split-fence: independent implementers, independent trees. A's fence stays: no second plugin, no poteto-mode, no Benny, musl CLI iced-free, `ljos vote --as` and DeGroot stay.
prove-on-real-surface: measure on the host the users run. A cheaper substitute is not the result.
open-sibling-first: a second implementer opens a sibling leftover, not a rewrite of the first tree.
arena-then-compose: designs write scratch; the host writes a rubric on a compose child; personas vote the compose `--as`.
one-step-delegate: a subagent is one playbook step. No resume across phases. A new task is a new sitting.
";
pub const RUBRIC: &str = "\
== rubric
1. Ledger intact. `ljos vote --as` and DeGroot stay. No schema_yes, no BARMA, no host for-loop of accepts.
2. Playbook before panel. Sitting names one recipe and copies it before personas enter.
3. Rubric in brief. `ljos brief` carries the playbook step, these principles, and this sheet.
4. One-step delegate. Subagent = one playbook step. No resume across phases.
5. Unscoped inbound trust. Every panel persona has one unscoped inbound row; `--about` only adds weight.
6. No second plugin. Do not copy 47 skills, poteto-mode, Benny, or Cursor model files.
7. Small surface. Prefer pack atoms and brief fields over a new crate. Musl CLI stays iced-free.
8. Named principles. Five families, invocable mid-sitting, mapped onto existing law (split-fence, prove-on-real-surface, open-sibling-first, arena-then-compose, one-step-delegate).
";
const SIT_BODY: &str = "\
A sitting on one issue. Name this recipe at open (`ljos sitting ISSUE --playbook sit` or `ljos playbook ISSUE sit`). The sitting prints this body before recall and holds the name until finish or release.
1. Open with `ljos sitting ISSUE --playbook sit`. Read doctor, cards, due, island, this recipe, recall, timeline, claim.
2. Grade due claims (`ljos graded ID`).
3. Do the work on this claim only. Artefacts are deeds, then `ljos deed ISSUE --add ACCESSION`. Lessons are `ljos remember` in two sentences.
4. One playbook step is the whole sitting. A subagent takes this recipe and this issue; it does not resume a later phase.
5. Close with `ljos finish ISSUE --lesson \"...\"`. Completing the node does not close the ticket. `ljos finish ISSUE --close` does, when the work is accepted.
";
const ARENA_BODY: &str = "\
Designs compete; the host writes a rubric; personas vote a compose, not the designs.
1. Bind this recipe: `ljos sitting ISSUE --playbook arena` or `ljos playbook ISSUE arena`.
2. Each design writes scratch (summary and body). Do not vote the design children as accept-at-most-one.
3. The host writes a compose child and a rubric with named axes. Personas vote the compose `--as`.
4. Spawn hints are optional model-family names on this atom. Each subagent still ends with `ljos vote ISSUE --for accept|reject --as NAME`. No graft. PASS on an axis is not GREEN.
5. `ljos consensus ISSUE` settles under trust rows and DeGroot. `ljos vote --as` stays.
";
const LAND_BODY: &str = "\
Land a chosen design on the real surface.
1. Bind `land`. Sitting copies this body before recall.
2. Prove on the real surface: the host the users run, the crate they install. A cheaper substitute is not the result.
3. Keep A's fence: no 47 skills, no poteto-mode, no Benny, musl iced-free, `ljos vote --as` and DeGroot stay.
4. One step per subagent. Open a sibling first when a second implementer is in flight.
5. Close with finish. Do not ship a count as consensus.
";
const COMPANY_PANEL_BODY: &str = "\
A panel of personas on one bound recipe.
1. Bind `company-panel` before any persona enters. `ljos panel` refuses if none is bound.
2. Every persona has one unscoped inbound trust row; `--about` only adds weight.
3. `ljos brief NAME ISSUE` reprints this recipe in full, the five named principles, and the arena rubric.
4. One subagent per persona, optional model-family spawn hints. Each casts `ljos vote ISSUE --for OPTION --expect OPTION --as NAME`. `--expect` is the private forecast of the others, for the surprisingly popular reading. Then `ljos consensus ISSUE`.
5. Do not resume across phases. A new task is a new sitting.
";
const OVERNIGHT_BODY: &str = "\
Drive work while unattended, still one sitting.
1. Bind `overnight`. Name a checkable finish condition on the issue.
2. One playbook step per subagent. No session-pickup, no resume across phases.
3. Isolated worktree. Prove on the real surface before claiming done.
4. Decision log is tracker notes and deeds, not a second ledger.
5. `ljos finish` when the condition holds; otherwise `ljos release` and a new sitting.
