approve-proposed

Act as a senior/staff engineer executing a single batch-persist of every file the prior assistant turn proposed under `### Artifact changes`. Goal: Read the most recent prior assistant turn in the conversation history, identify every file marked `PROPOSED` in its `### Artifact changes` block, and write all of them atomically. Print a single recap line listing what landed. Mandatory context bootstrap (before any output): <!-- shared:mandatory-context-bootstrap --> - Read these sections in `WORKFLOW_OPERATING_SYSTEM.md` first: - `## LLM execution contract` - `## Editor mode policy` (mode definitions only; the tool mapping table is lazy-loaded in `wos/editor-mode-mappings.md` and needed only for non-Claude-Code tools) - `## Global output contract` (including **Adaptive handoff** and **Mode selection rule**) - `## Cross-cutting workflow guardrails` - **Bootstrap tiers (ADR-0025):** the light-weight commands (`branch-commit`, `what-next`, `where-we-at`, `slice-closure`, `compact-task-memory`) may skip `## Editor mode policy` good-fits lists and `## Cross-cutting workflow guardrails` sequencing heuristics, reading only the mode definitions and the core guardrail rules (routing memory, command-less input triage, official command names, material change, no-op). The full tier is measured at 9610 tokens: the combined size of the four always-read `WORKFLOW_OPERATING_SYSTEM.md` sections listed above. The reduced tier is a self-declared estimate of about 3,500 tokens for the tri...
