Pre-work for a writing-curriculum extension to CORE. Two companion
documents, both Proposed status (no code shipped).
docs/decisions/ADR-0087-rhetorical-style-axis.md
Pins rhetorical style as a third selection axis — sibling to anchor
lens (ADR-0073), orthogonal to register (ADR-0070). Substantive
axis: trace_hash DISTINCT across styles (style changes which moves
the composer requires and which frames the realizer emits, which
changes the propositional plan, which changes the trace).
Four anti-patterns explicitly named and rejected:
- style as motor (re-couples realizer to geometry; same shape as
the ADR-0085 fusion-operator rejection)
- style as register variant (conflates substantive with stylistic)
- style as identity axis (bloats identity doctrine)
- style auto-detected from user input (operator-chosen only)
Pack shape mirrors packs/anchor_lens/. default_unstyled_v1 is the
null-lift pack identical to no-style behavior. Three CI invariants
proposed: rhetorical_style_null_lift, schema validation, three-axis
orthogonality.
Substrate-only ADR — no consumer code, no genre packs. Consumer
integration is a follow-up ADR (composer + realizer extensions
that read permitted_frames + required_moves_per_claim +
forbidden_moves).
docs/curriculum/writing-chain-harvester-spec.md
Layer 0 of the writing curriculum. A deterministic tool that
extracts candidate (subject, predicate, object) triples from
reviewed expert prose and surfaces them as proposals to the
existing teaching/review pipeline.
Five stages (segment → classify → extract → propose → audit) —
pure-Python rule-based, no LLM generation, no auto-acceptance.
Trust boundary: reviewer accept/reject via the existing
core teaching propose/review path. No bypass permitted.
The harvester is a proposal PRODUCER, not a proposal CONSUMER.
Plugs into the existing pipeline without inventing a new review
mechanism. Each proposal carries source_id + source_line + the
exact source_clause it came from for reviewer verification.
First-implementation acceptance criteria deliberately tight:
Stage 0+1 with dry-run only. Stages 2-5 are follow-up PRs.
Substrate-first sequencing pattern (ADR-0084 → 0085) reused
throughout. Both documents acknowledge open questions deferred to
implementation phase rather than pre-deciding.
Why now: a writing curriculum is being scoped. Without this ADR,
every downstream PR faces the same "should style be a motor?"
question and the temptation to reach for the geometry will recur
every time the realizer produces a stilted surface. Pinning the
axis up front prevents that recurrence.
