"""SKV Guardian 2 (v3, cubes v2). Runs on the user machine, between their model and SKV. Keys stay in this process.

Guard 1 (server) only marks a missed step. Guard 2 does not let an answer out until the agent did its part:
  memory -> draft with service lines -> save turn -> Second Look -> rate new cubes -> clean answer to the user.
Service lines the agent must write (hidden from the user):
  L1: <stage summary, only when the guard asks: about every 15 turns; stages = done / decided / outcome; 5-8% of the raw text>
  L2: <headlines, rare: after 10 stage L1s; about 5% of L1>
  CRITICAL: <lasting fact, or none>
  CUBE: <kind> | <topic> | <one-line English essence> | <rule that changes the answer>   (kind: moment fact culture lifehack warning code)
     or CUBE_NOTHING: <why nothing here changes the answer>
  RATE: <cube_id> +1|-1 <reason>        for every cube marked "new, rate this" (a -1 needs a reason)
  TASK_DONE                              when the task is finished
  PUBLISH                                optional: share the cube (English, no secrets); otherwise it stays private
The guard never writes L1, cubes or ratings itself: it only refuses to pass an answer without them.

  TASK_DONE   only when the task is finished
  PUBLISH     only to share the cube (English, no secrets); otherwise it stays private
  seal: SKV | #N | READ | VERIFY | CORRECT | OUTPUT
Order: /api/v7/memory -> draft -> /api/v7/remember (turn, L1, critical, cube or cube_nothing) -> /api/v7/agent/second-look
-> /api/v7/experience/vote -> the person sees only the clean answer (service lines removed, seal kept).
A failing draft is sent back for up to SKV_G2_RECHECKS=2 re-checks with the reason; it is never held: the best safe final goes out with a short note. Guard 1 is the server: it marks a missed step or seal in /api/v7/memory reminders.
SYSTEM FILES (owner decision): touch server/system files (configs, /etc, /root, ops scripts, other users' data) only under an
explicit, time-limited owner grant. Before each action: POST /api/v7/sysperm/check {path, action: read|write|exec|delete, agent}.
allowed=false -> refuse and ask the owner for a grant (owner: POST /api/v7/sysperm/grant {scope, ttl_minutes<=240, actions, agent}).
allowed=true -> do only that action, then POST /api/v7/sysperm/log {grant_id, path, action, result}. Owner sees GET /api/v7/sysperm/audit, revokes with /sysperm/revoke.
FULL PROTOCOL (CUBE 05, done by the agent itself; Guard 2 only checks that every step is there):
  DRAFT: first answer
  SECOND LOOK: real reasoning over the draft's actual content: which claims are supported (ref: id) / [general] / [unverified],
               what may be invented, unclear or risky, what changes and why. Labels (claims:/safety:/fix:) are optional; a stamp is not.
  FINAL: the corrected answer the person sees, with refs/markers on every specific claim (numbers, dates, names, URLs)
Guard 2 asks for one redo if a step is missing, if FINAL is (almost) the same as DRAFT (no real re-check), if a specific claim has
no valid (ref: id) or marker, or if a ref is not a memory id it was given. Specifics still unsupported after the redo are tagged
[unverified] for the person. This maximizes care and lowers hallucinations; it does not guarantee 100%.
Settings: SKV_G2_PROTOCOL=full|v3, SKV_G2_MIN_CHANGE=0.03 (0 = off), SKV_G2_REFS=strict|mark|off, SKV_G2_CUBE_CAP=1, SKV_G2_CUBE_WINDOW=3.\nRitual Second Look (PASSED/ПРОЙДЕНА with zero findings) is rejected. Every specific fact needs (ref: event_id) or a marker. Cube ids you name must match the server. Cap: prefer CUBE_NOTHING if a cube was just created. If the user pastes sk_..., warn them to revoke it.
START: the first turn of a session loads /api/v7/memory/start as DATA (SKV_G2_START=off to skip). Your own system prompt:
SKV_G2_SYSTEM="..." or SKV_G2_SYSTEM_FILE=path.
