When writing documentation or implementing algorithm/data-structure logic, make the *semantics* unambiguous: state the defining invariants/behavior, keep each section aligned to its exact step in the workflow, and avoid language-level ambiguity that can change correctness.

Apply as follows:
- **Define invariants clearly**: for data structures, explicitly state the property the structure maintains (e.g., heap parent/child ordering) and the precise rule for relationships (e.g., array parent/child indices).
- **Include operational behavior & complexity**: document the expected time complexity for the key operations (peek vs insert/delete for heaps, etc.).
- **Align section scope to the pipeline**: if the topic is a multi-step process (e.g., vector search), ensure each subsection covers the correct step (indexing/storage first; then query embedding and similarity search).
- **Eliminate correctness-impacting semantic ambiguity in code**: when equality or type-dependent logic matters (common in algorithm implementations), use strict comparisons to prevent unintended coercion.

Example (language semantics that affect algorithm correctness):
```js
// Prefer strict equality to avoid coercion-based bugs in comparisons.
if (candidate === target) {
  // correct: value and type must match
}
```

Use this standard to guide review checklists for algorithm docs and implementations so contributors don’t accidentally change meaning while only “rephrasing” or reorganizing content.
