Plant EPRFS Command
Plant ONE runtime-authored slash command in its elohim-native CommandPackage: the package under .epr-meta/elohim/packages/commands/ becomes authoritative, while .claude/commands/X.md and .codex/commands/X.md remain byte-identical generated projections. This is the command member of the plant-eprfs family. Use elohim-package-authoring for the shared package-first discipline.
Plant one command, prove it, then the next.
Why the command flip is verbatim
A command is a flat markdown prompt with optional frontmatter, not a skill-style runtime dialect. Its package stores the entire file in source.body. projectCommand returns that string unchanged for both runtimes. Planting therefore moves authority without reformatting frontmatter, rewriting $ARGUMENTS, or localizing runtime-specific prose.
Before planting, the fidelity gate proves project(import(source)) === source byte-for-byte. After planting, it proves project(package) === .claude command === .codex command. The command cannot carry a reliable inline authority marker because many commands have no frontmatter, so the importer reads authority from the existing package and skips any metadata.master: "package" command.
Procedure (one command X)
- Run
node elohim/sdk/domains/elohim-agent/scripts/package-projections.mjs verify. Confirm CommandPackage:X is source-fidelity and its Claude source round-trips byte-for-byte. If the package does not exist, run the normal command import first.
- Snapshot the two command projections with
sha256sum .claude/commands/X.md .codex/commands/X.md.
- Edit
.epr-meta/elohim/packages/commands/X.json only. Preserve metadata.sourceRuntime; add metadata.master: "package" and metadata.composedBy: "<your model id>". Ensure metadata.governance carries eprRef: epr:elohim-agent/commands/X, policy: capability-governance@1, gates epr-meta-resolver and elohim-agent:packages:verify, and ledger .claude/data/governance-findings.jsonl. Do not edit source.body.
- Regenerate only the target:
node elohim/sdk/domains/elohim-agent/scripts/package-projections.mjs project --write-fixtures --write-runtime --only CommandPackage:X.
- Re-run the hashes. Both runtime files and both projection fixtures must be byte-identical to
source.body; any content diff is a STOP condition.
- Run
node elohim/sdk/domains/elohim-agent/scripts/package-projections.mjs verify. CommandPackage:X must now report package-first and must not require a re-importable Claude source.
- Record composition with
eprfs-agent compose-graph .epr-meta/elohim/packages --projections-root .epr-meta/elohim/projections --composed-by "<your model id>". Confirm the command package has two projection edges and the verbatim sourceDocCid witness equals each projection CID.
- Commit the package path-scoped. Then plant the next command.
Invariants
- Never transform command bytes while planting. The entire
source.body, including optional frontmatter and trailing newline, is authoritative.
- Never re-import a package-master command from
.claude/commands; edit its package JSON instead.
- Never bulk-write all runtime projections for a one-command plant; use
--only CommandPackage:X.
- Keep identity shared across runtimes: one command id, one package root, two byte-identical projections.
- Compute CIDs only through eprfs (
eprfs-core::BlobCid::compute); never duplicate CID logic in JavaScript.
