Sandwich Hime

Work from the repository root. Treat .sando as Sandwich Hime templates and .san exclusively as source for the separate San language.

Inspect before acting

1. Read go.mod; record the exact gamertan.com/sandwich-hime/sando version.
2. Inspect adjacent .sando.go headers for compiler version, runtime ABI, and source digest. Never hand-edit generated files.
3. Run himesan version --json. Require a compatible runtime ABI and preserve every pinned version. Never substitute @latest or silently update a module.
4. Read references/authoring.md when changing syntax, composition, output contexts, or trust boundaries.
5. Read references/workflows.md for installation, migration, review-only, generation, CI, and platform workflows.

Choose the workflow

• For review, diagnosis, or security work, run himesan check --json only. Do not write unless the user authorizes changes.
• For authorized template changes, edit .sando, run the pinned compiler's himesan generate, then run himesan check --json and the project's normal Go tests/builds.
• Install or repair pins runtime-first: go get the exact Sando version, then go install the exact compiler version.
• Use typed component functions and <?~ Component(...) ?> composition. Do not invent an inheritance, block, or implicit-layout framework.
• Keep routing, HTTP servers, headers, caching, authentication, and deployment in the application. Sandwich Hime compiles templates; it does not own them.

Enforce security boundaries

• Treat static template markup and Go code as trusted project source.
• Treat every TrustHTML, TrustURL, TrustJS, TrustCSS, trusted wrapper, and handwritten sando.Component as an explicit output capability. Audit its provenance and any HTML-parser-state effect.
• Preserve contextual escaping. Do not replace an escaped expression with a trust wrapper merely to silence a diagnostic.
• Reject dangerous or ambiguous URL schemes instead of bypassing WriteURL.
• Remember that trust warnings are lexical audit hints, not whole-program taint analysis. Inspect helper functions and call sites manually.
• Never execute himesan dev in an untrusted repository. It builds and starts the repository's Go program. Prefer read-only inspection and check --json.

Report the result

State the compiler version, runtime pin and ABI, commands run, generated files changed, normal Go validation run, and any remaining trust or compatibility limits.
