From 486940cbe473c573dedb18d3b099d5e072d18899 Mon Sep 17 00:00:00 2001 From: Bill Date: Sun, 19 Apr 2026 13:46:08 -0600 Subject: [PATCH] Specialist fleet handoff 2026-04-19 + remaining eval artifacts Handoff covers: automatability SOLVED (2-stage, 100%), worker_type 92.2% (combined dataset), verification_type 84.3% (more data needed), prereq_op blocked on taskitem schema gap. Next: worker_type implementer data gen, verification_type combined dataset, prereq_op deferred to Sprint 004.

Note: those baselines used different (smaller) datasets and +are not directly comparable — the sweep is now on a clean unified pipeline. + +--- + +## What Was Done + +### 1. Full pilot sweep (sweep_all_gates.sh --pilot-only) + +All 4 gates, small_plus + medium tiers, 3000 steps each. +Results: `specialists/eval/results/*_sweep.json` + +Key finding: medium tier did not improve over small_plus for any gate. +Capacity is not the bottleneck anywhere in the fleet. + +### 2. Automatability — 2-stage decomposition (SOLVED) + +Root cause: Directional Collapse (Pattern #1 in `whetstone_RSA/docs/diagnostic_patterns.md`). +`deterministic` was mapping 100% of errors to `template` — the two classes are +indistinguishable in taskitem title text. Adding data or scaling both fail. + +Fix: 2-stage pipeline: +- Stage 1 binary: `low_entropy {deterministic, template}` vs `needs_routing {specialist, slm, llm, human}` +- Stage 2 4-way: `specialist / slm / llm / human` + +Results: Stage 1 = 100%, Stage 2 = 100%, combined 5-way = 100%. + +Script: `specialists/scripts/split_automatability_decompose.py` +Split TSVs: `specialists/data/generated/automatability_binary_*.tsv`, `automatability_routed_*.tsv` +Result: `specialists/eval/results/automatability_decompose.json` + +Note on `low_entropy` bucket: `deterministic` vs `template` is NOT distinguishable +from taskitem titles alone — that boundary requires features not in the current +input schema (how a task is implemented, not what it builds). If the downstream +system ever needs to distinguish them, the fix is Upstream Feature Starvation +(Pattern #6): enrich the taskitem schema, not the model. + +### 3. Worker_type — combined dataset + +Previous train: 300 examples (sprint plan titles only). +Added: `worker_type_projects_train.tsv` (361 examples, `title | intent` format). +Combined: 661 train / 115 eval. + +Results: 80.8% → 92.2% overall. `implementer` 42.9% → 75.0%. +`reviewer` and `architect` are now perfect (100%). + +Combined TSVs: `specialists/data/generated/worker_type_combined_*.tsv` +Result: `specialists/eval/results/worker_type_combined_sweep.json` + +Remaining `implementer` confusion is Label Boundary Drift (Pattern #10): +the heuristic keyword classifier labels "implementer" by keyword absence (default), +producing noisy boundaries on ambiguous titles. The short-text format limits how +much a model can learn without richer features. + +### 4. Diagnostic patterns document + +`whetstone_RSA/docs/diagnostic_patterns.md` — committed to whetstone_RSA. +10 named patterns covering the most common gate failure modes, each with: +observable signal, mechanism, detection test, specific fix, failure conditions, +real example from this project. + +Written at a level usable by developers and smaller models without deep ML +background. Motivated by the question: how small a model / how junior a developer +does it take to apply the insight that solved automatability? + +--- + +## What Is NOT Done — Next Session + +### Priority 1: worker_type implementer improvement + +Option A (recommended): Generate more data with explicit construction-verb examples. +The current data labels "implementer" by keyword absence — it's the default. Add +synthetic examples with clear implementer signals: "Implement X", "Build X", "Write X". + +Option B: Human relabeling of the 52 eval examples. If reviewers consistently +disagree on >30% of errors, apply Label Boundary Drift fix (rewrite label criteria). + +Target: get `implementer` above 85% before declaring worker_type deployable. + +### Priority 2: verification_type — more data + +Currently 83.7% (small_plus), 84.3% (medium). Capacity plateau confirmed. +Confusion concentrates in `unit`↔`integration`↔`schema` — semantically adjacent. +These have the projects equivalent: `verification_type_projects_train.tsv` (unused). +Try the same combined-dataset approach that worked for worker_type. + +### Priority 3: prereq_op — blocked, do not pursue until schema change + +Root cause: Upstream Feature Starvation (Pattern #6). The taskitem schema does not +carry discriminative fields at inference time. No amount of data or model work +fixes this. See `whetstone_RSA/docs/diagnostic_patterns.md` Pattern #6. + +Next action is in whetstone_DSL Sprint 004 (pipeline decision audit), not here. + +### Not on the list + +- automatability: SOLVED,
