feat(reports): store and browse report artifacts

B001 change caused 'unsupported operand type(s) for -: list and set' during a
full consolidated scan: _db_complete_blocklist returned split_cidr_versions()
output, which is tuple[list, list], but write_blocklist_report()/blocklist_delta()
expect set operands. Return set(v4), set(v6) to match cumulative_blocklist's
contract. Reproduced the exact report path with a populated ledger and
verified it no longer crashes.

+## Blocklist behavior (cumulative / grow-only)
+
+The MikroTik `Blocked` address list is **cumulative**: it only grows over
+time and is never trimmed automatically.
+
+- An IP (or subnet) that the system has ever blocked stays blocked — even if
+  it stops appearing in recent logs (for example after it leaves the NPM
+  ~30-day log-retention window, or once WHOIS subnet consolidation groups it
+  into a larger range).
+- The **source of truth** for "all blocked IPs" is the **SQLite blocklist
+  ledger** (`app.db` → `blocklist_entries` / `blocklist_events`), not git
+  history. Each scan syncs the desired blocklist into the ledger; the router's
+  cumulative state is derived from it. `app/utils/blocklist_history.py` is a
+  read-only fallback only.
+- The sync only ever **adds** entries. The only automatic removals are router
+  entries that were never blocked by the system — i.e. absent from the ledger
+  (manual / rogue entries).
+- To explicitly unblock an IP, remove it manually via the web UI
+  (`/blocklist` → remove) or directly on the router; the automated sync will
+  not re-add entries that are not part of a scan.
+
+> **Deployment note:** runtime data (blocklists, reports, the DB) is **never
+> committed to git**. Keeping it untracked is what makes `git pull` updates
+> conflict-free — see [`DEPLOYMENT.md`](.github/instructions/DEPLOYMENT.md)
+> and the `deploy/` scripts.
+
+Each consolidated scan with `--update-firewall` also writes a timestamped
+change report to `reports/app/YYYY-MM-DD-hh-mm-ss.json`: the number and list
+of entries added / removed (complete-set delta), the full cumulative blocked
+list, and the router sync changes. It also persists a firewall snapshot into
+the `firewall_snapshots` SQLite tables for long-term audit (F001).
+
+### Report retention
+
+Generated files under `reports/` are pruned automatically after each
+consolidated scan: every subdirectory keeps at most
+`REPORT_RETENTION_MAX_FILES` files (default 10), all newer than
+`REPORT_RETENTION_DAYS` days (default 30). The blocklist files
+(`reports/app/data/blocklist_ipv4.txt` / `blocklist_ipv6.txt`) are always
+protected and never pruned. Tune via `REPORT_RETENTION_DAYS` /
+`REPORT_RETENTION_MAX_FILES`; `--dry-run` previews the cleanup without
+deleting.

+
+## Artifacts
+
+| Area | Producer and formats | Current role and consumers | Classification |
+| --- | --- | --- | --- |
+| `copyparty/` | `Analyzer.write_report()` creates timestamped `.txt`; `write_data()` creates per-IP CSV/JSON, denied-path CSV, flagged/banned IP TXT, `requests.csv`, `authed_users.json`, and `mikrotik-block.rsc`. | Reports API serves top-level text reports. `requests.csv` is imported by `app.db.backfill`; per-run data supports inspection and legacy workflows. Retention prunes generated files. | Request rows and per-scan IP stats are canonical in `requests` and `ip_stats`; rendered summaries and exports are derived. |
+| `npm/` | Same analyzer outputs, plus user-agent and host summary CSV files. | Same consumers as copyparty. `requests.csv` is a legacy backfill input; retention prunes generated files. | Request rows and per-scan IP stats are canonical in `requests` and `ip_stats`; summaries and exports are derived. |
+| `app/data/` | Consolidated scan writes `blocklist_ipv4.txt` and `blocklist_ipv6.txt`. | Blocklist UI/API reads these files; scan history reconstruction and firewall sync use them as current/compatibility inputs. Retention explicitly protects them. | Operational compatibility exports. Canonical blocked targets and events belong in `blocklist_entries` and `blocklist_events`; keep files until every consumer uses the DB and git-history contract is replaced. |
+| `app/` timestamped JSON | `write_blocklist_report()` emits scan/firewall change reports when the router is reachable. | Human-readable audit trail containing run delta, cumulative targets, router changes, dry-run state, and errors; retained under report retention. | Derived audit artifact. Preserve structured fields and source scan association in the DB before considering file retirement. |
+| `mikrotik/` | `MikrotikFirewall.save_state_report()` writes timestamped JSON snapshots and report data; latest state is also written to `data/mikrotik/*.json`. | Firewall UI/API displays current state and snapshot history. `app.db.backfill` currently imports only the latest `data/mikrotik` snapshot; runtime snapshot persistence uses `firewall_snapshots`, `firewall_address_list_entries`, and `firewall_rule_entries`. | Firewall rows and snapshots are canonical in the DB once persisted. Keep JSON exports during migration and retain any git-diff inputs required by deployment/audit. |
+
+## Consumers
+
+- `GET /api/reports/<source>` lists top-level files in the selected report
+  directory; `GET /api/reports/<source>/<path>` reads a file below it.
+- The reports page consumes those endpoints. Scan status and dashboard helpers
+  select the newest source and MikroTik report files for display.
+- `/api/blocklist` reads the consolidated IPv4/IPv6 text files. Scan history
+  reconstruction and firewall sync also consume those files alongside the
+  SQLite ledger and git history.
+- RouterOS `.rsc` exports and firewall synchronization consume generated
+  targets; these are operational outputs, not disposable presentation files.
+- `app.db.backfill` imports per-source `requests.csv`, blocklist history, and
+  the latest common MikroTik JSON snapshot. It does not currently import all
+  timestamped reports or all historical MikroTik snapshots.
+- Report retention removes old generated artifacts after consolidated scans,
+  subject to configured age/file-count limits; the consolidated blocklist
+  files are protected.
+
+## Restructuring Implications
+
+- Keep `requests`, `ip_stats`, blocklist tables, and firewall snapshot tables
+  as the queryable source of truth for facts they already represent. Avoid
+  copying those facts into a generic report blob.
+- A future report-artifact record should store metadata and structured fields
+  that have no canonical home yet. Rendered text/CSV/JSON should be generated
+  from those records or remain an explicit export.
+- Preserve source paths, generated timestamps, scan IDs, and hashes during
+  import so DB records can be traced back to original files.
+- Do not retire blocklist exports, RouterOS scripts, or source logs until
+  their consumers and audit requirements have explicit replacements.
+
+## Database and API Design
+
+### Canonical Data
+
+Continue treating normalized domain tables as canonical for facts they
+already represent:
+
+- `requests` for parsed request events.
+- `ip_stats` for per-IP/per-scan aggregates.
+- `scans` and `scans_sources` for run status, parameters, and source counts.
+- `blocklist_entries`, `blocklist_reasons`, and `blocklist_events` for block
+  decisions and history.
+- `firewall_snapshots`, `firewall_address_list_entries`, and
+  `firewall_rule_entries` for router state.
+
+Add a `report_artifacts` table only for report-specific summaries that cannot
+be reconstructed from those canonical rows. Proposed columns:
+
+| Column | Purpose |
+| --- | --- |
+| `id` | Integer primary key. |
+| `source` | `copyparty`, `npm`, `app`, or `mikrotik`. Keep as text because `log_sources` currently covers only request sources. |
+| `scan_id` | Nullable link to the generating scan; legacy imports may not have a known scan. |
+| `report_type` | Stable type such as `analyzer_summary`, `blocklist_change`, or `firewall_snapshot_summary`. |
+| `generated_at` | Original generation timestamp when known; otherwise import time plus an explicit unknown/original-time flag in metadata. |
+| `schema_version` | Version of the structured payload shape. |
+| `payload_json` | Structured report-specific summary, not a duplicate of requests or raw logs. |
+| `original_path` | Relative source path for provenance and legacy lookup. |
+| `content_sha256` | Hash of imported source content for integrity and idempotent import. |
+| `created_at` | Database import/creation timestamp. |
+
+Use a unique index on `(original_path, content_sha256)` for idempotent file
+imports. Keep payload schemas type-specific and versioned. Do not copy
+`requests.csv`, `ips.json`, firewall rows, or blocklists wholesale into
+`payload_json`; query their canonical tables and generate exports from those
+tables. If a rendered text report is retained as a database artifact, store
+its report-specific structured inputs and render text on demand rather than
+using opaque text as the only source of truth.
+
+### API Transition Contract
+
+- Add `GET /api/reports` with optional `source`, `type`, `since`, `until`,
+  `limit`, and opaque `cursor` filters. Return a stable list of artifact
+  metadata: `id`, `source`, `scan_id`, `type`, `generated_at`, and available
+  export formats. Enforce a bounded default and maximum page size.
+- Add `GET /api/report-artifacts/<artifact_id>` for the structured payload and
+  provenance metadata. Use a distinct path because `/api/reports/<source>`
+  already owns the one-segment route shape.
+- Add `GET /api/report-artifacts/<artifact_id>/export` for supported report types and formats
+  (initially JSON and, where useful, CSV/TXT). Generate exports from canonical
+  tables and versioned artifact payloads; do not accept filesystem paths from
+  a database-backed export request.
+- Preserve the current source/path routes as a read-only compatibility
+  fallback while files remain. The reports page should consume DB metadata
+  first, then offer legacy files when no imported artifact exists. Return
+  stable JSON errors for unknown IDs, unsupported formats, and unavailable
+  DB state.
+- Keep ordering deterministic (`generated_at DESC`, then `id DESC`), validate
+  filter values, and use cursor pagination for large histories. Do not expose
+  absolute server paths in list responses.
+
+### Sensitive and Large Content
+
+Do not include raw request lines or full request histories in report payloads;
+those belong in the dedicated log-storage design and require separate access
+and retention controls. Keep high-volume CSV exports generated on demand. Treat
+IP addresses, paths/query strings, user names, user agents, and firewall state
+as sensitive operational data: the existing web server must remain
+localhost-only, payloads should include only fields needed by the report, and
+new endpoints must not expose raw log data by default. Backups and exported
+files inherit the same access and retention requirements as the database.
+
+## Migration Implementation Status
+
+- Schema v2 adds `report_artifacts` with source, scan link, report type,
+  generation time, payload version, original relative path, and SHA-256 hash.
+- `python -m app.db.backfill --dry-run --reports-only` inventories supported
+  report files by source and format. The importer is idempotent, preserves
+  malformed JSON as text with a parse error, reports unreadable/oversized
+  files, and never modifies source files. It skips exports owned by canonical
+  tables (for example `requests.csv` and current blocklists).
+- New analyzer text summaries and consolidated blocklist change reports are
+  written to SQLite and their existing files. Firewall snapshots continue to
+  be persisted in the normalized firewall tables.
+- The Reports page lists database artifacts first, supports cursor pagination
+  and JSON/CSV/TXT downloads, and retains the existing file-backed routes as a
+  fallback for unmigrated files.
+- Validation covers idempotency, malformed/oversized inputs, source/format
+  counts, backup/restore, dual-write payloads, and API fallback. A workspace
+  dry-run found 76 files: 60 eligible, 16 canonical exports skipped, and none
+  unmappable at the time of the check.
+- No report files have been retired. Keep this gate closed until every listed
+  consumer has moved or has an explicit compatibility requirement, and a
+  production backup/restore and parity review has been approved.
