02 — Decorated-Generated Repoint Pack

Classification: READY_OPERATOR_GATED (engineering-complete) → DO-NOT-NOW. Repoint is engineering-ready with a complete sequence + rollback, but the current decision is DO NOT repoint now: production _current is green (no upside), the only candidate is circular, and TRUE no-hardcode decoration is authority-gated. Verdict on record: DECORATED_GENERATED_REPOINT_READY_OPERATOR.

Objects

  • Candidate (circular — do NOT repoint to this as-is): v_rp_universal_node_ui_contract_decorated_generated_candidate = generated_v2 backbone joined with current decoration.
  • Generated backbone v2: v_rp_universal_node_ui_contract_generated_v2 (87 rows, md5 a79c9560…; v1 was 2a9c1f00…).
  • Full-column parity proof: v_rp_decorated_generated_full_column_parity = FULL_COLUMN_PARITY_PASS — 87/87 rows (gen_only 0, cur_only 0), 0 count diffs, route/action/reliability 87/87, substrate 81/87 (the 6 NULLs are by-design; current carries them too). Backed by fn_rp_decorated_generated_parity() (function-backed, OOM-safe).
  • Readiness dashboard: fn_rp_generator_replacement_readiness() / v_rp_generator_replacement_readiness_dashboard = DECORATED_GENERATED_REPOINT_READY_OPERATOR (parity PASS, guard PASS, OOM_SAFE, repointed=false, no_hardcode_ready=false).

The circular-dependency hazard (the reason for the non-circular rebuild)

The candidate sources its decoration from _current, which is a thin ALIAS of v_rp_universal_node_ui_contract_current_v2. If you repoint _current to a view that itself reads _current, you create a recursion. A real repoint MUST rewire decoration to _current_v2 (the real definition), not _current (the alias).

Backbone-only caveat (critical)

The generator regenerates the backbone (membership + count) only — NOT the decoration layer (label / route / substrate / badges / reliability), which the v1 contract bakes into each leg and which the UI _current stack depends on. DO NOT repoint the current alias to the bare, undecorated generated backbone — that loses decoration and breaks the UI package.

Engineering-ready repoint sequence (operator step; from RUNBOOK_v2 §3)

  1. Build a NON-circular decorated-generated view: copy the candidate but source decoration from v_rp_universal_node_ui_contract_current_v2 (NOT _current).
  2. Re-prove full-column parity of the non-circular view vs _current_v2 (expect 87/87, same profile).
  3. Stage rollback: capture the current _current alias definition.
  4. Repoint: redefine v_rp_universal_node_ui_contract_current to select from the new non-circular view.
    • Alias mechanics: use CREATE-OR-REPLACE only if the new view is a column-SUPERSET in the same order; if columns are reordered/inserted mid-list, you MUST DROP + CREATE.
  5. Re-run the full proof chain: deploy guard, invariant, computed proof, smoke, anti-false-green, and the OOM detector (must show 0 CRASH_LANDMINE).

Expected RP-state change on repoint

  • _current backbone derivation switches from hand-built to generator-driven; decoration stays hand-built (_current_v2). readiness dashboard repointed flips false→true.
  • NO change to no-fake invariants (ownership/votes/RP/REALRUN untouched).

Rollback

  • Restore the captured _current alias definition (step 3).
  • Drop the new decorated-generated objects: v_rp_decorated_generated_full_column_parity, fn_rp_decorated_generated_parity(), v_rp_universal_node_ui_contract_decorated_generated_candidate, v_rp_final_operating_acceptance_dashboard / fn_rp_final_operating_acceptance(), v_rp_generator_replacement_readiness_dashboard / fn_rp_generator_replacement_readiness().
  • Exact DROP statements are in RUNBOOK_v2 §4 on FS.

Why DO-NOT-NOW (no-go for repoint at this checkpoint)

  • Production _current / _current_v2 are green; repoint has no current upside and adds risk.
  • The only existing candidate is circular (must be rebuilt non-circular first).
  • TRUE NO-HARDCODE (registry-driven decoration = the 58 view-edits, no_hardcode_ready=false) is AUTHORITY-gated: requires AX-PXT candidate-register + AX-TRIGGER owner/president register (see doc 04). Do this only when authority lands or an operator explicitly requests the backbone swap.
