Every zeroclaw mission minted a fresh team of claws. They are created
`lifecycle = 'permanent'` and nothing reaps them until the MISSION is deleted,
so the roster grew by a whole team per mission while each member worked exactly
once — "My Workforce" was a list of strangers, and upskilling had nothing
durable to act on.
A mission now hires the claw that already does the job, matched on
`agent_template_link (template_id, role_slot)`, minting only what is missing.
Oldest first, so reuse concentrates on the same few claws and their brains
actually accumulate rather than spreading thinly across a growing pool.
A claw on a RUNNING mission is not offered. Two missions driving the same
ZeroClaw agent and the same `.brain` at once is a data race with a model on the
other end of it, and minting a second claw is much cheaper than reasoning about
that.
A reused claw is NOT re-seeded from the template's brain_seed — that would
overwrite what it learned with its starting point, which is precisely the
accumulation this exists for.
Names are the role now (`planner`), not
`"{mission} · {purpose} · {template} · {slot}"`. That produced
"verify: a repo-less research mission keeps its output · mission · Rust SDLC ·
planner" — unreadable in the roster, the API and every log line at once. Which
mission a claw is on is context a caller can join to; it is not its name.
And the half that makes reuse safe rather than destructive: deleting a mission
now purges only claws no OTHER mission still employs. Without it, tidying up one
mission deletes staff another one holds — presenting as the roster quietly
shrinking rather than as an error. A test asserts the guard exists inside the
reaper AND runs before the purge, because a check after it is decoration.

Ships the lineage layer that ties agents back to their team template
and wires the MCP skills server to actually merge template default
skills with per-agent overrides.
Migration 0050 adds `agent_template_link` (agent_id PK, template_id,
template_version, role_slot, seeded_at, created_at + indexes for
template/role lookups). Populated at agent-materialization time by
Slice 4's mission-launch orchestrator; read here by the skills MCP
server and by future level-up (Slice 8.5).
New Rust surface:
- cm_db::repo::agent_template_link (upsert / get / mark_seeded /
agents_for_template — the last is what level-up's "prompt upgrade
on template N+1" query needs)
- cm_api::brain_seed::ingest(claw_id, seed_md, identity_prompt)
opens cm_brain::ClawBrain on spawn_blocking, sets system_prompt
on first touch, writes seed as agent_md, commits. Idempotent —
skips when agent_md already populated.
- cm_api::mcp_skills::mcp_skills tools/call now resolves the caller
agent's template + role via agent_template_link and merges
template default skills with per-agent overrides (was overrides-
only in Slice 3.5b).
- cm_api::team_template_loader now binds template_role_skills after
upserting each template — looks up each declared skill by name,
attaches with pin_in_context=true for foundation skills and the
first two role skills. Missing skills log + skip.
- Boot ordering: skills load BEFORE team templates so the binding
lookup resolves.
Follow-up (Slice 4): mission-launch orchestrator calls brain_seed::ingest
+ agent_template_link::upsert when minting a team from a template.
Until that lands, the link is populated only by manual writes; the
MCP merge is silent-no-op for agents without a link (falls through
to overrides-only), which matches the pre-3.5d behavior.
