# Project State & Remaining Work — composer-replication-framework

**Snapshot date:** 2026-06-09
**Framework HEAD:** `aae66fa` (ADR-014 PO-objective menu) + `8d2e6fc` (seeds sync)
**LMA consumer HEAD:** `37c0ea5` (DAPO-vs-Dr.GRPO washout) on `Codeseys/llm-mental-alterations`

This doc is the single-page "where things stand" record. Issue tracking is git-native
via [Seeds](https://github.com/jayminwest/seeds) (`sd` CLI) in `.seeds/`. Run `sd ready`
for unblocked work, `sd list` for everything, `sd show <id>` for detail.

## What this framework is (honest one-paragraph)

A reusable RL/data-gen framework that replicates Cursor's **Composer 2.5** post-training
recipe at small scale, whose north-star consumer is the **llm-mental-alterations (LMA)**
project (apply targeted RL to a personality-altered SFT model and measure washout vs
amplification). Past-skeleton, production-shaped: 8 subpackages, 266 tests pass / 62 skip (measured 2026-06-09; see docs/V1_V8_COVERAGE.md for the canonical count + why skips vary by env),
installable, with worked GSM8K-GRPO + SDPO-real-trace + A1-8B examples.

## The 3-channel loss — with HONEST provenance

`grpo + alpha_sdpo·sdpo_kl + beta_replay·trace_replay_dpo`

| Channel | What | Composer provenance |
|---|---|---|
| **1 — base PO objective** | Selectable MENU (ADR-014): `loss_type ∈ {grpo, dr_grpo, bnpo, dapo, cispo, luspo, sapo, vespo}`, default **Dr.GRPO** | ✅ CONFIRMED — Composer's base is Dr.GRPO (k1 KL; TRL uses k3, documented delta) |
| **2 — SDPO/OPSD** | On-policy self-distillation vs hint-conditioned teacher | ✅ CONFIRMED — IS Composer 2.5's "targeted RL with textual feedback" |
| **3 — trace-replay-DPO** | Preference DPO vs frontier teachers | ⚠️ **FRAMEWORK'S OWN ADDITIVE CHANNEL — NOT Composer.** Primary sources (blog + arXiv:2603.24477 §4.1) have no DPO / preference-pairs / multi-teacher. It's a deliberate β-gated research probe in the A0→A4 ladder. The code is fine; only the "this replicates Composer" framing was ever wrong, and ADR-014 records the correction. |

## What's PROVEN (don't re-litigate)

- **CPU SDPO fires** through the real collator alignment indices (JSD 0.057, gradient flows).
- **A10G GPU train-proof**: Qwen2.5-0.5B, bf16, 30 steps, loss 4.73→0.005 monotone.
- **A1 8B run EXECUTED**: 200 steps GRPO-only on `wave-h-5-llama-31-8b-seed42`, A100, reward
  0.331→0.751, KL≈0.0014. Alteration eval at N=895.
- **DAPO-vs-Dr.GRPO washout** (A1): washout is **objective-INVARIANT at lr=1e-6** because DAPO's
  clip-higher (`clip_ratio/high_mean`) never engaged (=0 across all 200 steps). We measured
  "DAPO that couldn't fire its difference," not a real objective comparison.
- **nanochat post-training arc** (separate Modal laydown): SFT ChatCORE 0.3076, GSM8K-GRPO
  Pass@1 doubled 0.0525→0.1250, SDPO end-to-end train smoke PASS.
- **832/832 real-trace SDPO alignment** (Wave 21) with `strip_thinking=False`.

## Remaining work (filed as Seeds — `sd ready` / `sd show <id>`)

### Ready / unblocked
- **`…-cb74` (P1 security):** ROTATE the exposed HF write-token `hf_uRP…`. On-disk plaintext
  scrubbed 2026-05-29; token itself never rotated → treat as compromised. **User-only.**
- **`…-211e` (P2):** Higher-lr PO-objective sweep — make DAPO/GSPO clip-higher actually fire.
  The informative experiment the washout null pointed to. Likely *more* informative than the
  A2-A4 ladder at lr=1e-6 (same inert-knob risk). GPU + budget-gated.
- **`…-4936` (P2):** A2 SDPO-only ladder arm — build the runner + error-trace dataset. The
  big build: `modal_ladder_a1.py` is hardcoded to A1; `train_grpo.py` is a plan-builder with a
  placeholder pip name. Needs a real SDPO dataset (`strip_thinking=False`, seq≥1536) + an A100
  entrypoint off the proven A1 image. GPU + budget-gated.
- **`…-245d` (P4):** Docker substrate e2e — test exists + skips cleanly; hardware-blocked (no
  Docker host). Run the 4 gates against a real container when a Docker host exists.

### Blocked (dependency-gated)
- **`…-42f5` (P3):** A3 replay-DPO-only arm — needs a trace-replay-DPO preference corpus.
  Blocked on A2 (shared runner/infra). Framework's-own-channel washout probe.
- **`…-dd7b` (P3):** A4 combined arm + final A0–A4 comparison table. Blocked on A2 **and** A3
  (its value is reading the combined effect against the isolated baselines).

## Branch convention (canonical: `main`)

**`main` is the canonical branch on both HF repos** (decided 2026-06-09). As of that date
`main == master == fb13ea3` (framework) / `37c0ea5` (LMA) — converged via clean fast-forward.
**Push to `main`** (or to both in lockstep). `master` is retained only as a mirror; do not let
the two drift. A fresh `git clone` now defaults to `main` and gets the complete tree (incl.
`make_dr_grpo_config` + ADR-014), so the old "must checkout master" foot-gun is RETIRED as long
as `main` stays current.

## Load-bearing gotchas (carry these forward)

1. **Branch sync (RESOLVED 2026-06-09, keep it that way).** `main` previously LAGGED `master`
   (frozen at Wave 19), which is why older Modal images pin a `master` SHA "because main predates
   `make_dr_grpo_config`." That divergence is now fixed (`main == master`). **Keep pushing to
   `main`** so it never lags again; the SHA pins in Modal images remain correct but their
   "main is stale" rationale no longer applies once both branches stay in sync.
2. **SDPO on real agent traces requires `strip_thinking=False`** — ~67% of error-recovery
   turns are pure thinking; stripping yields empty masks. Keep `max_seq_len ≥ 1536`.
3. **OUTPUT_DIR clobber:** any sweep dimension (objective/lr/seed) you'll compare side-by-side
   MUST be in the output path, or the later run overwrites the earlier checkpoint.
4. **Size Modal timeout off the SLOWEST objective** (DAPO overlong-mask ~26s/it, not Dr.GRPO ~17s/it).
5. **Log the distinguishing diagnostic** for any PO-objective ablation (`clip_ratio/high_mean`
   for DAPO, sequence-level ratio for GSPO). A 0 means "knob didn't engage," NOT "objectives equal."

## In-flight as of this snapshot

- A `docs/refine-2026-06` branch (ccode-ultracode lane) is refining the `docs/` corpus:
  propagating the Channel-3 provenance correction + ADR-014 menu into stale docs, archiving
  dated `WAVE_*_FINAL_REVIEW` artifacts, refreshing README/BACKLOG. Docs-only; human review
  before merge.

## Pointers

- Canonical wiki hub: `~/wiki/projects/composer-replication-framework.md`
- ADRs: `docs/adrs/` (001–014); ADR-014 is newest + records the Channel-3 provenance decision.
- LMA consumer + A1 results: `Codeseys/llm-mental-alterations` → `composer_replication_runs/`.
