Specification gate: run one complete spec_guard pass for Standard/Assurance.

Implementation: classify EACH slice independently from task governance: + MECHANICAL -> worker (Luna) + SEMANTIC -> semantic_worker (Terra) + A Standard/Assurance task does not imply Terra implementation.

Review mapping: before Terra semantic_reviewer, have explorer produce a compact review map + whenever the diff is not trivially small (roughly > 4 files, > 200 changed lines, + generated/noisy changes, or AC-to-code ownership is not obvious). + 7.

Implementation - - Exactly one write-capable worker may be active in a worktree. - - Record TASK_BASE before the first task-owned commit. Treat TASK_BASE..HEAD - plus any task-owned dirty state as the implementation under review. - - For large work, assign one end-to-end vertical slice at a time to the same - worker while its context remains compact. If a slice would accumulate a large - diff before a useful checkpoint, split it into smaller independently testable - coherent slices rather than making time-based or incomplete commits. - - Every slice brief must include SLICE_ID, AC_IDS, allowed scope, frozen - invariants, explicit EXIT_CHECKS, and whether the slice is expected to form - a commit checkpoint. - - A slice is not complete while an assigned exit check is merely planned or - pending. - - After all EXIT_CHECKS pass, normally have the worker create one unsigned - commit for the completed coherent slice. Do not checkpoint incomplete, - failing, purely preparatory, or trivially tiny work that belongs with the - next coherent slice. - - Preserve the resulting commit hash as evidence. A commit is a checkpoint, - not proof of semantic correctness; later review still covers the complete - TASK_BASE..HEAD range. - - If worker context becomes dominated by prior attempts, retire it and spawn - a fresh worker with only the compact current contract and remaining slice. - - 5. Assurance milestone - - After the first end-to-end slice, run `spec_guard` again against the actual - evidence when the task is Assurance-class or the riskiest assumption was - only testable after implementation. - - The milestone gate must scan the complete affected invariant category, not - only the exact line or failure just observed. - - 6. Semantic review and repair - - Freeze the coherent TASK_BASE..HEAD diff, including all task commits, and - run one `reviewer` full pass. - - Consolidate all accepted CODE_FIX findings into one worker repair brief. - - After the repair batch passes its assigned checks, create at most one - unsigned repair commit for that batch. Do not create one commit per finding. - - After repair, re-review affected ACs plus adjacent instances of the same - invariant; do not feed findings to the worker one by one. - - DESIGN_INVALID returns to `spec_guard` rather than being patched around. - - After two failed repair attempts for the same underlying issue, stop - incremental patching and use `deep_debugger`. - - 7. Final validation - - Start `validator` only after semantic review and accepted repairs are done. - - Hand it one exact tree and a validation matrix tied to AC IDs. - - If repository CI exists, CI parity is the primary mechanical oracle unless - the contract explicitly requires additional runtime evidence. - - ESCALATE TO SOL ONLY WHEN: - - a user decision is required; - - the approved scope or user-visible behavior must change; - - security, data-loss, licensing, legal, or irreversible operational risk - requires arbitration; - - independent high-confidence agents materially disagree and targeted - evidence cannot resolve the conflict; - - authorization-sensitive Git/GitHub/external-state action is now ready; - - the task is complete or genuinely blocked. - - Do not return to Sol between ordinary phases.
