test(models): custom-agent erasure leaves no uuid of the erased user in either scope by LESdylan · Pull Request #160 · Univers42/groot

LESdylan · 2026-10-26T11:18:28Z

A user's erasure must leave none of their ids in custom agents. No test proved it for both scopes, so turning custom agents on for a public surface was blocked (C314–C316).

A user is erased by two paths that never call each other: ai_erase_user and the account erasure osionos_account_erase. This PR tests both. It only adds tests; no migration changes, and neither check found a leak.

What changed

scripts/verify/ai-agents.sh check_6 runs ai_erase_user.
- The whole user-events migration needs seven feed tables, so the check extracts the real function text and applies it over a one-column ai_events stand-in. A Caveat: covers the extraction.
- It also greps the data-map rows of the account-erasure migration for the agent tables, and asserts none is keep.
models-grants.sh p5_agents_two_scope runs osionos_account_erase, against the real osionos_account_data_map.
Seed, shared by both checks: one erased user A, one kept user B, one workspace.
- A's user agent, with a create and an update in its audit.
- A workspace agent created by A and updated by B, and one created by B and updated by A.
- The workspace settings, last updated by A.
- B's own agent.
Assertions:
- No row of ai_agents, ai_agents_audit or ai_workspace_agent_settings mentions A, in any column or in before/after.
- A's user agent and its audit are gone.
- The workspace agents and their audit stay, with the tombstone in place of A.
- B's agent is byte-identical.

Evidence

Gate	Result
`sh scripts/verify/ai-agents.sh`	PASS 6 / FAIL 0
`sh scripts/verify/models-grants.sh`	RESULT: 350 passed, 0 failed (fresh and legacy)

Revert proof: removing the before scrub from ai_agents_erase_user fails both checks. check_6 reports uuidLeft=2, and models-grants drops to 348 passed, 2 failed.

What it does not prove: the scan is plain text, so an id stored encoded is invisible to it. The rows are hand-built, not written by the service.

Summary by CodeRabbit

Tests
- Expanded checks for account erasure across personal and workspace agent data, audit records, and workspace settings.
- Added validation that workspace records are retained with erased-user references removed, while unrelated users’ data remains unchanged.

…in either scope (C314-C316) Two erase paths, one assertion: after the erase no row of ai_agents, ai_agents_audit or ai_workspace_agent_settings mentions the erased user in any column or in before/after jsonb; the user-scope agent and its audit are gone; workspace agents and audit stay with the tombstone; the kept user's agent is byte-identical. - ai-agents.sh check_6: public ai_erase_user (function text extracted from osionos-user-events-migration.sql over a one-column ai_events stand-in, the whole file needs seven feed tables), plus the C314 data-map rows, none keep. - models-grants.sh p5_agents_two_scope: osionos_account_erase, with the C314 registry rows asserted against the real map. Revert proof: dropping the before scrub from ai_agents_erase_user fails both. Gates: ai-agents.sh PASS 6 / FAIL 0; models-grants.sh RESULT: 350 passed, 0 failed

Walkthrough

The verification scripts now test account erasure for user- and workspace-scoped AI agents, audit rows, and workspace settings. The checks verify deletion, UUID scrubbing, tombstones, and preservation of another user’s records.

Changes: Agent erasure verification

Layer / File(s)	Summary
Erasure checks across verification harnesses `scripts/verify/ai-agents.sh`, `scripts/verify/models-grants.sh`, `scripts/verify/models-grants/account-checks.sql`	The checks exercise the public erasure function and the transactional account-erasure path. They verify removal of user-scoped records, tombstoning of erased-user references in retained workspace records, and preservation of another user’s agent data.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Possibly related issues

Univers42/osionos#56 — The checks cover account-erasure behavior for custom-agent records and erased-user references.
Univers42/groot#124 — The checks add agent deletion coverage within the account-deletion scope.

Possibly related PRs

Univers42/groot#159 — Adds the agent tables and erasure-map rows that these checks exercise.

Merge Risk: Low · up to 8f0bb

The erasure checks are mergeable with a small coverage gap: raise the assertion floor to 15 so a missing check cannot pass unnoticed.

Set the assertion floor to 15.

p5_row treats its second argument as a minimum, not an exact count. This block runs 15 p5_ok assertions. With a floor of 14, one missing assertion can go undetected.
