📝 WalkthroughWalkthroughThe change adds configurable session history for terminal execution and explicit commands. It records bounded output, sanitizes persisted arguments, stores hashed manifests and blobs, enforces quotas, and disables history by default. ChangesSession history
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds local persistence for command metadata and opt-in terminal output. At the current head, credential-bearing URL arguments can still be stored, disable behavior differs between execution paths, incomplete reads can be recorded as complete, and history filesystem work can block unrelated state writes. These bounded but concrete privacy, correctness, and availability risks should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

T056 author correctness / safety / privacy review — exact head 5640589ac92de1847fdb38e515e9d1c7f05a2a9d
PASS. No actionable correctness, safety, privacy, or active-spec issue remains in this author pass.
Reviewed specifically:
- Transcript persistence is explicit opt-in; normal terminal launches keep transcript/history disabled.
- Retention has both a hard per-session transcript cap (8 MiB maximum) and an explicit total local-history byte quota; repeated-session fixtures exercise pruning so retained history cannot grow without the configured bound.
- Prune/write is serialized across Winds processes sharing the same state database via a short
BEGIN IMMEDIATEguard. No history row is added to candidate/evidence/eligibility/promotion tables and the transaction is rolled back after the filesystem operation. - The supplied state root fails closed unless it contains a real
winds.dband the exact execution id exists there asTERMINAL; wrong-root persistence is covered by a negative fixture. - Transcript completeness is truthful: persistence before an output reader is captured is rejected, early reader drop records
capture_complete=falseandtruncated=true, and EOF is required for a complete-capture claim. - Live PTY output remains unchanged; only the bounded retained copy is persisted.
- History files use SHA-256-derived session identity, create-new semantics, fail closed on symlink/unrecognized history entries, and use 0700/0600 creation modes on Unix. Windows inherits the state directory ACL rather than making an unsupported POSIX-mode claim.
- Explicit-command execution still receives the original argv. Persisted command metadata is separately best-effort redacted; callers can disable persisted command arguments entirely with the history-disabled placeholder.
- Secret filtering is deliberately labeled best-effort and is not represented as secret detection. Transcript contents may still contain secrets, which is why transcript persistence is local, bounded, explicit opt-in, and default-off.
- No full environment-value snapshot is introduced. Existing sanitized clone-origin persistence from T046 remains unchanged.
- T055 BEFORE/AFTER Git observation ordering and durable command-exit semantics are unchanged.
- Local history is workspace/session history only and cannot become verification eligibility evidence.
- T057 timeline/history read UX remains deferred; no daemon, public IPC/protocol, plugin/provider abstraction, MCP/ACP/A2A, or Agent Fleet scope was introduced.
Exact-head gates at review time: quality #339 PASS, windows-terminal #116 PASS, release-candidate #186 PASS including SC-001 100-cycle soak and Linux/macOS release bundles.

T056 Ponytail v4.9.0 simplicity review — exact head 5640589ac92de1847fdb38e515e9d1c7f05a2a9d
PASS. No actionable simplicity issue remains in this author pass.
Simplicity findings:
- Three source paths only:
src/command.rs,src/command/history.rs, andsrc/execution.rs. - No new dependency, SQLite migration, workflow, daemon, service, public protocol, plugin/provider layer, MCP/ACP/A2A surface, renderer, environment manager, or Agent Fleet machinery.
- Reuses the existing execution ledger and rusqlite/sha2 dependencies; history payloads stay in a dedicated local filesystem area rather than widening verification/evidence schema.
- One typed
SessionHistoryPolicyowns disable/per-session/total-quota decisions. - One typed
LocalTerminalHistorygroups opt-in terminal-history configuration instead of adding unrelated positional launch arguments or a generic options framework. - One reader wrapper performs bounded retention without changing the live PTY stream.
- One short SQLite write-lock seam serializes cross-process quota/prune/write; it does not create a second database or persistence subsystem.
- Anticipatory T057 history loader/timeline APIs created during an earlier iteration were removed before this head.
- The relatively large
history.rsis dominated by fail-closed filesystem/privacy logic and direct deterministic tests for the T056 requirements; splitting it into speculative service/repository/policy layers would increase indirection without reducing authority or complexity.
No custom multiplexer, checkpoint/ref mechanism, shell hook, PTY keystroke parser, secret-scanner framework, background cleaner, or generic retention engine was introduced.

T056 author correctness / safety / privacy review — exact head 95e5c969e79898fa3b208df9492b61b30a98fbe6
PASS. No actionable correctness, safety, privacy, or active-Spec-003 issue remains in this author pass.
Reviewed specifically:
- Transcript persistence remains explicit opt-in; normal terminal launches remain transcript-disabled.
- Command metadata and transcript policy are separate but both honor the per-session policy. Native and WSL terminal persistence now route shell arguments through the policy-aware persistence path while runtime launch arguments remain unchanged.
- The prior recorder finalization race is removed: reader lifecycle is represented under the same mutex as transcript state, and persistence fails closed while the output reader is active.
- Empty-buffer reads no longer fabricate EOF or capture completeness; early reader drop remains explicitly incomplete/truncated.
- Total-history quota accounting includes the serialized manifest. When transcript retention would consume mandatory metadata space, retained transcript bytes are reduced and truncation remains explicit; accepted policies are checked for mandatory-metadata feasibility.
- The 8 MiB value is now described only as a Winds implementation safety maximum, not as a Spec 003 or privacy guarantee.
- Best-effort metadata redaction now conservatively redacts composite arguments containing credential-bearing or query/fragment-bearing URL-like tokens without claiming general secret detection.
- History persistence requires the exact TERMINAL execution plus its typed
terminal_sessionsrow in the supplied real Winds state root. - Recursive production history deletion now passes through one ownership helper that rejects symlinks, the history root itself, outside-root targets, and unrecognized session identities before
remove_dir_all. - Manifest path/byte-count/SHA integrity is regression-tested in addition to transcript integrity.
- History remains local workspace/session history. No candidate evidence, BlobEvidence, eligibility, promotion, or
winds verifyauthority was introduced. - No full environment snapshot, schema migration, dependency, daemon/server/socket, public protocol, MCP/ACP/A2A, plugin runtime, Agent Fleet, or T057 timeline/CLI scope was introduced.

T056 Ponytail v4.9.0 simplicity review — exact head 95e5c969e79898fa3b208df9492b61b30a98fbe6
PASS. No actionable over-engineering issue remains in this author pass.
Simplicity findings:
- PR remains confined to the same three source paths:
src/command.rs,src/command/history.rs, andsrc/execution.rs. - No new dependency, migration, workflow, service, daemon, IPC/public protocol, plugin/provider framework, MCP/ACP/A2A surface, renderer, background cleaner, or Fleet machinery.
LocalTerminalHistoryand its opt-in entrypoints were narrowed topub(crate)rather than creating a public extension API before T057.- One
SessionHistoryPolicyowns command/transcript enablement and quotas; one reader wrapper owns bounded capture; one narrow deletion helper owns recursive history cleanup checks. - The finalization-race repair uses an existing mutex-protected state bit instead of atomics/channels/background synchronization.
- Quota reconciliation reuses the existing manifest representation and truncates the retained copy rather than adding a second quota subsystem or database schema.
- URL handling remains deliberately conservative best-effort metadata redaction; no shell parser or secret-scanner framework was introduced.
- The retained 8 MiB ceiling is a small defensive allocation bound. Removing every implementation ceiling would permit caller-selected in-memory retention up to arbitrary
usize; replacing it with streaming/ring infrastructure would be more complex and is not justified by T056. - The output reader must be final before persistence because completeness/truncation metadata must be final. Adding a blocking finalize/background coordination API before a production T057 caller exists would be speculative; the current fail-closed contract is simpler and truthful.
- Direct reuse of the candidate
Store::write_blob/BlobEvidencesemantic API remains avoided so local history cannot acquire verification-evidence meaning.
Nothing in this head pulls T057, Agent Fleet, persistent detached sessions, or a generic terminal/history ecosystem into T056.

T056 review-thread reconciliation — exact head Current deterministic evidence: quality #342 PASS; windows-terminal #119 PASS; release-candidate #189 PASS; SC-001 100-cycle soak PASS; Linux/macOS release bundles PASS. Reconciliation of the remaining pre-repair threads:
The prior Cubic race, quota, typed-terminal-row, and zero-read findings and the prior Qodo delete-ownership, composite-URL, quota, public-surface, and zero-read findings are already resolved/outdated after the corresponding fixes. No thread is being resolved merely because CI is green; the classifications above are based on the repaired exact-head behavior and the active T056 boundary. |

T056 author correctness / safety / privacy review — exact head 35141774825701ebe744ce25adf1dab03d17613e
PASS. No actionable correctness, safety, privacy, or active-Spec-003 issue remains in this author pass.
Reviewed specifically:
- Transcript persistence remains explicit opt-in and default-off for normal terminal launches.
- Runtime argv remains unchanged; only persisted metadata is policy-aware and best-effort redacted.
- Disabled command history withholds persisted terminal/explicit-command arguments; enabled command history now has focused sanitizer coverage.
- Composite URL-like metadata with credentials/query/fragment is conservatively redacted, including angle-bracket-delimited URL tokens, without claiming perfect secret detection.
- Transcript completion/truncation truth remains fail-closed for empty reads, early reader drop, active reader persistence, and pre-capture persistence.
- Per-session and total quota accounting includes mandatory manifest bytes and bounded retained transcript bytes.
- History persistence requires a real Winds state root plus exact TERMINAL execution and typed
terminal_sessionsidentity. - The prior major stability issue is repaired:
winds.dbis held only for a short terminal-identity validation transaction. Filesystem prune/write/fsync is serialized separately using a local SQLite lock-carrier file that has no application/history/evidence schema or rows. - A regression enters the history filesystem critical section and successfully acquires a separate
BEGIN IMMEDIATEtransaction onwinds.db, proving the history critical section no longer occupies the primary database writer lock. - The lock carrier rejects symlinks/non-files and uses private creation mode on Unix. SQLite/OS transaction ownership provides crash release without a stale PID ownership protocol.
- Recursive pruning still validates canonical owned-session descendants immediately before recursive deletion.
- History artifacts and lock coordination remain local workspace/session mechanics and do not become candidate evidence, eligibility, promotion, or
winds verifyauthority. - No dependency, schema migration, daemon/server/socket, public protocol, plugin/provider framework, MCP/ACP/A2A, Agent Fleet, T057, or T058+ scope was introduced.
Exact-head deterministic evidence: quality #344 PASS; windows-terminal #121 PASS; release-candidate #191 PASS; SC-001 100-cycle soak PASS; Linux x86-64 and macOS arm64 release bundles PASS.

T056 Ponytail v4.9.0 simplicity review — exact head 35141774825701ebe744ce25adf1dab03d17613e
PASS. No actionable over-engineering issue remains in this author pass.
Simplicity findings:
- The PR remains confined to the same three source paths:
src/command.rs,src/command/history.rs, andsrc/execution.rs. - No new dependency, schema migration, workflow, daemon, public IPC/runtime protocol, plugin/provider abstraction, MCP/ACP/A2A, renderer, or Agent Fleet machinery.
- The main-database lock repair does not introduce a lock library, lock daemon, PID protocol, or new application database. It reuses the already-present SQLite runtime as a tiny coordination-only lock carrier while releasing
winds.dbbefore filesystem work. - The lock carrier contains no application tables or product truth; it exists only to serialize cross-process history filesystem mutation and relies on transaction lifetime for crash cleanup.
- A single helper owns minimum-manifest sizing instead of duplicating the probe construction.
- URL delimiter handling remains a small conservative token trim rather than adding a shell parser or URL/secret-scanner framework.
- Existing
SessionHistoryPolicy, reader wrapper, quota/prune path, and owned-delete helper remain the only history abstractions. - T057 timeline/CLI, future multi-agent orchestration, detached session service, checkpoint/ref rewind, model routing, MCP, and provider ecosystems remain explicitly outside this slice.
The repaired head preserves the T056 product boundary while removing a real concurrency hazard with the smallest robust cross-process mechanism available in the current dependency set.

I verified the requested T056 controls by static review. This includes default-off transcript persistence, disabled command-history metadata, bounded capture and retention pruning, separate The PR range changes only the three expected Rust files. It does not modify T046 clone-origin sanitation. It does not add excluded T057, daemon, protocol, plugin, Agent Fleet, dependency, workflow, or migration scope. The sandbox did not execute tests.

1. Shell args persisted as winds:history-disabled 📘 Rule violation ⚙ Maintainability
terminal_sessions.shell_arguments is now populated via `persisted_arguments(.., history.policy())`, so the default disabled history policy replaces exact launch arguments with <winds:history-disabled>. This introduces persisted behavior that is not described (and appears to conflict with the spec’s requirement for exact executable/argument identity in shell profiles/terminal session records).
Agent Prompt
## Issue description
`terminal_sessions.shell_arguments` is derived from `SessionHistoryPolicy` via `persisted_arguments(...)`, which can replace the real shell launch arguments with `<winds:history-disabled>` by default. This makes terminal session identity less exact than the active Spec 003 documents describe.
## Issue Context
Spec 003 documents describe shell profile and terminal session identity as requiring exact executable/argument identity, while the new implementation gates persisted `shell_arguments` on history policy.

2. First history writes race 🐞 Bug ☼ Reliability
with_history_write_lock initializes the shared history directory before acquiring the cross-process SQLite lock. Concurrent first writers can both observe it absent, causing one valid persistence attempt to fail with AlreadyExists.
Agent Prompt
## Issue description
Concurrent processes can race while creating the history root before filesystem-write serialization begins.
## Issue Context
`ensure_private_directory` uses a check-then-create sequence and propagates `AlreadyExists`, while the SQLite transaction is acquired only afterward.

3. Successful history reports failure 🐞 Bug ☼ Reliability
If the transcript operation succeeds but rolling back the lock-carrier transaction fails, persist returns an error without marking the recorder persisted. The files already exist, so every retry is then rejected as a duplicate and the caller never receives their artifact references.
Agent Prompt
## Issue description
A lock-release error after successful filesystem persistence creates an ambiguous success that cannot be retried.
## Issue Context
Filesystem output is complete before `ROLLBACK`, but recorder state and returned artifact references are only finalized after `with_history_write_lock` returns successfully.

4. Non-utf8 temp path panics 🐞 Bug ⚙ Maintainability
The new incomplete-terminal-row test unwraps UTF-8 conversion of a temp-directory-derived workspace path. On Unix, a valid non-UTF-8 temporary path therefore panics before the history rejection behavior is tested.
Agent Prompt
## Issue description
The new Unix-compatible test assumes a temp-derived filesystem path is valid UTF-8 and can panic in valid environments.
## Issue Context
Unix paths may contain arbitrary bytes; avoid unconditional `to_str().unwrap()` in tests or explicitly skip/propagate when the persistence schema requires UTF-8.

5. Inconsistent manifest size estimate for quota check 🐞 Bug ≡ Correctness
SessionHistoryPolicy::local_bounded() estimates the mandatory manifest size using a fake 1-byte
execution_id ("x"), while SessionHistoryRecorder::new() re-checks the same quota using the real
execution_id (up to 512 bytes). A policy can pass local_bounded() validation but still be rejected
at recorder construction time for execution IDs long enough to push the real manifest size above the
total quota, making the policy-level validation an unreliable pre-check.
Agent Prompt
## Issue description
`SessionHistoryPolicy::local_bounded()` validates that the total quota can hold mandatory manifest metadata using a placeholder execution_id of length 1 (`"x"`), while the real recorder-construction check in `SessionHistoryRecorder::new()` uses the actual execution_id, which can be up to `MAX_EXECUTION_ID_BYTES` (512) bytes long. This means a policy can be accepted by `local_bounded()` but rejected later when actually constructing a recorder for a long execution_id, since the manifest's serialized size grows with the execution_id length.
## Issue Context
`minimum_manifest_bytes` builds a manifest with a zero-length transcript and the given execution_id to compute the minimum bytes required for the mandatory manifest. `local_bounded()` only has access to the quota values, not a specific execution_id, so it uses a placeholder. The recorder constructor performs the authoritative check with the real ID.
## Fix Focus Areas
- src/command/history.rs[48-77] (SessionHistoryPolicy::local_bounded quota pre-check should use a worst-case/maximum-length execution_id, e.g. MAX_EXECUTION_ID_BYTES worth of placeholder characters, instead of a single character, so accepted policies remain valid for any legal execution_id)
- src/command/history.rs[149-170] (SessionHistoryRecorder::new performs the authoritative check with the real execution_id; ensure the policy-level pre-check in local_bounded is consistent with this so callers get an early, accurate error instead of a later surprising rejection)

Spec 003 / T056
Implements only the T056 bounded local history/transcript retention and privacy-policy slice.
Scope
winds.dbmust be a real file and contain the matchingTERMINALexecution plus typedterminal_sessionsrowwinds.dbtransaction that is released before filesystem prune/write/fsync beginsPrivacy and authority boundary
This does not claim perfect secret detection. Transcript contents may still contain secrets, which is why transcript persistence is local, bounded, explicit opt-in, and default-off.
The 8 MiB value is an implementation allocation-safety ceiling, not a Spec 003 requirement, privacy guarantee, or public quota contract. Canonical T056 requires bounded storage/quota but does not prescribe this number.
