
zero-initialized default, which no real echoed event can produce);
otherwise the preamble is skipped and the cache is left untouched. The
event's own content line prints unconditionally either way
(Requirements 1.1-1.4, 2.2).
All 6 RED-phase tests (task 1.1) now pass, including the critical
raw-vs-rendered nuance test (Requirement 1.3). No regressions in the
Event Echo Gate suite or the sibling spec's breakpoints-inspection
suite (test_step_echoes_events_before_session_decisions specifically
confirmed still passing under the new dedup behavior).
repl_break.c grew from 949 to 980 lines (+31, 3.3% over the residual
already accepted in scheduler-sim-repl-verbosity task 9.2). Review
judged this small growth as accepted without a fresh empirical split
test: task 9.2's own split experiment (a larger +44-line growth)
already found extracting this file's lookup-table domain reaches only
838 lines (still over cap) while requiring 22 white-box test files'
#include lines to change - disproportionate churn this smaller
increment would only re-confirm.

Adds 6 failing tests for the Event Echo Preamble Deduplicator
(Requirements 1.1-1.4, 2.2): a second echoed event sharing its
predecessor's rendered timestamp+session omits its preamble; two
events across a session boundary both print their own preamble; the
critical raw-vs-rendered nuance (Requirement 1.3) - two events whose
raw nanosecond timestamps genuinely differ but whose rendered,
second-granularity timestamp and session are identical still dedupe,
with a fixture-premise self-check proving the two raw values really
do render identically; the first echoed event in a fresh session
always prints its preamble; a structural event under continue mode
after suppressed routine events follows the same rule; event content
and ordering are unaffected regardless of the preamble decision.
Lands in a new test_repl_step_verbosity.c (1010 lines, 6 tests) rather
than extending test_repl_event_echo.c (705 lines) - proactive split
per this file family's established practice, since appending would
have pushed that file well past the project's ~1000-line trigger.
Registered in testsuite/meson.build. No production code touched.

Follow-on to scheduler-sim-repl-verbosity: collapses the REPL's
per-event "[sim] t=... session=..." preamble to print once per
distinct rendered (timestamp, session) run of consecutive echoed
events, instead of once per event, in both step mode and continue
mode's structural-event echo. Requirement 1.3 deliberately keys the
dedup on the rendered, second-granularity timestamp rather than the
raw nanosecond clock value, which ticks on every event and would
otherwise never repeat -- confirmed against a real user-supplied
transcript before writing requirements (see research.md). Requirement
2 preserves event selection, ordering, content, every other REPL
command, and all scheduling decisions/state exactly as
scheduler-sim-repl-verbosity's Requirement 5 already established.
Generated via kiro-spec-quick (single-pass, no approval gates) with
an inline requirements review gate, an inline design review gate, and
an independent task-graph sanity review (one NEEDS_FIXES round,
repaired: added file-size watch bullets to tasks 1.1/1.2 per
design.md's own housekeeping directives).
