Session Log: Spike 6 — AV Audit Correction And Client Proxy Generalization

Date: 2026-08-20 Participants: Than Grove, Claude Code Outcome: Corrects three independent errors in Spike 6's 2026-08-07 AV endpoint audit against live evidence, implements the client-side /proxy/json generalization in mandala-om (feat/generalize-json-proxy-all-sites, unmerged), and files a new scope gap in the Option A URL strategy: option-a-proxy-unavailable-on-standalone-deployments.md.

Summary

Session ran in parallel with Yuji's OAuth2 session-handling work (the fourth defect from 2026-08-19); nothing here touches that code path.

Started as: build the AV node-JSON controller. Became: a documentation correction, once it emerged that AV isn't migrated to D11 yet (no video-equivalent bundle, no mandala_kmassets_sync entry), so there was nothing to build a curated controller against. Than's call: fix the docs now, defer the code.

1. The 2026-08-07 AV audit row was wrong in three independent ways. That audit was done by reading D7 source rather than calling the live endpoint. Live curls against three real production video nodes (42016, 42167, 42158) showed:

Claimed (2026-08-07)	Actual (2026-08-20)
Served by `mediabase/mb_solr`, `mb_solr_get_solrdoc()`	Services module, per-content-type "JSON Path" setting
Bespoke Solr-derived flat `doc`	Augmented raw node, same family as Images/Sources/Texts
No JSONP	`.jsonp?callback=` returns 200 `text/javascript`; the client depends on it

Two consequences beyond the row itself: the believed Terraform/ALB server-rewrite requirement for AV doesn't exist (it's a normal Drupal route), and gotcha #4's "JSONP satisfiable on only 3 of 4 sites" is wrong — it's all four. Reliability caveat now flagged on the spike: the Sources and Texts rows come from the same source-read pass and have never been live-verified.

2. Client proxy generalization implemented (mandala-om e6e712ae, branched from release/v1.1.0-rc, unpushed). Widens the gate from Sources-only to all Drupal hosts. Two traps found in the process:

A widened substring test would have opened a spoofing hole. Broadening .includes('sources.mandala…') to .includes('mandala.library.virginia.edu') also matches mandala.library.virginia.edu.attacker.com. Verified both spoofs match the substring test and neither matches the URL()-parsed hostname test. 12 host-matching cases pass.
The AV .jsonp append had to move to the direct-JSONP branch only. A server-side proxy fetch of .jsonp returns mdldata({...}), which won't parse as JSON — this would have shipped as a silent, AV-only regression.

Verification is partial: node_modules isn't installed in that checkout, so the app test suite and prettier couldn't run. Syntax checked via node --check; host matcher unit-tested standalone. The proxy and JSONP request paths are unexercised and need a real browser check against a tibet build before merge.

3. New deferred note — Option A's scope is narrower than recorded. REACT_APP_WP_PROXY is defined in only 2 of 11 mandala-om env files (.env.tibet.prod, .env.tibet.staging). The proxy is a WordPress plugin; the standalone builds — including production mandala.kmaps.virginia.edu — have no /proxy/json at all and still make the direct cross-origin call that caused the 2026-07-29 Sources 503. This also withdrew an earlier suggestion made this session: the no-proxy fall-through looked like a bug worth failing loudly on, but it's load-bearing for exactly those deployments. Cheapest next step is checking whether the WAF actually fires on the standalone origin — never tested.

Also corrected mid-session: an earlier claim that the Sources proxy routing dated from 2026-08-12. It's 2026-07-29 (6a2ef22b), with the env rename 2026-07-30 (27a21c63), both by Than. 2026-08-12 was the URL-strategy decision and the SSRF fix.

Addendum — `mandala-om` has 8 phantom dependencies (found while trying to run the app)

Than installed mandala-om to browser-verify the proxy change and hit Module not found: Can't resolve 'date-fns'. Root cause is a repo-structure trap worth recording, since it will bite anyone else who tries to run this app:

mandala-om is two separate npm projects, not npm workspaces. The root package.json (mandala-om, 13 deps, exists for the root __tests__/ jest suite) and kmaps-app/package.json (kmaps-app, 62 deps, the actual CRA app) are independent. All app source lives in kmaps-app/src/.

Eight packages are imported from kmaps-app/src/ but declared only in the root package.json — someone ran npm install <pkg> from the repo root instead of from kmaps-app/. This only ever worked via Node's walk-up module resolution finding them in the parent node_modules. Install into kmaps-app/ alone and the build fails.

Package	Files importing it	Was
`date-fns`	2	absent → compile error
`iso-639-1`	6	absent → compile error
`iso-639-3`	6	absent → compile error
`react-image-magnify`	1	absent → compile error
`react-rnd`	1	absent → compile error
`react-split-pane`	2	absent → compile error
`react-tiny-popover`	1	absent → compile error
`react-router`	14	resolved as a phantom transitive dep of `react-router-dom` — worked by accident

All eight installed into kmaps-app/. react-router was additionally declared rather than left phantom; it moved 5.2.0 → 5.3.4 in the process, same-major but under 14 files.

Installing at caret ranges broke the build, and this is the durable lesson. The first rebuild failed with:

./node_modules/react-draggable/build/cjs/chunk-ACOTSM7X.mjs
Can't import the named export 'Children' from non EcmaScript module

react-rnd's caret (^10.3.7) let npm resolve 10.5.3, which requires react-draggable ^4.5.0 and pulled 4.7.1 — a post-ESM-transition build shipping .mjs chunks that this app's webpack 4 / react-scripts 3.4.3 cannot parse. Root's declared floor react-rnd@10.3.7 pins react-draggable to exactly 4.4.4, which predates that. Fixed by installing react-rnd@10.3.7 with --save-exact. Build then compiled successfully (with pre-existing ESLint/SASS warnings).

Generalize this before adding any dependency to mandala-om: on this toolchain, caret ranges are unsafe — anything published since the ESM transition may ship .mjs and fail the same way. Prefer the exact versions root declares. Three packages still sit above root's floor (iso-639-1 2.1.15, react-router 5.3.4, react-tiny-popover 8.1.6); the build passes with them, but they're the first place to look if something misbehaves at runtime.

kmaps-app/package.json + package-lock.json changes were left uncommitted — unrelated to the proxy change on that branch, so they want their own commit.

Not investigated: whether the root package.json's duplicated app deps (react, axios, react-router-dom, …) should exist at all, or whether the two projects should become real npm workspaces. That's a repo-hygiene question for whoever owns mandala-om packaging.

Addendum 2 — the host gate was redesigned, and two verification mistakes

Design change (mandala-om commit d83fa707). The first version of the host gate hardcoded the production domain, mirroring mandala-wp-proxy's server-side allowlist. Trying to actually test it exposed the flaw: dev's Drupal hosts are *-dev.internal.lib.virginia.edu, so the proxy branch could never fire in dev under any configuration — the change was untestable there by construction, and would break again at D11 cutover when the consolidated host changes. The gate now derives its host set from the REACT_APP_DRUPAL_* env vars each .env.* file already defines, which are the authoritative per-deployment list. Exact-hostname matching is retained (spoof case still blocked); non-URL vars like REACT_APP_DRUPAL_SOURCES_API drop out of the URL() parse, and REACT_APP_WP_PROXY isn't a DRUPAL_ var so the proxy can't self-proxy. 13 cases pass across simulated prod and dev env sets.

Verification mistake 1 — artifact presence is not build success. An earlier check in this session reported the build "succeeded" on the strength of freshly-written build/index.html and JS chunks. That reasoning is wrong: CRA emits build/ before the CI=true lint gate runs, so artifacts appear even on a failed build. The build had in fact exited 1. Correct method: read the exit code of an unpiped build (a piped exit code is the pipe's), or grep for Compiled successfully / Compiled with warnings / Failed to compile. Also: CI=true escalates this repo's 188 files of pre-existing lint warnings into hard errors, so it's the wrong flag for a smoke test here. Re-run without it: exit 0, "Compiled with warnings."

Verification mistake 2 — over-confident attribution of a runtime error. When a Sources page showed Error: Item not found!, this was asserted to be the node-JSON fetch, reasoning "the page frame loaded, so Solr succeeded." Than pushed back. He was right that the evidence was ambiguous: useSolr.js:58 uses the same logic/axios-jsonp adapter (with callbackParamName: 'json.wrf') that throws that exact string, so the message alone cannot distinguish the Solr call from the node-JSON call. The mechanism does distinguish them — script.onerror fires on HTTP/load failure, not on runtime exceptions in a script that loaded — and dev Solr returns 200 while dev Sources returns 404, so the original attribution held. But it was stated as fact before being checked.

Incidental bug found while checking (unrelated to this work): the dev Solr response comes back double-wrapped — testcb(testcb({...})). The PHP solr-proxy adds a callback wrapper on top of Solr's own json.wrf wrapper. Traced through the adapter: the inner call resolves the promise with correct data and restores window[jsonp] = old (undefined), so the outer call hits undefined(...) and throws an uncaught TypeError in the console. Harmless to the fetch, but every Solr call in the app emits a stray console error. Not filed yet.

Why dev cannot verify this change end-to-end: the dev Solr index's url_json values point at mandala-sources-dev.internal.lib.virginia.edu, which serves no JSON API at all — 404 on /sources-api/json/{nid}, /api/json/{nid}, /node/{nid} and /jsonapi; / returns Drupal 10/11 chrome.

Explained by Than (2026-08-20), and it is NOT a defect: all the *-dev.internal.lib.virginia.edu hostnames have been taken over by the new D11 site, so the D7 endpoints are simply gone there. This session initially wrote it up as breakage and nearly filed it as a deferred note; asking first avoided adding a non-issue to the queue. Staging still serves the D7 endpoints — e.g. mandala-sources-staging.internal.lib.virginia.edu/sources-api/json/62716.

Local testing therefore points at PRODUCTION, and cannot point at staging (decided by Than; caveat documented in the untracked .env.development.local). The reason staging is unreachable by config is worth remembering: the URL actually fetched is url_json, a field stored in the Solr record — not derived from REACT_APP_DRUPAL_*. Pointing at staging would need a staging kmassets index whose url_json carries staging hosts, and none is reachable (mandala-index-staging, mandala-solr-proxy-staging both fail to connect). Changing the DRUPAL_* vars only changes which hosts the proxy gate considers eligible. Production means read-only selects and GETs of public records — no write risk, negligible load, but live data.

Test ids are environment-specific: 62716 resolves on staging and production; 137238 resolves on production but not staging (older snapshot).

Addendum 3 — VERIFIED end to end in a browser, and two more findings

Than brought up the DDEV WordPress, which made a real browser test possible. Result: the full chain is verified for the first time on any codebase.

Request (Chrome, localhost:3000, production Solr + hosts)	Status
direct JSONP → `sources.mandala.library.virginia.edu/sources-api/json/25581?callback=…`	503 — the 2026-07-29 WAF bug, reproduced live
`localhost:3000/proxy/json/?url=…`	404 — gate works, but `setupProxy.js` was broken
`localhost:3000/proxy/json/?url=…` (after fix)	200, 4,677 bytes of real JSON

The Sources page then rendered its full record — title, journal, format, pages, year, record creator, visibility, complete abstract — where it had shown a blank body. No cross-origin request to the Sources host remains.

Finding A — setupProxy.js had never worked (mandala-om eeefb203). Express strips the /proxy mount path before http-proxy-middleware (v3.0.5) sees it, so the existing pathRewrite: {'^/proxy': '/proxy'} could never match — the prefix was already gone when it ran. Requests reached WordPress as /json/… and 404'd. Proven by deliberately doubling the prefix: /proxy/proxy/json/… → 200 while /proxy/json/… → a WordPress 404 page. This explains why the July 2026 Sources fix was only ever verified against production — local verification was impossible, and the failure looked like the feature rather than the dev tooling. The comment on the old rule (// ensure /proxy/ttt -> /proxy/ttt) shows the symptom had been noticed; the fix just doesn't hold under v3 + Express mounting.

Finding B — curl cannot test this WAF, and a third verification mistake. A curl replay with full browser headers (Origin, Referer, Sec-Fetch-Dest: script, Sec-Fetch-Mode: no-cors, Sec-Fetch-Site: cross-site, Chrome UA) returned 200 on the exact URL a real browser got 503 on. The rule keys on something header-spoofing can't fake — TLS/JA3 fingerprint, header ordering, or similar. On the strength of that false negative this session declared "the WAF doesn't reproduce today" and constructed a content-type/ORB theory to explain the failure instead. Both were wrong; the browser showed a plain 503. Rule going forward: only a real browser is evidence about this WAF.

Consequence for the Option A gap note: its first open question ("are the standalone deployments actually WAF-exposed?") is now substantially answered — the 503 came from localhost:3000, an origin with no relationship to thlib.org, so the rule is not origin-scoped to the WordPress embeds. The standalone deployments should be treated as genuinely exposed. Priority on that note raised accordingly.

Addendum 4 — a regression I introduced, and the rule that prevents it

Fixing the phantom dependencies broke every browse/list page (/sources/all/list, /images/all/list, and by implication all asset types). Symptom:

TypeError: Cannot read properties of undefined (reading 'match')
  useParams → const match = useContext(RouterContext).match;
  AssetHomeCollection.js:15 → const { view_mode } = useParams();

useContext(RouterContext) returning undefined is the signature of two copies of react-router in the tree — the context the <Router> provider fills is not the one useParams reads.

Cause: declaring the previously-phantom react-router at the root's range (^5.2.0) let npm resolve it to 5.3.4 at top level, while react-router-dom@5.2.0 pins react-router: 5.2.0 exactly and therefore kept its own nested 5.2.0 copy. Two instances, two distinct RouterContext objects.

node_modules/react-router                          → 5.3.4   (added by the "fix")
node_modules/react-router-dom/node_modules/react-router → 5.2.0   (what <Router> uses)

Fix: react-router pinned to exactly 5.2.0, matching what react-router-dom already resolved. One copy remains; all three pages verified rendering afterwards (26,429 Sources hits / 108,084 Images hits / the Sources detail record).

The generalizable rule — this is the second time the same class of mistake bit today. When converting a phantom dependency into a declared one, pin it to exactly the version already resolved in the tree, not to a range. A range is not "the same dependency written down"; it invites a different resolution, and for a library carrying React context (react-router, react, react-dom, anything with a provider/consumer pair) a duplicate instance is a silent runtime break, not a version warning. The earlier react-rnd failure was the same shape — a caret pulling a newer transitive react-draggable — and the risk had even been flagged in the commit message for react-router ("moved 5.2.0 → 5.3.4, same-major but under 14 files") without acting on it.

Still unpinned and above the root's floor: iso-639-1 (2.1.15) and react-tiny-popover (8.1.6). Neither carries React context and both build clean, but they're the remaining candidates if something else surfaces.

Where things stand at session end

Both branches pushed, both working trees clean, no PRs opened (Than's call — no PR yet on the docs branch).

Repo	Branch	State
`uvalib/mandala-navina`	`feat/av-node-json-controller`	15 doc commits, pushed. Branch name is a misnomer — no controller was built; it is entirely documentation
`shanti-uva/mandala-om`	`feat/generalize-json-proxy-all-sites`	4 commits, pushed, off the D7 branch `release/v1.1.0-rc`

mandala-om commits: e6e712ae generalize the gate → all Drupal hosts · d83fa707 derive hosts from REACT_APP_DRUPAL_* · eeefb203 fix setupProxy.js · plus the phantom-dependency declaration with two load-bearing exact pins.

Verified

The same-origin proxy path, end to end in a browser — the first time on any codebase. 503 direct → 200 through the proxy → Sources detail page renders its full record.
Sources browse (26,429 hits) and Images browse (108,084 hits) render after the react-router pin.
AV's /api/v1/media/node/{nid}.json and .jsonp behaviour, against live production.

NOT verified — the honest list

AV, Images, Texts and Visuals detail pages. Only Sources was exercised.
The AV direct-JSONP fallback specifically — the exact code that was moved in e6e712ae. It was reasoned about, never run. Given this session's record on reasoning (see below), that is the first thing to check before merge.
The Solr double-callback-wrap claim. Observed in curl; a corresponding browser console error was never found, so the claim that "every Solr call emits a stray TypeError" is unsubstantiated. Not filed as a deferred note for that reason.

Environment left running

Dev server on :3000 with REACT_APP_WP_PROXY=/proxy, pointed at production Solr and Drupal via the untracked .env.development.local (caveat documented inside the file). DDEV WordPress at thlddev.ddev.site up. Delete .env.development.local to revert — but that returns local dev to hosts where detail pages cannot render at all.

Five verification mistakes made this session

Recorded because each would mislead the next person the same way:

Artifact presence read as build success — CRA emits build/ before the CI=true lint gate, so artifacts appear on failed builds.
"Item not found!" attributed to the node-JSON fetch as fact before checking; useSolr uses the same JSONP adapter and throws the identical string. Than pushed back and was right that the evidence was ambiguous (the attribution happened to be correct on mechanism).
curl treated as a proxy for a browser against the WAF — a header-spoofed replay returned 200 where the real browser got 503, and a whole content-type/ORB theory got built on that false negative.
A caret range shipped for react-router, breaking every browse page via duplicate React context — with the risk named in the commit message and not acted on.
The dev-host 404s written up as breakage — they are expected fallout of the D11 takeover of *-dev hostnames. Asking Than first avoided filing a non-issue.

The throughline: reasoning was repeatedly substituted for evidence, and piped exit codes and build artifacts were repeatedly mistaken for verification.

assess where we are

Claude — 2026-08-20 13:48

Working tree is clean and up to date with origin/main. Now let me read the orientation docs to catch up on where things stand.

Claude — 2026-08-20 13:48

This is great — Yuji (not me) has been driving today's OAuth2 debugging session. Let me read the full latest session log to get the complete current picture, especially the newly-found fourth defect.

Claude — 2026-08-20 13:48

Where things stand

Repo: clean, up to date with origin/main @ a498be5. Yuji drove the last two sessions (2026-08-19), not you — worth knowing before assuming continuity.

Sprint 1 (Images) — 1b.3 OAuth2 authenticated path is deep in a debugging chain, 3 of 4 defects resolved:

✅ solr-proxy wasn't sending Authorization: Bearer on UserInfo calls — fixed (PR #121), deployed, verified live.
✅ OAuth2 signing keys weren't persisted across deploys — fixed via Ansible bind-mount (PR #122 area, terraform-infrastructure), verified live.
✅ openid scope granted zero permissions (simple_oauth's Oauth2AccessPolicy intersects real permissions with scope-granted ones; openid is umbrella:true so its own granularity config was dead code) — root-caused, fixed by setting umbrella:false directly via drush config:set on dev-0, confirmed correct against a real live token (PR #125).
🔴 Open, not yet root-caused: with the scope fix live, /oauth/userinfo still doesn't return JSON — instead there's a redirect loop (TooManyRedirectsException after 5 hops) with watchdog logging repeated Session closed for [uid 600] / session_destroy(): Trying to destroy uninitialized session. Looks like Drupal's session layer treating a stateless Bearer-authenticated request as a logout event. This is the designated starting point for the next session — deliberately left uninvestigated at end of a long session.

Once #4 is fixed, the next and reportedly last unproven link in 1b.3 is the proxy's Redis visibility-token read for a real OAuth2-authenticated session.

Other live threads worth knowing about: - docs/deferred/images-missing-interactive-viewing-surfaces.md — flagged for team discussion after Sprint 1 closes (OpenSeadragon viewer, sibling carousel, masonry gallery — none exist in D11 yet). Not a blocker. - A small housekeeping commit (a498be5) just landed redacting the real name of the test user (uid 600) from public docs per the private/public docs split convention. - Longer-standing high-priority open items still sitting in the deferred queue: d7-editor-permissions-og-group-scoped-not-migrated.md, authenticated-contributor-crud-not-wired-in-d11.md, staging-migration-execution-prerequisites.md, d7-shared-user-database.md — none touched this week.

If you want to pick up the session-handling redirect loop (defect #4), I can start there — it likely needs stepping through Drupal core's SessionManager to find what's triggering session_destroy() on a stateless Bearer request. Let me know if that's the target.

what's the login to dev simplesaml, u/n staff but what's the password

Claude — 2026-08-20 13:58

Found it — it's SimpleSAMLphp's standard test IdP fixture, documented in docs/deferred/dev-0-needs-test-idp-for-saml-login-testing.md:

Username: staff Password: staffpass

This is one of three canned example-userpass test identities (student:studentpass, staff:staffpass, faculty:facultypass) — SimpleSAMLphp's built-in no-real-IdP-needed test mechanism, gated on SIMPLESAML_ENABLE_EXAMPLE_AUTH, used against dev-0's default-sp. The staff identity is the one linked to the real migrated non-admin private-collection user (uid 600) via ExternalAuth::linkExistingAccount().

User — 2026-08-20 14:22

So Yuji is looking in to the login issue. What is something I can work on on my own?

Claude — 2026-08-20 14:22

Good candidate, and it's entirely independent of Yuji's session-handling debugging. Given your ownership, here's what fits best:

Spike 6 (API compatibility) — several unstarted, self-contained pieces, all yours already: 1. Sources/Texts/AV node-JSON controllers — each D7 site has a materially different response shape (AV has no Drupal route at all today, bespoke Solr-derived flat doc; Texts embeds rendered HTML via views_embed_view()). Building these follows the exact pattern you already proved for Images (mandala_node_api, PR #101). 2. Client-side generalization — useMandala.js currently only routes sources.mandala.library.virginia.edu through the proxy path; needs to route all sites. 3. Validate the Images response shape against the live React client's actual field usage — the current shape was a first draft, never checked against mandala-om's real consumption. 4. Texts embed endpoint (node_embed) + /general/api/user/current — identified as in-scope, not yet audited.

None of these touch OAuth2/session/solr-proxy code, so zero collision risk with Yuji's work.

Other options if you'd rather not do Spike 6 right now: - d7-editor-permissions-og-group-scoped-not-migrated.md (High priority, migration/access) — D7's real editor permissions are per-collection via OG group roles, not the sitewide content_editor role D11 currently has; needs design work. - Spike 4b's production transform (texts-footnotes-production-transform.md) — the footnotes spike is proven, this is the actual build-out for the Texts migration whenever that track starts.

Want me to start on one of the Spike 6 items — I'd suggest the AV or Sources node-JSON controller since those are the biggest unstarted gaps?

User — 2026-08-20 14:25

Start on the AV node-JSON controller issue but let's do it in our own branch for now, as we may not finish today. Also, I think I already told you that AV uses Services to create it's JSON API and the all the API endpoints for each asset type are registered as a setting for that content type in its admin page. You can look at the old AV Video content type at https://av.mandala.library.virginia.edu/admin/structure/types/manage/video and see it's "JSON Path" setting is 'api/v1/media/node/NID.json'

Claude — 2026-08-20 14:26

Got a live sample. Let me pull the full response and try a couple more nodes to see field variety (kmap terms populated, transcript, etc.)

Claude — 2026-08-20 14:27

Before I build the controller, I found something important that changes the picture — worth flagging before I write code against the wrong assumption.

I pulled three live JSON responses directly from av.mandala.library.virginia.edu/api/v1/media/node/{nid}.json (nodes 42016, 42167, 42158). They're raw D7 node dumps (vid, uid, title, field_pbcore_*, field_kmap_terms with the familiar raw/id/header/domain/path shape, field_og_collection_ref, etc.), plus a few computed extras (thumbnail_url, duration, path). This matches exactly what you described — a Services-module endpoint driven by the content type's "JSON Path" setting.

That contradicts the existing audit in docs/spikes/spike-06-api-compatibility.md, which currently says AV's endpoint is a "Solr-derived flat doc" served by mb_solr_get_solrdoc() with no real Drupal route — i.e. it claims a totally different shape and origin module. That earlier finding was based on reading D7 source, not hitting the live endpoint, and it looks wrong. I'll correct that doc as part of this work regardless.

The bigger issue: AV hasn't been migrated to D11 at all yet (no shanti_video-equivalent content type, no fields, not in mandala_kmassets_sync.settings.yml's bundle list — Images is still the only migrated site, per ADR 009's sequencing). So there's no bundle/field set to build a curated controller against yet, the way NodeJsonController::buildData() does for shanti_image.

Claude — 2026-08-20 14:30

Now the "AV is the exception" paragraph:

Claude — 2026-08-20 14:30

Now let me add a new subsection documenting the live AV field inventory as evidence/reference for whenever the AV migration is actually scoped.

Claude — 2026-08-20 14:31

Now let me clean up the temp JSON files and commit this doc-only fix on the branch.

Claude — 2026-08-20 14:31

Committed on feat/av-node-json-controller, not pushed yet.

Summary: Corrected the Spike 6 audit doc's AV entry — it previously claimed AV serves a Solr-derived flat doc via mb_solr with no real Drupal route. Live evidence (three curls against real production nodes) shows it's actually an augmented raw node via the standard Services-module content-type "JSON Path" setting, same mechanism as the other three sites — matching what you told me. Also captured a field inventory (PBCore paragraphs, KMaps term references, field_video/Kaltura, collection ref, a field_pbcore_description double-encoding oddity worth a second look) as reference for whenever AV migration actually starts, since no bundle/fields exist in D11 yet.

Didn't touch any Drupal code, per your call — building the controller itself is blocked on the AV migration being scoped (content type, field names). Left on the branch, uncommitted push, so you can pick this up or redirect. Want me to push the branch, or keep going toward opening a PR for just the doc fix?

User — 2026-08-20 14:34

Is there something else in this spike?

Claude — 2026-08-20 14:34

Found two more stale references to the old (wrong) AV claim further down — let me fix those too while I have the context loaded.

Claude — 2026-08-20 14:35

Yes — several unstarted items in this spike, and most are self-contained (no dependency on AV/Sources/Texts migration or on Yuji's OAuth2 work):

Generalize the client's proxy gate (useMandala.js in mandala-om) — currently only routes sources.mandala.library.virginia.edu through mandala-wp-proxy's same-origin /proxy/json. The server side is already generic and hardened; this is pure client-side work in a separate repo. Directly named as the spike's "remaining work" #1.
Validate the Images response shape against the live client — NodeJsonController's curated shape was built from the D7 audit + kmassets logic, never checked against what mandala-om's detail view actually reads out of the response. Could turn up mismatches before the pattern gets reused for other sites.
Audit the Texts embed endpoint (node_embed, reached via url_ajax) and /general/api/user/current — both identified as in-scope, neither audited yet for response shape.
Confirm whether the browse-by-KMap / generic AJAX endpoints have any remaining consumer — the React client doesn't use them, but the WordPress wp-kmaps plugin and other server-side consumers are unaudited. Needed before formally dropping them from the D11 requirement.
End-to-end node-ID preservation check — field_legacy_nid is assumed correct across migration but never verified against real url_json values end-to-end; the Images endpoint now surfaces legacy_nid so this check is possible but hasn't been run.

Of these, #1 (client proxy generalization) is probably the highest-value next step since it's explicitly called out as the last piece of the decided URL-strategy work. Want me to start there, still on this branch?

Describe what you mean by #1

Claude — 2026-08-20 14:35

Here's the concrete picture, based on what the spike doc's audit found in the mandala-om React app (I don't have that repo cloned locally, so this is from the documented findings, not a fresh read):

What exists today: The React app fetches each asset's detail JSON from the URL in its Solr record's url_json field. Since 2026-08-12, mandala-om's useMandala.js will route that fetch through mandala-wp-proxy's same-origin /proxy/json endpoint (avoiding the WAF cross-origin block that broke Sources) — but only when the URL matches sources.mandala.library.virginia.edu. It's a hardcoded substring gate, not a general rule. Everything else (Images, AV, Texts, Visuals) presumably still tries a direct cross-origin fetch, which is exactly the pattern that triggered the WAF 503 for Sources in the first place.

What "generalize the gate" means: widen that check so any url_json value — regardless of which of the five sites it points at — gets routed through the proxy, not just Sources'. Since the proxy's server-side handler (json_proxy in mandala-proxy.php) is already fully generic ($base_url = $params['url']; wp_remote_get($base_url);, now with the host allowlist), no server-side change is needed — it already accepts any Mandala host. The work is entirely in that one client-side conditional.

Why it matters: this is the last unfinished piece of the URL-strategy decision (Option A) the team already made on 2026-08-12. Until it's generalized, only Sources actually benefits from the fix; Images (now that mandala_node_api is live) and any future AV/Texts/Sources endpoints are still exposed to the same WAF block that caused the original incident.

Caveat: I haven't seen the actual useMandala.js source — I'd need to clone mandala-om to find the exact line and confirm the gate is really a plain substring check versus something more structured. Want me to go find and clone that repo so I can point to the real code before making the change?

Ok review where we are and tell me what's left to do in Sprint 6.

Claude — 2026-08-20 14:38

Assuming you mean Spike 6 (API compatibility) — there's no Sprint 6; sprints here are Sprint 1 with 1a/1b sub-steps.

Branch state: feat/av-node-json-controller has two doc commits from today (the AV audit correction), not yet pushed.

Against the spike's own four pass criteria

#	Criterion	Status
1	All 8 D7 API response formats documented	◐ JSON done for all 4 sites (AV corrected today); all 4 AJAX endpoints unaudited
2	URL strategy agreed	✅ Done 2026-08-12 — Option A, generalized
3	Feasible in D11 + Terraform ALB config	✅ Done — and Option A needs no ALB/WAF change; today's AV correction removed the one believed piece of Terraform work (the server-rewrite that turned out not to exist)
4	D11 implementation approach clear per endpoint	◐ Images built + live-verified; everything else unbuilt

Actionable now (not blocked on any migration)

Generalize the client proxy gate — useMandala.js still routes only Sources through /proxy/json. Last piece of the decided Option A. Needs mandala-om cloned (not on this machine).
Validate the Images response shape against the live client — NodeJsonController's curated shape was never checked against what the React detail view actually reads. Should happen before the pattern is reused for other sites. Also needs mandala-om.
Audit the AJAX endpoints — Texts' node_embed (the only one the client uses) and /general/api/user/current (used, but missing from the 8-endpoint matrix). D7 source appears to be local at ~/Sandbox/Mandala/Site/, so this is a source-read, no clone needed.
Confirm the browse-by-KMap endpoints have no remaining consumer — React doesn't use them, but wp-kmaps and server-side consumers are unaudited.
End-to-end nid-preservation check — field_legacy_nid assumed correct, never verified; the Images endpoint now surfaces legacy_nid, so the check is finally possible.

Blocked on other work

Sources/Texts/AV controllers — each blocked on that site's migration (ADR 009 sequencing puts Images first, AV last). Today confirmed AV's D11 bundle doesn't exist yet.
Identity forwarding through the JSON proxy — deliberately deferred 2026-08-12; private-collection assets unreachable via the React detail view.

One inconsistency I noticed while reading

The Spike 2 pre-findings section (line ~447) states "D11 needs equivalent [browse-by-KMap] endpoints", but the later 2026-08-07 client audit concluded they're not consumed and likely don't need reproducing. Those two claims sit in the same document unreconciled. Item #4 above is what settles it — worth resolving explicitly rather than leaving both statements standing.

Of the actionable set, #3 is the only one I can start immediately without cloning anything. Want me to take that, or clone mandala-om and go after #1/#2?

User — 2026-08-20 14:39

when you say 'useMandala.js still routes only Sources through /proxy/json' when was this implemented?

Claude — 2026-08-20 14:40

2026-07-29, in mandala-om (branch release/v1.1.0-rc) — commits 6a2ef22b and 27a21c63. It was the same-day mitigation for the live Sources WAF-503 incident, not planned spike work.

What each commit did, per the doc's source refs: - 6a2ef22b — the Sources 503 → /proxy/json routing itself - 27a21c63 — split REACT_APP_WP_PROXY out from the pre-existing geoserver env var

The mechanism: {REACT_APP_WP_PROXY}/json/?url=<encoded target> via a plain axios.get instead of JSONP, so the browser request is same-origin and the WordPress plugin does the cross-origin fetch server-side. Config REACT_APP_JSON_PROXY=/proxy/json?url=, with kmaps-app/src/setupProxy.js proxying /proxy/* to DDEV WordPress for local dev. Verified at the time against #/sources/127668.

Two clarifications worth making:

I misspoke earlier. In an earlier message I said this routing existed "since 2026-08-12" — that's wrong. 2026-08-12 was the URL-strategy decision and the mandala-wp-proxy SSRF fix. The client-side Sources routing predates it by two weeks.

The characterization of the gate as a substring check is a separate, later observation. The specific claim that useMandala.js gates on query.includes('sources.mandala.library.virginia.edu') was recorded 2026-08-12, in the "Implementation reality" section, while tracking down the proxy plugin. So the implementation is 07-29; the note about how narrowly it's scoped is 08-12.

Worth noting the sequencing: the code came first as a stopgap, and the spike's Option A decision (2026-08-12) retroactively ratified it as the permanent architecture — which is exactly why generalizing it is now "finish the decided thing" rather than new design work.

All of the above is from the spike doc's own records, not from my reading the code — mandala-om isn't cloned on this machine. If you want the commits confirmed as describing what actually shipped, I'd need to clone it.

User — 2026-08-20 14:41

Mandala-om can be found at: /Users/ndg8f/Sandbox/Mandala/Standalone/mandala-om

Claude — 2026-08-20 14:42

Confirmed against the real code. Three things:

1. Your dates — slightly different from what I said. Both commits are yours (ThanGrove <than@virginia.edu>): - 6a2ef22b — Wed Jul 29 2026, 14:16 — "Fix source pages: route sources JSONP body fetch through /proxy/json" - 27a21c63 — Thu Jul 30 2026, 06:20 — the env var rename (next morning, not same day as I implied)

2. The substring-gate characterization is accurate, useMandala.js:28:

if (query.includes('sources.mandala.library.virginia.edu')) {

One nuance the spike doc doesn't capture: it's not a hard switch. If REACT_APP_WP_PROXY is unset, the proxy branch falls through to the direct JSONP path anyway (lines 29–35). So an env misconfiguration silently reverts Sources to the broken direct fetch rather than failing loudly.

3. New finding — the doc's AV JSONP claim is also wrong. The table says AV has JSONP: "No (plain drupal_json_output)", and gotcha #4 concludes the client's JSONP dependency "is only satisfiable on 3 of the 4 today." Live:

GET /api/v1/media/node/42016.jsonp?callback=mdldata
→ HTTP 200, content-type: text/javascript, body: mdldata({"vid":"42016",...})

AV supports JSONP fine. And useMandala.js:78-80 depends on it — it appends 'p' to turn .json into .jsonp for asset_type === 'audio-video'. So that's the third error in the AV row from the same 2026-08-07 source-reading pass.

This matters for the generalization work. Widening the substring check isn't the whole job — that AV .jsonp special case has to go too, since a server-side proxy fetch doesn't need JSONP at all and would receive a text/javascript callback wrapper it can't parse as JSON. So generalizing is: widen the gate, drop the AV p append, and decide whether the silent fall-through should stay.

Let me fold the JSONP correction into the AV fixes already on this branch:

Claude — 2026-08-20 14:43

Three commits on the branch now, all doc corrections to Spike 6, none pushed.

Answering your original question: the Sources proxy routing was implemented by you on 2026-07-29 (6a2ef22b), with the env var rename the next morning, 2026-07-30 (27a21c63).

What reading the actual code changed:

The 2026-08-07 AV audit row now has three confirmed errors, all from reading D7 source instead of hitting the live endpoint — wrong module (mb_solr vs Services), wrong response shape (Solr flat doc vs augmented raw node), and wrong JSONP status (none vs .jsonp?callback=, which the client actively depends on). That's a pattern worth noting for the remaining Sources/Texts audit rows, which came from the same pass and haven't been live-checked.

And the generalization job is bigger than "widen the substring check": 1. Widen the host gate (the easy part) 2. Drop the AV 'p' append — otherwise the proxy gets mdldata({...}) back and can't parse it as JSON 3. Decide the fall-through: right now an unset REACT_APP_WP_PROXY silently reverts to the 503-ing direct fetch instead of erroring

Item 2 is the one that would have bitten during implementation — it's invisible until you actually try AV through the proxy.

Want me to make that client-side change in mandala-om now? It's a small, contained edit to one file, though it lands in a different repo than this branch, so it'd need its own branch and PR over there.

User — 2026-08-20 14:45

yes, make the change in mandala-om

Claude — 2026-08-20 14:46

Found something important before writing code: REACT_APP_WP_PROXY is set in only 2 of 11 env files — .env.tibet.prod and .env.tibet.staging. The standalone builds (.env.production → mandala.kmaps.virginia.edu, plus .env.uf, .env.cj, .env.contport, .env.development) have no WordPress, so no /proxy/json exists for them at all.

That means the fall-through I flagged as a possible bug is actually load-bearing — non-WordPress deployments legitimately must use direct JSONP. Making it "fail loudly" would break them. I'll keep it and design around it.

Claude — 2026-08-20 14:47

All 12 cases pass. Worth noting the comparison at the bottom: had I just widened the substring test to .includes('mandala.library.virginia.edu'), both spoof hosts would match — so the URL() parse isn't gold-plating, it's fixing a hole the naive generalization would have opened.

Claude — 2026-08-20 14:48

Done — committed to feat/generalize-json-proxy-all-sites in mandala-om, branched off release/v1.1.0-rc. Not pushed.

What the change does: widens the proxy gate from Sources-only to all five Drupal hosts, so Images/AV/Texts/Visuals stop making the direct cross-origin JSONP call that WAF-503s.

Three things that weren't obvious from the doc:

The naive generalization would have opened a spoofing hole. Widening .includes('sources.mandala…') to .includes('mandala.library.virginia.edu') matches mandala.library.virginia.edu.attacker.com — I verified both spoof cases match under the substring approach and neither does under URL() hostname parsing. The proxy's server-side allowlist is still the real guard, but the client shouldn't be handing it attacker-controlled URLs.
The AV .jsonp append would have broken AV specifically. It had to move into the direct-JSONP branch only — a proxy fetch gets mdldata({...}) back, which won't parse as JSON. This is the one that would have shipped as a silent AV-only regression.
The fall-through stays. REACT_APP_WP_PROXY exists in only 2 of 11 env files; the standalone builds have no WordPress at all. My earlier suggestion to make it fail loudly was wrong — I withdrew it.

Verification is partial. node_modules isn't installed in that checkout, so I couldn't run the app's test suite or prettier. I confirmed syntax via node --check and unit-tested the host matcher standalone against 12 cases (all passing). The proxy and JSONP request paths themselves are unexercised — worth a real browser check on a tibet build before merging.

One thing this surfaces for Spike 6: Option A as recorded says "generalize the same-origin proxy to all apps," but the proxy is a WordPress plugin and 9 of 11 deployments have no WordPress. So Option A covers the thlib.org embeds only — the standalone mandala.kmaps.virginia.edu build has no proxy path available and remains WAF-exposed. The spike doc doesn't acknowledge that gap. Want me to file it as a deferred note?

User — 2026-08-20 14:59

Please note all these things in the appropriate place in the docs, the session log, and your memory

Now the deferred README index table:

Now the session log:

Claude — 2026-08-20 15:02

Now memory — updating the Spike 6 memory and the project state memory:

Claude — 2026-08-20 15:03

Now marking the superseded AV claim in the older section of that memory:

Claude — 2026-08-20 15:03

Let me address that build error — you're blocked.

Claude — 2026-08-20 15:03

Found it — and it's not caused by my change (that touched only useMandala.js).

Root cause: this repo is two separate npm projects, not workspaces:

Root package.json (mandala-om, 13 deps) — declares date-fns ✅
kmaps-app/package.json (kmaps-app, 62 deps) — does not declare date-fns ❌

But the files importing it live in kmaps-app/src/: - src/catalog/biblrecord/BiblMetadata.js:2 — import { format } from 'date-fns' - src/views/Terms/TermDictionaries/TermDictionaries.js:21 — import { km } from 'date-fns/locale'

You installed into kmaps-app/ only — root node_modules is absent. Node/webpack resolution walks up the directory tree, so previously date-fns resolved out of the root node_modules. Without it, the import dead-ends. That's a latent packaging bug that only shows when root isn't installed.

Two fixes:

Claude — 2026-08-20 15:04

The date-fns dep landed in the root package.json during commit 382af4d9 ("migrating more of catalog components") — almost certainly npm install date-fns run from the repo root instead of from kmaps-app/. Root also carries duplicate app deps (react, axios, react-router…) for its jest suite, which is why the mistake went unnoticed.

Installing it where it's actually imported — pinned to ^2.30.0 to match root, since date-fns v3/v4 have breaking changes to format and to date-fns/locale import paths that would break both call sites:

Claude — 2026-08-20 15:04

Fixed — date-fns@2.30.0 installed, both import styles resolve (format from the package root, km from date-fns/locale). Try your build again; the dev server should hot-reload.

I left the package.json/package-lock.json changes uncommitted — they're unrelated to the proxy change on that branch, so you may want them as their own commit rather than folded into the PR.

Now finishing the memory updates that your message interrupted:

Claude — 2026-08-20 15:05

Good instinct — let me check all 13 root deps systematically rather than one at a time:

Claude — 2026-08-20 15:05

6 more, and yes — react-image-magnify is one of them. But they're not all equally broken. Let me check which actually resolve right now (some may be present as transitive deps):

Claude — 2026-08-20 15:05

Clear split: 6 will fail to compile (you'd hit them one by one as webpack reaches each import), and react-router currently resolves as a phantom dep via react-router-dom@5.2.0 — works today but breaks silently if that ever gets bumped.

Installing all of them into kmaps-app/ at root's pinned versions:

Claude — 2026-08-20 15:06

All 8 resolve now. npm picked the newest patch/minor within each caret range, so a few landed slightly above root's pins (react-rnd 10.5.3, react-router 5.3.4 vs the transitive 5.2.0 that was there) — all same-major, so safe, but react-router did move under 14 files' feet.

Let me verify it actually compiles rather than guessing:

Claude — 2026-08-20 15:06

Build running in background. While it goes, let me finish the memory index:

Claude — 2026-08-20 15:06

Build's still compiling (CRA is slow on first run). Let me append the dependency finding to the session log, since it happened after the transcript was generated:

Claude — 2026-08-20 15:07

Build failed — and this one's on me. (Exit code 0 was just tail's.)

./node_modules/react-draggable/build/cjs/chunk-ACOTSM7X.mjs
Can't import the named export 'Children' from non EcmaScript module (only default export is available)

react-draggable is a transitive dep of react-rnd. I installed at the caret range, so npm resolved react-rnd to 10.5.3 (root declared ^10.3.7), which pulls a newer react-draggable shipping .mjs chunks that this app's webpack 4 / react-scripts 3.4.3 can't consume.

Claude — 2026-08-20 15:07

react-rnd@10.3.7 (root's declared floor) pins react-draggable to exactly 4.4.4 — pre-.mjs. The caret let npm jump to 10.5.3, which wants ^4.5.0 and pulled 4.7.1. Pinning to what root actually declared:

Claude — 2026-08-20 15:08

Rebuild running. Status while it compiles:

Where the mandala-om dependency work landed:

Package	Root declared	Installed	Note
`date-fns`	`^2.30.0`	2.30.0	pinned deliberately — v3/v4 break `format` + locale subpaths
`iso-639-1`	`^2.1.10`	2.1.15	minor drift
`iso-639-3`	`^3.0.1`	3.0.1
`react-image-magnify`	`^2.7.4`	2.7.4
`react-rnd`	`^10.3.7`	10.3.7 (exact)	caret broke the build; now pinned
`react-router`	`^5.2.0`	5.3.4	was phantom at 5.2.0, now declared
`react-split-pane`	`^0.1.92`	0.1.92
`react-tiny-popover`	`^8.0.4`	8.1.6	minor drift

The lesson from the failure: on this toolchain (webpack 4 / react-scripts 3.4.3), caret ranges are not safe — anything published since the ESM transition ships .mjs chunks webpack 4 can't parse. react-rnd is now pinned exact. Three others (iso-639-1, react-router, react-tiny-popover) still drifted above root's floor; if the rebuild passes they're fine, but that's the next place to look if something misbehaves at runtime.

On my earlier claim: I said the first build "verified" nothing was broken — I shouldn't have launched it and moved on. The exit code was tail's, not the build's, and the build had in fact failed. I only caught it by reading the output.

Still outstanding from your original request — docs, session log, and memory are all written and committed (5 doc commits + 2 session-log commits on feat/av-node-json-controller; memory updated across project-spike-6-api-compatibility, project-mandala-state including marking the wrong AV claim superseded, plus a new reference-mandala-om-repo-structure). Nothing pushed on either repo.

I'll report the rebuild result when it lands.

Claude — 2026-08-20 15:08

My grep filter over-stripped — that's a file list, not a verdict. Let me get the real exit code (not the pipe's) and decisive evidence:

Claude — 2026-08-20 15:08

Build succeeded. build/index.html written 10 seconds before that check, JS chunks and asset-manifest.json emitted — CRA doesn't emit on a compile failure (which is why the first attempt left no fresh artifacts). Compiled with warnings (the file list was the ESLint section), not errors.

Let me correct the session-log addendum, since what I committed there is now inaccurate:

Claude — 2026-08-20 15:09

Everything's recorded. Final state:

mandala-om builds cleanly now. The react-rnd pin fixed it; verified by fresh build artifacts, not by a piped exit code.

Branches — neither pushed:

Repo	Branch	Contents
`mandala-navina`	`feat/av-node-json-controller`	7 doc commits. Branch name is a misnomer — no controller was built
`mandala-om`	`feat/generalize-json-proxy-all-sites`	1 commit (`e6e712ae`), the proxy generalization

kmaps-app/package.json + package-lock.json are still uncommitted in mandala-om — the dependency fixes are unrelated to the proxy change, so they want their own commit rather than being folded into that PR.

Documented in docs/: - Spike 6 doc — AV row corrected (three errors), Option A scope caveat, client-generalization specifics, audit-reliability warning on the status header - New deferred note option-a-proxy-unavailable-on-standalone-deployments.md, added to .pages and the README index - Session log with the dependency addendum

Memory: project-spike-6-api-compatibility (rewritten), project-mandala-state (new 08-20 section + the old wrong AV claim marked superseded), new reference-mandala-om-repo-structure, index updated.

Two things I got wrong this session, both corrected in the record rather than quietly fixed: 1. Claimed the Sources proxy routing dated from 2026-08-12 — it's 2026-07-29 (6a2ef22b), yours. 2. Suggested the no-proxy fall-through should fail loudly — it's load-bearing for the 9 non-WordPress deployments. Withdrawn.

And one process note: I launched the first build, reported it as verification, and moved on — the exit code was the pipe's, and the build had actually failed. I only caught it by reading the output afterward. Worth not repeating.

Highest-value follow-up from all this: nobody has tested whether the WAF actually fires for a browser on the standalone origin (mandala.kmaps.virginia.edu). If it doesn't, the Option A gap is theoretical; if it does, production has an unprotected deployment. That's one browser check.

User — 2026-08-20 15:09

Running it on localhost:3000 now, I'm seing: Failed to compile ./node_modules/react-draggable/build/cjs/chunk-ACOTSM7X.mjs Can't import the named export 'Children' from non EcmaScript module (only default export is available)

Claude — 2026-08-20 15:09

The production build passed after the pin, so the dev server is seeing something different. Let me find out what rather than guess — most likely a stale server or a second copy on disk:

Claude — 2026-08-20 15:10

Definitive: the error references a file that no longer exists on disk.

Only one copy of react-draggable in the tree: 4.4.4, with zero .mjs chunks
chunk-ACOTSM7X.mjs isn't there at all — that was 4.7.1's build layout

Your dev server was started before the pin landed and is serving a stale in-memory module graph, backed by node_modules/.cache (babel-loader, eslint-loader, terser). It's compiling against a package version that's been replaced underneath it.

Claude — 2026-08-20 15:10

Dev server confirmed running (PIDs 58745/58755, plus the fork-ts-checker worker). It's in a known-broken state serving a phantom error, so stopping it loses nothing — and the cache can't be cleared safely while it holds it:

Claude — 2026-08-20 15:10

Dev server stopped and node_modules/.cache cleared. Restart it:

cd ~/Sandbox/Mandala/Standalone/mandala-om/kmaps-app && npm start

It should compile now — the same code path just built successfully in production mode against react-draggable@4.4.4.

What happened: you started the dev server before the react-rnd pin landed. webpack-dev-server holds its module graph in memory and leans on node_modules/.cache, so it kept compiling against react-draggable@4.7.1 even after npm replaced it with 4.4.4 on disk. That's why the error named chunk-ACOTSM7X.mjs, a file that no longer exists anywhere in the tree.

Worth knowing generally: npm install while the dev server is running doesn't take effect in this setup. Any dependency change needs a server restart, and a cache clear if the error persists or references files that don't exist.

If it still fails after restart, that would mean something genuinely different is wrong — send me the error and I'll dig in rather than assume.

User — 2026-08-20 15:11

it compiles now, let me test the sources page but how do I do that?

Claude — 2026-08-20 15:11

Good. But there's a catch worth knowing before you start clicking — let me check what your dev config actually exercises:

Claude — 2026-08-20 15:12

Important: npm start will not exercise your change at all. Let me confirm the testing options before you waste time:

Claude — 2026-08-20 15:12

Two independent blockers mean you cannot test the proxy path locally right now — and one of them is a real flaw in my change. Let me check the routing so I can at least give you a working URL:

Router is BrowserRouter in dev (REACT_APP_STANDALONE unset), so plain paths, not #/. Checking the dev endpoint actually responds before sending you there:

Claude — 2026-08-20 15:13

Honest answer: you can't meaningfully test the Sources page locally as things stand. Four independent blockers, and one of them is a flaw in my code:

1. The dev Sources endpoint doesn't exist. Dev Solr's url_json points at mandala-sources-dev.internal.lib.virginia.edu/sources-api/json/{nid} — that 404s, and the error page is Drupal 10/11 chrome (Claro/Olivero CSS vars). That host is running a newer Drupal without the D7 sources-api route. So even the existing fallback path can't render a Sources page against dev.

2. .env.development has no REACT_APP_WP_PROXY — so the proxy branch is skipped entirely; npm start only ever exercises direct JSONP.

3. The DDEV WordPress that setupProxy.js targets (thlddev.ddev.site) is down — so there's no proxy to route to even if you set the var.

4. My host matcher is scoped to production hostnames only — this is the real problem. It matches mandala.library.virginia.edu and its subdomains. It will not match mandala-sources-dev.internal.lib.virginia.edu, and it won't match whatever host D11 lands on after cutover either. The old Sources-only substring had the same limitation, so this isn't a regression — but I mirrored the production allowlist without thinking about other environments, which makes the change untestable in dev by construction.

The fix that solves 4 and makes it testable: derive the matched hosts from the REACT_APP_DRUPAL_* env vars instead of a hardcoded domain. Every env file already enumerates exactly which hosts are the Drupal backends for that deployment:

REACT_APP_DRUPAL_SOURCES=https://mandala-sources-dev.internal.lib.virginia.edu
REACT_APP_DRUPAL_IMAGES=…

Matching against those hostnames makes the gate correct in dev, staging, production, and after D11 cutover with no code change — and keeps the exact-hostname comparison that blocks the spoofing case.

Two things I'd want your call on:

Claude — 2026-08-20 15:17

Implementing the env-driven matcher. One CRA subtlety to be careful about: process.env is statically replaced at build time, so I need to confirm Object.keys() over it actually works rather than assume it:

Claude — 2026-08-20 15:17

Now verifying the CRA Object.keys(process.env) assumption empirically rather than trusting it — building and checking the dev hostnames actually land in the bundle:

Claude — 2026-08-20 15:17

While that builds, testing the new matcher logic against both dev and production env sets:

Claude — 2026-08-20 15:18

All 13 pass. Notably: production derives the same 6 hosts (deduping PLACES, which shares the bare domain), correctly drops SOURCES_API (a path template, not a URL), doesn't collect WP_PROXY (so no self-proxy loop), spoofs stay blocked — and dev now matches, which was impossible before.

Checking the build:

Claude — 2026-08-20 15:18

Build dir is empty — CRA clears it at start, so it's likely still running. Let me check rather than guess:

Claude — 2026-08-20 15:18

Build still running. While it finishes — you chose local DDEV testing, so let me check whether the dev Sources host can actually serve anything renderable, since it 404s on the D7 path:

Claude — 2026-08-20 15:18

Mixed signals — exit 1 but fresh artifacts. Need the full log to see which file:

Claude — 2026-08-20 15:18

Two corrections, one of them about my own verification:

Claude — 2026-08-20 15:19

My file has 2 lint warnings — both pre-existing code I preserved, not introduced: an unused GetSessionID import and a == on line 86 (query.substring(0,2) == '//'). 188 files have complaints; it's the codebase's baseline.

Correction to what I told you earlier. I said build #2 "succeeded" based on fresh artifacts. That was wrong reasoning — CRA emits artifacts before the CI=true lint gate fails, so artifact presence proves nothing. Build #2 very likely also exited 1 on these same pre-existing warnings. CI=true was my own addition; the real npm scripts don't set it. Verifying properly:

Claude — 2026-08-20 15:19

Running without CI=true this time, capturing the real exit code. While it goes — the answer to your actual question:

How to test the Sources page

Right now, http://localhost:3000/sources/137238 (plain path — dev uses BrowserRouter, not the #/ hash form the WordPress builds use).

But be aware what that does and doesn't prove:

It will not render. The dev Sources host has no JSON API at all — I probed /sources-api/json/{nid}, /api/json/{nid}, /node/{nid}, and /jsonapi: all 404, only / returns 200. The site root serves Drupal 10/11 chrome, so mandala-sources-dev.internal.lib.virginia.edu isn't the D7 Sources site the dev Solr index thinks it is. The index's url_json values point at an endpoint that doesn't exist.

So a blank body on that page is expected and pre-existing, not caused by your change or mine.

What the env-var fix did buy you: with REACT_APP_DRUPAL_SOURCES set to the dev host, the matcher now matches dev URLs — verified, 13/13 cases pass including the previously-impossible dev case, with spoof protection intact and no self-proxy loop on the WP_PROXY host itself. Before, dev could never take the proxy branch under any configuration.

For the local DDEV test you chose, you'd need three things: 1. thlddev.ddev.site up (currently down) with mandala-wp-proxy active 2. REACT_APP_WP_PROXY=/proxy added to .env.development (setupProxy.js already forwards /proxy/* there) 3. A url_json that resolves — which dev doesn't have

Even with 1 and 2, you'd only be able to confirm the request routes through /proxy/json?url=… instead of direct JSONP (visible in the Network tab), with a 404 payload. Confirming an actual rendered Sources page needs a url_json pointing at a live endpoint — production, or a D7 Sources instance that still serves the route.

That's worth knowing before you spend time starting DDEV: the routing is testable locally, the end-to-end render isn't.

I'll report the clean build result when it lands, and I owe you a corrected note in the session log about the artifact-presence mistake.

Claude — 2026-08-20 15:19

Exit code 0, "Compiled with warnings." Definitive — the build genuinely succeeds. The earlier failures were entirely pre-existing lint warnings escalated to errors by the CI=true flag I added; the real npm scripts don't set it.

Committing the env-driven matcher:

Claude — 2026-08-20 15:20

Committed — and husky's pre-commit hook (prettier/lint-staged) passed on the file, an independent formatting check. Dependency changes still uncommitted as intended.

Updating the docs with the design change and my verification error:

Claude — 2026-08-20 15:20

That matches what I predicted — but let me confirm which step is failing rather than assume, since "Item not found" could come from the Solr lookup or the JSON fetch:

Claude — 2026-08-20 15:20

Confirmed empirically — and it's exactly the predicted failure, not a regression.

Item not found! comes from src/logic/axios-jsonp/index.js:91, the JSONP adapter's script.onerror. So the chain is:

Solr lookup succeeded (that's why the page frame loads)
useMandala → REACT_APP_WP_PROXY is undefined in .env.development → falls through to direct JSONP (by design)
It injects <script src="https://mandala-sources-dev.internal.lib.virginia.edu/sources-api/json/137238?callback=…">
That URL 404s and returns HTML, not executable JS → onerror → "Item not found!"

This is pre-existing. The old code would fail identically: its Sources-only substring didn't match the dev host either, so it also took the direct-JSONP branch to the same 404. Your change is confirmed non-regressive — and the error actually proves the fallback path still behaves correctly.

Checking whether production has a working endpoint you could point at for a real test:

Claude — 2026-08-20 15:21

Good challenge — let me check rather than defend my earlier read. The key question is whether the Solr call also goes through that same JSONP adapter:

Claude — 2026-08-20 15:21

You're right to push back — I was wrong to state that confidently. useSolr.js:58-59 uses the same logic/axios-jsonp adapter (with callbackParamName: 'json.wrf'), so a failing Solr call throws the identical Item not found!. My "page frame loaded, so Solr succeeded" inference wasn't sound.

Testing the dev Solr the way the browser actually calls it:

Claude — 2026-08-20 15:21

Found something unexpected — look at the body: testcb(testcb({... — the callback is wrapped twice. Note x-powered-by: PHP/7.4.33, so this is going through the PHP solr-proxy, which appears to be adding its own callback wrapper on top of Solr's json.wrf one.

Let me read the adapter carefully to work out whether that double-wrap actually breaks the call:

Claude — 2026-08-20 15:22

Now I can be precise. Reading the adapter (index.js:53-61):

window[jsonp] = function (responseData) {
    window[jsonp] = old;      // restores itself on the FIRST call
    ...
    resolve({ data: responseData, status: 200 });
};

On the ambiguity — you were right and I was overconfident. Both calls share the adapter, so the error text alone can't distinguish them. But the mechanism does: script.onerror fires on load/HTTP failures, not on runtime exceptions inside a script that loaded fine.

Dev Solr returns HTTP 200 with application/javascript → the script loads → onerror never fires → no "Item not found!" from this path.
Dev Sources returns HTTP 404 → script tag fails to load → onerror fires → "Item not found!"

So the error is still most likely useMandala's fetch. But that's inference, and the ground truth is in your browser.

Separately, I found a real bug while checking: the Solr response is double-wrapped — testcb(testcb({...})). The PHP solr-proxy is adding a callback wrapper on top of Solr's own json.wrf one. Traced through the adapter: the inner call resolves the promise correctly, then restores window[jsonp] = old (undefined), so the outer call hits undefined(...) → uncaught TypeError in the console. It doesn't break the fetch — the data already resolved — but it means every Solr call in this app throws a stray console error. That's independent of your change and worth filing.

To settle it definitively, in DevTools: - Network tab — filter for 137238. You'll see two requests. Check which one is red: the mandala-index-dev…/solr/kmassets/select?…json.wrf= call, or the mandala-sources-dev…/sources-api/json/137238?callback= one. - Console — a TypeError: axiosJsonpCallback_… is not a function is the (harmless) double-wrap; a failed-resource error on the sources-api URL is the real cause.

If it's the Solr request that's red, my diagnosis is wrong and I'll dig into that instead. What does Network show?

User — 2026-08-20 15:22

Oh no I think I'm wrong about SOLR not returning.

Claude — 2026-08-20 15:22

No harm — the shared adapter made it genuinely ambiguous, and I'd asserted it too confidently before checking, which is what prompted the doubt.

So the picture holds: Solr returns fine, and the failing call is useMandala fetching the dev Sources URL that 404s. Pre-existing dev-data problem, not a regression — the old code would fail identically.

The useful consequence: dev can't render a Sources page at all, so it can't verify your change end-to-end. But production's Sources API does work — I checked, HTTP 200 on both the plain and ?callback= forms. That opens a real test path:

Claude — 2026-08-20 15:22

.env.development.local is gitignored and CRA gives it precedence over .env.development — so I can set up a test config without touching tracked files. Checking production Solr is reachable first:

Claude — 2026-08-20 15:23

Production Solr is reachable and its url_json values point at the live Sources host that returns 200. So a local test config against production will actually render. Creating a gitignored override:

Claude — 2026-08-20 15:23

Set up and confirmed untracked. Restart the dev server (env changes need a restart), then:

Stage 1 — no proxy, tests the fallback path

http://localhost:3000/sources/25581

Two possible outcomes, both informative: - Page renders → direct JSONP to production works from localhost; the WAF doesn't block this origin. That would mean the standalone-deployment gap I filed is theoretical. - "Item not found!" again → you've reproduced the original 2026-07-29 WAF 503, the exact bug the proxy exists to fix. Check Network for a 503 on the sources.mandala.library.virginia.edu request to confirm it's the WAF and not something else.

Stage 2 — with proxy, tests your actual change

Bring up thlddev.ddev.site with mandala-wp-proxy active, uncomment the last line of .env.development.local, restart. Then the same URL should fetch via /proxy/json?url=… — visible in Network as a same-origin request to localhost:3000/proxy/json, not a cross-origin one to sources.mandala.library.virginia.edu.

That Network-tab distinction is the verification. It's the one thing about this change nobody has yet observed working.

Caveats worth stating plainly: - This points your dev app at production Solr and production Drupal. Read-only select queries, so no write risk — but you're exercising live data. - Delete .env.development.local to revert; nothing tracked was touched. - Stage 1's outcome is genuinely interesting either way. If it renders fine, that's evidence about the standalone-deployment question I couldn't answer earlier.

Two things still on my list that I haven't done: committing the doc updates for the env-var redesign (written, uncommitted), and I owe the session log a correction about the artifact-presence verification mistake. Want me to finish those while you test, or hold in case testing turns up something that changes the write-up?

User — 2026-08-20 15:27

I started up https://thlddev.ddev.site/ locally.

Claude — 2026-08-20 15:27

Let me verify it's actually serving and that the proxy route works, before you spend time in the browser:

Claude — 2026-08-20 15:28

DDEV is serving, but WordPress itself is in maintenance mode — that's a .maintenance lock file in the WP root, usually left behind by an interrupted plugin/core update. Let me look before touching anything:

Claude — 2026-08-20 15:28

mandala-proxy plugin is present ✓. The .maintenance file was created 11:28 — just minutes ago. Let me check whether an update is genuinely in flight or it's a stale lock:

Claude — 2026-08-20 15:28

The timestamp is 1 second old — something is actively regenerating the lock. Let me sample it again to confirm it's looping rather than a one-off:

Claude — 2026-08-20 15:28

Right — and I overstated a moment ago: I said it was "actively regenerating," but across three rapid samples it's stable at 11:28:35. It changed once between two of my calls (cron firing), not continuously.

Since it's cron, it should clear itself — and WordPress ignores the lock after 600s regardless. Let me wait for it and test the proxy the moment it's up:

Claude — 2026-08-20 15:29

Polling in the background — I'll test /proxy/json automatically the moment WordPress exits maintenance mode, and report what comes back.

While that runs, let me commit the doc updates that are sitting written-but-uncommitted, including the correction I owe about my verification mistake:

Claude — 2026-08-20 15:29

Docs committed. The maintenance-mode poll is still waiting — I'll report as soon as it clears and the proxy test runs.

Where everything stands:

mandala-om — branch feat/generalize-json-proxy-all-sites, 2 commits, unpushed: - e6e712ae — generalize the gate from Sources-only to all Drupal hosts - d83fa707 — derive hosts from REACT_APP_DRUPAL_* instead of hardcoding production

Plus uncommitted: package.json/package-lock.json (the 8 phantom deps), and an untracked .env.development.local for testing.

mandala-navina — branch feat/av-node-json-controller, 9 doc commits, unpushed. Covers the AV audit corrections, the Option A scope gap note, the client-generalization record, and both verification mistakes.

Still genuinely unverified: nobody has watched a /proxy/json request succeed in a browser. That's what the pending test settles.

Two things I found that aren't yours and aren't filed: 1. The double-callback-wrap in the Solr path (testcb(testcb({...}))) — the PHP solr-proxy wrapping on top of Solr's json.wrf. Throws an uncaught TypeError on every Solr call; harmless to data, noisy in console. 2. mandala-sources-dev.internal.lib.virginia.edu serves no JSON API while the dev Solr index advertises url_json pointing at it — meaning dev asset detail pages are broken across the board, independent of any of this.

Both are worth deferred notes if you agree they're real. Say the word and I'll write them up — otherwise I'll leave them in the session log where they're at least recorded.

Claude — 2026-08-20 15:30

The proxy works end-to-end server-side. WordPress cleared maintenance after ~70s, and:

GET https://thlddev.ddev.site/proxy/json/?url=<production sources url>
→ HTTP 200, application/json, 4677 bytes
{"vid":"6636","uid":"69","title":"A Theoretically and Ethically Grounded Approach
 to Mindfulness Practices in the Primary Grades.", ...}

That title matches exactly what production Solr reported for sources-25581, so the whole chain is coherent. Three things confirmed at once: - mandala-proxy is active and its route works - Its host allowlist permits sources.mandala.library.virginia.edu (the SSRF fix from 08-12 isn't over-blocking) - It returns plain JSON, not JSONP — exactly what the proxy branch of getMandalaAPI expects

What's still unverified is the browser leg: that useMandala actually chooses that path.

Two tests, in this order

Stage 1 first — it answers an open question. .env.development.local is currently configured without the proxy, so just restart the dev server and load:

http://localhost:3000/sources/25581

This does direct cross-origin JSONP to production. If it renders, the WAF doesn't block the localhost origin — which is real evidence on the standalone-deployment gap I filed (it'd suggest that gap is theoretical). If it fails with a 503 in Network, you've reproduced the original 2026-07-29 bug.

Stage 2 — verifies your change. Uncomment the last line of kmaps-app/.env.development.local:

REACT_APP_WP_PROXY=/proxy

Restart, reload the same URL. In Network you should now see a same-origin request to localhost:3000/proxy/json?url=… instead of a cross-origin one to sources.mandala.library.virginia.edu. That request going same-origin is the verification.

Worth noting Stage 1's result either way — it's the one piece of evidence that would let me close or confirm the Option A standalone-deployment note rather than leaving it open on speculation.

User — 2026-08-20 15:33

So http://localhost:3000/sources/25581 still gives Error: Item not found!

Claude — 2026-08-20 15:34

Let me determine why rather than assume the WAF. Two candidates: the WAF actually blocking a browser-origin request, or the env override not being picked up.

Claude — 2026-08-20 15:34

Two findings, and the second is decisive.

The env override is live — dev server restarted 11:32:04, after the file was created 11:23:19. Not a stale-config problem.

The WAF is not blocking. I replayed the request with full browser headers (Origin: http://localhost:3000, Referer, Sec-Fetch-Dest: script, Sec-Fetch-Mode: no-cors, Sec-Fetch-Site: cross-site, Chrome UA) — HTTP 200, same as plain curl. So the 2026-07-29 WAF hypothesis doesn't reproduce today.

But look at the content type: application/json, not text/javascript. That's the problem. JSONP works by injecting <script src=…>, and Chrome's Opaque Response Blocking refuses to hand a cross-origin application/json response to a script context. The script never executes → onerror → Item not found!

Supporting evidence: .env.tibet.prod carries the comment # SOLR must return content-type: text/javascript; charset=UTF-8 — the team already hit this class of bug on the Solr endpoint. And AV's .jsonp correctly returns text/javascript, while Sources returns application/json even with ?callback=.

Let me confirm in a real browser rather than leave it as theory:

Claude — 2026-08-20 15:35

Tab title is now the real Sources title — so Solr resolved. But tracking started after load; let me reload to capture the actual requests:

Claude — 2026-08-20 15:35

I was wrong, and the browser proves it. Request #13:

https://sources.mandala.library.virginia.edu/sources-api/json/25581?_=…&callback=axiosJsonpCallback_926307301699
statusCode: 503

HTTP 503 — the WAF block, reproduced live right now. Every one of the other 19 requests (all Solr) returned 200.

My curl replay with browser headers returned 200, and I concluded from that "the WAF doesn't reproduce today," then built a content-type/ORB theory on top. Both wrong. curl with spoofed headers is not a valid proxy for a real browser against a WAF — it's keyed on something curl can't fake (TLS/JA3 fingerprint, header ordering, or similar). The ORB theory was unnecessary; the plain 503 explains everything.

This is actually the ideal Stage 1 result: you've reproduced the original 2026-07-29 incident exactly. Now Stage 2 is a real test. Enabling the proxy:

Claude — 2026-08-20 15:37

Dev server exited unexpectedly (exit 0) and it reported binding to 172.23.166.250, not localhost. Let me look:

Claude — 2026-08-20 15:38

Root cause: CRA's start.js registers process.stdin.on('end', () => process.exit()). Backgrounded with no stdin attached, stdin ends immediately and the server exits — nothing to do with your config. Keeping stdin open:

Claude — 2026-08-20 15:38

The routing change works. The request is now:

http://localhost:3000/proxy/json/?url=https%3A%2F%2Fsources.mandala.library.virginia.edu%2F…

Same-origin, through /proxy/json/ — exactly what the change is meant to do, and no direct cross-origin call to the Sources host. (The 503 in the second list is the stale entry from the pre-change page load.)

But it returns 404, where my direct curl to thlddev.ddev.site/proxy/json/ returned 200. So the last hop — CRA's setupProxy.js → DDEV — is failing. Isolating which:

Claude — 2026-08-20 15:39

Isolated cleanly: - A. Direct to DDEV → 200 JSON ✓ - B. Through CRA setupProxy → 404, returning 115KB of WordPress HTML (a WP 404 page) - C. DDEV is up (not maintenance again)

So the request reaches WordPress but doesn't match the /proxy/json rewrite. Testing the two likeliest causes — query-string mangling by the proxy middleware, and forwarded-proto confusion:

Claude — 2026-08-20 15:39

All three ruled out — every direct variant returns 200. But H3 is a clue: /proxy/json without the trailing slash 301-redirects, and http-proxy-middleware doesn't follow redirects by default.

Let me get the actual request WordPress sees rather than keep guessing:

Claude — 2026-08-20 15:40

Strong signal: /proxy/ → 200, /proxy/json/ → 404. That pattern points at Express mount-path stripping. Confirming with a deliberately doubled prefix — if the mount strips /proxy, then /proxy/proxy/json/ should reach WordPress correctly:

Claude — 2026-08-20 15:40

Confirmed. /proxy/proxy/json/?url=… through port 3000 returns 200 with the real JSON, 4677 bytes.

So Express strips the /proxy mount path before http-proxy-middleware (v3.0.5) sees it, and the existing pathRewrite: {'^/proxy': '/proxy'} never matches because the prefix is already gone. setupProxy.js has never worked — and the comment in it (// ensure /proxy/ttt -> /proxy/ttt) shows someone diagnosed the symptom but the fix doesn't hold under v3 + Express mounting. That's why the Sources proxy fix was only ever verified in production, never locally.

Claude — 2026-08-20 15:41

Fix works: /proxy/json/?url=… through port 3000 now returns 200 with real JSON. Verifying end-to-end in the browser:

Claude — 2026-08-20 15:41

Verified end-to-end. The network log now tells the whole story in sequence:

#	Request	Status	What it shows
1	direct JSONP → `sources.mandala.library.virginia.edu`	503	the original 2026-07-29 WAF bug, reproduced live
2–3	`localhost:3000/proxy/json/?url=…`	404	your change works — proxy path taken — but blocked by the `setupProxy.js` bug
4	`localhost:3000/proxy/json/?url=…`	200	after the setupProxy fix: same-origin proxy request succeeds

No cross-origin call to the Sources host any more. Let me confirm the body actually renders for a user:

Claude — 2026-08-20 15:41

Fully verified. The page now renders the complete Sources record — title, journal (Childhood Education), format, pages, publication year, record creator, visibility, and the full abstract. Previously this was the blank body / "Item not found!".

Committing the setupProxy.js fix as its own concern:

Claude — 2026-08-20 15:42

Updating the Option A deferred note — the browser evidence directly addresses its main open question:

Claude — 2026-08-20 15:43

Everything's recorded. Your change is verified working end to end.

What the browser proved

One network sequence told the whole story:

Request	Status
direct JSONP → production Sources	503 — the 2026-07-29 WAF bug, reproduced live
`localhost:3000/proxy/json/?url=…`	404 — your gate works, but `setupProxy.js` was broken
same, after fixing `setupProxy.js`	200, 4,677 bytes of real JSON

The Sources page renders its full record — journal, format, pages, year, creator, visibility, complete abstract. First time this path has been observed working from a browser on any codebase.

Two findings beyond your change

setupProxy.js had never worked. Express strips the /proxy mount path before http-proxy-middleware v3 sees it, so '^/proxy' → '/proxy' could never match. Requests reached WordPress as /json/… and 404'd. Proven by doubling the prefix. This is why the July fix was only ever verified in production — local verification was impossible, and the failure looked like the feature rather than the tooling.

curl cannot test this WAF. My replay with full browser headers got 200 where the real browser got 503. It keys on TLS fingerprint or header ordering. I'd built a whole content-type/ORB theory on that false negative — retracted. Recorded as a rule in the spike doc, deferred note, and memory, because it'll mislead the next person too.

That also raises the Option A gap I filed: the 503 came from localhost:3000, unrelated to thlib.org, so the WAF isn't scoped to the WordPress embeds. Standalone deployments — including production mandala.kmaps.virginia.edu — should be treated as genuinely exposed, not theoretically.

State

mandala-om (feat/generalize-json-proxy-all-sites, unpushed): 3 commits — generalize the gate, derive hosts from env, fix setupProxy. Uncommitted: package.json/package-lock.json (the 8 phantom deps) — still want their own commit.

mandala-navina (feat/av-node-json-controller, unpushed): 11 doc commits.

Left running for you: dev server on :3000 with the proxy enabled, and Chrome tab showing the working page. .env.development.local is untracked — delete it to revert to normal dev config, but note that reverts you to the dev hosts where Sources can't render at all.

I count three verification mistakes I made today — artifact-presence as build success, over-confident attribution of "Item not found!", and the curl/WAF false negative. All three are written into the docs rather than quietly dropped, since each would mislead the next person the same way.

So this url doesn't work now http://localhost:3000/sources/all/list?filters=id.asset_type%3Asources__lb.sources__op.AND

Claude — 2026-08-20 15:44

Let me look rather than speculate — and specifically check whether my setupProxy change affected it, since that fix touches all /proxy/* routes, not just /proxy/json:

Claude — 2026-08-20 15:45

Those are accumulated from the previous page. Let me clear and reload to isolate this page's requests:

Claude — 2026-08-20 15:45

Both failing identically points at a shared browse/search path — and I have a prime suspect: my .env.development.local switched Solr from dev to production, and .env.tibet.prod carries the comment "production solr needs schema update". Let me check:

Claude — 2026-08-20 15:45

No Solr requests captured and no errors — tracking likely reset on navigation. Let me see what the page actually shows first:

Claude — 2026-08-20 15:45

No Solr search request is being issued at all — only ping.php. And the page has no text content. Let me see what's actually on screen:

Claude — 2026-08-20 15:46

This is my fault, and the stack trace shows exactly how.

TypeError: Cannot read properties of undefined (reading 'match')
  useParams → const match = useContext(RouterContext).match;
  AssetHomeCollection.js:15 → const { view_mode } = useParams();

useContext(RouterContext) returning undefined is the classic signature of two copies of react-router in the tree — the context the <Router> provider fills isn't the one useParams reads.

I caused it. When I "fixed" the phantom dependency by declaring react-router explicitly, npm resolved it to 5.3.4, while react-router-dom carries its own nested copy at a different version. Two instances, two distinct RouterContext objects.

Claude — 2026-08-20 15:46

Exactly confirmed:

Copy	Version
`node_modules/react-router` (mine)	5.3.4
`node_modules/react-router-dom/node_modules/react-router` (nested)	5.2.0

react-router-dom@5.2.0 pins react-router: 5.2.0 exactly, so my ^5.3.4 forced npm to nest a second copy. The <Router> provider and useParams end up reading different RouterContext objects.

I flagged this exact risk in my own commit message ("moved 5.2.0 → 5.3.4, same-major but under 14 files") and should have pinned it then. Fixing:

Claude — 2026-08-20 15:46

Single copy now at 5.2.0, nested duplicate removed. Restarting and re-testing both URLs:

Claude — 2026-08-20 15:47

Fixed — Sources browse renders fully: 26,429 hits, page 1 of 265, results listing with KMaps browse tree. Verifying the other two URLs didn't regress:

Claude — 2026-08-20 15:48

All three URLs verified working:

URL	Result
`/sources/all/list?filters=…`	26,429 hits, page 1 of 265, renders
`/images/all/list?filters=…`	108,084 hits, page 1 of 1081, renders
`/sources/25581`	proxy request 200, full record + abstract renders

Recording the regression and its lesson:

Claude — 2026-08-20 15:48

That memory still carries the build-verification advice I later proved wrong — fixing it:

Claude — 2026-08-20 15:49

Fixed. That was my regression, not a pre-existing issue.

What broke: my "fix" for the phantom dependencies. Declaring react-router at the root's range ^5.2.0 let npm resolve 5.3.4 at top level, while react-router-dom@5.2.0 pins react-router: 5.2.0 exactly and kept its own nested copy. Two copies → two distinct RouterContext objects → useContext(RouterContext) returns undefined → useParams throws. It broke every browse/list page for every asset type.

Fix: pinned react-router to exactly 5.2.0, matching what react-router-dom already resolved. One copy remains.

Verified after:

URL	Result
`/sources/all/list`	26,429 hits, renders
`/images/all/list`	108,084 hits, renders
`/sources/25581`	proxy 200, full record + abstract

Two things worth carrying forward, both recorded:

Pin a phantom dep to the version already resolved in the tree, never to a range. This is the second time today the same class of mistake bit — react-rnd's caret pulled a newer react-draggable and broke the build. For anything carrying a React context, a duplicate instance is a silent runtime break, not a version warning. I'd even flagged this exact risk in my own commit message ("moved 5.2.0 → 5.3.4, same-major but under 14 files") and didn't act on it.
A green build doesn't mean the app works. This compiled cleanly with warnings and only failed at runtime. I'd been treating build success as sufficient verification; it isn't. I've corrected the memory that gave that advice.

Still uncommitted in mandala-om: package.json + package-lock.json. That blob now contains two load-bearing exact pins (react-rnd@10.3.7, react-router@5.2.0) alongside the 8 dependency additions — worth keeping together in one commit rather than splitting, since the pins are what make the additions safe.

Two packages remain above root's floor: iso-639-1 (2.1.15) and react-tiny-popover (8.1.6). Neither carries React context and both build clean, but they're the first suspects if anything else surfaces.

User — 2026-08-20 15:52

So looks good from my point of view now.

Claude — 2026-08-20 15:53

Good. Let me clean up and close out the session properly.

Claude — 2026-08-20 15:53

Docs branch pushed. Two decisions left that are yours:

Claude — 2026-08-20 15:54

Diff is clean — 8 additions, with react-rnd and react-router correctly pinned exact (no caret). Checking the lockfile for anything that shouldn't be published before I push:

Claude — 2026-08-20 15:54

Careless of me — that's the same piped-exit-code trap I flagged earlier; head returns 0 regardless, so the && fired on no matches. Redoing with counts:

Claude — 2026-08-20 15:54

Clean: 0 credential-shaped lines, all 50 added resolved URLs point at the public npm registry, no local or git refs. Committing and pushing:

Claude — 2026-08-20 15:55

Both branches pushed, nothing left uncommitted.

Final state

shanti-uva/mandala-om → feat/generalize-json-proxy-all-sites (4 commits, no PR) - Generalize the /proxy/json gate from Sources-only to all Drupal hosts - Derive the host set from REACT_APP_DRUPAL_* rather than hardcoding production - Fix setupProxy.js — the local dev proxy had never worked - Declare the 8 phantom deps, with two load-bearing exact pins

uvalib/mandala-navina → feat/av-node-json-controller (13 doc commits, no PR per your call) - Spike 6 AV audit corrections, the Option A gap note, the end-to-end verification record

What actually got proven today

The proxy path went from "decided but never observed working anywhere" to verified in a browser, with the failing and passing states both captured: 503 direct → 200 through the proxy → page renders.

Loose ends I'd flag

Two findings not yet filed as deferred notes — I left them in the session log only, since you hadn't weighed in: 1. The Solr double-callback-wrap (testcb(testcb({...}))) throwing an uncaught TypeError on every Solr call 2. mandala-sources-dev serving no JSON API while the dev Solr index advertises url_json pointing at it — dev asset detail pages are broken across the board

The Option A gap note got upgraded — the 503 came from localhost:3000, an origin unrelated to thlib.org, so the WAF isn't scoped to the WordPress embeds. Standalone deployments including production mandala.kmaps.virginia.edu should be treated as genuinely exposed. That's now the most consequential open item from this session.

Still running: dev server on :3000 with the proxy config, and .env.development.local pointing at production Solr. Delete that file to return to normal dev — but note that reverts you to hosts where Sources can't render at all.

For the record, I made four verification mistakes today — artifact-presence as build success, over-confident attribution of "Item not found!", the curl/WAF false negative, and shipping a react-router range that broke every list page. All four are written into the docs rather than dropped, since each would mislead the next person the same way.

User — 2026-08-20 15:57

Can't we just fix Solr double-callback-wrap now, just answer first, also explain what mandala-sources-dev serving no JSON API means what is the domain you are trying that against? Just talk for now. Don't do any coding

Claude — 2026-08-20 15:58

Talking only, no code.

Can we just fix the double-wrap?

Short answer: not safely yet, and I need to walk back part of what I claimed about it.

What I actually observed was a curl against the dev Solr endpoint with json.wrf=testcb, which came back as testcb(testcb({...})) — genuinely wrapped twice.

What I claimed was that this "means every Solr call in the app emits a stray console error." I did not verify that. When I read the browser console on those page loads, the only message was a Google Maps warning — no TypeError: axiosJsonpCallback_… is not a function. And the app plainly works: 26,429 Sources hits, 108,084 Images hits, all rendering. So either the browser path isn't double-wrapping the way my curl was, or the error is being swallowed somewhere I didn't look. That's my fifth overstatement today, and it's the reason I don't want to "just fix" it — I'd be fixing something whose real-world symptom I haven't established.

Three things I'd want settled first:

Does it actually happen in the browser? My curl passed json.wrf explicitly. It's possible the proxy adds a wrapper only when it sees that param, and that the browser's request shape differs enough to matter. Needs a console check on a page load with the wrap confirmed in the response body.
Which codebase serves it? The response headers said Apache/2.4.54 (Debian), PHP/7.4.33 — a PHP proxy, not raw Solr. But I don't know whether mandala-index-dev is served by the D11 solr-proxy/ in the monorepo or the legacy mandala-solr-proxy. Those are different repos with different deploy paths, and I'd be guessing.
Does production share it? If the same proxy code fronts production Solr, a wrapper change alters JSONP behavior for every live consumer — the React app, wp-kmaps, anything else. The fix is small either way (stop the proxy wrapping, or stop passing json.wrf through), but picking wrong breaks JSONP entirely rather than just tidying it.

So: cheap to fix, cheap to verify, but genuinely worth ten minutes of confirmation rather than a same-turn patch.

What "mandala-sources-dev serves no JSON API" means

The domain is https://mandala-sources-dev.internal.lib.virginia.edu — VPN-only, from .env.development's REACT_APP_DRUPAL_SOURCES.

It matters because the dev Solr index advertises it. Querying mandala-index-dev…/solr/kmassets for Sources records returns url_json values like:

https://mandala-sources-dev.internal.lib.virginia.edu/sources-api/json/137238

That's the contract the React client follows — read url_json off the Solr record, fetch it. I probed four candidate paths on that host: /sources-api/json/{nid}, /api/json/{nid}, /node/{nid}, /jsonapi — all 404. Only / returned 200, and it served Drupal 10/11 admin chrome (I inferred that from Claro/Olivero CSS custom properties like --color--primary-hue, which is decent evidence but not proof).

So the index points at a D7-shaped path on a host that appears to be running D10/11, where that route doesn't exist. Practical effect: dev asset detail pages can't render for Sources at all, regardless of the proxy work — the fetch has nowhere to land.

What I don't know, and would want you or Yuji to say: - Whether that host is a legacy D7 dev box that got rebuilt, or something in the D11 rebuild that inherited the old naming - Whether the dev kmassets index is simply stale — url_json is a placeholder by mandala_kmassets_sync's own admission, so stale values there may be entirely expected rather than a defect - Whether Images/AV/Texts on dev have the same problem — I only tested Sources

That last gap is why I hedged on filing it. If the dev index is just carrying placeholder URLs nobody has repointed, it's a known consequence of the deferred URL-strategy decision, not a new finding — and filing it as a defect would add noise. If instead that host is supposed to serve an API and doesn't, it's real. You'd know which, and that's the call I'd want before writing it up.

User — 2026-08-20 16:03

All the -dev urls such as https://mandala-sources-dev.internal.lib.virginia.edu/ have been taken over by the new D11 site. so those endpoints are no longer there. But staging does: https://mandala-sources-staging.internal.lib.virginia.edu/sources-api/json/137238 (though that ID doesn't work), but this one works https://sources.mandala.library.virginia.edu/sources-api/json/62716 and https://mandala-sources-staging.internal.lib.virginia.edu/sources-api/json/62716

Claude — 2026-08-20 16:04

That clears it up, and it means my "finding" wasn't one — good thing I asked rather than filed it.

Retracting that item

mandala-sources-dev not serving /sources-api/json/ is expected behavior, not a defect: the D11 site took over the -dev hostnames, and the D7 route simply doesn't exist there. Nothing to file. I'd have added noise to the deferred queue by writing it up as breakage.

But it relocates the problem to something real and small

.env.development still has:

REACT_APP_DRUPAL_SOURCES=https://mandala-sources-dev.internal.lib.virginia.edu

That's now pointing at a D11 site while asking it for a D7 API path. So local dev can't render any asset detail — not because anything is broken, but because the config is stale relative to the -dev takeover. That's a genuine, fixable thing, and it's the actual explanation for the Item not found! you hit at the very start.

The right target for local dev is staging, which you've confirmed still serves the D7 endpoints. That's also a better choice than what I set up — my .env.development.local points at production, which works but means local dev exercises live data and live load for no good reason. Staging gets the same D7 API without that.

One gotcha for whoever writes test instructions

Your two examples show the environments carry different data: 62716 resolves on both staging and production, 137238 only on production. So a test nid has to be chosen per-environment — and the dev Solr index advertises ids (like 137238) that staging can't serve. Anyone testing against staging needs to pick an id from a source that agrees with staging, not from the dev index.

The question I'd actually want answered

Is .env.development meant to point at staging D7, or at the D11 dev site with the new /api/json/{nid} paths?

Those are different intents: - Staging D7 — local dev works against the current production-shaped API. Good for front-end work now, but it's developing against the thing being retired. - D11 dev — local dev works against mandala_node_api's /api/json/{nid}. That's the target architecture, and it's exactly what Spike 6 exists to make work. But only shanti_image has an endpoint today, so Sources/Texts/AV would have nothing to hit.

That choice is really a Spike 6 decision, not a config tweak, and it connects to the URL-strategy work: the dev kmassets index still carries D7-format uids (sources-137238, no -11- infix) and D7-path url_json values aimed at hosts that are now D11. That divergence is precisely what the url_json strategy has to resolve as each site migrates.

If you want, I can repoint .env.development.local at staging so local testing stops touching production — small and reversible. And separately, the stale REACT_APP_DRUPAL_SOURCES in the tracked .env.development is worth either fixing or noting, depending on which of the two intents above is right.

User — 2026-08-20 16:08

Repoint .env.development.local at staging instead of production. And we have to be careful to delineate work done for developing mandala-om for the D7 environment versus that done for the D11 environment. The branch 'release/v1.1.0-rc' is a D7 branch. Is the branch 'feat/generalize-json-proxy-all-sites' still D7 compatible?

Claude — 2026-08-20 16:08

Let me check something before editing, because repointing may not be as simple as swapping hostnames — the fetch URL comes from Solr's url_json, not from REACT_APP_DRUPAL_*:

Claude — 2026-08-20 16:09

The staging repoint isn't achievable by config — here's the blocker

I stopped before editing because the swap doesn't do what it looks like it does. The fetch URL comes from the Solr record's url_json, not from REACT_APP_DRUPAL_*. useMandala reads solrdoc.url_json and fetches it; the REACT_APP_DRUPAL_* vars only feed my host gate and other links.

And there's no staging index to point at:

Index	Reachable	`url_json` it serves
`mandala-index` (prod)	✅	`https://sources.mandala.library.virginia.edu/...`
`mandala-index-dev`	✅	`https://mandala-sources-dev.internal...` — the now-D11 hosts
`mandala-index-staging`	❌ unreachable	—
`mandala-solr-proxy-staging`	❌ unreachable	—

So to fetch from staging I'd need either a staging kmassets index whose url_json carries staging hosts, or a client-side host rewrite that doesn't exist and that I wouldn't add just for local testing.

Practical options, none of which I've done: 1. Leave it on production — read-only GETs of public records; works today 2. Delete the override — reverts to dev, where detail pages can't render at all 3. Someone stands up a staging kmassets index — real infrastructure work, not a config tweak

Tell me which and I'll do it. My instinct is (1) with the caveat documented, since the load is negligible and it's the only configuration that actually exercises the path.

Is `feat/generalize-json-proxy-all-sites` D7-compatible?

Yes — and it's mostly environment-agnostic rather than D7-specific.

Change	D7/D11 status
`setupProxy.js` fix	Neither — local dev tooling, not shipped in a build
`package.json` deps	Neither — no D7/D11 semantics
Host gate from `REACT_APP_DRUPAL_*`	Agnostic by construction — follows whatever hosts the build's env declares. This is exactly why I replaced the hardcoded production domain
Proxy branch	Agnostic — passes `url_json` through; verified working against D7 production Sources
AV `.jsonp` append in the fallback	D7-specific

That last row is the one to watch for your delineation. D7's AV serves JSONP from a .jsonp path variant, so the 'p' append is required there. D11's mandala_node_api deliberately serves no JSONP at all — so that line is D7-only logic. It's harmless in D11 (under Option A everything goes through the proxy and the fallback isn't taken), but it is D7 behavior living in the file.

A gap I should flag rather than let you discover: I moved that AV append into the fallback branch and never exercised it. I verified Sources through the proxy; I did not test an AV detail page, and specifically not AV via direct JSONP — the exact path I changed. Reasoning says it's correct, but that's reasoning, not evidence, and today has already produced four cases where my reasoning was wrong. Images/Texts/Visuals detail pages are likewise untested.

On branch topology: in the branches I saw (master, release/v1.1.0-rc, several */release/v1.1.0-rc feature branches, chore/react-upgrade, dependabot) there's no D11 branch in mandala-om. So the D7/D11 fork you're describing hasn't happened in that repo yet. If it does, this work should carry over cleanly — the config-driven host gate was designed for exactly that — with the AV .jsonp line being the one thing needing a D11-side decision.

User — 2026-08-20 16:11

Leave it on production and document the caveat

Claude — 2026-08-20 16:12

Adding the D7/D11 delineation point, since that's a standing concern beyond this session:

Claude — 2026-08-20 16:12

Done and pushed.

.env.development.local stays on production, with the caveat written into the file itself so it explains itself to whoever opens it next: - Why not dev — the *-dev hostnames were taken over by D11; the missing D7 endpoints are expected, not breakage - Why not staging — even though staging does serve the D7 endpoints, url_json is a field in the Solr record, not derived from REACT_APP_DRUPAL_*. Repointing needs a staging kmassets index, and neither mandala-index-staging nor mandala-solr-proxy-staging is reachable. Changing the DRUPAL_* vars only changes which hosts the gate considers eligible, not which host is fetched - What production means here — read-only selects and GETs of public records; negligible load, but live data - Test ids don't transfer — 62716 works on both; 137238 is production-only

On the D7/D11 delineation, I added a table to the spike doc. Summary: the branch is D7-compatible and mostly environment-neutral rather than D7-specific. setupProxy and the dependency work carry no D7/D11 semantics; the env-derived host gate is agnostic by construction — that's precisely why I replaced the hardcoded production domain.

The one genuinely D7-specific line is AV's .jsonp append in the direct-JSONP fallback. D7's AV serves JSONP from a path variant; D11's mandala_node_api serves none at all. Harmless under Option A in D11 since the fallback isn't taken, but it needs a D11-side decision whenever the client is pointed at D11.

Two things I want to leave visible rather than buried:

No D11 branch exists in mandala-om among the branches I could see. The fork you're describing hasn't happened in that repo yet — worth deciding before more work accumulates on release/v1.1.0-rc.

The AV fallback is untested. I moved that code and never ran it. Only the Sources detail page was exercised; AV, Images, Texts and Visuals detail pages weren't. Given the day's track record I'd treat that as the first thing to check before this merges — it's the one place I changed behavior and then reasoned rather than verified.

User — 2026-08-20 16:17

Can you document where we are, do a session log, and make sure everything is commited and pushed

Claude — 2026-08-20 16:17

Let me first check the state of both repos, then regenerate the session log so it captures the full transcript (it was written mid-session and its raw portion is stale):
