Module tool_defaults 

Paper 3 — built-in default ToolValueModels for selected common tools by corpus volume.

Anchored on docs/research/paper3_corpus_findings.md (P-3-01). We ship defaults for a curated subset of the highest-volume tools (the canonical patterns from §Real-world patterns); the corpus has more tools above the 100-session threshold, but the long tail either reuses one of the shipped defaults via [tools."*"] or is overridden per-installation. Users can override any seeded annotation through [tools.<name>] in pipeline_config.toml (Paper 3 §Provider extensibility).

The numbers below are priors — tune analyze will refine them against real telemetry, the same way Paper 2’s adaptive tuner refines the encoder profiles.

Functions

default_tool_value_models

Returns the seeded [tools.*] map every layered pipeline starts with. merge_right_wins lets the user’s TOML overrides win over these defaults.
