The phase arc
One phase at a time, each behind an exit gate with a number on it. We are late to tier 1 and early to tier 0 — where the field ships eviction alone and no major harness sends a diff.
Foundations
tier — · shipped · done“Nothing above this is worth building on sand.”
- Core schemas and the closed Expect DSL — Zod first, types derived
- Lossless crash-safe recorder: append-only, fsync per event, blobs over 64KB content-addressed
- Verified replay executor — deterministic steps at zero LLM tokens, every expect re-checked
- The sacred invariant suite touching every executor exit path
Working memory — tier 0
tier 0 · launched 2026-08-08 · done“The first browser agent with a managed context window.”
- A11 observation eviction — kills the dominant quadratic term
- A4 diff observations — 849 diffs in G1, median 24 chars, −99.6% vs re-send
- B3 cache-layout discipline — immutable prefix routed through prompt_cache_key, 20.5% cost cut at WP-N25
- Launch package: the npx quickstart, the README number, the demo
Cumulative logical input must grow materially slower with task length — a public ≥30% floor, CI-bounded, at success parity.
A tokens-per-task win at success parity — at least 15 runs, seeded-bootstrap lower bound above the floor.
The harness that learns — tiers 1 & 2
tier 1 · 2 · 2026 Q4 · ← we are here“Your 50th task on a site costs a fraction of your 1st.”
- Playbook distiller — trajectories become verified playbooks
- Matcher: semantic match + bind behind the fingerprint gate
- B4, identity v2, and synthetic nested frame/open-shadow contexts are built; authoritative evidence is next
Speculation
tier 2 · 2027 Q1“Warm flows bounded by think-time only.”
- Transition models learned from recorded runs
- Speculative pre-execution with assertion-gated commits
Fleet & enterprise
tier — · 2027 Q2–Q3“10K tasks a day, audited, lowest $ per task.”
- Fleet-scale memory administration and audit surfaces
- Every replay attributable: who, when, from which verified run
Platform
tier — · 2027 Q4+“The efficiency substrate other agents build on.”
- The memory manager as a surface other harnesses consume
Built and working end-to-end
- ✓Core schemas + the closed Expect DSL (10 primitives)
- ✓Lossless, crash-safe recorder
- ✓Verified replay executor — zero-LLM deterministic steps
- ✓CDP browser backend + fake-world fixture backends
- ✓Perception: distill → stable IDs → budget → diffs
- ✓A11 observation eviction
- ✓A4 diff observations, measured on real pages
- ✓B3 cache-layout discipline, economically qualified (T11)
- ✓B4 deterministic action-history compaction (long-run qualification pending)
- ✓Agent loop with tagged LLM accounting on every call
- ✓Benchmark matrix, curve reports, head-to-head launch gate
- ✓Action plane: settledness, self-healing resolution, scoped repair
Not built — on purpose, on the record
The roadmap rule is executor before distiller — never build ahead of the phase. The gaps are part of the ledger:
B4 long-run qualification
the mechanism is built; 50+ step provider cache economics and SPA parity remain E7.6
Playbook distiller
V1 replays hand-written playbooks; trajectory → playbook distillation is unbuilt
Matcher (semantic match + bind)
only the exact-fingerprint hard gate exists today
Site memory, model routing, speculation
designed in docs/02, scheduled for P2/P3
P1 launch closure
G1 and corrected G2 pass. Public @rotehq/cli@0.1.0 matches its audited registry artifact, and T28 verifies the provider-backed quickstart from an empty directory. P1 launched without expanding its one-provider, pinned-cell claims. E7.1's corpus, identity v2, and T31 synthetic composed contexts are built; authoritative evidence is next, with structural action-contract drift still the cross-cutting P2 priority.
