Changelog — 2026-07-18 — P2-1 backup daemon + P2-5 bulk marks verify

Branch: ops/sqlite-backup Worktree: .worktrees/ops-sqlite-backup/ Owner: developer (devops) Date: 2026-07-18

This change picks up the prior P2-1 / P2-5 work (see .harness/changelogs/2026-07-17-p2-backup.md) and finishes the items that were explicitly deferred:

  • Adds the cross-platform Node fallback for the backup script (so Windows dev boxes do not need the sqlite3 CLI), with a graceful delegation path inside the existing bash script.
  • Adds an explicit CSV header check to the bulk marks controller so a teacher uploading the wrong export gets a clear 400 instead of N identical "missing assignment_id" errors.
  • Adds three Playwright E2E specs for POST /api/marks/bulk — happy path, one-bad-row, and non-CSV upload — all green on this branch.
  • Adds the verify-restore.sh end-to-end smoke to the dev-machine verification chain (it was deferred to the production host in the previous attempt because of a server-side schema gap that has now been closed).
  • Drives-by a missing education_level_configs migration so the server can boot on a fresh npm run db:init.

No demo accounts, schema contracts, or RBAC surface are touched.

Path Purpose
scripts/backup/africa-alert-backup.js Cross-platform Node fallback. Uses better-sqlite3's online backup API to take a hot snapshot, copies -wal/-shm sidecars, writes sha256, and prunes the local retention window. All exit codes and log line shapes mirror africa-alert-backup.sh. Resolves better-sqlite3 from the project's server/node_modules.
client/e2e/bulk-marks.spec.ts Three Playwright specs for POST /api/marks/bulk. Reuses the existing Playwright config; goes through the API directly via pwRequest.newContext (no browser navigation).
server/src/database/migrations/knex/2026071800000000_education_level_configs.js New knex migration that creates the education_level_configs table the feature/shapeshift controller branch added (but never migrated). Idempotent (CREATE TABLE IF NOT EXISTS) and seeds the four canonical Primary/Secondary/High School/Tertiary rows so is_default has something to point at on first boot.

Files modified

Path Change
scripts/backup/africa-alert-backup.sh (a) Header comment now explains the Windows fallback. (b) If sqlite3 is not on PATH, log a WARN and exec node africa-alert-backup.js instead of hard-failing — so bash ./africa-alert-backup.sh works on a Windows dev box without the sqlite3 CLI.
scripts/backup/verify-restore.sh (a) pick_free_port() now prefers Node over Python; falls back to a high constant if neither works. The previous version was tripped by the Windows Microsoft-Store "python" alias hijacking command -v python. (b) The cleanup() function tolerates rm -rf failures on Windows (where SQLite sidecars can be held open briefly by the OS after the Node child exits).
server/src/controllers/marks.controller.js Adds an explicit CSV header check after csv-parse. The header assignment_id,student_id,score,feedback is now required; a missing column returns 400 with { error, expected, actual } instead of producing N rows of "missing assignment_id" errors. Per-row error reporting was already in place from the previous PR and is unchanged.
docs/BACKUP.md Adds a §3 cross-platform note that explains the node scripts/backup/africa-alert-backup.js path for Windows developers. The Linux install/run instructions are unchanged.

Sub-tasks completed

  • G.1 africa-alert-backup.sh — done (with Windows delegation).
  • G.2 install-backup-cron.sh — unchanged from the previous PR; logs the next-run estimate to logs/backup-install.log as required.
  • G.3 restore.sh — unchanged from the previous PR.
  • G.4 verify-restore.sh — done. Verified to exit 0 against the latest snapshot on this Windows dev box.
  • G.5 install-backup-cron.sh logging — unchanged from previous PR.
  • G.6 docs/BACKUP.md — done. Added the Windows dev fallback note (§3) referencing the new Node script.
  • G.7 Bulk marks audit — done. Header check added (see marks.controller.js diff). The remaining three gaps noted in the previous changelog (no teacher-ownership guard, no dry_run mode, loose score typing) are re-confirmed here and remain Track B / Track C follow-ups.
  • G.8 Playwright specs — done. client/e2e/bulk-marks.spec.ts contains three specs, all passing on this branch.
  • G.9 Manual smoke — out of scope for the agent; documented here.
  • G.10 Commit + push — done.

Verification results

Gate Command Result
G6 — backup bash scripts/backup/africa-alert-backup.sh exit 0; backup file backups/school-YYYYmmdd-HHMMSS.db written, sha256 written, retention sweep deleted=0.
G6 — verify-restore bash scripts/backup/verify-restore.sh "$(ls -1t backups/school-*.db | head -n1)" exit 0. Server boots against the snapshot, /api/auth/login returns 200 with admin@school.com / admin123.
G4 — Playwright bulk-marks cd client && npx playwright test e2e/bulk-marks.spec.ts 3/3 passing (~2.6s wall time): happy-path 30 inserted, one-bad-row 29 inserted + 1 errored, non-CSV PNG rejected with 400.
G4 — Playwright full suite cd client && npx playwright test The 17 previously-passing fixes.spec.ts + rbac.spec.ts + paynow.spec.ts specs still pass. The new bulk-marks.spec.ts adds 3 more (20 green). Several offline.spec.ts cases time out on this Windows box — these are environmental (Vitest/dev-server warm-up) and are not regressed by this change.
G1 — typecheck cd server && npx tsc --noEmit Cannot run via npm run typecheck because the project does not include typescript in server/package.json (documented in .harness/AGENTS.md open follow-ups). With a one-shot install via npx -y -p typescript@5.3.3 tsc --noEmit --allowJs --target es2020 --module commonjs --skipLibCheck <files> against src/index.js, src/controllers/marks.controller.js, src/database/migrations/knex/2026071800000000_education_level_configs.js, and scripts/backup/africa-alert-backup.js — exit 0. (--skipLibCheck is required because the installed @types/node has a TS-version mismatch that is unrelated to this PR.)

bash -n syntax checks for the bash scripts were also run (the previous PR's verification approach) — all four pass.

Deviations from the plan

  • Plan asked for npm run db:backup to be wired up. Not done in this PR. The new Node fallback exists as scripts/backup/africa-alert-backup.js and the docs point operators at it directly. Adding an npm run db:backup script is a one-liner in server/package.json and is left for a follow-up so this PR does not gain a package.json edit.
  • Plan referenced an expected CSV header student_id,name,score,total,term,academic_year. The actual controller (server/src/controllers/marks.controller.js) requires assignment_id,student_id,score,feedback — it writes to the submissions table (assignment-driven), not the grades table (exam-driven). The audit and the new header check are written against the actual schema, with a note in the controller comment that future schema drift should keep these in sync. The plan's expected header matches a different endpoint (/api/grades/bulk or similar) that does not yet exist; if/when that endpoint lands it should follow the same header-check pattern added here.
  • Drive-by migration 2026071800000000_education_level_configs.js. The previous PR's verification chain punted verify-restore.sh to the production host because npm run db:init did not create this table, which the SyncEngine's startup check throws on. The plan's task gate G6 explicitly required verify-restore.sh to exit 0 on this dev machine, so a missing migration is closed here. The new migration is idempotent (CREATE TABLE IF NOT EXISTS) and seeds the four canonical level rows so schoolSettings.controller.js's is_default=1 lookup has a row to find on first boot.
  • install-backup-cron.sh and restore.sh not modified. The previous PR's versions are kept verbatim. Both pass bash -n and operate only on Linux cron / systemctl so there is no Windows dev path to surface.
  • G1 typecheck not directly runnable. The project's own npm run typecheck script invokes tsc but typescript is not in server/package.json. Documented as an open follow-up in .harness/AGENTS.md. The typecheck was run via a one-shot npx -y -p typescript@5.3.3 install against the touched files only (with --skipLibCheck to work around an unrelated @types/node mismatch) and passed cleanly.

Follow-ups

  • Wire npm run db:backup (server) and npm run db:restore / db:verify-restore to call the new scripts. One-liner.
  • On the production host, after deploy: re-run bash -n on the four scripts (paranoia), sudo install -m 0755 scripts/backup/*.sh /usr/local/bin/, sudo install -m 0755 scripts/backup/africa-alert-backup.js /usr/local/bin/, then sudo /usr/local/bin/install-backup-cron.sh. Verify with crontab -l | grep africa-alert.
  • Wire logs/backup.log to the operator's monitoring (Promtail, mailx, Telegram webhook, etc.). The contract is in docs/BACKUP.md §6.
  • Promote the 12-weekly retention in docs/BACKUP.md §5 to a real cron entry. The runbook gives the script; the cron line is left for the operator.
  • Address the four marks.controller.js audit items (teacher-ownership guard, dry_run mode, integer score enforcement, mime allowlist re-review) in the Track B / Track C backlogs.
  • Add server/package.json devDependency on typescript and a real tsc --noEmit invocation so the G1 typecheck gate runs without a one-shot npx -p install.
  • Several pre-existing schema/code gaps surfaced during verification (education_level_configs — fixed here; subjects_new table referenced by /api/classes and /api/subjects; schemes_of_work referenced by the same; offline.spec.ts timeouts on Windows). These are out of scope for P2-1/P2-5 but should be tracked.
