From eb781fcad3b3e9d455c0d046e94d67f1998b91f0 Mon Sep 17 00:00:00 2001 From: Thomas Jung Date: Fri, 11 Sep 2026 08:38:40 -0700 Subject: [PATCH 001/138] fix(csrf): re-authenticate on a real 401 in a stale session (#2239) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-on to #1904. A stale session no longer always surfaces as the 200-HTML XSUAA login interstitial — AppRouter/CAP can now reject the mutating request (or the /auth/user handshake) with a genuine 401 Unauthorized. csrfFetch only treated a followed redirect or a 2xx-HTML body as session-expiry, so the 401 was returned to the caller; the tutorial Done button's apiPost saw res.ok === false, returned false, and reverted with no re-login (POST /api/completeStep 401 in the console). Treat a 401 as the stale-session tell in isSessionExpiredResponse so csrfFetch forces the same top-level /login?returnTo navigation and the OAuth redirect actually executes. 403 is deliberately excluded (CSRF retry signal / Akamai edge block) and the safe-method GET path is untouched, so read 401s (anonymous /auth/user, getProgress) still pass through. --- hugo-apps/src/shared/csrf-fetch.test.ts | 46 +++++++++++++++++++++++++ hugo/assets/js/csrf-fetch.ts | 22 ++++++++---- 2 files changed, 62 insertions(+), 6 deletions(-) diff --git a/hugo-apps/src/shared/csrf-fetch.test.ts b/hugo-apps/src/shared/csrf-fetch.test.ts index 823490cda..ef406259c 100644 --- a/hugo-apps/src/shared/csrf-fetch.test.ts +++ b/hugo-apps/src/shared/csrf-fetch.test.ts @@ -277,6 +277,52 @@ describe('csrfFetch', () => { } }) + // --- Stale-session re-auth via a real 401 (issue #2239) --- + // A follow-on to #1904: the stale session no longer always surfaces as a + // 200-HTML interstitial.

Rewrite relative image paths to absolute raw.githubusercontent.com URLs at serve time, using repo+branch from RepoCatalog (keyed by slug, populated on publish, covers live tutorials). This avoids the schema change / re-publish / backfill a publish-time fix would need, and keeps stored sourceContent pristine. Provenance is fail-open: no RepoCatalog row leaves image paths relative (pre-#2235 behavior). Mirrors the render-time rule in scripts/parsers/images.ts: skips absolute http(s) and ../ paths, strips leading ./ or /, resolves under tutorials// (covers both images/ subdir and flat abap layout).

Absent key ⇒ feature fails open (disabled), logged once. +- **`kid`** identifies the signing key in the JWS header. +- **Public keys** published as a JWKS document at `GET /.well-known/tutorial-provenance/jwks.json`, reusing the existing `.well-known` approuter-middleware seam (`docs/.../2026-08-28-well-known-oauth-discovery-design.md`).

Otherwise cache hits would silently drop the headers (this is the gotcha flagged during grounding). + +### E. Signing lifecycle + +Sign **on first serve**, cache the JWS keyed by `(contentHash, freshnessReportRunAt)`. Re-sign only when the content changes (new `contentHash`) or the freshness report changes (`runAt` advances).

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Re-land the CAP 10 HCQL ("CQL over HTTP") protocol adapter on the 5 authenticated services, mounted on distinct `/hcql/` paths so it never collides with OData — on a CAP 10.1.0 runtime with a coordinated package.json-wide (within-major) dependency refresh. + +**Architecture:** The 2024 re-land (#1002, reverted by #1004) failed because `annotate with @hcql` co-mounted HCQL on each service's existing OData `@path`, greedily parsing OData bodies/URLs as CQN (218 test failures). The fix, proven in the spike (spec §2), is twofold: (a) bump `@sap/cds` to `^10.1.0` (fixes OData `$filter` interception and the malformed-CQN process-exit DoS), and (b) give each enabled service an explicit object-form `@protocol` list that mounts HCQL on a distinct `/hcql/` path while keeping OData on its current `@path`. Dependency work is phased (CAP ecosystem first, then broader tree) so regressions are attributable. + +**Tech Stack:** SAP CAP (`@sap/cds` 10.1.0, `@sap/cds-dk` 10.1.x), Node.js 22, `@cap-js/*` plugin stack, `@cap-js/sqlite` (unit) / `@cap-js/hana` (hybrid), Vitest via `@cap-js/cds-test`, SAP approuter (`xs-app.json`), XSUAA. + +**Spec:** `docs/superpowers/specs/2026-09-11-2247-hcql-reland-design.md` + +## Global Constraints + +_Every task's requirements implicitly include this section._ + +- **CAP runtime floor:** `@sap/cds >= 10.1.0`. `@sap/cds-dk` pinned to same minor (10.1.x; 10.1.1 latest published). Keep cds/cds-dk minor-aligned. +- **HCQL is authenticated-only, never anonymous** — exactly these 5 services: AdminService, AuthorService, AnalyticsService, ExportsService, ConsolidationService. The 4 public services (graph/homepage/search/api) are OUT of scope. +- **OData `path` in every new `@protocol` list MUST equal the service's current `@path` verbatim** — a mismatch moves the OData URL and breaks every existing client. Exact values: `/admin`, `/author`, `/admin/analytics`, `/admin/exports`, `/api/v1`. +- **Object-form `@protocol` entries only** (`{kind, path}`). A bare-string array collapses all adapters onto one path and 404s OData (documented hazard in `srv/admin-service-mcp.cds`). +- **HCQL paths:** `/hcql/admin`, `/hcql/author`, `/hcql/analytics`, `/hcql/exports`, `/hcql/consolidation`. +- **Phase B dependency updates are within-major only** — any major-version jump is out of scope, deferred to a separate maintenance PR. +- **`NODE_AUTH_TOKEN` must be set** (`export NODE_AUTH_TOKEN="$(gh auth token)"`) before any `npm install`/`npm outdated`/`npm view` — the private `@sap-tutorials/*` GitHub registry needs it. In this worktree, edit-isolation blocks the `$(gh auth token)` substitution inside compound commands: set the env var in a standalone step first, or run dep work from the primary checkout. +- **CAP rules:** never write raw SQL (use `cds.ql`/CQL); never use `req.user` without `@requires`; never bypass `@requires`/`@restrict`. +- **Never rely on training data for package versions** — resolve every "to" version from npm at execution time (`npm view version`, `npm view versions --json`, `npm outdated`).

Adds a job + table + migration not needed for v1. +- **C — thin composition over existing endpoints.** Doesn't add topological ordering + (the actual gap) and duplicates logic across the in-product and MCP consumers. + +## Components + +### 1. Core reasoning module — `srv/lib/kg/learning-path.js` (net-new) + +Pure function, deterministic given a graph snapshot + learned set → unit-testable: + +``` +computeLearningPath({ goal, goalType, learnedConcepts, partialConcepts, graph }) + → { steps, meta } +``` + +`graph` is a plain in-memory snapshot (no DB access here): `requires` adjacency, +`teaches` links (tutorial↔concept), `partOf` membership, and per-tutorial ranks. + +Algorithm: + +1. **Resolve goal concept set G.** + - `tutorial` → concepts the tutorial `teaches`. + - `mission` / `group` → union of concepts taught by member tutorials (via `partOf`). + - `next-best` → G = ∅ (handled by step 6). +2. **Backward `requires`-closure** from G → candidate concept set **C** (goal concepts + ∪ transitive prerequisites). Bounded: max depth ≈ 6, max nodes ≈ 200; on overflow set + `meta.truncated = true` and keep the nearest-to-goal frontier. +3. **Subtract satisfied concepts:** `R = C − learnedConcepts`. Partial concepts stay in + `R` but are flagged `alreadyPartial`. +4. **Topological sort** of `R` over the `requires` sub-DAG via **Kahn's algorithm**. + Cycle-breaking: if Kahn stalls (a cycle remains), drop the **lowest-confidence** + `requires` edge in the remaining cycle, continue, and increment `meta.cyclesBroken`. +5. **Concept → tutorial mapping.** For each concept in topological order, pick the best + tutorial that `teaches` it — **highest `TutorialRank`, preferring not-yet-completed**. + Dedupe tutorials covering multiple concepts to their earliest position; drop tutorials + the learner already completed. +6. **`next-best` variant.** Frontier = unlearned concepts whose `requires` prerequisites + are all in `learnedConcepts` → map to tutorials, rank, take top 3–5. + +Output: + +``` +steps: [{ order, tutorialSlug, teachesConcepts[], satisfiesPrereqFor[], alreadyPartial }] +meta: { goalType, goal, totalSteps, cyclesBroken, truncated } +``` + +Defaults (overridable later, not in v1): cycle-break = drop lowest-confidence edge; +best-tutorial = highest rank, prefer incomplete. + +### 2. Graph-assembly adapter — `srv/lib/kg/learning-path-graph.js` (net-new) + +The only component that touches HANA. Assembles the `graph` snapshot the core needs +(`requires` edges, `teaches` links, `partOf`, ranks) from existing SPARQL procedures / +CDS reads. Uses raw `db.run()` for any LOB-adjacent reads (avoids the CDS-QL LOB-locator +expiry gotcha). Caches the **non-personalized** closure per `(goal, goalType)` with a +short TTL (via existing `cds-caching`) since it is identical across users; personalization +(the learned-set subtraction) is applied after the cache, per request. + +Keeping all dialect specifics here leaves the core dialect-agnostic and SQLite-testable +in unit tests. + +### 3. Endpoint & auth — `KnowledgeGraphService` + +Add an unbound CDS function to the existing service (`@requires: 'any'`): + +```cds +type LearningPathStep { + order : Integer; + tutorialSlug : String; + teachesConcepts : array of String; + satisfiesPrereqFor : array of String; + alreadyPartial : Boolean; +} +type LearningPathResult { + goalType : String; + goal : String; + totalSteps : Integer; + cyclesBroken : Integer; + truncated : Boolean; + personalized : Boolean; + steps : array of LearningPathStep; +} +function learningPath( goal: String, goalType: String ) returns LearningPathResult; +``` + +Handler: +- Authenticated learner → derive learned/partial via existing `conceptsForUser(req.user)` + logic, subtract at request time, set `personalized: true`. +- Anonymous → goal-only ordering, `personalized: false`. +- `goalType ∈ { tutorial, mission, group, next-best }`; unknown → 400. +- Gated by `KNOWLEDGE_GRAPH_ENABLED` master switch (existing `before('*')`) **and** the + new flag (§4). Fail-open: flag off → empty result, never a 500. + +### 4. Feature flag + +Register `KG_LEARNING_PATH_ENABLED` in `srv/lib/feature-flags/registry.js` as +`kind: 'db'` (backed by `KnowledgeGraphSettings.learningPathEnabled` or an `ImsConfig` +`flag.kg.learningPath` row), **DEV-only, default OFF, fail-open**. Must be registered so +it surfaces in the admin Feature Flags UI (per the registry drift-test guard). Update +`test/unit/feature-flags-registry.test.js` accordingly. + +### 5. In-product surface — Vue island (ships first) + +"Your Learning Path" island under `hugo-apps/`: +- Tutorial object page (`u1-object-page.html`) → "Path to this tutorial" (`goalType=tutorial`). +- Mission / group pages → "Complete this mission" ordering (`goalType=mission|group`). +- Standalone next-best widget deferred (see YAGNI). + +Island behavior: +- Login probe checks JSON + `body.authenticated` (not `r.ok`). +- Authenticated → personalized path; anonymous → goal-only path + "sign in to personalize" nudge. +- **Fail-open:** flag off / 503 / empty → island renders nothing; no layout break. +- Built + hashed through the normal island pipeline (`postbuild:apps` / island-manifest); + add to `npm run setup` if it needs deps not already present at root. + +### 6. MCP surface — phase 2 (same core) + +Add `kg_learning_path(goal, goal_type)` to the KG MCP service +(`srv/knowledge-graph-service-mcp.cds` + handler), wrapping the **identical** core module. +Non-personalized in agent context (no `req.user`) unless a caller supplies a user id. +Documented tool description ("Given a goal tutorial or mission, returns the ordered +prerequisite chain of tutorials to complete"). + +## Data flow + +``` +island / MCP tool + → learningPath(goal, goalType) [KnowledgeGraphService handler] + → learning-path-graph.js: assemble graph snapshot [HANA, cached non-personalized] + → conceptsForUser(req.user) [request-time, authenticated only] + → learning-path.js: computeLearningPath(...) [pure: closure → subtract → topo-sort → map] + ← { steps[], meta } +``` + +## Error handling + +- Master switch OFF → 503 (existing behavior). +- New flag OFF → `{ steps: [], meta: { ... } }`, fail-open (island renders nothing). +- Unknown `goalType` / missing `goal` → 400. +- Goal slug not in graph → empty `steps`, `truncated: false`. +- Cycle in `requires` → break lowest-confidence edge, `meta.cyclesBroken++`, never throw. +- Closure overflow → `meta.truncated: true`, return nearest-to-goal frontier. +- Graph-assembly failure → fail-open empty result + logged warning. + +## Testing + +- **Unit (pure core, dialect-agnostic):** fixture graphs covering a linear chain, a + diamond, a cycle (assert an edge is broken and ordering is still valid), learned-set + subtraction, all three `goalType`s, and the truncation bound. +- **Handler:** shape assertions, flag-OFF → empty, anonymous vs authenticated + (`personalized` toggles, subtraction applied), unknown `goalType` → 400. Use the + `cds.test('serve', …, '--in-memory')` pattern (not `cds.deploy(cds.model)`); put any + test-only hooks on `globalThis` so a `cds.serve()`'d handler sees them. +- No HANA-only reasoning in the core; graph assembly is mocked in unit tests. + +## YAGNI (out of scope for v1) + +- Difficulty weighting, time-based path optimization, editorial ordering overrides. +- Standalone `/learn-next` next-best page (start with tutorial + mission on existing pages). +- Precomputed/materialized ordering (Approach B). +- Persisting any per-user path or user→tutorial edge. + +## Rollout + +DEV-only behind `KG_LEARNING_PATH_ENABLED` (default OFF) + `KNOWLEDGE_GRAPH_ENABLED`. +Enable in DEV, verify all three shapes render and personalize, then decide on QA/PROD +exposure and MCP-tool publication (phase 2) separately.

The 5 /hcql/* routes set csrfProtection:false, tripping the guard. Per maintainer decision, remove the flag (approuter CSRF-on default) rather than allowlist HCQL — the secure default, and matches the security-bot MEDIUM finding. Consequence: clients must do the x-csrf-token: fetch two-step before each HCQL POST. Documented the handshake in hcql-support.md (curl intro + token fetch step + AdminService example + smoke-matrix note). Flipping back to the M2M csrfProtection:false pattern would require adding /hcql/* to CSRF_EXEMPT_SOURCES plus issue-tracker sign-off.
