A learner submits a capstone, our +own AI says how complete it is and what is left, a mentor confirms, and a passed track earns a +certificate the learner can add to LinkedIn. + +## What the learner sees + +1. On the capstone chapter, a **Capstone check** block asks for a GitHub repo URL (and a live URL + for Level 2). +2. They press **Check my capstone**. Within about a minute they see: + - **Complete** or **Not complete yet**, and a percentage. + - **What is left**: one card per unmet criterion, each with numbered steps. + - **Quality notes**: what is good and what would make it better. + - A line saying a mentor will confirm the result. +3. They fix things and press **Check again**. Every attempt is kept as history. + +## What the mentor sees + +A check reaches the existing review queue when the AI says it is complete, or when the learner +presses **Ask my mentor to look**. There is one waiting item per learner per capstone: a newer +check replaces the one already waiting. The review page shows the full report: automated check +results, per-criterion scores with the evidence the model cited, the commit, the model, tokens +and cost, plus every earlier check. The review form is prefilled from the AI result, so +**Approve** confirms it, and changing the feedback, score or verdict overrides it. This writes +the ordinary `Review` row, so the queue, notifications and needs-revision loop work as today. **The AI never passes a learner on +its own.** Only a mentor-confirmed pass counts toward a certificate. + +## How a check runs + +``` +submit -> automated checks -> (stop early if a hard gate fails) -> Sonnet grade -> report +``` + +**Automated checks** (no model, no cost), defined per pack: + +| Check | How | +| --- | --- | +| Repo reachable | GitHub API: repo exists and is public, default branch, head commit SHA | +| Builds and tests pass | Status of the latest GitHub Actions run on that commit.

The check takes about a minute. +pack: capstone/rubric.yaml +``` +```` + +Check ids default to the check name (`live_ok`), so a criterion gates on `[live_ok]`. Give an +id when a pack has two checks of the same kind. `passLevel` (default: full marks) sets the level +that counts as met. A snapshot example can include `live.html` so calibration never touches the +network. + +## Calibration test + +- **CI (free):** loader and schema tests for every pack, plus grading-pipeline tests with a + recorded model response, so gates, recomputed percent and caps are covered without the API. +- A course with several packs (`capstone/capstone-1.yaml`, `capstone-2.yaml`) keeps each pack's + examples in `calibration//`; a lone `capstone/rubric.yaml` uses `calibration/`. +- **Live (paid, run by hand):** `pnpm --dir server capstone:calibrate --pack ` runs every + calibration example through the real checker and fails if `completed` differs or `percent` + falls outside `tolerance`. It prints the cost before and after. Run it when a pack changes. + +## Certificates + +**When:** a learner's enrollment is complete and every capstone check in the course has a +mentor-confirmed pass. Issued once per enrollment; a mentor or admin can revoke. + +**What it says:** the learner's name, the track title (for example "Level 2: Personal Site and +Outreach Engine"), "Dev Weekends", the issue date, the skills covered, a unique id such as +`DW-L2-7K3F9QXM`, and the course's trainer as issuer: the instructor name the catalog shows for +the course (Zeeshan Adil for the Dev Weekends tracks). `certificate.issuer.name` in course.yaml +overrides it, for example Aqib Nawab on the multi-vendor marketplace course. + +**Configured per course** in `course.yaml`: + +```yaml +certificate: + program: Dev Weekends Mentorship + title: "Level 2: Personal Site and Outreach Engine" + code: L2 + skills: [Personal site, Outreach engine, Link tracking, Web analytics] +``` + +**Public verify page** at `/verify/`: no sign-in, shows the certificate, its status (valid +or revoked), skills, and the capstone repo link. It sets Open Graph tags so a shared link shows +the certificate image. + +**Add to LinkedIn:** one button that opens LinkedIn's add-to-profile form pre-filled: + +``` +https://www.linkedin.com/profile/add?startTask=CERTIFICATION_NAME + &name=&organizationName=Edorax&issueYear=2026&issueMonth=11 + &certUrl=<verify url>&certId=<id> +``` + +Plus **Share on LinkedIn** (post with the verify link) and **Download image** (1200 x 627 PNG +rendered on the server with `next/og`). + +**Look:** Edorax type (Unbounded headings, DM Sans body), white card with a 1px line border and +square corners, ink text on paper, no gradients, no ribbons, no seals, no script fonts. The Dev +Weekends wordmark with its seven week bars carries the issuer mark in black and white. One +cobalt element at most (the verify link). It should read like a well set document, not a +template. + +## Level 3 oral exam (later phase) + +Each check is a list of stages: `automated`, `ai_grade`, and later `oral_exam`. A pack with +`oralExam.enabled: true` will require a passed oral stage, built on the existing AI interview +block, before the mentor can confirm. Phase 1 ships the stage interface and the pack field only. + +## Security + +- Fetching learner URLs is new for Edorax (the review queue doc says we do not). Rules: HTTPS + only, DNS resolved and private, loopback, link-local and metadata ranges refused (also after + redirects), GET only, no cookies, 5 s timeout, 512 KB cap. +- GitHub is read through its API (repo, commit, tags, CI) and its raw file host (file contents), with no token by default. +- Repo text is untrusted. The prompt treats it as data, output is schema-bound, the server + recomputes the score, gates are enforced in code, and a mentor confirms every pass. +- Rubric packs stay server-only, like every block config. + +## Data model + +- `BlockType.CAPSTONE_CHECK`. +- `CapstoneCheck`: one row per attempt, linked to the `Response` it creates. Holds repo URL, + live URL, commit SHA, pack id and version, status (`QUEUED`, `RUNNING`, `DONE`, `FAILED`), + automated results, AI report, percent, completed, model, tokens, cost. Mentor decisions use the + existing `Review`. +- `Certificate`: public id, user, course, enrollment (unique), recipient name and title snapshot, + skills, issued at, revoked at and reason. + +## Needs keys or approval + +| Item | Who | +| --- | --- | +| Nothing for the AI key: the checker uses the `ANTHROPIC_API_KEY` already set for chapter Q&A | None | +| `GITHUB_TOKEN` is optional. Files come from GitHub's raw host, so a check uses about five API calls and the 60 an hour limit without a token covers about 12 checks an hour. A read-only token raises that to 5,000 calls if needed | Optional | +| LinkedIn lists Edorax, never Dev Weekends, as the issuer. When the platform has its own LinkedIn page, set its id as `CERTIFICATE_LINKEDIN_ORG_ID`; until then LinkedIn gets "Edorax" as plain text | Later | +| Optional title under the trainer's name: `certificate.issuer.title` in course.yaml | Optional | +| Daily caps above (env, defaults in the cost table) | User | +| One live calibration run per level pack (`pnpm capstone:calibrate --pack <rubric.yaml> --live --record`, about $0.20 per example) | Level sessions, with the API key | +| Each level's capstone template ships a CI workflow that builds and runs tests | Level sessions | + +## Known limits and follow-ups + +- The desktop app's reader does not draw the capstone block yet; it needs the same block in + `packages/learning-ui` (the web app has it). Learners can use the web app meanwhile. +- Certificate eligibility counts every capstone block in the course. It does not yet filter by the + learner's course variant or release. +- Claude's server-side refusal fallback is not enabled. A refused grade fails the check with a + message telling the learner to send it to their mentor. +- Checks run inside the API process. A restart marks running checks as interrupted after five + minutes so the learner can check again. A job queue can replace this if volume grows. +- Level 3's oral exam stage is the next phase (see above). +- Asked for by Level 2, not built yet: the checker's own screenshots of the live URL at 375 and + 1280 px for the grader.
