feat(wave-a): close ADR-011 (SDPO alignment indices) + ADR-012 (review findings)

architect: ADR-011/012/013 + research (alignment-index fix, review-findings closure, LMA channel-ladder)

review+fix: cross-family adversarial ADR review (owed item) + remediation

docs: wave summary — Composer 2.5 data-gen + targeted-RL textual-feedback

feat(datagen): ADR-010 FeatureDeletionEnv synthetic-data subsystem; accepted

feat(hints): ADR-009 layered HintGenerator; accepted

feat(trainer): ADR-008 gate-3 live GRPO+SDPO smoke PASS; ADR-008 accepted

feat(trainer): ADR-008 Dr.GRPO config + SDPO strict-alignment guard

docs(adr): add ADR-008/009/010 (Dr.GRPO+SDPO, layered hints, FeatureDeletionEnv)

research: Composer 2.5 data-gen + targeted-textual-feedback deep-research wave

examples: add sdpo_real_trace_train_smoke — close the forward+backward+step link

Wave 21c: verify PRIME-RL adapter parity against upstream source (byte-for-byte)

Wave 21b: skip zero-signal SDPO on empty-recovery error turns + real-trace validation

Wave 21: close both Wave 20 debt items — chat-template alignment + structural is_error

Wave 20: ModalSpawnExecutor — finish the Modal-backed serverless executor

Wave 19: production-grade SDPO via ComposerDataCollator + adapter + collator fixes

Wave 18: 14 backlog items closed + 3-reviewer cross-family review

Wave 17: close all 5 audit FLAGs + SDPO context alignment + serverless re-exports

Wave 16: install ergonomics + gradient evidence + SDPO end-to-end example

Wave 15: 4-angle multi-model self-critique caught 2 math BLOCKERs in primary loss kernels; fixed against upstream byte-for-byte + GSM8K example + ergonomics

Wave 14: close every Wave 13 review finding + 4 documentation files; Wave 14b: real PRIME-RL parity + multi-process DiLoCo convergence

Wave 13: serverless DiLoCo + replaysim normalization + 3 distillation losses + PRIME-RL + Monarch

Wave 12: close V1-V8 brief — GPU smoke, SDPO firing, real-trace e2e

Wave 11: cross-model adversarial review + honest down-revision

Wave 10 — packaging: composer_replication is now pip-installable

Tidy .gitignore (de-dup *.jsonl, restore section blank lines)

Spike 007: include synthetic_session.jsonl fixture in repo

Wave 7+8+9: spikes 006/007/008 — close vision-validation gaps V2/V5/V8

Wave 7: Phase 2-4 of deep work loop — backlog, parallel research, three ADRs

Wave 6: vision validation self-audit (5/10 to 9/10 in 5 days, no GPU)

Wave 5: full publication-materials drafts (pre-experimental release set)

Wave 4: data collator + loss composition smoke (38/38 tests pass)
