Sign-in, document ownership, and sample content — live

Magic-link sign-in via rastrillo/auth, documents owned by people, six
sample documents, and the app deployed at https://docs.bds.oncarlos.com.

Spec §8.1 is reframed: an instance signing people in itself is REQUIRED
by factor VII, not merely acceptable. Self-hosting is a right, so the
standalone path cannot be a degraded tier.

Document text still exists only as replayed Yjs updates through
WebAssembly. There is no content column; the seed updates are honest
output of real yjs with a pinned client id, byte-identical across runs.

Two defects found late are worth recording, because both were certified
correct by something green before they were found.

ApplyUpdate scoped the wrong write. The updated_at bump carried an owner
predicate; the doc_updates INSERT never did. A gorm UPDATE matching zero
rows is not an error, so the method returned nil while a forged OwnerID
wrote a whole document into someone else's. Three things agreed and all
three were wrong: a comment claiming it had closed "the one write in this
file that skipped the seam" (there were two), a test NAMED as proving the
write was refused that asserted only a timestamp, and a verification note
that read the line it was pointed at rather than the operation. Ownership
is now re-derived from the database before anything is replayed or
written — a *Document is a value a caller can construct freely, a row is
not. Latent, not exploited: only Seed called it, with a correct owner.

Sign-in was an open relay. rastrillo/auth consults Config.Authorize at
admission (handlers.go:131, after the link is clicked) and never in
Begin. Ours was nil, and nil admits everybody, so any stranger could have
had this instance's SES identity mail them a link that worked — a session
and a document space, on an app whose premise is one instance per team.
Found by the CARLOS Sheets session on their own deployment; their
diagnosis generalises: every unit test passed because they all tested
admission and none tested delivery. Now gated before Begin, with
byte-identical refusals so the endpoint cannot be used to probe which
addresses exist, and verified live against SES's own send counter rather
than our test suite — the counter is an oracle outside our code, which is
exactly what the blind spot required.

An empty allowlist refuses at startup outside development rather than
admitting nobody: the security fix and the silent-misconfiguration mode
are the same mechanism, since an instance admitting nobody boots looking
healthy, answering its ordinary 303 ?sent=1 on every submission because
the byte-identical refusal is working as designed.

The recurring shape across this branch was a check that reports success
while measuring something adjacent to the question: a gate test that
re-implemented the gate and compared it to itself; carlos ship --target,
which declares an architecture without verifying it, shipping an amd64
ELF labelled linux-arm64 that promoted cleanly and then failed to start
thirty times; an allowlist tested at admission while the hole was at
send. rastrillo.BuildVersion defaults to the literal "dev" unless stamped
via ldflags, which would have made the process-level deploy check pass
while distinguishing nothing.

+## Real per-person sign-in (Task 1, extended in a later fix round)
+
+Every document route — `GET /`, `POST /documents`, `GET /d/{sqid}` — sits
+behind rastrillo/auth's `RequireSession` and is unreachable without a real
+session (`internal/docs/auth.go`). Sign-in is a magic link: `POST /signin`
+emails (or, in development, logs) a single-use link; following it
+(`GET /auth/verify`) sets a real session cookie; `POST /signout` (linked
+from both `list.html` and `show.html`'s page headers) really revokes it,
+not just clearing the cookie client-side. No passkey second factor is
+wired, on purpose — spec §8.1's ruling: `passkey.Config.Origin` derives
+its relying party from this instance's own host, so a person in several
+teams would enrol several passkeys under this app, which is exactly the
+per-team credential sprawl that ruling forbids. A magic link enrols no
+credential, so it violates nothing.
+
+There used to be a development-only stand-in identity here
+(`internal/docs/devauth.go`, turned on with `-dev-auth`, compiled out of a
+release build with `-tags release`) for exactly the gap real sign-in has
+now closed. It had zero readers the moment `RequireSession` started
+guarding every route unconditionally — no handler ever consulted it — and
+was deleted in a fix round on Task 1 rather than left as dead code and an
+unreachable trap for whoever next assumed `-dev-auth` still did something.
+The `release` build tag it was the only user of is gone with it; there is
+no longer a release/non-release distinction anywhere in this app.
+
+`Config.Env` still exists (`"development"` or `"production"`), but it now
+governs exactly one thing, independent of any identity flag: whether
+`InstanceKey` and `Mailer` (`internal/docs/auth.go`) may default — an
+empty `$DOCS_INSTANCE_KEY` or unconfigured mail is fine only in
+development (a fixed dev key, and magic links logged instead of mailed,
+clearly marked); anywhere else it is a startup refusal, the same
+fail-closed shape `Origin` already used. `cmd/docs/main.go`'s `-env` flag
+sets it; `$DOCS_ENV` is consulted too but can never select
+`"development"` on its own (fix round 2 on Task 1 — platform instance
+config *is* environment variables, so a bare `$DOCS_ENV=development`
+sitting beside `$DOCS_ORIGIN`/`$DOCS_INSTANCE_KEY`/`$DOCS_SMTP_*` would
+be a production-reachable path to the public dev `InstanceKey` and to
+every magic link, token included, landing in the instance's own log —
+see `chooseEnv`'s own doc comment). The default, with no flag and no
+env var (or with `$DOCS_ENV=development` and no flag), is
+`"production"` — `"development"` always takes an explicit `-env`
+flag, never a silent fallback.
+
+### Sign-in allowlist (Task 4 security fix, pre-launch)
+
+Real sign-in above closed "who can get a session" but left a separate
+hole open: `rastrillo/auth`'s `Config.Authorize` — the admission gate —
+is consulted only in its own callback handler, after `POST /signin`
+(`Begin`) has already emailed the link. With `Authorize` left `nil` (as
+it was through Task 3), that meant anyone who could reach the instance
+could POST any address and get a working sign-in link mailed to it —
+an open relay on our own SES sending identity, and unrestricted account
+creation on an app whose whole premise is instance-per-team. Found by
+the CARLOS Sheets session on their own deployed instance; every existing
+test passed because they all tested admission, none tested delivery.
+
+The fix is `$DOCS_ALLOWED_ADDRESSES` (`docs.Config.AllowedAddresses`,
+`internal/docs/auth.go`): a comma-separated, case/whitespace-insensitive
+allowlist, wired to *two* places — `rauth.Config.Authorize` (admission,
+belt-and-suspenders) and `gateBegin`, a wrapper mounted in front of
+`rauth.Auth.Begin` on `POST /signin` itself, which is the part that
+actually matters, since it is what stops the mail. A non-permitted
+address gets exactly the same `303 ?sent=1` response a permitted one
+gets — anything else would turn the endpoint into a membership oracle.
+Empty is allowed only in development (admits everyone, so `TestSignIn`
+and `run-dev.sh` need no setup); anywhere else it is a startup refusal,
+the same fail-closed shape `Origin`/`InstanceKey`/`Mailer` already use,
+chosen over silently admitting nobody because a silently-empty allowlist
+would boot looking identical to a working instance.
## Running it locally
-`./scripts/run-dev.sh` builds and runs the app in one command: the
-development-only identity on (`-dev-auth`), a fixed port
-(`localhost:8099`, override with `$DOCS_DEV_PORT`), and a scratch SQLite
-database that starts empty every run. It prints the URL to open.
-
-`-dev-auth` only exists in an ordinary build. `cmd/docs/devauth_flag_release.go`

-observe it — a release binary has no code path that can turn the
-development-only identity on at all, not just a runtime check that refuses
-once it is (`internal/docs/devauth.go`'s `guardDevAuth`, which still runs
-either way, for anything else that might one day set `Config.DevAuth`).

+# Sign-in, and documents worth looking at — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Real per-person sign-in at the instance, so Docs can go live on a public URL — and sample documents with enough content that the reading view is worth looking at.
+
+**Architecture:** rastrillo's `auth` plugin: magic link, auto-upgrading to keymail when an address resolves to a claimed inbox. Documents become owned, and every route requires a signed-in person. Seed content is real prose applied as Yjs updates through the CRDT, not rows in a table.
+
+**Tech Stack:** Go 1.26, rastrillo `v0.22.0` (`auth`, `sessions`, `csrf`, `scope`), `internal/core` (wazero + Rust CRDT), SQLite.
+
+**Spec:** `docs/superpowers/specs/2026-08-30-docs-design.md` — §8.1 (the two deployment shapes), §8.2 (sharing), §4.2 (the 404-not-403 contract), §6.2 (where zero-JS stops).
+
+## Why this plan exists
+
+Paul asked for Docs live at `console.carloku.com/a/bds/apps/docs`. It cannot go on a public URL as it stands: no route requires sign-in, so it is a public read-and-write documents endpoint.
+
+The home would solve it and is weeks away — verified, not assumed: `oficina/home` is a skeleton that boots and serves one page saying it is not built. Nothing about assertions exists anywhere.
+
+**But §8.1 was reframed on 2026-08-31 and this is no longer a stopgap.** A single instance signs people in itself; the home is what a *suite* adds. So this plan builds the single-instance path, which is a real deployment shape with a permanent answer, and the suite path arrives later as an addition rather than a replacement.
+
+## Global Constraints
+
+- **`CGO_ENABLED=0` everywhere.** No cgo.
+- **rastrillo pinned to `v0.22.0`.**
+- **Read `SKILL.md` from the module before writing app code.** It carries the identity plugin's contract, the scoping rules, and the mass-assignment rule. Where it contradicts this plan, **SKILL.md wins** — say so in the report.
+- **Bare `rst-*` attribute grammar.** A test walks our view FS and enforces it.
+- **Every user-visible string is a catalog key.**
+- **`scope.Owned` must NOT be used for documents.** Verified in plan 1: it is `Where("user_id = ?")`, and applied to a shared table it returns a short list rather than an error — a library that looks empty rather than broken. Docs scopes over its own ownership join, preserving 404-not-403.
+- **No secret, token or address is ever logged.** Magic-link tokens are 256-bit random, stored only as SHA-256.
+- Work on a branch; push regular commits; squash-merge when done, approved, and CI green.
+
+---
+
+### Task 1: Sign-in with a magic link
+
+**Files:**
+- Create: `internal/docs/auth.go`, `internal/docs/auth_test.go`
+- Modify: `internal/docs/app.go`, `cmd/docs/main.go`, `internal/docs/migrations/`
+
+**Interfaces:**
+- Produces: `GET /signin` (the form), `POST /signin` (sends the link), `GET /signin/{token}` (completes), `POST /signout`. A signed-in person is readable by handlers.
+
+- [ ] **Step 1: Read the plugin's contract first**
+
+```bash
+cat "$(CGO_ENABLED=0 go env GOMODCACHE)/github.com/carlosframework/rastrillo@v0.22.0/SKILL.md"
+```
+
+Find what `auth` requires: how it is mounted, what it needs from `sessions`, how it delivers mail, and what it expects of the app. **Quote the relevant part in your report** — later tasks depend on you having read it rather than inferred it.
+
+Note especially: read the viewer with `auth.From(r)` or `sessions.Current(r)`, **never `sessions.UserID`** — it returns `(0, false)` for an email subject, and dropping that `ok` scopes every query to uid 0.
+
+- [ ] **Step 2: Write the failing test**
+
+```go
+func TestSignInRequiredForEverything(t *testing.T) {
+ app, err := docs.NewForTest(t)
+ if err != nil {
+ t.Fatal(err)
+ }
+ for _, path := range []string{"/", "/d/anything"} {
+ req := httptest.NewRequest(http.MethodGet, path, nil)
+ rec := httptest.NewRecorder()
+ app.Handler().ServeHTTP(rec, req)
+ if rec.Code != http.StatusSeeOther && rec.Code != http.StatusFound {
+ t.Errorf("GET %s signed out: status %d, want a redirect to sign-in", path, rec.Code)
+ }
+ }
+}
+
+func TestMagicLinkSignsSomebodyIn(t *testing.T) {
+ app, err := docs.NewForTest(t)
+ if err != nil {
+ t.Fatal(err)
+ }
+ link, err := app.TestSignIn(t, "reader@example.com")
+ if err != nil {
+ t.Fatalf("TestSignIn: %v", err)
+ }
+ // Following the link must establish a session.
+ req := httptest.NewRequest(http.MethodGet, link, nil)
+ rec := httptest.NewRecorder()
+ app.Handler().ServeHTTP(rec, req)
+ if len(rec.Result().Cookies()) == 0 {

+
+Mail delivery in development must not require a mail server: write the link to the log, clearly marked, so `run-dev.sh` remains one command. In any other environment, real delivery is required and its absence is a startup refusal — the same fail-closed shape as the origin check.

+### Task 3: Sample documents worth reading
+
+**Files:**
+- Create: `internal/docs/seed.go`, `internal/docs/seed_test.go`, `internal/docs/seeddata/`
+- Modify: `cmd/docs/main.go`, `scripts/run-dev.sh`
+
+**Interfaces:**
+- Produces: `docs.Seed(ctx, app, owner) error`, and a `-seed` flag that populates a fresh database.
+
+The reading view currently shows two words. Sample content is what makes the canvas, the typography and the empty-versus-full states worth looking at.
+
+- [ ] **Step 1: Write the failing test**
+
+```go
+func TestSeedProducesReadableDocuments(t *testing.T) {
+ app, _ := docs.NewForTest(t)
+ ctx := context.Background()
+ owner := app.TestPerson(t, "seed@example.com")
+
+ if err := docs.Seed(ctx, app, owner); err != nil {
+ t.Fatalf("Seed: %v", err)
+ }
+
+ list, err := app.Store().List(ctx, owner)
+ if err != nil {
+ t.Fatal(err)
+ }
+ if len(list) < 4 {
+ t.Fatalf("seeded %d documents, want at least 4", len(list))
+ }
+
+ // Every seeded document must have real content, through the CRDT.
+ for _, d := range list {
+ text, err := app.Store().Text(ctx, d)
+ if err != nil {
+ t.Fatalf("Text(%q): %v", d.Title, err)
+ }
+ if len(text) < 200 {
+ t.Errorf("%q has %d characters — seed content should be substantial", d.Title, len(text))
+ }
+ }
+}
+```
+
+- [ ] **Step 2: Run and watch fail.**
+
+- [ ] **Step 3: Write the content**
+
+Four to six documents of genuinely plausible prose — several paragraphs each, varied lengths so the list shows range. **Write real sentences, not lorem ipsum**: the point is to see how the canvas reads, and Latin filler hides line-length and rhythm problems that English exposes.
+
+Suggested shapes, all fictional: a project proposal, meeting notes with attendees and actions, a short piece of documentation, a letter, and one deliberately long document so the canvas can be judged at length.
+
+Content lives in `seeddata/` as plain `.txt` files embedded with `go:embed` — editable without touching Go.
+
+- [ ] **Step 4: Apply it through the CRDT, not the database**
+
+Each document's text becomes a **Yjs update applied via `Store.ApplyUpdate`**. It must arrive the same way a person's typing will.
+
+There is no Go-side Yjs *encoder* — `internal/core` applies updates and reads text, and the ABI exposes no insert. **Resolve this and report which route you took:**
+1. Add an ABI function that inserts text into a document and returns the resulting update — a real ABI change, and the honest one if editing needs it anyway (it does; the next plan writes it).
+2. Generate the updates offline with the Node fixture generator (`fixtures/generate.mjs` already uses real `yjs`), commit the `.bin` files as seed fixtures, and have the seeder apply them.
+
+**Route 2 is likely right for this plan** — it reuses machinery that exists, keeps the ABI stable, and the fixtures are honest artefacts of real `yjs`. Route 1 is a bigger change belonging to the editing plan. If you choose route 1 anyway, say why.
+
+- [ ] **Step 5: Run and watch pass.**
+
+- [ ] **Step 6: Wire `-seed` and check it looks right**
+
+Add `-seed` to `cmd/docs/main.go` and use it in `run-dev.sh` so one command gives a populated app. Then run it, curl the list and two documents, and **paste the rendered HTML**. Judge it: does the canvas read well at these lengths? Is the list's grouping doing anything visible with varied dates?
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add internal/docs cmd scripts
+git commit -m "app: sample documents with real content
+
+Four to six documents of plausible English prose rather than lorem
+ipsum, because Latin filler hides the line-length and rhythm problems
+the canvas exists to get right.
+
+Applied as Yjs updates through the CRDT, the same route a person's
+typing will take -- not rows written into a table."
+```
+

+
+### Task 4: Take it live
+
+**Files:**
+- Modify: `.amadan/README.md`, `AGENTS.md`
+
+Docs can now go on a public URL, because every route requires a signed-in person and documents are scoped to their owner.
+
+- [ ] **Step 1: Check what deployment needs**
+
+`carlos email enable` for account `bds`, since magic links need outbound mail. **If email is not available, stop and report** — a sign-in that cannot send its link is not sign-in, and a preview with mail stubbed out is a public app with extra steps.
+
+- [ ] **Step 2: Verify the guards hold**
+
+Corrected in a fix round on Task 1: there is no `-tags release` build and no dev-auth flag to exclude any more — the development-only stand-in identity that check used to verify the *absence* of was deleted outright once real sign-in made it dead code (`internal/docs/devauth.go` and both `cmd/docs/devauth_flag*.go` are gone; `release` is now an undefined build tag, so building with it would silently compile the ordinary binary and verify nothing). Verify instead, against a plain build (`CGO_ENABLED=0 go build ./cmd/docs`):
+
+- an unset `$DOCS_ORIGIN` refuses to start;
+- unset mail configuration (`$DOCS_SMTP_HOST`/`$DOCS_SMTP_FROM`) refuses to start;
+- `$DOCS_ENV=development` with **no** `-env` flag does **not** produce a development app — it must still refuse on the two points above, since `chooseEnv` (`cmd/docs/main.go`) never honours `"development"` from an environment variable, only from the literal `-env` flag. This is the property fix round 2 added: platform instance configuration is environment variables, so `$DOCS_ENV=development` sitting beside `$DOCS_ORIGIN`/`$DOCS_INSTANCE_KEY`/`$DOCS_SMTP_*` would otherwise be a production-reachable path to the public dev `InstanceKey` and to every magic link, token included, landing in the instance's own log.
+
+Paste the refusals — all three.
+
+- [ ] **Step 3: Ship**
+
+```bash
+CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -ldflags "-s -w" -o docs-linux-arm64 ./cmd/docs
+carlos ship --account bds --app docs --kind binary --target linux-arm64 --label "first live" docs-linux-arm64
+```
+
+No `-tags release`: that tag has no meaning left in this codebase (see Step 2).
+
+Then promote and create an instance per the platform's own flow — read `carlos deploy -h` and `carlos instances -h` rather than guessing, and **report each command's real output**.
+
+- [ ] **Step 4: Prove it from outside**
+
+Fetch the public URL and confirm: signed out redirects to sign-in; the sign-in form renders; `/api/version` reports the shipped sha. **Do not paste a working magic link into the report** — it is a credential.
+
+- [ ] **Step 5: Update the warnings**
+
+`AGENTS.md` currently says this app has no authentication and must not be deployed anywhere reachable. **That statement is now false and must change** — say what is true instead: every route requires sign-in, documents are owner-scoped, and the suite path (§8.1.1) is still to come.
+
+---
+
+## Self-Review
+
+**Spec coverage.** Implements §8.1's single-instance shape, §8.2's ownership, §4.2's 404-not-403. Does **not** implement: sharing with guests or links (§8.2's later half), the suite assertion path (§8.1.1), editing, the layout engine, sealing.
+
+**Placeholder scan:** none. Task 3 step 4 names an unresolved choice with a recommendation and requires the implementer to report which route they took — that is a decision point, not a placeholder.
+
+**Type consistency:** `TestSignIn`, `TestPerson` and `TestRequest` are introduced in Tasks 1–2 and used throughout; `Store.Create/List/Get` gain an owner parameter in Task 2 and Task 3's seeder uses the new signature.
+
+**Known risk carried forward:** `internal/core` caps its update log at 4096 with no state export. Seed documents are single updates so this plan will not approach it, but the editing plan will and must not paper over it.

## 8. Identity and sharing
-### 8.1 Sign-in — one relying party
+### 8.1 Sign-in — two shapes, and which one a deployment is
+
+**Ruled by Paul, 2026-08-31, and it reframes what follows.** An earlier draft
+treated the home as the only way in, which made instance-local sign-in a
+stopgap. It is not. There are two deployment shapes and they have different
+correct answers:
+
+- **A single instance** — one team, self-hosted, no suite. It has no
+ "one person, many teams" problem, because there is one instance. So it
+ signs people in **itself**, with rastrillo's `auth` plugin: magic link,
+ auto-upgrading to keymail when the address resolves to a claimed inbox.
+ This is the right answer for that shape, not a placeholder for one.
+
+ **And it is required rather than merely correct.** Factor VII holds that
+ self-hosting is a right and first-class, not a degraded tier. An earlier
+ draft of this section made the home the only way in — which would have
+ obliged a person self-hosting one instance to stand up the entire suite
+ home, split origins, blind-index directory, assertion minting and key
+ rotation included, in order to sign in to their own documents. That is not
+ a degraded tier; it is a prohibitive one, and it would have made
+ self-hosting nominal. *(Argument owed to the Sheets session, 2026-08-31,
+ which is a better justification than the one this spec first gave.)*
+
+ It also sharpens what the home **is**: not "how you sign in", but *how one
+ person reaches many instances without many credentials*. Split origins, the
+ blind index, the rekey journal, the pepper living in exactly one place —
+ every part of it serves that and nothing else. A lone instance has none of
+ that problem and therefore needs none of that machinery.
+- **A suite deployment** — Docs beside Sheets and others, one person
+ spanning several teams. Here three instances must not mean three
+ credentials, which is the problem the home exists to solve, and sign-in
+ moves to its credential origin with instances verifying signed assertions.
+
+So an instance is built to accept identity from **either**: its own
+magic-link flow, or a verified assertion. The second is not a replacement for
+the first; it is what a suite adds.
+
+**Why magic-link-at-the-instance does not violate the one-relying-party
+ruling.** That ruling is about **passkeys** — a person in three teams must not
+enrol three credentials, and `passkey.Config.Origin` derives the RPID from the
+app's own host. Magic link enrols **no credential at all**, so it creates no
+relying party and strands nothing. An instance running it and later accepting
+assertions is not a migration; people simply sign in by a different route.
+
+**And it is consistent with the home's own blindness rule.** The home spec
+rules that **instances hold readable addresses and the home never does**. An
+app instance storing an address is the design, not a deviation — which is
+exactly why `rastrillo/auth` is wrong for the *home* and right for an *app*.

+// TestSigninResponseIdenticalForNonPermittedAddress (auth_test.go),
+// which asserts the two responses byte-for-byte, not merely "both are
+// 303".
+//
+// That guarantee only held for a non-keymail address: on the
+// permitted branch, this used to hand the request to Begin exactly as
+// received, and Begin auto-upgrades a permitted address that resolves
+// to a claimed keymail inbox to the keymail ceremony — a 303 to the
+// keymail authorize URL, not signinPath+"?sent=1". A non-permitted
+// address never reaches Begin at all, so it always got ?sent=1. That

+Quick Reference: Resetting the Site Printer
+
+This covers the shared printer on the second floor. If it is showing a flashing amber light and refusing new jobs, try this before calling facilities.
+
+1. Open the front panel and check the paper path for a jam, even if the display does not report one — the sensor on this model sometimes misses a torn corner.
+2. If there is no jam, hold the power button for five seconds until the display goes dark, then release. Do not unplug it; the soft reset clears the queue without losing its network settings, and unplugging does not.
+3. Wait about thirty seconds for it to reboot. The amber light should turn solid, then go out entirely once it rejoins the network.
+4. Send a one-page test print from any machine on the floor. If it prints, you are done.
+
+If the amber light comes back within a few minutes of the reset, the fault is usually the fuser unit rather than anything a reset can fix — stop here and log a ticket with facilities rather than repeating the reset, which will not help a second time.
+
+For anything involving a physical paper jam that will not clear, do not force the rollers. Log a ticket instead; the previous unit's rollers were damaged this way and the replacement cost more than the service call would have.

+A History of the Millbrook Waterworks
+
+Early years
+
+Before 1887, Millbrook drew its water the way most small towns did: from private wells, a handful of shared pumps on the main street, and, for those who could afford it, a cistern fed by roof runoff. This worked poorly. The town's own health records from the 1870s show repeated outbreaks of what was then called "summer fever" — almost certainly waterborne illness, though the germ theory behind it was still new enough that most residents blamed the weather instead. It took a particularly bad outbreak in the summer of 1883, which killed eleven people in a town of under two thousand, to force the question of a proper water supply onto the town council's agenda for good.
+
+The council spent nearly four years arguing about it. Not about whether a waterworks was needed — by 1884 almost nobody disputed that — but about where to draw from, who would pay for it, and whether the town should build and run it itself or contract the work out to a private company, as several neighbouring towns had done. The private-company faction lost, narrowly, after the council toured a waterworks in a nearby town that had been run privately for six years and found its rates had tripled with no corresponding improvement in service. Millbrook decided to build and own its own works.
+
+Construction and the first reservoir
+
+Construction began in the spring of 1886, drawing from Millbrook Creek roughly two miles upstream of the town centre, where the water was judged cleanest. The site chosen was a natural basin in the hills that needed only a modest earthen dam to become a workable reservoir — this became the original Millbrook Reservoir, still in use today though heavily rebuilt since. The engineer in charge, a Scottish immigrant named Alasdair Reid who had worked on waterworks in Glasgow before coming to North America, insisted on a slow sand filtration system rather than the cheaper alternative of no filtration at all, which was still common practice for a town this size at the time. This decision, more than any other single one, is usually credited with why Millbrook's water-related illness rates dropped so sharply once the works opened, well before most of its neighbours saw similar improvements.
+
+The works opened in October 1887, a year and a half after construction began, at a final cost of just under sixty thousand dollars — considerably over the original estimate, mostly due to unexpected rock excavation for the pipeline route. The opening was marked with a public ceremony at which the mayor reportedly drank a glass of water drawn directly from the new mains, a piece of theatre that was apparently repeated, with much less enthusiasm, at every subsequent mayoral inauguration for the next thirty years.
+
+Expansion through the early twentieth century
+
+The original works served the town well for about two decades, but Millbrook's population nearly doubled between 1890 and 1910 as a shoe-manufacturing plant opened on the eastern edge of town and drew workers from surrounding rural areas. By 1908 the reservoir was running close to capacity in dry summers, and the council authorized a second reservoir, built further upstream and connected by a new pipeline, completed in 1912. This is the reservoir now known locally as the "new" reservoir, despite being well over a century old itself — a naming quirk that has confused more than one newcomer looking at an old map.
+
+The shoe plant itself became the works' single largest customer for several decades, at one point accounting for nearly a fifth of total water usage in town. When the plant closed in 1968, following the broader decline of domestic shoe manufacturing across the region, the waterworks lost enough revenue that rates rose noticeably for several years afterward — one of the few times in the works' history that a single customer's departure showed up directly in ordinary residents' bills.
+
+Modernization
+
+The slow sand filters that Reid insisted on in 1887 remained in continuous use, with periodic resurfacing, until 1974, when the works were modernized with a mechanical filtration and chlorination system more typical of the era. Two of the original filter beds were preserved rather than demolished, at the request of the town's newly formed historical society, and can still be seen — no longer operational, but maintained as an exhibit — at what is now the Millbrook Waterworks Museum, itself opened in 1981 in the original pump house.
+
+Further upgrades followed roughly every twenty years: a new treatment plant in 1996 that finally retired the last of the 1912-era pipework, a supervisory control system installed in 2009 that allowed the works to be monitored remotely for the first time rather than requiring an operator on site around the clock, and most recently a lead service line replacement program begun in 2019 and still ongoing, targeting the roughly six hundred properties in the town's oldest neighbourhoods still connected by pipe materials that predate any of the modern safety standards.
+
+The works today
+
+The Millbrook Waterworks now serves just over nine thousand customers across the town and two adjoining unincorporated areas that have contracted for service over the years. It remains municipally owned, as the 1884 council decided it should be, and is one of relatively few waterworks of its size in the region never to have been sold to a private operator, a fact the utility's own annual report has mentioned, with evident pride, in some form for at least the last twenty consecutive years.

+Dear Members of the Harbourview Allotment Committee,
+
+I am writing about the water butt on plot 14, which has been leaking from its base since the middle of last month. I have tried tightening the tap fitting twice, which helped for a few days each time, but the leak has come back worse than before and I think the seal itself has gone rather than the tap.
+
+I know the committee ordered three replacement butts in the spring for exactly this kind of thing, and I would be grateful if plot 14 could be next in line for one. In the meantime I have moved what I can catch into a spare bucket, but it is not keeping up, and the bed nearest the fence is starting to show it.
+
+I am around most weekday evenings after six if someone from the committee wants to take a look before deciding. Otherwise happy to go with whatever the usual process is.
+
+Thank you for looking into this.
+
+Warm regards,
+Eleanor Vance

+4. Any other business
+
+Discussion
+
+Marisol walked through the intake form redesign. The new version cuts the field count from twenty-three to fourteen, mostly by removing fields nobody was reading back anyway. Tom raised a concern that the shorter form drops the "referred by" field entirely, which the outreach team still uses for their own reporting — agreed to keep it, but move it to an optional section at the end rather than the top.
+
+Dana reported that the second-floor printer has now jammed four times this month, more than any other printer in the building. Facilities quoted three hundred and twenty pounds for a replacement of the same model, which nobody thought was worth it given the repeat failures. Ben suggested looking at the model currently used on the fourth floor instead, which has had no reported issues in over a year.
+
+Feedback from last week's user sessions was mostly positive. Two of the five participants got stuck on the same step — confirming their email address a second time — and thought it was a bug rather than a deliberate confirmation step. Dana will pass this to design as a candidate for the next round of copy changes.
+
+No other business was raised.
+
+Action items
+
+- Marisol: move the "referred by" field to the optional section, have a revised mock ready by Friday
+- Tom: confirm with outreach that the optional placement still works for their reporting
+- Dana: get a quote for the fourth-floor printer model before next week's sync
+- Ben: draft a short note to design about the email confirmation step
+
+Next sync: Tuesday, same time.

+Bring: hard hats (two spare in the van already, check anyway), the folding tape measure not the laser one since the laser one's battery is still on charge, high-vis vests, the site access letter printed and signed, spare batteries for the camera, and a full water bottle each — there is no tap on site.

+Proposal: Refitting the Elm Street Reading Room
+
+The reading room at the Elm Street branch has not been touched since the 2009 renovation, and it shows. The carpet is worn through in front of the returns desk, half the reading lamps no longer hold a bulb steady, and the two armchairs by the window have been patched with tape often enough that patching them again is no longer worth doing. This proposal asks for a modest refit rather than a full renovation: new flooring, working lamps, replacement seating, and a better use of the wall that currently holds nothing but a community noticeboard nobody has updated since March.
+
+Why now
+
+Branch usage is up eleven percent over last year, mostly from people staying for an hour or more rather than just returning books. That is exactly the use a reading room should support, and exactly what this space currently discourages. Members have raised the state of the seating in three of the last four suggestion-box rounds, which is as close to a mandate as a public library ever gets.
+
+What this covers
+
+The scope is deliberately narrow. It does not touch the shelving layout, which works fine, or the circulation desk, which was redone two years ago and does not need attention. It covers: replacing the carpet with the same commercial-grade tile used in the children's section, which has held up well; six new reading lamps with a longer warranty than the last batch; four chairs and a small sofa to replace the taped-up furniture; and converting the noticeboard wall into two more low shelving units, since the noticeboard's actual function has mostly moved to the branch's front window.
+
+Budget and timeline
+
+The estimate, including installation, comes to just under four thousand pounds, most of it in the flooring. We have already spoken informally with the contractor who did the children's section floor, and they could fit this in during the first two weeks of October, which is a slow period for the branch and would let the room close for the shortest practical stretch — four working days rather than the six a full weekend-to-weekend closure would need.
+
+What we are asking for
+
+Approval to proceed with the budget above, and confirmation that October closure dates are acceptable to the branch's other scheduled activities. If approved this month, the work can be finished well before the winter reading push begins in November, when the room sees its heaviest use of the year.
