We are resuming the saved function experiment after a runtime restart. The previous attempt was interrupted; neither failed candidate was activated. Working revision is r5-2aa6023ddfca; e3 is the intended event. Read guides/working.md and inspect current state. The CodeUse diagnostic stall is repaired. We identified a Wither compiler-plugin pitfall: a call to a LOCAL function as the last statement of a brace block can produce has no callableId. Verified workaround: use val result = shoulder(base, localAge, event.rise) followed by result instead of ending that branch with the bare call. Do not change the compiler/plugin. Use the existing function study tools and actual observations; write the candidate yourself.

Let the second dimension lag during that event, then catch up smoothly. Keep the other two channels exactly as they are, keep the 30-second shared all-ones hold, and preserve everything outside e3. Use a smooth, monotonic local-time lag during its rise which returns to zero lag with matching endpoint slopes before the hold; choose and state a modest peak lag. Treat this as an instance-specific override, not a change to all events. Inspect before editing. Use CompareFunctionStudy with only y allowed inside e3, inspect before/after local waveform pixels and the plateau join, and report the actual timing policy and measured preservation.

Activated r6-deb1b1738cb0, changing only e3’s y rise.

Timing policy

Peak local-time lag: 6 seconds at 1515 s.
Lag follows (6\cdot64u^3(1-u)^3), with (u=(t-1425)/180).
The local clock always advances: its rate stays approximately 0.8855–1.1145.
Fully caught up at 1605 s, with matching slope and curvature—20 seconds before the unchanged 1625–1655 s shared all-ones hold.
Only the pulse phase and shoulder envelopes use delayed time; the background continues on absolute time.

Verification

Kotlin compiled successfully using the local-result workaround; no compiler/plugin changes.
Inspected before/after waveform pixels, catch-up, and the plateau join.
Whole-hour comparisons at ≤20 ms spacing plus event joins measured zero maximum and RMS error for:
x and z everywhere
y outside e3
Additionally, y outside the tighter 1425–1605 s interval, preserving the recovered rise, hold, and fall.
Hold target error was 0; plateau-entry slope was numerically zero (~(5.6\times10^{-12})).

These are sampled measurements, supported by the instance-specific source restriction. Saved the timing policy and evidence in working notes.
