Description

Explore and formalize a robust Google Sheets architecture for project tracking, centered on a single master index and synchronized derived views.

Reviewed a master-index pattern keyed by stable project IDs to avoid duplicated editable rows across multiple tabs.
Evaluated a controlled migration plan for splitting a monolithic control sheet into role-specific tabs while minimizing risk.
Captured a handoff memo for the Control Tower refactor, emphasizing front_registry as the canonical identity source.
Reflected on the next bottleneck after structural cleanup: maintainer cadence, staff-like spawning rules, and turning state into a prepared brief.
Considered a manual field study approach to observe self-maintenance workflows and extract reusable routines, support artifacts, and automation rules.
Applied a front-compression sweep concept to triage projects into a small set of truthful carry states and support needs.
Reinforced the principle of archive over deletion to preserve referential stability in spreadsheet-based systems.

Clarified the core design decision: identity should live in one canonical registry, while other sheets should be formula-driven or lookup-based derived views.
Established a low-risk migration sequence: freeze sheet roles, move unambiguous fields first, keep ambiguous fields in the legacy sheet, and only then derive operational views.
Identified that the main constraint is shifting from data-structure cleanup to operational cadence and maintenance loops.
Consolidated a consistent spreadsheet governance model: stable IDs, soft-delete/archive states, and derived sheets filtered by status rather than row position.

Execute the controlled split of the Control Tower sheet into partial role-specific tabs.
Build the derived operating view once the structural migration is complete.
Run a one-week observation of maintainer-style interventions to derive automation targets and support artifact templates.
Define the first concrete spawn rules and maintainer routines from the manual field study.
Convert the front-compression triage into a repeatable review workflow.
