From 2104e807ec8aacd10159253f6c34d81a5cd89487 Mon Sep 17 00:00:00 2001 From: Chris Alfano Date: Mon, 18 May 2026 00:34:33 -0400 Subject: [PATCH 1/8] chore(plans): add laddr-import-via-json (planned) Replaces the mysqldump-based laddr-import implementation with a JSON-fetching importer that produces full-snapshot commits on a `legacy-import` branch, then merges into main. Targets codeforphilly.org's `?format=json` endpoints. Plan body covers: branching model, stable legacyId filenames, CLI shape, interactive dev loop, file/module changes (mysqldump path deleted), and the spec amendments to legacy-id-mapping.md that drop MySQL / single-big-commit framing.

Validate during dev; if `?format=json` is missing for any entity (likely candidates: project-memberships, project-buzz, tag-assignments — these may not have user-facing list pages), decide whether to add it on the laddr side (small PHP change), scrape an HTML index, or accept a private export for that table. +- **Pagination.** Large datasets (especially `project-updates`) may not return all rows in one response. Discover laddr's pagination scheme during dev (likely an `offset=` or `?page=` query string) and follow it. +- **Soft-deletes.** laddr's Emergence framework supports versioning; JSON responses may include archived rows. Decide policy during dev (filter at the importer, or carry an `archived` flag forward). +- **Slug-history continuity.** If laddr renames a slug between runs, the importer drops the old `.toml`'s slug field and writes the new one. Slug-history capture is the API's job at runtime (covered in [behaviors/slug-handles.md](../specs/behaviors/slug-handles.md)) — the importer doesn't try to reconstruct it from snapshot diffs. +- **Merge strategy.** Once both branches have moved, the merge may need a deliberate strategy (e.g., always favor `legacy-import` for paths under importer-owned directories). Resolve at the first conflicting merge — over-specifying now is premature. +- **`?format=json` shape stability.** Emergence's JSON output is template-rendered, not a documented API. Schema may shift if anyone tweaks the templates upstream. Zod validation on input surfaces shape changes early. +- **Volume.** A full snapshot could be 10k+ records across 7 sheets; the resulting `git add -A` may be slow but is one-shot per run. No perf engineering needed unless a run takes >5min. + +## Notes + +(filled at closeout) + +## Follow-ups + +(filled at closeout) From dc020864e8fb55c1d35d7919ae60e374b9960f9a Mon Sep 17 00:00:00 2001 From: Chris Alfano Date: Mon, 18 May 2026 00:42:34 -0400 Subject: [PATCH 2/8] docs(specs): re-frame legacy-id-mapping for JSON snapshot importer Drop "single big commit" / MySQL framing.

Consecutive runs diff cleanly to show what changed upstream. Differences from the prior mysqldump implementation: - Reads JSON from the live site, not a SQL dump file. No fixture SQL or mysqldump parser needed. - Memberships and tag-assignments arrive via `?include=Tags,Memberships` on the projects list (and `?include=Tags` on people) — no separate `/project-memberships` or `/tag-assignments` list endpoints exist. - Files on `legacy-import` are keyed by laddr's auto-increment ID (`/.toml`, composite for memberships and tag-assignments) so re-runs overwrite stable paths. - Full-tree replace per run, not per-entity upserts.

With the JSON importer in place, adapt: - cutover-dry-run.ts now wraps importLaddrFromJson in dry-run mode and compares per-sheet imported counts against the laddr server's reported `total` for each list endpoint. Tolerable-diff thresholds carve out known data-quality drops (tags with no resolvable namespace, http-only buzz URLs). - cutover-dry-run.test.ts uses an in-memory fetch mock instead of the SQL fixture (which was deleted with the mysqldump-parser removal). - docs/operations/cutover.md drops `--sql` from every command and rewords the T-3, T-1, and T-0 steps to describe pulling from the live laddr site and committing snapshots on the `legacy-import` branch. - docs/operations/cutover-rollback.md updates the read-only-source line. - specs/architecture.md rewrites the "Data migration" section to describe the snapshot/merge model rather than "one big commit."

Private data (emails, password hashes, newsletter prefs) is handled separately at cutover via the [account-claim flow](behaviors/account-migration.md). ## Authorization model From 02c6f8bde62199d3b245d9bb2d70d254af54ace9 Mon Sep 17 00:00:00 2001 From: Chris Alfano Date: Mon, 18 May 2026 01:59:17 -0400 Subject: [PATCH 6/8] perf(importer): batch existing-id reads via git cat-file --batch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The first cut of the existing-IDs pre-pass called `git show HEAD:` once per importer-owned TOML file. For a typical snapshot (~44k files), that's 44k fork+exec roundtrips which took 7+ minutes to complete on the second run. Replace with a single `git cat-file --batch` subprocess that streams blob contents in one stdin/stdout exchange. Verified against the full 44k-file snapshot — pre-pass now finishes in seconds. Also add a test verifying the "single-record-change" criterion from the plan: importing the same dataset twice with one project's Title flipped produces a commit whose diff is exactly that file.

Synthesized as TagAssignment + ProjectMembership records during translation. The Approach section's 7-endpoint list is therefore aspirational; what shipped is 5 endpoints + 2 includes. +- **Pagination is `limit` + `offset`** in the JSON envelope. First-page `offset` is the literal `false` (laddr's quirky default rendering when no `offset` query param is supplied); subsequent pages use integer `offset`. The fetcher's Zod schema accepts the union. +- **Tag handle JSON-renderer quirk.** Laddr's JSON output sometimes strips the `.` from tag handles (`topicparking` instead of `topic.parking`), but the `Title` field carries the proper form (`topic.Parking`). The translator falls back to splitting on the Title when the Handle has no resolvable namespace. About 33 tags recover this way; about 120 still skip because neither field has the namespace. +- **Idempotence works via UUID carry-forward.** A pre-pass reads every importer-owned `.toml` from the existing branch tip via `git cat-file --batch` and extracts the `id` field. Subsequent translations consult this map so re-runs reuse the same UUID for each file path. Verified end-to-end: a re-run against the live site produces a commit whose diff is exactly the records that changed upstream (in our test: 1 modified Person + 2 newly-created Persons between two runs ~12 minutes apart). +- **`git cat-file --batch` is load-bearing.** The first cut used one `git show HEAD:` call per file, which was 7+ minutes wall-time at 44k files. The batched implementation finishes in seconds. Same pattern recommended for any future scripts touching the snapshot tree wholesale. +- **HTTP-only buzz URLs (~72% drop).** The `ProjectBuzz.url` schema requires `https://`, but most pre-2018 laddr buzz records have `http://` URLs. 81 of 113 records skip on each run. Tracked as issue #56 — possible resolutions are documented there. +- **Tags with no resolvable namespace (~12% drop).** About 120 laddr tags have bare handles (`cocoa`, `aws`, `naloxone`) where neither Handle nor Title carries a namespace. Tracked as #58. +- **PII grep nuance.** `grep -E '@[a-z0-9.-]+\.[a-z]+'` against the imported tree returns ~520 matches, all in user-authored markdown content (person bios + project README/overview fields). These are emails users voluntarily wrote into their own laddr profile/project pages — already publicly displayed on `codeforphilly.org` for years. **No structured PII fields** (`email =`, `passwordHash =`, `emailRefreshedAt =`) appear anywhere in the public repo. The criterion's intent was satisfied; the literal grep pattern is too broad for laddr's freeform-markdown reality. +- **Branch model decision.** The legacy-import branch's filenames are keyed by `legacyId` (`projects/393.toml`) while the runtime spec's gitsheets path templates are slug-based (`projects/${slug}.toml`). The importer uses bare-git operations (write + commit), not gitsheets transact, because the path-template mismatch would otherwise fail gitsheets validation. The legacy-import branch is **parallel history** — runtime data lives on `main`, and the operator's merge from legacy-import into main is responsible for any path-shape translation needed (currently tracked as #59). +- **Author identity.** Every commit on legacy-import is authored as `Code for Philly API ` via explicit `GIT_AUTHOR_*` env vars. The agent's git config is not used, so commits are attributable to the importer itself rather than whoever happened to run it. +- **Push not automated.** The plan's Approach said "5. Push to origin." Pushing the local `legacy-import` branch to the data repo's remote is a deliberate operator step (so a misconfigured run can't pollute the public branch).
