docs: handoff 75 — D3 package managers complete (Scoop/Homebrew/winget)
Covers the session that finished the D3 rollout: install.ps1 Windows 5.1
fixes, Scoop + Homebrew wiring and validation, the Homebrew-403 presigned-URL
saga fixed via a server-side Caddy HEAD rule, and the winget job + komac
bootstrap (PR #391335). Records the infra created off-repo (Caddy rule, the
lazyeval Gitea/GitHub bots + tokens), the gotchas, and the parked signing
tracks.

# Session handoff — 2026-06-21 (75)
Continues from handoff-74 (v0.2.0 live on crates.io). This session **finished
the D3 package-manager rollout** — Scoop, Homebrew, and winget — plus the
Windows `install.ps1` fixes, and included a deep **presigned-URL / Homebrew**
debugging saga that's fixed by a server-side Caddy rule. Five commits; one
new ADR amendment arc (ADR-0056 Amendments 24).
## §1. State
**Branch `main`.** **No crate (Rust) code changed this session** — only
`.gitea/workflows/`, `scripts/`, and `docs/`. So the `cargo test` baseline
from handoff-74 (**2509 pass / 0 fail / 1 ignored**, clippy + `fmt --check`
clean) stands unchanged by construction; not re-run (nothing in the build
graph moved). New coverage this session is **`scripts/test-package-renders.sh`**
(shellcheck-clean, green), now gated on every push by a new **`ci.yaml`
`manifests` job** (bash + node; ruby-absent in CI degrades gracefully).
**Commits this session** (`cabc813``0208c67`; the workflow-bearing ones were
pushed, since the live `publish` dispatches + raw-URL installs the user tested
needed them on `main`):
- `42b40bc` install.ps1 → Windows PowerShell 5.1 compat
- `c0531aa` install.ps1 → immediate-use PATH + honest messaging
- `6d54c1e` Scoop + Homebrew jobs (D3 §3b/§3c)
- `6bb2288` Scoop/Homebrew validated + Caddy fix recorded (Amendment 3)
- `0208c67` winget job via komac (D3 §3d, Amendment 4)
**External / infra state created this session (NOT all in the repo):**
- **Caddy Tier-A HEAD rule on the Gitea server** — *load-bearing for Homebrew*,
lives in the Gitea edge config, **not** this repo (see §4). If lost on a
server rebuild, brew 403s again.
- **Gitea:** `lazyeval` org with repos **`scoop-bucket`** + **`homebrew-tap`**;
**`lazyeval-ci`** Gitea bot user (org team, Write to those repos);
**`LAZYEVAL_PKG_TOKEN`** secret on `oli/rdbms-playground`.
- **GitHub:** **`lazyeval-ci`** bot account; classic `public_repo` PAT →
**`WINGET_GITHUB_TOKEN`** secret on `oli/rdbms-playground`; fork
**`lazyeval-ci/winget-pkgs`**.
- **winget bootstrap PR [#391335](https://github.com/microsoft/winget-pkgs/pull/391335)**
submitted, in Microsoft review.
- **komac 2.16.0** installed locally at `~/.local/bin/komac`.
## §2. D3 — the package-manager set (the session's throughline)
| Channel | State |
| --- | --- |
| crates.io / `cargo binstall` | **live** (handoff-74) |
| `install.sh` / `install.ps1` | **live** — PS1 validated on ARM Windows 11 (5.1 + 7.6) |
| Scoop (`lazyeval/scoop-bucket`) | **live + validated** (install + run) |
| Homebrew (`lazyeval/homebrew-tap`) | **live + validated** — needs the Caddy rule (§4) |
| winget (`LazyEvaluation.RdbmsPlayground`) | **wired**; PR #391335 awaiting Microsoft merge |
How Scoop/Homebrew/winget are wired: sibling jobs in
`.gitea/workflows/publish.yaml` (manual `workflow_dispatch`, `tag` input),
each idempotent + independent. Scoop/Homebrew render **dependency-free bash**
manifests (`scripts/render-{scoop-manifest,homebrew-formula}.sh`) from the
release `.sha256` sidecars and push to the org repos via `LAZYEVAL_PKG_TOKEN`.
winget runs `komac update --submit` to PR `microsoft/winget-pkgs`, guarded
against duplicate PRs. ADR-0056 **Amendments 24** carry the full design.
## §3. The Homebrew 403 saga + Caddy fix (don't lose this)
Homebrew `brew install` 403'd while every other tool worked. Root cause,
reproduced: Gitea (≥1.25; here 1.26.2) **303-redirects release downloads to a
method-bound AWS-SigV4 presigned S3 URL** (OVH), signed for the *incoming*
request's HTTP verb. Homebrew **resolves with a HEAD, captures the returned
HEAD-signed URL, then runs the download GET against it** → GET-on-a-HEAD-signed
URL → 403. (`GET on HEAD-resolved = 403`, `HEAD on HEAD-resolved = 200`,
`GET on GET-resolved = 200`.) GET-only tools (install.sh/ps1, binstall, curl)
are unaffected. This is a **Homebrew defect** (reusing an ephemeral
method-scoped credential as a durable locator); Gitea's per-request signing is
correct, and SigV4 *cannot* sign one URL for two verbs. `SERVE_DIRECT=false`
would fix it but was **declined** (don't reshape storage for one client).
**Fix (deployed, "Tier A"):** a Caddy rule answering **HEAD on
`…/releases/download/…` directly** (200, no redirect, no body) so brew's
resolve records the *original* URL and its download GET redirects fresh →
GET-signed → 200. GET untouched; a HEAD carries no payload so nothing can
break (a HEAD-probing download manager at most loses a progress-bar size).
Reference Caddyfile is in **ADR-0056 Amendment 3**.
## §4. Immediate next steps
1. **winget PR #391335:** watch validation — the one likely speed bump is an
**AV/SmartScreen manual-review label** (unsigned binary); usually clears.
Once a moderator merges, winget is live.
2. **Post-merge check (Windows):** `winget install LazyEvaluation.RdbmsPlayground`,
confirm the command is **`rdbms-playground`** (it is — a direct single-exe
portable takes its PATH alias from `Commands[0]`, which komac set; see §5).
3. After merge, future releases are hands-off: the CI `winget` job's
`komac update` carries each version (alias inherited from the merged
manifest). The release ritual is unchanged from ADR-0054, with the
`publish` dispatch now also doing Scoop/Homebrew/winget.
## §5. Gotchas learned (don't relearn the hard way)
- **The Caddy HEAD rule is server-side, not in this repo.** Homebrew (and any
HEAD-then-GET client) depends on it. Record/back it up.
- **GitHub tokens:** komac needs a **classic `public_repo`** PAT — **fine-grained
tokens can't open the cross-fork PR** (komac #310: the PR is created on the
*target* repo you don't administer, which the fine-grained model can't
express). A classic token can't be repo-scoped, so it lives on a **dedicated
bot** (`lazyeval-ci`) to bound the blast radius.
- **komac fork must pre-exist:** `komac new` auto-fork *races* on winget-pkgs
(huge repo) → *"Could not resolve to a Repository 'lazyeval-ci/winget-pkgs'"*.
Fork manually first (`gh repo fork microsoft/winget-pkgs --clone=false`),
wait, then re-run. Pre-fill `komac new` flags to skip the long interactive
prompt parade.
- **Direct portable alias = `Commands[0]`, NOT `PortableCommandAlias`.** The
latter is **archive/nested-portable-only**; adding it to a bare-exe portable
is wrong (komac correctly omits it). The "Commands" prompt → `rdbms-playground`
is the on-PATH command. Verified vs winget-cli logic + the 1.6.0 schema.
- **install.ps1 / Windows PowerShell 5.1** (the in-box shell — PS7 is opt-in):
arch via `PROCESSOR_ARCHITECTURE` env (not `RuntimeInformation::OSArchitecture`,
which is absent under 5.1's .NET-Framework facade + StrictMode); force TLS 1.2;
`-UseBasicParsing`. Also update `$env:Path` in-session (the persisted User PATH
only reaches *new* processes; "restart your shell" was wrong — sign-out/in or
the in-session update).
- **Gitea release downloads go through OVH S3 presigned URLs** — method-bound,
300 s expiry. Never assume HEAD-resolve-then-GET works against them.
## §6. Parked / deferred (user decisions)
- **macOS Developer-ID signing + notarization** — pending the Apple account →
Organization conversion. Ad-hoc signing covers all package-manager paths
(brew-installed binary *runs* on Apple Silicon); Developer-ID only matters for
browser-download Gatekeeper trust.
- **Windows code signing (Trusted Signing)** — not required to *ship* winget
(portable; only MSIX needs signing). Unsigned can earn an AV/SmartScreen
manual-review label + a user-run warning. **Lazy Evaluation Ltd (since 2012)
clears Trusted Signing's 3-year-org bar** when the user wants to remove the
warning (individual onboarding is currently paused; org path is open).
- **Release notes / CHANGELOG** — raised this session, not done. If wanted:
a `CHANGELOG.md` and/or populated Gitea release bodies, then the CI `winget`
job can pass komac `--release-notes-url …/releases/tag/$TAG`.
## §7. How to take over
1. Read handoffs 73 → 74 → 75, `CLAUDE.md`, `docs/requirements.md` (D1/D3),
and **ADR-0056 (esp. Amendments 14)** + the GA plan
`docs/plans/20260616-public-availability.md`.
2. Workflow unchanged: phased, test-first, `/runda` + DA before commits, ADR
amendment + README index-upkeep for decided-area changes, confirm commit
messages, never push.
3. If `cargo test` is needed, the baseline is **2509 / 1 ignored** (handoff-74).
4. Consider a `cargo sweep` at this milestone (`target/` grows).
