Implements Phase 2 request preview, authorization, and workflow initiation for the web console (Closes#643).
Operators had to paste a role prompt into a terminal to start work, and nothing enforced that the allocator had been consulted first, so two sessions could reach for the same issue and each believe it was theirs. This adds a request surface: a desired role, an issue or PR, and a stated intent, answered by an authorization decision and, on confirmation, an exclusive assignment from the allocator.
Preview shows authorize/deny with reasons. Five named checks, each with its own verdict, reason code, and detail: authorization, capability, lease_availability, next_safe_action, head_pin.
Apply creates an exclusive assignment or returns wait/blocked. Outcomes are assigned_work (201), wait (409), blocked (409), denied (403), invalid_request (400), evidence_unavailable (503).
Duplicate assign rejected. An active claim on the work unit, held by any session, blocks before an assignment is attempted.
Tests for preview/apply/deny/collision. 52 new tests across eight classes.
UI never shows full secrets; brief user messaging. Every interpolated value is escaped; the intent travels through the standard redaction pass before persistence.
Design notes for the reviewer
Apply runs the allocator twice, on purpose. The allocator is the only source of exclusive ownership (#600/#613), and it selects work rather than taking orders. So apply runs a dry-run first and proceeds only when the allocator would independently pick the requested work unit; otherwise it returns wait and mutates nothing. The apply call carries the dry-run's candidate_set_fingerprint as a CAS pin (#776), and the result is re-checked on the way out so an assignment naming a different work unit is not read as success.
The execution gate is action-scoped, not a phase bump.console_authz.ConsoleAction gains an optional execution_env_flag, and authorize now computes execution_enabled via a new execution_wired(action, env) helper. Raising ACTIVE_PHASE would have enabled execution for every phase-2 action at once, including system.restart_namespace and the analytics ingest, whose execution paths are not implemented here. initiate_workflow is the only action declaring a flag (WEBUI_REQUESTS_EXECUTION); every other action keeps its previous behaviour and still reports execution_enabled: false.
Operator-class authority.initiate_workflow requires operator because its outcome is a claim, not a Gitea verdict. Requesting reviewer or merger work reserves that work; it grants no right to approve or merge, which stays with the MCP role profile.
A denial is not a queue oracle. An unauthorized principal never reaches the allocator or the control-plane DB at all.
Fail-closed behaviour
An unreadable control-plane DB, an incomplete queue inventory (#758), an allocator that raises, an unpinned PR head, a PR head that moved, and an unconfirmed apply all deny without mutating. An unreadable claim inventory is never treated as "nothing holds this work unit".

## Summary
Implements Phase 2 request preview, authorization, and workflow initiation for the web console (Closes #643).
Operators had to paste a role prompt into a terminal to start work, and nothing enforced that the allocator had been consulted first, so two sessions could reach for the same issue and each believe it was theirs. This adds a request surface: a desired role, an issue or PR, and a stated intent, answered by an authorization decision and, on confirmation, an exclusive assignment from the allocator.
## Linked issue
Closes #643
## Surfaces
| Path | Method | Purpose |
|------|--------|---------|
| `/requests` | GET | Request form |
| `/requests` | POST | Render an intent preview. Never assigns. |
| `/api/v1/requests/preview` | POST | Intent preview as JSON |
| `/api/v1/requests/apply` | POST | Initiate, confirmed and audited, allocator-owned |
## Acceptance criteria
1. **Preview shows authorize/deny with reasons.** Five named checks, each with its own verdict, reason code, and detail: `authorization`, `capability`, `lease_availability`, `next_safe_action`, `head_pin`.
2. **Apply creates an exclusive assignment or returns wait/blocked.** Outcomes are `assigned_work` (201), `wait` (409), `blocked` (409), `denied` (403), `invalid_request` (400), `evidence_unavailable` (503).
3. **Duplicate assign rejected.** An active claim on the work unit, held by any session, blocks before an assignment is attempted.
4. **Tests for preview/apply/deny/collision.** 52 new tests across eight classes.
5. **UI never shows full secrets; brief user messaging.** Every interpolated value is escaped; the intent travels through the standard redaction pass before persistence.
## Design notes for the reviewer
**Apply runs the allocator twice, on purpose.** The allocator is the only source of exclusive ownership (#600/#613), and it selects work rather than taking orders. So `apply` runs a dry-run first and proceeds only when the allocator would independently pick the requested work unit; otherwise it returns `wait` and mutates nothing. The apply call carries the dry-run's `candidate_set_fingerprint` as a CAS pin (#776), and the result is re-checked on the way out so an assignment naming a different work unit is not read as success.
**The execution gate is action-scoped, not a phase bump.** `console_authz.ConsoleAction` gains an optional `execution_env_flag`, and `authorize` now computes `execution_enabled` via a new `execution_wired(action, env)` helper. Raising `ACTIVE_PHASE` would have enabled execution for every phase-2 action at once, including `system.restart_namespace` and the analytics ingest, whose execution paths are not implemented here. `initiate_workflow` is the only action declaring a flag (`WEBUI_REQUESTS_EXECUTION`); every other action keeps its previous behaviour and still reports `execution_enabled: false`.
**Operator-class authority.** `initiate_workflow` requires `operator` because its outcome is a claim, not a Gitea verdict. Requesting reviewer or merger work reserves that work; it grants no right to approve or merge, which stays with the MCP role profile.
**A denial is not a queue oracle.** An unauthorized principal never reaches the allocator or the control-plane DB at all.
## Fail-closed behaviour
An unreadable control-plane DB, an incomplete queue inventory (#758), an allocator that raises, an unpinned PR head, a PR head that moved, and an unconfirmed apply all deny without mutating. An unreadable claim inventory is never treated as "nothing holds this work unit".

Operators had to paste a role prompt into a terminal to start work, and
nothing enforced that the allocator had been consulted first, so two sessions
could reach for the same issue and each believe it was theirs. This adds a
request surface: a desired role, an issue or PR, and a stated intent, answered
by an authorization decision and - on confirmation - an exclusive assignment
from the allocator.
Preview (POST /api/v1/requests/preview, and the /requests form) runs five
checks and reports authorize/deny with a reason for each: console
authorization, capability resolution for the desired role, lease availability,
whether the allocator would independently select this work unit, and head
pinning for PR work. It is read-only - it calls the allocator with apply=false
and writes only an audit line. An unauthorized principal never reaches the
allocator or the control-plane DB, so a denial cannot enumerate the queue.
Initiation (POST /api/v1/requests/apply) never assigns the requested item
directly. It runs a dry-run first and proceeds only when the allocator would
independently pick that exact work unit, carrying the dry-run's
candidate_set_fingerprint as a CAS pin; otherwise it returns wait or blocked
and mutates nothing. An active claim on the work unit rejects a duplicate
assign before one is attempted. A returned assignment carries a handoff block
naming the required profile, namespace, and the actions that stay forbidden.
Authorization reuses the #633 model rather than adding a second one. The new
initiate_workflow action is operator-class because its outcome is a claim, not
a Gitea verdict: requesting reviewer or merger work reserves that work but
grants no right to approve or merge. Execution is gated by a new per-action
execution_env_flag (WEBUI_REQUESTS_EXECUTION), deliberately in place of raising
ACTIVE_PHASE - a phase bump would enable execution for every phase-2 action at
once, including ones whose execution path is not implemented. Actions that
declare no flag are unchanged and still report execution_enabled false.
Every preview and apply emits a console audit record correlated to the
resulting assignment by correlation.request_id.
Fail-closed throughout: an unreadable control-plane DB, an incomplete queue
inventory (#758), an allocator that raises, an unpinned PR head, a moved PR
head, and an unconfirmed apply all deny without mutating.

STATE: PR-open
WHO_IS_NEXT: author
NEXT_ACTION: Fix B1 by releasing or explicitly surfacing an assignment the allocator created when the egress selection does not match the request, and by handling the post-commit exception route; fix B2 by keeping the preview path free of session-row writes and reusing one session id across the dry-run and the apply. Add coverage for both, including a test that fails if an orphaned assignment is left behind.
NEXT_PROMPT:
Act as author on Scaled-Tech-Consulting/Gitea-Tools issue #643, PR #902, remote prgs. Read the reviewer REQUEST_CHANGES on PR #902 at head 433f66add864062df7c211d9b52fc74fcfccfb2f. Two code blockers must be resolved.
B1: in webui/request_service.py apply_request, when the allocator ran with apply=True and returned outcome assigned_work but _selection_matches fails against the requested work unit, the allocator has committed an assignment and lease via db.assign_and_lease; the current code returns mutation_performed false and leaves that lease orphaned. Release it or surface it with an explicit reclaim action, and report the mutation truthfully. The same state is reachable when _run_allocator's bare except Exception swallows an exception raised after the commit, since allocate_next_work only catches InvalidWorkKindError, LeaseRequiredError, and ControlPlaneError. Note that candidate_set_fingerprint hashes only kind and number, so the CAS pin cannot detect the lease-state change that causes the divergence.
B2: allocate_next_work calls db.upsert_session and db.expire_stale_leases unconditionally before the apply branch, so every preview writes a new webui-request-<hex> session row and mutates lease state while the payload reports dry_run true and mutation_performed false. Keep the preview path free of session-row writes and reuse a single session id across the dry-run and the apply so the created lease has a resolvable owner.
Tests: tests/test_webui_request_initiation.py test_allocator_drift_on_apply_is_not_read_as_an_assignment currently asserts the defective behaviour and must be changed to require the compensating release. Add coverage for default_allocator past its two fail-closed early returns and for default_claims_source, both of which have none.
Re-run WEBUI_TEST_OFFLINE=1 ../../venv/bin/python -m pytest tests/ -q from a branches/ worktree and compare against the clean-master baseline at 2f4dec83, which is 23 failed / 5190 passed / 6 skipped / 867 subtests. Then push to feat/issue-643-request-preview-initiate and request a fresh review.
WHAT_HAPPENED: Independent reviewer review of PR #902 at head 433f66ad. Full suite re-run on both the PR head and a clean-master baseline worktree under branches/; three single-guard mutation runs; authorization gate and rendering surface verified independently. Two code blockers found in the initiation path.
WHY: The apply path can leave an allocator-created assignment orphaned while reporting mutation_performed false, and the preview path writes control-plane session rows and expires leases while declaring itself read-only.

[THREAD STATE LEDGER] PR #902 — REQUEST_CHANGES posted to Gitea
What is true now:
PR state: open
Server-side decision state: REQUEST_CHANGES posted to Gitea
Local verdict/state: REQUEST_CHANGES prepared locally
Two code blockers, both in the initiation path. The authorization gate and the
rendering surface were checked independently and are clean; details below so the
re-review can skip them.
B1 — an allocator-created assignment can be orphaned and reported as no mutation
webui/request_service.py:745-781, with allocator_service.py:741-757, 1101-1142, 1339, 1460-1513.
Failure scenario, concrete:
WEBUI_REQUESTS_EXECUTION=1. An operator POSTs /api/v1/requests/apply
with {desired_role: author, work_kind: issue, work_number: 664, confirm: true}.
apply_request re-previews at line 720. The dry-run calls default_allocator(apply=False), which does a live load_queue_snapshot()
and gets candidates [issue#664, issue#665]; list_active_claims shows both
free; the allocator selects #664. Fingerprint fp = sha256([{issue,664},{issue,665}]).
In the window between that dry-run and the apply call at line 745, a
concurrent session takes a lease on #664. That window contains a second
full load_queue_snapshot() — a live Gitea fetch — so it is hundreds of
milliseconds to seconds wide, not microseconds. Foreign sessions acting on
this repo concurrently are an observed condition, not a hypothetical.
_run_allocator(apply=True) re-runs default_allocator. The queue is
unchanged, so cas_fp == fp and the #776 CAS pin passes. candidate_set_fingerprint (allocator_service.py:741-757) hashes only {kind, number} plus exclusions. Lease state is not an input to it, and
lease state is exactly what changed.
The selection loop (allocator_service.py:1101-1142) now skips #664 as SKIP_CLAIMED_BY_OTHER_SESSION and continues to select #665, then
calls db.assign_and_lease at line 1339. A durable assignment row and lease
on #665 are committed. It returns outcome=assigned_work, selected=#665.
Back in apply_request, _selection_matches(#665, request #664) is False,
so assigned is False and control reaches _refuse(...) at line 772, which
returns "mutation_performed": False and "assignment": None.
Wrong outcome: a real lease on #665 exists and is owned by a synthetic webui-request-<hex> session that no process heartbeats, resumes, or releases.
Nothing in this path releases it. #665 is unavailable to every other role
until the TTL expires, and the API response states that nothing changed, so
neither the operator nor any automation has a signal to reclaim it.
This is the direct answer to whether the CAS pin is sufficient: it is not, and
it cannot be made sufficient as written, because it is blind by construction to
the state transition that causes the divergence.
Second trigger, same class: the bare except Exception in _run_allocator
(line 864) returns None for any exception raised after db.assign_and_lease
has committed. allocate_next_work's own catch at allocator_service.py:1340
covers only InvalidWorkKindError, LeaseRequiredError, and ControlPlaneError, so an unexpected exception in the post-commit result
construction (for example a KeyError on selection[...] at lines 1425/1469,
or inside _next_command) is swallowed and surfaces as evidence_unavailable with mutation_performed: False — while the lease is
committed. So that bare except can indeed swallow a successful-but-partial result.
Coverage is inverted rather than absent. tests/test_webui_request_initiation.py:589-613
(test_allocator_drift_on_apply_is_not_read_as_an_assignment) constructs
exactly this state — the fake allocator returns assignment: {"assignment_id": "asn-wrong"} when apply=True — and then
asserts mutation_performed is False and assignment is None. The test
encodes the orphaned assignment as intended behaviour. No test asserts a
compensating release or any leak signal.
Fix direction: on an egress mismatch, release the assignment the allocator
created (or surface it explicitly with a reclaim action) and report mutation_performed truthfully. A lease-state-aware CAS token would narrow the
window but does not remove the need for the compensating path, since the
post-commit exception route reaches the same state.
B2 — the preview path writes to the control-plane DB, contradicting its stated contract
webui/request_service.py:556-582 and 892-934, with allocator_service.py:888-912.
Failure scenario, concrete:
An operator opens /requests and submits the preview form, or POSTs /api/v1/requests/preview. No confirmation, no execution flag needed —
preview only requires an authenticated operator-role principal.
allocate_next_work calls db.upsert_session(session_id=..., role=..., profile=..., pid=os.getpid()) at allocator_service.py:889-896 unconditionally, before the apply branch is ever consulted, then db.expire_stale_leases() at line 912.
default_allocator mints f"webui-request-{uuid.uuid4().hex[:12]}" fresh on
every call (line 920), so N previews write N session rows that are never
reused, never heartbeated, and never released.
Wrong outcome: the preview payload reports "dry_run": True and "mutation_performed": False (request_service.py:296-297), the module
docstring says "Read-only, always. It creates no assignment and never mutates",
and the form footer says "Preview is read-only and creates no assignment" —
while each preview appends a control-plane session row and mutates global lease
state through expire_stale_leases(). Row growth is unbounded and driven by an
ordinary operator refreshing a form. This feeds the known post-restart
reconcile degradation (accumulated dead-pid session rows), which currently has
no reaper, so the rows persist.
The same defect distorts ownership on the apply path: a single apply writes two session rows — one for the dry-run inside preview_request, one for the
apply call — and binds the resulting lease to the second. The assignment is
therefore owned by a session id that no process holds, which is also why B1's
orphan cannot be reclaimed by its owner.
Coverage is zero. default_allocator is exercised only at tests/test_webui_request_initiation.py:640-684, and both cases
(inventory_complete=False, fetch_error) return before reaching ControlPlaneDB() or allocate_next_work. default_claims_source has no test
at all. So upsert_session, the synthetic session id, and the CAS round-trip
are entirely untested.
Fix direction: do not write a session row on the preview path, and reuse one
session id across the dry-run and the apply so the created lease has a
resolvable owner.
Verified clean — no change requested
The execution gate did not loosen.ACTIVE_PHASE is still 1
(webui/console_authz.py:458). Every action in _ACTION_SPECS is phase 2 or 3;
there is no phase-1 action, so the action.phase <= ACTIVE_PHASE branch of execution_wired never fires for any registered action today. initiate_workflow
is the only action declaring execution_env_flag, so every other action takes
the if not flag: return False path, reports execution_enabled: false, and
denies under for_execution. Checked specifically: system.restart_namespace (phase 2, no flag) denies, and webui/sanctioned_restart.py additionally hardcodes execution_enabled: False
in its own payloads at lines 275/315/399 and calls authorize() without for_execution; /api/v1/analytics/usage gates on decision.allowed and decision.execution_enabled at webui/app.py:672 for record_analytics_usage (phase 2, no flag), so it stays dead.
One latent note, not a blocker: execution_enabled changed from a hardcoded False to wired, and webui/app.py:672 gates a real write on that field. No
phase-1 action exists today, but the moment one is added it would report execution_enabled: true without anyone touching the ingest route. Worth a
comment or an assertion that the registry holds no phase-1 action.
Rendering. Every interpolation in webui/request_views.py passes through _escape (html.escape(..., quote=True)), including the allocator evidence
JSON at lines 105-126 and both error fields at lines 131-141. Attributes are
single-quoted and quote=True escapes ' as well as ", so the attribute
contexts are safe. No injection path found. Minor doc inaccuracy only: the
module docstring says it "renders only values the service already produced
rather than echoing a raw request body back", but _form(submitted) does
re-echo submitted values — escaped, so the behaviour is correct and only the
comment overstates it.
The self-check on list_active_claims. It is redundant for safety and
load-bearing only for reporting. The allocator independently re-reads claims and
skips claimed candidates, so a duplicate would be refused either way; the
console's own _lease_check changes the reason code and the blocked-vs-wait
classification, not the outcome. It is not misleading, but it must not be read
as the duplicate-assignment guarantee — the atomic db.assign_and_lease is that
guarantee.
The fail-closed claims that hold. Unreadable DB → _load_claims returns None → _lease_check fails with evidence_unavailable, correct. Incomplete
inventory and fetch error → default_allocator returns None before touching
the DB, correct. Unpinned and moved head → _head_pin_check fails, correct.
Unconfirmed apply → refused at line 709 before the allocator runs, correct. The
allocator-exception claim is where it breaks down; see B1.
Mutation results
Each guard neutered one at a time in a throwaway worktree at the same head,
reverted after each run.
30 failed across 4 files, including test_execution_is_refused_while_phase_is_not_active, test_allowed_decision_never_reports_execution_enabled (7 subtests), test_analytics_ingest_unauthorized_denied, and test_preview_never_enables_execution
All three guards have real coverage. Guards with zero coverage: default_claims_source (no test), and everything in default_allocator past
the two fail-closed early returns — upsert_session, the synthetic session id,
and the CAS fingerprint round-trip. The _selection_matches guard has coverage
that fires, but as noted in B1 the assertion encodes the orphaned assignment
rather than catching it.
Validation, re-run by the reviewer
Both runs from branches/ worktrees, not /tmp, since several suites resolve
the repo root from the checkout path.
diff of the sorted FAILED lines from both runs is empty — the 23 signatures
are identical. The author's reported numbers reproduce exactly. The branch adds
52 passing tests and introduces no new failure signature. Scope matches the
stated file list; no unrelated files in the diff.

Full suite re-run on both the PR head and a clean-master baseline worktree under branches/; three single-guard mutation runs; authorization gate and rendering surface verified independently. Two code blockers found in the initiation path.
WHY: The apply path can leave an allocator-created assignment orphaned while reporting mutation_performed false, and the preview path writes control-plane session rows and expires leases while declaring itself read-only.

# Review — PR #902 (#643), head 433f66ad
Two code blockers, both in the initiation path. The authorization gate and the
rendering surface were checked independently and are clean; details below so the
re-review can skip them.
## B1 — an allocator-created assignment can be orphaned and reported as no mutation
`webui/request_service.py:745-781`, with `allocator_service.py:741-757`,
`1101-1142`, `1339`, `1460-1513`.
Failure scenario, concrete:
1. `WEBUI_REQUESTS_EXECUTION=1`. An operator POSTs `/api/v1/requests/apply`
with `{desired_role: author, work_kind: issue, work_number: 664, confirm: true}`.
2. `apply_request` re-previews at line 720. The dry-run calls
`default_allocator(apply=False)`, which does a live `load_queue_snapshot()`
and gets candidates `[issue#664, issue#665]`; `list_active_claims` shows both
free; the allocator selects `#664`. Fingerprint `fp = sha256([{issue,664},{issue,665}])`.
3. In the window between that dry-run and the apply call at line 745, a
concurrent session takes a lease on `#664`. That window contains a second
full `load_queue_snapshot()` — a live Gitea fetch — so it is hundreds of
milliseconds to seconds wide, not microseconds. Foreign sessions acting on
this repo concurrently are an observed condition, not a hypothetical.
4. `_run_allocator(apply=True)` re-runs `default_allocator`. The queue is
unchanged, so `cas_fp == fp` and the #776 CAS pin **passes**.
`candidate_set_fingerprint` (`allocator_service.py:741-757`) hashes only
`{kind, number}` plus exclusions. Lease state is not an input to it, and
lease state is exactly what changed.
5. The selection loop (`allocator_service.py:1101-1142`) now skips `#664` as
`SKIP_CLAIMED_BY_OTHER_SESSION` and `continue`s to select **`#665`**, then
calls `db.assign_and_lease` at line 1339. A durable assignment row and lease
on `#665` are committed. It returns `outcome=assigned_work`, `selected=#665`.
6. Back in `apply_request`, `_selection_matches(#665, request #664)` is False,
so `assigned` is False and control reaches `_refuse(...)` at line 772, which
returns `"mutation_performed": False` and `"assignment": None`.
Wrong outcome: a real lease on `#665` exists and is owned by a synthetic
`webui-request-<hex>` session that no process heartbeats, resumes, or releases.
Nothing in this path releases it. `#665` is unavailable to every other role
until the TTL expires, and the API response states that nothing changed, so
neither the operator nor any automation has a signal to reclaim it.
This is the direct answer to whether the CAS pin is sufficient: it is not, and
it cannot be made sufficient as written, because it is blind by construction to
the state transition that causes the divergence.
Second trigger, same class: the bare `except Exception` in `_run_allocator`
(line 864) returns `None` for any exception raised after `db.assign_and_lease`
has committed. `allocate_next_work`'s own catch at `allocator_service.py:1340`
covers only `InvalidWorkKindError`, `LeaseRequiredError`, and
`ControlPlaneError`, so an unexpected exception in the post-commit result
construction (for example a `KeyError` on `selection[...]` at lines 1425/1469,
or inside `_next_command`) is swallowed and surfaces as
`evidence_unavailable` with `mutation_performed: False` — while the lease is
committed. So that bare except can indeed swallow a successful-but-partial result.
Coverage is inverted rather than absent.
`tests/test_webui_request_initiation.py:589-613`
(`test_allocator_drift_on_apply_is_not_read_as_an_assignment`) constructs
exactly this state — the fake allocator returns
`assignment: {"assignment_id": "asn-wrong"}` when `apply=True` — and then
asserts `mutation_performed` is False and `assignment` is None. The test
encodes the orphaned assignment as intended behaviour. No test asserts a
compensating release or any leak signal.
Fix direction: on an egress mismatch, release the assignment the allocator
created (or surface it explicitly with a reclaim action) and report
`mutation_performed` truthfully. A lease-state-aware CAS token would narrow the
window but does not remove the need for the compensating path, since the
post-commit exception route reaches the same state.
## B2 — the preview path writes to the control-plane DB, contradicting its stated contract
`webui/request_service.py:556-582` and `892-934`, with
`allocator_service.py:888-912`.
Failure scenario, concrete:
1. An operator opens `/requests` and submits the preview form, or POSTs
`/api/v1/requests/preview`. No confirmation, no execution flag needed —
preview only requires an authenticated operator-role principal.
2. `preview_request` calls `_run_allocator(apply=False)` →
`default_allocator` → `allocate_next_work(..., apply=False)`.
3. `allocate_next_work` calls `db.upsert_session(session_id=..., role=...,
profile=..., pid=os.getpid())` at `allocator_service.py:889-896`
**unconditionally, before the apply branch is ever consulted**, then
`db.expire_stale_leases()` at line 912.
4. `default_allocator` mints `f"webui-request-{uuid.uuid4().hex[:12]}"` fresh on
every call (line 920), so N previews write N session rows that are never
reused, never heartbeated, and never released.
Wrong outcome: the preview payload reports `"dry_run": True` and
`"mutation_performed": False` (`request_service.py:296-297`), the module
docstring says "Read-only, always. It creates no assignment and never mutates",
and the form footer says "Preview is read-only and creates no assignment" —
while each preview appends a control-plane session row and mutates global lease
state through `expire_stale_leases()`. Row growth is unbounded and driven by an
ordinary operator refreshing a form. This feeds the known post-restart
reconcile degradation (accumulated dead-pid session rows), which currently has
no reaper, so the rows persist.
The same defect distorts ownership on the apply path: a single apply writes
**two** session rows — one for the dry-run inside `preview_request`, one for the
apply call — and binds the resulting lease to the second. The assignment is
therefore owned by a session id that no process holds, which is also why B1's
orphan cannot be reclaimed by its owner.
Coverage is zero. `default_allocator` is exercised only at
`tests/test_webui_request_initiation.py:640-684`, and both cases
(`inventory_complete=False`, `fetch_error`) return before reaching
`ControlPlaneDB()` or `allocate_next_work`. `default_claims_source` has no test
at all. So `upsert_session`, the synthetic session id, and the CAS round-trip
are entirely untested.
Fix direction: do not write a session row on the preview path, and reuse one
session id across the dry-run and the apply so the created lease has a
resolvable owner.
## Verified clean — no change requested
**The execution gate did not loosen.** `ACTIVE_PHASE` is still `1`
(`webui/console_authz.py:458`). Every action in `_ACTION_SPECS` is phase 2 or 3;
there is no phase-1 action, so the `action.phase <= ACTIVE_PHASE` branch of
`execution_wired` never fires for any registered action today. `initiate_workflow`
is the only action declaring `execution_env_flag`, so every other action takes
the `if not flag: return False` path, reports `execution_enabled: false`, and
denies under `for_execution`. Checked specifically:
`system.restart_namespace` (phase 2, no flag) denies, and
`webui/sanctioned_restart.py` additionally hardcodes `execution_enabled: False`
in its own payloads at lines 275/315/399 and calls `authorize()` without
`for_execution`; `/api/v1/analytics/usage` gates on
`decision.allowed and decision.execution_enabled` at `webui/app.py:672` for
`record_analytics_usage` (phase 2, no flag), so it stays dead.
One latent note, not a blocker: `execution_enabled` changed from a hardcoded
`False` to `wired`, and `webui/app.py:672` gates a real write on that field. No
phase-1 action exists today, but the moment one is added it would report
`execution_enabled: true` without anyone touching the ingest route. Worth a
comment or an assertion that the registry holds no phase-1 action.
**Rendering.** Every interpolation in `webui/request_views.py` passes through
`_escape` (`html.escape(..., quote=True)`), including the allocator evidence
JSON at lines 105-126 and both error fields at lines 131-141. Attributes are
single-quoted and `quote=True` escapes `'` as well as `"`, so the attribute
contexts are safe. No injection path found. Minor doc inaccuracy only: the
module docstring says it "renders only values the service already produced
rather than echoing a raw request body back", but `_form(submitted)` does
re-echo submitted values — escaped, so the behaviour is correct and only the
comment overstates it.
**The self-check on `list_active_claims`.** It is redundant for safety and
load-bearing only for reporting. The allocator independently re-reads claims and
skips claimed candidates, so a duplicate would be refused either way; the
console's own `_lease_check` changes the reason code and the `blocked`-vs-`wait`
classification, not the outcome. It is not misleading, but it must not be read
as the duplicate-assignment guarantee — the atomic `db.assign_and_lease` is that
guarantee.
**The fail-closed claims that hold.** Unreadable DB → `_load_claims` returns
`None` → `_lease_check` fails with `evidence_unavailable`, correct. Incomplete
inventory and fetch error → `default_allocator` returns `None` before touching
the DB, correct. Unpinned and moved head → `_head_pin_check` fails, correct.
Unconfirmed apply → refused at line 709 before the allocator runs, correct. The
allocator-exception claim is where it breaks down; see B1.
## Mutation results
Each guard neutered one at a time in a throwaway worktree at the same head,
reverted after each run.
| Guard | Mutation | Result |
|---|---|---|
| Duplicate-assignment check | `_lease_check`: `if claim:` → `if False:` | **1 failed**, 51 passed — `TestApplyOutcomes::test_duplicate_assignment_rejected` |
| `_selection_matches` egress guard | dropped the `and _selection_matches(...)` term from `assigned` | **1 failed**, 51 passed — `TestApplyOutcomes::test_allocator_drift_on_apply_is_not_read_as_an_assignment` |
| `execution_wired` flag | unflagged actions return `True` instead of `False` | **30 failed** across 4 files, including `test_execution_is_refused_while_phase_is_not_active`, `test_allowed_decision_never_reports_execution_enabled` (7 subtests), `test_analytics_ingest_unauthorized_denied`, and `test_preview_never_enables_execution` |
All three guards have real coverage. Guards with **zero** coverage:
`default_claims_source` (no test), and everything in `default_allocator` past
the two fail-closed early returns — `upsert_session`, the synthetic session id,
and the CAS fingerprint round-trip. The `_selection_matches` guard has coverage
that fires, but as noted in B1 the assertion encodes the orphaned assignment
rather than catching it.
## Validation, re-run by the reviewer
Both runs from `branches/` worktrees, not `/tmp`, since several suites resolve
the repo root from the checkout path.

```
Addresses both blockers from the PR #902 review (review 589) for issue #643.
B1 — an allocator-created assignment could be orphaned and reported as no
mutation.
apply_request re-previews, then re-runs the allocator with apply=True. The CAS
fingerprint hashes only {kind, number} plus exclusions, so a competing lease
taken on the requested unit inside the window leaves the fingerprint identical:
the pin passes, the selection loop skips the now-claimed unit and commits an
assignment on the *next* one, and _selection_matches then fails on egress. The
old code returned mutation_performed False with that lease still committed and
owned by a synthetic session nothing heartbeats. The window contains a second
full load_queue_snapshot(), so it is seconds wide, and foreign sessions acting
on this repo concurrently are an observed condition.
The egress mismatch now releases the assignment the allocator created before
refusing. When the release succeeds the refusal reports mutation_performed
False and a compensation record; when it fails the response carries
mutation_performed True, an explicit orphaned_assignment, and a
gitea_release_workflow_lease reclaim action, because claiming nothing changed
while a lease is live is the defect rather than a report of it.
The same state was reachable through _run_allocator's bare except Exception:
allocate_next_work only catches InvalidWorkKindError, LeaseRequiredError and
ControlPlaneError, so anything raised after assign_and_lease committed arrived
as "no result" with a durable lease. A None result on the apply path now sweeps
and releases whatever this flow's session owns. That sweep is only possible
because of the B2 fix below — the session id is now stable across the flow, so
the lease is findable.
B2 — the "read-only" preview wrote to the control-plane DB.
allocate_next_work called db.upsert_session and db.expire_stale_leases
unconditionally, before the apply branch was consulted, and default_allocator
minted a fresh webui-request-<hex> per call. Every preview therefore appended a
never-reused session row and mutated global lease state while the payload said
dry_run True / mutation_performed False, driven by an operator refreshing a
form. One apply wrote two rows and bound the lease to the second, which is why
B1's orphan had no reclaimable owner.
allocate_next_work gains a keyword-only side_effect_free flag, default False so
every existing caller is byte-for-byte unchanged. Under the flag both writes are
suppressed and expired leases are instead filtered out of the claim map in
memory, which reaches the same selection the sweep would have produced without
persisting anything; a claim whose expiry cannot be parsed is kept, since an
unreadable expiry is not evidence that work is free. side_effect_free with
apply=True fails closed rather than silently reserving. request_service mints
one session id per request flow and threads it through both the dry-run and the
apply, and the dry-run now routes through the side-effect-free path.
Coverage.
test_allocator_drift_on_apply_is_not_read_as_an_assignment asserted the defect —
it built the orphan state and then required mutation_performed to be False, which
a leak satisfies. It now requires the compensating release. Added: release-failure
surfacing a reclaim action, an assignment with no lease id, the post-commit
exception route, and session-id identity across the flow. The two areas the review
named as having zero coverage now have it: default_allocator past its two
fail-closed early returns (side_effect_free routing, session-id pass-through and
minting, scope and fingerprint propagation) and default_claims_source (scoped
read, and an unreadable substrate denying rather than reading as "nothing
claimed"). allocator_service gains side-effect-free tests against a real
temp-file DB plus the expiry-filter unit tests.
Every new guard was mutation-tested by reverting it one at a time: B1
compensation removed → 3 failures; post-commit sweep removed → 1; session id
re-minted per call → 2; side_effect_free ignored → 3; in-memory expiry filter
removed → 1.
Verification: WEBUI_TEST_OFFLINE=1 python -m pytest tests/ -q from this
branches/ worktree gives 23 failed, 5263 passed, 6 skipped, 899 subtests. The
sorted FAILED set is identical to the reviewer's clean-master baseline at
2f4dec83 (23 failed, 5190 passed) — no new, changed, or disappeared failure —
and 21 tests were added over the reviewed head's 5242. Zero conflict markers;
py_compile passes; git diff --check clean.

The fix landed as 53ce1b1 (fast-forward, non-force, no rebase); master 8598537a was then integrated by update-by-merge, since PR #886 landed while this work was in progress and branch protection requires a current base.
B1 — the apply path no longer leaves an assignment behind
The egress mismatch now releases what the allocator committed:
When the release succeeds the refusal reports mutation_performed: false plus a compensation record; when it fails the response carries mutation_performed: true, an explicit orphaned_assignment, and a gitea_release_workflow_lease reclaim action naming the lease and its owning session. Reporting "nothing changed" while a lease is live was the defect, so the truthful signal is now part of the contract rather than an afterthought.
The post-commit exception route reaches the same state and is handled too. allocate_next_work catches only InvalidWorkKindError, LeaseRequiredError and ControlPlaneError, so anything else raised after assign_and_lease committed arrives at _run_allocator as None with a durable lease. A None result on the apply path now sweeps and releases whatever this flow's session owns. That sweep is only possible because of B2: the session id is stable across the flow, so the lease is findable.
The CAS fingerprint itself is unchanged. As the review noted, it is blind by construction to the lease-state transition that causes the divergence, so narrowing the window would not remove the need for the compensating path.
B2 — the preview no longer writes to the control-plane DB
allocate_next_work gains a keyword-only side_effect_free flag, defaulting to False so every existing caller — the MCP tool and all 13 test modules — is unchanged. Under the flag upsert_session and expire_stale_leases are both suppressed, and expired leases are instead filtered out of the claim map in memory by _drop_expired_claims, which reaches the same selection the sweep would have produced without persisting anything. A claim whose expires_at cannot be parsed is kept: an unreadable expiry is not evidence that work is free. side_effect_free together with apply=True fails closed rather than silently reserving.
request_service now mints one session id per request flow via _new_session_id() and threads it through both the dry-run and the apply, and default_allocator routes a dry run through the side-effect-free path. An apply therefore writes one session row instead of two, and the lease it creates is owned by an id the request flow still holds.
Coverage
test_allocator_drift_on_apply_is_not_read_as_an_assignment asserted the defect — it built the orphan state and then required mutation_performed to be False, which a leak satisfies just as well. It now requires the compensating release and asserts the released lease id.
Added for B1: release-failure surfacing the reclaim action, an assignment carrying no lease id, the post-commit exception route, and session-id identity across the flow. Added for the two areas the review identified as having zero coverage: default_allocator past both fail-closed early returns (side-effect-free routing, session-id pass-through and minting, scope and fingerprint propagation) and default_claims_source (scoped read, plus an unreadable substrate denying rather than reading as "nothing claimed"). tests/test_allocator_service.py gains side-effect-free tests against a real temp-file control-plane DB, plus unit tests for the expiry filter.
Every new guard was mutation-tested by reverting it one at a time in the worktree and restoring after each run:
Guard neutered

B1 compensation branch removed

post-commit sweep removed
1
session id re-minted per call

Validation
Both runs from branches/ worktrees, never /tmp. The baseline was re-measured at the new master, since the review's 2f4dec83 baseline predates PR #886 landing.
The sorted FAILED diff between the two is empty — 23 identical signatures, no new failure, none changed, none disappeared. The 23 are pre-existing on clean master and are disclosed rather than concealed; none is touched by this change. The branch adds 73 passing tests over that baseline: 52 from the original #643 work plus 21 from this remediation. Targeted suites tests/test_webui_request_initiation.py and tests/test_allocator_service.py: 88 passed, 26 subtests.
Also verified: zero conflict markers; py_compile passes on all four changed files; git diff --check clean; Closes #643 remains in the PR body; scope is four files staged explicitly with no unrelated change; and mergeable_after: false from update-by-merge was stale cache — git merge-base --is-ancestor 8598537a HEAD exits 0, and live state now reports mergeable: true, has_conflicts: false, commits_behind: 0.

what is true now:
Server-side decision state: PR #902 is in open state at head 6da68fffb889a0e99e6fd648046f2a2e3c54fc77, base master @ 8598537a3547b646bfeedf6f96482959489746dd. Gitea reports mergeable: true, has_conflicts: false, commits_behind: 0, approval_at_current_head: false. The only review verdict on this PR is the REQUEST_CHANGES recorded at the former head 433f66ad.
Local verdict/state: both blockers from review 589 are implemented and verified in the bound worktree; full suite 23 failed / 5303 passed against a clean-master baseline of 23 failed / 5230 passed, with an identical failure set.
what changed:
B1: an allocator-committed assignment that fails the egress selection check is released, with compensation, or surfaced as orphaned_assignment with a reclaim action when the release fails; the post-commit exception route sweeps the flow's session leases.
B2: allocate_next_work gained side_effect_free (default False); the preview path writes no session row and sweeps no leases; one session id spans the dry-run and the apply.
Tests: the inverted drift test now requires the release; coverage added for default_allocator past its early returns and for default_claims_source; five guards mutation-tested.
Required action: perform a fresh independent review of PR #902 at exact head 6da68fffb889a0e99e6fd648046f2a2e3c54fc77 and record a verdict at that exact head.
Do not do: do not reuse review 589 recorded at 433f66ad; do not treat the former drift test as evidence about the egress guard, since it previously asserted the defect; do not rebase or force-push this branch; do not merge from the author role.

WHAT_HAPPENED: An author session implemented both blockers from reviewer review 589 — the compensating release for an allocator-created assignment that fails the egress check, and a genuinely side-effect-free preview path — added regression coverage for each including the two zero-coverage areas the review named, corrected the drift test that asserted the defect, published the fix, and integrated master after PR #886 landed.

## Author remediation of review 589 — both blockers addressed
Reviewed head `433f66add864062df7c211d9b52fc74fcfccfb2f` → new head `6da68fffb889a0e99e6fd648046f2a2e3c54fc77`. The fix landed as `53ce1b1` (fast-forward, non-force, no rebase); master `8598537a` was then integrated by update-by-merge, since PR #886 landed while this work was in progress and branch protection requires a current base.
### B1 — the apply path no longer leaves an assignment behind
The egress mismatch now releases what the allocator committed:
```python
committed = bool(outcome == allocator_service.OUTCOME_ASSIGNED and assignment)
assigned = bool(committed and _selection_matches(allocation.get("selected"), request))
if not assigned:
if committed:
compensation = _release_stray_assignment(request, allocation,
session_id=session_id)
```
When the release succeeds the refusal reports `mutation_performed: false` plus a `compensation` record; when it fails the response carries `mutation_performed: true`, an explicit `orphaned_assignment`, and a `gitea_release_workflow_lease` reclaim action naming the lease and its owning session. Reporting "nothing changed" while a lease is live was the defect, so the truthful signal is now part of the contract rather than an afterthought.
The post-commit exception route reaches the same state and is handled too. `allocate_next_work` catches only `InvalidWorkKindError`, `LeaseRequiredError` and `ControlPlaneError`, so anything else raised after `assign_and_lease` committed arrives at `_run_allocator` as `None` with a durable lease. A `None` result on the apply path now sweeps and releases whatever this flow's session owns. That sweep is only possible because of B2: the session id is stable across the flow, so the lease is findable.
The CAS fingerprint itself is unchanged. As the review noted, it is blind by construction to the lease-state transition that causes the divergence, so narrowing the window would not remove the need for the compensating path.
### B2 — the preview no longer writes to the control-plane DB
`allocate_next_work` gains a keyword-only `side_effect_free` flag, defaulting to `False` so every existing caller — the MCP tool and all 13 test modules — is unchanged. Under the flag `upsert_session` and `expire_stale_leases` are both suppressed, and expired leases are instead filtered out of the claim map in memory by `_drop_expired_claims`, which reaches the same selection the sweep would have produced without persisting anything. A claim whose `expires_at` cannot be parsed is **kept**: an unreadable expiry is not evidence that work is free. `side_effect_free` together with `apply=True` fails closed rather than silently reserving.
`request_service` now mints one session id per request flow via `_new_session_id()` and threads it through both the dry-run and the apply, and `default_allocator` routes a dry run through the side-effect-free path. An apply therefore writes one session row instead of two, and the lease it creates is owned by an id the request flow still holds.
### Coverage
`test_allocator_drift_on_apply_is_not_read_as_an_assignment` asserted the defect — it built the orphan state and then required `mutation_performed` to be `False`, which a leak satisfies just as well. It now requires the compensating release and asserts the released lease id.
Added for B1: release-failure surfacing the reclaim action, an assignment carrying no lease id, the post-commit exception route, and session-id identity across the flow. Added for the two areas the review identified as having zero coverage: `default_allocator` past both fail-closed early returns (side-effect-free routing, session-id pass-through and minting, scope and fingerprint propagation) and `default_claims_source` (scoped read, plus an unreadable substrate denying rather than reading as "nothing claimed"). `tests/test_allocator_service.py` gains side-effect-free tests against a real temp-file control-plane DB, plus unit tests for the expiry filter.
Every new guard was mutation-tested by reverting it one at a time in the worktree and restoring after each run:
| Guard neutered | Failures |
|---|---|
| B1 compensation branch removed | 3 |
| post-commit sweep removed | 1 |
| session id re-minted per call | 2 |
| `side_effect_free` ignored | 3 |
| in-memory expiry filter removed | 1 |
### Validation
Both runs from `branches/` worktrees, never `/tmp`. The baseline was re-measured at the **new** master, since the review's `2f4dec83` baseline predates PR #886 landing.

NEXT_ACTION: Route the claim map the console reads through the same expiry filter the allocator now applies, so a lease whose expires_at has passed while its row still reads status 'active' no longer denies preview and apply. Keep the rule that an unparseable expires_at is retained. Add coverage for an expired-but-unswept lease, and give the _claimed fixture a future expires_at so the duplicate-assignment tests prove what their names say.
NEXT_PROMPT:
Act as author on Scaled-Tech-Consulting/Gitea-Tools issue #643, PR #902, remote prgs. Read the reviewer REQUEST_CHANGES on PR #902 at head d0006e9f714b8754beead64e15d03f769e872543. B1 and B2 from review 589 are fixed and were independently mutation-tested; one new blocker (B3) was introduced by the B2 fix and must be resolved.
B3: preview_request no longer triggers a lease sweep, which is the correct half of the B2 fix. But webui/request_service.py default_claims_source still calls db.list_active_claims, and that query filters on l.status = 'active' alone and never compares expires_at. Before the B2 fix, allocate_next_work's unconditional db.expire_stale_leases() ran inside the preview and flipped expired rows to 'expired' before _load_claims read them, so _lease_check saw a clean view. Nothing on the console path sweeps now, so a lease whose TTL has passed while its row still reads 'active' makes _lease_check fail with duplicate_assignment: preview reports blocked, and apply_request refuses 409 at the preview gate before the allocator is consulted. On the same DB, allocate_next_work(side_effect_free=True) drops that identical claim through _drop_expired_claims and would select the unit. Letting a lease lapse by TTL without an explicit release is the normal end state in this control plane, so this denies the feature's primary path for work units that are in fact unheld.
Fix: apply the same in-memory expiry filter to the claim map the console reads — in _load_claims or default_claims_source — preserving the rule that a claim with an unparseable expires_at is kept. Then make the two views agree by construction rather than by coincidence.
Coverage: add a test with a control-plane lease row whose expires_at is in the past and whose status is still 'active', asserting that preview authorizes and that apply reaches the allocator. tests/test_webui_request_initiation.py _claimed() hard-codes expires_at 2026-07-25T09:10:37Z, a timestamp already in the past, so every duplicate-assignment test currently asserts that an expired claim blocks; move it to a future expiry so the duplicate guard is tested against a live claim.
Re-run WEBUI_TEST_OFFLINE=1 ../../venv/bin/python -m pytest tests/ -q from a branches/ worktree and compare against master 715863799f7b, which gives 23 failed / 5256 passed / 6 skipped / 914 subtests. Then push to feat/issue-643-request-preview-initiate and request a fresh review.
WHAT_HAPPENED: Independent reviewer review of PR #902 at head d0006e9f. The head moved twice during the session (433f66ad to 6da68fff to d0006e9f); both later commits are master merges, and the effective diff against master 715863799f is content-identical across them — only blob ids and hunk offsets in webui/app.py and webui/nav.py shifted. Full suite re-run at the reviewed head and at a clean master baseline worktree, both under branches/. Four single-guard mutation runs against the new B1/B2 guards. One new blocker found, introduced by the B2 fix.
WHY: The B2 fix removed the lease sweep from the preview path but left the console's own claim query filtering on lease status alone, so a lease past its TTL that no sweep has touched denies preview and apply for a work unit the allocator itself treats as unheld.

[THREAD STATE LEDGER] PR #902 — REQUEST_CHANGES posted to Gitea
What is true now:
PR state: open
Server-side decision state: REQUEST_CHANGES posted to Gitea
Local verdict/state: REQUEST_CHANGES prepared locally at head d0006e9f
Both prior blockers are genuinely fixed, and I confirmed each new guard by
reverting it and watching a test fail. The B2 fix, however, removed a write that
another code path was silently depending on, and that dependency is not covered.
One blocker, then the verification detail so the re-review can skip it.
B1 (review 589) — fixed
webui/request_service.py:783-861, _release_stray_assignment at :960-1035, _sweep_session_leases at :1063-1105.
The egress mismatch now releases the assignment the allocator committed before
refusing. I traced the release end to end rather than trusting the shape: allocation["assignment"] is AssignmentResult.as_dict(), which carries lease_id (control_plane_db.py:333,352); owner resolves from allocation["session_id"], which allocate_next_work sets to the id the caller
passed (allocator_service.py:1449); release_lease requires row["session_id"] == session_id and raises ForeignLeaseError otherwise
(control_plane_db.py:1805), so the ownership match is real rather than assumed. release_lease_recorded also flips the assignments row to released and
writes a lease_released event (:1819-1858), so the compensation is complete
and auditable, not lease-only.
The wait and no_safe_work outcomes also return a populated assignment
dict, and committed correctly gates on outcome == OUTCOME_ASSIGNED, so a
foreign lease surfaced under wait is never released. That distinction matters
and it is right.
The release-failure branch reports mutation_performed: True with an explicit orphaned_assignment and a gitea_release_workflow_lease reclaim action. That
is the correct direction: a live lease reported as "nothing changed" was the
defect.
The post-commit exception route is handled by _sweep_session_leases, which is
only sound because the session id is now stable across the flow — the two fixes
depend on each other, and the commit message says so.
Mutation-tested: removing the release body gives 2 failures
(test_allocator_drift_on_apply_is_not_read_as_an_assignment, test_drift_whose_release_fails_reports_the_orphan_and_a_reclaim); stubbing out
the post-commit sweep gives 1
(test_exception_after_commit_releases_the_session_lease). The drift test no
longer encodes the defect — it now asserts released == ["lease-wrong"] and compensation["released"].
B2 (review 589) — fixed, and this is where B3 comes from
allocator_service.py:867-990, _drop_expired_claims at :764-782, webui/request_service.py:1172 (side_effect_free=not apply).
allocate_next_work gains a keyword-only side_effect_free, default False,
so every existing caller is unchanged; under the flag upsert_session and expire_stale_leases are both suppressed, and side_effect_free with apply=True fails closed instead of quietly reserving. The session id is minted
once per request flow and threaded through both halves. Keeping a claim whose expires_at cannot be parsed is the right call — an unreadable expiry is not
evidence that work is free.
Mutation-tested: ignoring the suppression gives 3 failures in SideEffectFreeAllocationTest; re-minting the session id per call gives 1
(test_caller_session_id_is_passed_through_verbatim).
B3 — an expired-but-unswept lease now denies work the allocator considers unheld
webui/request_service.py:1118-1127 (default_claims_source) and :412-454
(_lease_check), against allocator_service.py:764-782.
The suppressed expire_stale_leases() was doing double duty. In preview_request the allocator runs before_load_claims
(request_service.py:592-599), so at 433f66ad the sweep flipped every
past-TTL lease to expired and the claim query that followed saw a clean view.
The fix compensated for the missing sweep inside the allocator, via _drop_expired_claims, but the console reads claims through its own path: default_claims_source calls db.list_active_claims, which filters on l.status = 'active' alone (control_plane_db.py:1616-1661, 1694-1697) and
never compares expires_at. Only expire_stale_leases and require_valid_assignment flip those rows, and neither is on this path.
Failure scenario, concrete:
An author session takes a lease on issue #664 and dies without releasing it —
the standard end state here; "let the TTL expire" is the routine advice.
Ten minutes later its expires_at has passed, but the row still reads status = 'active' because nothing has swept.
An operator opens /requests, asks for author on issue #664, and submits.
_run_allocator(apply=False) runs side_effect_free, drops that claim in
memory, and selects #664 — the allocator's own view is that #664 is unheld.
_load_claims then calls list_active_claims, which still returns the
lapsed lease. _lease_check fails with duplicate_assignment.
authorized is False, so the preview reports blocked and cites an
"active author lease" that expired ten minutes ago. apply_request refuses
409 at :756-771, before the allocator is ever consulted on the apply.
Wrong outcome: the console cannot initiate work on any unit carrying a lapsed
lease, and it reports contradictory evidence — next_safe_action passes because
the allocator selected the unit, while lease_availability fails claiming the
unit is held. Nothing in the console path clears the row, so the refusal is not
transient: it persists until some unrelated non-side-effect-free allocator call
happens to sweep. This is a regression against 433f66ad, where the preview's own
sweep cleared the row and the request proceeded.
Reproduced at this head against a real temp-file control-plane DB — one lease, expires_at 30 minutes in the past, status left active:
lease status='active' expires_at='2026-07-25T11:19:19Z' (in the past)
list_active_claims -> [('issue', 664)] # what _lease_check reads
_lease_check.ok=False reason=duplicate_assignment
_drop_expired_claims -> [] # what the allocator selects over
DIVERGENCE
And the sweep that used to run on the preview path is exactly what closed the
gap:
before sweep, claims = [('issue', 664)]
after sweep, claims = []
Coverage is zero, and the fixture actively hides it: tests/test_webui_request_initiation.py:199-209_claimed() hard-codes expires_at2026-07-25T09:10:37Z — a timestamp in the past. Every
duplicate-assignment assertion in the suite therefore proves that an expired
claim blocks, which is the behaviour at issue, and no test constructs a lapsed
row and asserts the request proceeds.
Fix direction: filter the console's claim map through the same expiry rule the
allocator now uses, in _load_claims or default_claims_source, keeping the
unparseable-expiry-is-kept rule. Then the two views agree by construction. Give _claimed() a future expiry so the duplicate guard is tested against a live
claim, and add a case with a past expires_at and status = 'active' asserting
the preview authorizes.

Act as author on Scaled-Tech-Consulting/Gitea-Tools issue #643, PR #902, remote prgs. Read the reviewer REQUEST_CHANGES on PR #902 at head d0006e9f714b8754beead64e15d03f769e872543. B1 and B2 from review 589 are fixed and were independently mutation-tested; one new blocker (B3) was introduced by the B2 fix and must be resolved.
B3: preview_request no longer triggers a lease sweep, which is the correct half of the B2 fix. But webui/request_service.py default_claims_source still calls db.list_active_claims, and that query filters on l.status = 'active' alone and never compares expires_at. Before the B2 fix, allocate_next_work's unconditional db.expire_stale_leases() ran inside the preview and flipped expired rows to 'expired' before _load_claims read them, so _lease_check saw a clean view. Nothing on the console path sweeps now, so a lease whose TTL has passed while its row still reads 'active' makes _lease_check fail with duplicate_assignment: preview reports blocked, and apply_request refuses 409 at the preview gate before the allocator is consulted. On the same DB, allocate_next_work(side_effect_free=True) drops that identical claim through _drop_expired_claims and would select the unit. Letting a lease lapse by TTL without an explicit release is the normal end state in this control plane, so this denies the feature's primary path for work units that are in fact unheld.
Fix: apply the same in-memory expiry filter to the claim map the console reads — in _load_claims or default_claims_source — preserving the rule that a claim with an unparseable expires_at is kept. Then make the two views agree by construction rather than by coincidence.
Coverage: add a test with a control-plane lease row whose expires_at is in the past and whose status is still 'active', asserting that preview authorizes and that apply reaches the allocator. tests/test_webui_request_initiation.py _claimed() hard-codes expires_at 2026-07-25T09:10:37Z, a timestamp already in the past, so every duplicate-assignment test currently asserts that an expired claim blocks; move it to a future expiry so the duplicate guard is tested against a live claim.

WHAT_HAPPENED: Independent reviewer review of PR #902 at head d0006e9f. The head moved twice during the session (433f66ad to 6da68fff to d0006e9f); both later commits are master merges, and the effective diff against master 715863799f is content-identical across them — only blob ids and hunk offsets in webui/app.py and webui/nav.py shifted. Full suite re-run at the reviewed head and at a clean master baseline worktree, both under branches/. Four single-guard mutation runs against the new B1/B2 guards. One new blocker found, introduced by the B2 fix.
WHY: The B2 fix removed the lease sweep from the preview path but left the console's own claim query filtering on lease status alone, so a lease past its TTL that no sweep has touched denies preview and apply for a work unit the allocator itself treats as unheld.

# Review — PR #902 (#643), head d0006e9f
Both prior blockers are genuinely fixed, and I confirmed each new guard by
reverting it and watching a test fail. The B2 fix, however, removed a write that
another code path was silently depending on, and that dependency is not covered.
One blocker, then the verification detail so the re-review can skip it.
## B1 (review 589) — fixed
`webui/request_service.py:783-861`, `_release_stray_assignment` at `:960-1035`,
`_sweep_session_leases` at `:1063-1105`.
The egress mismatch now releases the assignment the allocator committed before
refusing. I traced the release end to end rather than trusting the shape:
`allocation["assignment"]` is `AssignmentResult.as_dict()`, which carries
`lease_id` (`control_plane_db.py:333,352`); `owner` resolves from
`allocation["session_id"]`, which `allocate_next_work` sets to the id the caller
passed (`allocator_service.py:1449`); `release_lease` requires
`row["session_id"] == session_id` and raises `ForeignLeaseError` otherwise
(`control_plane_db.py:1805`), so the ownership match is real rather than assumed.
`release_lease_recorded` also flips the `assignments` row to `released` and
writes a `lease_released` event (`:1819-1858`), so the compensation is complete
and auditable, not lease-only.
The `wait` and `no_safe_work` outcomes also return a populated `assignment`
dict, and `committed` correctly gates on `outcome == OUTCOME_ASSIGNED`, so a
foreign lease surfaced under `wait` is never released. That distinction matters
and it is right.
The release-failure branch reports `mutation_performed: True` with an explicit
`orphaned_assignment` and a `gitea_release_workflow_lease` reclaim action. That
is the correct direction: a live lease reported as "nothing changed" was the
defect.
The post-commit exception route is handled by `_sweep_session_leases`, which is
only sound because the session id is now stable across the flow — the two fixes
depend on each other, and the commit message says so.
Mutation-tested: removing the release body gives **2 failures**
(`test_allocator_drift_on_apply_is_not_read_as_an_assignment`,
`test_drift_whose_release_fails_reports_the_orphan_and_a_reclaim`); stubbing out
the post-commit sweep gives **1**
(`test_exception_after_commit_releases_the_session_lease`). The drift test no
longer encodes the defect — it now asserts `released == ["lease-wrong"]` and
`compensation["released"]`.
## B2 (review 589) — fixed, and this is where B3 comes from
`allocator_service.py:867-990`, `_drop_expired_claims` at `:764-782`,
`webui/request_service.py:1172` (`side_effect_free=not apply`).
`allocate_next_work` gains a keyword-only `side_effect_free`, default `False`,
so every existing caller is unchanged; under the flag `upsert_session` and
`expire_stale_leases` are both suppressed, and `side_effect_free` with
`apply=True` fails closed instead of quietly reserving. The session id is minted
once per request flow and threaded through both halves. Keeping a claim whose
`expires_at` cannot be parsed is the right call — an unreadable expiry is not
evidence that work is free.
Mutation-tested: ignoring the suppression gives **3 failures** in
`SideEffectFreeAllocationTest`; re-minting the session id per call gives **1**
(`test_caller_session_id_is_passed_through_verbatim`).
## B3 — an expired-but-unswept lease now denies work the allocator considers unheld
`webui/request_service.py:1118-1127` (`default_claims_source`) and `:412-454`
(`_lease_check`), against `allocator_service.py:764-782`.
The suppressed `expire_stale_leases()` was doing double duty. In
`preview_request` the allocator runs **before** `_load_claims`
(`request_service.py:592-599`), so at 433f66ad the sweep flipped every
past-TTL lease to `expired` and the claim query that followed saw a clean view.
The fix compensated for the missing sweep **inside** the allocator, via
`_drop_expired_claims`, but the console reads claims through its own path:
`default_claims_source` calls `db.list_active_claims`, which filters on
`l.status = 'active'` alone (`control_plane_db.py:1616-1661`, `1694-1697`) and
never compares `expires_at`. Only `expire_stale_leases` and
`require_valid_assignment` flip those rows, and neither is on this path.
Failure scenario, concrete:
1. An author session takes a lease on issue #664 and dies without releasing it —
the standard end state here; "let the TTL expire" is the routine advice.
2. Ten minutes later its `expires_at` has passed, but the row still reads
`status = 'active'` because nothing has swept.
3. An operator opens `/requests`, asks for author on issue #664, and submits.
4. `_run_allocator(apply=False)` runs `side_effect_free`, drops that claim in
memory, and selects #664 — the allocator's own view is that #664 is unheld.
5. `_load_claims` then calls `list_active_claims`, which still returns the
lapsed lease. `_lease_check` fails with `duplicate_assignment`.
6. `authorized` is False, so the preview reports `blocked` and cites an
"active author lease" that expired ten minutes ago. `apply_request` refuses
409 at `:756-771`, before the allocator is ever consulted on the apply.
Wrong outcome: the console cannot initiate work on any unit carrying a lapsed
lease, and it reports contradictory evidence — `next_safe_action` passes because
the allocator selected the unit, while `lease_availability` fails claiming the
unit is held. Nothing in the console path clears the row, so the refusal is not
transient: it persists until some unrelated non-side-effect-free allocator call
happens to sweep. This is a regression against 433f66ad, where the preview's own
sweep cleared the row and the request proceeded.
Reproduced at this head against a real temp-file control-plane DB — one lease,
`expires_at` 30 minutes in the past, status left `active`:
```text
lease status='active' expires_at='2026-07-25T11:19:19Z' (in the past)
list_active_claims -> [('issue', 664)] # what _lease_check reads
_lease_check.ok=False reason=duplicate_assignment
_drop_expired_claims -> [] # what the allocator selects over
DIVERGENCE
```
And the sweep that used to run on the preview path is exactly what closed the
gap:
```text
before sweep, claims = [('issue', 664)]
after sweep, claims = []
```
Coverage is zero, and the fixture actively hides it:
`tests/test_webui_request_initiation.py:199-209` `_claimed()` hard-codes
`expires_at` `2026-07-25T09:10:37Z` — a timestamp in the past. Every
duplicate-assignment assertion in the suite therefore proves that an *expired*
claim blocks, which is the behaviour at issue, and no test constructs a lapsed
row and asserts the request proceeds.
Fix direction: filter the console's claim map through the same expiry rule the
allocator now uses, in `_load_claims` or `default_claims_source`, keeping the
unparseable-expiry-is-kept rule. Then the two views agree by construction. Give
`_claimed()` a future expiry so the duplicate guard is tested against a live
claim, and add a case with a past `expires_at` and `status = 'active'` asserting
the preview authorizes.
## Verified clean — no change requested
**Scope.** The effective diff against master is 11 files, exactly the stated
list. The two commits added since the reviewed 433f66ad are master merges only:
`git diff master...HEAD` at 6da68fff and at d0006e9f differ only in blob ids and
hunk offsets for `webui/app.py` and `webui/nav.py`; every added and removed line
is identical, so the merge resolution introduced nothing. The restart-class files
that appear in a two-dot diff come from #886 landing on master, not from this
branch.
**The compensation cannot release someone else's lease.** Covered under B1
above: `committed` gates on `OUTCOME_ASSIGNED`, and the DB enforces ownership.
**The execution gate, the rendering surface, and the fail-closed claims** were
verified in review 589 and are untouched by the remediation commit; the diff
`433f66ad..53ce1b1` does not include `webui/console_authz.py`,
`webui/request_views.py`, or `webui/sanctioned_restart.py`.
Two non-blocking notes:
- `_sweep_session_leases` calls `list_leases` without a `limit`, taking the
default of 100 rows ordered by `expires_at DESC`. A lease this flow just
created has the furthest expiry, so it lands in range today; the sweep's
correctness depends on that ordering rather than stating it.
- `_accepts_session_id` omits `session_id` for an injected allocator whose
signature lacks it. That protects existing fakes, but a custom allocator that
creates leases under its own id makes the post-commit sweep a silent no-op.
The default path is unaffected.
## Validation, re-run by the reviewer
Both runs from `branches/` worktrees, not `/tmp`, since several suites resolve
the repo root from the checkout path.

NEXT_ACTION: Apply the allocator's expiry filter to the claim map the console reads, keeping the unparseable-expiry-is-kept rule; add a test with a past expires_at and status active asserting the preview authorizes; give the _claimed fixture a future expiry.
PROHIBITED_ACTIONS: Do not merge. Do not self-approve. Do not read the duplicate-assignment tests as proof the claim check is correct — their fixture expiry is in the past.
NEXT_PROMPT: Act as author on Scaled-Tech-Consulting/Gitea-Tools issue #643, PR #902, remote prgs. Read the reviewer REQUEST_CHANGES on PR #902 at head d0006e9f714b8754beead64e15d03f769e872543. B1 and B2 from review 589 are fixed and were independently mutation-tested; one new blocker was introduced by the B2 fix. B3: preview_request no longer triggers a lease sweep, which is correct, but default_claims_source still calls db.list_active_claims, which filters on l.status = 'active' alone and never compares expires_at. Before the fix, allocate_next_work's unconditional expire_stale_leases() ran inside the preview and flipped past-TTL rows to expired before _load_claims read them. Now nothing on the console path sweeps, so a lease whose TTL has passed while its row still reads active makes _lease_check fail with duplicate_assignment: the preview reports blocked and apply_request refuses 409 at the preview gate, while allocate_next_work(side_effect_free=True) drops that same claim through _drop_expired_claims and would select the unit. Fix by applying the same in-memory expiry filter to the claim map the console reads, in _load_claims or default_claims_source, preserving the rule that an unparseable expires_at is kept. Add a test with a control-plane lease row whose expires_at is in the past and whose status is still active, asserting the preview authorizes and apply reaches the allocator, and move tests/test_webui_request_initiation.py _claimed() to a future expires_at so the duplicate guard is tested against a live claim. Re-run WEBUI_TEST_OFFLINE=1 ../../venv/bin/python -m pytest tests/ -q from a branches/ worktree and compare against master 715863799f7b, which gives 23 failed / 5256 passed / 6 skipped / 914 subtests.

Summary
Implements Phase 2 request preview, authorization, and workflow initiation for the web console (Closes #643).
Operators had to paste a role prompt into a terminal to start work, and nothing enforced that the allocator had been consulted first, so two sessions could reach for the same issue and each believe it was theirs. This adds a request surface: a desired role, an issue or PR, and a stated intent, answered by an authorization decision and, on confirmation, an exclusive assignment from the allocator.

Closes #643

Apply runs the allocator twice, on purpose. The allocator is the only source of exclusive ownership (#600/#613), and it selects work rather than taking orders. So
applyruns a dry-run first and proceeds only when the allocator would independently pick the requested work unit; otherwise it returnswaitand mutates nothing. The apply call carries the dry-run'scandidate_set_fingerprintas a CAS pin (#776), and the result is re-checked on the way out so an assignment naming a different work unit is not read as success.The execution gate is action-scoped, not a phase bump.
console_authz.ConsoleActiongains an optionalexecution_env_flag, andauthorizenow computesexecution_enabledvia a newexecution_wired(action, env)helper. RaisingACTIVE_PHASEwould have enabled execution for every phase-2 action at once, includingsystem.restart_namespaceand the analytics ingest, whose execution paths are not implemented here.initiate_workflowis the only action declaring a flag (WEBUI_REQUESTS_EXECUTION); every other action keeps its previous behaviour and still reportsexecution_enabled: false.Operator-class authority.
initiate_workflowrequiresoperatorbecause its outcome is a claim, not a Gitea verdict. Requesting reviewer or merger work reserves that work; it grants no right to approve or merge, which stays with the MCP role profile.A denial is not a queue oracle. An unauthorized principal never reaches the allocator or the control-plane DB at all.
Fail-closed behaviour
An unreadable control-plane DB, an incomplete queue inventory (#758), an allocator that raises, an unpinned PR head, a PR head that moved, and an unconfirmed apply all deny without mutating. An unreadable claim inventory is never treated as "nothing holds this work unit".

The same 23 tests fail on both. This branch adds 52 passing tests and introduces no new full-suite failure signature. The baseline was run from a

Moderate. This introduces the console's first wired execution path, so review should focus on the execution gate and the allocator interaction. Mitigations: execution is off by default and requires an environment variable an operator must set; the assignment path cannot bypass the allocator; approve and merge remain forbidden in every path.

433f66adTwo code blockers, both in the initiation path. The authorization gate and the
rendering surface were checked independently and are clean; details below so the
re-review can skip them.
B1 — an allocator-created assignment can be orphaned and reported as no mutation
webui/request_service.py:745-781, withallocator_service.py:741-757,1101-1142,1339,1460-1513.Failure scenario, concrete:
WEBUI_REQUESTS_EXECUTION=1. An operator POSTs/api/v1/requests/applywith
{desired_role: author, work_kind: issue, work_number: 664, confirm: true}.apply_requestre-previews at line 720. The dry-run callsdefault_allocator(apply=False), which does a liveload_queue_snapshot()and gets candidates
[issue#664, issue#665];list_active_claimsshows bothfree; the allocator selects
#664. Fingerprintfp = sha256([{issue,664},{issue,665}]).concurrent session takes a lease on
#664. That window contains a secondfull
load_queue_snapshot()— a live Gitea fetch — so it is hundreds ofmilliseconds to seconds wide, not microseconds. Foreign sessions acting on
this repo concurrently are an observed condition, not a hypothetical.
_run_allocator(apply=True)re-runsdefault_allocator. The queue isunchanged, so
cas_fp == fpand the #776 CAS pin passes.candidate_set_fingerprint(allocator_service.py:741-757) hashes only{kind, number}plus exclusions. Lease state is not an input to it, andlease state is exactly what changed.
allocator_service.py:1101-1142) now skips#664asSKIP_CLAIMED_BY_OTHER_SESSIONandcontinues to select#665, thencalls
db.assign_and_leaseat line 1339. A durable assignment row and leaseon
#665are committed. It returnsoutcome=assigned_work,selected=#665.apply_request,_selection_matches(#665, request #664)is False,so
assignedis False and control reaches_refuse(...)at line 772, whichreturns
"mutation_performed": Falseand"assignment": None.Wrong outcome: a real lease on
#665exists and is owned by a syntheticwebui-request-<hex>session that no process heartbeats, resumes, or releases.Nothing in this path releases it.
#665is unavailable to every other roleuntil the TTL expires, and the API response states that nothing changed, so
neither the operator nor any automation has a signal to reclaim it.
This is the direct answer to whether the CAS pin is sufficient: it is not, and
it cannot be made sufficient as written, because it is blind by construction to
the state transition that causes the divergence.
Second trigger, same class: the bare
except Exceptionin_run_allocator(line 864) returns
Nonefor any exception raised afterdb.assign_and_leasehas committed.
allocate_next_work's own catch atallocator_service.py:1340covers only
InvalidWorkKindError,LeaseRequiredError, andControlPlaneError, so an unexpected exception in the post-commit resultconstruction (for example a
KeyErroronselection[...]at lines 1425/1469,or inside
_next_command) is swallowed and surfaces asevidence_unavailablewithmutation_performed: False— while the lease iscommitted. So that bare except can indeed swallow a successful-but-partial result.
Coverage is inverted rather than absent.
tests/test_webui_request_initiation.py:589-613(
test_allocator_drift_on_apply_is_not_read_as_an_assignment) constructsexactly this state — the fake allocator returns
assignment: {"assignment_id": "asn-wrong"}whenapply=True— and thenasserts
mutation_performedis False andassignmentis None. The testencodes the orphaned assignment as intended behaviour. No test asserts a
compensating release or any leak signal.
Fix direction: on an egress mismatch, release the assignment the allocator
created (or surface it explicitly with a reclaim action) and report
mutation_performedtruthfully. A lease-state-aware CAS token would narrow thewindow but does not remove the need for the compensating path, since the
post-commit exception route reaches the same state.
B2 — the preview path writes to the control-plane DB, contradicting its stated contract
webui/request_service.py:556-582and892-934, withallocator_service.py:888-912.Failure scenario, concrete:
/requestsand submits the preview form, or POSTs/api/v1/requests/preview. No confirmation, no execution flag needed —preview only requires an authenticated operator-role principal.
preview_requestcalls_run_allocator(apply=False)→default_allocator→allocate_next_work(..., apply=False).allocate_next_workcallsdb.upsert_session(session_id=..., role=..., profile=..., pid=os.getpid())atallocator_service.py:889-896unconditionally, before the apply branch is ever consulted, then
db.expire_stale_leases()at line 912.default_allocatormintsf"webui-request-{uuid.uuid4().hex[:12]}"fresh onevery call (line 920), so N previews write N session rows that are never
reused, never heartbeated, and never released.
Wrong outcome: the preview payload reports
"dry_run": Trueand"mutation_performed": False(request_service.py:296-297), the moduledocstring says "Read-only, always. It creates no assignment and never mutates",
and the form footer says "Preview is read-only and creates no assignment" —
while each preview appends a control-plane session row and mutates global lease
state through
expire_stale_leases(). Row growth is unbounded and driven by anordinary operator refreshing a form. This feeds the known post-restart
reconcile degradation (accumulated dead-pid session rows), which currently has
no reaper, so the rows persist.
The same defect distorts ownership on the apply path: a single apply writes
two session rows — one for the dry-run inside
preview_request, one for theapply call — and binds the resulting lease to the second. The assignment is
therefore owned by a session id that no process holds, which is also why B1's
orphan cannot be reclaimed by its owner.
Coverage is zero.
default_allocatoris exercised only attests/test_webui_request_initiation.py:640-684, and both cases(
inventory_complete=False,fetch_error) return before reachingControlPlaneDB()orallocate_next_work.default_claims_sourcehas no testat all. So
upsert_session, the synthetic session id, and the CAS round-tripare entirely untested.
Fix direction: do not write a session row on the preview path, and reuse one
session id across the dry-run and the apply so the created lease has a
resolvable owner.
Verified clean — no change requested
The execution gate did not loosen.
ACTIVE_PHASEis still1(
webui/console_authz.py:458). Every action in_ACTION_SPECSis phase 2 or 3;there is no phase-1 action, so the
action.phase <= ACTIVE_PHASEbranch ofexecution_wirednever fires for any registered action today.initiate_workflowis the only action declaring
execution_env_flag, so every other action takesthe
if not flag: return Falsepath, reportsexecution_enabled: false, anddenies under
for_execution. Checked specifically:system.restart_namespace(phase 2, no flag) denies, andwebui/sanctioned_restart.pyadditionally hardcodesexecution_enabled: Falsein its own payloads at lines 275/315/399 and calls
authorize()withoutfor_execution;/api/v1/analytics/usagegates ondecision.allowed and decision.execution_enabledatwebui/app.py:672forrecord_analytics_usage(phase 2, no flag), so it stays dead.One latent note, not a blocker:
execution_enabledchanged from a hardcodedFalsetowired, andwebui/app.py:672gates a real write on that field. Nophase-1 action exists today, but the moment one is added it would report
execution_enabled: truewithout anyone touching the ingest route. Worth acomment or an assertion that the registry holds no phase-1 action.
Rendering. Every interpolation in
webui/request_views.pypasses through_escape(html.escape(..., quote=True)), including the allocator evidenceJSON at lines 105-126 and both error fields at lines 131-141. Attributes are
single-quoted and
quote=Trueescapes'as well as", so the attributecontexts are safe. No injection path found. Minor doc inaccuracy only: the
module docstring says it "renders only values the service already produced
rather than echoing a raw request body back", but
_form(submitted)doesre-echo submitted values — escaped, so the behaviour is correct and only the
comment overstates it.
The self-check on
list_active_claims. It is redundant for safety andload-bearing only for reporting. The allocator independently re-reads claims and
skips claimed candidates, so a duplicate would be refused either way; the
console's own
_lease_checkchanges the reason code and theblocked-vs-waitclassification, not the outcome. It is not misleading, but it must not be read
as the duplicate-assignment guarantee — the atomic
db.assign_and_leaseis thatguarantee.
The fail-closed claims that hold. Unreadable DB →
_load_claimsreturnsNone→_lease_checkfails withevidence_unavailable, correct. Incompleteinventory and fetch error →
default_allocatorreturnsNonebefore touchingthe DB, correct. Unpinned and moved head →
_head_pin_checkfails, correct.Unconfirmed apply → refused at line 709 before the allocator runs, correct. The
allocator-exception claim is where it breaks down; see B1.

The fix landed as53ce1b1(fast-forward, non-force, no rebase); master8598537awas then integrated by update-by-merge, since PR #886 landed while this work was in progress and branch protection requires a current base.B1 — the apply path no longer leaves an assignment behind
The egress mismatch now releases what the allocator committed:
When the release succeeds the refusal reports
mutation_performed: falseplus acompensationrecord; when it fails the response carriesmutation_performed: true, an explicitorphaned_assignment, and agitea_release_workflow_leasereclaim action naming the lease and its owning session. Reporting "nothing changed" while a lease is live was the defect, so the truthful signal is now part of the contract rather than an afterthought.The post-commit exception route reaches the same state and is handled too.
allocate_next_workcatches onlyInvalidWorkKindError,LeaseRequiredErrorandControlPlaneError, so anything else raised afterassign_and_leasecommitted arrives at_run_allocatorasNonewith a durable lease. ANoneresult on the apply path now sweeps and releases whatever this flow's session owns. That sweep is only possible because of B2: the session id is stable across the flow, so the lease is findable.The CAS fingerprint itself is unchanged. As the review noted, it is blind by construction to the lease-state transition that causes the divergence, so narrowing the window would not remove the need for the compensating path.
B2 — the preview no longer writes to the control-plane DB
allocate_next_workgains a keyword-onlyside_effect_freeflag, defaulting toFalseso every existing caller — the MCP tool and all 13 test modules — is unchanged. Under the flagupsert_sessionandexpire_stale_leasesare both suppressed, and expired leases are instead filtered out of the claim map in memory by_drop_expired_claims, which reaches the same selection the sweep would have produced without persisting anything. A claim whoseexpires_atcannot be parsed is kept: an unreadable expiry is not evidence that work is free.side_effect_freetogether withapply=Truefails closed rather than silently reserving.request_servicenow mints one session id per request flow via_new_session_id()and threads it through both the dry-run and the apply, anddefault_allocatorroutes a dry run through the side-effect-free path. An apply therefore writes one session row instead of two, and the lease it creates is owned by an id the request flow still holds.Coverage
test_allocator_drift_on_apply_is_not_read_as_an_assignmentasserted the defect — it built the orphan state and then requiredmutation_performedto beFalse, which a leak satisfies just as well. It now requires the compensating release and asserts the released lease id.Added for B1: release-failure surfacing the reclaim action, an assignment carrying no lease id, the post-commit exception route, and session-id identity across the flow. Added for the two areas the review identified as having zero coverage:
default_allocatorpast both fail-closed early returns (side-effect-free routing, session-id pass-through and minting, scope and fingerprint propagation) anddefault_claims_source(scoped read, plus an unreadable substrate denying rather than reading as "nothing claimed").tests/test_allocator_service.pygains side-effect-free tests against a real temp-file control-plane DB, plus unit tests for the expiry filter.Every new guard was mutation-tested by reverting it one at a time in the worktree and restoring after each run:

WHAT_HAPPENED: An author session implemented both blockers from reviewer review 589 — the compensating release for an allocator-created assignment that fails the egress check, and a genuinely side-effect-free preview path — added regression coverage for each including the two zero-coverage areas the review named, corrected the drift test that asserted the defect, published the fix, and integrated master after PR #886 landed.
WHY: The apply path could commit an assignment for a different work unit than the one requested and then report that nothing was mutated, and the preview path wrote a control-plane session row and swept leases on every call while declaring itself read-only.

NEXT_ACTION: Route the claim map the console reads through the same expiry filter the allocator now applies, so a lease whose expires_at has passed while its row still reads status 'active' no longer denies preview and apply. Keep the rule that an unparseable expires_at is retained. Add coverage for an expired-but-unswept lease, and give the
_claimedfixture a future expires_at so the duplicate-assignment tests prove what their names say.NEXT_PROMPT:
WHAT_HAPPENED: Independent reviewer review of PR #902 at head
d0006e9f. The head moved twice during the session (433f66adto6da68ffftod0006e9f); both later commits are master merges, and the effective diff against master715863799fis content-identical across them — only blob ids and hunk offsets in webui/app.py and webui/nav.py shifted. Full suite re-run at the reviewed head and at a clean master baseline worktree, both under branches/. Four single-guard mutation runs against the new B1/B2 guards. One new blocker found, introduced by the B2 fix.WHY: The B2 fix removed the lease sweep from the preview path but left the console's own claim query filtering on lease status alone, so a lease past its TTL that no sweep has touched denies preview and apply for a work unit the allocator itself treats as unheld.

Server-side mutation ledger:
Review — PR #902 (#643), head
d0006e9fBoth prior blockers are genuinely fixed, and I confirmed each new guard by
reverting it and watching a test fail. The B2 fix, however, removed a write that
another code path was silently depending on, and that dependency is not covered.
One blocker, then the verification detail so the re-review can skip it.
B1 (review 589) — fixed
webui/request_service.py:783-861,_release_stray_assignmentat:960-1035,_sweep_session_leasesat:1063-1105.The egress mismatch now releases the assignment the allocator committed before
refusing. I traced the release end to end rather than trusting the shape:
allocation["assignment"]isAssignmentResult.as_dict(), which carrieslease_id(control_plane_db.py:333,352);ownerresolves fromallocation["session_id"], whichallocate_next_worksets to the id the callerpassed (
allocator_service.py:1449);release_leaserequiresrow["session_id"] == session_idand raisesForeignLeaseErrorotherwise(
control_plane_db.py:1805), so the ownership match is real rather than assumed.release_lease_recordedalso flips theassignmentsrow toreleasedandwrites a
lease_releasedevent (:1819-1858), so the compensation is completeand auditable, not lease-only.
The
waitandno_safe_workoutcomes also return a populatedassignmentdict, and
committedcorrectly gates onoutcome == OUTCOME_ASSIGNED, so aforeign lease surfaced under
waitis never released. That distinction mattersand it is right.
The release-failure branch reports
mutation_performed: Truewith an explicitorphaned_assignmentand agitea_release_workflow_leasereclaim action. Thatis the correct direction: a live lease reported as "nothing changed" was the
defect.
The post-commit exception route is handled by
_sweep_session_leases, which isonly sound because the session id is now stable across the flow — the two fixes
depend on each other, and the commit message says so.
Mutation-tested: removing the release body gives 2 failures
(
test_allocator_drift_on_apply_is_not_read_as_an_assignment,test_drift_whose_release_fails_reports_the_orphan_and_a_reclaim); stubbing outthe post-commit sweep gives 1
(
test_exception_after_commit_releases_the_session_lease). The drift test nolonger encodes the defect — it now asserts
released == ["lease-wrong"]andcompensation["released"].B2 (review 589) — fixed, and this is where B3 comes from
allocator_service.py:867-990,_drop_expired_claimsat:764-782,webui/request_service.py:1172(side_effect_free=not apply).allocate_next_workgains a keyword-onlyside_effect_free, defaultFalse,so every existing caller is unchanged; under the flag
upsert_sessionandexpire_stale_leasesare both suppressed, andside_effect_freewithapply=Truefails closed instead of quietly reserving. The session id is mintedonce per request flow and threaded through both halves. Keeping a claim whose
expires_atcannot be parsed is the right call — an unreadable expiry is notevidence that work is free.
Mutation-tested: ignoring the suppression gives 3 failures in
SideEffectFreeAllocationTest; re-minting the session id per call gives 1(
test_caller_session_id_is_passed_through_verbatim).B3 — an expired-but-unswept lease now denies work the allocator considers unheld
webui/request_service.py:1118-1127(default_claims_source) and:412-454(
_lease_check), againstallocator_service.py:764-782.The suppressed
expire_stale_leases()was doing double duty. Inpreview_requestthe allocator runs before_load_claims(
request_service.py:592-599), so at433f66adthe sweep flipped everypast-TTL lease to
expiredand the claim query that followed saw a clean view.The fix compensated for the missing sweep inside the allocator, via
_drop_expired_claims, but the console reads claims through its own path:default_claims_sourcecallsdb.list_active_claims, which filters onl.status = 'active'alone (control_plane_db.py:1616-1661,1694-1697) andnever compares
expires_at. Onlyexpire_stale_leasesandrequire_valid_assignmentflip those rows, and neither is on this path.Failure scenario, concrete:
the standard end state here; "let the TTL expire" is the routine advice.
expires_athas passed, but the row still readsstatus = 'active'because nothing has swept./requests, asks for author on issue #664, and submits._run_allocator(apply=False)runsside_effect_free, drops that claim inmemory, and selects #664 — the allocator's own view is that #664 is unheld.
_load_claimsthen callslist_active_claims, which still returns thelapsed lease.
_lease_checkfails withduplicate_assignment.authorizedis False, so the preview reportsblockedand cites an"active author lease" that expired ten minutes ago.
apply_requestrefuses409 at
:756-771, before the allocator is ever consulted on the apply.Wrong outcome: the console cannot initiate work on any unit carrying a lapsed
lease, and it reports contradictory evidence —
next_safe_actionpasses becausethe allocator selected the unit, while
lease_availabilityfails claiming theunit is held. Nothing in the console path clears the row, so the refusal is not
transient: it persists until some unrelated non-side-effect-free allocator call
happens to sweep. This is a regression against
433f66ad, where the preview's ownsweep cleared the row and the request proceeded.
Reproduced at this head against a real temp-file control-plane DB — one lease,
expires_at30 minutes in the past, status leftactive:And the sweep that used to run on the preview path is exactly what closed the
gap:
Coverage is zero, and the fixture actively hides it:
tests/test_webui_request_initiation.py:199-209_claimed()hard-codesexpires_at2026-07-25T09:10:37Z— a timestamp in the past. Everyduplicate-assignment assertion in the suite therefore proves that an expired
claim blocks, which is the behaviour at issue, and no test constructs a lapsed
row and asserts the request proceeds.
Fix direction: filter the console's claim map through the same expiry rule the
allocator now uses, in
_load_claimsordefault_claims_source, keeping theunparseable-expiry-is-kept rule. Then the two views agree by construction. Give
_claimed()a future expiry so the duplicate guard is tested against a liveclaim, and add a case with a past
expires_atandstatus = 'active'assertingthe preview authorizes.
Verified clean — no change requested
Scope. The effective diff against master is 11 files, exactly the stated
list. The two commits added since the reviewed
433f66adare master merges only:git diff master...HEADat6da68fffand atd0006e9fdiffer only in blob ids andhunk offsets for
webui/app.pyandwebui/nav.py; every added and removed lineis identical, so the merge resolution introduced nothing. The restart-class files
that appear in a two-dot diff come from #886 landing on master, not from this
branch.
The compensation cannot release someone else's lease. Covered under B1
above:
committedgates onOUTCOME_ASSIGNED, and the DB enforces ownership.The execution gate, the rendering surface, and the fail-closed claims were
verified in review 589 and are untouched by the remediation commit; the diff
433f66ad..53ce1b1does not includewebui/console_authz.py,webui/request_views.py, orwebui/sanctioned_restart.py.Two non-blocking notes:
_sweep_session_leasescallslist_leaseswithout alimit, taking thedefault of 100 rows ordered by
expires_at DESC. A lease this flow justcreated has the furthest expiry, so it lands in range today; the sweep's
correctness depends on that ordering rather than stating it.
_accepts_session_idomitssession_idfor an injected allocator whosesignature lacks it. That protects existing fakes, but a custom allocator that
creates leases under its own id makes the post-commit sweep a silent no-op.
The default path is unaffected.
