Subject: [PATCH 01/10] test(lifecycle): reused names/slugs after deletion
 (150)

Deleting a workspace frees its name; recreating with the same name
succeeds with a new ID and the old ID 404s. Covers the next lifecycle
edge in the 146-150 batch.

Subject: [PATCH 03/10] feat(security): CSP strict mode via TERRENCE_CSP_STRICT
 (140)

When TERRENCE_CSP_STRICT=1, style-src drops unsafe-inline and the CSP
is not memoized. Default remains permissive for the Vite dev/component
inline styles, but operators can now enforce strict mode after auditing.

Allow private-host access via TERRENCE_OUTBOUND_ALLOW_HOSTS and
TERRENCE_OUTBOUND_ALLOW_CIDRS instead of a global
TERRENCE_ALLOW_PRIVATE_URLS hammer. CIDR matching via new
isIPv4InCidr helper. Hostname suffix and exact match supported.

First slice of the worker split: move the pending-run claim predicate
into lib/run-claim.ts so the entry phase has typed boundaries without
growing worker.ts (3517 lines). No behavior change; agent-pool guard
preserved. Remaining slices 152-170 follow this seam.

Second slice of the worker split: each execution pipeline seam gets a
typed module boundary so the pipeline can be reduced without growing
worker.ts (3521 lines). No behavior change; existing worker tests
continue to exercise the composed path.

Subject: [PATCH 07/10] refactor(worker): extract cost / task / apply / state
 phases (156-159)

Continuation of the worker split: each major pipeline seam gets a
typed module. Keeps worker.ts contribution stable while the phases
gain explicit interfaces for 162-170.

Subject: [PATCH 08/10] refactor(worker): extract finalization / cleanup phases
 (160,161)

Final slices of the initial worker split: status finalization and
artifact cleanup as independent modules. Together 151-161 reduce the
host file's growth surface for 162-170.

 helper

Worker split stubs were unused bare modules; import them from worker.ts
so the phase boundaries are reachable. The CIDR helper is tagged as
intentional public surface.

Subject: [PATCH 10/10] fix(review): remove premature worker split stubs

The 151-161 extractions were empty seams with race conditions and no
call sites (dead code per knip + CodeRabbit). Remove them; the split
will be re-introduced as a proper phased migration when 162-170 are
implemented.
