Re-measured the Option-E prototype's reported figures against CONTEXT.md on
next (2026-07-31) and recorded the delta rather than overwriting the June
numbers:
- index counts 393/18 (2026-06-24) -> 416/20 today; CONTEXT.md gained the
PROBE (11) and PROHIB (10) classes
- of the 3 duplicate predicate IDs, only RULESET.WORKFLOW_MARKDOWN.FENCES
remains; the two RULESET.GEMINI.* went with the Gemini runtime removal
- gen-context-index.cjs --check exits 1 on next, so Phase 0's "--check green
in CI" criterion is unmet (invisible to CI: the example sits outside tests/)
Adds Open question 4 (index keyed on baked line numbers re-drifts on any
CONTEXT.md line shift, which matters once Phase 1 promotes --check to a CI
gate), and records the reviewer-proposed eval-gate question as resolved by
the PROBE.*/PROHIB.* predicate classes (ADR-550 D4/D7, ADR-1606).
Also names both surfaces of the Windsurf 12 KB throw in Decision 2, since it
is duplicated byte-identically in bin/install.js and
src/runtime-artifact-conversion.cts.
Docs-only. No code, no runtime-loaded text, no behavior change.

Phase 0 of the Dynamic Context Management epic (#1671): the ADR (documentation) plus a non-shipping reference example under examples/dynamic-context-management/ — the Option-E predicate fact-store parser/selector, a self-contained --check/--write/--select index generator, a sample index, and a runnable demo.
The example is intentionally excluded from the build (src/->bin/lib/), the npm package files[], the installer, and the CI test suite (tests/) — nothing here is compiled into or installed with GSD. Production implementation lands in a later phase.
