docs(map): document v0.18.0 symbols + backfill migrations 060/061

Adds fable-mode, X feature-spotlight, and design-bar symbols across the map
slices (+ _complete_map mirror); backfills migrations 060 (drop_messaging) and
061 (x_feature_spotlight), both previously undocumented; corrects the ORM table
count 37->38; adds the _briefing_for include_company_goals row.

 6. **Board roadmap engine** (`ROBOCO_ROADMAP_ENGINE_ENABLED`, marker-backed, no migration): weekly one-shot PO-solo explore → `propose_roadmap` verb (PO-only, 3-7 items) → CEO per-item approve→BACKLOG. `_dispatch_roadmap_exploration` bypasses the two-reviewer board path. REVIEW: builder found+fixed a SQLAlchemy dirty-check bug (deepcopy marker before mutate); I whitelisted `create_task_from_draft` source ({prompter, roadmap}).
 
 Compose: every optional feature armed `:-true` in the NAS composes, OFF in registry; two opt-in exceptions (`CLOUD_AUTH`, `ROUTING_STRICT`) default off (change auth/failure behavior, not capability).

+## Delta 2026-07-04 — v0.18.0
+
+Three workstreams plus a migration-chain catch-up (all reviewed; all default-off except the doc-only design bar):
+
+1. **Fable mode** (`ROBOCO_FABLE_MODE_ENABLED`, default off) — opus-fable-playbook adoption on the existing model tiers (no new tier; Fable 5 is not a model option). Two levers: **doctrine** — `fable_doctrine_layer()` (`roboco/agents/factories/_base.py:203`) injects the vendored behavioral doctrine (`agents/prompts/doctrine/fable.md`) into `compose_prompt`'s layer tuple right after `base.md`. **Hooks** — `AgentOrchestrator._fable_hook_groups()` (`orchestrator.py:1414`) appends 5 vendored scripts (`docker/scripts/fable-{stop-gate,bash-discipline,honesty-nudge,prompt-nudge,precompact}-hook.sh`) AFTER RoboCo's own per-event hooks in the Claude settings.json; the grok path installs only the honesty-nudge (`write_grok_fable_hooks`/`fable_honesty_nudge_hook_config`, `roboco/llm/providers/grok_cli_config.py:308-345`) since a grok `PreToolUse`/`Stop` hook deny cancels the whole run (verified live) while `PostToolUse` never denies. Off = byte-for-byte unchanged spawn path.
+2. **X feature-spotlight** (`ROBOCO_X_FEATURE_SPOTLIGHT_ENABLED`, default off, sub-switch of `x_engine_enabled`) — a third `XEngine` origination path alongside release posts and mention replies. `Orchestrator._x_feature_spotlight_loop` opens one held exploration task for the Head of Marketing every `x_feature_spotlight_interval_seconds` (default 3d); the HoM investigates and calls the new `propose_feature_spotlight` do-verb (HoM-only, `ContentActions.propose_feature_spotlight`, `content_actions.py:1238`, role gate `_FEATURE_SPOTLIGHT_ROLES`), which materializes a held draft (`XEngine.materialize_feature_spotlight`) into the same X Post Queue as release/reply drafts. Migration 061 adds `x_seen_features` (dedup ledger) + `company_goals.brand_voice` (feeds `_voice_guide` for all three draft kinds). **Gap found (static read, not live-verified):** `propose_feature_spotlight` has no wrapper function or `_TOOLS` entry in `roboco/mcp/do_server.py` (unlike `propose_roadmap`, which has both) — `_register_tools()` only registers the intersection of the manifest's granted verbs and `_TOOLS`, so a spawned Head-of-Marketing agent cannot see this tool via MCP today despite the role-config grant.
+3. **FE/UX-UI design bar** (doc-only, no flag) — a `## Design bar` section added to `agents/prompts/teams/frontend.md` and `agents/prompts/teams/ux_ui.md` (distilled from `Leonxlnx/taste-skill`, MIT: three tuning dials — DESIGN_VARIANCE/MOTION_INTENSITY/VISUAL_DENSITY — plus typography/spacing/motion rules and an "AI tells to avoid" list), plus a pointer section in `agents/prompts/roles/developer.md` scoping it to frontend/ux_ui tasks only (backend unaffected).
+4. **Migration-chain catch-up** — `060_drop_messaging` (the comms-teardown migration: drops `messages`/`session_tasks`/`sessions`/`groups`/`channels` + 4 enum types + `journal_entries.session_id`; A2A is now the sole directed-message channel) had already landed on master but was never appended to this doc. Chain head is now **061** (this doc previously said 059); `roboco/db/tables.py` now carries **38** ORM table classes (verified via direct count), up from the 37 this doc's Purpose section stated (that figure predates 055-061 and was never recomputed).
