Migration 072 adds projects.sandbox_extensions (jsonb null): a per-service
extension/module map a venture declares up front (e.g. {"postgres":
["vector","postgis"],"redis":["search"]}). Additive + nullable so
existing opted-in projects stay byte-for-byte bare — no default set, opters
set the extensions they need explicitly (TimescaleDB out unless asked).
Project model validates the map against SANDBOX_ENGINE_FEATURES: unknown
service keys and unallowed features are rejected at the model boundary with
the allowlist named (plpython3u — superuser-RCE — excluded by construction),
empty feature lists drop to bare, order normalized + deduped. The allowlist
is the security containment, not privilege. Mirrors sandbox_services: not on
ProjectCreate, only Project + ProjectUpdate.
request_sandbox gains an extensions arg; _sandbox_features_scope unions a
per-call override with the project's standing set (trusted), bounds it to the
opted set + allowlist, rejects a non-opted service or unallowed feature with
the allowlist named in remediate — scope-first priority preserved by
rej_scope or rej_features. ensure_sandbox threads features through to
provision(); cache-by-features: a cached entry satisfies a new call iff
services are a subset AND every requested feature per service is already
cached — a feature superset re-provisions (rotates creds), mirroring the
services-superset case. available_extensions rides the evidence payload so an
agent doesn't guess what was activated.
Gate: ruff clean, mypy clean (9 modules), 51 tests pass (incl. migration
round-trip).
* feat(sandbox): on-demand request_sandbox verb replaces eager provisioning
Sandboxes were provisioned at every agent spawn for opted-in projects,
so every role paid the sidecar spin-up and a provisioning failure
refused the spawn. Provisioning now happens when an agent asks: the
request_sandbox do-verb (dev + QA) reaches the orchestrator through
ContentActionsDeps, ensure_sandbox provisions idempotently with an
in-memory per-agent cache (evicted at teardown and janitor sweep), and
creds return in the envelope payload including ready-to-export
ROBOCO_TEST_* values. Spawn now only injects a marker env naming the
available services plus a briefing line; sandbox failures can no longer
refuse a spawn. Teardown lifecycle unchanged.
* feat(sandbox): harden request_sandbox + Phase 3 wiring proof and docs
Hardening from adversarial review: ensure_sandbox now provisions the
project's full opted-in set on first request (a later superset can
never tear down a live sandbox mid-use), serializes per-agent behind an
asyncio lock (a client timeout-retry no longer races its own in-flight
provision), and verifies container liveness on every cache hit (a dead
sandbox evicts and re-provisions instead of serving dead creds). MCP
client budget 720->1080s for the full-set cold case. Phase 3: e2e smoke
wiring test (manifest grants + guard-chain envelopes over the real
API), sandbox-db/tools/map docs and CLAUDE.md rewritten for on-demand.
* feat(sandbox): release sandboxes when the agent's work ends
CEO directive: sidecars must not dangle once the agent is done. The six
work-ending verbs (i_am_done, unclaim, i_am_idle, pass_review,
fail_review, i_documented) now release the caller's sandbox best-effort
on their success path via release_sandbox (lock + teardown + cache
evict; a no-sandbox agent costs a dict lookup). Container removal and
the janitor remain the backstop; a re-request provisions fresh.
* test(sandbox): monkeypatch the release hook instead of method assignment
mypy method-assign rejected the direct AsyncMock assignments; the prior
static gate ran before this test file landed.
* test(sandbox): guard envelope evidence for mypy in verb tests
* chore(prompts): regenerate verb tables for request_sandbox
* chore: resolve merge with master (breadcrumbs + statement budget)
