Steps 5 and 6 of docs/adding-hosts-on-the-phone.md, which finishes it. The phone can now put things in a keychain rather than only read one. The floating + arrives three designs after it was first asked for. It was refused twice on the honest grounds that it would open an editor this head had not got — and that stopped being true when steps 1 to 4 landed. It raises a sheet rather than a form, because "add" on this screen has been two operations since groups existed: a host, or a group to file hosts under. Both editors are cards in the list's own row, swapped for the list rather than stacked over it, following SnippetsScreen and for the reason written there: a form on top of the list hides what it is about. There is still no dialog and no editor screen anywhere on this head. The port and username boxes may be left empty, and the greyed text inside each is what the host will actually use — following the group picker as it moves, so the form says what leaving a box blank will do rather than making it a guess. The back gesture gains a guard above the switch rather than a case inside it. An editor is not a screen and has no entry there, and it is strictly nearer: the sheet sits over the editor's own screen, so back lowers whatever is topmost before it considers moving between screens. A group editor needs a way in, and the phone draws no groups panel — so the heading in the host list gains a pencil. A + that adds groups with no way to correct one is the same strange thing to ship as one that adds hosts with no way to correct one, and worse: a group's defaults are what every host beneath it falls back to. Scouting step 6 turned up a bug worth more than the prose it was looking for. ReloadGroupsAsync read the active vault alone, which was a cosmetic limitation while a group carried only a name — a teammate's host showed under UNGROUPED and nothing else was lost. Since a group began lending a port, a username and a binding, the same omission silently dropped all three: that host would dial 22 as nobody while the machine is on 2222 as deploy, with nothing on screen saying why. The resolution map now spans every readable vault. The editable list stays narrow, because a row shown across vaults needs a vault id for rename and delete and two vaults may hold groups with one name — but the map needs none of that, since it is only ever asked what an id says. An adversarial review of this change found something I had written a comment denying. The + was a child of the outer Panel rather than of the list's row, so it anchored to the bottom of the screen and sat squarely over the new EDIT button and the lower edge of CONNECT — and because a Panel hit-tests its last-declared child first, tapping the right end of EDIT would have raised the add sheet. The comment beside it claimed it was in the list's row precisely so that could not happen, and manual-checks 8.1 names that exact failure. It is in Grid.Row 2 now. The same pass caught a connect bar that was disabled rather than hidden while its own comment said hidden, a scrim that would have flashed its default pressed chrome across the screen, a fab comment claiming an accent fill no other button had when Button.primary has it, and a back-gesture remark naming two view-model properties that do not exist anywhere in the repo. That last one came from this plan, which invented IsVaultsSurface and IsConnectionsSurface, and pointed step 6 at a ConnectionsScreen.axaml that has never existed. Both are corrected in the plan rather than quietly worked around, along with a fourth "groups are flat" site in README.md that step 1 missed. The phone's rectangles are not measurable and structurally never will be: the layout suite is net10.0, the Android head is net10.0-android, and Avalonia's application is a one-shot process global — so a second head cannot share the process even if the reference were possible. Everything the sheet and both editors bind to is shared and is tested headlessly here; the pixels go to docs/manual-checks.md phase 8, nine checks, which is where this project already sends what it cannot assert. Tags remain the one thing asked for that did not ship. Tag is a full item kind and TagIds merges, encodes and resolves, but no screen draws a chip or offers to add one, so the tags a client can store are ones nothing here can see. Both editors carry the set through a save untouched so a client that can set them does not lose them. Recorded as half-shipped in docs/design-import-gaps.md rather than quietly left out. Verified by the whole suite: 1402 tests over nineteen projects, none failing. Both heads build. Nothing seen on a display — phase 8 is what that costs.

# Adding hosts on the phone
|
||
|
||
The phone can read a keychain and connect through it. It cannot put anything in one. This document is the
|
||
plan for the change that fixes that, and it is written to be picked up cold — the decisions, the reasons, the
|
||
ordered work, and the traps that are already known.
|
||
|
||
> **Status: built.** All six steps. Each one compiled with the whole suite green before the next began,
|
||
> which is the rule the ordering below sets.
|
||
>
|
||
> | Step | State | Notes |
|
||
> | --- | --- | --- |
|
||
> | 1. `HostGroupSecret` grows | **Done** | Five fields, a version rule the codec did not have, a byte pin, and the "groups are flat" prose rewritten in all four places it appeared. |
|
||
> | 2. The `Tag` item kind | **Done** | Secret, codec, merge, cipher, repository, both registries, EF entity and the generated `AddTagItem` migration. |
|
||
> | 3. `HostSecret` grows, `Port` goes nullable | **Done** | `TagSet`, `TagIds`, `Port` as `int?`, `AsksForPassword`, both schema versions, and `HostInheritance` — the resolver. |
|
||
> | 4. The shared view model | **Done** | Every choke point below, plus the group editor the plan never assigned a step to and without which nothing could set a default at all. |
|
||
> | 5. The phone | **Done** | The `+`, the sheet, both editor cards, the back guard and EDIT on the connect bar. |
|
||
> | 6. Tests and false prose | **Done** | Plus a fourth "groups are flat" site in `README.md` this plan did not list, and a cross-vault resolution bug the scouting for it turned up. |
|
||
>
|
||
> **Tags are stored and still not editable, and that is the one thing asked for that did not ship.** `Tag` is
|
||
> a full item kind and `HostSecret.TagIds` merges, encodes and resolves — but no screen on either head draws
|
||
> a chip or offers to add one, so the tags a client can store are ones nothing here can see. Both editors
|
||
> carry the set through a save untouched, so a client that can set them does not lose them to somebody
|
||
> editing a port. What is missing is a picker and a chip row, on both heads: the plan's step 5 list does not
|
||
> mention them, and building the sheet, both editors and the back guard was already the larger half of it.
|
||
> Recorded as half-shipped in `docs/design-import-gaps.md` rather than quietly left out.
|
||
>
|
||
> **`HostFields.From` was answered by a refusal rather than by threading the resolver into the sync engine.**
|
||
> A relay host may not inherit its port; `HostSecret.TryValidate` refuses one that tries. A plaintext column
|
||
> derived from a *different* item goes stale when that item is edited and nothing re-pushes the hosts beneath
|
||
> it, so the relay would keep dialling the old port — which is worse than the restriction.
|
||
>
|
||
> **One decision was taken that this plan did not specify.** "Three states where there were two" is four, not
|
||
> three: a host can bind a key, bind a credential, be pinned to a typed password, or take its group's answer,
|
||
> and two nullable ids express three of those. Naming neither id now means *inherit*, so
|
||
> `HostSecret.AsksForPassword` was added to say "a typed password, even under a group that lends a key" out
|
||
> loud. Nothing stored changed meaning — no group could lend a binding before this build, so every existing
|
||
> host resolves exactly as it did.
|
||
|
||
## What was asked for
|
||
|
||
A floating `+` at the bottom right of the phone's HOSTS screen, opening a menu at the bottom offering **new
|
||
host** or **new group**.
|
||
|
||
A **host** carries: which vault it is filed into (personal or a team's), an alias, a hostname or IP address, a
|
||
group, tags, an SSH port, and a username with either a password or an SSH key.
|
||
|
||
A **group** carries: an alias, an optional parent group, and a default SSH port, username and
|
||
password-or-key — **defaults for the hosts inside it**.
|
||
|
||
## The shape of the problem
|
||
|
||
Three of those fields do not exist at any layer, and one of them is refused on the record.
|
||
|
||
| Asked for | What exists today |
|
||
| --- | --- |
|
||
| The `+` and the editors behind it | Nothing. `Theme/Phone.axaml` has no `.fab` class, and its comment says an unused style would be "a claim that the control exists somewhere". `HostsScreen.axaml`'s own v2 note says hosts are created on the desktop and sync down. *(This row named a `ConnectionsScreen.axaml` as a second site. No such file exists or ever has; and the `HostsScreen` statement is an XAML comment, so no phone screen ever rendered that sentence to a user.)* |
|
||
| Vault picker | **Built.** `VaultViewModel.TargetVaults` / `SelectedTargetVault` / `HasVaultChoice`, hidden at one vault. The desktop's `VaultScreen.axaml` already draws it. |
|
||
| Alias, hostname, port, username, key-or-password, group | **Built**, in the shared `VaultViewModel` host editor — `EditorLabel`, `EditorHostname`, `EditorPort`, `EditorUsername`, `EditorAuthenticationChoices`, `EditorGroupChoices`, `SaveHostCommand`. The phone has never bound any of it. |
|
||
| Tags | **Nothing.** `SyncEntityType.Tag = 5` and `HostTag = 6` are reserved slots with nothing behind them. `HostSecret` has no tag field. |
|
||
| A group's parent | **Refused on the record.** `HostGroupSecret`'s own remark says groups are flat because two clients can each re-parent A under B and B under A offline, a scalar merge accepts both, and the result is a cycle no reader can draw and the server cannot see, because it is inside the payload. |
|
||
| A group's defaults | **Nothing.** `HostGroupSecret` has exactly one field, `Label`. |
|
||
|
||
So the phone half is mostly wiring. The domain half is three new capabilities, and one of them overturns a
|
||
written decision.
|
||
|
||
## The three decisions
|
||
|
||
**Tags are a real vault item, and a host names them.** A tag is a shared, reusable thing — the point of it is
|
||
to put the same tag on twenty machines and filter by it later — so it needs an identity of its own, not a
|
||
string repeated inside twenty payloads. `SyncEntityType.Tag = 5` becomes a live item kind. Membership is a
|
||
`TagIds` set on `HostSecret`, **not** the reserved `HostTag = 6` join.
|
||
|
||
The reason to skip the join is that the merge does not need it. The argument for `HostSecret.GroupId` living on
|
||
the host is that filing two hosts into one group must be two writes to two items; the same holds here. What a
|
||
join would have bought beyond that is two machines tagging *the same* host without one of them losing — and
|
||
`ThreeWayMerge.Map` already gives that. It resolves a keyed collection key by key, honouring presence and
|
||
absence, which is set semantics with removals. `HostOptions` is merged through it today via `ToNameMap()`, and
|
||
a tag set keyed by tag id is the same shape. So `HostTag = 6` stays reserved and unused, and the second run
|
||
through the item-kind checklist is not spent.
|
||
|
||
**Group defaults are inherited, not copied.** A host that leaves a field blank uses its group's value; a host
|
||
that fills one in overrides it. The editor shows the group's value as the field's placeholder, so the form
|
||
says what leaving it blank will get you. Copying the values into the host at create time was the alternative
|
||
and it was rejected: it makes a group a one-shot template rather than a live default, and changing a group
|
||
would then leave every host that had ever been created under it pinned to the old value.
|
||
|
||
**Groups get a parent, and the resolver breaks cycles.** `HostGroupSecret` gains `ParentId`. The editor refuses
|
||
a parent that is already a descendant, which stops a cycle being made here; the resolver walks with a visited
|
||
set and stops at a repeat, which contains a cycle that arrives from somewhere else. A cycle therefore degrades
|
||
to a group that reads as a root — flat headings, defaults unresolved past that point — instead of hanging the
|
||
connect path, and clearing the parent in the editor is the repair. **This is the load-bearing part of the
|
||
decision:** with inheritance the chain is walked at connect time, so an unguarded cycle is not an undrawable
|
||
sidebar, it is a shell that never opens.
|
||
|
||
`HostGroupSecret`'s "No parent. Groups are flat." remark and `HostGroupSecretTests`' class remark both become
|
||
false prose and must be rewritten to say what replaced the argument, not deleted. Same for the four rows in
|
||
`docs/design-import-gaps.md` recording the phone's missing `+`.
|
||
|
||
## What the payload becomes
|
||
|
||
```
|
||
HostSecret HostGroupSecret
|
||
Label Label
|
||
Hostname ParentId ← new, optional
|
||
Port int? — null inherits DefaultPort ← new
|
||
Username null inherits, "" none DefaultUsername ← new
|
||
Notes DefaultSshKeyId ← new
|
||
JumpHostIds DefaultCredentialId ← new
|
||
Options
|
||
SshKeyId null inherits TagSecret
|
||
CredentialId null inherits Label
|
||
AsksForPassword ← new, true only
|
||
GroupId null = ungrouped
|
||
TagIds ← new
|
||
RelayEnabled
|
||
```
|
||
|
||
`Port` becoming `int?` is the change with the widest blast radius, and it is unavoidable: `int` with a default
|
||
of 22 has no way to say "I have no port of my own". `HostSecret.DefaultPort = 22` stays, as the last fallback
|
||
after the chain runs out.
|
||
|
||
### Three states where there were two
|
||
|
||
`SshKeyId` and `CredentialId` both null currently *means* "ask for a password each time" — a decision, not an
|
||
absence. `AuthenticationChoice`'s own remark argues at length that the two must never be conflated.
|
||
Inheritance adds a state, so the picker needs an explicit **"Inherit from group"** entry beside **"Password
|
||
(ask each time)"**, and `Bound(...)` needs to distinguish them. `Username` has the same problem: null means
|
||
"no username" today and is refused at connect; it has to come to mean "inherit", with "no username" still
|
||
reachable and still refused.
|
||
|
||
**Built as four states, not three, because two nullable ids only carry three.** Key, credential, typed
|
||
password, inherit — and naming neither id was the third and is now the fourth. `HostSecret.AsksForPassword`
|
||
carries the difference: null is "not stated", which walks the chain and lands on a typed password if the
|
||
chain lends nothing, and `true` is "a typed password, even under a group that lends a key". Only `true` is
|
||
ever written, and a decoded `false` folds back to null, so a host that never touched the field encodes
|
||
exactly as it did before it existed. `Username` needed no field — an empty string is "no username" and null
|
||
is "inherit". `Port` needed none either: there is no "explicitly no port", only 22 at the end of the chain.
|
||
|
||
Mutual exclusion moves with it. `HostSecret.TryValidate` enforces "a key or a credential, never both" per
|
||
record; a host naming a credential under a group naming a key is two individually valid records that resolve to
|
||
two bindings. **Exclusion has to be enforced at resolution**, host-over-group, and the resolver must never
|
||
return both.
|
||
|
||
## The order to build it in
|
||
|
||
Each step compiles and its tests pass before the next one starts. Steps 1–3 are the domain and are
|
||
prerequisites for everything; step 4 is the only user-visible one.
|
||
|
||
### 1. `HostGroupSecret` grows
|
||
|
||
`src/DodoSSH.Client.Domain/HostGroupSecret.cs`, `HostGroupSecretCodec.cs`, `HostGroupSecretMerge.cs`.
|
||
|
||
- Add `ParentId`, `DefaultPort`, `DefaultUsername`, `DefaultSshKeyId`, `DefaultCredentialId`.
|
||
- `TryValidate`: reject `Guid.Empty` for each id, reject a `ParentId` equal to the group's own id where that is
|
||
knowable, apply the same 1–65535 range rule to `DefaultPort`, and refuse a group naming both a default key
|
||
and a default credential.
|
||
- **The codec needs the host codec's rule, which it does not have today.** `HostGroupSecretCodec` stamps
|
||
`CurrentSchemaVersion` unconditionally. Copy `HostSecretCodec.SchemaVersionFor` — a *maximum over the fields
|
||
actually present*, not a ladder — or upgrading one machine makes every group read-only on every other. A
|
||
group carrying none of the new fields must still encode at version 1, byte for byte.
|
||
- `HostGroupSecretMerge` gains the five fields, each a scalar.
|
||
- Add a group byte pin mirroring `AddingTheKeyField_DidNotChangeTheBytesOfAHostWithoutOne`. The group codec has
|
||
none, and the same "old vaults must re-encode identically" argument applies to it.
|
||
|
||
### 2. The `Tag` item kind
|
||
|
||
`SyncEntityType.Tag = 5`, `CryptoSpec.AadResourceType.Tag = 8`, `ChangeEntityType.Tag = 5` and the
|
||
`PublicAPI.Unshipped.txt` line **already exist** — no contract change, no crypto-spec change, no `docs/crypto.md`
|
||
change. `LocalCacheProtector`'s AAD switch already maps `Tag`.
|
||
|
||
New: `TagSecret.cs`, `TagSecretCodec.cs`, `TagSecretMerge.cs` in `DodoSSH.Client.Domain`; `TagCipher.cs`,
|
||
`TagRepository.cs` in `DodoSSH.Client.Sync`. Edited: `Client.Sync/ItemKinds.cs` (registry entry + `TagKind`),
|
||
`VaultSession.cs` (a `Tags` repository beside `HostGroups`), `Domain/Hosts.cs` (`VaultTag`),
|
||
`Infrastructure/DodoDbContext.cs`, `Infrastructure/Configurations/HostAndSyncConfigurations.cs`,
|
||
`Api/Features/Sync/ItemKinds.cs` (registry entry + server `TagKind`).
|
||
|
||
**A server migration is required** — a tag is its own table. Generate it, do not hand-write it:
|
||
`dotnet ef migrations add AddTagItem --project src/DodoSSH.Infrastructure`, committing all three resulting file
|
||
changes. **No client migration**: `ClientCacheContext` has one `item` table keyed by `(VaultId, EntityType,
|
||
EntityId)`, so a new kind is new rows.
|
||
|
||
Four traps, all of which pass a naive test suite:
|
||
|
||
- **`TagCipher` must say `AadResourceType.Tag` as a constant, never cast from `SyncEntityType.Tag`.** Tag is 5
|
||
on the wire and 8 in the crypto enum. A cast seals tags under `Credential`, which encrypts and decrypts
|
||
perfectly on the machine that wrote it and is a spec violation nothing notices until another implementation
|
||
refuses the item — and the AAD is frozen into stored ciphertext. `AadResourceTypeTests` is the test that
|
||
catches this, and it only catches it once `PinnedPairs` and `SealSample` have a Tag arm.
|
||
- **The `ItemKinds.Registry` entry is what `SyncEngine` pulls with.** `SyncedTypes` is projected from it. Miss
|
||
it and tags encrypt, merge and list perfectly on the machine that made them and are never once requested from
|
||
the server.
|
||
- **`TagKind.Fields` returns `null`, not an empty `SyncPlaintextFields`.** An empty record still serialises
|
||
`relayEnabled: false`, which invites a reader to believe the type has a relay setting that is off.
|
||
- **`ValidateFields` must refuse everything, with reasons.** There is no default; an unimplemented one accepts
|
||
whatever arrives. `RelatedId` matters more here than it did for a group — it is the field a future `HostTag`
|
||
would reach for, and `SyncPlaintextFields` is frozen so it cannot be removed. Follow `SnippetKind` and
|
||
`ObjectStoreKind`, which are more complete than `HostGroupKind`.
|
||
|
||
### 3. `HostSecret` grows, and `Port` goes nullable
|
||
|
||
`HostSecret.cs`, `HostSecretCodec.cs`, `HostSecretMerge.cs`, plus a new `TagSet` value type and a new resolver.
|
||
|
||
- `TagSet` is a structural-equality wrapper in the shape of `JumpChain` — a plain `IReadOnlyList<Guid>` on a
|
||
record gets reference equality from the compiler-generated `Equals`, which would make every host read as
|
||
changed on every sync pass and two identical edits register as a conflict. Unlike `JumpChain` it is a *set*:
|
||
order carries no meaning, so it sorts and dedupes, and it exposes a `ToIdMap()` for the merge.
|
||
- `HostSecretMerge` merges `TagIds` through `ThreeWayMerge.Map`, per tag, so two people each adding a different
|
||
tag to one host both keep theirs. It is not a scalar; a whole-value merge here would silently drop one side.
|
||
- `Port` becomes `int?`. `TryValidate`'s `is < 1 or > 65535` is already false for null, which is the wanted
|
||
behaviour but is silent — say so in a comment, and fix the message, which interpolates `{Port}` and renders
|
||
empty for null.
|
||
- **`SchemaVersionFor` needs branches for both new fields, and this is the one that loses data if forgotten.**
|
||
A host with `Port = null` written at version 1 omits the property (`WhenWritingNull`); an older client
|
||
deserialises `int Port` as 0, `TryValidate` refuses it, and the item reads as **unreadable rather than
|
||
read-only** — gone, not locked. Add `PortInheritSchemaVersion = 5` and `TagIdsSchemaVersion = 5` (or 5 and 6)
|
||
and make both bump the maximum.
|
||
- **`AddingTheKeyField_DidNotChangeTheBytesOfAHostWithoutOne` pins the exact bytes** of a minimal host,
|
||
including `"port":22`. A host that now inherits its port drops that key. Keep the pinned literal for a host
|
||
with an explicit port, and add a companion for the inheriting one — do not edit the old literal to match
|
||
whatever the code produces.
|
||
- `TagIds` must serialise **last** in `HostPayloadDocument`, and empty must serialise as absent, or every host
|
||
in every vault looks changed on the first sync after the upgrade.
|
||
|
||
New file: the resolver. Given a host and the group list, walk `GroupId` then `ParentId` with a visited set,
|
||
returning resolved port, username and binding, plus which group each came from — the editor needs the second
|
||
half for its placeholders. It must never return both a key and a credential.
|
||
|
||
### 4. The shared view model, and the two heads
|
||
|
||
`VaultViewModel` is where nearly all of it lands, and both heads get it at once because both bind the same
|
||
properties.
|
||
|
||
The choke points, from the connect-path trace:
|
||
|
||
- **`TryBuildAuthentication(HostSecret, …)` and `TryBuildConnectionRequest(HostSecret, …)`** both take a bare
|
||
`HostSecret` — this signature is where group context is currently lost. Both must take the resolved value.
|
||
This is the single highest-leverage change: it is the only auth resolution in the product, and both heads
|
||
and both transports go through it.
|
||
- The credential-username fallback becomes three levels: credential → host → group chain.
|
||
- `Complete(...)` must refuse on an empty username only *after* the chain has been consulted.
|
||
- `HostRowViewModel.Address`, `Dialled`, `TransfersViewModel`'s connected-to label and
|
||
`TerminalWorkspace.Describe` must show the **dialled** address. `MainWindowViewModel.Rank` searches
|
||
`Address`, so an unresolved one makes hosts unfindable by their real port.
|
||
- **`HostFields.From` in `HostCipher` must emit the resolved port.** This is the one place where an unresolved
|
||
read is a wrong wire rather than a wrong label: it fills the relay's plaintext columns, which is what the
|
||
*server* dials. A relay host with a null port also fails server validation outright.
|
||
- Host-key pinning keys on host and port. `ForgetHostKeyAsync` and the "pin in use" endpoint set read
|
||
`row.Host.Port` directly — a host inheriting 2222 pins under 2222 while both look under 22.
|
||
- `HostRowViewModel.Authentication`, `SelectedHostAsksForAPassword` (in **both** `VaultViewModel` and
|
||
`TransfersViewModel`) and `SelectedHostAuthenticationNote` all switch on the host's own two ids and must
|
||
switch on the resolved binding, with new wording for a binding that came from a group.
|
||
- **`HostsBoundTo`** counts hosts naming a key explicitly. A key deleted while only a *group* names it warns
|
||
nobody and then refuses every host under that group at connect time. It must walk groups too.
|
||
- The editor: load must distinguish "unset" from "explicitly this", `BuildHost` must preserve that in both
|
||
directions, and each field needs the resolved value as its placeholder.
|
||
- `ImportViewModel.IsAlreadyPresent` compares port and username directly, so a stored host inheriting 22 will
|
||
never match an imported host at 22 and the import screen re-offers duplicates. Decide whether an imported
|
||
block with no `Port` should inherit rather than pin 22 — `SshConfigResolver` returns `DefaultPort` today.
|
||
|
||
### 5. The phone
|
||
|
||
`Views/HostsScreen.axaml` and `Theme/Phone.axaml`. No csproj edit — Avalonia globs `**/*.axaml`. Compiled
|
||
bindings are on, so a binding to a property that does not exist is a build error; `TreatWarningsAsErrors` is on
|
||
repo-wide, so any XAML warning fails CI.
|
||
|
||
- A `Button.fab` style, and the comment that currently refuses one rewritten to say what it now opens.
|
||
- The `+` needs a `Panel` wrapping the screen's root `Grid` so it can sit bottom-right without moving. Placing
|
||
it inside the list row would put it above the connect bar, which appears and disappears with the selection.
|
||
- The bottom sheet follows `HostKeySheet.axaml`, the head's one existing sheet: a scrim
|
||
(`Border Background="#9E0E1220"`, a literal because the palette holds no alpha surface), a bottom-aligned
|
||
`Border` with `CornerRadius="22,22,0,0"`, a decorative grab handle, and **no tap-to-dismiss** unless it is
|
||
wired by hand, because nothing on this head implements it.
|
||
- **Scrim reach is a real choice.** Declared inside `HostsScreen`, a scrim darkens the screen area only and the
|
||
64px nav bar stays lit and tappable. To cover the display the sheet has to sit in `PhoneShell.axaml` beside
|
||
`HostKeySheet`, which is exactly why that control lives there.
|
||
- **The back gesture needs a new guard**, above the `switch` in `PhoneShell.axaml.cs`, in the shape of the
|
||
host-key guard: back should close the sheet or the editor rather than leave the screen. The comment on that
|
||
method states an invariant about the switch cases staying in step with the surface tests — so add a guard,
|
||
do not extend the switch. *(This named `IsVaultsSurface` and `IsConnectionsSurface`. Neither exists
|
||
anywhere in the repo; the real properties are `IsMoreSurface` and `IsTerminalSurface`, and only the first
|
||
is what the switch mirrors.)*
|
||
- The editors follow `SnippetsScreen.axaml`: a `Border Classes="card"` in the same grid row as the list,
|
||
toggled on `IsEditing`, with the list toggled on `!IsEditing`. There is no dialog, no modal and no
|
||
editor-screen anywhere on this head, and the reason is written down — a form stacked over the list hides what
|
||
it is about.
|
||
- Editing an existing host comes nearly free: the shared `IsEditing` panel serves both, so the connect bar gets
|
||
an EDIT button beside CONNECT. Not asked for, but a `+` that adds hosts with no way to correct one is a
|
||
strange thing to ship.
|
||
|
||
### 6. Tests
|
||
|
||
House style: `Subject_Predicate`, articles included, the predicate smuggling in the reason
|
||
(`_RefusesRatherThanFallingBackToThePassword`). No `Async` suffix on test methods; always on private helpers.
|
||
Every class carries a remark naming the class of failure it exists to catch. xunit.v3 + Shouldly, with the
|
||
because-string used as prose.
|
||
|
||
- Three shared builders need the new fields: `Domain.Tests/HostFactory.cs`, `Sync.Tests/SyncHarness.cs`,
|
||
`Sync.Tests/HostCipherTests.cs`. There is no shared group factory and with five new fields there should be.
|
||
- Three guard tests fail by design and that is what they are for:
|
||
`HostSecretMergeTests.EveryScalarField_IsRoutedThroughAMerge` (note `GroupId` is missing from its `with`
|
||
block today — an existing gap worth closing while there),
|
||
`ValueSemanticsTests.TryValidate_RejectsWhatCannotBeStored`, and the two "groups are flat" remarks.
|
||
- `ItemKindsTests.ThePullFilterNamesEveryTypeThisBuildSynchronises` is an ordered list — add Tag in registry
|
||
order. `AadResourceTypeTests` needs `PinnedPairs`, a `SealSample` arm and a `NewTag()` builder.
|
||
- `SyncEndpointTests.AHostGroupCarryingAParent_IsRejected` asserts the server refuses a plaintext `ParentId`
|
||
with a reason containing "flat". Putting the parent **inside the payload** does not break it mechanically,
|
||
but its stated reason becomes wrong. It should survive with a rewritten comment — the parent lives in the
|
||
payload, the plaintext column stays refused, and ADR 0004 is why. Decide that deliberately rather than
|
||
letting it drift.
|
||
- `Push_AnUnsupportedEntityType_IsInvalidNotAFailedBatch` picks the first type with no kind registered, very
|
||
likely Tag today. It self-heals to `HostTag` via `Assert.SkipWhen`.
|
||
- `App.Layout.Tests` measures pixels and bends rather than breaks. Extend the seeders — nesting and a tag row
|
||
change what the widest realistic content is — rather than the assertions. `ScreenLayoutTests.cs:1310` pins
|
||
`ChangedFields = "Hostname, Port, Username, Options, Group"` as a literal; add `Tags` to keep it measuring
|
||
the worst case.
|
||
- `ShellFlowTests.ReadyToConnectAsync` gives its host both a username and a port, so the inheritance tests need
|
||
a host with neither, or the group is never the source.
|
||
|
||
## Found on the way, and out of scope
|
||
|
||
`LocalCacheProtector`'s AAD switch is missing `ConnectionLogEntry`, `ActivityLogEntry` and `ObjectStore`, so
|
||
`ConflictStore.Record` throws `ArgumentOutOfRangeException` on a conflict for any of those three. Pre-existing,
|
||
unrelated to any of this, and `Tag` is already in that switch. Worth a separate fix.
|
||
|
||
## Prose that becomes false
|
||
|
||
Not a tidy-up — these are the places the codebase currently tells a user or a maintainer that this feature is
|
||
deliberately absent, and each states a reason that will no longer hold.
|
||
|
||
- `Theme/Phone.axaml` — the "No floating action button" block.
|
||
- `Views/HostsScreen.axaml` — the v2 and v3 notes on the missing `+`.
|
||
- ~~`Views/ConnectionsScreen.axaml`~~ — **this file does not exist and never did.** The real inventory is
|
||
the two above plus `README.md`, `docs/android-port.md` and `docs/design-import-gaps.md`. Neither phone
|
||
site was "rendered on screen": both are XAML comments.
|
||
- `HostGroupSecret.cs` and `HostGroupSecretTests.cs` — "No parent. Groups are flat."
|
||
- `docs/design-import-gaps.md` — the **Add host** row, the two floating-button rows, the "Tag / HostTag still
|
||
reserved and unused" paragraph, and the tag-chips and groups-on-a-team's-hosts rows in the Hosts table.
