Stage 3 of the realism migration. Replaces orchestrator/scheduler.py's
hardcoded _FILE_TEMPLATES/_USERS (3 templates emitting epoch-suffixed
filenames like notes-1777315854.txt with identical bodies per
template) with a persona-driven realism engine.
New surface:
- SyntheticFile SQLModel (synthetic_files table, UNIQUE on
decky_uuid+path) — per-(decky, path) state for the future
edit-in-place flow. Pre-v1, no _migrate_* helper.
- BaseRepository methods: record_synthetic_file,
update_synthetic_file, list_synthetic_files,
pick_random_synthetic_file_for_edit (used by stage 3b).
- realism/naming.py: per-content-class filename templates,
persona-conditioned. /var/log/cron.log + logrotate skeleton for
system-class; /home/<persona>/TODO.md, scratch.md, etc. for
user-class. Anti-regression test pins "no 8+ digit decimals in
basenames" (the realism failure today).
- realism/bodies.py: deterministic body templates per content_class.
TODO body uses checkbox markdown, script body has a shebang, cron
body matches syslog cron shape ("CRON[PID]: (user) CMD (...)").
- realism/planner.py: pick(deckies, now, rng) returns a Plan.
Diurnal-gated, weighted user/system content split (70/30 user
bias). Create-only in stage 3; edit branch lands in stage 3b.
Scheduler split:
- scheduler.pick is now traffic-only (sync).
- scheduler.pick_file is async, takes a repo, resolves personas
(Topology.email_personas for topology-source deckies; global
realism.personas_pool otherwise), and maps Plan -> FileAction.
- FileAction gains persona/content_class/mtime fields.
Worker:
- _one_tick rolls 50/50 between traffic and file each tick. After a
successful FileAction plant, _record_synthetic_file persists or
patches the synthetic_files row (catching the unique-constraint
collision on re-plant of the same path).
- SSHDriver._run_file passes action.mtime through to plant_file so
files don't all stamp at wall-clock-now.
Empty subpackage skeleton for the realism migration: ContentClass enum
(file/email/canary content categories), Plan dataclass (frozen, with
edit-action invariant), in_work_hours window check (wrap-around
supported, fail-open on parse error), and sample_mtime for backdated
file timestamps that snap into a persona's active hours.
Stage 1 of the orchestrator+canary realism unification — no
production caller wired yet; planner.pick is a stub returning None
until stage 3.
