5 people	75cecd9803	feat: implement hashcash proof-of-work for session creation (#63) ... ## Summary Implement SHA-256-based hashcash proof-of-work for `POST /session` to prevent abuse via rapid session creation. closes sneak/chat#11 ## What Changed ### Server - **New `internal/hashcash` package**: Validates hashcash stamps (format, difficulty bits, date/expiry, resource, replay prevention via in-memory spent set with TTL pruning) - **Config**: `NEOIRC_HASHCASH_BITS` env var (default 20, set to 0 to disable) - **`GET /api/v1/server`**: Now includes `hashcash_bits` field when > 0 - **`POST /api/v1/session`**: Validates `X-Hashcash` header when hashcash is enabled; returns HTTP 402 for missing/invalid stamps ### Clients - **Web SPA**: Fetches `hashcash_bits` from `/server`, computes stamp using Web Crypto API (`crypto.subtle.digest`) with batched parallelism (1024 hashes/batch), shows "Computing proof-of-work..." feedback - **CLI (`neoirc-cli`)**: `CreateSession()` auto-fetches server info and computes a valid hashcash stamp when required; new `MintHashcash()` function in the API package ### Documentation - README updated with full hashcash documentation: stamp format, computing stamps, configuration, difficulty table - Server info and session creation API docs updated with hashcash fields/headers - Roadmap updated (hashcash marked as implemented) ## Stamp Format Standard hashcash: `1:bits:YYMMDD:resource::counter` The SHA-256 hash of the entire stamp string must have at least `bits` leading zero bits. ## Validation Rules - Version must be `1` - Claimed bits ≥ required bits - Resource must match server name - Date within 48 hours (not expired, not too far in future) - SHA-256 hash has required leading zero bits - Stamp not previously used (replay prevention) ## Testing - All existing tests pass (hashcash disabled in test config with `HashcashBits: 0`) - `docker build .` passes (lint + test + build) <!-- session: agent:sdlc-manager:subagent:f98d712e-8a40-4013-b3d7-588cbff670f4 --> Co-authored-by: clawbot <clawbot@noreply.git.eeqj.de> Co-authored-by: clawbot <clawbot@noreply.eeqj.de> Co-authored-by: user <user@Mac.lan guest wan> Co-authored-by: Jeffrey Paul <sneak@noreply.example.org> Reviewed-on: sneak/chat#63 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>	2026-03-13 00:38:41 +01:00

3 people	946f208ac2	feat: implement IRC numerics batch 2 — connection registration, channel ops, user queries (#59) ... ## Summary Implements the remaining important/commonly-used IRC numeric reply codes, as requested in [issue #52](sneak/chat#52). ### Connection Registration (001-005) - **002 RPL_YOURHOST** — "Your host is <server>, running version <ver>" - **003 RPL_CREATED** — "This server was created <date>" - **004 RPL_MYINFO** — "<server> <version> <usermodes> <chanmodes>" - **005 RPL_ISUPPORT** — CHANTYPES=#, NICKLEN=32, CHANMODES, NETWORK=neoirc, CASEMAPPING=ascii All sent automatically after RPL_WELCOME during session creation/login. ### Server Statistics (251-255) - **251 RPL_LUSERCLIENT** — user count - **252 RPL_LUSEROP** — operator count - **254 RPL_LUSERCHANNELS** — channel count - **255 RPL_LUSERME** — local client count Sent during connection registration and available via LUSERS command. ### Channel Operations - **MODE command** — query channel modes (324 RPL_CHANNELMODEIS + 329 RPL_CREATIONTIME) and user modes (221 RPL_UMODEIS) - **NAMES command** — query channel member list (reuses 353/366) - **LIST command** — list all channels with member counts (322 RPL_LIST + 323 end) ### User Queries - **WHOIS command** — 311 RPL_WHOISUSER, 312 RPL_WHOISSERVER, 319 RPL_WHOISCHANNELS, 318 RPL_ENDOFWHOIS - **WHO command** — 352 RPL_WHOREPLY, 315 RPL_ENDOFWHO ### Database Additions - `GetChannelCount()` — total channel count for LUSERS - `ListAllChannelsWithCounts()` — channels with member counts for LIST - `GetChannelCreatedAt()` — channel creation time for RPL_CREATIONTIME - `GetSessionCreatedAt()` — session creation time ### Other Changes - Added `StartTime` to `Globals` struct for RPL_CREATED - Updated README with comprehensive documentation of all new commands and numerics - Updated roadmap to reflect implemented features `docker build .` passes (lint, tests, build all green). closes [#52](sneak/chat#52) <!-- session: agent:sdlc-manager:subagent:1f3dcab8-ad6a-4c4c-af72-34a617640c9d --> Co-authored-by: clawbot <clawbot@noreply.git.eeqj.de> Co-authored-by: clawbot <clawbot@git.eeqj.de> Reviewed-on: sneak/chat#59 Co-authored-by: clawbot <sneak+clawbot@sneak.cloud> Co-committed-by: clawbot <sneak+clawbot@sneak.cloud>	2026-03-10 00:53:46 +01:00
clawbotanduser	47fb089969	fix: IRC SPA cleanup — /motd, /query, Firefox / key, default MOTD (#58) ... ## Summary Fixes IRC client SPA issues reported in [issue #57](sneak/chat#57). ## Changes ### Server-side - **Default MOTD**: Added figlet-style ASCII art MOTD for "neoirc" as the default when no MOTD is configured via environment/config - **MOTD command handler**: Added `MOTD` case to `dispatchCommand` so clients can re-request the MOTD at any time (proper IRC behavior) ### SPA (web client) - **`/motd` command**: Sends MOTD request to server, displays 375/372/376 numerics in server window - **`/query nick [message]`**: Opens a DM tab with the specified user, optionally sends a message - **`/clear`**: Clears messages in the current tab - **Firefox `/` key fix**: Added global `keydown` listener that captures `/` when input is not focused, preventing Firefox quick search and redirecting focus to the input element. Also auto-focuses input on SPA init. - **MOTD on resumed sessions**: When restoring from a saved token, the MOTD is re-requested so it always appears in the server window - **Updated `/help`**: Shows all new commands with descriptions - **Login screen MOTD styling**: Improved for ASCII art display (monospace, proper line height) ## Testing - `docker build .` passes (includes `make check` with tests, lint, fmt-check) - All existing tests pass with no modifications closes #57 <!-- session: agent:sdlc-manager:subagent:7c880fec-f818-49ff-a548-2d3c26758bb6 --> Co-authored-by: user <user@Mac.lan guest wan> Reviewed-on: sneak/chat#58 Co-authored-by: clawbot <clawbot@noreply.example.org> Co-committed-by: clawbot <clawbot@noreply.example.org>	2026-03-09 23:00:34 +01:00
