ROADMAP

Structural regime measurement on Ethereum, Polygon, Solana and Avalanche: infrastructure structure × economic demand, four regimes (S1D1 · S1D2 · S2D1 · S2D2), one signed vector per chain. ETH and POL validated; SOL and AVAX in calibration.

Structural measurement extended to Arbitrum, Base and Optimism (sequencer response, blob saturation). Cross-chain Execution Context API live: L1 × L2 × Bridge → certified on-chain context. Python SDK (pip install invarians), labs.invarians.com and agentic.invarians.com (CRE reference integration) launched.

L2 threshold calibration completed on a 30-day production baseline (Arbitrum, Base, Optimism; rhythm, continuity, sequencer_publish_latency), coherent with L1 FPR. Bridge scope opened to variable-latency surfaces (Circle CCTP, Chainlink CCIP) at per-message depth. Agentic pressure baseline collecting since 2026-03-30 — not reconstructable retroactively.

Execution context exposed as one panel. A single direction-agnostic call, GET /v2/panel, returns L1, L2 and bridge states; the agent composes the route it cares about. Invarians exposes states, not directions — each bridge entry carries a unified BS1 / BS2 (or null).

Full EVM centralised coverage: seven chains, 20 variable-latency lanes in one panel (10 Circle CCTP + 10 Chainlink CCIP), unified BS1 / BS2 on panel.bridges[].state. Each entry carries its own calibrated flag and capability_level, so agents reason about raw vs calibrated at a glance. One call: GET /v2/panel.

API restructured around three signed primitives in one payload: Attestation (HMAC-SHA256 envelope), Regime (12 SxDx codes per chain via the structural × demand grid), Delta (per-metric drift over short ~10h and long ~30d EMAs). New endpoints GET /v2/panel + POST /v2/verify, tiered via ?include=. SDK 0.7.0.

CCTP V1 upgraded from health-probe proxy to per-message attestation: each USDC transfer captured with its Circle ECDSA signature, independently verifiable against Circle's attester key. Confidence LOW → MEDIUM on 10 EVM routes. SDK 0.8.0. Retired 2026-05-27 in favour of CCTP V2 (corpus preserved read-only).

CCIP lanes upgraded from aggregate signals to per-message capture: source and destination matched by bytes32 messageId, real send-to-execute latency per lane per direction. Reaches per_message_attested; crypto.anchor stays null until DON multi-sig capture (next step). SDK 0.9.0.

Full migration to CCTP V2 ahead of Circle's V1 sunset (2026-07-31), across 10 ETH-paired routes. Standard mode (finality-bound, ~13-30 min) is the panel default for the RWA audience; Fast is subordinated in observed_fast_mode. New nonce retrieval key, plus a confounded_by_iris_downtime flag that breaks the "BS2 because my sensor is down" tautology. The planned latency cold-start was superseded on 2026-06-01 by event-based structural classification (BRIDGE_STATE_STRUCTURAL_v1.2); CCTP V2 routes are now live BS1/BS2. SDK 0.11.0.

Bridge state moves from a statistical threshold to a structural reading of corridor invariants: BS1 / BS2 now answer "are the corridor's invariants holding", not "is latency above a percentile". Adds stuck-message detection on CCTP Standard (invariant I5, 48 h cap, mechanically derived). Methodology v1.2 signed and anchored.

A Chainlink CRE workflow reads the signed Invarians bridge state and emits an execution verdict — ACT / DEFER / WAIT_FOR_DATA — inside the real CRE runtime. Validated on a single node; multi-node DON consensus is the next step. The consumer pattern (DON fetches the Invarians attestation over signed HTTPS) is the path toward Phase 02.

Delta calibration shown to be chain-type-exclusive (ETH-ARB and ETH-OP corpora, 648-config grid, Benjamini-Hochberg FDR: disjoint precursor sets that don't transfer). The composite drift block is replaced by an explicit per-chain precursors[] array carrying full calibration metadata. Method and three independent tests in the research note: Delta calibration is chain-type-exclusive, 2025.

Crypto-grounding of CCIP: capture the F+1 threshold-signed DON multi-sig on CommitReport (per batch, with per-message Merkle inclusion proofs). capability_level moves per_message_attested → per_message_crypto_anchored, crypto.anchor: "don_threshold_sig". Dual-purpose: the same DON mechanism is what hosts the Invarians attestation in Phase 02.

A Model Context Protocol server exposing Invarians execution context as a native agent tool — an agent on Claude, GPT or CRE calls get_panel_v2() as a first-class capability, no SDK middleware. SDK addresses developers; MCP addresses agents directly.

CCTP confidence moving MEDIUM → HIGH as the 30-day clean window accumulates (target ~2026-06-10); Tier 2 routes (AVAX↔ARB, BASE↔OP) added on sufficient throughput. ETH↔SOL CCIP under passive observation (thinner Solana history, RPC-pipeline dependency) toward Q1 2027.

Solana and Avalanche structural calibration validated, bringing regime classification to full confidence on all four L1s. The signed 12-code grid (live on ETH, POL, BASE, OP since 2026-04-29) generalised to every chain via event-based backtest on documented incidents. Coverage extended to third-party bridges (LayerZero, Across). Pattern Reference enters production: historical frequencies per directional tuple across 7 chains.

A Chainlink Functions layer enables DON-level computation: each node fetches structural metrics from its own RPC endpoint and reaches consensus on the regime vector, with no single computation source. The hybrid model runs both paths at once — API for agents, DON consensus for smart contracts — and CRE workflows extend to mainnet with the full L1 × L2 × Bridge gate. This moves runtime trust from a single operator to a DON; capturing CCIP commit reports in Phase 01 was the operational reference for the transition.

CCIP observability (at per_message_crypto_anchored since Phase 01) wired into the A2A coordination layer: a cursed CCIP lane freezes routing independently of statistical classification, invisible to any fee monitor. This unlocks a unified composite context — L1×L1 (SxDx × SxDx × BSx_CCIP) and L1×L2 — passed as a signed panel from Agent A to Agent B before any cross-chain action, same verifiable ground truth, no trust required between them. EVM lanes ready at launch; ETH↔SOL completes Q1 2027.

Invarians publishes structural baselines each cycle; independent staked nodes compute their own invariants from raw RPC data and submit regime classifications, earning rewards when their output matches consensus (each node signing with a registered Ed25519 key). Invarians keeps the methodology, baseline and reference-publisher role — but computation, and with it trust, becomes distributed. Calibration stops being a private asset and becomes a public good, reproducible and verifiable by any participant.
