 `v0.16.27` fixes the real, deeper causes behind two v0.16.26 fixes that turned out to be incomplete -- both confirmed by rendering the actual markup and CSS in a headless browser and measuring the real computed heights before and after, rather than reasoning from the stylesheet alone. The API Access summary bar was still rendering 32px taller than the Users tab's summary bar (84px vs 52px, measured) even after last release's `white-space`/`flex-shrink` fix, because that fix addressed a different problem (text wrapping) than what was actually happening here: the sitewide `label{margin:var(--space-4) 0 0}` rule -- meant to space a stacked field label above its input -- was also landing on the "Hide revoked" toggle, since it's built as a `<label>` too. That gave it a lopsided 16px top margin with no bottom margin, and a flex row sizes itself to its tallest child's full margin box, so the whole bar grew to accommodate it. This is the same bug class the System tab's Docker toggle was already patched for (`.system-integrations .check-control{margin:0}`) -- the API tokens toggle just didn't get the same treatment when it was added. Fixed by zeroing that toggle's margin the same way. (A real, much smaller ~16px difference remains between the two bars, and that part is expected: the API bar contains an actual bordered, padded checkbox control, and Users' doesn't, so its row is naturally a little taller than one built from plain text alone.) Separately, the "Pick container" button was still measurably 2px shorter than its target field (41px vs 39px, measured) even after realigning their margins -- the button and input use different padding values (11px vs the shared 12px `--space-3`), and no amount of margin/alignment fiddling closes a real padding gap. Gave both an explicit `height:44px`, the same fixed control height already used throughout the app for this exact kind of row (dialog inputs, the log host selector, Settings target fields), so they're now pixel-identical rather than approximately matched.
 
 `v0.16.28` closes the API Access summary bar's remaining height gap against every other tab's summary bar (Users, Groups, Hosted Sites, Proxy Hosts, and so on) -- measured with the same headless-browser approach as v0.16.27: 68px vs 52px before this release, now 53px vs 52px, a difference too small to see and driven only by the checkbox input's own fixed 17px size (every checkbox in the app is 17px; shrinking just this one to save the last pixel would have made it the odd one out). The remaining gap came from the "Hide revoked" toggle's bordered, padded pill styling -- a treatment none of the other tabs' summary bars use, since none of them embed a control inline with their stat counts. Rather than keep splitting the difference, the toggle now sits flush in the bar like the stat counts beside it: no border, no background, no padding, and its label text no longer inherits `.check-control`'s 1.35 line-height (meant for roomier form checkboxes, not a compact inline one). It still reads clearly as an interactive control -- the checkbox itself, its green accent color, and the pointer cursor on hover are untouched -- it just no longer sits inside its own nested box within the already-bordered summary bar.
+
+`v0.16.29` adds a hero panel to the top of the Administration > System tab -- a single, visually distinct "one-stop shop" for this container's live CPU, memory, swap, disk, and network numbers, plus request throughput, all in one place instead of scattered across the plain status tiles below it. CPU, memory, and swap all read directly from this container's own cgroup v2 files (`cpu.stat`'s `usage_usec`, `memory.current`/`memory.max`, `memory.swap.current`/`memory.swap.max`) rather than host-level figures, on the same reasoning already settled for this feature: Site Gateway is rarely the only thing running on the host, so a host-wide number would be misleading in a dashboard scoped to one container. CPU percent is computed from two samples of the cumulative `usage_usec` counter taken a poll apart, normalized against `cpu.max`'s quota when one is set (or the host's core count when it isn't); memory and swap read straight off their `.current`/`.max` pairs, with swap showing "Off" rather than a stale percentage when the container has none configured. Disk reuses the same `statfs`-on-the-data-volume approach the System tab's storage breakdown already used. Network throughput is new: since `/sys/class/net/*/statistics/{rx_bytes,tx_bytes}` are cumulative counters too, a background sampler reads every non-loopback interface every 5 seconds and keeps a rolling rate in memory, so the hero panel always shows a real, smoothed rate rather than a lifetime total or a jittery two-reads-per-request estimate. Request throughput reuses the exact number already shown on the main Dashboard ("requests in the last minute"), so the two stay in sync without duplicating the underlying query. Each stat degrades independently and visibly rather than silently: a metric with no readable source (cgroup v1 hosts, a sandboxed `/sys/class/net`, and so on) shows a dash and a one-line explanation instead of a wrong number or a blank space, and CPU/memory/swap/disk fills turn amber past 75% and red past 90%, matching the color language already used elsewhere in the app for degraded/warning states.
+
+`v0.16.30` fixes two numbers on the System tab's new hero panel (added in v0.16.29) that were technically correct but meant the wrong thing. CPU percent was always computed against either a real Docker `--cpus` quota or, absent one, the *host's total core count* -- so pinning the container to 2 specific cores (`--cpuset-cpus`, Unraid's CPU pinning field) didn't change the denominator at all, since pinning caps which cores can run without capping how much of them can be used, and `cpu.max` stays `max` either way. CPU now checks `cpuset.cpus.effective` (the actual pinned core list, correctly counting ranges like `0-1,4`) whenever there's no real quota, and the hero panel's detail line now says which denominator applies -- "Of N allocated CPUs" for a real `--cpus` quota, "Of N pinned cores" for cpuset pinning with no quota, or "Of host's N cores -- no limit set" when neither is configured -- instead of always claiming "Of this container's CPU quota" even when there wasn't one. Swap had a similar honesty problem: without an explicit `--memory-swap` limit, `memory.swap.max` reads `max` (unbounded, shared with the host's swap) rather than "0," but the panel showed a bare "0 B" that read like a real, enforced cap. It now only shows a percentage when a real swap limit exists; otherwise it shows the actual bytes in use with "Unlimited -- shares host swap" instead of implying a limit that was never set.
+
+`v0.16.31` adds the two remaining items from the System tab hero panel's fix list. First, the panel now keeps itself current while you're actually looking at it: a lightweight timer polls `/api/system/health` directly every 7 seconds whenever the System tab is the visible admin panel, separate from the app's full `refresh()` (which also refetches sites, proxies, certificates, and everything else) so it stays cheap on a fast interval, and it's a no-op the moment you navigate away rather than continuing to poll in the background. Previously the hero panel only updated on initial page load or whenever *anything else* in the app happened to trigger a `refresh()` -- sitting on the tab watching it did nothing. Second, a new `DATA_DIR_LIMIT_GB` environment variable lets an operator tell the Disk stat what's actually assigned to this deployment -- a dedicated share or zvol smaller than the whole host volume, for instance -- instead of always showing usage against the full underlying filesystem size. This is necessarily display-only, since Docker has no real per-container disk-space quota the way it does for CPU (`cpu.max`) or memory (`memory.max`); actual usage and free space still come straight from `statfs` on the real volume, only the percentage's denominator and the "used of X assigned" label change. Set past 100%, the stat turns red rather than silently capping, since exceeding an assigned allowance is a real, meaningful warning rather than a display bug.
+
+`v0.16.32` fixes a real bug in v0.16.31's `DATA_DIR_LIMIT_GB` disk allowance: the percentage it computed compared an assigned per-app allowance (e.g. 30 GB) against `statfs`'s used-space figure for the *entire filesystem* behind `/data` -- which on a shared array, cache pool, or any volume with other things living on it, has nothing to do with how much Site Gateway itself has actually written. A container assigned 30 GB sitting on a host volume that's 160 GB full of unrelated data showed as "534% used," which is a meaningless number dressed up as a warning. When `DATA_DIR_LIMIT_GB` is set, the Disk stat now compares against Site Gateway's own actual footprint instead -- the same recursive `/data` walk (`directorySize()`) the System tab's storage breakdown already performs -- so the percentage reflects what this app has actually written, not what else happens to share its disk. That walk only runs when the environment variable is actually set, since it isn't free and the whole-volume `statfs` numbers (used with no assigned limit configured) don't need it.
+
+`v0.16.33` fixes the System tab hero panel's Network stat printing absurd, layout-breaking values like "846.7603211009175 B/s" instead of a clean rounded number. Root cause: `formatBytes()` only rounds once a value crosses into KB -- below 1024 it returns the number exactly as given, which has always been fine because every other caller passes it a file size (always a whole integer). The Network stat is the first caller to feed it a computed rate (bytes divided by elapsed seconds), which is almost never a whole number, so sub-1 KB/s readings rendered with a dozen decimal places and wrapped onto a second line, breaking the hero panel's layout. `formatRate()` now rounds to the nearest whole byte before handing off to `formatBytes()`, matching what every other value passing through it already looks like.
+
+`v0.16.34` fixes the System tab hero panel's helper text not lining up across columns -- Network and Throughput don't have a meaningful usage bar (neither is a percentage of anything), so that bar was hidden with `display:none`, which removes it from the flex layout entirely rather than just hiding it. The other four columns (CPU, Memory, Swap, Disk) still have their bar taking up space between the value and the detail line, so Network and Throughput's detail text sat visibly higher than everyone else's, breaking the row's shared baseline. Switched to `visibility:hidden`, which keeps the bar's space reserved without drawing it, so all six columns now keep identical vertical rhythm and every detail line lands on the same line.
+
+`v0.16.35` unifies the Dashboard's Runtime/System panel with the Administration > System tab's hero panel instead of the two showing different, disagreeing numbers for the same underlying stats. The Dashboard's Memory tile used to read `process.memoryUsage().rss` -- the Node process's own footprint, not the container's real usage -- while the System tab's hero (added in v0.16.29-34) correctly read cgroup v2's `memory.current`. There was no CPU stat on the Dashboard at all, and "Site Gateway data" plus "Storage available" were two separate numbers where the System tab's Disk stat already combined them into one coherent, `DATA_DIR_LIMIT_GB`-aware percentage. Rather than keep two implementations in sync by hand, the Dashboard's panel is now the exact same hero component -- same markup builder, same `renderHeroPanel()` function, same `/api/system/health` endpoint, same polling-while-visible pattern -- so the two can't disagree again, because there's only one implementation computing the numbers. The Dashboard's copy shows CPU, Memory, Swap, Disk, Network, and Uptime; Throughput is left out there since the Dashboard already has its own "requests / min" chip in its metric strip and showing the same number twice added nothing. Uptime keeps ticking client-side exactly as it did before (same `updateDashboardUptime()` timer, just now living inside the hero's sixth slot instead of a standalone tile). Everything else that used to live in that panel -- Site Gateway version, Caddy version, Database status, and Public IP -- moved to the Administration > System tab's existing Version panel, alongside the Site Gateway version and access-URL details already shown there, so nothing was lost, it just now lives with the rest of the deployment's operational metadata instead of being split across two pages. The Dashboard's hero grid also gets its own CSS breakpoint (3 columns by default, 2 below 900px) rather than reusing the System tab's viewport-keyed breakpoints, since it sits inside the Dashboard's half-width two-column layout rather than a full-width panel and would otherwise stay cramped at 6 columns on an ordinary desktop window.
+
+`v0.16.36` opens `/api/system/health` up to every signed-in user instead of administrators only, so the Dashboard's hero panel (unified with the System tab's in v0.16.35) actually populates for standard users instead of sitting on dashes forever. It's a read-only endpoint with nothing destructive or sensitive behind it -- live CPU/memory/swap/disk/network numbers a standard user could already roughly infer from the Dashboard running fast or slow -- so it now follows the same no-admin-gate pattern as `/api/dashboard` rather than the stricter pattern used by the rest of `/api/system/*` (storage breakdown, restart, restart-policy), which stay administrator-only since those are either configuration detail or capable of restarting the container. Worth keeping in mind: when `DATA_DIR_LIMIT_GB` is set, each poll of this endpoint does a real recursive walk of `/data` to compute Site Gateway's own footprint (see v0.16.32) -- with multiple people viewing the Dashboard at once, each on their own 7-second timer, that's now multiple concurrent walks instead of one administrator's. Not a problem at ordinary usage levels, but worth revisiting (e.g. a shared, briefly-cached snapshot) if it's ever noticeably heavy with a lot of concurrent viewers.
+
+`v0.16.37` combines the documentation catch-up for the hero panel arc (v0.16.29-36: README feature bullets and the environment-variable table, plus new "Live resource panel" and "Version" sections in the in-app manual's Administration System article, and an updated Dashboard "Runtime & System" article) with a real fix found while reviewing the Dashboard's hero panel live: the Throughput chip next to it (requests/min) was still only updating on the old 30-second `refreshDashboard()` timer, not the hero's 7-second poll, even though `/api/system/health` already computes that exact number on every call and the Dashboard was just discarding it. `refreshDashboardHero()` now also updates the Throughput chip from that same response, so it refreshes on the same cadence as the rest of the hero instead of lagging behind it by up to 23 seconds.
+
+`v0.16.38` fixes the Dashboard hero's Uptime tile reliably showing "0m" right after a page load or refresh, before slowly counting up from there rather than showing the real elapsed time immediately. Root cause: a 1-second ticker (`setInterval(() => updateDashboardUptime(), 1000)`) has always run independently of the real data fetch, calling `updateDashboardUptime()` with no argument once a second while the Dashboard is visible. The function's old anchor logic (`window.__dashboardStartedAt || (window.__dashboardStartedAt = ...)`) treated a bare, argument-less call as "anchor starts now" (zero elapsed), and because that anchor was set-once, a later call carrying the real `uptimeSeconds` from `/api/dashboard` was then a no-op -- the wrong zero-based anchor had already won the race, almost every time, since the ticker fires every second and the dashboard fetch takes at least one network round trip. `updateDashboardUptime()` now only ever sets the anchor from a real, finite `seconds` value, and does so every time real data arrives rather than once -- so it can't be raced by the bare ticker call (which now just re-renders using whatever anchor already exists, or does nothing until one does), and it also self-corrects if the container genuinely restarts while the page stays open, instead of drifting forever from a stale first anchor. Separately, confirmed by inspection (not a bug, but worth documenting): the Administration System tab's Version panel does *not* tick client-side the way the Dashboard's hero does -- its Uptime is a static string recomputed only when the page's shared dashboard data refetches (on load, or every 30 seconds while the Dashboard view specifically is the active one), so it can go visibly stale while sitting on the Administration tab. Left as-is for now since it's presented as build/version metadata rather than a live stat, but flagged in case a ticking version is wanted there too.
+
+
+`v0.16.39` retires the Dashboard Uptime tile's separate 1-second client-side ticker, the same mechanism behind the v0.16.38 "resets to 0m on page load" bug, in favor of treating Uptime as just another field on the shared 7-second `/api/system/health` poll that already drives CPU, memory, swap, disk, and network on both the Dashboard and the Administration > System tab's hero panel. Revisiting the ticker after fixing its race condition, it turned out to be solving a precision problem the display doesn't actually have: `formatDuration()` only ever renders minute-level granularity ("2h 59m"), never seconds, so a per-second tick never changed what was on screen between one 7-second poll and the next. `systemHealthSnapshot()` now includes `uptimeSeconds` (from `process.uptime()`, the same source `dashboardSnapshot()` already used), and `renderHeroPanel()`'s former `includeThroughput` boolean became a `sixthSlot` option ("throughput" for the System tab, which has no other requests/min display, or "uptime" for the Dashboard, which already shows Throughput in its own chip) so the sixth hero slot can be either stat without a special case. The client ticker, its anchor state, and the whole race-condition class it enabled are gone: one poll, one code path, six stats, no anchor to get out of sync.
+
+
+`v0.16.40` moves the Administration → System tab's Version panel Uptime figure onto the same 7-second `/api/system/health` poll driving the hero panel above it, instead of only updating when the page's slower, general dashboard snapshot refetches (on load, or every ~30 seconds while the Dashboard view specifically is active). Found while reviewing the v0.16.39 change: the hero's own Uptime slot was now current to the second, but the separate Version-panel line right below it — the same number, shown twice on the same page — could still be stale by up to half a minute or more. `renderSystemStatus()`'s Uptime is now wrapped in its own `#system-version-uptime` span and updated by a small `updateSystemVersionUptime(health)` helper, called both from the initial render and from the same 7-second timer that already refreshes the hero, so the two Uptime figures on that page can no longer drift apart.
+
+`v0.16.41` cuts redundant work out of the app's shared `refresh()` cycle -- the single function that populates nearly every page (Hosted Sites, Proxy Hosts, Redirects, Streams, Access Lists, Dashboard, and Certificates all pull from it) -- after a user reported the whole site feeling slow to refresh, most concretely on a plain reload of Hosted Sites or Proxy Hosts. Two real causes, found by reading the actual request path rather than guessing: first, `certificateInventory()` (which walks the certificate directories and parses every `.crt`/`.pem` file on disk) was being fully recomputed from scratch on every single call, and `refresh()` calls it twice per cycle -- once via `/api/dashboard`, once via `/api/certificates` -- so a normal page load did that walk-and-parse work twice for identical results. It now carries a short (3 second) in-memory cache, well under the 7-second hero-poll interval, so back-to-back calls within a cycle share one real disk walk instead of two, and nothing on screen goes more than one cycle stale. Second, and the bigger one: `refreshPendingProxies()` -- triggered whenever a page loads with any enabled proxy that doesn't have cached upstream-health data yet, which is the common case right after a page load or a new proxy -- was calling the *entire* `refresh()` again at +1s, +2s, and +3s until every proxy's health came back. That meant a single pending proxy could quietly trigger three additional full 8-endpoint refetches (each with its own pair of certificate walks) in the six seconds after a page appeared to have finished loading. It now re-fetches only `/api/proxies` on those retries, since upstream health is all it was ever waiting on. Together these remove the two largest sources of duplicated, unnecessary work from the most-used code path in the app; whether they fully account for the reported slowness or whether a client-side rendering cost remains to find is still open and being evaluated against a real before/after comparison.
+
+`v0.16.42` finds and fixes the real, dominant cause of the site-wide slowness reported after v0.16.41: a live Network-tab capture from the user's own browser showed a flood of requests to `/api/logs/prune/preview`, some queued for over 15 seconds, with unrelated requests (`/api/dashboard`, `/api/system/health`, `/api/system/security`, `/api/system/storage`) stuck at nearly identical multi-second times in the same batch -- the signature of one blocking operation stalling everything behind it, not several independently slow endpoints. Root cause: `renderRetentionPreview()`'s `setInterval(..., 2000)` polls that endpoint every 2 seconds forever, on every page of the app, not just Administration -> Logs & retention, because its "does the panel exist" guard checks a `<section>` that's written into `index.html` from page load and only ever CSS-hidden -- so the guard was always true, everywhere. There was also no protection against a new poll firing while a previous one was still in flight, so once the server answered slower than 2 seconds even once, requests piled up and never caught back up. Compounding it: `previewPruneEvents()` runs five synchronous SQLite COUNT queries, and one of them (`audit_events`) had no index at all -- a full table scan, every call -- and because this app's SQLite queries run synchronously, that scan doesn't just slow its own request, it blocks the entire Node process for every other request being served at that moment. Fixed on both sides: `renderRetentionPreview()` and the sibling `renderRetentionRunStatus()` (previously also running unconditionally every 500ms) now check that the retention panel is actually visible, not just present in the DOM, before doing any work, and an in-flight guard stops a new preview poll from starting until the last one has landed; `audit_events` now has the same `(instance_id, created_at)` index every sibling events table already had. Together these should remove the vast majority of the "8-10 seconds to load a simple page" behavior reported after v0.16.41 -- that fix (deduplicating certificate-inventory work) was real but minor by comparison to this one.
+
+`v0.16.43` scopes page refreshes to the page actually being viewed, instead of every refresh across the entire app unconditionally re-fetching everything -- Hosted Sites, Proxy Hosts, Redirects, Streams, Access Lists, Groups, the full Dashboard snapshot, and Certificates -- regardless of which single page triggered it. This was confirmed directly from the user's own account of the behavior ("if I'm on Hosted Sites and click refresh, it appears the whole entire site refreshes") and traced to a single shared `refresh()` function that every action in the app called: creating or editing a hosted site or proxy, toggling one on or off, deleting an entry, saving gateway settings, and re-syncing the gateway all ran the identical 8-endpoint fetch no matter which page initiated it. `refresh()` and its endpoints are now built from one shared map (`REFRESH_ENDPOINTS`), and a new `refreshCurrentView()` fetches only the state keys a `VIEW_REFRESH_KEYS` table says the active view actually renders -- Hosted Sites now refetches just `sites`, Proxy Hosts just `proxies`, Streaming just `streams`, Redirects just `redirects`, Access Lists just `accessLists` and `groups`. Every action listed above that's only ever reachable from one specific view (creating/editing/toggling/deleting a hosted site or proxy) now calls `refreshCurrentView()` instead of the full `refresh()`. Overview keeps the full, unscoped fetch deliberately: its attention list and the sidebar's per-section counts summarize the whole gateway, not one section of it, so scoping it would defeat the page's purpose; the initial page load (`boot()`) and the gateway re-sync button (only reachable from Overview) are unchanged for the same reason. A new generic refresh button (the same "↻" icon `refresh-health` already used) now appears on every page except Logs (which keeps its own dedicated "Refresh logs" button) so every view has an explicit, page-scoped way to pull fresh data without a full browser reload -- previously several views (Hosted, Proxy Hosts, Streaming, Redirects, Access Lists) had no refresh control of their own at all and only ever picked up new data from the page's initial load or the next full-page reload. One deliberate trade-off: sidebar badge counts for sections other than the one currently being viewed are not part of a scoped refresh and can go briefly stale until the next full refresh (a fresh page load, or a visit to Overview) -- intentional, since fetching data a page doesn't display was the entire problem being fixed here.
+
+`v0.16.44` is a temporary, diagnostic-only release -- no behavior changes, just logging -- added after v0.16.43 (which fixed the app from over-fetching per page) didn't resolve the user's reported 6-14 second page loads. A Network-tab Timing capture the user sent for a single `GET /api/sites` request showed DNS and TCP connection at 0-7ms but "Waiting" (time to first byte) at 7485ms -- almost the entire delay happened server-side, before the app sent back a single byte of what should be a near-instant, in-memory list. Since this codebase's database and JS execution is single-threaded, that pattern (a trivially cheap request taking seconds) points to something else blocking the whole process at that moment, not a cost specific to any one endpoint. The leading suspect: `importAccessLogsToSqlite()`, a job that runs every 30 seconds, reads Caddy's access-log files, JSON-parses and hashes up to 5000 lines, and batch-inserts them -- all synchronous work with nothing to yield the event loop partway through. Rather than ship a fourth guess-based fix, this release adds two pieces of logging visible in the container's own logs: a warning whenever that import job takes over 500ms (broken down into read/hash/insert time), and a warning whenever any request takes over 1 second to answer. The next slow page load should show, in the logs, either the import job's duration lining up with the slow request's timestamp (confirming the suspect) or a different pattern entirely (pointing somewhere else). Both log lines are marked as temporary instrumentation, intended to be removed once the real cause is confirmed and fixed.
+
+`v0.16.45` fixes the confirmed root cause behind the multi-second page loads reported after v0.16.41-v0.16.43: the user's own container logs, captured with v0.16.44's temporary diagnostics, showed completely unrelated endpoints -- `/api/dashboard`, `/api/system/security`, `/api/logs/prune/preview` -- all finishing within moments of each other at nearly identical ~8.5-9 second durations, right after the container started. That pattern only happens when several requests are queued behind one shared blocking operation, not when each is independently slow. The culprit: `dashboardSnapshot()` (which every `/api/dashboard` fetch runs) called `storage.integrity()` -- a full `PRAGMA integrity_check`, a complete scan of the entire SQLite database file for corruption, one of the most expensive operations SQLite can run -- on every single call, purely to compute one cosmetic "Healthy"/"Needs attention" label. Because this app's SQLite queries run synchronously, that scan didn't just make its own request slow, it froze the entire single-threaded server for its whole duration, on every dashboard fetch, for every user. The fix moves that check off the request path entirely: a new `refreshDatabaseIntegrityCache()` runs the real scan once shortly after startup and then every 30 minutes in the background, caching just the resulting status string, and `dashboardSnapshot()` now reads that cached value instantly instead of re-scanning the whole database on every poll. The (rarely-used, explicitly manual) downloadable support report still runs a live, real-time integrity check, since that's an appropriate place for a slow, thorough scan. v0.16.44's temporary `[perf]` logging stays in place for this release so the fix's effect is directly visible in the container's own logs -- expect no more `[perf] GET ... took` warnings tied to `/api/dashboard` going forward.
+
+`v0.16.47` makes the page-scoped refresh button (added in v0.16.43) consistent across every view instead of appearing on most pages but not Logs, and removes a now-redundant control. The button is repositioned to always sit top-right, immediately to the right of that page's green primary action button (“+ New hosted site”, “Run certificate check”, “Refresh logs”) when one is present, or in that same top-right spot when a page has no primary action button of its own; it now also appears on the Logs page rather than being hidden there. A dedicated CSS rule (`.page-refresh{width:44px;height:44px}`) makes the button exactly the same height as the app's existing 44px primary-button standard (the same convention already used for the Backups and Retention action rows), so it visually lines up with the button beside it instead of looking undersized next to it. The Live Health panel's own separate “↻” refresh icon has been removed from the Dashboard, since the page-level refresh button sitting a few pixels away now does the identical job (`refreshDashboard()`, which repopulates that same panel); `refreshDashboard()` itself is unchanged and still runs on its normal 30-second Overview timer, it just no longer drives a second, separate icon's spinner.
+
+`v0.16.48` is a batch covering five separately-reported items. First, it fixes a real layout regression v0.16.47 introduced: reordering the header's action buttons so the page-refresh icon appeared after the green primary button caused `header`'s `justify-content:space-between` to treat every button as its own flex item and redistribute space between all of them, visibly shifting the green button ("Refresh logs", "Run certificate check", etc.) away from its usual position instead of leaving it in place with the icon simply appended beside it. The buttons are now wrapped in a single `.header-actions` container so `header` only ever splits space between the page title and that one group, and the group's own `gap` keeps its buttons hugging together at the right edge exactly as before v0.16.47. Second, it removes the temporary `[perf]` diagnostic logging added in v0.16.44 (the slow-request middleware and the `importAccessLogsToSqlite` timing breakdown), now fully superseded by v0.16.45's fix and no longer needed. Third, it removes the "Block common exploits" per-Proxy-Host toggle entirely -- its regex-based matcher only ever inspected the request path, never the query string, so it never provided the SQL-injection/XSS protection its label implied; the checkbox, its documentation entry, and every server-side and client-side reference to `blockCommonExploits` are gone. Fourth, it applies the same "cache expensive checks instead of recomputing them on every request" fix used for the database-integrity check in v0.16.45 to the System tab hero panel's disk-usage figure: when `DATA_DIR_LIMIT_GB` is set, the hero panel needs a real recursive walk of `/data` to compute its used-space percentage, and that walk was being redone on every single 7-second hero-panel poll, for every concurrent viewer. It's now computed once shortly after boot and refreshed every 60 seconds in the background (`refreshDataDirSizeCache()`), with the hot request path just reading the cached value -- deployments that don't set `DATA_DIR_LIMIT_GB` are unaffected, since they never triggered this walk in the first place. Fifth, the ROADMAP's own "What's next" section is reconciled against the "Shipped" section above it: two items it listed as upcoming (browsable backup/restore history, a Docker container picker for Proxy/Streaming targets) had already shipped and were removed from the list.
