Two new DefineActivity SX files in next/genesis/activity-types/
per design §13.5 / Step 11:
announce.sx — Re-broadcast a peer's activity to followers.
:object is the CID of the activity being announced.
:schema requires :object to be a string.
Followers see the Announce in their inbox; their projection
decides whether to fetch the wrapped activity body.
endorse.sx — Cross-actor signal on a target activity.
:object is the target activity's CID; :kind is the
endorsement variant (e.g. 'like', 'share').
:schema requires both :object and :kind to be strings.
Projections aggregate endorsements into counters / heat /
ranking signals.
M1's Note object-type is unchanged — Create{Note{...}} is still
the publish path for short authored messages. The runtime-publish
demo (verb extensibility via Create{DefineActivity{...}} at
runtime) from M1 §9a continues to work; these files are the
genesis pre-shipped variants for v2 baseline so peers don't have
to negotiate verb definitions on first contact.
Manifest extended:
:activity-types 3 -> 5 entries
total genesis 34 -> 36 entries
Hardcoded count assertions bumped in:
bootstrap_read.sh (activity_types 3->5, first-section-count 3->5)
bootstrap_load.sh (activity_types 3->5)
bootstrap_populate.sh (total 34->36, activity_types 3->5)
bootstrap_start.sh (activity_types 3->5, total 34->36)
genesis_parse.sh +4 cases (head form + name for both files).
bootstrap_populate.sh internal sx_server timeout bumped
300s -> 600s to fit the larger genesis bundle.
61/61 in genesis_parse.sh, 15/15 in bootstrap_read.sh,
15/15 in bootstrap_load.sh, 14/14 in bootstrap_populate.sh,
12/12 in bootstrap_build.sh.
