docs(wave2): archive point-in-time wave reviews + dated review bundles
Move historical, point-in-time artifacts into _archive/ (preserving git history via rename) and leave one-line redirect stubs at every original path so nothing 404s — including the prose references baked into immutable accepted ADRs (ADR-007/008/012) and off-limits spike verdicts, which cannot be edited to point at the new location. Docs-only; no source files touched. Moved -> docs/research/_archive/ : WAVE_7_10_FINAL_REVIEW, WAVE_13/14/15_FINAL_REVIEW (cross-model reviews). Moved -> docs/_archive/ : DEEP_WORK_LOOP_LOG, WAVE_COMPOSER_DATAGEN_RL_2026-05-29, and the two dated review bundles (reviews/cross-family-adr-008-009-010-2026-05-29/ and reviews/final-verify-deep-work-2026-05-29/). Each origin path keeps a redirect stub pointing to the archived copy and to the current source-of-truth (METHODOLOGY / BACKLOG / V1_V8_COVERAGE / ADRs). Added docs/_archive/README.md and docs/research/_archive/README.md indexing what was archived and why ("point-in-time, superseded by current d…f00833d -
docs(wave1): correctness pass — channel-3 provenance, gap honesty, dead links
Propagate ADR-014 ground truth into the living docs and fix every dead relative link. Docs-only; no source files touched. Provenance (Fact A) — stop blurring the additive trace-replay-DPO channel into Cursor's recipe: - README v0.1 roadmap cell, HF_REPO_LAYOUT v0/v1 variant rows: reframe "Composer recipe" = channels 1 (Dr.GRPO) + 2 (SDPO) only; trace-replay is the framework's own addition (link ADR-014). Gap honesty (Fact D) — do not imply the full A1-A4 LMA ladder is runnable: - VISION_VALIDATION status banner + ALTERED_MINDS_TIE_IN Phase-3: only A1 (GRPO-only) has a real Modal runner; A2/A3/A4 are scaffold + plan-builder only, blocked on dataset construction. Real 8B run is additionally budget-gated. PO menu / strip_thinking / main-lag (Facts B, E, F): - VISION_VALIDATION: base RL objective is a selectable menu (default Dr.GRPO) per ADR-014, not hardcoded. - ALTERED_MINDS_TIE_IN: note SDPO requires strip_thinking=False on real traces (~67% of error-recovery turns are…20e3bd9

feat(trainer): policy-optimization objective MENU (ADR-014)
Adds make_po_config(objective=..., **overrides) — RL's base objective is no longer hardcoded to Dr.GRPO. Six selectable named presets over trl 1.5.0's verified GRPOConfig knob-space (introspected the installed package, not a GitHub snapshot): grpo | vanilla GRPO (std-norm advantage) dr_grpo | DEFAULT; no length-std bias (Composer 2.5's base objective) bnpo | batch-normalized dapo | decoupled clip-higher (epsilon_high=0.28) + overlong mask + KL off gspo | sequence-level importance ratio (Qwen3; long-CoT / MoE stable) cispo | detached-IS REINFORCE (every token keeps a gradient; MiniMax-M1) Every preset is PURE CONFIG (trl already implements each loss_type branch + importance_sampling_level/epsilon_high) — no custom _compute_loss. Drift guards assert loss_type / IS-level / epsilon_high actually applied so a preset can't silently degrade (e.g. GSPO with IS overridden back to token raises). 10 unit tests green against real trl 1.5.0.

docs(adr-013): close acceptance-gate boxes 1-5; only user-gated spend remains
The LMA-side runner scaffold (the one outstanding non-budget-gated box) now exists in the sister repo: llm-mental-alterations/composer_replication_runs/ with 15 green mock-driven tests (collect+pass with no torch/trl/modal/framework installed), documented in LMA ADR-0017. Marks boxes 1-5 done; the only open item is the explicit user go/no-go on real LMA-checkpoint / Modal budget spend.7b34ebf -
fix(phase-8): close all 5 cross-family final-verify findings + regression tests
The deep-work-loop exit gate (2 independent confirmations). A final 3-family scatter of the session diff found and we fixed: - [P0 latent] SDPO sentinel-mask used only student_response_valid; now requires BOTH valid masks AND non-sentinel indices (a future divergent teacher tail could have distilled against clamped position 0). - [P1 convergent, GPT-5.5+Gemini] curriculum shared one n_effort denominator for turns+think_tokens; split into independent n_turns/n_think counters. - [P1] docker E2E test ran pip-install under --network none (would fail when the gate activates); replaced with stdlib python -c expression runner, no network. - [P1] MMLU reward: Answer: A or B hedge scored full credit; _HEDGE_RE now penalizes it as multiple-answers. - [P1] HackMonitor read-markers matched import in important / cat in concatenate and scanned the agent patch as read-evidence; whole-word regex + exclude patch/diff payloads from BOTH layers (a legit patch can no longer self-incriminate…678d10b -
feat(b4-gpu+b6): GPU train-proof on A10G + docker-gated substrate E2E test
B4-GPU: modal_b4_gpu_smoke.py ran real Qwen2.5-0.5B-Instruct on a Modal A10G in bf16, 30 steps of the real 3-channel composition. PASS: all-finite, SDPO channel fired nonzero (max JSD 0.1855), loss converged 4.7262 -> 0.0050 monotone. This is the genuine "it trains on GPU" proof the CPU smoke could not give. Result + curve in gpu_smoke_result.json; README documents both CPU and GPU proofs. B6: test_docker_substrate_e2e.py — the docker-gated 4-gate substrate-inversion E2E now EXISTS (was only referenced). Runs the gates against a real python:3.11-slim container + real subprocess pytest on a minimal synthetic feature-deletion task, plus a cache-scrub-in-container test. Skips cleanly with no Docker (2 skipped here), runs the moment a Docker host executes the suite. ADR-010 [~] gate updated: mechanics gate is now ready-to-close, not just wired. Cost: ~1-3 USD A10G. No LMA budget touched.c009712 -
feat(wave-b): ADR-013 LMA integration + B4 end-to-end SDPO-fires proof + doc refresh
ADR-013: composer_replication/integrations/altered_minds/ (generic, framework-side) - MMLUFormatReward: structured-answer reward, scores only the final letter (not rationale style), unparseable/multiple-answer penalties, option-order randomization, always-C exploit detectable via logged option distribution. - dual_kl_logger: KL(policy||altered-init) AND KL(policy||unaltered-base) as the washout-vs-amplification instrument (neither optimized). - channel_ladder_configs: A0-A4 isolated-channel ladder (alpha=0.02/beta=0.05), replacing the uninterpretable combined alpha=0.2/beta=0.4 recipe per the cross-family research critique (SDPO can AMPLIFY an altered model). B4: examples/altered_minds_channel_ladder/run.py PROVES the SDPO channel FIRES nonzero (JSD=0.0565, grad flows) through the REAL shipped collator alignment indices — the thing the old smoke could not show (it only proved init).

feat(wave-a): close ADR-011 (SDPO alignment indices) + ADR-012 (review findings)
B1/ADR-011: collator emits student/teacher_response_idx + valid masks via _mask_to_padded_indices; loss sentinel-masks padding. Strict SDPO no longer raises against the real collator (the regression my review-fix introduced). B2/ADR-012: - k1-KL: found TRL 1.5.0 uses k3 not k1; corrected docstring honestly + documenting test. - hint routing: style/communication/effort sites now reach the judge (error-kind aware). - HackMonitor: added patch-provenance layer defeating string-concat obfuscation; ADR-010 language corrected AST->signature+patch-provenance. - curriculum: optional turns/think_tokens effort signals, backward-compatible. 210 passed / 16 skipped (was 192). Two Opus-4.8 workers in parallel.d02d724 -

review+fix: cross-family adversarial ADR review (owed item) + remediation
Ran the owed 5-family adversarial review of ADR-008/009/010 (unblocked once OpenRouter credits were restored). 4/5 clean reviews (GPT-5.5, Gemini 3.1 Pro, DeepSeek V4 Pro, Grok 4.3; Kimi starved its token budget). Verdicts: ADR-008 3-REJECT/1-fix, ADR-009 unanimous-fix, ADR-010 3-REJECT/1-fix — all REJECTs were "accepted-status outran the evidence," not "design wrong." The review caught a real policy-corrupting P0 the solo pre-mortem missed: the SDPO alignment guard was a shape-check, so hint-shifted teacher tokens could silently misalign and distill garbage into the policy. Verified every convergent finding against code, then fixed (192 pass/16 skip, was 187): - SDPO alignment (composer_trainer.py): require collator-emitted student_response_idx/teacher_response_idx; gather aligned post-hint logits before JSD; strict-mode raises on missing/mismatched indices. Tests rewritten to the corrected contract (different-length sequences now exercised). - Sandbox scrub (sandbox.py): boo…185cce2 -

feat(datagen): ADR-010 FeatureDeletionEnv synthetic-data subsystem; accepted
Track A of the deep-work-loop — Composer 2.5's named synthetic-data generator (Feature Deletion) as a reusable subsystem. New composer_replication.datagen: - schema.py: FeatureDeletionTask (broken_repo + FAIL_TO_PASS reward target + PASS_TO_PASS functional guard; golden_diff HELD OUT of repr/observation). - sandbox.py: Sandbox Protocol + FakeSandbox (unit tests) + LocalSubprocessSandbox (real); SANDBOX_DENYLIST blocks find/strings/unzip/decompilers/git (the tools Composer's reported reward-hacks used to recover deleted signatures). - monitor.py: HackMonitor — flags cache/bytecode-provenance hacks so the grader masks reward (defense-in-depth behind the sandbox lockdown). - curriculum.py: DifficultyCurriculum — online pass-rate gate; up-weights the ~0.5 frontier (w ∝ p(1-p)), retires aced tasks, quarantines all-fail tasks (raw rate, not smoothed). Implements the blog's "select for harder tasks dynamically". - validator.py: 4-gate solvability validator (baseline-green / del…9336af3 -
feat(hints): ADR-009 layered HintGenerator; accepted
Track B of the deep-work-loop. Extends hint_generator.py from a flat dispatch registry into a layered, cost-ordered HintGenerator behind a typed Protocol — the SDPO textual-feedback hint source (Composer 2.5's hint mechanism is unstated in every Cursor artifact; this is our reconstruction). Layers (tried cheapest-first, first non-None wins): 1. TemplateHintGenerator — the existing 5 templates (free, deterministic; byte-identical to dispatch(), preserved). 2. RawErrorHintGenerator — raw env/tool error text as the hint (free; covers any message-bearing site templates miss). SDPO "environment feedback as conditioning signal". 3. LLMJudgeHintGenerator — <=2-sentence corrective hint via an injected complete() callable (optional, OFF unless provided; in-memory + disk cache keyed on error-context hash; covers style/communication/effort). CompositeHintGenerator.as_collator_hook() returns a callable matching the existing CollatorConfig.hint_generator signature (…84740d4 -
feat(trainer): ADR-008 gate-3 live GRPO+SDPO smoke PASS; ADR-008 accepted
The composer_grpo_sdpo_smoke instantiates a real trl.GRPOTrainer via ComposerReplicationTrainer on Qwen2.5-0.5B with the Dr. GRPO config (loss_type=dr_grpo, scale_rewards=none, num_iterations=1) and alpha_sdpo=1.0, runs 1 step, and confirms loss/sdpo_kl is logged — the SDPO channel is wired into the live Dr. GRPO loop. PASS. Surfaced + fixed a real API drift: TRL 1.5.0 dropped GRPOConfig.max_prompt_length. All 4 ADR-008 acceptance gates green -> status proposed->accepted; gate checkboxes ticked with evidence; index updated.2a34df4 -
docs(adr): add ADR-008/009/010 (Dr.GRPO+SDPO, layered hints, FeatureDeletionEnv)
Phase-4 of the deep-work-loop. Three proposed ADRs translating the Composer 2.5 data-gen + targeted-textual-feedback research into durable decisions, each with mechanized acceptance gates (status stays `proposed` until gates green): - ADR-008: target Dr. GRPO (length-std off, no std-norm, k1 KL, Adam, single-epoch — per arXiv:2603.24477) and host the live SDPO channel in the TRL ComposerReplicationTrainer. amends ADR-006 (SDPO needs full logits -> TRL-only; PRIME-RL hosts channels 1+3). preserves ADR-007. - ADR-009: layered HintGenerator (template -> raw-error -> LLM-judge -> SDPO sibling-bootstrap) behind a typed Protocol; preserves the existing templates + CollatorConfig.hint_generator hook. - ADR-010: FeatureDeletionEnv synthetic-data subsystem inverting OSS SWE substrates (SWE-bench-Lite/SWE-Gym/R2E-Gym/SWE-rebench) + online difficulty gate + reward-hacking safeguards.

Wave 18: 14 backlog items closed + 3-reviewer cross-family review
Polish wave grinding down 14 P0/P1/P2 items from Wave 7 audit + Wave 11/12 self-critique + Wave 16/17 deferrals. Two passes of 3-reviewer cross-family review (Gemini 3.1 Pro / Grok 4.3 / Sonnet 4.6) caught 6 real issues in round 1; round 2 verified all fixed plus 2 new flagged items addressed. Doc honesty (P0): - README.md scoping change at line 29: dropped "any HuggingFace base model" for the more honest "any HF causal LM with a chat template (Qwen, Llama, Mistral, DeepSeek, Phi, Gemma families)". Added qualifier that Spike 006 zeroed the SDPO channel due to shape misalignment, so SDPO is verified via the integration test suite + end-to-end examples, not Spike 006. - spikes/005-integrated-trainer-skeleton/verl_path/README.md NEW — explicit STATUS: design-only marker per Wave 7 audit Objection 3.

Wave 17: close all 5 audit FLAGs + SDPO context alignment + serverless re-exports
Three-track follow-up to Wave 16, with cross-model review (gemini-3.1-pro APPROVED, grok-4.3 surfaced one BLOCKER that verified false-positive empirically, deepseek-v4-pro burned all max_tokens on hidden reasoning producing no visible output): Wave 17a — serverless package re-exports (real code bug) composer_replication/diloco/serverless/__init__.py now re-exports ModalExecutor and HFJobsExecutor alongside LocalProcessExecutor. The package docstring already documented `from composer_replication.diloco.serverless import ModalExecutor` as the public API but the import would have failed because the names weren't in __init__.py's import list or __all__. Both modal.py and hf_jobs.py import-safely (they don't import the optional `modal` / `huggingface_hub` packages at module level — those are deferred to class method calls), so adding the re-exports doesn't introduce a new dependency. Pinned by a regression test (test_public_reexports_include_all_executors in test_s…a84c060 -
Wave 16: install ergonomics + gradient evidence + SDPO end-to-end example
Five-track polish wave with mandatory cross-model adversarial review (deepseek-v4-pro + gemini-3.1-pro-preview, route-fidelity-verified via direct-urllib scatter; reviewers caught 2 real bugs that BOTH made it into the staged diff and would have shipped without the review): Wave 16a — Install ergonomics (extras pinning) pyproject.toml dropped three extras whose lower bounds were unsatisfiable on public PyPI and would have blocked any fresh user: - monarch>=0.4.1: PyPI 'monarch' tops out at 0.1.11 and is unrelated to Meta's actor framework; the real Monarch ships as torchmonarch-nightly with platform constraints. - prime-rl>=0.5: 'prime-rl' is not registered on PyPI at all; Prime Intellect publishes from source only. - data-juicer>=1.0: 'data-juicer' is not registered on PyPI; the closest match (py-data-juicer) has broken transitive deps. All three integrations import lazily, so the framework still loads cleanly without them. docs/TROUBLESHOO…c0a5ab7 -
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
PHASE 15a: 4 parallel adversarial reviewers, each with different framing to maximize independent-angle coverage: - MATH (Opus 4.7): cloned upstream OPSD/TAID/PRIME-RL/SimPO, did line-by-line diff. Found 2 BLOCKERs all 8+ prior reviewers missed. - TESTS (Opus 4.7): scrutinized 3 high-stakes test files for weak assertions. Found PRIME-RL parity test silently never runs; bit-exact test uses allclose; entropy-OPD test is pure smoke. - DOCS (Opus 4.7): audited 6 major docs + ADRs. Found test-count drift (77/107/124 vs 145), compose_loss kwarg drift, stale "Deferred to Wave 14" claim, PRIME-RL test count 10 vs 16. - USER-JOURNEY (Opus 4.7): walked "RL-finetune Qwen-7B on GSM8K" end-to-end. Scored framework 2.4/5 with Real-Task-Path = 1/5. #1 friction: NO GSM8K example anywhere. All 4 reports saved to /tmp/wave15_*.md.

Wave 13: serverless DiLoCo + replaysim normalization + 3 distillation losses + PRIME-RL + Monarch
Expanded the brief mid-deep-work-loop to address the user's request for serverless training-system support, replaysim dataset normalization, deeper self-distillation paper coverage, and Meta's PyTorch agentic stack tie-ins. NEW MODULES (35 tests passing): - composer_replication.distillation: SimPO (arXiv:2405.14734), TAID (arXiv:2501.16937), Entropy-Aware OPD (ICLR 2026 spotlight). 17 unit tests covering scalar/differentiable/scheduler-monotonicity and boundary-condition correctness against paper formulas. - composer_replication.diloco.serverless: ServerlessExecutor Protocol + ObjectStoreAllReduce (fsspec-backed; works with file:// + s3:// + hf:// + gs:// + az://) + LocalProcessExecutor (working) + ModalExecutor / HFJobsExecutor (skeletons, raise NotImplementedError). 9 tests including 3 multi-process tests pinning the allreduce barrier with mean-of-{0,1,2}=1 + mean-of-{0,100,200}=100 across two consecutive rounds. - composer_replication.replaysim: data-juicer adapte…b266c31 -
Wave 12: close V1-V8 brief — GPU smoke, SDPO firing, real-trace e2e
Addresses cross-model review priority items 3, 4, 5, 9 — the ones that materially close the original V1-V8 brief. Wave 12 deliverables: 1. **Spike 002a-mini-gpu-smoke** (NEW directory) — closes "zero GPU evidence": - 50-step Qwen2.5-0.5B-Instruct training run on local RTX 5090 (sm_120, Blackwell), bf16, in 35 s wall-clock total - Loss 0.7354 → 0.00034 (99.95% reduction), all grads finite, peak VRAM 5.31 GB (well under ADR-001's 8 GB target), median 480 ms/step - Captures per-step memory + step-time + finite-grads in results/gpu_loss_curve.csv + results/gpu_verdict.json - ADR-001's local-5090 choice now empirically verified (vs ~3-5 min cold-start cycle estimated for Modal L4) - Resolves cross-model review item #4 2. **Spike 006-strict** (`tests/test_strict.py`) — closes the tautology critique: - test_alternating_batches_loss_decreases: 10 steps alternating between factorial + binary_search variants.

Wave 11: cross-model adversarial review + honest down-revision
Phase 11 of the deep work loop ran a cross-model adversarial review on the Wave 7-10 work. The review (anthropic/claude-opus-4.7, separate session) found 10 substantive flaws including 2 BLOCKERs: 1. **Scorecard inflation** — initial self-claim was 5/10 → 9/10, honest re-scoring is 5/10 → 7/10 ✅ + 1/10 ⚠️ + 2/10 ❌-spirit. 2. **Spike 008 acceptance criterion silently redefined** — BACKLOG required "2 replicas converge"; what shipped is "1 replica + passthrough no-op allreduce." The recon doc's "ready-to-paste 2-replica pattern" hits a single-process post-hook sequencing bug. Both BLOCKERs addressed in this commit: - docs/research/WAVE_7_10_FINAL_REVIEW.md — full 423-line review committed. - docs/VISION_VALIDATION.md — replace 9/10 self-claim with honest 7/10 re-scoring + per-test caveats acknowledging the spirit-failures of tests 6/8/10. Explicitly notes "the framework as of this commit has zero GPU evidence of any kind." - spikes/008-streaming-diloco/verdict.md — s…f16fa23 -
Wave 7: Phase 2-4 of deep work loop — backlog, parallel research, three ADRs
Imports the gap-closer wave from VISION_VALIDATION.md as a structured backlog, records the deep work loop log, and locks three architecture decisions backed by primary-source research from three subagent recons. Backlog items (CPU-only, no GPU budget): - Spike 006 — real HF model smoke (Wave 7 next) - Spike 007 — real trace ingestion (Wave 8) - Spike 008 — Streaming DiLoCo smoke (Wave 9) - Wave 10 — packaging (pyproject.toml + examples/) - Spike 002a-mini — Modal-gated GPU smoke (Phase 10) Research (docs/research/, 1168 lines total): - MODAL_RECONNAISSANCE.md — Modal pricing + setup, primary-sourced from modal.com/pricing and modal.com/docs. Verdict: Modal L4 is $0.08-0.13 per smoke run but loses to local 5090 by 10x on iteration cycle (3-5min vs 25-40s). Modal becomes correct for parallel sweeps, 7B+ models, multi-node training, or CI repro — none of which apply to gap-closer wave. - DILOCO_RECONNAISSANCE.md — audited 5 candidates. meta-pytorch/torchft wins: BSD-3, 312 com…ac4bfb4 -

baladithyabSelf-audit of whether the framework actually encapsulates the original brief.

Wave 3: integration architecture + spike-005 trainer skeleton (16 tests pass)
baladithyabUser asked: can RLVR + Composer-SDPO + N-teacher-replay all integrate complementarily with the PyTorch agentic-RL stack (Monarch / TorchForge / OpenEnv / VeRL / TRL)? Answer (verified, not extrapolated): YES, with concrete extension points: 1. Verified ground-truth integration surfaces via DeepWiki audits: - TRL: subclass GRPOTrainer, override _compute_loss(model, inputs); plug OpenEnv via environment_factory= kwarg. - VeRL: register a new advantage estimator via @register_adv_est(name); attach extra fields to DataProto.batch / non_tensor_batch (precedent exists — distillation already uses 'teacher_log_probs' the same way). - OPSD: generalized_jsd_loss is a self-contained static method, MIT, directly liftable. FlashAttention-2 compatible, standard PyTorch. 2.

Integrate Cursor blog directly + audit research note + add SDPO/OPSD link
baladithyabUser flagged a real gap: I had dispatched a subagent to research Composer 2.5 but never personally read the Cursor blog. Audit findings: 1. The targeted-textual-feedback method = published SDPO (Hubotter et al., arXiv:2601.20802, ICLR 2026 Workshop) + OPSD (Zhao et al., arXiv:2601.18734, code at github.com/siyan-zhao/OPSD, MIT). Cursor cites these directly in footnote 1 of the blog. The subagent's research note never mentioned them. This is huge: there's published, MIT-licensed code for Composer's secret sauce. 2. Several claims in research/01-composer-2.5.md are NOT in the Cursor blog and were extrapolated from secondary sources ("85% post-training compute", "Anyrun" environment name, specific benchmark scores, "PPO or GRPO variant"). Likely correct via community consensus but not blog-verified. 3. Composer hint-distill (single model, hint-conditioned context) and trace-replay-distill (N external teachers) are TWO genuinely different mechanisms, not compe…1cede23 -
