feat(http): the card is the default curl report

The classic report is 125 columns wide, so in a normal terminal window
every row wrapped and the frames fell apart. A request with no view now
gets the card, 64 columns wide. The classic report stays one parameter
away (?view=v1), and options only it understands (0-3, n, days=) or a PNG
still select it. The BBS keeps the classic report when a tool call names
no view.

Along the way:
- the card's title comes from the geocoder ("São Paulo, Brasil", "Tour
  Eiffel, France") instead of the lower-cased query or bare coordinates
- the rain column is padded, so "9%" no longer shifts the wind column
- in the browser each emoji takes exactly two cells, as in a terminal,
  so framed rows keep their right border in line
- help page and README describe the new default

Pablo Murad

feat(http): curl reports dressed as the BBS

Framed reports (v1, v2, v2d, v2n, card) now come out in Hammer's look: a
"HAMMER" header, double-line frames in the retro palette, and a footer
with the tagline and the command that opens the BBS, taken from the new
brand block of the configuration (brand.ssh; empty drops it). ?F drops
the footer, ?Q drops header and footer, ?T and ?d behave as before. The
BBS itself renders directly and is not dressed.

Terminals disagree about how wide an emoji is, which pushed the right
border of card and v2 rows out of line. Those rows now move the cursor to
the frame's last column (CSI n G) before drawing the border.

Help pages name this host (brand.host) instead of the upstream one.

Long forecast descriptions in v1 are cut at a word ("Patchy rain…"
rather than "Patchy rain ne…"), and one that fits exactly no longer gets
an ellipsis it does not need.

README: independent status line, "How reports look", credits point to the
new NOTICE, which keeps the attribution the Apache licence asks for.

Pablo Murad

refactor: Hammer stands on its own

Removes what still spoke for the project Hammer grew out of:

- translations: the upstream author's "Follow" footer and two unused
  strings that advertised the upstream service, in every language; his
  name from the translator credits (the volunteers stay)
- web page: our title, no third-party social buttons or their scripts
- translation page and bash helper: our names, no upstream contacts
- sample config: /hammer paths instead of the upstream's
- dead files: the SaltStack and systemd recipes for the upstream host, a
  lolcat wrapper with the upstream author's home path, and an orphan HTML
  page the static handler would still serve

Also fixes a trailing comma in the crk translation metadata.

Pablo Murad

style: centre the splash prompt and chat title, brighter retro hotkeys

Found in screenshots of real sessions: the splash's "press any key" sat at
column 0 under centred art, the chat's title and hint did not line up with
the art above them, and the retro theme's dark blue hotkey brackets were
nearly invisible on a dark background (now light blue).

Pablo Murad

feat(bbs): themes per session, ANSI art on screen, modem effect

Every interactive session now picks its theme from the profile (or
bbs.style.defaultTheme, retro90 by default) at the colour level its
terminal reports, and the art shows up:

- splash: the Hammer piece at modem speed (bbs.style.baud, 9600 by
  default), credited from its SAUCE record; any key finishes the drawing
- wall, chat, weather, tools and settings: header art above the menu when
  the terminal is wide and tall enough
- goodbye: NO CARRIER, then "see you"
- narrower than 80 columns, or no colour: text titles, no art

Input is now read by a goroutine per session and handed to nextByte over
a channel, so a screen can check for a key without blocking; this is what
lets a keypress cut the modem effect short.

A status bar pins "nick · N online · theme · connected for" to the last
row of menu screens. Settings gains theme and modem-effect entries,
saved in the profile. Dumb terminals get the plain theme: ASCII boxes, no
colour codes and no cursor movement.

README gains a Look and feel section; deploy configs gain bbs.style;
.gitattributes marks .ans files as binary.

Pablo Murad

fix(profiles): saving a profile with a nickname lost every change

Save tried an INSERT first and fell back to UPDATE on a unique-constraint
error. Once profiles had nicknames, SQLite reported the nickname index
before the primary key when re-saving an existing profile, Save read that
as "nickname taken", and returned without updating. Units, language,
cities and every other setting of a keyed user silently stopped being
saved.

Save now updates an existing row and inserts only new ones; a nickname
conflict is reported only when another key really holds the name. A
regression test re-saves a profile with its own nickname unchanged.

The profiles table also gains theme and fx columns (same in-place
migration as nick) for the look-and-feel settings that follow.

Pablo Murad

feat(art): Hammer's own ANSI art

Seven pieces drawn from scratch for the BBS, saved as real .ans files
(CP437, iCE colours, SAUCE credited to hammer / hammer bbs) that open in
PabloDraw and Moebius:

- splash: HAMMER in steel-and-ice block letters with a drop shadow, a
  hammer struck by lightning, the tagline and art-pack shade bars
- wall: THE WALL over a brick wall
- chat: speech bubbles
- weather: sun behind a rain cloud
- tools: open-end spanner and screwdriver
- setup: mixing-desk sliders
- nocarrier: NO CARRIER over a modem front panel with CD gone dark

They are drawn by tools/artgen (go generate ./internal/bbs) on a pixel
layer at two pixels per cell (▀ ▄ █), with a chunky block font, gradients
and shadows. artgen -png renders previews through the same loader the BBS
uses. Third-party art can join them as plain .ans files, with the
author's permission.

Pablo Murad

feat(ansiart): load and render classic ANSI art

A package for .ans files as the art scene makes them:

- SAUCE records are parsed (title, author, group, date, width, iCE flag)
  and stripped with their COMNT block and the ^Z marker.
- CP437 is decoded to Unicode; files already in UTF-8 pass through.
- The file is played on a virtual 80-column terminal (go-te, already a
  dependency), so cursor movement, wrapping, bold-as-bright and
  blink-as-bright-background land where the artist put them.
- Render emits the art in any 16-colour palette at the terminal's colour
  level (truecolor, 256, 16 or none), leaving black backgrounds to the
  terminal, and Credit builds the attribution line from SAUCE.

Canvas draws a grid and encodes it as a real .ans file (CP437, iCE colours,
CRLF, SAUCE), which is how Hammer's own art is produced.

Pablo Murad

refactor(ui): themes instead of fixed colours

The BBS palette lived in constants, so there could only ever be one look.
A Theme now carries the colour roles, box glyphs, title decoration, block
shadow, hotkey style, menu leader and the 16-colour palette ANSI art is
drawn with:

- retro90: VGA palette, double-line boxes with block shadows, blue
  brackets around hotkeys, dotted leaders in menus
- modern: rounded boxes, a softer palette and gradient titles on
  truecolor terminals
- plain: ASCII boxes and no escape sequences, for dumb terminals

Colour is emitted at the level the terminal supports (truecolor, 256,
16, none), detected from TERM and COLORTERM.

Every screen in the bbs package now paints through the session's theme
(st.th); menuEntry, settingsEntry, wallLine and colorNick became session
methods. Sessions still use the modern theme at 256 colours, so nothing
changes visibly yet; picking the theme comes later.

Pablo Murad

feat(dispatch): who, wall and wall.post; document the community

Scripts and agents can now see who is online (`who`), read the wall
(`wall count=N`) and post to it (`wall.post text="..."`). Posting needs a
key and honours the same cooldown and bans as the menu; a cooldown comes
back as rate_limited with retry_after. The chat stays interactive only.

README: a Community section (nicknames, who's online, wall, chat,
moderation, anonymous read-only) and the bbs.community block in the
configuration example. Runbook: how to make your key a moderator.

Pablo Murad

feat(bbs): wall, who's online and live chat screens

Main menu: the title shows how many people are online, the latest
one-liners sit above the menu the way a BBS greets you with its wall, and
two new entries open the wall [w] and the chat [c].

Wall: the latest lines from everyone with their age and a colour per
nickname; post (keys only, with the per-key cooldown), see who is online
(where they are, for how long, how many connections), and, for
moderators, delete a line by number.

Chat: messages scroll above an input line that stays put. The session
goroutine owns input and a receiver goroutine draws incoming messages;
both write under the session's write lock and the receiver redraws the
line being typed after each message. Long input scrolls sideways so one
erase always clears it. Commands: /help /who /me /nick /quit, and for
moderators /mute /kick /ban /unban. Anonymous visitors read but cannot
talk. Ctrl+C leaves the room, not the BBS. `ssh -t host chat` opens the
room directly.

System events (joins, kicks, renames) are rendered in each reader's
language. End-to-end tests drive several real SSH clients: messages
crossing between people, escape sequences stripped, flood limit,
read-only anonymous, moderator kick, wall cooldown and the online list.

Pablo Murad

feat(bbs): nicknames and community settings

Every key now has a nickname, unique regardless of case:

- New keys get their SSH user name (ssh pablo@host -> pablo) when it is
  meaningful and free, otherwise guest-xxxx, widened until free.
- Profiles saved before nicknames get one on their next login; the
  profiles table gains a nick column through an in-place migration.
- Settings has a nickname entry with validation (2-16 characters,
  reserved names refused) and a friendly message when it is taken.
- Anonymous sessions get a guest name that is never stored.

The unique index is on the column with COLLATE NOCASE rather than an
expression: godb's SQLite error parser panics on the message an
expression index produces.

A new bbs.community block configures moderators (key fingerprints), the
wall (lines shown, length, cooldown) and the chat (length, rate). The
server builds the presence tracker, wall and chat hub on the profiles
database.

Pablo Murad

feat(community): presence, one-liner wall and chat hub

A terminal-free package for the social side of the BBS:

- CleanText strips escape sequences (CSI, OSC and the rest), C0/C1
  controls and bidi overrides from anything one user shows another, and
  cuts it to a width in terminal cells.
- Nickname rules, reserved names and guest-xxxx fallbacks.
- Presence: who is online, one entry per key, in memory.
- Wall: the last one-liners from everyone, a per-key cooldown and pruning,
  stored in the BBS's SQLite database.
- Hub: a chat room with a 100-message in-memory history, per-key rate
  limit, a bounded queue per member so a slow reader never blocks the room,
  read-only anonymous members, and moderation (mute, kick, ban, unban) with
  bans persisted and honoured by the wall too.

Pablo Murad

refactor(bbs): split session.go by responsibility, thread-safe writes

session.go had grown to ~1,200 lines mixing terminal I/O, the main menu,
weather and settings. It is now:

- session.go: connection lifecycle, identity, splash, main loop
- session_io.go: input, output and screen primitives
- menu_main.go, menu_weather.go, menu_settings.go: the menus

Functions moved verbatim. The one change in behaviour: writes to the SSH
channel and the session error they record are now guarded by a mutex
(wmu), with writeLocked for compound updates. This is groundwork for the
chat, where incoming messages are drawn from another goroutine while the
user types. Existing tests pass unchanged.

Pablo Murad

feat: NDJSON dispatcher, SFTP area, async jobs

SSH: one port now answers three ways. An interactive terminal gets the
menu; a command (`ssh host hash input=hi`) or a pipe with no terminal gets
a newline-delimited JSON dispatcher over a closed vocabulary with declared,
validated arguments; the sftp subsystem gets a private per-key file area
that tools read with file=NAME. Slow tools (net, links, data, path) can run
as background jobs (async=true, then `job id=...` from any connection with
the same key). Jobs live in memory.

Anonymous sessions are now throwaway identities: defaults for the
connection, nothing saved, no file area. Keying them by client IP made
everyone behind one NAT share and overwrite each other's settings.

HTTP: X-Forwarded-For / X-Real-IP are believed only from trusted proxies
(server.trustedProxies, loopback by default), read right to left. Weather
requests are rate limited per client IP (429 + Retry-After), dispatcher
calls per key, and geocoder calls per UTC day (geo.dailyLookupLimit) to
protect the OpenCage quota.

OCR is removed everywhere: ocrpdf package, menu entry, config keys,
translations and the ocrmypdf/tesseract packages in the Dockerfile. Old
configs carrying ocr* keys will fail at startup; use the ones in deploy/.

The storage purge is generalised to the file area (sweepStorageLoop).
Tests added for the HTTP server, client IP resolution, rate limiting,
dispatcher, jobs, file area and the SSH modes end to end. README and the
CloudPanel runbook describe the current ports, modes and limits, and
`make go-test-zig` runs the cgo tests without a C compiler.

fix(renderer): v2 crashes and mis-drawing, plus test suite

The v2 panel crashed on ordinary inputs and drew several things wrong.

Crashes fixed:
- location names over ~52 characters (negative strings.Repeat); the
  caption is now cut with an ellipsis and measured in terminal cells
- interpolate: infinite recursion on 2 points, NaN spline on width 1
- temperature diagrams with a single data point (division by zero)
- rain sparkline narrower than its label, or series shorter than width
- invalid timezone in drawDate, nil Options/Location in Render
- negative wind bearings and fewer speeds than directions

Drawing fixed:
- daylight timeline was never drawn and started at UTC midnight; it now
  follows the sun's elevation from local midnight (covers polar day/night)
- frame padding counted bytes, so rows with colour or accents were ragged
- caption flags: quiet drops the prefix, no-city drops the city
- spline overshoot showed temperatures never forecast and negative rain;
  interpolation is now clamped to the input range
- emoji and wind rows are resampled to the 24 panel slots

oneline: the plain emoji profile declared up-to-3-character symbols as
one cell wide, and GetEmojiProfile dereferenced a nil options pointer.

Adds a v2 test suite (99% coverage) with a regression test per fix.

Remove GitHub URL from splash and about screens

The project repository link no longer appears on the interactive front-end.
Drops the attributionURL line from the splash and the about screen, and the
now-unused constant. Author attribution and the pablomurad.com invite footer
stay.

fix(deploy): docker prod compose, config and runbook

Pablo Murad

chore(deploy): add deployment configs and CloudPanel runbook

- deploy/config.yaml: production config (BBS SSH + HTTP weather, ${VAR} secrets)
- deploy/hammer.service: systemd unit (dedicated user, CAP_NET_BIND_SERVICE for :22)
- deploy/nginx-hammer.conf: reverse proxy for the HTTP weather service
- deploy/DEPLOY-CLOUDPANEL.md: step-by-step runbook for the CloudPanel VPS
  (web via reverse proxy -> 8080, SSH BBS direct on 2323)
- .env.example: document GEOLITE2_LICENSE_KEY, symbolic placeholders

Pablo Murad

docs: remove doc/ folder

Pablo Murad

feat: SSH tools platform, i18n, and build/port/format fixes

- BBS front-end: interactive menu, per-key profiles, tool dispatcher
- Native tools: net, qr, hash, jq, age, csv, b64, ids (+ optional links, data, path, ocr)
- i18n for the BBS menu across all bundled languages
- Move BBS SSH port 2222 -> 2323 (2222 already in use; 22 disallowed)
- gofmt: reformat cache, ip, location, logging and v2 renderer files
- Re-enable the gofmt linter in .golangci.yaml so formatting is enforced
- build.sh: fail the build when no fonts are embedded, and warn on partial
  font sets, to avoid silently shipping a binary with degraded PNG output

Pablo Murad

Add .env support and fix startup panics for minimal configs

Pablo Murad

Add emoji weather card and redesign the BBS UI
