test(epoch002): characterize materialization repository event gates on current main

[ndrorchestration]

Purpose

Reconstruct the test-only Track A Epoch 002 materialization repository-event characterization directly on current protected main after #721 advanced the accepted base.

This is coverage hardening only. It does not modify production materialization code, schemas, workflows, custody, evidence, authorization, or scientific state.

What is characterized

The tests directly exercise already-implemented production event gates for:

• one-parent / one-file creation-only materialization evidence admission;
• rejection of evidence replay over a pre-existing canonical path;
• one-parent / one-file creation-only MATERIALIZATION_RECEIPT creation;
• direct evidence-admission → receipt succession;
• rejection of an intervening commit between evidence admission and receipt;
• rejection of receipt replay over a pre-existing canonical receipt.

No production semantics are changed to satisfy these tests.

#723 provenance

Draft #723 first exposed the coverage gap and then produced positive dedicated materialization validation. Its initial Python workflow failed only because Black required three conditional lambdas to be formatted; that formatting-only defect was corrected at head 816d7b830cb0ee428d73197b15b4fd1fccdecd4b, after which fresh Python and the dedicated materialization workflow completed SUCCESS. #721 subsequently advanced protected main, making #723 stale. #723 is closed and retained as validation provenance only. No #723 acceptance evidence transfers.

Fresh exact-head verification

Exact current-base head 768b18f160903dade165d862befcb769cf391645 now has 19/19 returned pull-request workflow families completed SUCCESS:

• Python Tests & Quality Checks
• Track A Epoch 002 Materialization Receipt
• Governance CI
• PDMAL Pre-Freeze Runner Validation
• PDMAL Harness Validation
• PPTL CI
• DGAF Regression Suite
• Truth Layer Tests
• Truth Layer Validation
• Epistemic Evidence Validation
• Full Repository Coverage Audit
• Critical PR Lane Custody
• Control-State Consistency
• Validate Control-State HEAD Binding
• Claim Hygiene Audit
• IP Hygiene Sweep
• Vocabulary Translation Matrix
• Propagation Consistency (Advisory)
• PR Issue-State Keyword Guard on the pre-final-description metadata state

Because this body update changes PR metadata, the PR Issue-State Keyword Guard must rerun and complete SUCCESS before this PR is marked ready. No pre-update guard result is transferred across that metadata change.

Explicit non-effects

No real materialization occurs. No empirical or protected artifact is read. No custody secret, mapping, materialization evidence instance, repository materialization receipt, analysis authorization, or result is created.

Current boundary remains:

DATASET_LOCK = ESTABLISHED
BOUNDED_UNBLINDING = AUTHORIZED
MATERIALIZATION = NOT_ESTABLISHED
MATERIALIZATION_RECEIPT = NOT_ESTABLISHED
PRIMARY_ANALYSIS = NOT_AUTHORIZED / NOT RUN
SCIENTIFIC_N_INCREMENT = 0
CANONICAL_DGAF_EFFICACY = NOT_ESTABLISHED
INDEPENDENT_VALIDATION = NOT_ESTABLISHED
HIGH_ASSURANCE = PRE-FREEZE / FAIL-CLOSED / NOT AUTHORIZED / N=0
