The real fill failed at "diigo returned 44 items for page 167 of 168":
diigo's `total` overstates what load_user_items returns, so the true
last page looked short and the guard took it for a capped page size.
A short page that isn't the last by `total` now fetches the next page
(paced like any diigo call): empty means the data really ends there —
accepted, with a "total-overstated" notice logging total vs actual;
anything else means items would be skipped — refused, the message now
giving both counts. The fake gains an account whose total claims 60
more than it has; a fill on it runs to done.

Asked for 128, diigo returned 100 (the short-page guard caught it on the
first real fill), so PAGE_SIZE = 100: ~168 pages for 16.7k bookmarks.
The same run showed a fill job outliving a page-size change: progress
counted in 24s ("page 25 of 698") resumed as if counted in 128s. Stored
state reinterpreted, so: FillStatus records pageSize (additive; jobs
saved without it counted in 24), and a job whose size differs from
PAGE_SIZE fails with "page size changed …; start the fill again"
instead of resuming; starting again replaces it. Tested with the old
shape in storage.

PAGE_SIZE = 128 (was 24), one constant for the fill job, public pages,
dumps, and DiigoBridge, so a cache never mixes sizes: ~131 pages instead
of ~698 for 16.7k bookmarks.
Cache invalidation, agreed beforehand: pages are cached by (page number,
size), so pages cached at 24 become misses and refetch at 128. Items are
keyed by link_id and just re-upsert; nothing is lost.
Unknown whether diigo honors count=128, so a short page that isn't the
last is refused loudly (logged, thrown; a fill fails with the reason)
rather than silently skipping items. The fake gains a capped account to
test it; the plain account grows to 300 (3 pages), the deep one to 6000.

Past the transitional idiom: the cache logic (DiigoCacheLogic,
PublicCacheLogic in cache.ts) requires its Clock, with no default, so
cache.ts reaches no ambient time. The worker's entry module is the
edge: it makes the live clock and exports the runtime-constructed
DiigoCache/PublicCache as (ctx, env) subclasses that supply it (the
Cloudflare constraint: the runtime constructs DOs with ctx and env
only). Binding class names are unchanged, so stored state is too. The
tests' FixedClockCache extends the logic class.

No module-level liveClock: the live clock is made in the default
argument expression, at the edge where the runtime constructs the DO,
so module scope holds no powerful object.

Ocap discipline: no ambient time in logic. PagedCache reads time and
waits only through a Clock { now, sleep }, a default constructor
argument (the live clock; the runtime constructs DOs with ctx and env
only). The fill job's timestamps and alarms, the etch time, and the
diigo-call pacing all go through it.
Tests interpose through the constructor: tests/test-worker.ts (now the
tests' main module) adds FixedClockCache, bound as CLOCKED_DO, and a
test pins startedAt, updatedAt, and the alarm time to the fixed clock
(an ambient new Date() fails it).

POST /_fill (cache id in the body; target private|public; action
start|stop) starts or stops a background walk of every diigo page into
the cache. DO alarms advance it pagesPerStep pages per step (default
20), a second apart; progress (FillStatus) is stored in the DO after
each page, so it survives eviction. Cached pages are skipped; starting
while running rejoins the job; a stop mid-step wins; a failure is
recorded with its reason and logged once. The created page gets fill
buttons; the public page shows "filling: n of m pages".
Fill state is new, additive DO storage (fill, fillStep): no existing
state changes meaning.
The 13 fill specs are unskipped and green, plus one: a fill makes one
diigo call per page fetched.

Two bugs in page()'s miss path, found while building the fill job:
- the webapp stubs (app, pathjoin, query) were never disposed, which
kept the DO from being evicted (evictDurableObject hung after a single
miss); they are now disposed once the page is in hand
- a miss on page n > 1 also fetched page 1 and threw it away, doubling
diigo calls; every page carries `total`, so only page n is fetched
Regression test: a miss, then eviction, then a cache hit. tsconfig adds
the ESNext.Disposable lib for Symbol.dispose.

A button that grabs every page into a cache: owner-only POST /_fill
(cache id in the body; target private|public; action start|stop),
advanced by DO alarms a few pages per step, progress stored in the DO
(new, additive state) so it survives eviction, cached pages skipped,
a rerun rejoins the running job, failures recorded and logged once.
The created page gets the button; the public page shows progress.
startFill/fillStatus/stopFill on PagedCache are JSDoc'd stubs; 13
specs are describe.skip until it lands (alarms driven by
runDurableObjectAlarm, eviction by evictDurableObject).

The dump worker becomes a page cache: a hit is served from DO SQLite
storage with no diigo call; a miss asks the webapp instance in the
cache's wiring and etches the page.
- two independent caches, one behavior (PagedCache): DiigoCache keeps
every item; PublicCache keeps shared items only, dropping private
rows before they are stored; served at /public/<username> (HTML page
form, or JSON)
- create flow on one port: /_connect relays webapp's mint form, /_mint
proxies the mint, /_wire wires a private or public cache; /_publish
adds a public cache later
- ids are webkeys: kept out of URLs (POST bodies), shown and logged
only as a hash fingerprint; saved to the password manager under the
holder's petname (never sent to the server)
- items keyed on diigo's link_id; username from u_name; unkeyable
items and every failure path are logged; each page read logs hit/miss
- tests run the real worker + DOs in the vitest pool against a fake
webapp (tests/fake-webapp.js)
