The rest of the SharpMUTerm gap list after #29.

Changes

  • MCCP2/3: registered with TNC; answered when the server offers it. A negotiation event shows when compression starts or stops.
  • NEW-ENVIRON (MNES): answered on the server's DO with CLIENT_NAME / TERMINAL_TYPE from the client identity. Never requested unprompted.
  • MXP <SUPPORT> / <VERSION>: answered from what the parser renders (send, image and the attributes it reads), so servers don't send markup that would show stripped. MxpTags.Answer handles bare tags, tag.attr and tag.*.
  • TLS per world: "Use TLS" and "Skip certificate checks" in the world editor. The SslStream is kept and disposed with the socket; the handshake has a 20s limit. Stored as two new Worlds columns that WorldStore adds to existing databases, since the schema comes from EnsureCreated.
  • Show images from worlds setting (default on). Off renders the alt text instead of loading the remote URL.

Verification

CI on 1028879: core 296, UI 80, data 19 tests passed (from 284/77/17); Android head Release build passed. Not exercised against a live TLS or MCCP server.

Review

Own review pass plus Copilot; fixes are in 05d2214 and 1028879. Checked and not changed:

  • Overlapping SslStream writes: TNC serializes every outbound write under the interpreter's write lock, so they can't overlap.
  • EF migrations instead of the column list: a larger change than this PR; the list is fine for additive columns.
  • <SUPPORT> still lists image when images are turned off: the answer is per connection while the setting changes live. Left as a follow-up.

- SendNAWS was removed in TNC 2.8.0; report the window size through
  NAWSProtocol.SendWindowSizeAsync, clamped to RFC 1073's 0..65535
  (TNC now throws outside it instead of wrapping).
- TNC 2.8.0 stopped naming the client: TTYPE would answer UNKNOWN.
  Set WithClientIdentity("SharpClient") with TERMINAL_TYPE XTERM and
  MTTS ANSI|UTF-8|256 colours (truecolour is not rendered, so not claimed).
- Bump directly referenced Microsoft.Extensions.* to 10.0.14, the floor
  TNC 4.6.1 depends on, so restore does not report a downgrade (NU1605).
- TNC 4.0 dropped FSharp.Core, so Android Release AOT is re-enabled.
  Trimming stays off until a trimmed APK is checked on a device.

TNC drops a NAWS report made before the server's DO NAWS, as RFC 1073
requires, and nothing reported it again: the size the UI measured at
connect and the size carried over an auto-reconnect never reached the
server until the next resize. WindowSizeProtocol keeps the last size and
reports it when NAWS is agreed, the way SharpMUTerm does. The default
protocol set is spelled out because AddDefaultMUDProtocols always
registers the base NAWSProtocol.

- SGR 38;2 / 48;2 now render as the given colour (AnsiColorKind.Rgb)
  instead of the default, and MTTS claims truecolour.
- MXP <IMAGE> on a Secure line and Pueblo <img src> render as <img> in
  the output, inside a <SEND>/<a> link when one is open. Only http(s)
  and data:image URLs are accepted; images load with no-referrer.
- Pueblo is detected by TNC's PuebloProtocol (the server's hello and its
  start sequence, both consumed) instead of a substring match on any
  line, which let a player's pose switch the client into HTML mode and
  sent PUEBLOCLIENT as a game command. A server that agreed MXP stays on
  MXP, as SharpMUTerm does. MXP/Pueblo state resets when the connection
  drops, so a reconnect negotiates it again.

- MCCP2/3 and NEW-ENVIRON (MNES) are registered and answered when the
  server offers them; neither is requested unprompted.
- MXP <SUPPORT> and <VERSION> are answered from what the parser renders
  (send, image), so servers don't send markup that would show stripped.
- Worlds can connect over TLS, optionally accepting a self-signed
  certificate. The two columns are added to existing databases, since
  the schema comes from EnsureCreated.
- A "Show images from worlds" setting turns off remote image loading;
  the alt text shows instead.

Walkthrough

The changes add per-world TLS configuration and optional TLS transport, Telnet negotiation handling, and a persistent setting for inline image display. The UI exposes TLS and image settings, and tests cover their persistence and behavior.

Changes

TLS connection and Telnet negotiation

Layer / File(s) Summary
Configure and persist world TLS settings
src/SharpClient.Core/Domain/World.cs, src/SharpClient.Core/Presentation/WorldManagerViewModel.cs, src/SharpClient.Data/WorldStore.cs, src/SharpClient.UI/Components/WorldEditor.razor, tests/SharpClient.Data.Tests/WorldStoreTests.cs, tests/SharpClient.UI.Tests/WorldEditorTests.cs
Worlds now store TLS and invalid-certificate settings. The editor exposes these options, and the store adds missing TLS columns with a default of 0. Tests cover saving, loading, and compatibility with databases that lack the columns.
Apply TLS settings to the connection
src/SharpClient.Core/Connection/ITelnetConnection.cs, src/SharpClient.Core/Connection/TelnetConnection.cs, src/SharpClient.Core/Sessions/TelnetSessionLauncher.cs, tests/SharpClient.Tests/Connection/TlsConnectionTests.cs, tests/SharpClient.Tests/Sessions/FakeTelnetConnection.cs
The launcher applies world TLS settings to the connection. When TLS is enabled, the connection authenticates an SslStream with a 20-second timeout and applies the configured certificate policy. Cleanup releases the stream and client. Tests cover acceptance and rejection of a self-signed certificate.
Handle Telnet protocol negotiations
src/SharpClient.Core/Rendering/MxpTags.cs, src/SharpClient.Core/Connection/TelnetConnection.cs, tests/SharpClient.Tests/Rendering/MxpTagsTests.cs, tests/SharpClient.Tests/Connection/ProtocolAnswerTests.cs
MxpTags classifies supported MXP tags and attributes. The interpreter registers MCCP and NEW-ENVIRON and handles MXP support and version requests. Tests cover the MXP responses and Telnet negotiation behavior.

Inline image display setting

Layer / File(s) Summary
Persist and apply the image display setting
src/SharpClient.Core/Presentation/SettingsViewModel.cs, src/SharpClient.UI/Components/SettingsView.razor, src/SharpClient.UI/Components/SessionScreen.razor, src/SharpClient.UI/Components/OutputView.razor, tests/SharpClient.Tests/Presentation/SettingsViewModelTests.cs, tests/SharpClient.UI.Tests/OutputViewLinkTests.cs
ShowImages defaults to true and persists preference changes. The settings view exposes a checkbox, and OutputView renders image segments as images only when the setting is enabled. Tests cover preference persistence and hidden-image rendering.

Estimated code review effort: 4 (Complex) | ~45 minutes

Docstring coverage is 13.64% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 22 functions across 16 files. (4 skipped: 4 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Keep the SslStream and dispose it with the socket on disconnect,
  reconnect and failed connects (a failed build used to leak both).
- Give the TLS handshake a 20s limit so a port that never answers the
  ClientHello can't hold a connect or reconnect attempt forever.
- Tolerate "duplicate column name" when two stores upgrade the same
  database at once.
- MxpTags: one table of tags and attributes instead of two lists.

- "Show images from worlds" is now a label so the checkbox has a name.
- The certificate option says it skips all checks, which is what it does.
- The MXP VERSION test waits for the closing '>' it asserts on.
