What changed

T073 only: persist exact runtime/native bindings for canonical winds_sessions(session_id) and resolve only future resume candidates from fresh executable/version evidence. Durable native IDs never establish LIVE or RESUMED on their own.

Scope:

  • migrations/0008_runtime_session_bindings.sql
  • src/agentic_runtime.rs
  • src/store.rs only for migration registration + crate-internal SQLite access
  • src/t073_runtime_binding_tests.rs

Final scope: 4 files, +1046 / -1.

Spec Kit traceability

  • Active spec: specs/006-agentic-terminal-local-delegation-control-plane/spec.md
  • Canonical task: T073 — Runtime-session binding persistence and continuity truth
  • Canonical dependency: T072 CLOSED_CANONICAL
  • T073 closes to authorize T074
  • Acceptance scenarios proven by focused deterministic tests

Review stack and finding reconciliation

  • Author exact-head correctness/safety/evidence-integrity review — PASS
  • Ponytail/YAGNI exact-head review — PASS / no required removals
  • CodeRabbit exact-head status — SUCCESS
  • CodeRabbit final delta review (85a397... -> 09f20e5...) — no actionable comments generated
  • Qodo material correctness finding: non-present runtime incorrectly classified Stale — FIXED / thread resolved by Qodo
  • Qodo material reliability finding: ownership-loss load→update race — FIXED / thread resolved by Qodo
  • CodeRabbit correctness finding: relative executable path could be persisted — FIXED; creation now rejects non-absolute paths and regression coverage proves no row persists
  • Qodo Store raw-connection observation — NON_MATERIAL_MAINTAINABILITY; reconciled/resolved without widening T073 into a Store architecture refactor
  • all inline review threads resolved
  • zero unresolved material findings

Review-note classifications:

  • CodeRabbit walkthrough contains a stale prose risk sentence claiming relative paths may be accepted. That statement is superseded by the exact-head implementation and test: runtime_binding_path_text rejects non-absolute paths before INSERT, and invalid_binding_facts_and_schema_identity_expansion_fail_closed proves the fabricated relative-path binding is rejected. CodeRabbit produced no actionable comment on the final exact-head review and its commit status is SUCCESS. Classification: STALE_SUMMARY_TEXT_NON_ACTIONABLE.
  • CodeRabbit docstring coverage warning: NON_MATERIAL_BOT_STYLE_WARNING; it is not a repository Tasks/CI correctness or safety gate.
  • crate-internal Store.connection visibility and duplicate simple validators: NON_MATERIAL_MAINTAINABILITY; no current semantic divergence or invariant failure is demonstrated.

T073 acceptance / safety invariants

  • binding points to canonical winds_sessions(session_id)
  • concrete runtime kind + exact executable/version provenance persisted
  • optional native ID remains subordinate binding truth
  • no duplicated workspace/workstream identity in binding table
  • no PID/model/provider identity persisted
  • no persisted LIVE or RESUMED state
  • durable ownership vocabulary only UNPROVEN / OWNERSHIP_LOST
  • non-present discovery returns Unavailable, not false stale/resume truth
  • executable/version replacement makes mapping Stale
  • missing native mapping returns Unavailable
  • multiple exact native mappings return deterministic Ambiguous
  • exact native identity cannot silently alias multiple Winds sessions
  • ownership-loss transition is durable, idempotent, and monotonic
  • relative executable provenance rejected before persistence
  • restart/native ID alone never recreates live ownership
  • no blind attach/resume is implemented
  • no real Agent process or prompt
  • no provider/model calls or auth/terms actions
  • no ACP dependency, MCP, daemon IPC, remote execution, or automatic landing

📝 Walkthrough

Walkthrough

The change adds runtime session binding persistence. It stores executable and version provenance, tracks ownership state, validates records, and resolves exact resume candidates. Integration tests cover persistence, stale mappings, ambiguity, ownership loss, identity uniqueness, and schema constraints.

Changes

Runtime session binding

Layer / File(s) Summary
Binding schema and store wiring
migrations/0008_runtime_session_bindings.sql, src/agentic_runtime.rs, src/store.rs
Adds the binding schema, runtime and ownership contracts, and migration initialization.
Binding storage and resume resolution
src/agentic_runtime.rs
Adds validated create, load, list, ownership-loss, and resume-resolution operations with strict persisted-data checks.
Binding integration validation
src/t073_runtime_binding_tests.rs, src/agentic_runtime.rs
Adds integration coverage for persistence, stale and unavailable results, ambiguity, ownership loss, native identity uniqueness, and fail-closed validation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 09f20

The PR persists runtime bindings and resolves future resume candidates only when fresh executable and version evidence matches. A bounded merge-readiness risk remains because relative executable paths may be accepted when stored but rejected later, causing an otherwise valid binding to be skipped; follow-up should also keep binding writes behind validated store operations.

Correctness / safety / evidence-integrity review:

  • Scope is exactly the T073 runtime-session binding slice: migration 0008 + agentic runtime binding logic + minimal Store integration + focused T073 tests.
  • Binding ownership remains subordinate to canonical winds_sessions(session_id); workspace/workstream identity is not duplicated.
  • Persisted identity is bounded to concrete runtime kind, exact executable provenance, exact locally observed version provenance, optional native session ID, and UNPROVEN / OWNERSHIP_LOST durable ownership truth.
  • No PID, model/provider identity, persisted LIVE, RESUMED, Agent execution, prompt, ACP, MCP, daemon IPC, remote execution, or automatic landing is introduced.
  • Exact executable/version drift yields stale applicability; missing native mapping yields unavailable; multiple exact candidates remain explicit/deterministic rather than guessed.
  • Durable native ID never upgrades ownership to live truth after Store reopen.
  • Exact native identity cannot silently alias multiple Winds sessions.
  • Focused T073 tests execute on the exact head and pass on Ubuntu and native Windows.
  • quality #677 = SUCCESS; release-candidate #446 = SUCCESS; windows-terminal #383 same-head rerun closes the prior unrelated Windows process-timing failure without any Spec 003 mutation.

YAGNI / over-engineering review:

  • No new dependency.
  • No generic runtime/plugin abstraction.
  • No ACP/MCP/daemon/public IPC/remote execution layer.
  • No extra migration beyond T073-reserved 0008.
  • No duplicated workspace/workstream identity and no model/provider/PID persistence.
  • src/store.rs changes are limited to crate-internal connection access for the closed T073 module plus migration registration.
  • Persistence/resolution types are task-local and bounded to the explicit T073 acceptance vocabulary (Unavailable, Stale, exact Candidate, deterministic Ambiguous; durable ownership only UNPROVEN/OWNERSHIP_LOST).
  • The Windows Box<RuntimeSessionBinding> change is a narrow representation fix required by exact-platform Clippy and introduces no abstraction or behavioral expansion.

High-Level Assessment

The following are alternative approaches to this PR:

1. Store only latest binding per (session_id, runtime_kind)
  • ➕ Simpler query surface (no history)
  • ➕ Avoids ambiguous multiple candidates by construction
  • ➖ Loses provenance/history needed for debugging and deterministic reasoning
  • ➖ Harder to represent legitimate rebinds over time (e.g., upgrades)
2. Use a natural composite key instead of binding_id
  • ➕ Removes need to generate/manage a separate binding_id
  • ➕ Uniqueness can be fully expressed via schema constraints
  • ➖ Harder to reference a single binding row for updates (e.g., ownership loss)
  • ➖ May require larger indexes and more complex updates/migrations
3. Persist less evidence (e.g., only canonical path + version)
  • ➕ Smaller rows and less coupling to file hashing
  • ➕ Faster inserts and simpler code
  • ➖ Weakens the 'exact match' guarantee; higher risk of incorrect resume candidate
  • ➖ Executable drift detection becomes less reliable

Recommendation: The PR’s approach (separate bindings table + exact executable+hash+version evidence + no persisted LIVE/RESUMED) is the safest fit for T073’s invariants. It preserves deterministic provenance and prevents native IDs from implying live ownership, while still enabling a future-task resume workflow to be built on top.

23-23: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider a shared-reference accessor instead of exposing the field.

pub(crate) connection grants the whole crate both &Connection and &mut Connection. Mutable access permits transaction() from any module, which is wider than what src/agentic_runtime.rs needs. The new binding methods use only shared access.

Keep the field private and add pub(crate) fn connection(&self) -> &Connection. The impl Store block in src/agentic_runtime.rs then keeps working after replacing self.connection with self.connection().

Consider reusing the existing identity validation helpers.

validate_runtime_binding_text and validate_runtime_binding_timestamp duplicate validate_agentic_identity_text and validate_agentic_identity_timestamp in src/store.rs (lines 2187-2199). The bodies and error text are identical. Two copies can drift when one side adds a rule such as a length bound or a control-character check.

Promote the two store.rs helpers to pub(crate) and call them here, or move both pairs into one shared validation module. Keep validate_runtime_binding_sha256 and runtime_binding_path_text local, because they are specific to this feature.

Add coverage for the idempotent and rejected ownership-loss branches.

The test covers only the first successful transition. Three branches in mark_runtime_binding_ownership_lost stay untested:

  • The idempotent repeat at src/agentic_runtime.rs lines 467-475 returns Ok(()) when ownership is already lost and the new timestamp is not earlier.
  • The monotonic rejection at lines 471-473 returns an error for an earlier observation.
  • The pre-binding rejection at lines 464-466 returns an error when observed_unix_ms < bound_unix_ms.
💚 Proposed additional assertions
     store
         .mark_runtime_binding_ownership_lost("binding-1", 60)
         .unwrap();
+    // Repeating the same observation is idempotent.

+        .mark_runtime_binding_ownership_lost("binding-1", 60)

     drop(store);

Note that the third call moves the observation forward, so adjust the later assert_eq!(binding.ownership_observed_unix_ms, Some(60)) to the final expected value, or drop that call and keep only the equal-timestamp repeat.

Independent review reconciliation:

  • Qodo reviewed the exact four-file T073 delta and explicitly recommends the current approach as the safest fit for T073 invariants. No inline Qodo findings/threads are open.
  • CodeRabbit completed its exact-head walkthrough with Merge Risk: Low and states merge is reasonable. No inline CodeRabbit findings/threads are open.
  • CodeRabbit note that an OWNERSHIP_LOST binding may still be returned as a future resume candidate is consistent with T073: Candidate is deliberately neither LIVE nor RESUMED, and T073 performs no attachment/resume. A later execution task must independently re-prove native ownership before any real attachment/resume. Classification: NON_MATERIAL_FUTURE_EXECUTION_GUARD.
  • CodeRabbit docstring coverage warning (53.13% vs its 80% bot threshold) is not a repository Tasks/CI acceptance gate, introduces no correctness/safety/evidence-integrity defect, and would create exact-head churn for documentation-only expansion. Classification: NON_MATERIAL_BOT_STYLE_WARNING.

Action required

1. Unavailable marked as stale ✓ Resolved 🐞 Bug ≡ Correctness
Description
resolve_runtime_resume_candidate returns Stale whenever no exact match is found, but
runtime_binding_matches_discovery rejects all bindings unless discovery is Present, so a
discovery in Unavailable/UnsupportedVersion/VersionUnavailable incorrectly becomes Stale
(even though the runtime may simply be unavailable). This can misclassify the situation and drive
downstream logic to treat bindings as drifted rather than just unusable right now.
Code

src/agentic_runtime.rs[R508-511]

+            .collect::<Vec<_>>();
+        if exact.is_empty() {
+            return Ok(RuntimeResumeResolution::Stale);
+        }
Relevance

●● Moderate

Unavailable-discovery handling is accepted, but no close precedent resolves unavailable states
distinctly from stale bindings.

PR-#73

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The matching predicate requires discovery.state == Present, and the resolution code maps an empty
exact set to Stale, so any non-Present discovery will always produce Stale when there are
stored bindings.

src/agentic_runtime.rs[283-296]
src/agentic_runtime.rs[493-511]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`Store::resolve_runtime_resume_candidate` currently returns `RuntimeResumeResolution::Stale` whenever `exact.is_empty()`. Because `runtime_binding_matches_discovery` hard-requires `discovery.state == RuntimeDiscoveryState::Present`, any discovery state other than `Present` forces `exact` to be empty, making the result `Stale` even when the runtime is simply unavailable or has an unsupported/unavailable version.

### Issue Context
This is a semantic mismatch: `Stale` should indicate bindings exist but do not match a fresh, usable discovery; it should not be emitted when there is no usable discovery.

### Fix Focus Areas
- src/agentic_runtime.rs[283-296]
- src/agentic_runtime.rs[493-511]

### Suggested fix
In `resolve_runtime_resume_candidate`, add an early guard:
- If `discovery.state != RuntimeDiscoveryState::Present`, return `Ok(RuntimeResumeResolution::Unavailable)` (or introduce a distinct resolution variant if you need to preserve `UnsupportedVersion` vs `Unavailable`).

This preserves the meaning of `Stale` for the "present but mismatched" case only.

2. Ownership-loss update race ✓ Resolved 🐞 Bug ☼ Reliability
Description
mark_runtime_binding_ownership_lost loads the binding then updates it with `WHERE ... AND
ownership_state = 'UNPROVEN', and errors if updated != 1`, so a concurrent transition to
OWNERSHIP_LOST between the load and update causes a spurious error. This makes the operation
non-idempotent and fragile under multi-process or retry scenarios.

Evidence
The UPDATE is conditioned on ownership_state = UNPROVEN and the function errors when the UPDATE
affects 0 rows, which will happen if another writer transitions the row after the initial read.

PR-#58

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`Store::mark_runtime_binding_ownership_lost` can fail with `"runtime ownership-loss transition lost its unproven binding row"` if another writer updates the row after the initial load but before the UPDATE executes. This is a classic load→check→update race that turns a benign concurrent update into an error.

### Issue Context
Even if today only one process is expected to write, future reconciliation paths or retries can trigger this. The code already treats repeated transitions as OK (when detected at load time), but not when the change happens after the load.

### Fix Focus Areas
- src/agentic_runtime.rs[453-490]

### Suggested fix
Make the DB operation idempotent:
1) Attempt an UPDATE that sets `OWNERSHIP_LOST` only when the row is not already `OWNERSHIP_LOST`.
2) If `updated == 0`, re-load the binding and:
  - If it is already `OWNERSHIP_LOST`, enforce monotonicity against the stored `ownership_observed_unix_ms` and return Ok.
  - Otherwise return an error.

This preserves monotonic guarantees while eliminating spurious failures under concurrency.

3. Store DB field exposed 🐞 Bug ⚙ Maintainability
Description
Changing Store.connection to pub(crate) broadens access to raw SQLite operations across the
crate, making it easier for new code to bypass Store invariants and increasing coupling to internal
schema details. This raises long-term maintenance risk and makes future Store refactors harder.

Evidence
The diff explicitly changes the Store struct field visibility to pub(crate), which allows any
crate module to directly run SQL on the connection.

src/store.rs[20-26]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`Store.connection` was made `pub(crate)`, exposing the raw `rusqlite::Connection` to all crate modules. This weakens encapsulation and makes it easier to accidentally bypass Store-level invariants.

### Issue Context
The immediate motivation appears to be enabling runtime-binding persistence from outside `store.rs`. In Rust, keeping the field private while adding narrowly-scoped APIs (or moving the impl into `store.rs` / a `store::*` submodule) preserves encapsulation.

### Fix Focus Areas
- src/store.rs[20-26]
- src/agentic_runtime.rs[316-525]

### Suggested fix
Prefer one of:
- Move the `impl Store { ...runtime_session_bindings... }` block into `src/store.rs` (or a `src/store_runtime_bindings.rs` module declared as a submodule of `store`), so it can access the private field.
- Keep `connection` private and add a minimal `pub(crate)` accessor method (ideally test-only behind `#[cfg(test)]` if that’s the only need).

Goal: reduce the blast radius of direct SQL access while keeping required functionality.

640-643: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject relative executable paths before persistence.

runtime_binding_path_text only validates UTF-8. create_runtime_session_binding can therefore persist a relative path, but runtime_binding_from_stored_row rejects that row at Line 575. A later listing or resume resolution then fails for the session/runtime instead of returning a resolution.

Require Path::is_absolute() before inserting the binding. Add a test that uses a relative executable path and asserts that binding creation fails.

Proposed fix
 fn runtime_binding_path_text<'a>(path: &'a Path, label: &str) -> StoreResult<&'a str> {
+    if !path.is_absolute() {
+        return Err(format!("{label} runtime executable path must be absolute").into());
+    }
     path.to_str()
         .ok_or_else(|| format!("{label} runtime executable path is not valid UTF-8").into())
 }

T073_QODO_REVIEW_RECONCILIATION — current exact candidate 85a397bb899ec6ea6894178ee7ecae9b67ddead3

  1. Unavailable marked as stale — FIXED. resolve_runtime_resume_candidate now returns Unavailable immediately for any fresh discovery that is not Present; Stale is reserved for a present runtime whose exact persisted executable/version evidence no longer matches. Exact-head focused test missing_or_non_present_mapping_is_unavailable_not_resumed executes and passes.

  2. Ownership-loss update race — FIXED. The transition is now a single idempotent SQL update with monotonic timestamp guard plus fail-closed reload fallback. Repeated same/later ownership-loss observations succeed without changing the first durable observation time; regressed observations are rejected. Exact-head focused ownership-loss test executes and passes. Qodo has automatically resolved both material threads after the repair.

  3. Store db field exposed — classified NON_MATERIAL_MAINTAINABILITY_YAGNI. Store::connection is crate-internal (pub(crate)), not public API, and the current access is limited to the closed T073 runtime-binding implementation. No invariant bypass, correctness defect, protocol expansion, or unauthorized caller is demonstrated. Moving hundreds of lines into store.rs, creating another Store submodule, or adding an accessor solely to hide the same crate-internal capability would enlarge T073 without improving its proven safety semantics. Retain the minimal current split and keep future raw-SQL access subject to normal review.

No correctness/safety finding is waived. The remaining maintainability thread is accepted as non-material for T073 qualification.

T073 exact-head author / Ponytail review

Reviewed exact candidate:
09f20e5adadb2e16b637e8879ac4a7b55b0d6ed1

Canonical base:
1404a580ff1168387e0ed61c2644b7508bb399aa

Scope remains exactly four T073 files. The final tree preserves canonical Workspace -> Workstream -> Winds session identity and keeps runtime/native identity subordinate to winds_sessions(session_id). It persists no workspace/workstream duplication, PID, model, provider, LIVE, or RESUMED truth. Non-present discovery fails closed to Unavailable; executable/version drift produces Stale; exact ambiguity stays deterministic; native IDs remain future resume candidates only; ownership-loss persistence is idempotent/monotonic; relative executable provenance is rejected before persistence.

The final repairs address the material review findings without adding an execution protocol, Agent execution, provider calls, ACP, MCP, daemon IPC, remote execution, automatic landing, or new dependencies. The remaining Store encapsulation / duplicated simple-validator observations are maintainability-only and do not demonstrate a current correctness or safety defect; widening this task into a Store refactor would be unnecessary scope expansion.
