TheRON 0c220f449b ROADMAP: section 7 is binding. PRECISION: prismatic-only is a limit
ROADMAP opened by saying nothing in it is a promise. Section 7 holds eighteen standing principles cited by number as settled law from commit messages and from other documents - 4 governs what is hashed, 13 defines what a standard is, 17 governs what may write to a record, 18 governs how a contribution is admitted. A reader taking the header at its word would conclude Principle 17 is optional. The disclaimer now says what it always meant: it covers section 4 sequence and section 5 assumptions, not section 7.

Principle 5 gets the same qualification PROCESS section 8 got. A permanent deviation is the specification is right about facts on a host and would be licence to lower a REQ if read without limit.

PRECISION section 10 requires every section 7 entry to say whether it is a limit that work may lift or a boundary that was chosen. The prismatic-only entry said neither, which is the single most consequential ambiguity in the document. It is a limit, and the reason is now recorded: the oracle is a two-dimensional oracle with a scalar length multiplier - every recorded value is a property of the cross-section except LENGTH_MM, VOLUME_MM3 and MASS_G, and volume equals rounded section area times length to within 3.6e-12 across all 113 accepted cases. Lift it carelessly and that relation stops holding; nothing fails, it just stops meaning what it means. Anything keeping each station two-dimensional preserves it.

Also in PRECISION: STL export landed and is no longer planned. An absent export format is a limit; the refusal to emit toolpaths is a boundary.

ROADMAP section 4a corrected to match STAGING-STATE section 3a: nothing here is implemented on Kane Fabric, and SASE was used and never defined. The port is recorded done. The seed commit and test count are removed as derivable.

IDENTITY-CONTRACT: the rewrap owed from a76879f.

Applied by anchored patcher. Suite 643 passed, oracle intact. Documentation only.
