SYN-008
Heuristic
layer: sentence
Given information before new information
IF a sentence introduces new information before the anchor it depends on, THEN reorder from shared context to new contribution ELSE retain a deliberate surprise.
Why the rule exists
Readers integrate unfamiliar material more easily when it attaches to an available anchor.
Condition
The rule fires when this evaluates true. Paths marked below must be present in the fact base; the engine reports the rest rather than guessing them.
- ALL
- sentence.given_new_order eq "new_before_given"
- sentence.surprise_intended eq false
Facts this rule reads
| Path | Source |
|---|---|
sentence.given_new_order |
You supply it |
sentence.surprise_intended |
You supply it |
Then
- reorder — target
sentence.information_structure
Else
- retain — target
current_text, No triggering condition is present.
LAKA
- Smallest sufficient intervention
- Yes
- Primary axes

Other syntax rules
- SYN-001 Complete clause for formal prose IF a unit is presented as a formal prose sentence AND lacks an independent clause, THEN attach it, complete it, or label it as a fragment ELSE retain. Hard constraint
- SYN-002 Separate fused independent clauses IF adjacent independent clauses have no valid boundary, THEN add a coordinator and punctuation, a semicolon, or a period ELSE retain. Hard constraint
- SYN-003 Prefer visible actor–action order IF the reader must act or identify responsibility AND no stronger reason favors passive voice, THEN place the actor before the action ELSE retain. Context default
- SYN-004 Use passive voice for a reason IF a clause is passive, THEN retain it only when the receiver is the topic, the actor is unknown or irrelevant, blame should be softened, or domain convention requires it ELSE convert to active. Context default
- SYN-005 Put conditions before instructions IF an instruction applies only under a condition, THEN state the condition before the imperative ELSE give the action directly. Context default
- SYN-006 One principal action per procedural step IF a step contains multiple independently verifiable actions, THEN split them into ordered steps ELSE retain a tightly coupled action. Context default
- SYN-007 Limit nested clauses for general audiences IF clause nesting exceeds two levels AND the audience is not expert-only, THEN split or promote a buried clause ELSE retain necessary complexity. Heuristic
- SYN-009 End-weight complex material IF a long complex phrase separates subject from verb OR delays the core relation, THEN move that weight later when meaning permits ELSE retain. Heuristic
