* fix(core/test): split connection.test.ts from DB-test batch to avoid mock pollution (coleam00#1269)

messages.test.ts uses mock.module('./connection', ...) at module-load time.
Per CLAUDE.md:131 (Bun issue oven-sh/bun#7823), mock.module() is process-
global and irreversible. When Bun pre-loads all test files in a batch, the
mock shadows the real connection module before connection.test.ts runs,
causing getDatabaseType() to always return the mocked value regardless of
DATABASE_URL.

Move connection.test.ts into its own `bun test` invocation immediately
after postgres.test.ts (which runs alone) and before the big DB/utils/
config/state batch that contains messages.test.ts. This follows the same
isolation pattern already used for command-handler, clone, postgres, and
path-validation tests.

* fix(setup): align PORT default on 3090 across .env.example, wizard, and JSDoc (coleam00#1152) (coleam00#1271)

The server's getPort() fallback changed from 3000 to 3090 in the Hono
migration (coleam00#318), but .env.example, the setup wizard's generated .env,
and the JSDoc describing the fallback were not updated — leaving three
different sources of truth for "the default PORT."

When the wizard writes PORT=3000 to ~/.archon/.env (which the Hono
server loads with override: true, while Vite only reads repo-local
.env), the two processes can land on different ports silently. That
mismatch is the real mechanism behind the failure described in coleam00#1152.

- .env.example: comment out PORT, document 3090 as the default
- packages/cli/src/commands/setup.ts: wizard no longer writes PORT=3000
  into the generated .env; fix the "Additional Options" note
- packages/cli/src/commands/setup.test.ts: assert no bare PORT= line and
  the commented default is present
- packages/core/src/utils/port-allocation.ts: fix stale JSDoc "default
  3000" -> "default 3090"
- deploy/.env.example: keep Docker default at 3000 (compose/Caddy target
  that) but annotate it so users don't copy it for local dev

Single source of truth for the local-dev default is now basePort in
port-allocation.ts.

* fix(providers/claude): use || instead of ?? in hasExplicitTokens to handle empty-string env vars (coleam00#1028)

Closes coleam00#1027

* chore(deps): bump claude-agent-sdk to 0.2.121, codex-sdk to 0.125.0 (coleam00#1460)

Both SDKs were ~30 patch releases behind. Validation suite passes
(type-check, lint, format, tests across all 10 packages) without code
changes. The only sustained Claude SDK behavior change in the range —
v0.2.111's options.env overlay/replace flap, since reverted to overlay —
is a no-op for Archon, which already passes { ...process.env } as the
SDK env.

* fix(cli): lazy-import bundled skill files so non-setup commands don't crash on missing source (coleam00#1394)

The 18 top-level `import … with { type: 'text' }` statements in
`bundled-skill.ts` resolve at module load. For `bun build --compile` that's
build time, so the binary embeds the strings and works regardless of any
on-disk skill files. For `bun link` (linked-source) installs that's every
`archon` invocation — including `archon --help`, which doesn't even use the
skill content. If any of the 18 source files are missing or moved, the
import fails and the CLI cannot start at all.

The skill content is data the binary deploys via `archon setup`, not data
the CLI needs at runtime. There's only one consumer in production code:
`copyArchonSkill()` in `setup.ts`. Moving the import into that function as
a dynamic import preserves the compiled-binary behavior (Bun's bundler
statically analyses literal-string `import()` and embeds the chunk —
verified by grepping the SKILL.md frontmatter out of a freshly compiled
binary) while making the linked-source install resilient: only `archon
setup` triggers the bundled-skill module load now. Verified: a known skill
string appears in the compiled binary 1×, and `archon --help` no longer
needs the source files to start.

`copyArchonSkill()` becomes async because the dynamic import is a Promise.
The single production call site is already in an async function and gets
an `await`. The four `setup.test.ts` cases become async too.

* fix(claude): stop passing --no-env-file to native binary in dev mode (coleam00#1461)

* fix(claude): stop passing --no-env-file to native binary in dev mode

The Claude Agent SDK switched from shipping `cli.js` inside the package
to per-platform native binaries via optional deps somewhere in the
0.2.x series. As of 0.2.121 there is no `cli.js` in the SDK package;
dev mode resolves to `@anthropic-ai/claude-agent-sdk-darwin-arm64/claude`
(Mach-O). That native binary rejects `--no-env-file` with
`error: unknown option '--no-env-file'` and the subprocess exits 1.

`shouldPassNoEnvFile` was returning true on `cliPath === undefined` on
the assumption that "dev mode = JS executable run via Bun". That
assumption is dead. Tighten the predicate to only return true on an
explicit `.js` suffix, so we only emit the flag when the SDK is going
to spawn a Bun-runnable script.

CWD `.env` leak protection is unaffected. `stripCwdEnv()` in
`@archon/paths` (coleam00#1067) deletes Bun-auto-loaded `.env`/`.env.local`/
`.env.development`/`.env.production` keys from `process.env` at every
Archon entry point before any subprocess is spawned. The native Claude
binary does not auto-load `.env` from its cwd either. `--no-env-file`
was belt-and-suspenders for the JS-via-Bun case only.

Verified end-to-end with a sentinel: added a unique
`ARCHON_LEAK_SENTINEL_$$` to Archon's `.env`, ran e2e-claude-smoke
with a bash probe checking the subprocess env. stderr shows
`[archon] stripped 23 keys from /Users/rasmus/Projects/cole/Archon
(.env, .env.local)` — sentinel was deleted. Bash node prints
`PASS: simple='4', no sentinel leak`. Workflow completes cleanly,
no `--no-env-file` rejection from the SDK binary.

bun run validate: green across all 10 packages.

* fix(claude): address review on coleam00#1461 (stale docs + test gaps)

Critical: file-level JSDoc at provider.ts:18 still claimed dev mode
resolves cli.js. Updated to reflect SDK 0.2.x's switch to per-platform
native binaries.

Important: security.md still listed --no-env-file as item 2 of
target-repo .env isolation. Scoped that bullet to legacy
Bun-runnable JS entry points and called out that native binaries
don't auto-load .env from cwd. Added an Unreleased Fixed entry to
CHANGELOG.md. Updated binary-resolver.ts JSDoc title that referenced
cli.js.

Polish: widened the predicate to accept .mjs and .cjs (also
Bun-runnable JS — matches the SDK's own internal extension list).
Dropped the redundant `passesNoEnvFile` log field that mirrored
`isJsExecutable`. Added unit cases for .mjs/.cjs (now true) and
.ts/.tsx/.jsx (deliberately false — never SDK entry points).

Added an integration test that mocks resolveClaudeBinaryPath to
return a .js path and asserts executableArgs: ['--no-env-file']
flows through buildBaseClaudeOptions all the way to the SDK call —
catches future regressions in the conditional spread.

bun run validate: green across all 10 packages.

* fix(orchestrator): clear stale session ID on error_during_execution to prevent infinite failure loop (coleam00#1294)

* fix(orchestrator): clear stale session ID on error_during_execution to prevent infinite failure loop

When a Claude API session expires (e.g. after container restart), the orchestrator
persists the new (failed) session ID from the error result, causing every subsequent
message in that conversation to hit the same error — an infinite failure loop.

Fix: on error_during_execution result, set assistant_session_id to NULL instead of
persisting the failed session ID. The next message starts a fresh session with full
context rebuilt from the DB. Conversation history is unaffected since it lives in
remote_agent_messages, independent of the Claude session.

Changes:
- updateSession() and tryPersistSessionId() now accept string | null
- Both handleStreamMode and handleBatchMode clear session ID on error_during_execution

Fixes coleam00#1280

* test(orchestrator): add stale session clearing tests + address review feedback

* fix(claude): honor CLAUDE_BIN_PATH in dev mode for libc-mismatch hosts (coleam00#1481)

* fix(claude): honor CLAUDE_BIN_PATH in dev mode for libc-mismatch hosts

The Claude Agent SDK auto-resolves its bundled native binary in
[linux-x64-musl, linux-x64] order. On glibc Linux hosts (Ubuntu/Debian/
Fedora), Bun installs both via optionalDependencies and the musl variant
is picked first; its ELF interpreter (/lib/ld-musl-x86_64.so.1) does not
exist on glibc, so spawn fails and the SDK reports a misleading "binary
not found" — the file is on disk, the loader is not.

The documented escape hatch CLAUDE_BIN_PATH was dead code in dev mode:
the resolver early-returned undefined when BUNDLED_IS_BINARY=false before
ever reading the env var. The only workaround was patching node_modules.

Move the env-var block above the BUNDLED_IS_BINARY return. Config-file
path stays binary-mode-only — it's per-repo, not per-machine; env is the
right knob for libc mismatches.

Behavior preserved:
- env unset                  → unchanged (undefined in dev, autodetect/throw in binary)
- env set + file exists      → resolved (was binary-only; now also dev)
- env set + file missing     → clear error (was binary-only; now also dev)

Closes coleam00#1474

* chore(claude): address CodeRabbit review on coleam00#1481

- CHANGELOG entry under [Unreleased] / Fixed describing the dev-mode
  CLAUDE_BIN_PATH escape hatch (previously ignored). Notes that
  config-file path remains binary-mode-only and that env-loading +
  target-repo .env isolation are unchanged downstream.
- Empty-string test pinning that CLAUDE_BIN_PATH='' falls through
  to undefined rather than throwing — protects against a future
  predicate typo that would treat empty as "set".
- One-line note in ai-assistants.md "Binary path configuration"
  section pointing dev-mode users at the env-var override for the
  glibc/musl mismatch case.

Skipped from the review:
- The other two docs-page rewrites (configuration.md /
  troubleshooting.md): the error message itself names CLAUDE_BIN_PATH,
  and coleam00#1474 documents the use case publicly. One mention in
  ai-assistants.md is enough for discovery.
- Type-style consistency tweaks in the test file: pure bikeshed.

* fix(deps): bump hono to ^4.12.16 and @hono/node-server to ^1.19.13 (closes coleam00#1484) (coleam00#1499)

* fix(orchestrator): create ~/.archon/workspaces before AI provider spawn (coleam00#1529)

* fix(orchestrator): create ~/.archon/workspaces before AI provider spawn

On a fresh install, ~/.archon/workspaces doesn't exist yet. The
orchestrator passes that path as cwd to the AI provider, which calls
spawn() — which raises ENOENT. The error is then misclassified as
"binary not found" in the friendly-error path, surfacing as an
incorrect "Claude binary not found" message.

Add ensureArchonWorkspacesPath() in @archon/paths that mkdir -p's the
directory and returns the path. Use it at the orchestrator's spawn-cwd
site so the directory is guaranteed to exist before spawn().

Other call sites of getArchonWorkspacesPath() (workflow discovery,
path-prefix comparisons) only consume the path string and don't need
the directory to exist; they keep using the pure getter.

Closes coleam00#1528

* test(orchestrator): assert ensureArchonWorkspacesPath is called

Capture the @archon/paths mock as a named variable and assert it was
called in the syncWorkspace handleMessage path. Without this, the test
suite passes even if orchestrator-agent.ts:824 reverts to the
non-ensuring getArchonWorkspacesPath() variant — exactly the regression
that surfaced as 'Claude Code native binary not found' in coleam00#1528.

* docs(changelog): add Tier 1 batch 2 cherry-pick entry
