Fixes #3654.

Claude Code writes api-request-blob records in its transcript. Each record repeats the blocks of one message of an API request: the prompt, the tool calls, and the tool results. The spec copy finders of the Claude Code provider did not handle these records:

• The copies of pasted images and spec sources in the records stayed inline, so the evidence held them a second time.
• A record repeats the tool call ID of its entry. When a record came after its entry, the finder used the record in place of the entry, so the entry kept its copy.

The finders now skip the request blobs when they match calls and results. Then each blob block gets the pointer of the entry with the same tool call ID, when it holds the same value. An image in a blob gets a pointer when its data is a spec source. The Trace README notes that pointers also cover these records.

The end-to-end suite found the problem (spec issue-3635, #3655). With this fix, its "Pasted image pointers" check passes for Claude Code, and "Spec source pointers" passes in 3 of 3 runs (it was 2 of 3).

AI disclosure: Claude Code helped to write this change.

Change Summary

• Adds Claude api-request-blob replacement logic so pasted-image and spec-source copies reuse stored pointers.
• Updates spec-copy matching to ignore blob lines during entry/result matching and preserve non-identical blob content.
• Adds focused request-blob tests and updates the Trace README row for spec source pointers.

AI Session Overall Score

🟢 89% — Focused fix, verified well, but the user never explicitly confirmed the result.

🟢 93% · solution-quality

🟢 Root-cause fix skips blob records during matching and only reuses pointers for identical JSON. · High Impact

🟢 92% · alignment

No notes.

🟢 92% · context-and-planning

🟢 The opening scope narrowed the large spec to local-only, happy-path, Claude-first work. · High Impact

🟡 78% · verification

🟢 New tests cover copied reads, writes, pasted images, and divergent blob content. · High Impact

🟠 No explicit user confirmation of the repaired behavior appeared before the session pivoted to SAST follow-up. · Medium Severity

💡 Before switching tasks, ask for or show one concrete confirmation of the repaired behavior.

🟡 Nightly, Slack, and multi-provider acceptance checks from the original spec are still parked for later milestones. · Low Severity
