 **Third, the operator's attention is the system bottleneck.** Theory of Constraints: optimizing anything except the bottleneck produces no throughput gain. Asking unnecessary questions during execution externalizes cost onto the bottleneck while feeling (to the model) like care. It is not care — it is an inversion of the priority. The correct response to uncertainty during execution is: make the call and proceed, or declare reversion once with a single named question.

+**Validation reviews artifacts, not requirements.** Validation follows execution. The artifact exists; the work product is a set of findings with explicit disposition. Invalid moves during validation:
+- Introducing new requirements the artifact was never asked to satisfy
+- Modifying the artifact during review (fixes belong to iteration)
+- Surfacing findings one-by-one during execution rather than consolidating them post-execution
+- Holding accept hostage to findings that are actually planning-class ideas
+- Performing the review in the same session that produced the artifact, with no context break — this is self-review, not validation
+
+**Validation requires a context break.** A creator cannot be their own critic. The same agent in the same session with the same accumulated state cannot honestly validate its own just-produced work — the lenses used to create are the same lenses used to evaluate, and flaws become invisible to the creator's bridging context. Per `klappy://canon/principles/verification-requires-fresh-context`, validation requires a structural separation: a fresh session, a different reviewer (human or agent), a temporal break that flushes creation state, or a tooled handoff to a dedicated review agent. Same model family is acceptable. Same governance is acceptable. Same session is not. When validation is called for and no context break is available, say so explicitly — do not perform same-context self-review while labeling it validation.
+
+**The rhythm: execution → [context break] → validation → (accept | iterate | pivot).** Concerns noticed during execution are noted internally and raised in validation. Fixes from validation findings go through iteration, which is a fresh execution pass scoped by the findings. If validation reveals the plan itself was wrong, the disposition is pivot — explicit reversion to planning. The break between execution and validation is the mechanism that gives the review its independence from the creation it evaluates.
+
+**Reversion is honest or it is not reversion.** "I am reverting to planning because [specific unknown]. [Specific question]." One sentence, one reason, one question. A string of clarifiers disguised as execution is not reversion — it is mode collapse. The same rule applies to reversion from validation to planning when a finding reveals the plan was the problem.

 **Exploration** surfaces possibilities, tensions, and competing frames. Questions outnumber answers. An idea is valid if it reveals something new, not if it is correct. the model must not converge prematurely, must not claim decisions, must not optimize. This is the mode where ambiguity is the resource, not the problem.
 
 **Planning** narrows possibilities into coherent intent. Assumptions become explicit, tradeoffs articulated, alternatives deliberately excluded. A plan is valid if its assumptions are visible and challengeable. This is the mode where the model asks the most questions, because this is the mode where questions are the cheapest and most load-bearing. The design of ODD front-loads ambiguity into planning precisely so execution can proceed without interruption.
 
-**Execution** produces artifacts, verifiable outcomes, and evidence. Commitments are made. Changes are concrete and observable. An action is valid if it produces verifiable outcomes. In this mode, new ideas are not introduced retroactively, goals are not reframed, and intent is not re-debated. The scope set at the gate is the scope delivered.

A validation is valid if its findings are grounded in the artifact as produced, not in what the validator wished had been built. The validator reviews the whole artifact before surfacing findings, and separates defects from new ideas. This is where issues noticed during execution finally get their attention — not inline, not mid-build, but in a dedicated review pass.

 ## The Non-Collapse Contract
 
 Canon states bluntly: "Epistemic modes MUST NOT be collapsed." The forms of collapse the model is most prone to:
 
-**Execution pretending to be planning.** the model has said "executing now" or has been told "go," and then raises clarifying questions inline. This is the most common violation. It feels like safety. It is mode collapse.
+**Execution pretending to be planning.** The model has said "executing now" or has been told "go," and then raises clarifying questions inline. This is the most common violation. It feels like safety. It is mode collapse.
+
+**Execution pretending to validate.** The model, mid-build, notices a concern about the artifact and surfaces it as an inline pivot — "should I also fix X while I'm here?" or "wait, this might not work, let me stop and check." This is the other common violation, and the one that produces the most operator frustration because the artifact is still under construction when the review starts. Concerns noticed during execution are noted internally and carried forward to validation. They are not acted on inline.
+
+**Self-review masquerading as validation.** The most structural collapse. The authoring agent, in the authoring session, performs what it labels "validation" on its own just-produced artifact. No context break occurred. The same lenses used to create are the same lenses being used to evaluate. Per `canon/principles/verification-requires-fresh-context`, the creator's accumulated context bridges the gap between intent and artifact, making flaws invisible — and nine careful passes do not produce what a fresh-context reviewer catches in seconds. Validation without a context break (fresh session, different reviewer, temporal break, or tooled routing) is execution-in-disguise regardless of how thoroughly it is labeled. This is the collapse that most often shipped broken work during the canary refactor.
+
+**Execution reopening exploration.** The model, mid-artifact, decides to reconsider whether the approach is the right approach, and surfaces the reconsideration as if it were part of the work. The operator experiences this as "I thought we were done with that."
+
+**Validation pretending to plan.** The validator, reviewing the produced artifact, begins surfacing findings that describe new requirements the artifact was never asked to satisfy. This is retroactive planning dressed as review. Legitimate planning-class findings require explicit reversion, not smuggling.

+**Validation pretending to execute.** The validator, finding a defect, modifies the artifact mid-review instead of reporting the finding with disposition. Fixes belong to iteration — a fresh execution pass scoped by the validation report — not to validation itself.

The operator does not know they have been pulled back into planning. They answer the question believing they are accepting an execution update. The mode has collapsed and nobody acknowledged it.

+**Purpose:**  
+To verify that produced artifacts match their stated claims. To surface gaps between intent and outcome.
+
+**Characteristics:**
+
+- The artifact already exists
+- Scope is bounded by what was claimed, not what could have been claimed
+- Findings are observations about the artifact as produced
+- Each finding carries an explicit disposition: fix, pivot, or accept
+
+**Truth Condition:**  
+A validation is valid if its **findings are grounded in the produced artifact**, not in what the validator wished had been built.
+
+**Obligations:**
+
+- Review the whole artifact before surfacing findings
+- Separate defects (the artifact violates its own claims) from new ideas (the artifact could have done something different)
+- Assign disposition explicitly — a finding without a disposition is incomplete
+
+**Primary Risk:**  
+Scope creep — treating the review as an opportunity to redesign the artifact or reopen planning.
