Add hash-bound SEC cell patch preview

[YuzeJ21]

Summary

• add a pure inspection-only projector for the reviewed AAPL and AMD revenue and filing-date cells
• require exact SEC packet, canonical CSV, and repository HEAD preconditions
• prove zero schema expansion, stable row order, and unchanged unrelated cells, rows, and columns
• add a no-write Make launcher with no apply, readiness, materialization, or provider path

Verification

• 134 complete affected tests passed
• Ruff and diff hygiene passed
• independent review: Critical 0, Important 0, Minor 0
• protected main paths: 7,315 of 7,315 byte-identical
• post-commit packet deterministic across two runs

Boundaries

• canonical_apply_authorized=false
• no canonical or staged data write
• no readiness rebuild or materialization
• no source-rights expansion or provider fallback
• research workflow only

Require the reviewed repository hash

When the checkout has moved since the SEC packet was reviewed, this launcher substitutes the new git rev-parse HEAD value and the Python code only validates its format, so the command succeeds and records the drifted commit as if it were a satisfied precondition. This defeats the advertised hash-bound, fail-closed behavior and could let an owner approve cells projected by unreviewed code; require an externally supplied expected repository hash and compare it with the actual HEAD instead.
