+Run records survive console restarts, but remain local operator state rather
+than a signed release artifact or the system audit log. The default location is
+`$XDG_STATE_HOME/govoplan/release-console/workspace-<sha256>/release-runs/`, or
+`~/.local/state/...` when `XDG_STATE_HOME` is unset or relative. It is outside
+the source checkout so filesystems without enforceable POSIX modes cannot
+silently weaken the journal. Newly created state directories use mode `0700`
+and records use `0600`. Writes use a cross-process lock, a same-directory
+temporary file, `fsync`, atomic replacement, and directory/parent `fsync`.

-The default store belongs to the selected workspace: the console uses that
-workspace's meta checkout when it is available, or a stable workspace-digest
-namespace below this checkout's runtime directory otherwise. The same digest is
-part of the immutable input snapshot. An alternate workspace therefore cannot
-silently list or resume another workspace's runs. `run_state_root` remains an
-explicit embedding/test override.
+The full resolved-workspace SHA-256 is part of both the private storage
+namespace and immutable input snapshot. Every list, read, and state transition
+checks it. An alternate workspace therefore cannot list or resume another
+workspace's runs even when an embedding/test `run_state_root` override is
+shared accidentally.
 
 Each frozen plan step has an explicit `pending`, `running`, `succeeded`,
 `failed`, or `interrupted` state. Plan order remains a prerequisite: a later
 step is unavailable until earlier steps have succeeded. Exact attempt and
-resume/retry request identifiers are fingerprinted so repeated state commands
-are idempotent. The record keeps at most 256 server-generated state events and
-128 request fingerprints. Events contain only an enum event type, timestamp,
-step identifier, and bounded result code—never commands, process output,
-confirmation text, credentials, bearer tokens, or signing material.
+resume/retry/reconciliation request identifiers are fingerprinted so delayed
+repetitions remain idempotent for the run's lifetime. These fingerprints are
+never evicted: the store fails closed before accepting more than 2,048 commands
+or 2,048 attempts and asks the operator to create a fresh run. The display

 An explicit resume after a process restart converts every persisted `running`
 step to `interrupted`; it never guesses whether an external effect happened.
 An interrupted read-only step can be prepared for retry. An interrupted
-mutating step remains unavailable until the operator has reconciled local and
-remote state and explicitly records that reconciliation when preparing the
-retry. A known failed attempt can likewise be prepared for retry. The UI keeps
-the retry control visible and explains why it is disabled when retry is unsafe.

+effect, and `unresolved` keeps the run blocked. Each outcome emits a bounded,
+code-only state event. A known failed attempt can likewise be prepared for
