## What
Round-3 Gas City doctrine sweep — **docs/ slice** (user-facing operator
instructions) (**ag-r6g1**). Four docs told the reader to *"point the
reference Gas City at the repo"* to run the loop out of session;
re-narrated to the canonical substrate **NTM + MCP + managed-agents**
per [`docs/3.0.md`](docs/3.0.md).
## Surfaces (4 files, +14 −14)
- `docs/agentops-3-youtube-starter-series.md` — out-of-session demo beat
+ measurement field.
- `docs/wiki-for-agents.md` — the always-on compounding line.
- `docs/CI-CD.md` — the unattended-Dream line +
scheduled-private-Dream-runs section (dropped the Gas-City-specific
`city.toml`/`packs/`/`exec` Order mechanics).
- `docs/agentops-3-pmf-evidence-loop.md` — out-of-session step +
engagement checklist.
## Scope (sprawl-controlled)
Triaged to **live present-tense operator instructions only**. Left
already-correct architectural "ships no daemon / delegates to a
substrate" framing intact. **ag-r6g1 stays OPEN** — the operator
runbooks (`nightly-evolution`, `autonomy-runtime-cycle-1`, which carry
deeper GC-specific mayor/refinery/Order mechanics) and descriptive
comparison/example/explainer mentions are deferred to a later slice.
## Verification
- markdownlint 0 errors · `regen-all.sh --check` ALL GREEN (docs-only;
no derived-surface drift).

Rescope PRACTICE.md into PRACTICE-REGISTRY.md: it now owns only the
practice-slug lineage registry, not product positioning or CDLC doctrine.
Update all references (schema, validate-practice-citations.sh, bats test,
architecture-terms.md, documentation-index.md, aggregate.go comment).
Introduce the Context Density Rule as a canonical domain concept: every
high-value context token carries intent, boundary, evidence, decision,
constraint, or next action. New domain entry context-density-rule.md (+
codex mirror). Thread the BDD/Gherkin + DDD + Hexagonal + TDD narrow waist
through cdlc.md, README.md, PRODUCT.md, GOALS.md, and the rpi/domain/
post-mortem skills. Sync codex artifacts.
