Dai Ha 97e4c1d658 fleetd #474: ConfigRef.reload() runs the charter tool-surface gate too
CI / build (pull_request) Successful in 1m25s
CI / contract (pull_request) Successful in 1m39s
A charter naming an MCP tool the server does not register refused Fleetd.main
at startup but slipped through ConfigRef.reload(), because reload() only ran
FleetConfig.validateAll(), which never looks at what a charter's text names.

CharterToolSurface stays in the mcp package (config must not depend on it), so
ConfigRef now accepts the check as a Consumer<FleetConfig> extraValidation,
run inside reload()'s same try/catch as validateAll(). Fleetd.main wires a new
package-private adapter, Fleetd.assertChartersNameOnlyRegisteredTools, into
both the startup call site and ConfigRef's constructor, so the two call sites
can never check different things.

Tests: ConfigRefTest (reload refuses/accepts, via a locally-built equivalent
consumer since Fleetd's method is package-private to dev.ltms.fleet) and the
new FleetdConfigRefCharterToolSurfaceWiringTest (same proof through the exact
Fleetd::assertChartersNameOnlyRegisteredTools reference production uses).
Verified deleting the new extraValidation.accept(fresh) call site fails both
new "refuses" tests by name.

Dai Ha 435e022560 Merge #471: seeded skills reach an opencode member, and instructions[] stops depending on write order (fleetd #393)
memberSkills: copied skill folders into every provisioned worktree's
.claude/skills/ and stopped there. Claude Code reads that directory
natively; opencode never does. So the feature was INERT for opencode
members rather than broken: the copy succeeded, the files were correct,
and nothing ever read them. No test failed because there was nothing to
fail - the feature worked at the only layer it implemented.

An opencode member's only channel for static guidance is the instructions[]
array in its generated config. OpenCodeLauncher now adds each seeded
skill's SKILL.md there. A folder with no SKILL.md is never delivered and
the log names it.

The second half is an ordering hazard fleet01 found by reading, and that I
then measured. Three writers append to instructions[]: the role charter,
the seeded skills, and the IDE rules. The charter used putArray
(CREATE-OR-REPLACE) while the other two used withArray (get-or-create).
That was safe only because the charter ran first against an empty array -
an undeclared constraint that nothing tested. Measured on the earlier
merge: making the skills writer use putArray left 1603 tests green while
silently deleting the charter entry, so an opencode member would launch
with no role contract at all. Worse than the bug being fixed, and
invisible.

All three writers now use withArray, and three tests pin the array's
CONTENTS (never its size - a size assertion passes when putArray swaps two
entries for two others) across the combinations that matter:
charter-only, charter+ide, charter+skills+ide.

Credit where it is due: fleet01 supplied the mechanism by reading the code
and I supplied the consequence by mutating it. Their later point is the one
worth keeping - the reason nothing caught that mutation is narrower than
"the ordering was undeclared". NOTHING ASSERTED THE CHARTER REACHES AN
OPENCODE MEMBER AT ALL. That assertion should have existed since the
charter feature shipped. #393's worker inherited that hole rather than
creating it, and the mutation only exposed it. It is now
instructionsArrayHoldsExactlyTheCharterWhenNothingElseWritesToIt.

One honest residue: the charter writer's own idiom cannot be pinned.
Flipping it back to putArray leaves the suite green, and always will,
because it runs first against an empty array where the two idioms are
equivalent. The edit removes an undeclared constraint for the next person
to add a writer; it is not a change any test can detect. The comment in
the source said two named tests cover it - that was wrong, and I corrected
it rather than leaving a false claim beside the code.

What this does NOT do: opencode has no equivalent of Claude Code's Skill
tool, so the content is static system-prompt text present from spawn, not
something a member can invoke by name. This closes the DELIVERY gap and
cannot close the ACTIVATION gap. That residue is opencode's design.

Numbers and my own mutation battery are on the ticket, measured on this
merge commit.

Dai Ha 9e4e423ad6 fleetd #393 follow-up: remove the instructions[] writer-ordering hazard
CI / contract (pull_request) Successful in 1m22s
CI / build (pull_request) Successful in 2m11s
OpenCodeLauncher.writeConfig has three writers into the instructions[]
array (charter, seeded skills, IDE rules). The charter writer used
putArray (create-or-REPLACE) instead of withArray (get-or-create), which
"worked" only because it happened to run first against a still-empty
array — an undeclared ordering dependency nothing tested. Found by the
fleet01 lead and verified on this branch's merge: flipping the skills
writer to putArray left the full 1603-test suite green while silently
deleting the charter entry, which would launch an opencode member with
no role contract at all.

Fix: charter's putArray -> withArray (one-word change, behavior-identical
today). Add three tests asserting instructions[] CONTENT as an exact
ordered list (not size) across writer combinations: charter only,
charter + IDE rules, and charter + IDE rules + seeded skills. Mutation
testing (see PR body) shows the skills and IDE-rules writers are each
independently detectable by name; the charter writer's own mutation is
not detectable by any test, because it structurally always runs first
against an empty array, so putArray and withArray are equivalent there.

Dai Ha d4a2cd720c fleetd #393: deliver memberSkills to opencode members, and stop overclaiming seeding success
CI / contract (pull_request) Successful in 49s
CI / build (pull_request) Successful in 2m46s
GitWorktrees.seedSkills copies memberSkills:-seeded skill folders into every
provisioned worktree's .claude/skills/ and logged "skill seeding: N of M" as
if that were success — but .claude/skills/ is a Claude Code CLI convention.
opencode has no such discovery, so a kind: opencode member never actually
read a seeded skill even though the log said N of M succeeded.

Two changes, both required:

1. Deliver it. OpenCodeLauncher.skillInstructionFiles scans
   <cwd>/.claude/skills/*/SKILL.md at spawn time (the one point the launcher
   knows both the kind and the cwd) and appends each to the generated
   opencode.json's instructions[] array, the same channel already used for
   the member charter and IDE rules. A skill folder with no SKILL.md is
   named and skipped rather than silently dropped.

2. Stop claiming it where the claim can't be verified. GitWorktrees.seedSkills'
   log now says explicitly that consumption depends on the member's kind and
   points at the launcher's own log; OpenCodeLauncher logs its own kind-aware
   "skill delivery: M of N ..." line once the kind is actually known, naming
   any folder it could not turn into an instructions[] entry.

fleetd.example.yaml's memberSkills: doc previously claimed "Claude Code
members only; an opencode member reads a different path (.opencode/agent)
this key does not touch" — false as of this fix, corrected to name both
kinds and how each consumes it.

Tests: OpenCodeLauncherTest gains two cases driving the real
GitWorktrees#add seeding path (not a hand-built fixture) into an
opencode-kind spawn — one asserting a seeded skill's SKILL.md lands in
instructions[] plus the honest log line, one covering a skill folder
without SKILL.md (delivered skills still flow, the malformed one is named
in the log and excluded from instructions[]). ClaudeCodeLauncher is
untouched — its native .claude/skills/ discovery already worked and is out
of scope.
