* fix(daemon/execenv): refresh stale Codex config copies across env reuse (MUL-2646)
`copyFileIfExists` previously short-circuited whenever the per-task
`codex-home/{config.toml,config.json,instructions.md}` already existed,
so once the files were seeded at first Prepare they were never refreshed
again — even though `Reuse()` calls `prepareCodexHomeWithOpts` on every
resume. A user who rotated their Codex `~/.codex/config.toml` between
runs (e.g. switching the active `[model_providers.X]` `base_url`, or
pointing `env_key` at a freshly rotated API key) kept reading the stale
per-task copy on session resume. Codex then issued requests to the new
URL using the old key and the API rejected the token.
Treat any existing `dst` as something to drop and re-copy from the
current shared source, mirroring the symlink path that already refreshes
`auth.json` (#2126). The daemon-managed sandbox / multi-agent / memory
blocks are applied via marker-bracketed idempotent passes after the
copy, so a re-copy + re-ensure cycle preserves them.

* fix(daemon/execenv): drop per-task Codex copy when shared source removed (MUL-2646)
Extend the MUL-2646 fix to the deletion arm of "sync the shared source":
`syncCopiedFile` (renamed from `copyFileIfExists`) now also removes the
per-task `dst` when the shared `src` is absent. The prior version
short-circuited on missing src and left `config.toml` / `config.json` /
`instructions.md` from the previous Prepare lingering in the per-task
home — so a user who removed a provider by deleting `~/.codex/config.toml`,
or pulled `config.json` / `instructions.md` out of the shared home, would
keep replaying the stale copy on session resume.
For `config.toml` the subsequent `ensureCodex{Sandbox,MultiAgent,Memory}Config`
passes recreate the file with only the daemon-managed default blocks, so
removing the shared file cleanly drops every user-managed
`[model_providers.X]` / `model_provider` line. For `config.json` and
`instructions.md` there is no daemon default, so they disappear in
lockstep with the shared source.
Adds `TestPrepareCodexHome_DropsCopiedConfigWhenSharedSourceRemoved`
covering the new path, and extends the refresh-arm test to assert the
multi-agent / memory marker blocks are still present after the copy is
refreshed.

Codex CLI's auto-memory subsystem writes summaries to
`$CODEX_HOME/memories/raw_memories.md` and `state_*.sqlite`, then reads
them back on the next turn. The daemon never cleared these files across
Reuse(), and Codex CLI may also pull from user-level `~/.codex/memories/`
entirely outside the per-task isolation. Either path leaks unrelated
context into new Multica tasks — multica#3130 saw `D:\Project\MoHaYu\
WowChat` Raw Memories injected into a brand-new issue's first turn.
Write a daemon-managed block into the per-task `config.toml` that sets
`features.memories = false`, `memories.generate_memories = false`, and
`memories.use_memories = false`. Codex then neither writes nor reads
its memory subsystem regardless of where the residual files live. The
user's global `~/.codex/config.toml` is never touched.
Pattern mirrors `ensureCodexMultiAgentConfig`: idempotent managed-block
upsert, two TOML layout variants (root dotted-key vs. inside a `[features]`
/ `[memories]` table) to satisfy strict toml-rs parsing, and a
`MULTICA_CODEX_MEMORY` env-var escape hatch.

`ensureSymlink` previously short-circuited whenever `dst` already existed
as a regular file ("Regular file exists — don't overwrite"). On Windows
that branch is reachable via the createFileLink copy fallback that fires
when `os.Symlink` is unavailable, so once a per-task `codex-home/auth.json`
was written as a copy it would never be refreshed by subsequent
Prepare/Reuse calls. If the shared `~/.codex/auth.json` rotated (e.g.
Codex Desktop refreshed the token in the background), the daemon kept
handing Codex a now-revoked refresh_token, which the OAuth server
rejected with `refresh_token_reused` / `token_expired`. Renaming the
workspace directory was the only recovery path.
Treat any non-matching dst — wrong-target symlink, broken symlink, or
stale regular file — as something to delete and re-create via
createFileLink, so each Prepare/Reuse mirrors the current shared source.
Add a `logCodexAuthState` info log (file kind, link target, size, mtime —
never contents) so operators chasing the same symptom can see at a glance
whether the per-task home is tracking the shared auth or has drifted.
Tests cover: stale regular-file dst is replaced, copy-fallback dst is
refreshed when the shared source rotates, and a high-level
prepareCodexHome regression simulating the Windows + token-rotation
scenario from issue #2081.

* fix(execenv): default-disable Codex native multi-agent in per-task config
Recent Codex app-server releases enable features.multi_agent by default,
exposing spawn_agent / wait / close_agent tools that let a parent thread
spawn nested subagents. The daemon currently models only the parent thread,
so the parent's turn/completed is treated as task completion even when
spawned children are still running — leading to premature task completion
and dropped child output.
Disable features.multi_agent by default in the per-task CODEX_HOME/config.toml
so Multica's task lifecycle is the only orchestration layer in play. Strip
both the dotted-key form (features.multi_agent) at TOML root and the
multi_agent key inside a [features] table; siblings and unrelated tables
are preserved. Honor MULTICA_CODEX_MULTI_AGENT=1 as an opt-out for users
who explicitly want Codex native subagents inside a Multica task.
The user's global ~/.codex/config.toml is never modified — only the daemon's
isolated per-task copy.
Also widen managedBlockRe to consume `\n*` rather than `\n?` so reruns
don't accumulate blank lines when both the sandbox and multi-agent managed
blocks coexist.
* fix(execenv): inject managed multi_agent inside existing [features] table
Per PR review (codex_multi_agent.go:77-83 vs :112-115): when the user's
config.toml already has a top-level `[features]` table, writing
`features.multi_agent = false` at the TOML root implicitly redefines the
same `features` table. The strict TOML parser used by Codex (`toml-rs`)
rejects that with `table 'features' already exists`, so Codex would fail
to load the per-task config and refuse to start the thread. Verified the
strict-parser failure with pelletier/go-toml/v2; the previous
BurntSushi/toml-based regression test was permissive enough to miss it.
Detect a root-level `[features]` header and place the managed block
inside that table (`multi_agent = false` with marker comments). When no
such header exists, keep the existing root-level dotted-key form. The
managed-block regex matches both layouts so reruns and layout
transitions stay idempotent. A `[features.experimental]` sub-table
without a bare `[features]` header still uses the root dotted-key form,
which is spec-valid (no explicit redefinition).
Tests now use pelletier/go-toml/v2 to actually parse the output and
assert features.multi_agent decodes to false; the regression case from
the PR review is covered explicitly.

Codex Desktop writes one [[skills.config]] entry per known skill into
~/.codex/config.toml. File-backed entries get path = "...", but
plugin-backed entries (e.g. name = "superpowers:brainstorming") only get
a name. Codex CLI 0.114's TOML deserializer treats path as required, so
it rejects the plugin entries with "missing field path" and fails
thread/start.
The daemon copies ~/.codex/config.toml verbatim into each task's
isolated codex-home, which propagated those broken entries into the
per-task config and blocked every Codex agent run for affected users.
Strip the whole [[skills.config]] array on copy. Multica writes the
agent's currently assigned skills directly to codex-home/skills/ and
Codex auto-discovers them from there, so the user-level skill registry
is redundant for a per-task run.
Closes#1753
Merge the two symlink removal branches in exposeSharedCodexPluginCache —
they shared the same os.Remove + recreate path with only the error label
differing. The branch is now keyed off Lstat's ModeSymlink bit, with
Readlink reused only to fast-path an already-correct link. Behaviour is
unchanged; just less duplicated code.
Expose the shared Codex plugin cache inside each per-task CODEX_HOME before launch so plugin-provided skills are available on the first session.
Refresh agent-assigned workspace skills for both newly prepared and reused Codex environments, and cover plugin cache plus reuse behavior with focused execenv tests.
* fix(daemon): platform-aware Codex sandbox config to unbreak macOS network
On macOS, Codex's Seatbelt sandbox in workspace-write mode silently
ignores '[sandbox_workspace_write] network_access = true' (see
openai/codex#10390). That blocks DNS inside the sandbox, so 'multica
issue get' and other CLI calls fail with 'dial tcp: lookup ...: no such
host' — this is what caused MUL-963.
Changes:
- New server/internal/daemon/execenv/codex_sandbox.go: picks a sandbox
policy based on runtime.GOOS and the detected Codex CLI version.
Non-darwin or darwin with a known-fixed version keeps workspace-write
+ network_access=true; older darwin falls back to danger-full-access
and logs a warn with upgrade hint. The fix-version threshold is a
single constant (CodexDarwinNetworkAccessFixedVersion) so it's easy
to bump once upstream ships.
- Per-task config.toml now gets a 'multica-managed' marker block
(BEGIN/END comments) rewritten idempotently; user-owned keys outside
the markers are preserved. Legacy inline sandbox directives from
earlier daemon versions are stripped on migration.
- execenv.PrepareParams gains CodexVersion; execenv.Reuse takes a
codexVersion arg; daemon.go caches detected versions at registration
and threads them through to Prepare/Reuse.
- Replaces the old ensureCodexNetworkAccess tests with
platform-parameterised coverage (linux vs darwin, idempotency,
legacy-migration, policy matrix).
- docs/codex-sandbox-troubleshooting.md: symptom fingerprint table,
decision matrix, self-check commands, trade-offs.

* fix(daemon): hoist managed sandbox block above user tables (MUL-963)
Review on #1246 flagged that upsertMulticaManagedBlock appended the
managed block to EOF. If the user's config.toml ends inside a TOML table
(e.g. [permissions.multica] or [profiles.foo]), a trailing bare
sandbox_mode = "..." is parsed as a key of that preceding table, so
Codex silently ignores the policy the daemon meant to apply.
Two changes make the block position-independent:
- renderMulticaManagedBlock now emits only top-level key=value lines and
uses TOML dotted-key form (sandbox_workspace_write.network_access =
true) instead of opening a [sandbox_workspace_write] header. The block
therefore neither inherits from nor leaks into any surrounding table.
- upsertMulticaManagedBlock always hoists the block to the top of the
file (stripping any previously written managed block first), so the
sandbox_mode line is always at the TOML root regardless of what the
user put below it. This also migrates configs written by the original
PR #1246 logic where the block was trapped behind a user table.
Added tests for the regression scenario (pre-existing [permissions.*]
table) and the legacy-trailing-block migration; updated the existing
Linux default test and the troubleshooting runbook to reflect the
dotted-key form.

On Windows, os.Symlink requires Developer Mode or admin privileges.
Extract symlink creation into platform-specific files: on non-Windows,
behavior is unchanged (os.Symlink). On Windows, try os.Symlink first,
then fall back to directory junctions (mklink /J) for dirs and file
copy for files.

Codex tasks running in workspace-write sandbox mode could not resolve
api.multica.ai because the hardcoded sandbox parameter in thread/start
overrode any config.toml settings, and the default sandbox policy blocks
network access.
Changes:
- Remove hardcoded `sandbox: "workspace-write"` from thread/start RPC —
let Codex read sandbox config from its own config.toml instead
- Auto-generate config.toml in per-task CODEX_HOME with
`sandbox_mode = "workspace-write"` and `network_access = true`,
preserving any existing user settings
- Fix Reuse() to restore CodexHome for Codex provider on workdir reuse
Closes#368
Per-task CODEX_HOME isolated session logs in per-task directories, making
them invisible from the global ~/.codex/sessions/ where users expect to
find them. Symlink the sessions directory back to the shared home so
Codex writes session logs to the global location while keeping skills
isolated per task.

Write skills to provider-native paths so agents discover them
automatically instead of relying on manual path references in
CLAUDE.md/AGENTS.md.
- Claude: write to {workDir}/.claude/skills/ (native discovery)
- Codex: write to per-task CODEX_HOME/skills/ with auth/config
seeded from ~/.codex/ (symlink auth.json, copy config files)
- Fallback: keep .agent_context/skills/ for unknown providers
