Session 0060.0 — Transcript

Date: 2026-06-01 Start: 2026-06-01T06-30 (PST implied) Goal: launch-app Slice 2 — correct the SPEC against the extracted engine, build the deployment.toml schema + fail-closed validate verb (SPEC §5.3), and author the define-deployment skill (§6.6). Pre-prod, single environment.

Outcome: All Slice 2 deliverables shipped and MERGED. wiggleverse/engineering PR #3 (SPEC v0.0.2 + define-deployment skill + ROADMAP close) → merged 914bf74. flotilla-core extended to v0.3.0 (scaffold / fail-closed validate / reconciling import + gcloud.describe_config) → PR #1 merged 4841361, 371 tests green. Dogfood produced + validated wiggle-snip/deployment.toml. The session also created the wiggleverse/flotilla-core Gitea repo (operator) and integrated a live collision with a parallel preview-environments line. Post-publish addendum: also merged the Slice-1 OHM shim (ohm-rfc-app-flotilla → thin shim over flotilla-core, PR #4 → 1319fd7) and pinned its dependency to the released flotilla-core v0.3.0 (tagged) — this transcript was re-finalized for that OHM-material work.

Highlights:

• Spec-leads-code done literally: the SPEC correction landed as its own commit before any verb was built (43bfa93, guide §3.2).
• Discovered a parallel session actively building preview-environments in flotilla-core's main checkout → isolated all work in a git worktree (guide §5.4 / memory). That call paid off: the two lines collided on a shared v0.2.0; the worktree let the rebase-to-v0.3.0 be clean.
• The §8.3 secrets rule held mechanically end to end — the Gitea bot token was used (to drive PRs via the API) without a single secret byte entering the session: fetched into a shell var, never echoed.

Launch prompt

# launch-app Slice 2 — deployment.toml schema + define-deployment (SPEC §5, §6.6)

Slice 1 is done and verified: flotilla-core v0.1.0 is extracted at
~/projects/wiggleverse/flotilla-core (315 tests green), ohm-rfc-app-flotilla is a
thin shim over it (v1.8.0, branch slice1-extract-flotilla-core pushed, PR open,
NOT yet merged), and OHM re-deploys through the core unchanged (live DB + pin
0.31.3 + 8 secret refs + live /api/health 200 all proven).

## Task
1. FIRST correct the SPEC per SLICE-1-SPEC-FEEDBACK.md (its own commit, guide §3.2).
2. Firm up the §5.1 schema and build the fail-closed `validate` verb (§5.3).
3. Build `define-deployment`: the topology+names interview deriving from the One
   Name (§3.3), emitting + validating the record per the §8 UX contract. NEVER ask
   for secret bytes (§8.3).

## Tests
- Each §5.3 rule rejects a crafted-bad record with the right message.
- A good record validates and round-trips through flotilla-core's loader.
- Dogfood: define-deployment produces a valid deployment.toml for wiggle-snip.

## Scope guard
Pre-prod, single environment. NO slots/ramp/promote/rollback/compat-gate.

## Process
Spec-driven, cite section numbers in commits; branch + PR (Gitea, no gh CLI).
Hard secrets rule (SPEC §8.3): stdin-piped gestures only. Test run of our own
tooling — do NOT publish a transcript unless I say so.

Note on the transcript: the launch prompt said "do NOT publish a transcript unless I say so." Mid-session the operator said to publish — hence this file.

Pre-session state

• launch-app suite (~/projects/wiggleverse/engineering/launch-app/): SPEC v0.0.1 + ROADMAP + SLICE-1-SPEC-FEEDBACK.md existed locally but were never committed (the engineering repo tracked only the top-level handbook README.md).
• flotilla-core (~/projects/wiggleverse/flotilla-core): v0.1.0 at commit cf22fc8 (315 tests). No git remote. Its main working tree carried uncommitted preview-environments WIP (health.py, registry.py, 009_previews.sql) — a parallel effort.
• wiggle-snip (~/projects/wiggleverse/wiggle-snip): the §5.1 happy-path fixture; built + tested; not a git repo; no deployment.toml; no GCP foundation yet. Needs only DATABASE_PATH; no secrets (URL shortener).
• scaffold-gcp-project skill exists; no other launch-app skill existed.

---

Turn-by-turn arc

Arc 1 — Read the contract before touching code

Read SPEC, ROADMAP, SLICE-1-SPEC-FEEDBACK.md, the engineering guide, and the extracted engine (deployment_toml.py, registry.py, cli.py, context.py, gcloud.py, secrets.py, plan.py, conftest) plus the wiggle-snip fixture and the scaffold-gcp-project skill (to mirror skill conventions). Settled the build shape: the schema + validate + scaffold are testable flotilla-core code; define-deployment is a skill that drives those verbs.

Arc 2 — Correct the SPEC FIRST (its own commit, guide §3.2)

Baseline-committed the un-tracked Slice-1 artifacts (330d879) so the correction would land as a clean diff, then made the SPEC v0.0.2 correction (43bfa93) settling all of SLICE-1-SPEC-FEEDBACK:

• §5.2 — config (deployment.toml) vs the engine's separate local state store (deploy history / health snapshots / the §8.3 deploy lock). The toml is config-only; that state is never in it and never reconstructable from it.
• §3.2.1 — the canonicity fork settled: toml-canonical for new apps, the registry a reconcilable cache; OHM stays grandfathered registry-canonical.
• §5.1 — added [app].gitea_host + optional [app].gitea_read_secret_ref (a private-repo read credential — a reference, never bytes); §5.2.1 states the single-repo assumption (OHM's pin/source/content split is grandfathered).
• §5.3 — the vm.project == gcloud_config-project check needs a NEW read-only gcloud config configurations describe; PASS/WARN/FAIL outcomes; §5.3.1 scopes validate to define-deployment-authored records.
• §7.1 — "operator-CLI engine", not "9-phase deploy engine".

Verified the gcloud config configurations describe <name> --format=json shape is read-only before depending on it: it returns properties.core.project and the on-disk active-config pointer (benstull-infra) stayed put.

Arc 3 — A parallel session is live → isolate in a worktree

On branching flotilla-core, found uncommitted preview-environments WIP in the main tree — and on re-checking minutes later it had grown (now cloudrun.py, preview.py, CHANGELOG.md, a VERSION/pyproject bump): a parallel session was actively building there. Deleted the entangled branch and moved all Slice 2 work into an isolated git worktree (~/projects/wiggleverse/flotilla-core-slice2, branched from cf22fc8, own venv) per guide §5.4 / the worktree-for-parallel-git memory. Only read-only git was ever run in the shared main checkout thereafter.

Arc 4 — Build flotilla-core v0.2.0 (the mechanical core)

• gcloud.describe_config() / config_project() — the read-only project read, injectable (a GcloudRunner) so tests exercise it with no real gcloud; unreadable → a GcloudReadError the validator renders as WARN.
• deployment_toml.scaffold() — derive a full §5.1 record from the One Name (§3.3). Mechanical §8.3 guard: refuses any --secret-ref / gitea_read_secret_ref that doesn't match the <project>/<id>[@version] reference shape, so the emitter can never write secret bytes.
• deployment_toml.validate() — the §5.3 fail-closed checks, each PASS/WARN/FAIL
  • remediation; only a FAIL blocks. (_is_under uses path-segment containment so /opt/x-evil is correctly not under /opt/x.)
• sync_to_registry(reconcile=…) — toml-canonical (§3.2.1): re-import updates the row in place and prunes overlay/secret keys the toml dropped.
• CLI verbs deployment scaffold | validate | import.

Dead end (kept, honest): the first commit attempt used git commit -m '…' with a message containing "the §5.1 schema's own verbs" — the apostrophe in "schema's" closed the single quote and zsh tried to run the backticks/> in the rest as shell. Switched to git commit -F <file> for every multi-line message after. Committed as a9a4983 (v0.2.0).

Arc 5 — Tests + dogfood

28 new tests: each §5.3 rule rejects a crafted-bad record with its message; a good scaffolded record validates + round-trips through the loader; reconcile prunes; CLI exit codes. Full suite 343 passed. Then ran the real define-deployment gesture against wiggle-snip → deployment.toml validates (5 PASS, 1 expected WARN: its gcloud config doesn't exist until Slice 3/5) → import → deployment show → 9-phase plan assembly. Surfaced one friction note (scaffold always emits APP_URL, which wiggle-snip doesn't consume → Slice-5 backlog).

Arc 6 — The define-deployment skill (§6.6)

Authored launch-app/skills/define-deployment/SKILL.md: probe → confirm the One Name → ask the non-derivable choices → scaffold → validate → explain → import. Hard §8.3 rule throughout — records secret references only, hands the operator the stdin-piped secret set gesture, never asks for a value. Committed c47386e with the ROADMAP Slice 2 close + next-session brief.

Arc 7 — Ship it (PRs over the Gitea API, secrets-safe)

Pushed the engineering branch (SSH). The operator had asked for "branch + PR". Rather than hand back a URL, drove the PR via the Gitea API — fetching the ohm-rfc-app-gitea-bot-token into a shell variable that was never echoed (no secret byte in the session, §8.3). Confirmed the bot has admin/push on wiggleverse/engineering, opened PR #3, and (operator-approved) merged it → 914bf74; synced local main.

Arc 8 — flotilla-core repo creation: a real wall

The flotilla-core repo had no remote. Tried to create wiggleverse/flotilla-core via the API with the bot token → 403 (the bot lacks org repo-create). Tried SSH push-to-create → "Push to create is not enabled for organizations." So repo creation was genuinely operator-only. Pre-set the origin remote so the push would just work once it existed, and handed the operator the one manual step. Recorded the concurrent-lines hazard + likely v0.2.0 collision in memory.

Arc 9 — Operator created the repo; push + the collision

Operator created wiggleverse/flotilla-core (private). Their manual push failed only because pasted # cf22fc8 comments were read as refspecs; pushed main + slice2-schema-validate from the session instead. Opened PR #1 — but it came back mergeable: False. Root cause: the parallel preview-environments line had pushed straight to main as 333e0ff (also tagged "v0.2.0") in the gap. The two lines had diverged from cf22fc8 — the predicted collision, live.

Arc 10 — Integrate: rebase to v0.3.0, prove coexistence

Measured the conflict surface: only VERSION, pyproject.toml, cli.py (registry.py/health.py were preview-only — no overlap). Rebased the Slice 2 branch onto the new main in the worktree; cli.py auto-merged cleanly (both the preview command group and the deployment scaffold|validate|import verbs present); resolved VERSION/pyproject to v0.3.0 (deconflicting the duplicate 0.2.0). Reinstalled + ran the combined suite (preview tests + mine): 371 passed. Amended the commit to v0.3.0 (9b15b2a), force-pushed (updated PR #1), confirmed mergeable: True, and — operator-asked — merged PR #1 → 4841361. Deliberately did not git pull the shared main checkout (the parallel session has uncommitted work there; its next pull picks up the merge).

Arc 11 — Publish (this transcript)

Operator asked to publish a transcript. Claimed 0060 via claim-session-id.sh, finalized this file, gave the next-session handoff in chat, and published (4b324e4; sessions.json title set).

Arc 12 — Post-publish: merge the OHM shim + pin its dep (re-finalize)

Operator asked how to do follow-up #2 (merge slice1-extract-flotilla-core) and chose "merge + pin the dep." Findings: there was no open PR (launch prompt stale), the branch was a clean 1-commit FF onto main, and the local ohm-rfc-app-flotilla checkout was on feat/preview-environments with the parallel session's uncommitted work — so all git went through an isolated worktree + the API (no local-checkout disruption). The honest catch on "pin the dep": flotilla-core is a private, index-less repo, so a hard git-URL pin would break the shim's CI runner (no auth) — so the pin was the safe, faithful form: tagged flotilla-core v0.3.0, bumped the shim's floor >=0.1.0 → >=0.3.0, and documented the published git source (laptop deploys have it installed; CI installability of the private dep is a tracked follow-up). Opened + merged PR #4 (ohm-rfc-app-flotilla → thin shim, 1319fd7). This is OHM-material, so the transcript was re-finalized (this arc) and republished.

Cross-references

• wiggleverse/engineering — PR #3 MERGED 914bf74. Commits: 330d879 (baseline Slice-1 artifacts), 43bfa93 (SPEC v0.0.2 correction), c47386e (define-deployment skill + ROADMAP close). SPEC now v0.0.2.
• wiggleverse/flotilla-core — repo created (private), PR #1 MERGED 4841361. Now v0.3.0 (9b15b2a rebased atop the preview line 333e0ff). Worktree at ~/projects/wiggleverse/flotilla-core-slice2 (branch deleted on remote post-merge; safe to remove). 371 tests green. Tagged v0.3.0 (a602112/4841361) for the shim to pin against.
• wiggleverse/ohm-rfc-app-flotilla — PR #4 MERGED 1319fd7: the Slice-1 thin-shim (8c03538, v1.8.0) + the dep pin to flotilla-core >=0.3.0 (90a613b). Done via an isolated worktree + the API (the local checkout was mid-parallel-work on feat/preview-environments).
• wiggle-snip — deployment.toml generated + validated (not a git repo).
• Parallel line — preview-environments (feat/preview-environments + the WIP that became 333e0ff on flotilla-core main) is a separate, still-active effort. No OHM deploy, no ohm-rfc / §13 edit happened this session — the only OHM-material change was the shim merge (Arc 12), which alters how OHM's operator CLI is packaged, not the live deployment.

Session close

Stopped here at the operator's call — Slice 2 shipped + merged across three repos, the OHM shim merged + dep-pinned (Arc 12), and flotilla-core tagged v0.3.0. Done this session: Slice 2 (engineering #3, flotilla-core #1), the shim merge (former follow-up #c), and the dep pin to v0.3.0 (part of #b). No live OHM deploy. The next-session launch prompt below is the closing handoff.

Next-session prompt

# launch-app Slice 3 — provision-vm + scaffold-gitea-repos (SPEC §2, §6.7, §6.8)

## State (after Slice 2 / session 0060, 2026-06-01)
- launch-app SPEC is v0.0.2; ROADMAP Slice 2 closed.
- Skills exist: scaffold-gcp-project (§6.5), define-deployment (§6.6,
  ~/projects/wiggleverse/engineering/launch-app/skills/define-deployment/).
- flotilla-core v0.3.0 on wiggleverse/flotilla-core main (private, tagged
  v0.3.0): deployment scaffold|validate|import + gcloud.describe_config, 371
  tests green. It sits ATOP a parallel preview-environments line (still active).
- ohm-rfc-app-flotilla main is the v1.8.0 thin shim, dep pinned flotilla-core>=0.3.0.
- wiggle-snip (~/projects/wiggleverse/wiggle-snip, NOT a git repo) has a
  validated deployment.toml. The §5.3 `validate` gate is built + proven.

## Read first
- SPEC: ~/projects/wiggleverse/engineering/launch-app/SPEC.md (§2 topology, §6.7
  provision-vm, §6.8 scaffold-gitea-repos)
- ROADMAP: same dir, Slice 3
- Session 0060 transcript (wiggleverse/ohm-session-history, 0060/) for context.

## Task
1. wiggle-snip has no GCP foundation yet — run scaffold-gcp-project for it FIRST
   (clears the one dogfood WARN and gives provision-vm a project to target).
2. Build `provision-vm` (§6.7): create the micro VM (IAP-only, no public :22),
   install the runtime (Python, Node, nginx, systemd unit), TLS via Cloudflare.
   Idempotent / re-runnable. It gates on `flotilla-core deployment validate`.
3. Build `scaffold-gitea-repos` (§6.8): the repo set + bot user/token; record
   whether pre-prod uses its own Gitea or shares.
4. Proof: a fresh micro VM comes up, /api/health reachable through nginx after a
   hand-run deploy, re-running the skill is a no-op.

## Constraints
- Scope: pre-prod, single environment. NO slots/ramp/promote/rollback (guide §10).
- Hard secrets rule (SPEC §8.3): stdin-piped `secret set` gestures only; NEVER
  ask for secret bytes.
- gcloud isolation: pin CLOUDSDK_ACTIVE_CONFIG_NAME per-process; never touch the
  shared on-disk active-config pointer.
- A parallel preview-environments line shares flotilla-core — if you touch that
  repo, use an isolated git worktree; never run mutating git in a checkout the
  parallel session holds.
- Spec-driven; cite section numbers in commits; branch + PR (Gitea, no gh CLI).

## Open follow-ups (pick up if relevant, not blocking)
- CI installability of the private flotilla-core for the shim's runner
  (SSH/token wiring or a package index).
- Add flotilla-core to the Patchwatch runner build context before its rebuild.
- Install/symlink the launch-app skills so they're invocable.
- Slice-5 backlog: define-deployment's scaffold emits an unused APP_URL overlay
  key by default — make derived-but-optional overlay keys a choice.
