Stage 4 onto main: the compliance proof notebook (corrective for #11) - #12
Merged
Conversation
tools/notebook/itu_dump.cpp re-runs the full Stage 3/3b battery on the pinned compliance chain (the test suite's own itu_chain.h machinery and meters) and dumps every measured number and level trace as JSON; the scenario recipes mirror the gtest rows line for line, so the notebook renders the numbers the assertions gate. CSS generation through the NOTE 2 resampler dominates the runtime, so the dump memoizes make_css_at (byte-identical output verified against the uncached run; the signal layer itself is untouched). tools/notebook/build_itu_compliance.py assembles and executes notebooks/itu_compliance.ipynb: nine requirement-group sections, a requirement/measured/margin table per section, convergence curves vs the recommendations' time masks, double-talk rows vs the P.340 windows, and an honest figure of the re-convergence deviation. The notebook's first cell builds the dump (MUTAP_BUILD_ITU_DUMP, dedicated build-itu/ tree) and re-measures everything live (~6 min, deterministic seeds).

Build product of tools/notebook/build_itu_compliance.py — 13 figures, 8 requirement/measured/margin tables, every number re-measured live by the itu_dump battery at both required rates.

Summary
Corrective PR, same situation as #8: #11 merged into its stacked base branch (
claude/itu-stage3b-g168) instead ofmain— the base was never retargeted after #10 merged, so main never received Stage 4. This PR cherry-picks #11's three commits (unchanged) onto current main:ITU Stage 4: the compliance proof notebook builder and measurement dump—tools/notebook/itu_dump.cpp(the C++ battery reusing the test suite's scenario machinery, newMUTAP_BUILD_ITU_DUMPoption) +tools/notebook/build_itu_compliance.py+ docs (README, compliance matrix "Stage 4 delivered", HANDOFF).notebooks/itu_compliance.ipynb: the executed compliance proof— 13 figures, 8 requirement/measured/margin tables, every number re-measured live.HANDOFF: Stage 5 Max-half done-note + the chain-preset core follow-up.Full description and verification notes in #11.
Cherry-picked clean, no conflicts. After this merges, the stage branches (
claude/itu-stage3b-g168,claude/itu-stage4-notebook,claude/itu-stage4-main) can all be deleted in the UI (remote deletion is blocked from this session).🤖 Generated with Claude Code
