Implements the runtime side of `molecule connect <id>`. After this PR
the CLI can actually attach to an external workspace and round-trip
inter-agent messages through any registered backend.
What's in:
- `internal/connect/client.go` — platform-API client with bearer auth.
Endpoints: POST /registry/register (delivery_mode=poll, no URL),
POST /registry/heartbeat, GET /workspaces/:id/activity?type=a2a_receive,
POST /workspaces/:id/a2a (reply target).
Errors split into TransientError (network/5xx — retry with backoff)
and PermanentError (4xx — abort with clear message).
- `internal/connect/state.go` — atomic cursor persistence at
~/.config/molecule/state/<workspace-id>.json. Mode 0o600 (owner-only)
from day 1 because future state additions may include rotated tokens.
Atomic write-then-rename so a crash mid-write can never produce a
half-written cursor.
- `internal/connect/connect.go` — Run() orchestrator. Wires register-
with-bounded-retry, then heartbeat goroutine + poll goroutine.
Both respect ctx cancellation for clean SIGTERM.
Robustness contract per RFC #10:
* Cursor advances AFTER successful dispatch — crash mid-batch
re-delivers, never drops.
* 410 on cursor lookup → reset to "" and re-fetch (don't deadlock
on a pruned cursor).
* Heartbeat permanent error stops the heartbeat loop only; poll
loop keeps running so the operator sees "stopped" + reason in
logs and can SIGTERM.
* Backend dispatch is sequential within a batch (avoids out-of-
order replies for in-flight conversations).
* Inter-agent reply path: POST envelope to /workspaces/<source>/a2a.
* Canvas-origin reply (source_id == nil) logs + skips for now —
M1.3 wires that via the task_update activity convention.
- `internal/cmd/connect.go` — runConnect now actually calls
connect.Run() (was a placeholder ctx-wait in M1.1).
Test plan:
- httptest workspace-server stub covers register / heartbeat / activity
/ a2a reply endpoints.
- TestRun_RoundTrip_AgentReply: end-to-end ping → mock backend → pong
reply lands at source, cursor saved.
- TestRun_CanvasOriginMessageNotReplied: source_id=nil → backend fires
but no reply post; cursor still advances.
- TestRun_CursorPruned410ResetsAndContinues: server returns 410 once,
cursor resets to "", next poll dispatches the fresh row.
- TestRun_PermanentRegisterErrorAborts: 401 surfaces immediately.
- TestRun_TransientRegisterErrorRetries: 503 then 200 → register
succeeds on second attempt.
- TestRun_OptionsValidation: missing Backend / WorkspaceID surface
before any I/O.
- State: round-trip, file mode 0o600, atomic-rename leaves no .tmp
artifacts, corrupted file surfaces error.
- All tests green under -race.
Out of scope (next PRs in this stack):
- M1.3: claude-code backend (canvas-origin reply convention rides
with this)
- M1.4: GoReleaser tag-triggered release.yml workflow
- Push-mode (--mode push currently surfaces a clear "M4" error)

First step toward `molecule connect <id>` — the out-of-box external-
runtime workspace connector specified in RFC #10.
What's in this PR (foundational, ~300 LOC of code + matching tests):
- `internal/backends.Backend` — the seam every concrete handler
implements: HandleA2A(ctx, Request) → Response, Close(). Two methods,
no inheritance, no surprise side effects. Concurrency-safe by
contract (poll dispatch may parallelise).
- Request/Response/Part/Config types — lossless JSON-RPC mirror so
backends can re-issue downstream without re-parsing.
- Compile-time registry — `Register("name", factory)` from each
backend's init(); `Build(name, cfg)` selects at runtime. Panics
on duplicate registration so drift fails loudly at startup, not
on first message.
- `mock` backend — single-template echo for CI smoke + tests + demos.
`--backend-opt reply="<template>"` with `%s` for inbound text.
- `molecule connect <workspace-id>` cobra command — flag surface,
validation, --dry-run for smoke. Loops (heartbeat, activity poll,
dispatch) land in M1.2 in internal/connect/.
Coverage:
- Registry: duplicate-name panic, empty-name panic, nil-factory panic,
Build unknown-name error includes registered list.
- Mock: default template, custom template, text-part concatenation,
Final=true on terminal response.
- Connect: --backend-opt KEY=VALUE parser (incl. value with =),
flag validation (missing token, bad mode, bad opt, unknown
backend), --dry-run happy path.
All tests pass under -race.
Out of scope (subsequent M1 PRs):
- M1.2: heartbeat + activity poll loops in internal/connect/
- M1.3: claude-code backend (wraps molecule-mcp-claude-channel)
- M1.4: GoReleaser tag-triggered release.yml workflow

The yaml-output-support refactor removed the combined json/yaml if-block
but left a dangling `}` that closed runPlatformHealth prematurely,
putting the tabwriter block outside the function body.
Removes the stray brace at line 137. CI vet was failing with:
platform.go:138:2: syntax error: non-declaration statement outside function body

The `--output yaml` flag was accepted but aliased to JSON since
printYAML() was never defined. Add printYAML() using gopkg.in/yaml.v3
(already an indirect dep via viper) and split all output format
branches into explicit json/yaml/table paths.
Affected commands: workspace list/create/inspect/audit,
agent list/inspect/peers, platform audit/health.

- Change rootCmd Use/Short/Long from 'mol' to 'molecule'
- Register initCmd in root so 'molecule init' works
- Update viper config name lookup from 'mol' to 'molecule'
- Fix config init/set to write molecule.yaml instead of mol.yaml
- Update all user-facing strings mol→molecule
Fixes TestCLI_Version, TestCLI_Init, TestCLI_ConfigInit, TestCLI_Completion_GeneratesScript
Go 1.25 resolves "./cmd/molecule" relative to cmd.Dir as an absolute path
under the CWD, producing the doubled "cmd/molecule/cmd/molecule" error.
Building the whole module from the root and relying on the binary name
from -o is the idiomatic Go approach and avoids path arithmetic entirely.
Also tightened error message to match the new command.

os.Executable() in Go 1.x parallel tests resolves to <TempDir>/0/molecule.test
making path-based traversal from the binary back to the repo root unreliable.
Switch to os.Getwd() which always returns the repo checkout root in CI
(where `go test ./cmd/molecule/...` is invoked), and skip any path arithmetic.

v.SafeWriteConfig() was called without a local viper instance.
Create a fresh viper scoped to the target config file, read any
existing values, set the new key, then atomically write via SafeWriteConfig.

viper.Viper has no Marshal method in v1.21. Use SafeWriteConfig instead
which atomically writes only explicitly-set keys to the config file.

Wires shell completion for all 4 shells via Cobra's built-in generators.
Covers the remaining item from the implementation status checklist.
Adds:
- internal/cmd/completion.go: cobra.GenXxxCompletion wrappers with
usage examples for each shell
- 5 new integration tests in cmd/molecule/molecule_test.go:
- TestCLI_Completion_Help (4 shells × help flag)
- TestCLI_Completion_GeneratesScript (4 shells × script output)
- TestCLI_Completion_InvalidShell (exit code 2 on bad shell)

All test.Fatalf messages referenced "mol <subcommand>" but the binary
is now "molecule". Also fix configSet to use os.WriteFile atomic write

Rename all user-facing "mol" references to "molecule" to match the
published binary name (binary: molecule in .goreleaser.yaml):
- root.go: Use string, versionInfo, viper config name, flag descriptions
- init.go: section comment, Short, Long, cfgPath, scaffolded message
- config.go: Long description, Shorts, configFile, WriteFile, Stat check
- molecule_test.go: binary name, version output check, mol.yaml → molecule.yaml
Also fix test helper to use runtime.GOEXE instead of hardcoded /tmp/go/bin/go.

rootCmd.Use was "mol" while .goreleaser.yaml sets binary: "molecule".

- Add `mol init` command (internal/cmd/init.go): scaffolds mol.yaml
in the current directory with commented config sections and
environment variable documentation. Exits with a clear "next steps"
message. Checks for existing mol.yaml before overwriting.
- Register initCmd in root.go alongside the other command groups.
- Add 2 integration tests: TestCLI_Init (scaffolding + output)
and TestCLI_Init_AlreadyExists (error path).
- Update CLAUDE.md command reference to list mol init and note it
is checked off the stub repo checklist.

package path (./cmd/molecule not ./cmd/molecli)
- Add test job (go mod tidy + vet + test) to release.yml, runs on
every PR touching Go files
- Release job gated on test job; conditional on v* tag push
- Mark KI-005 resolved in known-issues.md
