Karkinos v0.3.1

Karkinos v0.3.1 is a compatibility and release-safety hotfix for v0.3.0.

Fixes

• Repairs only the exact known legacy v0.3.0 SQLite baseline that lacks account_truth_review_fingerprint, and only while controlled posting and correction tables are empty.
• Preserves the original v1 migration checksum and provenance, validates applied v1-v8 schema artifacts, and fails closed on malformed, conflicting, partial, or unreconciled state.
• Serializes image publication and prevents an existing SemVer or commit-SHA image tag from being overwritten; ambiguous registry responses also fail closed.
• Keeps broker-provider-free research, planning, paper, shadow, and provider-neutral strategy-iteration workflows available. Real broker submission and cancellation remain disabled by default.

Release identity

• GitHub tag: v0.3.1
• Version image: ghcr.io/imreese/karkinos:v0.3.1
• Revision image: ghcr.io/imreese/karkinos:sha-aa8a88c988eb9ae6f483b9b01cf49f59c4cc2fed
• Multi-architecture digest: sha256:081d1ba6e32134133780760d50c5eb5b170c661cd59ad779537a71b7c8274901
• Stable aliases latest, v0, and v0.3 point to the same digest.
• The published v0.3.0 image remains unchanged.

Upgrade note

Back up the SQLite database before upgrading. Startup applies the narrowly-scoped legacy repair atomically; unknown or unsafe database states stop instead of being guessed through.

This software release does not claim live-provider validation or real-money readiness. Human confirmation and fail-closed controls remain authoritative.

Karkinos v0.3.0

Karkinos v0.3.0 is a broker-provider-free software release: it packages
research/backtesting, persisted financial evidence, daily planning,
paper/shadow, OMS/reconciliation, and the provider-neutral controlled-execution
foundation. It does not select, register, contact, or require a real broker
adapter and does not claim real-money readiness.

AI strategy research — methodology fixes

• Sealed-time holdout — separates model-visible validation from the final
  champion evaluation, with one-time partition consumption.
• Multiple-testing correction — Holm-Bonferroni, Deflated Sharpe Ratio, and
  Probability of Backtest Overfitting (CSCV); the advancement gate applies a
  deflated-Sharpe check.
• Challenger baselines — deterministic (MA-crossover / RSI-reversion /
  momentum grids) and seeded-random Formula DSL challengers compared against
  the champion on the sealed holdout.
• A-share execution constraints — daily price-limit (up/down) and
  suspension checks on the formula backtest path; lot rounding and T+1 remain
  in the canonical engine.
• Point-in-time universe membership — survivorship-bias validation against
  persisted market-universe snapshots.
• Daily token budget — atomic per-market-date enforcement on provider calls.
• Reasoning-mode ROI guard — strategy research disables model reasoning.

Release engineering

• tools/release_image_plan.py — fail-closed semver-tag → GHCR multi-arch image
  plan.
• CI publishes ghcr.io/imreese/karkinos:<tag>, :sha-<commit>, and stable
  aliases on semver tags.

Real-money execution remains disabled by default. v1.8 broker-connected pilot
gates are unchanged.
