Session Log: Kmasset Contract Images Inventory

Date: 2026-06-25
Participants: Yuji Shinozaki, Claude Opus 4.8
Outcome: Completed Phase 1 of the 1a.8 KMasset Solr Doc Contract — the Images field inventory (§7), extracted from the D7 producer chain and reconciled against live kmassets docs sampled via the proxy on VPN. Key results: the Images doc is built by a 3-module alter chain (shanti_kmaps_fields base + shanti_collections access-path fields, the 1a.8↔1b seam, + shanti_images), not one builder; images carry no *_tibt/*_bo or names_txt fields and encode language via *_lang_s companions (resolving the §8/§10 Q3 open question for Images); fields are largely dynamic-field realized (suffix is load-bearing; suffix-matching fields like rotation_s need no schema deploy); and §7.2-D confirmed against schema.xml (prod == staging, byte-identical) — ids/str/titles/names/creators/descriptions are copyField aggregations the writer must not emit. Added 3 golden JSON fixtures as the writer's acceptance check, and a deferred note for the never-emitted-but-wanted rotation_s (D7 $sdog typo). Committed + pushed as 597db2b.

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

OK. What should we implement next in the current spike?

Claude — 2026-06-25 15:22

Let me orient myself per the session-startup ritual before recommending anything.

Claude — 2026-06-25 15:22

The branch and recent commits are all about the kmasset Solr doc contract. Let me see what's actively in flight — the latest session log and the most relevant spike docs.

Claude — 2026-06-25 15:22

Let me read the two most recent session logs to understand exactly where we left off and what was teed up next.

Claude — 2026-06-25 15:22

I have full context now. Let me check the current state of the contract doc's §7 (the part explicitly marked as the next-step TODO).

Claude — 2026-06-25 15:23

Got it — Sprint 1, not Spike. That actually makes the answer cleaner, because everything from the last two sessions was groundwork for one specific sprint task.

Where Sprint 1 stands

Step 1a (Images pilot, public plumbing) is essentially done — 1a.1–1a.7 all landed on main. Two tasks remain open:

  • 1a.8 — Solr write/sync (image docs land in kmassets and are retrievable)
  • 1a.9 — rollback story (staging prod-DB run → validate → rollback)

1a.8 is the one you've been actively de-risking. The last two sessions produced the foundation half of it: docs/planning/kmasset-solr-doc-contract.md — topology (settled), write transport (open A/B/C), the source chain, the generative grammar, and the schema type layer. And you corrected the two factual errors (kmassets are flat; mediabase is A/V).

What to implement next: Phase 1 of the golden doc

The contract doc's §7 (Images field inventory) is still marked "Phase 1 TODO." That's the literal next step, and it's the highest-value one because it converts the contract from understanding into a testable spec — which is what makes the eventual A/B/C transport choice low-stakes.

Concretely, Phase 1 is:

  1. Open the D7 producer — shanti_images (Images builder) + shared shanti_kmaps_solr, find the function that assembles the JSON written to solrdocs/, and extract the Images field-by-field derivation. (Not mediabase — that's A/V, per the correction.)
  2. Reconcile against the three other authorities already mapped: the 7.x kmassets schema (types), mandala-om (consumer reads), and reindeer_x kmassetSync (shared core) — flagging the known open items (caption_eng vs *_en; the access fields node_user/collection_uid_path_ss that are the 1a.8↔1b seam).
  3. Capture a live kmassets Images sample as a golden fixture (needs you on VPN, or a ! curl dump — flagged as the one thing requiring you).
  4. Write §7 + commit the fixture as the acceptance test for the D11 writer.

This is flat-doc, Images-only work now — no block-join, no mediabase — so it's narrower than the foundation sessions implied.

The thing I genuinely need from you before going deep is the live-index reachability question — otherwise I build §7 from the D7 builder + schema (the defining authority anyway) and treat live-sampling as a later verification pass.

Want me to kick off Phase 1 now (open the shanti_images doc-builder and draft §7), and how do you want to handle the live sample — VPN, a curl dump, or defer it?

User — 2026-06-25 15:24

I'm on VPN, so live queries would be great.

Claude — 2026-06-25 15:25

Let me confirm reachability with a small query and simultaneously locate the D7 shanti_images doc-builder.

Claude — 2026-06-25 15:25

Live queries work — that's a real Images doc from the index. Let me pull the complete document and locate the D7 builder code.

Claude — 2026-06-25 15:26

61 fields in the live doc. Now let me find where that doc gets built in D7 — the pogrified_s: "fields_module" hint suggests a shared builder rather than shanti_images itself.

Claude — 2026-06-25 15:26

The pogrified_s/mogrified_s fields are distinctive — let me trace them straight to the builder, and check shanti_images.module for the doc assembly.

Claude — 2026-06-25 15:27

Key architectural find: the doc builder lives in shanti_kmaps_fields (the pogrify/mogrify source), and shanti_images only alters the base doc via hook_kmaps_fields_solr_doc_alter(). That's the same module name that exists in D11 today — but D11 only has its read side. Let me read both halves.

Claude — 2026-06-25 15:27

_shanti_kmaps_fields_get_solr_doc() at line 1039 is the core builder. Let me read it in full, plus the asset-type definition and the image alter hook.

Claude — 2026-06-25 15:27

This is the generative core — flat doc, site-configured asset_type/URLs, extra-fields mapping, then drupal_alter('kmaps_fields_solr_doc'). Now the Images-specific layer and the extra-fields definition.

Claude — 2026-06-25 15:27

I now have the complete producer picture: the flat base builder + the Images alter hook. Let me pull a few representative live fixtures — multi-description and Tibetan/diacritic docs — to lock the contract's edge cases.

Claude — 2026-06-25 15:28

The caption_lang_s facet reveals a real data-quality landmine: language is stored inconsistently — both en and English, both Tibetan and Standard Tibetan. That's the field_language->header vs default-en split from the builder code. Let me confirm whether Images docs carry any Tibetan-script (*_tibt/*_bo) fields at all, then read the §7 placeholder to match the doc's style.

Claude — 2026-06-25 15:28

Decisive finding: Images docs carry no Tibetan-script (*_tibt/*_bo) fields at all — and not even names_txt. So the Images writer emits plain Unicode title/caption/summary/description + _lang_s companions; NFC fidelity applies to those, not to script-suffixed fields. asset_subtype is real and meaningful (mostly photograph). Let me read the current §7 placeholder and surrounding sections to match style before writing.

Claude — 2026-06-25 15:29

The live doc has collection access-path fields (collection_uid_path_ss, collection_uid_s, collection_nid_path_is) that the base builder does not write — so a third alter hook populates them. Given shanti_collections was the other pogrify/mogrify source, let me confirm it owns the §9 access-control fields.

Claude — 2026-06-25 15:30

Confirmed — shanti_collections is a third producer in the alter chain, and it owns exactly the §9 access-control fields. I now have the complete, evidence-grounded picture. Let me write §7.

Claude — 2026-06-25 15:39

Now let me reconcile the open questions in §8/§10 with what Phase 1 resolved, and save the fixtures into the repo so they're not stranded in scratchpad.

Claude — 2026-06-25 15:41

Let me give the fixtures a home in the repo so they're not stranded, and point §7.4 at it.

Claude — 2026-06-25 15:41

Phase 1 is done — the contract's §7 is no longer a TODO. Here's what the live-query extraction produced.

What I found (grounded in producer code + live index)

The Images doc is built by a 3-module chain, not one builder — this is the headline for the eventual D11 writer:

  1. shanti_kmaps_fields → common-core base (identity, KMaps linkage, visibility, URLs)
  2. drupal_alter() fans out to two more producers:
  3. shanti_collections → the collection access-path fields (collection_uid_path_ss, etc.) — i.e. the §9 ↔ Sprint 1b security seam. Not shanti_images.
  4. shanti_images → caption/description/IIIF/dimensions
  5. post-alter normalization (sort keys, URL rewrite, NFC entity-decode)

A writer that only ports the shanti_images layer would silently drop the access-control fields and break 1b. That coupling is now documented.

Live-index findings that sharpened the contract: - Images carry no *_tibt/*_bo script fields — and no names_txt (all verified 0 of 111,326 docs). NFC fidelity for Images lives in plain title/caption/summary/description, not in script analyzers. This resolves the §8/§10 _eng-vs-_en open question for Images (that grammar is kmterms-only; Images uses *_lang_s companion strings). - *_lang_s values are dirty — en (41,561) and English (6,541), Tibetan and Standard Tibetan. A normalize-or-preserve decision for the search phase. - A latent D7 bug: rotation_s is never written ($sdog typo at shanti_images.module:1747) — flagged so we don't reproduce it.

What changed in the repo (working tree, branch docs/kmasset-solr-doc-contract, uncommitted)

  • docs/planning/kmasset-solr-doc-contract.md — §7 fully written (3-layer chain + field inventory tables A/B/C/D), §8 + §10 Q3 reconciled with the resolution.
  • docs/planning/kmasset-fixtures/ — 3 golden JSON fixtures (baseline, multi-description, Tibetan/diacritic) as the writer's acceptance check.

One scope note for your eye: §7.2-D flags ids/str/titles/creators as probable schema copyField destinations the writer must not emit — I inferred that from the builder not writing them, but haven't confirmed against the copyField directives in schema.xml. That's a 5-minute verification if you want certainty before it hardens into the contract.

Want me to (a) verify those copyFields against schema.xml and then commit, (b) just commit as-is, or (c) hold for your review first?

User — 2026-06-25 15:47

notes / questions: 1. rotation_s is something we want to support in the future (regardless of the bug). 2. we didn't see an alt_description_* field in your lists of fields but you mention it in your discussion.

Claude — 2026-06-25 15:47

Good catches — let me verify both against the actual data.

Claude — 2026-06-25 15:48

Both verified — here's the precise picture:

On the alt fields: the field names are {base}_alt_{suffix} (e.g. caption_alt_txt, description_alt_txt, summary_alt_txt, *_alt_lang_ss, description_alt_type_ss, description_alt_authors_ss) — those are in my §7.2 table C. The reason you didn't see them in the field dump: that dump was the baseline doc 1028396, which is single-description, so the builder writes none of them. They appear only on multi-description images — the 1087551 fixture carries the full set (shown above). So it's a presence-conditional family, which the inventory should state explicitly rather than imply.

On rotation_s: good — that reframes it from "don't reproduce the bug" to "the D7 typo is why it's absent in all 111k live docs, and the D11 writer should populate it correctly." Let me fix both in the doc.

User — 2026-06-25 15:50

but be aware that we also have used dynamic fields

Claude — 2026-06-25 15:50

That's an important constraint to bake in — and it actually changes the §7.2-D framing and the rotation_s story. Because the image fields are largely realized through dynamic-field suffix matching (not static declarations), the suffix on each field is load-bearing (it sets the type), and adding a suffix-matching field needs no schema.xml deploy. Let me correct the rotation_s finding and make the dynamic-field reality explicit in §7.

Claude — 2026-06-25 15:52

Now let me make the dynamic-field reality explicit at the top of the inventory and sharpen the §7.2-D distinction (suffixed = dynamic-matched; unsuffixed aggregations = static/copyField).

Claude — 2026-06-25 15:54

Now the deferred note for rotation_s and its registration. Let me check the deferred .pages and an existing note's header format.

Claude — 2026-06-25 15:56

Now register the new note in both the README table and .pages.

Claude — 2026-06-25 15:57

Both addressed, plus the dynamic-field point woven through. Summary of the doc changes (all on branch docs/kmasset-solr-doc-contract, still uncommitted):

1. rotation_s — now treated as a wanted field, not a bug to omit - §7.2-C lists it as "wanted, not yet emitted"; §7.3.4 reframed: the D7 $sdog typo is why it's absent in all 111k docs, and the D11 writer should populate it from $siimg->rotation. - New deferred note docs/deferred/images-rotation-field-support.md, registered in the README table and .pages.

2. The *_alt_* description fields — clarified, not missing - They were in §7.2-C (caption_alt_txt, description_alt_txt, summary_alt_txt, *_alt_lang_ss, description_alt_type_ss, description_alt_authors_ss) — naming is {base}_alt_{suffix}. - You didn't see them because the baseline dump (doc 1028396) is single-description, so the builder writes none. They appear only on multi-description images (≥2 descriptions); fixture 1087551 carries the full set. New §7.3.5 states this presence-condition explicitly, and the table rows are flagged conditional.

3. Dynamic fields — now explicit (your latest note) - New lead paragraph in §7.2: most image fields are dynamic-field realized, so the suffix is load-bearing (sets type/cardinality) and a suffix-matching field can be added with writer code alone, no schema.xml deploy. - That's exactly why rotation_s (*_s) is cheap to add — noted in §7.3.4 and the deferred note. - §7.2-D reframed as the unsuffixed fields (ids, str, titles, creators, timestamp, _version_) — the only ones needing static declaration / copyField, since they fall outside the dynamic grammar.

The one thing still worth a quick check before this hardens: confirming those unsuffixed aggregations (ids/str/titles/creators) really are copyField destinations in schema.xml (vs. written by some producer I haven't traced). Want me to verify that against the configset and then commit, or commit as-is?

User — 2026-06-25 15:58

yes, let's do the analysis of the copyFields

Claude — 2026-06-25 15:58

Let me pull the copyField and field declarations for those unsuffixed aggregations from the deployed 7.x schema.

Claude — 2026-06-25 15:59

Confirmed — but let me make sure I'm reading the production configset, not staging (the find grabbed staging), and that they agree.

Claude — 2026-06-25 15:59

Confirmed and production-verified. The copyField analysis settles §7.2-D — no more hedge needed. Let me finalize that section with the evidence.

Claude — 2026-06-25 16:00

The copyField analysis is done and the result confirms §7.2-D with no hedge remaining.

copyField findings (production-verified; prod == staging, byte-identical)

All six unsuffixed aggregations are statically declared + copyField-fed — the producer chain never writes them:

Aggregation Fed from
ids uid, id, *_id_s, *_id_ss
titles title, title_*, *_title_s, caption
names name, name_*, names_txt
creators creator, creator_*, contributor_*, agent_*, *_authors_s(s), node_user_*
descriptions caption, summary, description, caption_*, summary_*
str universal catch-all (all title/name/creator/id/caption variants, incl. Tibetan *_bo/*_tibt)

Plus timestamp (required, default="NOW") and _version_ (Solr-internal).

The useful half of the finding: the aggregations are automatic, so the writer only emits the source fields (tables A–C) and the search-spanning fields build themselves. Concretely — description_authors_s/node_user_full_s → creators; caption_alt_txt/summary_* → descriptions; shanti_image_id_s → ids. And caption deliberately fans into titles + descriptions + str. That's now written into §7.2-D as guidance, not just a prohibition.

§7 is complete

The contract's Images section is now fully evidence-grounded: producer chain, field inventory (A–D), dynamic-field reality, the resolved language-suffix question, the dirty *_lang_s values, conditional *_alt_* family, and rotation_s as wanted-future.

Working tree (branch docs/kmasset-solr-doc-contract, uncommitted)

  • docs/planning/kmasset-solr-doc-contract.md — §7 written; §7.2-D confirmed; §8/§10 reconciled
  • docs/planning/kmasset-fixtures/ — 3 golden JSON fixtures
  • docs/deferred/images-rotation-field-support.md — new note (+ README + .pages)

Ready to commit. Want me to commit all of this on the branch (and push), or hold for your review first?

User — 2026-06-25 16:02

commit it and push

Claude — 2026-06-25 16:02

I'll stage, commit, and push everything on the branch.

Claude — 2026-06-25 16:02

Committed and pushed to docs/kmasset-solr-doc-contract as 597db2b.

7 files in the commit: - docs/planning/kmasset-solr-doc-contract.md — §7 written, §7.2-D confirmed - docs/planning/kmasset-fixtures/ — 3 golden JSON fixtures - docs/deferred/images-rotation-field-support.md + README + .pages

That closes out the golden-doc extraction (Phase 1) for Images. The contract is now a testable spec: when the D11 Images writer gets built, it emits the table A–C source fields, and the fixtures + copyField rules give you a byte-level acceptance diff.

Two natural follow-ons when you next pick up 1a.8, neither needed now: - The remaining §10 open questions are still the real gates — the write transport (A/B/C) pending the Dave Goldstein cost conversation, and the master write endpoint/auth. - This was Images only; Sources/Texts/AV will each need their own §7-style inventory, but they reuse the common-core (table A) + the copyField behavior you just verified.

save the session log

Claude — 2026-06-25 16:03

I'll run the session-end ritual. Let me find this session's transcript and run the save script.

Claude — 2026-06-25 16:04

The current session is 735eb1bf-... (matches my scratchpad path). Let me see how the script sets the output filename and outcome line.
