Build a Strategy Mosaic model from scratch

This skill is the execution layer for Mosaic data-model creation and modification. The planning layer is skills/strategy-data-modeling/SKILL.md — route through it first unless the user gave you a complete pre-planned build.

Out of scope for this skill — route to skills/strategy-automation/SKILL.md and memory/reference_strategy_surface_matrix.md:

• Classic / project semantic-layer objects (legacy attributes, project metrics/facts/filters, project security filters)
• Runtime analytics (reports, dashboards, documents, prompt answers, exports)
• AI / Agent / Bot work
• Non-Mosaic cube / dataset work (Intelligent Cube, OLAP cube, Super Cube, MTDI, Push Data)
• Subscriptions, users, groups, roles, VLDB, object administration

Load these memory files on entry

Every one of these owns a piece of the build surface; this skill delegates the detail to them. Load before synthesizing any payload.

• memory/reference_strategy_error_codes.md — grep this FIRST on any 4xx/5xx before looking anywhere else.
• memory/reference_data_modeling_foundations.md — Kimball: grain, conformed dims, star/snowflake/galaxy/bridge topology, additivity classes.
• memory/reference_mosaic_business_logic_translation.md — intent → build plan; the mandatory pre-build artifact.
• memory/feedback_business_logic_pass_mandatory.md — non-optional rule.
• memory/feedback_mosaic_relationship_wiring.md — conformed-dim recipe + the 8004ccdb / 8004ccc7 / 8004e409 failure modes + fix pattern.
• memory/feedback_build_mosaic_session_leak.md — one-session-one-process rule; the single most common cause of mid-build failure.
• memory/reference_mosaic_rest_api.md — verified endpoint paths (auth, datasources, catalog, data models, changesets, security, translations).
• memory/reference_mosaic_modeling_concepts.md — payload shapes for attributes, metrics (compound / conditional / level / transformation), relationships, filters, transformations.
• memory/reference_mosaic_publish_path.md — the one publish file: 3-step flow, do-not-fire-both rule, dataType publish-readiness gate (prevents iServerCode -2147212544 stalls).
• memory/reference_mosaic_vs_legacy_surfaces.md — subType 779 vs 776 classification before any publish/refresh/execute write.
• memory/reference_strategy_object_cloning.md — clone-and-remap procedure when a payload shape is unknown.
• memory/feedback_mosaic_ship_bar.md — ship-bar checklist: naming, DESC-form report/browse displays, metric format tokens, description length cap, SF naming.
