fix(quant): a tap is only a tap when its rig is running

Four gates, all bought with the 2026-10-29 incident: the rig's calibration boot died of an OOM,
the chain's health loop expired without failing, and the pusher fed four rounds of 10M tokens
(86 minutes of prefill) into RESTORED PRODUCTION, recording nothing.

- run-qwen38-bf16.sh: --ngram-placement becomes a knob whose calib default is `disk` (the 95.37
  GiB table pin is what starved that boot: 230.22 GiB pinned of 246, 8.06 GiB available) while
  kldref and score keep `ram`. calib writes .rig-boot into the tap dir and retires it on a
  non-zero exit, so a dead boot cannot leave the tap looking rig-authorized.
- calib-push.py: refuses before the first prompt unless the marker exists, names this container,
  and that container is running. With the driver's existing tap-progress gate, a push can no
  longer spend hours feeding an endpoint that is not the rig.
- qwen38-calib-window.sh: the calibration window as a gated chain — stop on a failed phase
  instead of falling through the health wait, bank the 336 GiB reference container into trash
  only when both phases exit 0 and the tap holds grams, and print the whole plan on --dry-run.
- kld-gate-qwen38.sh: two-report mode (candidate vs the served payload) for the disk where the
  172.8 GiB FP8 anchor cannot live, plus the laws the report always carried and the gate never
  read: a p99.9 tail ceiling and every by_source slice passing mean, tail and top-1.
- frank-archon.md: the pipeline laws (marker, n-gram tier, three-metric acceptance) and a Files
  section that names the live campaign instead of the retired swift15 era.

Tests: 587/0 — 13 new behavioral cases (dry-run argv, marker refusals, two-report gate math).

+# qwen38-calib-window.sh — RUNS ON DANKSERVER. The calibration window, and nothing else:
+# boot the BF16 rig, wait until it is actually serving, push the corpus until the engine says
+# the tap is full, stop the rig, restore frank-archon, and bank the reference container.
+#
+# The reference recording is already taken (kld-ref/kld.json exists), so this window is the
+# calibration tap alone — the one job that needs both cards after it. The kldref phase is NOT
+# re-run here: the chained launcher that used to do that moved the banked kld-ref into trash
+# first, which is how a 16-hour phase gets paid for twice.
+#
+# Every phase is gated on the previous one, because the last time this ran unguarded
+# (2026-10-29) the rig's boot died of an OOM, the health loop quietly fell through, and the
+# pusher fed four rounds of 10M tokens into RESTORED PRODUCTION with nothing recorded:
+#
+#   1. the runner must still be alive and its container must answer /health, or this script
+#      kills it, restores the service and exits non-zero — no push, ever;
+#   2. the pusher refuses on its own unless the rig wrote its marker into the tap dir, the
+#      marker names this container, and the container is running (scripts/calib-push.py
+#      --tap-marker), so a second lock survives a mistake in this file;
+#   3. the reference container is banked into trash only when BOTH the serve and the push
+#      exited 0 and the tap dir holds grams. The checkpoint that reproduces it stays.
+#
+# knobs: Q38_WINDOW_CALIB_CORPUS (calib-7168.jsonl — the re-chunked file the rig's pool can
+#        hold), Q38_WINDOW_HEALTH_TIMEOUT (seconds to wait for /health), Q38_WINDOW_ROUNDS

+The three tools move the same two shapes — a JSONL of prompt records and a

+### The quantization pipeline
+
+- **A calibration tap is only a tap when the rig that opened it is running.** The runner writes
+  `.rig-boot` into the tap dir (container, image, pid) and retires it when its boot exits non-zero;
+  `calib-push.py` refuses without that marker, refuses when it names another container, and refuses
+  when the named container is not running; `qwen38-calib-window.sh` stops on a failed phase instead
+  of falling through its health wait. All three exist because on 2026-10-29 the unguarded chain's
+  rig boot died of an OOM, the health loop expired without failing, and the pusher fed four rounds
+  of 10M tokens into **restored production** — 86 minutes of live prefill that recorded nothing.
+- **The n-gram table's pin is what starves a rig boot, and the tier is a knob.** On the BF16 payload
+  the table is 95.37 GiB, `--ngram-placement ram` pins it, and the calibration boot died at
+  `startup stopped: out of memory` with 230.22 GiB pinned of 246.07 GiB and 8.06 GiB available —
+  while the reference recording and every score boot succeeded at the same pool and slot count.
+  Calibration only needs the routed weights prefilled, so it reads the table from the container's
+  file tier (`--ngram-placement disk`); kldref and score keep production's placement, because their
+  numbers are only comparable at an identical shape.
+- **Acceptance is three metrics and every slice, not a mean.** `scripts/kld-gate-qwen38.sh` grades
+  mean KL, the p99.9 tail, top-1 agreement and every `by_source` slice (code, prose, tools):
+  a mean can hide a few positions taking the whole hit, and an overall win can be bought by
+  regressing one distribution. The FP8-native anchor is an interval, not a requirement — without
+  the 172.8 GiB fetch the gate runs in two-report mode (candidate vs the served payload) and says
+  so on its first line.
