Per CEO approval 2026-10-04. Option (a): overwrite v1 with v2. Changes: * send-mailbox-message.sh - production implementation with zero placeholders. Real rail callbacks via urllib.request POST to submit_request. EXECUTOR_API_KEY in Authorization header only. * delivery-pack.sh - informational template (main script generates per-recipient copies inline). * SKILL.md - v2 spec (what's new + what's the same). * v2-vs-v1-diff.md - side-by-side diff. * README.md - bundle index. Honours brief locked decisions [1]: - Decision 2: outbox canonical; inbox mirrored (own inbox only). - Decision 6: mailbox writes AUTO_RUN per recipient. - Decision 7: append-only inheritance; this skill is additive. - Decision 8: naming convention coreci-<role> validated at parse. - Decision 9: extend, don't duplicate. Does NOT (per brief): - Edit coreci/agent-definitions/ (read-only per Rule #7). - Implement deny_read_targets (xfail; out of scope). - Classify mailbox writes as NEEDS_APPROVAL. - Write to anyone else's outbox/. - Provide cross-repo atomicity (per-recipient only).
