Phase 4 of substrate-unified-registry: turn on the existing
kei-model-router by changing manifest defaults from `model = "opus"`
to `model = "sonnet"` for routine agents, and give every git branch
a deterministic DNA in the kei-status dashboard.
The model-tier system was BUILT (`_primitives/_rust/kei-model-router/`
crate with Beta posterior, complexity τ-estimator, escalate ladder,
calibrate subcommand) and the advisor hook
(`~/.claude/hooks/model-router-advisor.sh`) was REGISTERED. But every
ledger row from this session ran on Opus because:
1. All 38 manifests hard-coded `model = "opus"` → no chance for the
router to recommend cheaper.
2. The orchestrator (me) ignored the stderr advisory.
This commit closes (1). (2) is a behavioural change tracked separately.
Manifest reclassification (4 Opus + 34 Sonnet):
Opus (hard reasoning):
- architect (system-design synthesis)
- ml-implementer (Math-First paradigm)
- ml-researcher (literature analysis)
- security-auditor (deep risk synthesis)
Sonnet (everything else):
- 8 code-implementer-* + code-implementer
- 5 critic-* + critic
- 6 infra-implementer-* + infra-implementer
- 4 researcher-* + researcher
- 6 validator-* + validator
- 3 security-auditor-{differential,supply-chain,variant}
- cost-guardian, fal-ai-runner, frontend-validator, modal-runner
Regenerated all 38 `_generated/*.md` so the YAML frontmatter `model:`
field matches the manifest.
Branch DNA (kei-registry status):
- New `compute_branch_dna(name, commit_sha)` in `status.rs`. Format
`branch:
:<sha8(name)>::<sha8(commit)>`, mirrors kei-shared
DNA wire layout `<role>::<caps>::<scope_sha8>::<body_sha8>`.
- Deterministic — same `(name, commit)` → same DNA. Changes when
either changes. No DB persistence: the underlying truth lives in
`.git/refs/heads/<name>`.
- 3 new unit tests cover format, determinism, name-change, commit-
change. `cargo test status::tests` → 10 passed.
`kei-registry status` output now shows DNA prefix per branch alongside
ahead/behind, last commit. Combined with existing per-block DNA in the
[Blocks] and [Path Atoms] sections + `dna` column on `agents` table in
kei-ledger, every artefact in the dashboard has an identifier:
Atoms (incl path-atoms) → atom::<caps>::<scope>::<body> (registry)
Skills/Rules/Hooks/Prim → <role>::<caps>::<scope>::<body> (registry)
Agent forks → row.dna in agents table (ledger)
Local branches → branch:
:<sha8>::<sha8> (computed)
What this does NOT do:
- No outcome backfill — the 205 NULL outcomes in ledger still prevent
the Beta posterior from learning. Router falls back to top-tier
until ≥1 datapoint per (task_class, model) accumulates. Tracked as
follow-up.
- No post-checkout hook to auto-register branches in kei-ledger. Live
shell-out to `git for-each-ref` is fast enough for the dashboard;
persistence buys nothing the .git tree doesn't already give.
=== STATUS-TRUTH MARKER ===
shipped: functional
stubs: 0
cargo-check: PASS
behaviour-verified: yes
follow-up-required:
- Outcome backfill hook (writes outcome to ledger after agent done)
- User /model claude-sonnet-4-6 for current session (5x cheaper)
- Push the orchestrator (me) to read advisor stderr in real-time

$98.78 Modal Incident (2026-02-26): promised $27, spent $98.78 in one session. Prices guessed not \

anti-stop guard Incident (2026-03-29): stopped a 1.4-hour training run for a non-critical bug. Cost: \

1.4 hours A10G + restart + re-warmup. Every kill rule exists because of that day.
