Adaptations: - DROP FIRST-ACTION clause from prelude template — teammate frontmatter now absorbs role-establishment context (per audit-architect Q5 ADDENDUM rationale). - ADD 1-line charter cross-ref to prelude template — points new teammates at protocols/pact-communication-charter.md before they send teammate messages. Closes F9 charter-omission gap as a single-restoration two-finding-closure. Surgical fix (beyond byte-equal): - Update _TEACHBACK_REMINDER: pre-deletion pointed at /PACT:teammate-bootstrap (also deleted in #621). Now points at the canonical pact-teachback skill and metadata.teachback_submit contract. Restoring byte-equal would ship a broken reference. Test coverage (160 tests across 3 files): - test_peer_inject.py: 73 tests, 5 adapted for new contract (charter cross-ref assertion replacing FIRST-ACTION assertion; pact-orchestrator excluded from SubagentStart agent-types per --agent flag delivery model). - test_error_output.py: +TestPeerInjectSuppressOutput class (2 tests). - test_spawn_overhead_benchmark.py: +2 peer_inject methods asserting prelude byte-cost reduction (FIRST-ACTION drop > Q5 ADDENDUM add). Security: _sanitize_agent_name marker-spoof injection defense preserved verbatim (newline / ')' / control-char rejection).
