Adds optional per-script overrides for the six Rhai sandbox knobs
(max_operations, max_string_size, max_array_size, max_map_size,
max_call_levels, max_expr_depth). The executor merges its defaults
with each script's overrides on every call; the manager validates
overrides against an admin-set ceiling at write time, so the
executor trusts whatever is stored.
Storage chose JSONB on the existing scripts table over six new
columns: lets future knobs land as code-only changes, keeps the
sparse common case (most scripts override nothing) cheap to store
and serialize, and matches how the manager + executor pass the
config across the wire.
* 0002_sandbox.sql — ALTER TABLE scripts ADD COLUMN sandbox
JSONB NOT NULL DEFAULT '{}'
* shared::ScriptSandbox — six Option<u64> fields with
deny_unknown_fields so typos surface as 422
* Script.sandbox + ExecRequest.sandbox_overrides — typed end
to end; cluster mode just serializes the same struct
* executor-core::Limits::with_overrides — field-by-field
replacement; tests cover the override actually tightening
the live engine
* manager-core::SandboxCeiling — built-in conservative
defaults (10M ops, 1 MiB strings, 100k array/map, 128
call/expr depth); env vars override per knob, invalid
values warn-and-skip rather than blocking boot
* manager-core admin API — POST/PUT accept `sandbox`; values
above the ceiling return 422 with the specific field +
requested + ceiling; absent or `{}` keeps platform defaults
* picloud all-in-one — wires SandboxCeiling::from_env() into
AdminState
* memory_limit_mb stays in the schema, marked v1.3+ advisory
(no enforcement until OS-level isolation lands with
cluster-mode executors)
Verified live through Caddy:
* /version reports schema 2, product 0.3.0
* Script with max_operations: 500 → 507 on a 10k-iteration loop
* Same script after PUT raising to 1M → succeeds, returns 10000
* POST with max_operations: 1_000_000_000 → 422 (exceeds ceiling)
Tests:
* 13 executor-core unit tests (added 2 for override semantics)
* 20 integration tests (added 6 for sandbox CRUD + ceiling +
unknown-field rejection + executor honoring overrides)
* default cargo test --workspace stays green (integration tests
remain #[ignore]'d until DATABASE_URL is set)
Bumps:
* schema 1 → 2
* product 0.2.0 → 0.3.0
* SDK unchanged (scripts see nothing new)

Sets up the PiCloud monorepo as a Cargo workspace organised around the
three-service architecture (manager / orchestrator / executor), each
backed by a *-core library crate so the same logic powers both the MVP
all-in-one `picloud` binary and the future split-process cluster mode.
* crates/shared, executor-core, orchestrator-core, manager-core
define the library surface and trait seams between the three
services (`ExecutorClient`, `ScriptResolver`, `ScriptRepository`).
* crates/picloud is the MVP entrypoint; serves /healthz on 8080
(override via PICLOUD_BIND).
* crates/picloud-{manager,orchestrator,executor} are skeleton
binaries that keep the crate boundaries honest until cluster
mode is built out in v1.3+.
* docs/git-workflow.md defines the trunk-based workflow:
short-lived branches, Conventional Commits, separate hotfix
flow with mandatory reproduction tests.
* CLAUDE.md captures the working rules for future Claude sessions.
Workspace passes `cargo fmt`, `cargo clippy -D warnings` (with
pedantic enabled), and `cargo test --workspace`. The all-in-one
binary responds on `/healthz` and `/`.
