Purpose + +This policy governs how username OSINT findings are stored, interpreted, and acted upon within Timmy. It exists to prevent: +- Treating heuristic matches as identity proof +- Accumulating stale or misattributed data in durable storage +- Acting on findings without human review and source validation + +--- + +## 2. Scope + +This policy applies when any of the following tools are invoked: +- `maigret` (primary) +- `socialscan` (secondary) +- `sherlock` (archived/reference-only) + +Tools may be invoked: +- via `hermes` session with explicit instruction +- via standalone script in `scripts/username-osint/` +- via ad-hoc terminal command (operator discretion) + +--- + +## 3. Storage boundaries + +### 3.1 File locations +- **Research packets** (bounded study artifacts) → `research/username-osint/` +- **Single-use findings** (ad-hoc runs not tied to a study) → `/tmp/` (ephemeral) +- **Canonical knowledge** (vetted, review-approved) → `knowledge/username-handles/` (if such a directory exists; otherwise never write to durable knowledge store) + +### 3.2 Naming & provenance envelope +Every saved artifact (to `research/username-osint/` or any durable location) **must** include a YAML frontmatter block: + +```yaml +--- +date: YYYY-MM-DD +tool: maigret|socialscan|sherlock # exact command line used +tool_version: +username_pattern: +sample_platforms: [github,twitter,instagram,reddit] # or "full-site-list" +status: draft|review|approved|rejected +reviewer: +provenance_notes: | + Free-text notes about rate limits, VPN usage, time-of-day, or other context + that affects reproducibility. +--- +``` + +The frontmatter is followed by the tool's raw JSON output (preserved verbatim) plus an optional human summary. + +--- + +## 4. Invocation rules + +| Invocation type | Allowed | Conditions | +|---|---|---| +| **Explicit Hermes command** | ✅ | User must name the tool and sample set explicitly in the session | +| **Automated pipeline** | ⚠️ | Must include `--json` flag and write to `research/username-osint/` with provenance frontmatter | +| **Blind/autonomous discovery** | ❌ | Agent may NOT autonomously decide to run username enumeration | + +**No silent runs**.

Platform migration, shared devices, and impersonation are common. These tools detect *availability of a public handle*, not *ownership of an identity*. + +--- + +## 6. Review & retention + +### 6.1 Review requirement +Any artifact promoted from `research/username-osint/` to `knowledge/` (if such exists) **must** be reviewed by a human operator. Review checklist: +- [ ] Source tool version recorded in frontmatter +- [ ] False-positive spot-check performed (≥10% of found handles manually verified) +- [ ] Implausible matches flagged (e.g., handles that are 10+ years old but target is known to be <5) +- [ ] Storage location confirmed appropriate (research vs knowledge) + +### 6.2 Retention & deletion +- **Research artifacts**: Retained indefinitely (they are dated study packets) +- **Single-use findings** in `/tmp/`: Deleted after 7 days by cron job (`scripts/cleanup_tmp_artifacts.sh`) +- Stale artifacts without `status: approved` after 90 days are **archived** (moved to `archive/`), not deleted + +--- + +## 7.
