feat(admin): the Modules screen (phase 4, slice 2)
The screen slice 1's API was written for: install from a release URL, enable, disable, uninstall, purge, and restart. Admin-only, matching the server, and core's own screen because it is how a module reaches the volume at all. 182 client tests (+21), manifest and OpenAPI unchanged. Everything that decides what a row SAYS and which buttons it offers is in `lib/moduleAdmin.js` -- plain JS, so the DOM-less runner can reach it, the same reason `lib/adminNav.js` is. The JSX renders what it returns. Three sources of truth, and they are allowed to disagree -------------------------------------------------------- The row records what the operator decided and what the last boot did; the loader says what is mounted and answering; the volume says whether there is a directory at all. Picking one and rendering it is simpler and lies. The case that makes it concrete is the one decision 3 creates on purpose: disable a module (its onShutdown runs) and enable it again, and the row says `enabled` while the loader still says `disabled` because nothing can start it before a restart. Neither "Running" nor "Disabled" is true; "Restart to start" is. Two shapes that are deliberately unlike the rest of the panel: the restart is a BANNER, because a restart is a property of the server rather than of a module and an operator who installed three modules should restart once; and purge is offered inside the uninstall flow as a second confirm, because purge.sql lives inside the directory being deleted and there is no later. What the browser found that no test could ----------------------------------------- Installing over a row the previous boot had left `startup_failed` rendered "Failed at the require stage: module directory not present on the volume" one second after the files had been written to the volume -- and, because that branch is not pending, it suppressed the restart banner the install had just told the operator to use. Every unit test passed, because none of them had modelled a stale row plus a fresh install. The fix is a derivation rather than a special case: the loader scans the volume once at require time, so a module that is on the volume now and has no live record arrived after that scan, and everything the row says about it predates the install. That check runs before the failure one. The same class, one place further on: an upgrade leaves the old code loaded, so the row's version is a promise about the next boot. `liveVersion` (slice 1) lets the screen say "Restart to finish upgrading" instead of reporting the new version as running. Verified against a live server and the real published release: pasted the v0.3.0 install-manifest URL, restarted, watched the module register its five mounts and seven streams and its own nav rows appear in the sidebar. Disable ran its onShutdown for real -- the uo-link WebSocket closed, its routes went to 404, and it left /public/modules -- and enable then showed the decision-3 state with the banner. The restart button itself was exercised through its endpoint rather than clicked, because a window.confirm wedges the browser automation. Co-Authored-By: Claude <noreply@anthropic.com> |

fix(modules): three defects a real install exposed (phase 4, slice 1)
Standing the slice-2 screen up against a live server and installing the
published module-uo v0.3.0 through it found three things, none of which any
unit test in this repo could have caught. Two of them are older than this
phase.
1. The boot refresh nulled every install's provenance
--------------------------------------------------------
`installed_modules.source` and `.sha256` exist so the admin panel can say
where a module came from. They never survived a restart.
`lifecycle.boot()` re-records every scanned module with no source and no
sha256 -- correctly, because a scan finds a directory and never where it came
from -- and `upsert` assigned both columns unconditionally. So an install's
provenance lasted exactly until the restart that install asked for, and the
screen then described a module installed from a URL as "placed on the volume
by hand". Verified live: install, restart, provenance gone.
Nothing could have caught it before now. Phase 4 wrote the first non-null
value these columns had ever had, so lifecycle.js's comment asserting that
"recordInstalled leaves what it is not given" described an intention rather
than the statement below it -- and modules.model.test.js's fake reproduced
the defect faithfully, assigning unconditionally just like the SQL.
Fixed with COALESCE(VALUES(col), col): a value overwrites, a NULL leaves what
is there. The fake now matches, and two tests pin both directions -- a boot
refresh must not wipe it, and a re-install from a new URL must still replace
it, or the column would become write-once and an upgrade would for ever show
where the first version came from.
2. The restart killed the server on Windows instead of stopping it
------------------------------------------------------------------
The route called `process.kill(process.pid, 'SIGTERM')` to reach server.js's
graceful-shutdown handler. That works on Linux. **Windows has no POSIX
signals, and Node documents SIGTERM there as unconditional termination of the
target process** -- so on a Windows host the restart killed the server
outright: no module onShutdown, no listener close, no pool close, no log
flush. Observed exactly that: the process was gone and the shutdown handler
had logged nothing at all.
`process.on('SIGTERM', ...)` is an ordinary EventEmitter listener, so
`process.emit('SIGTERM')` reaches the same handler on every platform without
involving the OS. One shutdown path, still; it just gets there by an event.
Deployment is Linux containers and would never have shown this. Development
is not, and neither is the smoke that found it.
The test was worse than useless: it stubbed `process.kill` and asserted it
had been called with SIGTERM, which is precisely the call whose MEANING
differs by platform. It now waits for the SIGTERM EVENT -- what server.js is
actually subscribed to -- so a pass here means the handler would run.
3. `present()` did not publish the running version
--------------------------------------------------
An upgrade writes new files and a new row while the old code stays loaded, so
the row's version is a promise about the next boot rather than a description
of this one. Adds `liveVersion` from the loader beside `liveState`, so the
screen can tell the two apart instead of reporting the new version as running.
723 server tests (+2), manifest and OpenAPI both unchanged.
