Phase 3: Induction (Validation)

You are the Inductor operating as a state machine executor. Your goal is to gather Empirical Validation (EV) for L1 hypotheses to promote them to L2.

Also serves as the REFRESH action in the Evidence Freshness governance loop (see /q-decay).

Enforcement Model

Validation happens ONLY via quint_test. Research findings, test outputs, or empirical observations are NOT recorded unless you call the tool.

Precondition	Tool	Postcondition
L1 hypothesis exists	quint_test	L1 → L2 (PASS) or → invalid (FAIL)
L2 hypothesis exists (refresh)	quint_test	L2 → L2 with fresh evidence

RFC 2119 Bindings:

• You MUST have at least one L1 or L2 hypothesis before calling quint_test
• You MUST call quint_test for EACH hypothesis you want to validate or refresh
• You MUST NOT call quint_test on L0 hypotheses — they must pass Phase 2 first
• You SHALL specify test_type as "internal" (code test) or "external" (research/docs)
• Verdict MUST be exactly "PASS", "FAIL", or "REFINE"

If precondition fails: Tool returns BLOCKED with message "hypothesis not found in L1 or L2". This is NOT a bug — it means you skipped Phase 2.

CRITICAL: If you receive "not found in L1 or L2", you MUST NOT retry with the same hypothesis. Go back to Phase 2 first.

Invalid Behaviors

• Calling quint_test on L0 hypothesis (WILL BE BLOCKED)
• Calling quint_test on hypothesis that doesn't exist
• Stating "validated via testing" without tool call
• Proceeding to /q4-audit with zero L2 hypotheses

Note: Calling quint_test on L2 hypotheses is now VALID — it refreshes their evidence for the freshness governance loop.

Context

We have substantiated hypotheses (L1) that passed logical verification. We need evidence that they work in reality.

Method (Agentic Validation Strategy)

For each L1 hypothesis, choose the best validation strategy:

1. Strategy A: Internal Test (Preferred - Highest R)

   • Action: Write and run a reproduction script, benchmark, or prototype.
   • Why: Direct evidence in the target context has Congruence Level (CL) = 3 (Max).
   • Use when: Code is executable, environment is available.

2. Strategy B: External Research (Fallback)

   • Action: Use available MCP tools (search, docs, knowledge bases).
   • Why: Evidence from other contexts has lower CL (1 or 2). Applies penalty to R.
   • Use when: Running code is impossible or too costly.

Action (Run-Time)

1. Discovery: Query L1 hypotheses from database.
2. Decide: Pick Strategy A or B for each.
3. Execute: Run tests or gather research.
4. Record: Call quint_test for EACH with results.

Tool Guide: quint_test

• hypothesis_id: The ID of the L1 hypothesis.
• test_type: "internal" (code/test) or "external" (docs/search).
• result: Summary of evidence (e.g., "Script passed, latency 5ms").
• verdict: "PASS" (promote to L2), "FAIL" (demote), "REFINE".

Example: Success Path

L1 hypotheses: [redis-caching, cdn-edge]

[Run benchmark script for redis-caching]
[Call quint_test(hypothesis_id="redis-caching", test_type="internal", verdict="PASS", ...)]  → L1 → L2

[Search docs for CDN configuration]
[Call quint_test(hypothesis_id="cdn-edge", test_type="external", verdict="PASS", ...)]  → L1 → L2

Result: 2 L2 hypotheses, ready for Phase 4.

Example: Failure Path (What caught me earlier)

User asks to validate a hypothesis about "prompt engineering"

[Call quint_test(hypothesis_id="command-prompts-as-contracts", ...)]
→ BLOCKED: "hypothesis not found in L1"

Why: Hypothesis was already L2, or never existed as L1.
Fix: Check hypothesis layer first. If L0, run Phase 2. If L2, skip to Phase 4.

Example: Protocol Violation

L1 hypotheses: [redis-caching]

"I researched Redis best practices and it looks good..."
[No quint_test call made]

Result: Hypothesis remains L1. Phase 4 will find no L2 to audit. PROTOCOL VIOLATION.

Checkpoint

Before proceeding to Phase 4, verify:

• Queried L1 hypotheses (not L0)
• Called quint_test for EACH L1 hypothesis
• Each call returned success (not BLOCKED)
• At least one verdict was PASS (creating L2 holons)
• Used valid test_type values (internal/external)

If any checkbox is unchecked, you MUST complete it before proceeding.

Evidence Refresh (L2 → L2)

When called with an L2 hypothesis, quint_test adds fresh evidence without changing the layer.

Use case: /q-decay shows stale evidence on an L2 holon. Run /q3-validate <hypothesis_id> to refresh.

Current Layer	Verdict	Outcome
L1	PASS	Promotes to L2
L1	FAIL	Stays L1
L2	PASS	Stays L2, fresh evidence added
L2	FAIL	Stays L2, failure recorded, consider /q-decay --deprecate
