From aa57d8589c415b3ce53b29b9ac503397d267064c Mon Sep 17 00:00:00 2001 From: robbond Date: Fri, 9 Oct 2026 14:29:08 +0100 Subject: [PATCH] feat(confidence-engine): verify disk persistence of focused-investigation evidence serializer (Experiment 7, Iteration 7) Extended deterministic test to write serialized evidence record to OS temp directory, read back from disk, parse JSON, and assert deep structural equality. Verified: five structured arrays preserved with correct lengths; exact inputs unchanged; identity fields intact; null metadata fields survive round-trip. Temp file cleaned in finally block. Zero live model calls. Zero browser calls. No production code or canonical-helper modifications. Experiment 4 original structured output remains unavailable.

Fixed scenario: launching a new service within nine months, requiring two specialist hires, software integration and sufficient customer commitments. Target node `n2yzwlv`: "Timeline and feasibility of recruiting two specialists within the nine-month window." Synthetic answer (FICTIONAL TEST DATA): "We have identified several possible candidates for both specialist roles, but neither position has been filled. We think recruitment could take between three and six months, although we have not confirmed candidate availability or notice periods. Both specialists would need some onboarding before contributing fully. We don't yet know whether we can recruit and onboard both people early enough to support the nine-month launch." The generated question was supplied explicitly as `previousQuestion` via `composeDeepInvestigationCheckpoint()`. Model: `qwen-claude:latest` (Ollama). Exactly one live LLM call. Result: **PARTIAL** semantic fidelity. The model correctly preserved the core uncertainty about whether recruitment can be completed within the nine-month window and correctly distinguished estimates from confirmed timing, possible candidates from secured hires, and expected onboarding from completed onboarding. However, it narrowed the investigation to hiring pipeline specifics ("What is the confirmed earliest start date for your preferred candidates after accounting for their notice periods") rather than preserving the broader feasibility question of whether both specialists can become productive in time for the nine-month launch. The strongest counterevidence: the canonical description "Timeline and feasibility" was reduced to essentially a recruitment logistics investigation, losing the broader cross-area dependency and cascading-delay uncertainty captured in the original HS-03C graph (`unexplainedTransitions` with ID `utrans_dependency`). This is consistent with the HS-03C partial pattern from prior experiments. Input provenance: synthetic answer deliberately crafted for this controlled experiment, not a real user response. Graph constructed from HS-03C reconstruction fixture (`.evidence-temp/headless-semantic/HS-03C-result.json`). - **Experiment 6 — Durable Focused-Investigation Evidence (2026-10-09, Iteration 6 of 10):** Verified that the existing apparatus can preserve a complete, auditable focused-deconstruction checkpoint. Added `serializeFocusedInvestigationEvidence()` to the canonical helper (`tests/graph/live-update-experiment-helper.cjs`). Pure function accepts a completed checkpoint + identity/metadata params and returns JSON-serializable evidence record: (1) five deconstruction arrays preserved verbatim — `observations`, `uncertainties`, `assumptions`, `relationships`, `possibleFollowUpQuestions`; (2) exact inputs — `canonicalTargetDescription`, `actualQuestion`, `exactAnswer`; (3) execution metadata — null for fields not exposed by the apparatus. Deterministic verification: syntax check passed, 79/79 assertions passed including 28 new evidence-ser tests. No production code modified. No live LLM calls. No new semantic evidence produced. Experiment 4's missing structured output still cannot be reconstructed (never persisted by the apparatus at that time). Evidence-capture limitation corrected for future experiments. + +- **Experiment 7 — Durable Focused-Investigation Disk Persistence (2026-10-09, Iteration 7 of 10):** Verified that `serializeFocusedInvestigationEvidence()` output survives write-to-disk and read-back without loss.
