Unicode Boundary Bones

What this snack represents

Chewable public-output safety for glyphs with suspicious pockets. A validation bone for rejecting private-use code points, unsupported controls, and hidden-codebook bait.

Plain English: Unicode boundary checks prevent public widgets from treating private or unsafe input as interpretable public symbols.

Formula: 10m normalization + 15m private-use scan + 15m publicOutputEligible check + 15m no-op response

What this teaches: Unicode Boundary, publicOutputEligible, No-Op Dominance.

Why teams underestimate it

The shelf label works because the cost is usually hidden across clarification, review, context switching, QA, and follow-up decisions. BarkBowl makes those ingredients visible before the work is treated as free.

Time formula

10m normalization + 15m private-use scan + 15m publicOutputEligible check + 15m no-op response

Worked example

One serving of Unicode Boundary Bones is currently modeled at 55 minutes, or 0.92 person-hours. Multiply servings when the work repeats, spreads across more people, or needs another review cycle.

Warning label

Rejects inputs that try to leave the public kennel.

Evidence needed

Before committing this snack, collect an owner, a reason, a time formula, a rollback or no-op alternative, and a short explanation of what the receipt does and does not prove.

How to reduce the cost

Bounded Gloss Chews

No-op alternative

If evidence, authority, or capacity is missing, the mature move may be to record a no-op decision and revisit when the missing ingredient exists.
