Take a look at ../cs124.org and how it does ncu:update. It gathers all projec...

I have a complete picture. Now let me write the plan.

Now let me verify the script type-checks and runs. I'll do a dry-run to make sure it works before applying anything.

The rewrite works. Running verbose dry-run:

• Scans all 29 packages in a single ncu call (previously 29 separate calls, doubled to ~58 in verbose mode)
• Correctly aggregates: @types/node shows as shared across 17 packages
• No available updates — 19 pending cooldown
• @repo/ prefix stripping works (names like web, api, mail)

Let me also confirm it type-checks.

Done. The script works: plain bun run ncu reports "All dependencies are up to date", bun run ncu --verbose correctly groups the 19 cooldown-blocked updates across 29 packages (e.g., @types/node listed once with all 17 affected packages shown inline).

scripts/check-updates.ts now uses the gather-merge-run-distribute pattern:

• Before: 29 ncu invocations per run, 58 in verbose mode
• After: 2 ncu invocations (merged deps + root packageManager), 3 in verbose mode (+ cooldown pass)

Key behavior changes beyond the speedup:

1. Peer dependencies are no longer touched. packages/auth/package.json's next: >=14 and drizzle-orm: >=0.30 would previously have been re-pinned by ncu -u. Now only dependencies and devDependencies are merged/distributed, so compatibility ranges stay as ranges.
2. packageManager field is now handled. Root bun@1.3.11 will get updated when a newer bun ships (previously not checked).
3. Output format unchanged — same headers, colors, padding, [pkg1, pkg2, ...] grouping, and trailing hints.

.ncurc.js and the package.json ncu/ncu:update entries are untouched — the invocation surface is identical.

No — Playwright's --project doesn't parse commas. You repeat the flag:

bunx playwright test --project=syllabus --project=navigation

Or use --project with a glob/regex via shell expansion, but the canonical way is just to repeat the flag.

Found it — testing/e2e/run-projects.ts:398-411 is where project args are parsed. The --project= handling matches the whole string to ALL_PROJECTS, so --project=syllabus,navigation falls through to extraArgs.

Script still parses fine. Now --project=syllabus,navigation (and also the bare positional form syllabus,navigation) will be split, validated against ALL_PROJECTS, and pushed as separate project names. If any name in the list is invalid, the whole arg falls through to extraArgs so Playwright's own error surfaces.

Both forms work:

• bun run test:e2e --project=syllabus,navigation
• bun run test:e2e syllabus,navigation
• bun run test:e2e syllabus navigation (unchanged — space-separated still works)

Four modified files, no untracked files, no debugging statements spotted. I see three logically distinct changes:

1. scripts/check-updates.ts — the gather-merge-distribute ncu rewrite we just did
2. testing/e2e/run-projects.ts — the comma-separated --project support we just added
3. apps/api/package.json + bun.lock — a hono bump from 4.12.9 → 4.12.12 (this was already modified when our session started, unrelated to either of the above)

Three commits on ncu_update:

• f19f7fa Speed up ncu by merging deps and running it once
• 4c44228 Accept comma-separated project names in e2e runner
• a5fe657 Update hono to 4.12.12

Working tree clean.

Cause confirmed. Now let me check if anything else consumes getMeetingRoomSize before fixing.

Diagnosis

The failures are caused by commit 54e1c0b ("Use websocket connections for dashboard student count instead of high-water mark"), not by anything in this branch. That commit changed totalCount from a high-water mark of completions to a live count of sockets in the meeting room — but the implementation counts all sockets, not just students.

Root cause: apps/api/src/socket.ts:155-160

export async function getMeetingRoomSize(meetingSlug, semester): Promise<number> {
  if (!io) return 0;
  const room = getMeetingRoom(meetingSlug, semester);
  const sockets = await io.in(room).fetchSockets();
  return sockets.length;   // ← counts everyone, including instructors
}

The commit's intent (per message + test) was "connected students", but the socket handshake isn't authenticated and the count includes instructor sockets. When a test instructor opens /testing/components/activity-stages, their own socket joins the room via useSocket in activity-stage-context.tsx:133, so connectedStudents returns 1 before any student shows up.

That makes stage.totalCount === 1, and activity-stage-instructor.tsx:847-849 renders "0 of 1" instead of "0 completed" (the falsy branch only fires when totalCount === 0).

Failing assertions (only the first hit because maxFailures: 1):

1. activity-stages.spec.ts:118-120 — "instructor can start a session" expects "0 completed"
2. activity-stages.spec.ts:340-343 — "instructor sees completion count update" (first check)
3. activity-stages.spec.ts:360-363 — same test, expects "1 of 1" → would get "1 of 2" (instructor + student)
4. activity-stages.spec.ts:398-401 — "total count reflects connected students" expects "of 3" → would get "of 4" (the test author's own assumption was already wrong)
5. activity-stages.spec.ts:412-415 — same test, "1 of 3" → "1 of 4"
6. full-activity-flow.spec.ts:107-109 — instructor-only session expects "0 completed"

The test at (4)/(5) was added in that same commit but evidently was never actually run successfully — with today's implementation it can't pass.

Grouped stages are fine. The full-activity-flow.spec.ts "1 of 1 group" assertions go through the totalGroupsMap branch at activity-stages.ts:354, which is unaffected.

Proposed fix

Authenticate the socket.io handshake and filter the room count to students only. The pieces already exist in the auth middleware:

1. apps/api/src/socket.ts — add a socket.io handshake middleware that parses the cookie header via the existing getSessionToken + verifySession helpers from middleware/auth.ts and stores role on socket.data. Add a SocketData generic parameter to SocketServer<...> so the type is preserved.
2. getMeetingRoomSize — filter fetchSockets() to s.data.role === "student".

No client changes needed — the browser already sends the cookie on the ws handshake (withCredentials: true on the client, credentials: true on the server CORS).

Side effect (desirable): the dashboard's "X of Y" now correctly reflects students only, matching the commit's original intent.

Want me to implement this? It touches auth on the websocket layer, so I wanted to flag it before making the change.

Now let me re-read the file to verify everything stitches together cleanly.

Let me type-check the API package to confirm the changes compile cleanly.

Clean compile. Now let me verify one concern: I want to make sure socket.data is writable at handshake time (socket.io initializes it as {} and lets you assign properties) — the successful typecheck confirms this, and the handshake middleware pattern is idiomatic socket.io.

Let me also quickly sanity-check that the test E2E users actually have proper roles flowing through verifySession:

Fix is in. Summary of the change to apps/api/src/socket.ts:

1. SocketData interface — new typed role field on each socket
2. Handshake middleware (io.use) — parses the session cookie via the existing getSessionToken + verifySession helpers and stores user.role on socket.data.role. Auth failures don't block the connection — anonymous clients just land as role: null.
3. getMeetingRoomSize — now filters to s.data.role === "student", excluding instructors, staff, and anonymous visitors. Docstring updated to reflect the actual semantics.
4. Generics — extended SocketServer / Socket with a 4th type argument so socket.data.role is properly typed (3rd generic is Record<string, never> since we have no inter-server events).

Zero client-side changes — the browser already sends cookies on the socket.io handshake (withCredentials: true on the client, credentials: true in the server CORS).

bun run tsc in apps/api passes clean.

The 6 broken assertions should all pass now:

• "0 completed" cases: instructor-only session → 0 students in room → totalCount=0 → hits the "0 completed" branch at activity-stage-instructor.tsx:849
• "1 of 1" case: instructor + 1 student → only student counts → totalCount=1
• "of 3" / "1 of 3" cases: instructor + 3 students → totalCount=3
• full-activity-flow.spec.ts:108 same as (1)

You can re-run activity-stages and full-activity-flow whenever ready. Note the dev server has to restart to pick up the socket.ts change (the API process needs a fresh import).

Found it — submissions/.

Now I have what I need. Let me draft the plain-text abstract modeled on the existing ITEL submission, compressed to 300–500 words for the CS Summer Teaching audience. I'll put it in a new submissions/illinois-summer-teaching-2026/ directory and word-count after.

454 words — comfortably inside the 300–500 range. Saved to submissions/illinois-summer-teaching-2026/submission.txt.

Structure (modeled on the ITEL submission, compressed for a 10-min CS-teaching talk):

• Header: title, author, track (Pathways for AI in CS Education and Teaching — the obvious fit)
• Framing paragraph: what the course is + the pitch that the techniques generalize beyond its specific topic
• Three sections, each matching ~2–3 minutes of talk time: Conversational assessment, Agent-guided discussion, Conversational programming
• Closing: demo plan + live pointer to production infrastructure

Editorial choices vs. the ITEL version:

• Dropped the Interactive Pedagogical Tools section (digit network / neuron explorer / embedding explorer) — those are topic-specific to AI and don't generalize for a CS teaching audience
• Dropped citations/figures since this is plain text for a Google Form
• Led with "three techniques that generalize" since the CS audience wants transferable patterns, not just a course report
• No em dashes (per your writing preference), no markdown formatting
• Kept "including the dead ends and course corrections" as the hook for the conversational programming section — CS educators will relate

Heads up: the CFP deadline is April 15, 2026 (5 days from today), and submission is via the Google Form linked from the CFP page — not a file upload, so you'll paste the body text in.

Want me to tighten it further, add or swap a section, or try a different title/framing?

Good restructure. Let me rewrite it around that three-part title.

426 words, inside the 300–500 range.

Three sections mapped to the three-part title:

• A course about AI — who it's for, meeting structure (inductive explorations / labs / discussions), Gen Ed transition
• Built by AI — conversational programming with Claude Code, 167 sessions, 50K LOC, the public archive
• Powered by AI — conversational assessment as the centerpiece with the full two-agent explanation, plus a one-sentence tag that the same pattern extends to group discussions and reading prep

Closing sentence mentions both demo types (conversational assessment + a live Claude Code session) so the talk plan is clear to reviewers.

Want me to trade the two-sentence mention of group discussions / reading prep for a beat on the interactive pedagogical tools (digit network, neuron explorer, embedding explorer) instead? You've got ~75 words of headroom before the 500 cap if you want both.

Done. Title is now "A Course About AI Built With AI Powered By AI" and the middle section header matches.

416 words. Section markers dropped; the three paragraphs now mirror the title's arc implicitly (what the course is → how the platform was built → how AI runs in the classroom) without naming it.

431 words. The new closing sentence of the first paragraph:

Because it treats AI as both a technical system and a social force, the course is being designed to satisfy general education requirements in both quantitative and humanities categories, an unusual combination that reflects its dual emphasis.

Leads with the pedagogical rationale (technical + social), closes with the institutional consequence (fills gen-ed on both sides), and avoids the Illinois-specific CS 108 / Quantitative Reasoning / Philosophical Perspectives jargon.

Checked. Out of 793 distinct Gen Ed courses in the spreadsheet (72 in QR I/II and 313 in Humanities), exactly one course currently satisfies both a Quantitative Reasoning category and a Humanities category:

PHIL 103: Logic and Reasoning — QR II + Humanities (Hist & Phil)

And that one is a slam-dunk natural fit because formal logic is literally a quantitative branch of philosophy. A course about AI landing in both categories would be meaningfully different — it's not a logic course, it's a substantively technical + substantively humanistic treatment of a single subject.

So "unusual" is actually understating it. Two directions you could take:

1. Keep "unusual" — safer, no need to back up the claim if someone pushes.
2. Strengthen it — e.g., "only one current Illinois course satisfies both Gen Ed categories, and this one would be the second."

I'd lean toward a softer strengthening rather than a claim that invites fact-checking: something like "rare" or "nearly unique." Want me to swap?

Yeah — formal logic is the one place the quant/humanities boundary was always going to be permeable. Want me to make any edit to the sentence, or leave it?

Keeping "unusual" as-is. No changes.

Done.

Swapped "sessions" → "conversations" in both places. This also ties more naturally to the "conversational programming" framing (and let me drop "conversational" from "conversational turns" since it becomes redundant).

467 words, still within the 300–500 range.

What changed:

• Dropped the final paragraph about the talk contents.
• Para 2 (built): pulled "real-time activity framework" out of the enumeration and replaced it with a new standalone sentence after "Nobody wrote or read the source code directly.":

  The platform also includes a novel real-time meeting coordination framework that synchronizes students through multi-stage in-class activities, with live instructor controls and a projector view for classroom use.

• Para 3 (powered): reframed the opening to introduce two modes, and added the interactive demonstrations as the first mode:

  In class, students encounter AI in two ways: as a topic they investigate hands-on, and as a participant in their learning. Exploratory meetings feature interactive demonstrations built for the course, including a digit recognition neural network students can draw into and train live, a single-neuron explorer for adjusting weights and activation functions, and an embedding explorer for computing word analogies and visualizing semantic similarity. The centerpiece of the second mode is conversational assessment: ...

Conversational assessment stays as the centerpiece of the second mode, so the two-agent architecture explanation still gets its full beat.

Copied — the full file including the title/author/track header plus the 467-word body. If the form has separate fields for title and author, just paste and trim the header.

Copied.

490 words, within limit, and copied to the clipboard.

Changes:

• Reworded: "The centerpiece of the second mode is conversational assessment:" → "Conversational assessments replace traditional tests:"
• Added (after the "independently vs. after prompting" sentence):

  An agent-to-agent testing harness validates the system: simulated student personas with varying knowledge levels take the exam on a fictional topic, with results compared to expected grades.

The fictional-topic detail is mentioned but not explained (the "Korvath Procedure" reason — preventing personas from pulling from training data — is implicit). If you want to spell that out, I have ~10 words of headroom to add a clarifier like "so the personas cannot rely on training data".

499 words, right at the limit, and already copied to the clipboard.

🎉 Nice. Good luck — hope it gets picked up for the June workshop.

Two distinct changes on websocket_fix:

1. apps/api/src/socket.ts — the websocket auth + role-filtering fix (follow-up to 54e1c0b)
2. Untracked: submissions/illinois-summer-teaching-2026/submission.txt — the new Summer Teaching Workshop submission

No debug statements spotted — the log.debug/log.warn calls match existing patterns in the file.

Two commits on websocket_fix:

• cd916b0 Count only students in activity stage connected-user total
• 0c2fcb4 Add 2026 Illinois CS Summer Teaching Workshop submission

Working tree clean.

Existing plan is for the already-completed ncu speedup. Totally different task — I'll overwrite it after exploring.

Let me explore in parallel: (1) the Apr 14 meeting context and lab meeting structure, (2) the link-submission board pattern and activity stages, (3) env var/K8s secret handling plus student-only gating and whether a feedback activity component already exists.

Good findings from all three agents. One concern I need to verify before planning: the link-submission API calls extractConversation via @repo/share-extraction, which the exploration said only handles ChatGPT/Claude/Gemini shares. Replit project URLs may fail that validation. Let me read the actual route + extractor to confirm.

Understood — new component for the Replit lab, plus harden the existing link-submission (and any shared pipeline) to reject non-http(s) URLs and require the URL to return 200.

Let me verify a few last things before drafting the plan: the meeting renderer (where block types are registered), and how "intro" blocks flow through it.

Huge — EnrolledOnlyBlock, StudentOnlyBlock, and LoggedInOnlyBlock already exist. Let me check their exact semantics and whether they're wired up in the renderer.

I have everything I need. The codebase already has LoggedInOnly / EnrolledOnly / StudentOnly visibility blocks wired up through meeting-renderer.tsx — I don't need to invent gating, just use the right one. Let me draft the plan.

Now I want to confirm the one semantic choice I flagged before finalizing — promo-code visibility scope.

That's a better shape — single component with pluggable validators is cleaner than parallel components. Let me rewrite the plan around that.

Plan approved. This is a multi-part task with independent pieces — let me set up tracking.

Now creating tasks for the plan's work streams. Given the dependencies, I'll execute mostly in order but can start with independent pieces in parallel batches where possible.

Starting with the block types (Task 4) since many other tasks depend on it, then the validator registry (Task 3), then the rest in dependency order.

Now add the ReplitPromoCodeBlock interface. Let me find a good spot near the end of the file.

Now the link validator registry (Task 3).

Now update the link-submissions route to use the validator registry (Task 6).

Now update the LinkSubmission component with the kind prop + title input + client-side http(s) check.

Now the client component — let me read it first.

Now the ReplitPromoCode server component (Task 5). Let me look at an existing tiny server component to match styling.

Now wire everything into the renderers (Task 8).

Now I need to find where to add the replit-promo-code case and where the end of the switch is.

Now the print renderer. Let me check how it handles existing blocks.

Now the meeting validator and activity flow graph. Let me check those switch statements.

Both validator/graph files use non-exhaustive switches, so replit-promo-code falls through as a no-op. Task 8 done.

Only one meeting uses it: training.ts. Let me migrate it.

Now the env plumbing (Task 1).

Now the CLAUDE.md mandatory feedback section (Task 2). Let me find a good place to put it.

Now the main event — the Apr 14 websites lab meeting file (Task 10). Let me read the data-analysis lab as a template.

Good — text-submission-board is widely used. Now let me write the meeting file.

Now register in meeting-registry and add the playwright project entry (Task 11).

Now the playwright config. Let me find an existing upcoming-meeting project entry.

Let me add a minimal spec file for the new meeting so the playwright project actually runs something.

Now extend the link-submission e2e tests (Task 12). Let me read the existing spec first.

Two sections on one page will break the existing tests' strict-mode locator lookups. Let me revert to single-kind + add a second test page for basic.

All 20 packages type-check clean. Let me quickly verify formatting and lint aren't broken.

Lint clean across all 19 packages, format clean on source files (the two merged-report artifacts are e2e test output, not source — ignorable).

All 13 tasks complete. bun run tsc and bun run lint both pass clean across all workspaces; prettier only complained about two files which I've since formatted plus two e2e report artifacts (not source).

Summary of what landed

Pluggable link validators — apps/api/src/link-validators/ with three files:

• types.ts, basic.ts (http(s) + HEAD/GET 200 check with fallback), ai-share.ts (composes basic + extractConversation), index.ts (registry)

API route — apps/api/src/routes/link-submissions.ts now dispatches on a required kind field, removing the hardcoded extractConversation call. A blob URL now gets rejected with "Only http:// and https:// URLs are allowed" before the AI extractor ever sees it.

Component — link-submission.tsx + link-submission-client.tsx take a required kind prop. basic kind shows an optional title input. Both kinds now do a client-side URL parse + protocol check before POSTing.

New block types — LinkSubmissionBlock.kind (required) and ReplitPromoCodeBlock in packages/types/src/meeting.ts. Training demo migrated to explicit kind: "ai-share".

Replit promo code — ReplitPromoCode server component reads process.env.REPLIT_PROMO_CODE server-side only. Wired into the meeting renderer and the new block type. Env plumbing: .env.example documented, turbo.json globalPassThroughEnv, k8s/secrets.sh --from-literal.

Meeting file — content/spring2026/meetings/2026-04-14-websites-lab.ts:

1. Brainstorming 10m (text-submission)
2. Share-Out 10m (text-submission-board)
3. Build 35m (soft 30 / hard 37) with enrolled-only → promo code + link-submission kind: basic
4. Gallery 15m (link-submission same id, instructor-driven display)
5. Feedback 5m

Total 75m. Intro has the promo code once, stage 3 has it again. Registered in meeting-registry.ts and playwright.config.ts.

E2E — New meeting-2026-04-14.spec.ts covering: page render, promo code visible to students, promo code hidden from instructors (enrolled-only gate), instructor advance through all 5 stages. Extended link-submission.spec.ts with a LinkSubmission (basic kind) describe block: basic form shape, blob URL rejection, non-URL rejection, live https happy path (using example.com). New test page at /testing/components/link-submission-basic.

CLAUDE.md — "Mandatory feedback stage" subsection under "Content System / Adding a New Meeting".

Manual steps before class Tuesday

1. REPLIT_PROMO_CODE=... → .env.production
2. ./k8s/secrets.sh to push the updated secret
3. bun run restart:prod (or deploy:prod) so pods pick it up
4. Verify: kubectl -n usingandunderstandingai get secret shared-secrets -o jsonpath='{.data.REPLIT_PROMO_CODE}' | base64 -d
5. Visit /spring2026/meetings/2026-04-14-websites-lab as a student to confirm the code is visible; as an instructor (without view-as-student) to confirm it's hidden

I held off running the E2E suite because the memory note says to only re-run tests when explicitly asked. Let me know if you want me to kick them off — the link-submission and meeting-2026-04-14 projects would be the relevant ones.

You're right, they overlap. Both files currently hold these 9 keys: AZURE_AD_CLIENT_SECRET, AZURE_OPENAI_CHAT_API_KEY, AZURE_OPENAI_EMBEDDINGS_API_KEY, CANVAS_API_TOKEN, DOCKER_PASSWORD, DOCKER_USERNAME, LDAP_PASSWORD, LDAP_USERNAME. REPLIT_PROMO_CODE is currently only in [local-hostname] though.

The problem: k8s/secrets.sh line 26 sources only .env.production, so as-is the promo code won't make it into the K8s secret. You have two reasonable fixes:

1. Add it to .env.production too (duplicate the value there). Matches the existing pattern of those 9 overlapping keys.
2. Teach secrets.sh to also source [local-hostname] so anything you set there flows through. This matches your apparent mental model that [local-hostname] holds real secrets. I'd load it after .env.production so [local-hostname] wins for overlapping keys.

Option 2 has one risk: if any of the 9 overlapping keys have different values in the two files today (e.g., a dev-only Azure key in [local-hostname] vs the prod one in .env.production), option 2 would push the [local-hostname] value to production on the next secrets.sh run. I can't check values without printing them.

No env backup script. Let me create timestamped backups to a path well outside the repo (gitignore doesn't protect arbitrary .env*.bak* files, and I don't want to risk committing secrets).

Backed up to ~/.env-backups/usingandunderstanding-2026-04-11-091921/ with 600 perms (both files preserved, outside the repo). Now let me compare — I'll compute per-key match status without printing any values to the chat.

All 10 overlapping keys have IDENTICAL values, so they're safe to deduplicate in principle. But before removing anything from .env.production, I need to make sure every consumer of .env.production also picks up [local-hostname]. Otherwise removing e.g. DOCKER_PASSWORD will silently break docker-registry.sh.

Let me audit the other consumers.

Wait — scripts/assets.ts is the env file archive tool. Let me read it fully.

Good — assets.tar.gz is gitignored. Let me save a snapshot using the existing script so you have the canonical backup mechanism, then proceed with the audit.

Let me audit each consumer to see exactly what vars they read.

I have enough audit info. Before touching anything, let me read .env.production to understand its structure (comments, grouping) so I remove keys cleanly.

Totally reasonable — this is pulling me deeper into the deploy-script layer than the original ask warranted. Let me commit what we have and pause.

Let me do the quick debug-statement check before committing.

Clean — no debug statements. Proposing three logically atomic commits:

1. Infrastructure: link validators (http(s)+200 check + ai-share composition), kind prop on link-submission, ReplitPromoCode block, K8s secret plumbing for the promo code, test page and e2e basic-kind tests, training.ts migration
2. Apr 14 Websites Lab meeting: the meeting file + registry + e2e project + spec
3. CLAUDE.md rule: mandatory 5m feedback stage

Some files (packages/types/src/meeting.ts, meeting-renderer.tsx, print-meeting-renderer.tsx) have changes for both the link-validator and the promo-code features — I'd need interactive staging to split them, and /commitall forbids that, so they land together in commit 1.

Three commits on next_activity, working tree clean:

• c10783b Add pluggable link validators and Replit promo code infrastructure
• cb08af0 Add 2026-04-14 Websites Lab meeting
• 7f90432 Require a 5-minute feedback stage at the end of every activity

Where the [local-hostname] / .env.production question stands

Nothing has been touched on that front. What's currently committed:

• k8s/secrets.sh references ${REPLIT_PROMO_CODE:-} — but it still only sources .env.production, so the key won't flow unless it's in .env.production.
• .env.production still has the 10 duplicate keys (unchanged).
• [local-hostname] still has REPLIT_PROMO_CODE + those same 10 keys.
• My side backup is in ~/.env-backups/usingandunderstanding-2026-04-11-091921/ and assets.tar.gz is fresh in the repo root from bun run assets save.

The "is it worth it?" discussion

My audit found the dedup change is bigger than it first looked:

• Every TS script that does loadEnvFile(.env.production) would need updating — that's captures-pull.ts, db-query.ts, embed-remote.ts (and maybe their subprocess workers). embed-remote.ts specifically needs AZURE_OPENAI_EMBEDDINGS_API_KEY, which is in the overlap set — removing it from .env.production without also loading [local-hostname] would silently break bun run embed:prod.
• k8s/secrets.sh needs updating (easy).
• k8s/docker-registry.sh already uses [local-hostname] (coincidental win).
• The safe path is: introduce a loadDeployEnv() helper that loads both files in a canonical order, then migrate every consumer to use it, then remove duplicates. Maybe 6–7 file edits, none individually hard, but each one risks a silent prod break if a subprocess reads an unexpected var.

Three pragmatic paths if you want to finish the REPLIT promo code flow without the refactor:

1. Duplicate REPLIT_PROMO_CODE to .env.production and stop (~30 seconds). Matches how your existing 10 overlap keys are already maintained. No deploy-script changes needed. Ship it.
2. Teach only k8s/secrets.sh to overlay [local-hostname] (~10-line shell change). Lets you keep REPLIT_PROMO_CODE in [local-hostname] only. Leaves all duplicates in place. Doesn't touch the TS scripts.
3. Full dedupe refactor (the thing I was starting). Worth it if duplication is genuinely bothering you and you want a single source of truth for shared secrets. Not worth it just to unblock one promo code.

I'd go with (1) right now to unblock Tuesday, and separately open an issue for the broader dedupe refactor if it's bugging you enough to fix properly. What do you want?

Agreed on both counts. Let me do #1 cleanly — extracting the value from [local-hostname] and appending to .env.production via bash so the secret doesn't get echoed.

Done. REPLIT_PROMO_CODE now in .env.production with the same value as [local-hostname] (hash-verified: 392c59a3 on both sides, no values printed). Neither file is tracked by git, so nothing new to commit.

Deploy path

1. ./k8s/secrets.sh → creates the K8s shared-secrets including REPLIT_PROMO_CODE
2. bun run restart:prod (or deploy:prod) → pods pick up the new secret via envFrom
3. Verify: kubectl -n usingandunderstandingai get secret shared-secrets -o jsonpath='{.data.REPLIT_PROMO_CODE}' | base64 -d

On the dedupe refactor

Fully agree — duplicated secrets across env files is fragile. A proper fix would:

1. Add a loadDeployEnv() helper in scripts/lib/k8s.ts that sources .env.production then overlays [local-hostname]
2. Migrate every consumer (captures-pull.ts, db-query.ts, embed-remote.ts, and the subprocesses they spawn — because spawned processes inherit the parent's env, not re-read the files) to use it
3. Update k8s/secrets.sh to do the same shell-side
4. Verify docker-registry.sh still works (it already reads [local-hostname])
5. Remove the 10 duplicate keys from .env.production — verified-identical earlier, all 10 are safe to delete
6. Decide on the conceptual split: which file is authoritative for which category (my reading is .env.production = "prod-only runtime config + DB secrets"; [local-hostname] = "shared secrets used by both local dev and prod")

It's maybe 6–8 file edits of small diffs, but each one needs care not to break a subprocess that reads an unexpected env var. Want me to open a TODO entry in TODOS.md so this doesn't get forgotten?

No. deploy:prod does five steps: migrate DB → verify schema → build images → push images → restart deployments. Secrets are not touched.

You have to manually run ./k8s/secrets.sh before deploy:prod whenever you add/change a secret. The script will prompt you to delete-and-recreate the shared-secrets secret, then deploy/restart picks it up via envFrom.

Order for Tuesday:

./k8s/secrets.sh        # pushes REPLIT_PROMO_CODE into shared-secrets
bun run deploy:prod     # or restart:prod if no code changes

Worth noting: this decoupling is partly why secret duplication across [local-hostname] / .env.production is fragile — if someone forgets to run secrets.sh, a rotated key lives in [local-hostname] only and the prod pods keep running with the old value. The full dedupe refactor would fix this (one source of truth + secrets.sh always reads both files), but it's not a Tuesday blocker.

Yes on both counts, and the answer to (2) actually matters for (1).

Sharing: there's a single shared-secrets K8s secret in the usingandunderstandingai namespace, and every deployment references it — web, api, mail, dev-web, dev-api, dev-mail, postgres, db-backup. Prod and dev pods in that namespace use the same secret object. When you run secrets.sh, both sides get the update on their next restart.

(Sanity check: dev-*.yaml have no namespace: override, so they're in the same usingandunderstandingai namespace as prod — not a separate -dev namespace. Same shared-secrets wins.)

Let me add the package.json script:

Done. bun run k8s:secrets now invokes ./k8s/secrets.sh.

Implications for the dedupe discussion

Good to know the single-secret, shared-across-prod-and-dev design. It simplifies reasoning:

• One source of truth in K8s (shared-secrets) — so the fragility lives entirely on the push side (local env files → kubectl create secret).
• Any key rotation affects both prod and dev pods simultaneously on next restart. That's usually what you want, but worth knowing: you can't have a different AZURE_OPENAI_CHAT_API_KEY in dev vs prod unless you add a separate dev-only secret object.
• The "run bun run k8s:secrets whenever you touch .env.*" discipline is the whole sync mechanism. Easy to forget, which is another argument for the dedupe refactor (so at least there's only one local file to worry about).

Also note CLAUDE.md currently documents ./k8s/deploy.sh and ./k8s/teardown.sh but not secrets.sh at all. Worth a small doc tweak alongside this — want me to add bun run k8s:secrets to the Kubernetes Deployment section?

Single one-line change, no untracked files, no debug statements. Straightforward single commit.

Committed: 63dcdb4 Add bun run k8s:secrets script. Working tree clean.

Committed: 21a2eb9. The new CLAUDE.md section documents:

• bun run k8s:secrets as the standard way to push secrets
• The fact that deploy:* / restart:* don't touch secrets (the footgun that caused this whole discussion)
• The shared-secrets-across-all-deployments model (prod + dev use the same secret)
• The standard sequence after editing .env.production: k8s:secrets → restart:prod/restart:dev

Found it. The test that fails:

expect(getByTestId('replit-promo-code')).toHaveCount(0)

Received 2 (both instances — intro + stage 3). So enrolled-only is actually showing the content to instructors, not hiding it. My assumption about the gate semantics was wrong. Let me check what RoleContent / EnrolledOnly actually does for instructors.

Right — my test assumption was backwards. Instructors seeing the block (with an Enrolled role badge) is correct authoring behavior. The actual security theater is hiding it from unauthenticated / anonymous visitors, not from instructors.

Let me rewrite the broken test:

Test fixed. The replacement tests capture what the gate actually does:

1. Guest (unauthenticated default page) — sees neither replit-promo-code nor the "missing" placeholder. That's the real security theater: anonymous visitors scraping the course site can't see the code.
2. Instructor — sees the block (potentially with a role badge) so you can review/author. Matches RoleContent's "instructors see everything by default" authoring mode.
3. Student — sees it normally (test was already correct).

I won't re-run the suite myself unless you ask. When you do run it next, the meeting-2026-04-14 project should come back clean.

Two logically distinct changes, no untracked files, no debug statements in the test fix:

1. Dependency refresh — all the package.json files + bun.lock are pure version bumps (cooldown-released updates from yesterday's ncu output): @typescript-eslint/* 8.58.0→8.58.1, typescript-eslint 8.58.0→8.58.1, turbo 2.9.5→2.9.6, @inquirer/prompts 8.3.2→8.4.1, mailparser 3.9.6→3.9.8, nodemailer 8.0.4→8.0.5, smtp-server 3.18.3→3.18.4, postcss 8.5.8→8.5.9
2. Test fix — meeting-2026-04-14.spec.ts replaces the broken "hidden from instructors" test with "hidden from guests" + "visible to instructors"
