Description

Two follow-ups from #653.

generate-patch.ts no longer mirrors build-sqlite.ts (#657)

The issue reported thirteen unsynchronized hardware child tables. Auditing the
other four generators found the gap is wider: build-sqlite.ts writes ~60
tables and generate-patch.ts wrote 16. Beyond the missing tables it also

  • wrote raw markdown into columns the app renders as HTML (build-sqlite.ts
    runs markdownToHtml),
  • inserted category aliases without normalization or dedup,
  • never wrote supersedes_id, release_date_year_only, FTS search_terms,
    manufacturers_fts, manufacturer_search_terms or manufacturer_translations,
  • interpolated toVersion into SQL unescaped, and stamped it unconditionally.

Hand-writing 44 more blocks would keep the drift and add to it, so the script
now takes the shape the issue suggested: it reflects the table graph out of the
built schema and reads the rows back out of a freshly built catalog.sqlite.
One encoder exists, and a new child table or column is carried for free.

Four things that fell out of doing it that way:

  • The root row is upserted, not deleted and reinserted. Another entry's
    supersedes_id can point at it, and dropping the row trips that foreign key
    even though it is about to come straight back. Caught by applying a real
    patch with foreign_keys = ON.
  • A nested row resolves its parent by natural key. hardware_variants.id
    is assigned per build, so a target database has its own numbering and
    carrying the build's ids across would attach variant prices to the wrong
    variant.
  • The version stamp is written only when every change resolved, and the
    script exits non-zero and writes nothing otherwise. That is defect 3 of the
    issue, handled by refusing the patch rather than by making one line
    conditional.
  • Child-table depth is assigned from the previous pass only. A first cut
    let a table discovered mid-pass parent its own child at the same depth, which
    happened to work on the real schema purely because of the order
    sqlite_master lists tables. The unit test caught it.

Verification, beyond the unit tests: built a database from HEAD~6 data, built
one from HEAD, generated the patch, applied it statement by statement, then
compared every table for all 270 changed entries against the full rebuild.
Zero mismatches. A synthetic commit covering all five collections plus a
deletion and a variant-price entry was checked the same way.

Known limitation, documented in the file and in CLAUDE.md: a patch only
rewrites entries whose YAML changed, so renaming a manufacturer leaves the
denormalized manufacturer_name stale in the FTS rows of its unchanged
products. Ship a full database when manufacturer names move.

Dead Pioneer DJ manual links (#654)

The whole downloads.support.alphatheta.com/manuals/ tree is gone; AlphaTheta
moved manual content into support articles. EFX-1000 has a dedicated
Specifications article carrying exactly what the dead ?page=28 anchor pointed
at, so it keeps its title. The other six get the instruction-manual article and
are retitled, since no per-page anchor exists to link any more.

The rot is much wider than the issue's seven entries. data/ holds 260
links under that dead tree across 12 product families; a 12-URL sample all
404s. 210 of those 260 files carry a support.alphatheta.com/products/… link
the replacement article can be resolved from, so it is mechanizable, but it is
253 files beyond this issue's scope and is filed separately rather than widened
into here.

Type of Change

  • Update to existing entry
  • Bug fix
  • Schema or script change

Checklist

  • I have run pnpm validate and it passes
  • YAML files follow the existing format
  • Manufacturer exists (or I'm adding it in this PR)
  • Categories and formats are from the schema files
  • Identifiers are accurate, if provided (bundle IDs, etc.) — no identifiers touched

Additional Notes

pnpm patch is still wired into no workflow, so none of this is a live outage.
pnpm test (306 passing, 11 new), pnpm lint, pnpm typecheck and
pnpm validate all clean.

Fixes #657
Fixes #654

The downloads.support.alphatheta.com/manuals tree
no longer exists, so every link under it 404s.
AlphaTheta moved manual content into support
articles.

EFX-1000 has a dedicated Specifications article
holding the same content the dead ?page=28 anchor
pointed at, so it keeps its title. The other six
get the instruction-manual article and are
retitled, since the per-page anchor no longer

Fixes #654

Co-Authored-By: Claude <noreply@anthropic.com>
generate-patch.ts encoded the YAML a second
time and covered 16 of the ~60 tables that
build-sqlite.ts writes. A patched database kept
stale io, prices, links, versions and variants,
held raw markdown in HTML columns, and carried
unnormalized category aliases.

It now reflects the table graph from the built
schema and reads rows back out, so one encoder
exists and a new child table is picked up
automatically. Root rows are upserted rather
than deleted, since another entry's supersedes_id
can reference them. Nested rows resolve their
parent by natural key, because assigned ids are
per-build. The version stamp is written only when
every change resolved.

Verified against a real range: applying the patch
to the older database reproduces all 270 changed
entries exactly as a full rebuild does.

Fixes #657

Changes

Incremental patch generation

Layer / File(s) Summary
SQLite schema reflection
scripts/generate-patch.ts, scripts/__tests__/generate-patch.test.ts
The generator reflects writable tables, relationships, FTS tables, dependency depth, and natural-key mappings from SQLite schemas. Tests cover nested tables, composite keys, cross-collection ownership, and FTS exclusions.
Generic row rewrite statements
scripts/generate-patch.ts, scripts/__tests__/generate-patch.test.ts
The generator deletes descendants in dependency order, upserts roots, rewrites child and FTS rows, and resolves nested parent references. Integration tests cover differing assigned IDs, unrelated rows, and inbound references.
Patch validation and CLI orchestration
scripts/generate-patch.ts, CLAUDE.md
Patch generation accepts a database path, validates changed entries and database rows, copies schema metadata, avoids writing unresolved patches, and supports --db and --skip-build. The documentation describes these invariants.

Hardware manual links

Layer / File(s) Summary
Update effector manual resources
data/hardware/pioneer-dj-efx-1000.yaml, data/hardware/pioneer-dj-efx-500-r.yaml, data/hardware/pioneer-dj-efx-500.yaml, data/hardware/pioneer-dj-rmx-1000-m.yaml, data/hardware/pioneer-dj-rmx-1000-w.yaml, data/hardware/pioneer-dj-rmx-1000.yaml, data/hardware/pioneer-dj-rmx-500.yaml
Seven Pioneer DJ effector resource entries now point to AlphaTheta instruction manual articles. Applicable resource titles changed from “Specifications” to “Instruction Manual”.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 3ee6c

Generated patches can fail to apply when related content and hardware changes are included together because foreign-key dependencies are not fully respected across collections. The reflection edge cases also need owner awareness before relying on the generator for future schema changes.

Detect assigned primary keys from table structure. isAssignedPk fails for quoted inline and single-column table-level INTEGER primary keys. writableColumns then includes the assigned key, and insertStatements writes the build-generated ID into the target database.

Choose a deterministic natural key for nested parents.

reflectCollection uses the first unique index returned by PRAGMA index_list. SQLite does not guarantee that result order, so lookup SQL may change when a parent has multiple unique indexes. Select a deterministic unique index and reject indexes with nullable key columns. If a copied key contains NULL, insertStatements emits "column" = NULL, so the parent subquery returns no id and the child insert fails or writes a null foreign key. The current hardware_variants key (hardware_id, slug) is non-null.

Comment thread scripts/generate-patch.ts Outdated
CodeRabbit review on #672. None is a live bug
against the current schema; all three are traps
the reflection would spring on a future one.

Assigned primary keys are now read from
table_info rather than matched in the CREATE
statement, where a quoted column name read as
real data and the build's own id would be written
into the target database.

A nested row's natural key is chosen
deterministically (PRAGMA index_list promises no
order) and must be NOT NULL, since a null becomes
`"col" = NULL` in the lookup and matches nothing.

Nesting deeper than two levels is refused rather
than silently omitted: the statements resolve one
level, so a depth-3 child would be looked up
through an integer key compared against the
root's text id.

Adds a changeset, missing because the PR touches
data/*.yaml.
