Session Log: Sprint 01 1A7 Image Migration

Date: 2026-06-23
Participants: Xiaoming Wang, Claude Opus 4.8
Outcome: Sprint 1 task 1a.7 ✅ — the pattern-setting D7→D11 image migration, run end-to-end against the full production dump (111,340 images, 0 failures). New mandala_migrations source plugins (D7ImageSatellite per-reference fan-out + orphan skip; D7ShantiImage sidecar/IIIF join + paragraph lookup keys) and four migrations transform the satellite graph into owned paragraphs. Four data-model decisions landed as committed config (carrier fields field_description_title + field_external_class_label; "Unknown" agent default; field_iiif_id + field_image_agents optional). Key finding fixed: D7 KMaps raw is angle-bracket ancestors, not the D11 pipe composite — rebuilt via concat (deferred); node-level KMaps reconcile exactly to baseline, Tibetan/NFC fidelity preserved. Also: field_summary widened 255→1024 (deferred); field_image binaries deferred (note). Full prod run remains a staging activity (1a.9). Note: local Drupal was a vanilla install — reconciled to main (composer install + rebuild) before the work.

This is the raw conversation transcript. Tool calls and code output are omitted; only the text exchanges are recorded.

can you summarize current status of the project

Claude — 2026-06-23 14:52

I'll orient myself with the project's status docs and recent history.

Claude — 2026-06-23 14:52

Let me check the latest session log and sprint plan for the current focus.

Claude — 2026-06-23 14:52

Here's where the project stands as of today (2026-06-23):

Mandala (navina) — Project Status

What it is: Drupal 11 rebuild consolidating five legacy D7 sites (AV, Images, Sources, Texts, Mandala Home) into a single Drupal instance, deployed on AWS (Terraform + Ansible + CodePipeline).

Repo state: main is clean. Latest merge is PR #10 (1a.6 scheme migration).

Decisions & Spikes

  • ADRs 001–011 all Accepted. Most recent: ADR 011 (Group collections inheritance — Option D: entity-reference nesting + custom hooks), which closed the Spike 3 question.
  • Spikes: 1 (KMaps field), 2 (Solr/proxy auth), 3 (Group collections) Proven · 8 (reindeer_x) Partial · 4 (CKEditor footnotes), 5 (bibcite), 6 (React API), 7 (Kaltura) Pending.

Active work — Sprint 1: Mandala Images pilot

The Images site is the first vertical slice, mob-built to establish the migration pattern before the codebase forks into per-site tracks. Content model is settled (audit validated against 111,340 production images).

Step 1a — public plumbing:

Task Status
1a.1–1a.3 — shanti_image content type + 3 paragraph types + scheme vocabulary (CMI config) ✅
1a.4 — KMaps field productionized (search_root_kmapid, KmapsPathResolver, D7→D11 mapping) ✅
1a.5 — IIIF wiring (shanti_iiif module, byte-identical URLs to D7, reachability verified) ✅
1a.6 — First migration: scheme nodes → taxonomy terms (mandala_migrations module, Migrate API plumbing) ✅
1a.7 — The pattern-setting image migration (~111k images, node→paragraph satellites) ⏭ next, the big one
1a.8 — Solr write/sync via reindeer_x soft-blocked (Spike 8 + Dave Goldstein convo)
1a.9 — Repeatable test → validate → rollback cycle pending

Step 1b — auth increment (proxy-auth contract, Group collections per ADR 011, Solr-proxy visibility): not started.

Notable findings to carry forward

  • Production has only 2 classification schemes (LCSH + TGN), not the 5–10 assumed.
  • Migrate source DB is wired as a secondary DDEV database (d7_images) from the prod dump; run scoped as drush ms --group=mandala_images to avoid migrate_drupal noise.
  • IIIF server is Cantaloupe 5.0.6, S3-backed; URL contract confirmed identical to D7.

High-priority deferred items

  • solr-sync-architecture-d11 & solr-pipeline-cost-discussion (both blocked on a Dave Goldstein conversation)
  • reindeer-x-aws-credential-strategy
  • images-prod-packaging-monorepo-pass

Natural next move: task 1a.7 — the image migration that sets the template every other site's migration will copy. Worth a dedicated multi-session push since 1a.6 just laid the Migrate API foundation it builds on.

Want me to dig into any area, or start prepping 1a.7?

User — 2026-06-23 15:01

can you rescan all the files

Claude — 2026-06-23 15:01

I'll do a full rescan of the documentation and project structure.

Claude — 2026-06-23 15:01

Let me read the roadmap and critical-path docs to complete the picture.

Claude — 2026-06-23 15:01

Rescan complete. The working tree is clean and there are no new commits since my last summary, so the project state is unchanged — but the full file scan fills in the broader structure. Here's the refreshed picture.

Full Rescan — Mandala (navina)

Repo: clean working tree, on main, 393 config files in drupal/config/sync/. No uncommitted drift.

Custom modules (5)

Module Purpose Status
shanti_kmaps_fields KMaps term-reference field type (Spike 1) productionized through 1a.4
shanti_kmaps_admin KMaps server config in place
shanti_iiif IIIF URL builder + formatter (1a.5) shipped
mandala_migrations Migrate API group + scheme migration (1a.6) shipped
spike_solr_demo Spike 2 read-only Solr demo spike artifact

Documentation inventory

  • 11 ADRs (001–011), all Accepted.
  • 8 spikes: 1, 2, 3 Proven · 8 Partial · 4, 5, 6, 7 Pending.
  • 12 session logs (2026-06-09 → 2026-06-22).
  • 11 deferred notes (9 open, 2 resolved by ADR 011).
  • Planning docs: roadmap, critical-path, images-content-model-audit, kmaps-migration-mapping, refactoring-plan, spikes-plan, collections-inheritance-brief.
  • dev-notes: local-dev howto, run-docs howto, session-workflow rituals.

The bigger arc (from roadmap + critical-path)

The 9-phase plan beyond the current Images pilot: - Phase 0 (parallel, ongoing): Solr cost/architecture convo with Dave Goldstein; cheap go/no-go probes (footnotes, bibcite, Kaltura); Tibetan Unicode normalization triage. - Phase 1 (now): Images pilot — the spine. Step 1a public plumbing ~80% done (1a.1–1a.6 ✅, 1a.7–1a.9 open); Step 1b auth increment unstarted. - Phase 2: fork to parallel tracks — Texts (Than, footnotes/Tibetan), Sources (Xiaoming, bibcite), Collections (Group Option D hooks), Mandala Home. - Phase 3: AV (Kaltura + transcripts, hardest, intentionally last) + React API URL strategy (the cutover gate, Option A/B/C undecided).

Three critical-path risk items (per the assessment doc)

  1. KMaps field type — highest risk; largely retired by Spikes 1 + 1a.4.
  2. Collections/Group architecture — resolved by ADR 011 (Option D); implementation lands in 1b.2.
  3. React API compatibility — still open; needs an Option A/B/C decision with Than/Andres before Phase 5.

Open question flagged in roadmap

AV transcript format (plain vs. structured/time-coded) — if structured, Spike 4 (footnotes) and AV transcript work collapse into one "structured Tibetan rich-text round-trip" proof. Resolve before Phase 3 scoping.

Nothing changed since the last session wrap — the live edge is still task 1a.7, the pattern-setting image migration (~111k images, node→paragraph satellites), which every other site's migration will copy. Want me to start scoping it?

User — 2026-06-23 15:02

let's continue with 1a.7

Claude — 2026-06-23 15:02

1a.7 is the big one — the pattern-setting image migration. Let me orient thoroughly before touching anything. I'll read the audit, the migration mapping, the existing migration module, and check the environment.

Claude — 2026-06-23 15:02

Excellent — I have the full spec. Now let me inspect the existing migration module, the D11 destination config, and verify the environment (DDEV + source DB).

Claude — 2026-06-23 15:03

Let me set up task tracking and verify the environment plus the existing migration pattern.

Claude — 2026-06-23 15:04

DDEV is up, but the d7_images secondary database is gone (DDEV's extra DBs don't persist across restarts the way the primary does). I need to reload the dump. Let me locate it and check the migrate connection config.

Claude — 2026-06-23 15:05

Before going further I hit a real blocker worth surfacing rather than working around.

The source database isn't on this machine. The d7_images secondary DB that 1a.6 loaded is gone — DDEV's extra databases don't survive a restart the way the primary does — and the dump file it was loaded from (mandala-prod-images-db_2026-06-11.sql.gz, 70 MB) isn't here either. The 1a.6 session ran on Yuji's machine, where the dump lived at /Users/ndg8f/Sandbox/Mandala/data/. It's gitignored (*.sql.gz), so it never came across with the repo, and it's not anywhere under your home or ~/Code.

Everything else is ready: DDEV is up, the migrate connection in settings.php points at d7_images, the mandala_migrations module + group exist, and the full D11 destination (the shanti_image content type, the three paragraph types, the scheme vocabulary) is all in place.

So the engineering of 1a.7 — writing the shanti_image node migration plus the node→paragraph transform for the agent/description/classification satellites — I can do against the documented schema in the audit + mapping docs. But 1a.7 is explicitly "the pattern-setting migration," and its whole point is to prove the pattern against real data (count reconciliation, shared-agent fan-out, NFC/NFD fidelity, KMaps round-trip). I can't verify any of that without the dump.

How do you want to proceed?

Claude — 2026-06-23 15:07

You put the dump in the project — let me find it and load it into d7_images.

Claude — 2026-06-23 15:07

Found it at the repo root. Let me set up task tracking, then load the dump into d7_images.

Claude — 2026-06-23 15:08

Now loading the dump into d7_images (this is a 70 MB import, may take a minute).

Claude — 2026-06-23 15:09

The --file form rejected the .sql.gz; the help shows the piped form. Let me create the DB and pipe the dump in.

Claude — 2026-06-23 15:09

Let me check the dump's header, then import directly via mysql (bypassing the finicky import-db wrapper).

Claude — 2026-06-23 15:10

No USE/CREATE DATABASE in the dump — just table DDL. I'll pipe it straight into mysql against d7_images.

Claude — 2026-06-23 15:11

MySQL 8 collation (utf8mb4_0900_ai_ci) isn't supported by DDEV's MariaDB. That's what ddev import-db normally normalizes — but its flag parsing is fighting me. I'll stream-rewrite the collation and import directly. First, what collations appear?

Claude — 2026-06-23 15:11

Only one collation to fix. Let me mark task #1 in progress, recreate the DB clean, and stream-import with the collation rewritten.

Claude — 2026-06-23 15:11

macOS sed chokes on the binary content. Setting LC_ALL=C makes it byte-literal.

Claude — 2026-06-23 15:13

Import succeeded — every node count matches the audit data profile exactly (111,340 images, 103,943 agents, 72,453 descriptions, 13 classifications, 2 schemes). Collation rewrite was clean.

Now task #2 — capturing the pre-migration baseline for reconciliation.

Claude — 2026-06-23 15:13

All baseline counts match the audit profile precisely (agents 111,345 refs / 91,852 distinct; descriptions 55,041; classifications 9). Solid reconciliation targets.

Now let me study the established 1a.6 migration pattern and the known agent-name gap before writing anything.

Claude — 2026-06-23 15:14

Now I understand the established pattern and the agent-name gap. The critical design wrinkle: agent fan-out forces per-reference sourcing — paragraphs are owned by one parent, so shared agents (19,639 refs across 146 agents) must duplicate into one paragraph per referencing image. That means sourcing satellites via the image's reference field, keyed on (image_nid, delta), not 1:1 from the node table. The i3fid also lives in the shanti_images sidecar (keyed by nid), not a field. Both push toward custom source plugins.

Let me nail down the exact D7 schemas before writing anything.

Claude — 2026-06-23 15:15

Key findings: i3fid format is shanti-image-{siid}, KMaps 6-column schema confirmed. Data-quality flag: sidecar has 111,309 rows / 111,308 distinct nids — so ~32 images have no sidecar row (no i3fid), but field_iiif_id is required on D11. I'll need to handle those. Let me verify satellite field schemas and the description/classification title question the deferred note flagged.

Claude — 2026-06-23 15:15

Three data-quality issues surface — exactly what the pattern-setting migration should flush out:

  1. image_descriptions titles are sometimes meaningful ("Participants of Lha...", Tibetan captions) — contradicting the build-time assumption that they're disposable. Need to check if that content is duplicated in field_description/field_summary or would be lost.
  2. external_classification titles look like the concept label ("Birds", "Parrot", "Ritual") — may not be captured by field_external_class_id/_note.
  3. 427 agents have empty titles, but field_agent_name is required — need to know if any are in the referenced set.

Let me quantify all three precisely.

Claude — 2026-06-23 15:16

Decisive findings. The pattern-setting migration just earned its name — it's surfacing real data-quality issues the build-time assumptions got wrong:

  • 49,223 of 55,041 referenced descriptions (89%) have a meaningful, unique title — a caption/headline distinct from description, summary, and author (e.g. title "Crab Nebula" vs description "Donec sollicitudin…" vs summary "Description forthcoming"). The image_descriptions paragraph has no field to hold it — it would be silently dropped. The deferred note explicitly said: if description titles carry real content, add a field. They do.
  • 383 referenced agents have empty titles, but field_agent_name is required → those paragraphs fail.
  • ~32 images lack a sidecar i3fid, but field_iiif_id is required → those nodes fail.

Let me get the last detail (the 9 referenced classifications) before I lay out the decisions.

Claude — 2026-06-23 15:16

I now have the full data-quality picture. Four issues need a modeling decision before I write the migration, because they change CMI config. Here's the evidence:

Issue Evidence Impact
Description titles 49,223/55,041 (89%) have a unique, meaningful caption (title "Crab Nebula" ≠ description ≠ summary) No paragraph field holds it → silent data loss
Classification titles The 9 referenced carry the concept label ("Ritual", "Nebulae", "Parrot") not in class_id/note Lost, but only 9 paragraphs
Empty agent names 383 referenced agents have empty titles (one, nid 637316, fans out to 155 paragraphs) field_agent_name is required → ~537 paragraphs fail
Missing i3fid ~32 images have no sidecar row field_iiif_id is required → those nodes fail

The first two are exactly what the agent-name deferred note told 1a.7 to check ("if those titles carry real content, add equivalent fields") — and they do. Let me get your calls before touching config.

Claude — 2026-06-23 15:20

Good — let me get you the concrete example you asked for before we finalize. Let me find images that reference an empty-name agent.

Claude — 2026-06-23 15:20

Here's the concrete example you asked for.

Empty-name agent nid 637316 (shared, referenced 155 times) is a photographer with a date but no name: field_agent_role = photographer, field_agent_dates = 2014-10-02, name blank. So it's not an empty record — it carries real provenance, just no name. Images using it include:

  • nid 637326 — "A bamboo carrying basket filled with local radish" → https://images.mandala.library.virginia.edu/image/bamboo-carrying-basket-filled-local-radish
  • nid 637336 — "Dried leaves of turnip..." → /image/dried-leaves-turnip-valuable-winter-vegetable-rural-people-bhutan

A one-off empty-name agent (nid 1327696) is on: - nid 1327706 — "Inside View of the Main Temple at Radreng Monastery" → /image/inside-view-main-temple-radreng-monastery

The key implication: "skip those agent refs" would also drop the photographer role + date, not just the blank name — so that option loses more than it looks. That leaves relax-to-optional (keep role/date, empty name) or default-to-"Unknown" (invents a name) as the real choices.

What would you like to clarify or dig into on the remaining two questions (empty agent names, and the ~32 images with no i3fid)? Once you're settled I'll re-pose them and we proceed.

User — 2026-06-23 15:23

let choose default-to-"Unknown" for empty agent

Claude — 2026-06-23 15:24

Got it. Decisions so far: - Description + classification titles → add carrier fields to both, map D7 title verbatim. - Empty agent names → default to "Unknown" (required field stays required, keeps role/date intact).

One decision left — the ~32 images with no i3fid.

Claude — 2026-06-23 15:24

Let me pull the details on those images so you can decide from evidence. Let me look at exactly what the no-i3fid images are.

Claude — 2026-06-23 15:26

The query is running in the background. Let me wait for it.

Claude — 2026-06-23 15:27

The anti-join is slow — shanti_images.nid isn't indexed (only siid is PK). That matters for the migration too (the source will join the sidecar on nid for every image), so let me add the index now, then rerun.

Claude — 2026-06-23 15:29

Now the picture is clear. The no-i3fid images are 36 nodes (slightly more than my earlier estimate), and they're more degenerate than "just missing IIIF":

  • All 36 are published (status=1), all created on a single day — 2018-11-30 — so they're one import batch.
  • They have real metadata: meaningful titles and path aliases (e.g. "Wall of hundred and eight stupas around Kurje Monastery" → /image/wall-hundred-and-eight-stupas-around-kurje-monastery).
  • But they have no image at all — no sidecar i3fid and no field_image file. They're imageless metadata records. On the live D7 site they'd render with no image.

So this isn't 36 images that lost their IIIF link — it's 36 published nodes that never had an image. That sharpens the choice:

  • Relax field_iiif_id to optional → migrate all 111,340 faithfully; these 36 land as imageless nodes (exactly their D7 state), metadata preserved.
  • Skip them → reconcile to 111,304; drops 36 published nodes and their metadata, but keeps the index "every image has an image."

My recommendation is relax to optional — it's the faithful-migration choice (ADR 008), keeps the count whole, and the 36 are no more broken in D11 than in D7. But since these are genuinely imageless, skipping is defensible if you'd rather the D11 shanti_image index guarantee a renderable image.

Which way do you want to go — relax to optional, or skip the 36?

User — 2026-06-23 15:29

please give node id for all 32 images without i3fid

Claude — 2026-06-23 15:29

Note: it's actually 36, not 32 (my earlier 32 was a rows-vs-distinct estimate; the real anti-join gives 36). Here are all of them.

Claude — 2026-06-23 15:29

All 36 node IDs are above. Quick read on the set:

  • 28 are a single 2018-11-30 Bhutan import batch (nids 664581–665061) — coherent real content (Kurje/Ugyencholing monastery photos, cultural shows), just imageless.
  • 8 stragglers: 942421, 979816, 1035966, 1266326 ("Well"), 1444451 ("This is an image caption"), 1444531, 1631157 (Tibetan title འབྲས་སྤུངས་དགོན་པ།).
  • A few smell like test records — 1266326 "Well", 1444451 "This is an image caption".

For reference, the bare list: 

664581 664591 664601 664611 664621 664631 664641 664651 664661 664671
664681 664691 664701 664711 664721 664731 664751 664761 664771 664781
664791 664801 664811 664836 664906 664916 664971 665051 665061 942421
979816 1035966 1266326 1444451 1444531 1631157

You can spot-check any on the live site via its alias (e.g. https://images.mandala.library.virginia.edu/image/well). Once you've looked, let me know: relax field_iiif_id to optional (migrate all 36 as imageless nodes) or skip them (reconcile to 111,304)?

User — 2026-06-23 15:34

relax field_iiif_id to optional

Claude — 2026-06-23 15:34

All four modeling decisions are locked:

  1. Add carrier fields — field_description_title on image_descriptions, label field on external_classification; map D7 title verbatim.
  2. Empty agent names → default "Unknown"; field_agent_name stays required.
  3. Missing i3fid → relax field_iiif_id to optional; migrate all 111,340.

Let me record these and start building. First I'll mirror the existing field_agent_name config to create the two new carrier fields, and read the configs I need to modify.

Claude — 2026-06-23 15:35

I'll flip field_iiif_id to optional and clone field_agent_name for the two new carrier fields. Let me read the paragraph display configs and generate UUIDs.

Claude — 2026-06-23 15:36

All decisions clear. Let me make the config changes — flip field_iiif_id to optional, and add the two carrier fields (storage + field + form/view displays).

Claude — 2026-06-23 15:36

Now wire the new fields into the form and view displays for both paragraph types.

Claude — 2026-06-23 15:37

Now let me import the config and verify the field changes land cleanly.

Claude — 2026-06-23 15:37

The local environment is out of sync with main: migrate_plus/migrate_tools aren't installed (composer deps from 1a.6 were never pulled in here), plus a site-UUID mismatch and leftover shortcut entities. I need to reconcile the environment before importing config. Let me check the actual state.

Claude — 2026-06-23 15:38

This machine has a vanilla Drupal install — shanti_image is missing, the migrate contrib modules aren't installed, and the site UUID differs from main. The local site was never brought up to the merged sprint state. I need to reconcile it before any migration. CLAUDE.md mentions ./scripts/rebuild.sh for a full local rebuild — let me read it.

Claude — 2026-06-23 15:39

The fix is clear: composer deps are declared but never installed, and the local site needs rebuilding from main's config. Both are standard, low-risk here (the local Drupal is vanilla — nothing to lose; the d7_images source DB is a separate database and won't be touched). Let me run composer install first.

Claude — 2026-06-23 15:39

migrate_plus + migrate_tools installed. Now rebuild Drupal from main's config (this also brings in my new field changes).

Claude — 2026-06-23 15:40

--existing-config chokes on the standard profile's hook_install() — a known Drupal limitation. Let me check the documented local-dev sequence rather than guess.

Claude — 2026-06-23 15:40

The documented flow is plain site:install + config:import (rebuild.sh's --existing-config is the broken path). I'll run a fresh standard install, align the site UUID to the committed one, clear the blocking shortcut entities, then import.

Claude — 2026-06-23 15:40

Now import the committed config (builds the full content model + my new fields).

Claude — 2026-06-23 15:41

Config imported successfully — the full content model plus my new carrier fields are now live. Let me verify the environment is coherent before building the migration.

Claude — 2026-06-23 15:43

Environment is now fully coherent — shanti_image, all three paragraph types, both new carrier fields, and field_iiif_id now optional; the d7_images source DB (111,340 images) is intact. That was a necessary detour (the machine had a vanilla install).

Let me run the 1a.6 scheme migration first (the classification paragraphs depend on its map), then build the migration plugins.

Claude — 2026-06-23 15:44

Scheme terms ready (tid=1 LCSH, tid=2 TGN). Now I need the exact D7 column suffixes for every field so the process maps are correct. Let me inspect them in bulk.

Claude — 2026-06-23 15:44

Now the D11 destination field types for the trickier ones (datetime, link, number), so I map formats correctly.

Claude — 2026-06-23 15:45

Key conversions identified (copyright_date datetime reformat, license_url→link/uri). One scope check before I write: does field_image (the actual file) carry data, or is display purely IIIF? That decides whether file-binary migration is in play.

Claude — 2026-06-23 15:47

Decisive scope facts: - field_image (local file): only 545 of 111,340 images have one — display is 99.5% pure IIIF. Migrating file binaries is out of scope (note as deferred); identity rides on field_iiif_id. - field_license_url: 100% coverage — the required link field will always be satisfiable.

I have everything needed. Let me write the two custom source plugins (the reusable satellite fan-out source + the image source with sidecar join).

Claude — 2026-06-23 15:48

Now the four migration definitions. I'll write them into the module's config/install/ (matching the 1a.6 pattern). Starting with the three satellite paragraph migrations.

Claude — 2026-06-23 15:49

field_author is multi-value (-1), summary single. I'll map author over all deltas. Writing the descriptions and classification migrations.

Claude — 2026-06-23 15:50

Now the main shanti_image node migration — mapping the full field set, KMaps, IIIF identity, and the three paragraph reference fields.

Claude — 2026-06-23 15:51

Now I'll activate the new migration config entities and verify the source plugins parse correctly via migration status.

Claude — 2026-06-23 15:52

Migrations registered, source counts look right — but two findings:

  • Agent source = 111,194, not 111,345 → 151 dangling agent references (refs to agent nids that aren't valid image_agent nodes). Those lookups will return null in the host, so I must guard the paragraph sub-process to skip nulls.
  • Descriptions (55,041) and classifications (9) match the baseline exactly — no dangling refs there.

Let me check whether field_image_agents is required (determines if all-dangling images would fail), then add the null-skip guard.

Claude — 2026-06-23 15:53

One more data-quality fork surfaced, and it's a real one: all 151 dangling agent refs belong to 151 images whose only agent reference is dangling — so those images would migrate with zero agent paragraphs, but field_image_agents is required. They'd fail.

This is the same class of decision as the empty-i3fid one. Given you chose "default to Unknown" for empty agent names (keeping provenance present rather than empty), the consistent move here is a synthetic "Unknown" agent for these 151 — but that's more migration machinery. The simpler faithful option is to relax field_image_agents to optional (like we did for i3fid), letting those 151 land agent-less.

Let me add the null-skip guard (needed regardless) while you decide.

Claude — 2026-06-23 15:58

"Relax to optional" — consistent with the i3fid decision. Let me flip that flag and import.

Claude — 2026-06-23 15:59

Field is now optional. Time for the subset test — I'll run the satellites with a limit, then 50 images, with ordering aligned by nid so the lookups resolve.

Claude — 2026-06-23 16:00

All failed — output got truncated. Let me see the actual error on the agent migration.

Claude — 2026-06-23 16:00

The drush cim I ran for the field flag deleted my four migrations from active config — they were only in the module's config/install, not in config/sync, so cim (which makes active match sync) removed them. Classic footgun. Let me recreate them in active config and persist them to config/sync so they survive future imports.

Claude — 2026-06-23 16:01

All five migrations are now in both active config and config/sync (cim-safe). Now the subset test.

Claude — 2026-06-23 16:01

Still failing — let me see the actual error now that the migration exists.

Claude — 2026-06-23 16:02

The bug: my aliased id columns (host_nid) can't be referenced in the auto-generated migrate-map JOIN (MySQL rejects aliases in ON). The idiomatic fix for computed-id sources is to disable the SQL map join (mapJoinable() → FALSE), so migrate filters in PHP instead.

Claude — 2026-06-23 16:03

Satellites migrate cleanly (1000 agents, 1000 descriptions, 9 classifications, 0 failed). Now the image migration subset — the real test of the node→paragraph wiring.

Claude — 2026-06-23 16:03

The dependency check requires the satellite migrations to be fully complete (not partially) before the image migration will run — correct behavior, but it means I can't test images on a subset until satellites finish. The satellite sources are proven (0 failures), so let me run them to completion, then test the image wiring on a subset. Running the two big satellites in the background.

Claude — 2026-06-23 16:04

Satellites are running in the background (111k agents + 55k descriptions — a few minutes). Let me check progress shortly.

Claude — 2026-06-23 16:04

Progress writes only on completion (piped through tail). While the satellites run, let me verify the active shanti_image migration config — specifically that the YAML anchors for the KMaps fields expanded correctly when saved to active config.

Claude — 2026-06-23 16:05

Config is correct — anchors expanded, paragraph wiring intact. Let me check satellite progress.

Claude — 2026-06-23 16:05

The migration build is complete and validated on a subset — I'm now waiting on the two full satellite migrations (111k agents + 55k descriptions) running in the background before I can test the image-node wiring (the dependency check requires them complete).

Where 1a.7 stands:

Built and proven: - Two custom source plugins — D7ImageSatellite (per-reference fan-out + orphan skip) and D7ShantiImage (sidecar i3fid join + paragraph lookup keys). - All four migrations (3 satellite paragraph + the shanti_image node), with KMaps column-copy, IIIF identity, datetime/link conversions, and null-skip guards for dangling refs. - Subset test passed: 1000 agents, 1000 descriptions, 9 classifications — 0 failures.

Config-model changes landed (your four decisions): - field_description_title + field_external_class_label carrier fields added. - field_iiif_id, field_image_agents → optional; empty agent names → "Unknown".

Also reconciled the environment — this machine had a vanilla Drupal install, so I composer-installed the migrate modules and rebuilt the site from main's config first.

I'll report back as soon as the satellites finish and I've run the image-node subset test + count reconciliation.

Background command "Run full satellite migrations" completed (exit code 0)

Claude — 2026-06-23 16:15

Agents fully migrated (111,194 total, 0 failures). But descriptions failed partway. Let me see the error.

Claude — 2026-06-23 16:17

Descriptions are effectively complete (55,038/55,041, 0 unprocessed) — the earlier "failure" aborted the batch but the re-run shows nothing left. 3 rows didn't import. Let me find out what happened to them.

Claude — 2026-06-23 16:17

3 description rows are IGNORED (status 3, not failed) — migrate found nothing to import for them; 55,038 imported, 0 unprocessed, 0 failed. The dependency is satisfied. Now that all satellites are complete, let me run the image-node subset test and inspect a result in depth.

Claude — 2026-06-23 16:17

50 images migrated, 0 failures. Now the critical validation — let me deeply inspect one migrated node to confirm the full graph round-trips: fields, KMaps, IIIF, and the node→paragraph wiring.

Claude — 2026-06-23 16:18

The graph round-trips beautifully — IIIF identity from the sidecar (shanti-image-16, 3864×3864), the agent paragraph (NASA/photographer) and description paragraph with the new field_description_title carrier field ("Crab Nebula", distinct from summary/description). The node→paragraph fan-out and carrier-field decisions are validated.

KMaps are empty on this low-nid seed node, though. Let me confirm KMaps actually migrate by finding a migrated image that had subjects in D7.

Claude — 2026-06-23 16:18

KMaps look empty on the migrated node — D7 nid 221 had subjects but D11 node 5 shows none. Let me check whether it's a display bug or a real migration gap by querying the D11 storage directly and the source row.

Claude — 2026-06-23 16:21

field_subjects didn't migrate (D11 storage empty, D7 source has data). The slow source-iteration eval is still churning — let me kill it and run targeted diagnostics. Note the D7 raw format is angle-bracket ancestors, not the pipe format the mapping doc assumed — but the real issue is the field isn't transferring at all.

Claude — 2026-06-23 16:22

field_subjects loads, is active, no errors — yet nothing migrated. Let me see exactly what keys the d7 source exposes on the first row (fast, no full iteration) to find the mismatch.

Claude — 2026-06-23 16:22

timeout isn't on the host — dropping it; grabbing just the first row is fast.

Claude — 2026-06-23 16:23

The source exposes KMaps correctly (keys raw/id/header/domain/path/defids, real data). So the gap is on the destination side — the D11 field's property names must not match my sub_process keys. Let me check the D11 KMaps field type definition.

Claude — 2026-06-23 16:24

D11 properties match exactly (raw/id/header/domain/path/defids) — so the mapping should work, yet node__field_subjects is totally empty. Notably, simple fields and the paragraph sub_processes worked, but the KMaps sub_processes didn't. Let me rollback and re-run one tagged node with full verbosity to watch the process.

Claude — 2026-06-23 16:26

While the single-node import runs, let me read the KMaps field type — a setValue/preSave that derives columns from raw would explain blanked values.

Claude — 2026-06-23 16:27

Found the root cause. KmapsItem::isEmpty() (line 134–141) treats an item as empty unless raw has ≥3 pipe-delimited segments (id|header|domain|path|defids). But D7 production raw is angle-bracket ancestors (<5805> <1808> <2163>) — no pipes — so every KMaps item is judged empty and silently dropped on save. The mapping doc's assumed raw format doesn't match production data.

I need to know the canonical D11 raw format (what the widget/formatter produce) to fix this correctly. Let me check the widget, and confirm the failed node.

Claude — 2026-06-23 16:29

The canonical D11 raw is id|header|domain|path|defids (the widget's itemToRaw() builds it that way; the formatter reads the separate columns). So the migration must construct raw in that format from the D7 columns, not copy D7's angle-bracket raw. That satisfies isEmpty() and keeps the field editable. Let me confirm the failed node, then fix.

Claude — 2026-06-23 16:30

Confirmed: D7 221 → D11 node 51, subjects = 0. The fix is to construct raw via concat of the columns. Let me update the KMaps mapping in all three migration files (the shanti_image anchor covers its 4 fields; plus field_agent_place and field_language in the satellites).

Claude — 2026-06-23 16:30

Now activate the fix — recreate the three migration configs from the corrected module files (map tables persist), re-export, and confirm raw now builds via concat.

Claude — 2026-06-23 16:32

raw now builds via concat in active config. Let me validate the fix cheaply on an image subset before committing to a full re-run — rollback images, re-run 50, and check KMaps populate.

Claude — 2026-06-23 16:32

Both failed — let me see why.

Claude — 2026-06-23 16:33

The migration is stuck in a stale "Importing" lock (from the earlier interrupted background run). Let me reset it and retry the subset.

Claude — 2026-06-23 16:34

KMaps fix works — node__field_subjects now has rows; node 56 (D7 221) shows id=2163, header, domain, and the correctly-rebuilt pipe-composite raw=2163|Flight of small birds dö|subjects|{{Ritu.... The image-level KMaps migrate correctly now.

Before committing to a full re-run, let me measure real image throughput (the image migration is the slow part — per-image sidecar + 3 paragraph lookups + 48 fields) with a timed 2000-image batch.

Claude — 2026-06-23 16:36

~40 images/sec → the full image migration is ~50 min. Let me confirm the 2000 batch is healthy, then launch a full clean run (rollback + reimport everything in dependency order) in the background — that's the safe way to get the KMaps fix into the satellites too, since --update on already-referenced paragraphs would orphan revision IDs.

Claude — 2026-06-23 16:37

Most fields look healthy (KMaps populating, IIIF 100%, agents ~1:1), but desc_refs=21 for 2000 images looks low — baseline says ~43% of images have descriptions (~860 expected). Let me check whether it's sample bias (these source-order-first images genuinely lack descriptions) or a broken lookup.

Claude — 2026-06-23 16:37

Confirmed — it's sample bias, not a bug: of these 2000 source-order-first images, only 19 have descriptions in source, and all 19 resolved (21 refs). The pattern is now fully validated end-to-end:

Check (2000-image batch) Result
Images created 2000 / 2000, 0 failed
field_iiif_id populated 2000 (100%)
KMaps field_subjects rows 1,573 (now populating after the fix)
Agent paragraph refs (fan-out) 2,001 (~1:1)
Description refs 21 (matches 19 source images — lookups resolve)

Let me mark the build tasks done. The remaining question is the full 111k run: at ~40 img/sec it's ~50 min for images plus re-running the satellites with the KMaps fix (~15 min) — and Sprint 1's acceptance criteria actually locate the full production migration in staging (task 1a.9), not on dev.

Claude — 2026-06-23 16:37

How would you like to handle the full run?

Claude — 2026-06-23 16:38

Launching the full clean run in the background — rollback all four in reverse dependency order, then reimport in dependency order, with progress logged.

Claude — 2026-06-23 16:39

The full run is going in the background (~65–80 min). Let me verify it started cleanly, then use the time to document the key 1a.7 findings while it churns.

Claude — 2026-06-23 16:39

The shanti_image rollback failed — likely --no-progress isn't valid for migrate:rollback. The script continues without -e, which would corrupt the clean run (stale rows remain). Let me stop it and check.

Claude — 2026-06-23 16:40

Confirmed — migrate:rollback rejects --no-progress (only --feedback), so all rollbacks in the running script are failing and the reimports would skip already-migrated rows. I need to kill it and restart with a corrected script.

Claude — 2026-06-23 16:40

Killed cleanly, all Idle. Let me fix the script (--feedback works for both rollback and import) and relaunch.

Claude — 2026-06-23 16:41

Let me confirm the rollbacks work this time before letting it run.

Claude — 2026-06-23 16:41

While it runs, let me verify the first rollback succeeded (the bug that corrupted the last run).

Claude — 2026-06-23 16:41

Rollback still churning (2000 items). While the full run proceeds, let me document the most important technical finding — the KMaps raw format discovery, which corrects the migration mapping doc and matters for replicating the pattern to other sites.

Claude — 2026-06-23 16:42

Still rolling back the large satellites (one line logged per step). Rather than poll, I'll let the completion notification fire and keep documenting. Let me write the second finding — the deferred field_image binary migration.

Claude — 2026-06-23 16:42

Rollbacks now working correctly (shanti_image rolled back 2000, onto the satellites). The full run will churn for ~an hour. Let me prepare the session-end artifacts while it runs. First, index the two new deferred notes.

Claude — 2026-06-23 16:42

Deferred notes indexed. Let me check migration progress.

Claude — 2026-06-23 16:43

The full clean run is proceeding correctly now (shanti_image + classification rolled back; descriptions rolling back, then agents, then the four reimports in dependency order). It'll churn for ~an hour in the background — I'll be notified when it completes and will do the final 111,340-row reconciliation then.

Status while it runs:

✅ Build complete & validated (2000-image batch, 0 failures): the node→paragraph fan-out, KMaps (after the raw-rebuild fix), IIIF identity, carrier fields, and dangling-ref handling all confirmed working.

✅ Documented two key findings as deferred notes (indexed): - kmaps-raw-format-rebuild-on-migration (High) — the D7 raw is angle-bracket ancestors, not the pipe composite the D11 field needs; copying it caused silent KMaps loss. Migration now rebuilds raw via concat. Affects every site's KMaps migration. - images-field-image-binary-migration (Low) — 99.5% of images display via IIIF; the 545 local file binaries are deferred.

Still to do after the run finishes: final count reconciliation against the baseline, then the session-end ritual (sprint doc 1a.7 row, session log, branch + commit + PR like 1a.5/1a.6). The scratch migration script at the repo root will be removed before commit.

I'll report back with the reconciled numbers once the background run completes.

Background command "Run corrected full migration in background" completed (exit code 0)

Claude — 2026-06-23 18:55

The full run completed. Let me read the final status and reconcile.

Claude — 2026-06-23 18:55

Full run complete — all 111,340 images migrated, 0 failures. Let me run the full reconciliation and investigate the 3 ignored descriptions (which also caused that non-zero exit).

Claude — 2026-06-23 18:56

All four node-level KMaps counts match the baseline exactly (subjects 79,337 · places 68,755 · terms 61,668 · collections 83,494) — strong proof the raw-rebuild fix is faithful across all 111k. Let me explain the remaining deltas (orphan-skip is expected to cause some) and find the 3 ignored descriptions.

Claude — 2026-06-23 19:24

Both deltas now fully explained:

  • Language KMaps: 7,303 in D11 = exactly the count on referenced descriptions (7,459 total − 156 on orphaned descriptions). Orphan-skip working perfectly. ✓
  • Agent paragraphs: 111,194 referenced = exact (111,345 refs − 151 dangling). But 111,345 rows exist → 151 orphan paragraphs left over from earlier experimentation that the map-based rollback didn't catch (wouldn't happen on a fresh staging DB). Cleanup needed.
  • The 3 ignored descriptions are a real bug: field_summary is string(255) in D11 but 3 D7 summaries exceed 255 chars → "Data too long". That's lossy.

Let me size the fix and clean the orphans.

Claude — 2026-06-23 19:25

The 3 ignored rows are a genuine model bug: field_summary is string(255) but D7 summaries reach 750 chars. The faithful fix is to widen it. Let me try increasing max_length (a non-destructive varchar widening Drupal can apply with data present).

Claude — 2026-06-23 19:26

Drupal blocks the widening while data exists (expected). The max_length: 1024 fix is correct and will apply cleanly on a fresh install (staging, or rebuild.sh) where the field is created at 1024 with no data — so it's safe to commit; only this already-populated local DB can't hot-apply it. I'll commit the fix and document it rather than burn another 60-min cascade for 3 rows.

Let me clean the 151 leftover orphan paragraphs and do the final validation (including an NFC/Tibetan fidelity spot-check — an acceptance criterion).

Claude — 2026-06-23 19:27

Orphans cleaned (151 deleted). The NFC check got mangled by shell quoting — let me rerun it cleanly and confirm the final agent count.

Claude — 2026-06-23 19:28

php:script resolves paths inside the container. Let me write the script into the project (mounted) and run it with the container path.

Claude — 2026-06-23 19:28

Everything checks out: - Tibetan title round-trips perfectly (འབྲས་སྤུངས་དགོན་པ།, NFC-normalized) ✓ - Diacritic transliteration ("Flight of small birds dö") NFC-preserved ✓ - Agent paragraphs: exactly 111,194 after orphan cleanup ✓

1a.7 is migrated and fully reconciled. Let me close the task, remove scratch files, and review the full diff for the commit.

Claude — 2026-06-23 19:29

Status is as expected, but four KMaps field instance configs show as modified that I didn't intentionally edit (field_subjects, field_places, field_kmap_terms, field_agent_place). Let me check what changed — likely cex normalization drift to revert, or something real.

Claude — 2026-06-23 19:30

Benign — cex made the implicit search_root_kmapid: null explicit on the no-root KMaps fields (correct, matches their actual config; the rooted fields keep their values). I'll keep them. Everything is ready to document and commit.

Let me update the sprint doc with the 1a.7 completion row.

Claude — 2026-06-23 19:31

Now a brief deferred note for the field_summary fix (so the staging run verifies the 3 affected rows), then index it.

Claude — 2026-06-23 19:31

Documentation flushed and indexed. Now the session log and commit. Let me check the session-log script.
