Module: Textus::Boot

Defined in:
lib/textus/boot.rb

Overview

Read-only “what’s in this store and how do I use it” envelope. A single call gives an agent the working model of a textus-managed project: zones and their write authority, entries and their flags, registered hooks, write flows, and the CLI verb catalog.

Boot is side-effect-free.

PROTOCOL_ID = 
PROTOCOL
WRITE_FLOW_TEMPLATES =

Per-capability write-flow templates. Each lambda receives the user-facing role name and the manifest, and returns guidance for that verb with the live zone named by kind (ADR 0034). A role holding multiple verbs gets one joined string; roles whose verbs have no template are omitted.

{
  author: lambda do |name, manifest|
    "edit files in #{zone_label(manifest, :canon, "your canon zone")}, " \
      "then 'textus put KEY --as=#{name}'"
  end,
  keep: lambda do |name, manifest|
    "keep durable notes in #{zone_label(manifest, :workspace, "your workspace")}: " \
      "'textus put KEY --as=#{name}' (no accept needed)"
  end,
  propose: lambda do |name, manifest|
    authority = manifest.policy.roles_with_capability("author").first || "the author-holder"
    "propose changes by writing #{manifest.policy.queue_zone}.* entries with --as=#{name} " \
      "and a 'proposal:' frontmatter block; the #{authority} role runs 'textus accept' to apply"
  end,
  fetch: lambda do |name, manifest|
    "fetch #{zone_label(manifest, :quarantine, "quarantine")} entries with " \
      "'textus fetch KEY --as=#{name}' (uses the entry's declared action)"
  end,
  build: lambda do |_name, manifest|
    derived = zone_label(manifest, :derived, "derived")
    "'textus build' computes #{derived} entries from projections; " \
      "#{derived} files are never hand-edited"
  end,
}.freeze
AGENT_PROTOCOL_TEMPLATE =

Static, store-independent parts of the agent-facing protocol. The ‘recipes` and `role_resolution` blocks are derived per-manifest in agent_protocol(…) because zone and role names are user-configurable.

{
  "envelope_shape" => {
    "summary" => "every read/write payload is a JSON envelope with _meta, body, uid, and etag",
    "fields" => {
      "_meta" => "hash of structured frontmatter; schema-validated per entry family",
      "body" => "string payload (markdown/text) or nil for json/yaml formats where body lives in _meta",
      "uid" => "stable 16-char hex identifier; preserved across writes and key renames",
      "etag" => "content hash; pass back on writes to detect concurrent edits",
    },
    "ref" => "SPEC.md §8",
  },
}.freeze
CURATED_CLI_VERBS =

Curated agent-facing verb catalog. For verbs that have a Dispatcher contract, the summary is derived from ‘contract.summary` at load time (ADR 0039). The editorial strings below are the fallback for CLI-only verbs without contracts. CLI_VERBS itself is assigned in textus.rb after Zeitwerk eager_load so that all contract-declaring files are loaded before derivation runs.

[
  { "name" => "boot" },
  { "name" => "list" },
  { "name" => "get" },
  { "name" => "where", "summary" => "resolve a key to its zone and path without reading" },
  { "name" => "schema" },
  { "name" => "put" },
  { "name" => "propose" },
  { "name" => "accept",   "summary" => "apply a queued proposal to its target zone; requires the author capability" },
  { "name" => "key",      "summary" => "key operations: 'key mv', 'key uid'" },
  { "name" => "delete",   "summary" => "delete an entry; --as=<role>" },
  { "name" => "build",    "summary" => "materialize derived entries; publish_to and publish_each fan out copies" },
  { "name" => "fetch" },
  { "name" => "freshness", "summary" => "per-entry freshness report (status, age, ttl, on_stale)" },
  { "name" => "audit",    "summary" => "query .textus/audit.log with filters (key, role, since, correlation-id, ...)" },
  { "name" => "blame",    "summary" => "audit rows for one key joined with git commit metadata" },
  { "name" => "rule",     "summary" => "inspect effective rules: 'rule list', 'rule explain KEY'" },
  { "name" => "doctor",   "summary" => "health-check the store (missing schemas, illegal keys, sentinel drift, etc.)" },
  { "name" => "hook",     "summary" => "list and run registered hooks: 'hook list', 'hook run NAME'" },
  { "name" => "pulse" },
].freeze
CLI_VERBS =

Derive CLI_VERBS after eager_load so all contract-declaring files are present (boot.rb loads first alphabetically; Dispatcher contracts are declared later).

.build_cli_verbs ⇒ Object

Build the CLI verb catalog by deriving each summary from the corresponding Dispatcher contract when one exists, falling back to the editorial string for CLI-only verbs without a contract (e.g. accept, build, where). Called once from textus.rb after eager_load so all contract files are present.
