deployment

"use client"

// DEPLOYMENTS, as a host's dashboard draws them (Vercel's is the reference for layout
// and density, never for its marks): a list of them under filters, and one
// of them in full (`DeploymentDetails`, ui/deployment-details). Drawn from the facts in
// lib/deployment-core, asserted where they enter.
//
//   <DeploymentList deployments={deployments} href={(d) => `/deployments/${d.id}`} />
//
// A ROW is one deployment on one line, 48 px, its columns at fixed widths so every
// row's start where every other's do: the project (its mark and name), the commit's
// message (cut with an ellipsis, whole in its title), the status (a dot, its word, the
// build's duration), the environment (a pill, filled when it is the current one), the
// commit's hash, the branch, and at the end when it was created and who wrote it. A
// row is a link (`href`) or a button (`onOpen`), or neither; the hand lights it.
//
// NARROWER, COLUMNS GO, never squeezed, read from the list's own width (a container
// query, so a narrow column of a wide page drops them too): the branch first, then the
// hash, the message, the environment, then the build's length; the project, the
// status and the time stay, the project's name taking what is left.
//
// THE FILTERS above it: Add Filter (every choice at once) and a dashed chip for each of
// the author, the environment and the status, showing the commonest value; a chip
// opens its choices, read from the deployments the other filters keep, with how many
// each has (so no choice empties the list), and once set it is solid, with its value
// and a way to clear it. The filter is the
// list's own (`defaultFilter`) or the consumer's (`filter`, `onFilterChange`).
//
// THE SMALL PARTS are exported for a page of its own: `DeploymentStatus` (a status's
// dot, amber and pulsing only while it builds, green ready, red error, quiet queued or
// canceled, in the tokens' tones), `EnvironmentBadge`, `CommitRef`, `BranchRef`,
// `ProjectMark`, `AuthorFace`. Times are relative-time's, said as `TIME_WORDS` from
// `now` (a page's own clock, a replay's); without it, from the reader's clock, each
// label ticking while it is seen. A build's running length ticks every second while
// it builds.
//
// Plain, the page's colours: a box of hairlines on the page. `material="glass"` (or a
// glass provider round it) is a pane of the material's glass. Inside a frame already
// drawn (a panel, a tabs box) it draws no box of its own.

// ONE DEPLOYMENT IN FULL, the body of a host's deployment page (the rows and parts are
// ui/deployment's). It draws what the deployment carries and nothing else: a part the
// host does not know is absent, never an empty box, a made-up check or a button with
// nowhere to go (lib/deployment-core, "known").
//
//   <DeploymentDetails deployment={d} links={[…]} actions={[…]}>
//     <DeploymentBuild />
//     <DeploymentSummary />
//     <DeploymentChecks />
//     <DeploymentStep value="domains" title="Assigning Custom Domains" state="passed">…</DeploymentStep>
//   </DeploymentDetails>
//
// Steps may be wrapped in the consumer's own components; a deployment carrying a build
// must show it (DeploymentBuild among them), or the page throws.
//
// THE FIRST BOX: its head (Share for a deployment with an address of its own, Logs for
// the build shown below, Visit with every domain serving it under its chevron, ⋯
// with the consumer's verbs), a picture of the page beside the facts when the host
// took one, the facts (who created it and when, its status, how long the build took
// and when it ended for a build the host saw, its environment and whether it is
// current), the domains serving it (three, the rest behind +N), its source (the
// branch, the commit), and the settings the platform recommends when it recommends.
//
// THE STEPS are the children, each a section that opens in place (accordion), its
// state at its end: a check when it passed, a clock while it waits, a spinner while it
// runs, a cross when it failed, a dash when it was skipped. The consumer composes the
// ones it can feed, and each built-in step asserts its part is there:
//
//   DeploymentBuild     the build's log (ui/log), its own height, drawing no box of its
//                       own. Its warnings and errors are counted from its lines; a count
//                       is a toggle that shows that level and above. Run Summary lays
//                       the build's spans beside it as a trace (ui/trace), linked both
//                       ways as lib/telemetry's demo links them. The length the build
//                       took, or has taken.
//   DeploymentSummary   what the build put out (functions, static assets, the
//                       middleware), narrowed by kind from Resources.
//   DeploymentChecks    what ran on it once built.
//   DeploymentStep      any other step the host reports, its state given (the domains
//                       being pointed at it, a migration, a promotion).
//
// THE FOOT: the consumer's links to the project's other pages (`links`), a card each.
//
// Plain, boxes of the page's card on the page; glass, panes of the material's glass
// (panel). Every control is the registry's own: Button, Badge, Popover, the menu's
// dropdown, Copy, Accordion, Log, Trace.
