Highlights

Portable data-acquisition & technical-context substrate (#74)

A new stdlib-only layer at tools/mira_data/ that makes Mira's data contract executable — fetch, evidence-tier tag, compute, and emit — on free public data. Lite and supplementary: it strengthens ordinary-user analysis; it does not replace commercial or proprietary data sources.

  • Adapters (keyless): SEC companyfacts (company_financials), Yahoo v8 chart (market_price), BLS (macro_series).
  • Evidence discipline: every field is born tagged with its registry tier (Yahoo = L5 market_pricing; SEC / BLS = fact), so an aggregator value can't masquerade as an official fact. Mira-computed numbers are ledgered; issuer-disclosed values are reported.
  • Technical engine: pure-stdlib indicators (MA / returns / relative strength / z-score / realized vol / ATR / drawdown) → technical-analysis-check.csv + state tokens; options / short-interest / intraday stay source_gap.
  • Fundamentals deltas: YoY / CAGR from companyfacts as derived, ledgered records.
  • Artifacts: dataset-manifest / ingestion-log / evidence-log (v1.2) / calculation-ledger — all pass validate_repo unchanged. Bundle validator + just data-* recipes.
  • technical-context overlay wired into routing; methodology trial (COHR / CRWV / AAPL) recorded — reproducibility milestone met, kept in trial.
  • Config: SEC fetches are gated on a real contact in private/mira-data.env (see templates/mira-data-config.example).

Quick start:

cp templates/mira-data-config.example private/mira-data.env
just data-fetch company_financials AAPL
just data-technical AAPL
just data-fundamentals AAPL

Also in this release

  • Research report interpretation workflow (#75)
  • Reasoning-layer ablation trial archived as a pre-registered negative result (#73)
  • Minimum entry gate folded into the ChatGPT conversation instructions (#71)
  • Stale repository artifacts pruned (#72)

Verification

validate_repo (strict) + routing-schema tests are green on the release commit; the data substrate is live-verified against SEC / Yahoo / BLS endpoints. The core is zero-dependency stdlib.
