colophon (n.): the closing imprint that names a manuscript's author, reviewers, and authority.
Build fast. Ship authorized.
Three humans direct a bench of ~100 trained AI specialists. Accelera Solutions and its SigilArk affiliate deliver federal systems with their RMF evidence. Humans decide, the bench ships, authorization accumulates from day one.

I · The problem and the inversion
From day last to day one
Federal programs need dozens of specialties to ship under ATO. Compliance evidence is reconstructed at the end. Timelines slip, attrition restarts the clock.
Colophon inverts that order. Three humans direct ~100 trained AI specialists; the Stationarius chain-of-custody protocol emits the RMF artifact set as structural byproduct of each shipped increment.
A qualitative line chart comparing the shape of compliance effort across a delivery timeline. Horizontal axis runs through five phases: Day 1, Delivery, Release, ATO submission, AO signs. The traditional curve stays near-zero through delivery and spikes sharply at ATO submission, representing reconstructive compliance work performed by dedicated FTEs at the end. The Colophon curve sits at a moderate plateau through delivery and does not spike at ATO submission, because the authorization evidence package has already accumulated. Both curves return to near-zero after the Authorizing Official signs. The point is the shape difference, not the magnitude.
Traditional · reconstructive compliance Colophon · chain-stamped continuously
A horizontal pipeline showing how work moves through the Colophon chain of custody. Stages from left to right: requirements, trace review, architecture decisions (optional branch shown above the main path), decomposition into work units, implementation with attached test evidence, the review gauntlet with four parallel review lenses (code, adversarial, test quality, security), and release. Each transition between stages is a structural gate enforced by the chain, not convention. The implementer can refuse to start work whose upstream is not ready, and the refusal is the protection. Below the pipeline, a separate row shows cross-cutting specialists (Documentation, Data architect, Build-deployer, and RCA engineer) that apply across multiple stages rather than occupying a fixed handoff position.

II · The bench
The bench
Specialist agents fill specialist roles. Every artifact an IL4/5/6 program needs, emitted as structural byproduct. Humans direct the work; the bench ships it with its evidence.

Two-column diagram. Left column lists six typed artifacts the Colophon chain-of-custody protocol emits: requirement traces, architecture decisions, pecia with attached test evidence, review-lens sign-offs, release records, and incident root-cause analyses. Right column lists five Risk Management Framework (NIST 800-37 Rev 2) artifact classes: System Security Plan, Security Assessment Report, Plan of Action and Milestones, Authorization Package, and Continuous Monitoring. Connecting lines show which protocol artifacts primarily feed which RMF artifacts. The mapping is many-to-many in practice; the diagram shows primary relationships only.

Change Control Board and role mapping
Change Control Board
Technical
Decides architecture and engineering direction: target-platform tradeoffs, system boundaries, tooling selection, build-vs-buy calls.
Program
Decides scope and delivery: cadence, stakeholder coordination, what ships next, what defers, where the bench focuses.
ATO / Cyber
Decides authorization posture: compliance path, AO-facing evidence, security gate enforcement, risk acceptance.

A three-tier diagram. Bottom tier: six peer specialist agents (Planner, Architect, Implementer, Reviewer, Adversarial, SAST) with bidirectional arcs showing peer-to-peer conflict resolution. Middle tier: three arbiter agents, activated by three trigger conditions (flag raised, audit sample, or peers exhausted). Top tier: the Change Control Board, a single node labeled "Change Control Board" with subtitle "handlers convene," where human handlers (Technical, Program, ATO/Cyber) convene when arbiters cannot resolve. The CCB is human-side; it does not contain agents of its own. Visual asymmetry: peer tier is wide and prominent, arbiter tier is narrower, CCB tier is a single node with a focal ripple animation.

Stationarius: the coordination protocol
Stationarius routes work between agents and humans over Colloquy (typed wire protocol, five message classes) and writes every exchange to Decretum, the audit-trailed decision precedent store the AO reads at authorization.
Peer-to-peer
Specialist agents resolve most work themselves. Every implementation passes a five-lens review chain (code review, adversarial review, test quality, security, and CI parity) with signed concerns. A sixth lens (accessibility) gates user-facing changes. Async + multi-threaded autonomy.
Arbiter agents
When revisions on a single work unit exceed a configured threshold, an arbiter agent auto-activates, diagnoses the impasse, and writes a structured verdict prescribing the next step. Verdicts are advisory by default; high-stakes work flips them binding by frontmatter declaration.
Change Control Board
The CCB convenes only when arbiters can't resolve, or when a change is production-impacting, cross-cutting, or compliance-domain by class. Role-dependent veto applies; each seat decides binding within its named domain.
Three-column architecture diagram. Left column: five specialist agents (Planner, Implementer, Reviewer, Adversarial, SAST) dispatching work into the central engine. Center column: Stationarius shown as a stacked panel of four named sub-components (Routing Rules, Agent Registry, Decretum decision-precedent store, and Colloquy typed wire protocol) which together orchestrate the three-tier escalation flow. Right column: the handler triad (Technical, Program, ATO/Cyber) receiving escalations from Stationarius. Three communication channels are labeled at the bottom: Channel A is the pull-driven MCP tool surface that agents call into, Channel B is the MCP subscription surface that returns verdicts back to originating sessions, Channel C is the outbound push surface that wakes handlers via Slack, APNs, FCM, or email.
Async + multi-threaded by design. Three to five agents work in parallel under one human's direction, instructing each other inside the protocol. Humans serve as the CCB for actions and decisions, not as prompt-by-prompt operators.
One bench. Four providers. Sovereign by design. Routes per task across Anthropic, OpenAI, Gemini, and Llama 4 via cloud providers or local / air-gapped hardware (Ollama, vLLM). Selection driven by sovereignty, cost, and classification.
A timeline diagram split into two waves of work. Wave 1 shows three subagents working concurrently: an Implementer, an Adversarial Reviewer, and a Test-Quality Reviewer. Each is drawn as a horizontal stripe along the time axis, with offset start times and overlapping durations to communicate parallelism. Between Wave 1 and Wave 2 sits a Stationarius consolidation row showing the engine collecting subagent outputs and dispatching the next wave. Wave 2 shows an Implementer revision pass responding to the consolidated verdicts. A footer annotation cites a real example: colophon-platform PR #182 (Quaestor workflow canonicalization) used three parallel subagents in one wave to produce 914 lines across 19 files.
