SDG strategy

active

Content-addressed record of how a Signals data product was made.

SDG strategy is the “how it was made” data product, sibling of SDG corpora. A run is determined by the provenance triple (window, strategy, code). This repository holds the middle vertex: every outcome-shaping factor that is neither the input window nor the code commit.

strategy_id is a 12-character SHA-256 of the sorted component hashes. It is verifiable from any Signals project with no Ægir context. Release tags and zettel ids are names; manifests/<strategy_id>.json is the Merkle tree; CURRENT names the checked-out strategy on trunk.

Four pillars

lens — Qdrant aperture snapshot (concept ids, labels, vector hashes)
voices — agent-facing surfaces: prompts, schemas, feedback templates, MCP tool docstrings, writer profile, backend config
knobs — the flow’s tunable defaults
targets — what it aims at: SchemaPile norms, gate floors, brand lexicon

Shadows are branches from trunk. Promotion is cherry-pick or merge; consumers pin by ref. Ægir maintains the manifests (python -m aegir.strategy.manifest). Lineage surfaces (Atlas / OpenLineage) carry the same strategy_id.
