description	/onboard procedure: read roster + team-memory + posture + claims + codify lease + rules-changed for a new operator joining a multi-operator COC repo.

/onboard — deterministic operator onboarding

This skill is the procedural detail for the /onboard command (.gemini/commands/onboard.md). The command is the entry point; this skill is the runbook the orchestrator follows.

When to use

• An operator opens a fresh session in a multi-operator COC repo for the first time.
• An operator joins a repo someone else owns and needs the shared state surface.
• After /clear / auto-compaction — the operator wants to re-validate the team-memory + posture + claim surface without inferring from a stale .session-notes.
• Pre-/codify sanity check: confirm no other operator holds the codify lease before drafting a proposal.

Read-only contract

/onboard writes ZERO state. Every read goes through an existing helper:

Surface	Helper	Returned shape
Operator identity	operator-id.js::resolveIdentity()	{display_id, verified_id, posture, blocked_into?}
Roster	roster-schema-validate.js + reading operators.roster.json	{operators: [{display_id, ...}]}
Team-memory	direct fs.readdir(.claude/team-memory) + fs.readFile per file + integrity-guard.js validation	[{slug, body, frontmatter, integrity_ok}]
Active workspace	workspace-utils.js::detectActiveWorkspace()	{workspace, recent_journal[]}
Posture	state-io.js::readPosture()	{posture, since, transition_history, pending_verification}
Adjacency claims	coordination-log.js::foldLog()	active-claim slice
Codify lease	codify-lease.js::readActiveLease()	{lease, leasePath}
Rules-changed	reuse multi-operator-sessionstart.js helper or re-derive via git log	list of rule files + MUST-clause line refs

If a helper returns a typed error (e.g. readPosture fail-closes to L1), /onboard surfaces the error verbatim per rules/zero-tolerance.md Rule 3.

Section-by-section runbook

1. Operator identity

identity = operatorId.resolveIdentity()
if (identity.blocked_into) → emit "/whoami --register" + stop

The blocked_into value (UNROSTERED_BLOCKED_INTO or NO_KEY_BLOCKED_INTO) is the action the operator must take. Do NOT proceed to subsequent sections if blocked — the rest of the briefing assumes a registered identity.

2. Team-memory surface

files = readdir(".claude/team-memory")
  .filter(f => f.endsWith(".md") && f !== "README.md")
for f in files:
  content = readFile(f)
  parsed = parseFrontmatter(content)
  if parsed.superseded_by → skip (historical record)
  integrity = integrityGuard.validate(content)
  if !integrity.ok → add to failed_integrity[]; continue
  emit {slug, body, signed: parsed.signed, promoted_by: parsed.promoted_by}

Sort by promoted_at descending so recently-promoted facts surface first.

The failed_integrity section is REQUIRED in the output even when empty — its presence is the operator's signal that the integrity check ran (an empty list with the heading is informative; a missing heading is ambiguous).

3. Active workspace + recent decisions

ws = workspaceUtils.detectActiveWorkspace()
# DEFER is NOT in journal-reserve.js::VALID_TYPES ({DECISION,DISCOVERY,TRADE-OFF,RISK,
# CONNECTION,GAP,AMENDMENT}); deferrals are DECISION-typed (topic carries "defer") and
# already surface under the DECISION filter.
recent = listJournalEntries(ws, limit=5, types=["DECISION","DISCOVERY"])
emit {workspace: ws, recent_journal: recent}

The journal listing excludes .pending/ (per existing M6 contract — pending entries are not yet committed and may carry uncleared sensitive content).

4. Posture + pending_verification

p = stateIo.readPosture(repoRoot)
if (p._fail_closed) → emit verbatim with fail-closed banner
emit {posture: p.posture, since: p.since, last_transition: p.transition_history[-1]}
if p.pending_verification.length > 0:
  emit "pending_verification: " + p.pending_verification.join(", ")
  emit "Your next response in a real session MUST include [ack: <rule_id>] for each."

5. Active claims + codify lease

Two independent helpers — combine into one section because they share the "what's locked right now" semantics.

claims = coordinationLog.foldLog({filter: "active_claim"})
for c in claims: emit {holder: c.display_id, path: c.path, expires: c.lease_expiry}

lease = codifyLease.readActiveLease(repoRoot)
if lease.lease:
  emit {holder: lease.lease.display_id, branch: lease.lease.branch,
        acquired_at: lease.lease.acquired_at, scope: lease.lease.scope}
  emit "Concurrent /codify is BLOCKED until released."
else:
  emit "No active codify lease."

6. Rules-changed

The M5 session-start hook (multi-operator-sessionstart.js) computes this surface. /onboard calls the same helper (extracted into a shared library at M5 time) OR re-derives via git log --since against .claude/rules/.

For each modified rule file, grep for MUST clauses (grep -n '^### .*MUST') added/changed in the diff window. These are the candidates for pending_verification per rules/trust-posture.md MUST-6 (grace-period semantics).

7. Action items

The actionable footer. Format:

## Action Items

- [ ] Acknowledge: include `[ack: <rule_id>]` in next real-session response (for each pending_verification entry)
- [ ] Repair integrity: <slug>.md frontmatter invalid (for each failed_integrity file)
- [ ] Posture: current L<N>; upgrade requires <gate> (only if posture < L5)
- [ ] Lease: held by <other_operator> on branch <branch> — wait for release before /codify

Empty when nothing requires action — the empty list IS the green-light signal.

--json mode

Emit a single JSON object with the seven section keys:

{
  "operator": {...},
  "team_memory": {"facts": [...], "failed_integrity": [...]},
  "workspace": {"name": "...", "recent_journal": [...]},
  "posture": {...},
  "claims": [...],
  "codify_lease": null | {...},
  "rules_changed": [...],
  "action_items": [...]
}

The schema is stable — downstream tooling (CI, audit scripts, repo-ops dashboards) MAY parse the JSON output as the canonical state snapshot.

Composition with other commands

• /whoami answers "who am I" — /onboard answers "who am I AND what's the team state". /onboard calls resolveIdentity internally but surfaces more.
• multi-operator-sessionstart.js auto-renders a subset on every session start. /onboard is the on-demand full read.
• /claims lists adjacency claims only. /onboard includes the same data plus the codify lease.
• /posture shows the posture in isolation. /onboard shows it inline with everything else.

There is no overlap-as-duplication risk because /onboard is read-only and the other commands either write state or render a single surface. Calling /onboard then /claims is fine — the second call just re-reads.
