What is arcanea-canon?

A command for maintaining the official story-world rules of Arcanea, including its characters, archetypes, frequencies, realms, and vocabulary. Each change records the applicable non-commercial licence.

Use it to add, revise, version, or pin Arcanea canon changes.

It keeps later work aligned with one approved version of the fictional world and makes reuse terms explicit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00067	$0.01631
Opus 5	$0.00034	$0.00816
Sonnet 5	$0.00013	$0.00326
Haiku 4.5	$0.00007	$0.00163

Security

Grade A, and why

arcanea-canon scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/arcanea-canon

Load SIP.md, VERTICALS.md (Arcanea entry), VOICES.md, ATTESTATIONS.md, and Arcanea's own canon source of truth (C:\Users\frank\Arcanea\.arcanea\lore\CANON_LOCKED.md and C:\Users\frank\Arcanea\ARCANEA_UNIVERSE_CANON.md). Manage Arcanea canon with SIP attestation discipline.

Input

$ARGUMENTS

Sovereignty posture

Arcanea is a canon-defining vertical (per SIP § Layer 6) — its archetype set (Guardians, Vel'Tara, Hz frequencies, realm/essence vocabulary) is the first canon layer that downstream verticals may compose with. This command executes inside Arcanea's sovereign domain; other verticals consume canon through attestation + license, not by running this command.

License: CC-BY-NC 4.0 · © Arcanea BV. Every emission pins the license. Commercial reuse requires separate agreement with Arcanea BV.

Actions

`bump <version>`

Bump canon SemVer. Breaking changes (archetype rename, frequency reassignment, archetype removal) require a major bump. Additions (new Guardian, new realm) minor. Clarifications/errata patch.

Process:

Validate SemVer follows current canon version pinned in Arcanea repo (CANON.md header or ARCANEA_UNIVERSE_CANON.md).
Classify the bump (major/minor/patch) against SIP § Versioning rules.
If major, require a 90-day deprecation window for downstream adopters per SIP Layer 2 pinning rules. Generate deprecation notice.
Update canon version in source files.
Emit /sip-attest block for the bump — composition layers invoked, canon version pinned, nodes (always Frank as canon-keeper + Guardians cast as performance voices).
Append entry to ATTESTATIONS.md under new version heading.

`add <archetype> to <layer>`

Add new archetype to a canonical layer. Layers: guardians, veltara, hz, realms, essences, sparks.

Process:

Validate the archetype name is not already in use (collision halts).
Validate the proposed archetype has: name, one-sentence essence, placement in layer hierarchy, interaction rules with existing archetypes.
Declare the archetype's canon-keeper (typically Frank).
Run through /luminor-board "canon addition: <archetype>" for pressure-test (Draconis + Lyssandria + Elara vectors matter most for canon).
If board returns PROCEED or REVISE-applied, write archetype to canon source.
Emit /sip-attest block. Attestation pins canon version that includes the new archetype.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
