Tracker — Ξ-recalibration grid regeneration

Written 2026-10-02 by /track-progress grid layout pipeline. Hand-maintained from here on, under /checklist's reconciliation rule: ticks are never rewritten, items are not deleted. Rendered by agent-workflow-kit/render_checklist.py log/trackers/grid_regeneration.md to output/html/trackers/grid_regeneration.html.

What this tracks. The maintainer authorised a Ξ-consistent enterprise-premium recalibration on 2026-10-02: EU/RoW e 0.222233 → 0.219545 (North/South stays at its already-Ξ-consistent 0.225457). gold_fit1 and fiat_fit1 were selected, independently audited, and promoted into data/initial_state/canonical_initial_state.xlsx. The remaining step — regenerating the four EU/RoW baselines, the 96-cell scenario grid, the response/cluster/classify/structure analyses, and a separately-named OPENFLEX re-experiment — is the regeneration pipeline (tools/calibration/regenerate_xi_results.py), completed and committed at 50b5520; current tag 20261002_xi.

The one real finding this session. The recalibration pushed the quasi-float (crawling EU rate) EU debt/VA OLS slope from −6.45e-05 to −1.029e-04, 2.9% over the 1e-4 stationarity gate. Measured: the debt endowment moves the debt level one-for-one but does not move the slope (d1 −49.78 → −57.6 left the slope at −1.030e-04 while debt/VA 0.806 → 0.799); λ and the tax scales do move the slope but are knife-edge (λ 0.0353 → 0.0300 flips Z1 debt/VA 0.806 → 1.763 and the slope −1e-04 → +6.7e-03; s 1.0 → 1.05 drives it to −5.99e-04). Decision (maintainer): document the drift, not chase it — that one row is whitelisted in the pipeline's gate, bounded at |slope| < 1.5e-4.

Completed pipeline and durable receipts

• Not reconciledRegeneration pipeline — 96/96 accepted, zero failures; 48 North/South caches hash-preserved; response/classification/cluster/structure analyses complete. regeneration_complete.json and data/current_results.json identify 20261002_xi.
  stage: complete
• Not reconciledCommit the promoted workbook — promotion committed at d02fb7a, receipts/results at 50b5520.
• Not reconciledCommit the quasi-float whitelist — the bounded documented exception is implemented.
• Not reconciledCommit the small receipts — promotion, replacement, baseline, completion and preservation receipts tracked.

Blocked on me — maintainer decisions

Three of the four author choices remain open; the fourth (Ξ premium) is now resolved and implemented.

• Blocked on meΞ-consistent premium — authorised 2026-10-02; e 0.219545 promoted.
  decision: resolved
• Blocked on me🚧 Scenario 6 policy scope — net-investment versus replacement-capital meaning.
  decision: open
• Blocked on me🚧 par_xr — provisional 0.15; the quasi-float adjustment speed the baseline does not identify.
  decision: open
• Blocked on me🚧 Negative South fiat reserve — the North/South OPENFIX-fiat baseline holds the South CB short −11.5 of North bills; institutional admissibility undecided.
  decision: open

Forgotten

• Forgottentools/calibration/recalibrate_quasifloat.py — written this session on the premise that the debt endowment controls the quasi-float slope; the probe falsified it (level-only). It is a dead end and untracked. Decide: remove it, or mark it superseded and keep as a record. — measured 2026-10-02
  stage: falsified premise

Delivery after regeneration

• Not reconciledBefore/after recalibration report — rendered HTML/PDF with the strict-stationarity failure and instrument probes stated.
• Not reconciledOPENFLEX old/new feedback comparison — trajectory extraction, temporary pulses, reference-path Ξ ablation and precision/constraint checks complete; complete causal-loop identification remains scientific work.
• Not reconciledViewer/site/context refresh — current 20261002_xi viewers/site rendered and browser-checked; knowledge base refreshed from measured artifacts.

Closed — done this session

• ClosedSelection audit re-check — SELECTED CACHE AUDIT PASSED (gold debt/VA 0.8101/0.8500, fiat 0.8100/0.8500; slopes < 1e-4; finite; consistency < 2.2e-8). — tools/calibration/audit_xi_selection.R
• ClosedWorkbook promotion — e 0.222233 → 0.219545 plus the five gold/fiat instrument cells.
• ClosedQuasifloat slope diagnosis — debt endowment level-only; λ/tax knife-edge; drift is e-driven. — qf_lambda_probe, qf_tax_probe, quasifloat_d1_probe receipts
• ClosedQuasifloat exception decision — document the −1.029e-04 drift and whitelist it (bounded).
