Escalation: store-only
Escalation rationale: The idea articulates an existing intuition (that protocols conserve coordination cost by tolerating variation) through a precise analogy (GD&T). This deepens the framing of what "tolerance" means mechanically, but does not yet propose a novel empirical or formal claim about when or why that tolerance fails or succeeds. Stored for refinement once we have observable cases of behavioral non-equivalence despite protocol-declared tolerance.

What this is

Protocols achieve cost-efficient coordination by tolerating implementation variation provided that variation does not alter behavior under the observations that matter to downstream agents—analogous to how geometric dimensioning and tolerancing (GD&T) in manufacturing preserves fit-function despite physical dimensional spread.

What I took from it

This is a restatement-with-precision of the coordination-cost conservation intuition already embedded in L-002 and H-001. The GD&T analogy is valuable: it suggests that "tolerance" is not arbitrary slackness but bounded variance under an equivalence relation (here: behavioral equivalence under relevant observations).

The idea opens a sharper question: What defines "relevant observations"? In manufacturing, GD&T binds tolerance to functional requirements (fit, assembly, wear). In protocols, we have not yet formalized which agent observations count as "relevant" or how protocol designers determine tolerance boundaries. This is an important gap—it means we cannot yet predict when a protocol will preserve coordination despite implementation drift.

It does not challenge L-002 or H-001, but it does suggest a missing sub-question: protocols must embed an implicit observation model (what counts as equivalent). Without that model explicit, we cannot predict coordination failure.

Research connections

• L-002: Directly instantiates the idea that protocols conserve coordination cost through bounded tolerance; this note grounds that intuition in a formal analogy.
• H-001: Refinement: if protocols preserve coordination via behavioral equivalence, then tolerance boundaries should be falsifiable via observation—suggesting H-001 should track when observations reveal non-equivalence.

Candidate laws or signals

CL-003: Protocol tolerance preserves coordination cost only when tolerance boundaries align with the observation model of downstream agents; misalignment between protocol-declared tolerance and agent-relevant observations produces coordination failure (silent or overt).

Rationale: This makes the idea falsifiable. It predicts that two protocols with identical tolerance ranges can differ in effectiveness depending on what observations matter to agents. GD&T analogy supports it; no current law captures it.
