chore: sync public mirror from internal

[evalops-mirror]

Summary

• sync the sanitized public tree from dx-corp/mono
• keep dx-corp/code as a generated public mirror of the private source of truth
• preserve public-owned CI and trusted-publishing workflows from the public checkout
• internal source SHA: d86f17d9fc24cbabd645f27a7dbc3d861d57acb7
• last generated public sync base: 9610ff4cc0f57cd58d5d334d46b875b766f6b2e2
• previewed public-tree drift: 2 file(s) to copy/update and 0 stale file(s) to delete
• public-only commits since last generated sync: 0
• to pause generated syncs while hand-editing this branch, apply the sync-hold label to this PR; the sync workflow skips every push while it is set

Source-of-truth status

Projection: deixic-code

• Source: dx-corp/mono@d86f17d9fc24cbabd645f27a7dbc3d861d57acb7

• Prior destination base: 9610ff4

• Content SHA-256: bf569f56d06fbd6cd2c5de9cd3b3d699dbc019417492e2493ec4da8b9ab6202e

• Result: drift_detected; 2 changed, 0 deleted

• Destination-owned content is preserved. Destination CI is a separate health signal.

• copy/update .repository-projection.json

• copy/update proto/maestro/v1/protocol-compatibility-manifest.json

Drift sample

• copy/update .repository-projection.json
• copy/update proto/maestro/v1/protocol-compatibility-manifest.json

Public-only commits since last generated sync

• none detected since last generated sync

Validation

• generated by the sync-public-release-mirror workflow in public-tree mode

Test Plan

• generated by the maestro-sync-public-release-mirror workflow in public-tree mode
• public-source-provenance require-internal-pr confirms internal source PR lineage
• generated mirror PRs use the slim public CI path (fmt/clippy/smoke + provenance); full cargo test/evals already ran on internal main for this SHA
• bot review threads on generated mirror PRs are advisory and do not block the next sync update

Staged Rollout

• Staging is unnecessary for this generated mirror PR: it does not independently promote user-visible behavior. It mirrors already-reviewed internal source from dx-corp/mono@d86f17d9fc24cbabd645f27a7dbc3d861d57acb7, including existing hidden/evaluation surfaces, and keeps public package parity behind the established public-source-provenance gate.
