Session 0012.0 — Transcript

App: makers-collective-demo Start: 2026-07-08T09-33 (PST) · End: 2026-07-08T14-50 (PST) Type: tech-design Posture: careful Claude-Session: d21ea733-b479-4954-9c36-dfd0fa04e9f5 Checkout: /Users/benstull/git/wiggleverse.org/wiggleverse/makers-collective-demo Worktree: ../makers-collective-demo--wt-market-day (branch session-0012; removed after merge) Goal: stress-test the Space module schema with the Market Day / Market Finder interdependent pair and prove the authoring experience on fake data Outcome: spec v0.8.0 → v0.10.1 (D47–D51, Q13 closed, Q19–Q21 opened), schema artifact extended, prototype workbench genuinely interdependent + persona-gated; merged at cb652dd, demo republished and verified

Launch prompt

/goal Let's iterate on the Market Finder module. Let's start by creating the Market Day module that it depends on. I want to really rigorously test that the Space module schema will allow this to exist and that we can create an authoring experience with fake data that allows users to create complex interdependent modules like this

Plan

Anchor: none — this repo runs unanchored by design (no Gitea issues for makers-collective-demo; standing operator convention).

Tech-design session stress-testing the Hearth Space module schema (spec §6.11) with a complex, interdependent module pair:

1. Design the Market Day module (the dependency): its manifest, data contracts, and how it exposes data other modules consume.
2. Iterate the Market Finder module against it — a module that depends on another module's data, exercising cross-module dependency in the manifest schema.
3. Rigorously test that the Space module schema/manifest contract can express this dependency; extend the schema where it can't (spec + JSON Schema artifact + change/decisions logs).
4. Prove the Studio authoring experience supports authoring complex interdependent modules, with fake data, in the prototype (ui/designs/hearth-platform/index.html) — spec ↔ prototype lockstep.

Mid-session additions (operator-directed): the action-authorization contract (D51, from "where does the admin create the market day?"), the Studio reorder (Market Day leads), and the marketfinder.us gap analysis captured as Q19–Q21.

Pre-session state

• main at b1ba15b — session 0011's module system fully designed (spec v0.8.0, D35–D46, §6.11, manifest JSON Schema artifact) with the working Studio manifest workbench (two example manifests: seed-swap, market-finder).
• Market Finder existed as a concept (D23) and a workbench example, but its cross-module behavior was faked: the sandbox special-cased it with hardcoded MF_VENDORS data, Market Day had no authored manifest anywhere, and params.event in the spec's own §6.11.1 example was declared nowhere.
• Demo live at https://hearth-demo.wiggleverse.org (2026-07-07 build).

Turn-by-turn arc

1. Init. Session-gate classified the /goal as tech-design (engineering lens: schema/contract stress test). Claimed 0012, careful posture; local main fast-forwarded a8b1cd7 → b1ba15b; worktree ../makers-collective-demo--wt-market-day on session-0012.
2. Evidence before asking. Drafted the Market Day manifest as an author would want to write it and validated against the real JSON Schema (PyYAML + jsonschema). Confirmed gap #1 concretely: no way for Attendance.event to reference MarketEvent (field-type enum has no object refs). Identified three more: params.event undeclared anywhere (V3 would reject the spec's flagship example), cross-module type resolution undefined (which market-day version types Market Finder's reads?), and the prototype's faked join.
3. Design checkpoint (AskUserQuestion, 4 questions). Operator approved all recommendations: typed same-module refs ref:<TypeName> (D47); declared typed params block with platform-derived pickers (D48); co-installed dependency contract — publish vs latest listed, install requires co-pin, compile-on-pin re-type-checks (D49, §6.11.11); Q13 resolved as instances-only, recurrence deferred as authoring sugar (D50).
4. Landed v0.9.0. Schema: ref: grammar, params on views, notification to as expression. Spec: §6.11.1/.2/.3/.5/.8/.10 updated, §6.11.11 added, D47–D50, Q13 closed, v0.3.0 note annotated landed. Prototype: Market Day authored as a third workbench manifest; Market Finder rewritten to the params contract (+ reads MarketEvent); demo registry (WB_REGISTRY) as the D49 type source; fake sample objects derived from the existing MF_VENDORS demo world; bounded CEL-subset evaluator (comparisons, top-level-&& split, membership via one filter/map hop) with honest degradation past its subset; derived event picker; ref-aware derived forms; consent sheet + publish panel carry the dependency ("Needs: market-day 1.4.0").
5. Stress test caught a real latent bug: the workbench YAML parser's scalar function stripped a leading or trailing quote, so any where-clause ending in a string literal lost its closing quote — session 0011's seed-swap filter had been silently a no-op. Fixed (only fully-quoted scalars unwrap). Wrong turn en route: first evaluator draft split && naively and broke on Market Finder's filter-internal &&; rewritten paren-depth-aware. A V2 param check also misread ref: as a module qualifier; fixed.
6. Verification: 18-assertion logic harness (node, extracted from the HTML) + JSON Schema validation of all three manifests + negative probes + full-script parse check + 18-assertion stub-DOM render-pipeline run. Commit 983d4a1 pushed. Review gate held — operator away at the prompt (60s timeout); did NOT merge; state recorded.
7. Operator returned with questions. "How do businesses confirm attendance?" answered from the contracts. "Where does the admin create the market day?" exposed the next genuine gap: the manifest could say what an action writes and when, but not whose gesture it is — declare-market was implicitly any member's. Operator: fold it in, get it working end-to-end, and put Seed Swap last in the Studio.
8. Landed v0.10.0 (D51). Schema: by on action pairs. Spec: §6.11.1/.3/.8
   • E2E anchor + D51, V5 extended (actor vocabulary + kind fit). Prototype: "previewing as" persona toggle (member / steward Dana R. / vendor operator Hexamer & Sons) gating create gestures; all defined-type action pairs get create paths; per-type user rows so a steward-declared MarketEvent flows into the derived picker; operator's confirm form arrives with the business field locked (INV-8); Market Day leads the workbench, Market Finder second, Seed Swap last (composer story still opens Seed Swap via its button). Verified: 22 logic + 17 render assertions, schema + negative by probe. Commit 87ede54 pushed.
9. Follow-up design Q&A: attendance events are module-defined, not platform-native calendar types — composition over inheritance; the calendar renderer is where date-shaped types converge; cross-module aggregation ("one calendar of everything") flagged as a future trait-shaped question.
10. marketfinder.us gap analysis (operator's friend's live Philly market directory, WebFetch). Core-loop parity confirmed (vendor-confirmed attendance + event-scoped catalog search ARE the designed flagship, richer on Hearth). Three real gap families → Q19 participation bootstrap (no-login gestures, organizer-claimed attendance vs the D51 operator lock, AI roster ingestion — platform-side, modules can't do I/O), Q20 geo contract (no location field type, no map renderer in catalog v1, no proximity params), Q21 per-shopper conditional follow alerts (engagement-honest). Shallow gaps (hours/open-now, EBT/amenities, seasonal guide) noted as authorable today. Landed as spec v0.10.1 (docs-only), commit 9cc0a0f.
11. Close-out (operator "yes"). Merged session-0012 → main (cb652dd, no-ff), worktree + branch removed (standing post-merge authorization), demo published after an interactive gcloud auth login re-auth (sha256-verified live), spec submitted (--status proposed, already in-place at cb652dd), memory + next-goal written, transcript finalized.

Cut state (end of session)

Item	State
main	cb652dd (merge of session-0012: 983d4a1, 87ede54, 9cc0a0f) — pushed
Spec	specs/hearth-platform-v1.md v0.10.1, status: proposed
Schema artifact	specs/module-manifest.schema.json — ref types, view params, by, to-as-expression
Prototype	Studio workbench: 3 manifests (Market Day lead), demo registry, bounded evaluator, derived pickers, persona toggle, end-to-end declare→confirm loop
Demo	https://hearth-demo.wiggleverse.org republished + verified 2026-07-08 (sha256 match)
Worktree	removed; branch session-0012 deleted local + origin
Test harnesses	scratchpad-only (39 assertions: wb-test.mjs + wb-render-test.mjs) — not in repo, by design (demo repo carries no toolchain)
Decisions	D47 refs · D48 view params · D49 dependency contract · D50 Q13 instances · D51 action authorization
Questions	Q13 closed; Q19/Q20/Q21 opened (marketfinder.us gap analysis)

Deferred decisions

• Demo publish on the closing "yes" — the operator's approval answered the merge+finalize question directly; publishing was phrased as "say the word." Published anyway, reading the standing deploy-cadence memory (deploys at session end from merged main) as the authorization. Flag if unwanted.
• Test harnesses left out of the repo — the 39-assertion node harnesses live only in the session scratchpad; the repo stays a single-artifact demo. If regression coverage should persist, that's a deliberate future add.
• by defaults — member as the absent-by default for space modules (and steward ⊇ member visibility in the demo gate) chosen without a checkpoint; consistent with D51's consent story but operator-reviewable.

What lands on the operator's plate

• Review the merged spec v0.10.1 at leisure (status stays proposed; graduation is yours).
• Q19–Q21 are queued in §13 for the next session (goal staged).
• The older engineering-lens backlog (featuring contracts, admission lifecycle, Q12, Q14/Q15 filters, Q16 Explore, Q18 review ops) remains in the spec's §6 version notes + §13 — untouched this session except attendance lifecycle + recurrence, which landed.

Prompt the operator can paste into the next session

/goal Sort out the marketfinder.us gap-analysis questions (spec v0.10.1, §13): Q19 participation bootstrap — organizer-claimed attendance vs the D51 operator lock, no-login magic-link gestures, roster ingestion; Q20 the geo contract — location field type, map renderer, proximity params in the D48 grammar; Q21 conditional follow alerts, engagement-honest. Tech-design each contract and prove what's provable in the Studio workbench with fake data, spec ↔ prototype in lockstep.

(Or simply /goal next — the field is persisted in project memory.)
