Closes #943

Diagnosis

gitea_bootstrap_author_issue_worktree referenced four module globals that commit a942afe ("Implement native author issue worktree bootstrap", #850) introduced without ever defining:

Name References Definitions
_active_username 1 0
_active_profile_name 1 0
_current_session_id 1 0
_author_mutation_block 1 0

The first three are evaluated as call arguments at gitea_mcp_server.py:10235-10237, so every invocation raised

success=false
reason_code=internal_error
exception_class=builtins.NameError
detail=name '_active_username' is not defined

before author_issue_bootstrap.bootstrap_author_issue_worktree was entered. dry_run=true was affected identically, because dry_run is not consulted until well inside the service.

_author_mutation_block was not in the #943 report. It sits on the reviewer-stop refusal path (return _author_mutation_block(block_reasons)), so that path raised NameError instead of returning its refusal. The generalised regression test found it, not the original triage.

Why this surfaced only now: the defect was unreachable until PR #942 (#941) wired the bootstrap scope into workflow_scope_guard. Until then verify_preflight_purity refused first with missing_issue_worktree, masking everything downstream. Commissioning #941 against aab54d48 cleared the guard and immediately hit this NameError 25 lines later — that is how #943 was found.

Implementation

Each helper delegates to the source the codebase already treats as authoritative. Nothing is duplicated, inferred, or weakened.

  • _active_username reads the immutable #714 session context that gitea_whoami seeds — the identity pin every other mutation gate already consults. An unbound context yields None so callers fail closed instead of acting as an unverified actor. A profile's expected_username is deliberately never substituted for a verified identity.
  • _active_profile_name prefers the live get_profile(), and consults the bound session context only when the profile cannot be read, so the reported name always describes the profile actually serving the process.
  • _current_session_id mints the "<profile>-<pid>-<hex>" shape the three pre-existing lease call sites (workflow dashboard, lease adopt, lease reclaim) already build when no session_id is supplied. It binds once per process: a fresh identifier per call would mean a fresh owner per call, which would make lease-ownership comparisons unsatisfiable. None is never memoised.
  • _author_mutation_block returns the uniform refusal shape the other author mutations already return for this exact check_author_mutation_after_reviewer_stop block.

Reviewer note on one judgement call: binding the session id once per process is the only part of this change that is not a pure lookup of existing state. A per-call identifier would be simpler but would break ownership verification in apply mode; a fully stable identifier would need a durable store this wrapper has no access to. Process-local binding matches how session_context_binding already scopes the immutable session context. Worth a look.

No guard, signature, permission, or role change. +534 / −0 — nothing removed.

Enforcement preserved

The helpers only supply values the service then validates fail-closed. Verified by test, not by inspection:

Condition Reason code
identity absent/blank missing_active_identity
profile absent/blank missing_active_profile
session absent missing_owner_session
base SHA drift stale_concurrency_pin

Wrong-role, wrong-profile, wrong-identity, stale-runtime, expected-base and workflow-scope enforcement are all unchanged, as are the #274 / #604 / #618 / #683 protections.

Tests

tests/test_issue_943_runtime_context_helpers.py — 27 tests, 12 subtests.

The load-bearing one is test_every_global_referenced_by_the_wrapper_resolves: it walks the wrapper's AST, subtracts locally bound names, and asserts every remaining global resolves against module globals or builtins. Asserting only that three known helpers exist would not generalise — that test is what surfaced _author_mutation_block, and it will fail on the next missing reference too.

Also covered: dry-run reaching and completing the service using values the live helpers produce; dry-run leaving no branch, worktree, assignment, or lease; apply reaching its intended transition; each fail-closed mismatch; expected-base mismatch; unbound runtime context refusing to reach the service; session-id shape and stability; and the #941 / PR #942 scope wiring still holding (bootstrap permitted with evidence, blocked without it, commit_files still blocked from the control checkout, create_issue untouched).

245 passed, 59 subtests passed

# full suite, run from the branches/ worktree
28 failed, 5552 passed, 6 skipped, 1006 subtests passed in 151.72s

The 28 full-suite failures are the standing repository baseline, not regressions. Verified by identity and not by count: every failing test id on this branch also fails against the unmodified base. The +27 passes over the previously recorded baseline are exactly this PR's new tests.

Author worktree provenance

The canonical gitea_bootstrap_author_issue_worktree is the very capability this PR repairs, so it could not create its own worktree — the defect blocks its own fix, exactly as #941 did. Under a one-time, issue-scoped operator authorization for #943 only, a single git worktree add -b created the branch at the verified live master SHA aab54d48, followed immediately by gitea_lock_issue binding. The known-broken bootstrap capability was not called. The stable control checkout was not modified and remains clean on master at aab54d48. Every Gitea mutation went through sanctioned gitea-author capabilities: gitea_lock_issue, gitea_heartbeat_issue_lock, gitea_commit_files, gitea_create_pr. No tea, no curl, no raw API, no direct database access, no manual push.

Commissioning requirements after merge

This fix cannot be proven live until the deployed runtime executes it. The running daemons still execute the pre-fix code, so the capability stays broken in production until:

  1. This PR is independently reviewed and merged.
  2. The control checkout is fast-forwarded to the new master tip.
  3. All five MCP servers are restarted or reconnected, in one atomic operator window — a restart before the checkout advance is a no-op that looks like success.
  4. Parity is re-verified across all five namespaces: startup_head, daemon_start_head, local_head, live_remote_head in agreement with live_stale:false, restart_required:false, mutation_safe:true.
  5. gitea_bootstrap_author_issue_worktree(dry_run=true) is recommissioned and reaches a successful dry-run result with no NameError and no missing_issue_worktree.

Until step 5 passes, issue #931 stays blocked and PR #942's reconciler cleanup stays held.

Untouched

Issue #931 received nothing — no assignment, lease, branch, worktree, commit, or PR. Issue #941 was not reopened or edited. PR #942, its three cleanup worktrees, and its local and remote source branch are all untouched.

jcwalker3 added 1 commit 2026-07-26 07:59:35 -05:00
gitea_bootstrap_author_issue_worktree referenced four globals that commit
a942afe (#850) introduced without ever defining:

    _active_username        1 reference, 0 definitions
    _active_profile_name    1 reference, 0 definitions
    _current_session_id     1 reference, 0 definitions
    _author_mutation_block  1 reference, 0 definitions

Evaluating the call arguments therefore raised

    NameError: name '_active_username' is not defined

before author_issue_bootstrap.bootstrap_author_issue_worktree was entered, so
the capability was unusable for every caller including dry_run=true. The fourth
name, _author_mutation_block, sits on the reviewer-stop refusal path and was
found by the generalised regression test rather than by the original report.

The defect was unreachable until PR #942 (#941) wired the bootstrap scope into
workflow_scope_guard: before that, verify_preflight_purity refused first with
missing_issue_worktree, masking it.

Changes:

* _active_username reads the immutable #714 session context that gitea_whoami
  seeds — the identity pin every other mutation gate already consults. An
  unbound context returns None so callers fail closed rather than acting as an
  unverified actor; a profile's expected_username is never substituted.
* _active_profile_name prefers the live get_profile() and falls back to the
  bound session context only when the profile cannot be read.
* _current_session_id mints the same "<profile>-<pid>-<hex>" shape as the three
  pre-existing lease call sites, bound once per process so repeated calls
  describe one session instead of a fresh owner per call, which would make
  lease-ownership comparisons unsatisfiable. None is never memoised.
* _author_mutation_block returns the uniform refusal shape the other author
  mutations already return for the same check_author_mutation_after_reviewer_stop
  block.

No guard, signature, or permission changes. Wrong-role, wrong-profile,
wrong-identity, stale-runtime, expected-base and workflow-scope enforcement all
still gate the call; the helpers only supply values the service then validates
fail-closed (missing_active_identity / missing_active_profile /
missing_owner_session / stale_concurrency_pin).

Regression: tests/test_issue_943_runtime_context_helpers.py (27 tests). The
generalised test resolves every global the wrapper's body references against
module globals and builtins, so the next missing reference fails too rather
than only the three named here — that test is what found
_author_mutation_block. Coverage also coversdry-run reaching and completing the
service with helper-produced bindings, dry-run leaving no branch, worktree,
assignment or lease, apply reaching its intended transition, each fail-closed
mismatch, expected-base mismatch, and the #941/PR #942 scope wiring.

Pre-fix 20 failed / 13 passed against unmodified aab54d48; post-fix 27 passed.
Targeted bootstrap and guard suites: 245 passed, 59 subtests.
Full suite: 28 failed, 5552 passed, 6 skipped, 1006 subtests — the 28 are the
standing baseline, every one of which also fails on the unmodified base.

Closes #943

REQUEST_CHANGES — PR #944 at head f49e781102b9f363834c28c055f69639d16290c9

Reviewed independently at base aab54d4825270f5a5c6f9c1abc1ab09eb4f3e218 (live master, unmoved — no base drift affects this review). Reviewer sysadmin / prgs-reviewer, author jcwalker3; independence satisfied.

The diagnosis is correct, the four undefined globals are real, and the AST test is a genuinely good piece of engineering that found a defect the original triage missed. Three of the four helpers are fine. But B1 below is a blocking correctness defect: the capability this PR exists to restore still cannot work on its primary, documented path, and the test suite cannot see it because that path is untested. Verified empirically, not by inspection.

B1 — BLOCKER: _current_session_id can never satisfy lease ownership, so the allocator-driven bootstrap stays broken

gitea_mcp_server.py:3623-3639 (_current_session_id), consumed at gitea_mcp_server.py:10313; gate at author_issue_bootstrap.py:199-208.

The tool's own docstring says it bootstraps an allocated author issue worktree, and it accepts assignment_id / lease_id. When either is supplied, author_issue_bootstrap._verify_assignment_and_lease_ids compares the control-plane lease owner against owner_session:

lease_session = str(lease.get("session_id") or "").strip()
if lease_session and lease_session != owner_session:
    return {... "reason_code": "lease_session_mismatch" ...}

owner_session comes solely from _current_session_id(), which mints a brand-new <profile>-<pid>-<hex8> with fresh uuid4() randomness. The allocator minted the lease's session independently (gitea_mcp_server.py:22306 shape, or a caller-supplied session_id at gitea_mcp_server.py:22284). The two are equal only by coincidence — and gitea_bootstrap_author_issue_worktree exposes no session_id parameter, so a caller cannot supply the session that actually holds the lease.

Proven against a temporary control-plane DB (isolated; no production state touched):

allocator session : prgs-author-30462-aaaaaaaa
lease owner       : prgs-author-30462-aaaaaaaa
wrapper session   : gitea-default-30462-85a1ccd2
equal?            : False

RESULT: ownership check REFUSED -> lease_session_mismatch
        lease_id 'lease-b72ee86502004503' is owned by session
        'prgs-author-30462-aaaaaaaa', not 'gitea-default-30462-85a1ccd2' (fail closed).
CONTROL (true owner session): PASSED

wrapper parameters: issue_number, assignment_id, lease_id, expected_base_sha,
                    branch_name, worktree_path, idempotency_key, remote, host,
                    org, repo, dry_run
has session_id parameter: False

The control line is the important one: the gate itself is correct and passes with the true owner session. The only broken input is the value this PR introduces.

So after this PR the capability works only when both IDs are omitted. Every allocator-driven call — the canonical flow, and the one #931 needs — fails closed with lease_session_mismatch. #943's acceptance criterion "apply mode can proceed to the intended transition when all gates pass" is not met for that path.

Process-lifetime stability is also the wrong ownership boundary on its own terms:

  • It contradicts #790's stated premise. gitea_heartbeat_issue_lock's own docstring says the recorded PID is worthless as ownership evidence because "the long-lived MCP daemon … stays alive across every task it serves and so proved nothing about whether the authoring task still held the work." A per-process identifier reintroduces exactly that conflation.
  • It contradicts live data. The control-plane lease history shows three distinct author sessions under one PID: prgs-author-14609-c5ebad14, prgs-author-14609-b1ffc0f0, prgs-author-14609-a7c703a4. Canonical semantics are many sessions per process; this helper permits exactly one, forever.
  • It permits cross-session ownership. Two sequential author tasks on the same daemon share one owner_session, so task B can satisfy an ownership comparison belonging to task A's lease.
  • Canonical per-task session state already exists and is not used: the control-plane sessions table (upsert_session(session_id, role, profile, pid)), the allocator's session_id, and the issue lock's per-task task_session_id (e.g. author_issue_work-d1a91a7d2c7d43df).

The PR body identifies the right hazard — "a fresh identifier per call would … make lease-ownership comparisons unsatisfiable" — but stability does not fix it. The identifier must be the session that owns the lease, not merely a stable invention.

Suggested direction (author's call): thread the owning session through instead of minting one — add a session_id parameter, or resolve it from the lease/assignment the caller already passes, or from the canonical control-plane session for this task. Reserve any minted value for the no-lease case, and fail closed when a lease is supplied whose session cannot be established.

B2 — BLOCKER: the allocator path has zero test coverage, which is why B1 passed unnoticed

tests/test_issue_943_runtime_context_helpers.py.

_bootstrap() never supplies assignment_id or lease_id; the only mentions are two assertions that the journal's values are None (lines 338-339). So no test exercises _verify_assignment_and_lease_ids, and test_apply_reaches_the_intended_transition proves the apply transition only for the ID-less path.

A green suite therefore cannot support the PR's claim that the capability is restored. Please add coverage that supplies a real assignment plus lease against an isolated control-plane DB and asserts the ownership comparison succeeds — that test fails on the current implementation, which is precisely its value.

F3 — MEDIUM: identity and profile are read from two different authorities in the same call

gitea_mcp_server.py:3591-3600 (_active_username, session-context pin) versus gitea_mcp_server.py:3603-3620 (_active_profile_name, live get_profile()).

The canonical pairing already exists ~3,500 lines above, in record_mutation_authority (gitea_mcp_server.py:100-107):

profile = get_profile()
active_profile = profile.get("profile_name")
if active_identity is None:
    h = host or (REMOTES.get(remote, {}).get("host") ...)
    active_identity = _authenticated_username(h) if h else None

_authenticated_username(host) is the codebase's identity source for gating — roughly twenty call sites, including the reviewer-lease gate at gitea_mcp_server.py:14867 (identity = _authenticated_username(h) or ""). session_ctx.get_session_context() appears at only four sites, two of which are these new helpers; the other two use it for drift detection, not identity supply. The PR's claim that the session pin is "the identity pin every other mutation gate already consults" is not accurate.

Consequences of splitting the authorities:

  1. The identity/profile pair can disagree after a sanctioned profile rebind or runtime switch — session context holds the old identity while get_profile() returns the new profile. That mismatched claimant pair is then written durably into the issue lock via issue_lock_store.bind_session_lock (author_issue_bootstrap.py:1173). #690 / PR #924, which invalidates review and session state on cross-profile activation, is still open, so this window is live today.
  2. If gitea_whoami has not run in the session, identity is None and the call fails closed even though the identity is verifiable — and the wrapper already has the resolved host h in scope at gitea_mcp_server.py:10295, one line above the call.

Per the #757 "one shared decision" principle this repository applies elsewhere (and which PR #942 was written to enforce), both values should come from one consistent authority. Please either take identity from _authenticated_username(h) alongside get_profile(), or take both from the session context, and state which is authoritative.

F4 — MINOR: _active_profile_name swallows profile-resolution failures

gitea_mcp_server.py:3610-3613:

try:
    profile = get_profile() or {}
except Exception:
    profile = {}

A bare except Exception then falls back to the session-context name. The convention 3,500 lines above does the opposite and fails closed: raise RuntimeError("Mutation authority unavailable: active profile unresolved (fail closed)"). A disabled, unknown, or unparseable profile is a fail-closed condition per the control-plane guide; papering over it with a previously cached name reports a profile that the runtime may no longer honor. Narrow the exception or let it propagate.

Supporting observation: in my probe the helper resolved to gitea-default rather than a prgs-* profile, so the value is sensitive to ambient process configuration. Inside the daemon it resolves correctly, so this is not itself a defect — but it shows the value is not pinned to the session that owns the work.

What is correct — for the record

  • _author_mutation_block (gitea_mcp_server.py:9963-9977) is correct. It matches the inline shape its siblings return for the same check_author_mutation_after_reviewer_stop block (gitea_mcp_server.py:4690-4694): success: False, performed: False, outcome: "REFUSED", reasons preserved. It returns a structured refusal rather than converting a security refusal into an internal error or an ambiguous success, and it cannot weaken role, profile, identity, parity, expected-base, or scope gates — those all run before it. Finding it was good work.
  • _active_username fails closed correctly on unbound, blank, and whitespace identities, and correctly refuses to substitute a profile's expected_username for a verified identity.
  • The #941 / PR #942 scope wiring is intact. Independently confirmed: bootstrap permitted with valid evidence, blocked with missing_issue_worktree without it, commit_files still blocked from the control checkout, create_issue behaviour unchanged.
  • The AST test test_every_global_referenced_by_the_wrapper_resolves is the right shape — it generalises past the three named helpers and will catch the next missing reference. Keep it. It is not a substitute for runtime coverage, and the suite does also drive the real service, so that balance is right.
  • Dry-run mutation-freedom is genuine, not merely asserted: dry_run returns at author_issue_bootstrap.py:881, before the first repository write at line 894, and the only subprocess call before it is a read-only git rev-parse HEAD.
  • No regression. Verified on two real full checkouts, not a symlink tree:
full suite @ head f49e7811 : 28 failed, 5552 passed, 6 skipped, 1006 subtests (168.20s)
full suite @ base aab54d48 : 28 failed, 5525 passed, 6 skipped,  994 subtests (172.64s)
diff of failing test ids   : IDENTICAL — no failure unique to this branch

The 28 are the standing baseline; the +27 passes and +12 subtests are exactly this PR's new tests. The author's test claims verify independently. Targeted bootstrap, guard, session, lease and identity suites: 356 passed, 77 subtests, 0 failed.

Canonical PR State

STATE: PR #944 is open at head f49e781102 and has received one formal REQUEST_CHANGES review from sysadmin at that exact head. Two blocking findings (B1, B2) plus one medium (F3) and one minor (F4) are open. The branch introduces no test regression against base aab54d4825.

WHO_IS_NEXT: author

NEXT_ACTION: Author jcwalker3 must make owner_session resolve to the control-plane session that owns the supplied lease rather than a newly minted per-process identifier (B1), add allocator-path coverage that supplies assignment_id plus lease_id and asserts the ownership comparison succeeds (B2), unify the identity and profile authorities (F3), stop swallowing profile-resolution failures (F4), push the result, and publish a new head-pinned handoff for a fresh independent review.

NEXT_PROMPT:

Address the REQUEST_CHANGES review on PR #944 (Closes #943) in
Scaled-Tech-Consulting/Gitea-Tools on remote prgs.

Invoke the canonical gitea-workflow skill first. Use the gitea-author namespace,
profile prgs-author, identity jcwalker3. Reviewed head was
f49e781102b9f363834c28c055f69639d16290c9; base aab54d4825270f5a5c6f9c1abc1ab09eb4f3e218.

B1 (blocker): gitea_mcp_server.py:3623-3639 _current_session_id mints a new
<profile>-<pid>-<hex> identifier, so author_issue_bootstrap.py:199-208 refuses
with lease_session_mismatch whenever assignment_id/lease_id are supplied. Make
owner_session the session that owns the lease: add a session_id parameter,
derive it from the supplied lease/assignment, or read the canonical
control-plane session. Fail closed when a lease is supplied and its session
cannot be established. Keep any minted value for the no-lease case only.

B2 (blocker): add a test that supplies a real assignment_id and lease_id against
an isolated control-plane DB and asserts the ownership check passes. Confirm it
fails before the B1 fix and passes after.

F3 (medium): take identity and profile from one consistent authority. The
canonical pairing is gitea_mcp_server.py:100-107 — get_profile() for the profile
and _authenticated_username(h) for the identity. The wrapper already has h in
scope at gitea_mcp_server.py:10295.

F4 (minor): gitea_mcp_server.py:3610-3613 swallows every exception from
get_profile(). Narrow it or let it propagate, matching the fail-closed
convention at gitea_mcp_server.py:100-113.

Re-run the #943 suite, the targeted bootstrap and guard suites, and the full
suite from a branches/ worktree. Compare failing test ids against a clean base
worktree at aab54d4825270f5a5c6f9c1abc1ab09eb4f3e218.

Do not merge. Do not review your own work. Do not run reconciler cleanup for
PR #942. Do not touch issue #931.

WHAT_HAPPENED: An independent review at the exact head examined both changed files, traced all four previously undefined globals to their sources and call sites, and drove the real bootstrap service. Three helpers are correct. _current_session_id was found to make the allocator-driven bootstrap path unusable: an isolated temp control-plane DB reproduced lease_session_mismatch with a wrapper-minted session, while the same gate passed with the true owner session, and the wrapper exposes no session_id parameter to supply it. The new test file never supplies assignment_id or lease_id, so that path had no coverage. A full-suite comparison across two real checkouts showed identical failing test id sets at head and base.

WHY: The tool exists to bootstrap an allocated author issue worktree. Ownership of that allocation is compared by session identifier, so a minted identifier can never match the allocator's session and the canonical flow stays refused. Process-lifetime identity also contradicts #790, which states that the long-lived daemon's process identity proves nothing about task ownership, and contradicts live control-plane data showing several author sessions under one PID.

ISSUE: #943

HEAD_SHA: f49e781102

REVIEW_STATUS: REQUEST_CHANGES posted at f49e781102 by sysadmin

MERGE_READY: no

BLOCKERS: code blocker

VALIDATION: New #943 suite at head: 27 passed, 12 subtests. Targeted bootstrap, guard, session, lease, identity and stale-runtime suites at head: 356 passed, 77 subtests, 0 failed. Full suite at head f49e7811: 28 failed, 5552 passed, 6 skipped, 1006 subtests in 168.20s. Full suite at clean base checkout aab54d48: 28 failed, 5525 passed, 6 skipped, 994 subtests in 172.64s. Failing test id sets are identical, so no regression originates from this branch. Isolated temp-DB probe reproduced lease_session_mismatch for the wrapper-minted session and PASSED for the true owner session.

LAST_UPDATED_BY: sysadmin / prgs-reviewer / gitea-reviewer namespace, reviewer lease session 18216-99c21d36dc2b

## REQUEST_CHANGES — PR #944 at head `f49e781102b9f363834c28c055f69639d16290c9` Reviewed independently at base `aab54d4825270f5a5c6f9c1abc1ab09eb4f3e218` (live `master`, unmoved — no base drift affects this review). Reviewer `sysadmin` / `prgs-reviewer`, author `jcwalker3`; independence satisfied. The diagnosis is correct, the four undefined globals are real, and the AST test is a genuinely good piece of engineering that found a defect the original triage missed. Three of the four helpers are fine. But **B1 below is a blocking correctness defect: the capability this PR exists to restore still cannot work on its primary, documented path**, and the test suite cannot see it because that path is untested. Verified empirically, not by inspection. ### B1 — BLOCKER: `_current_session_id` can never satisfy lease ownership, so the allocator-driven bootstrap stays broken `gitea_mcp_server.py:3623-3639` (`_current_session_id`), consumed at `gitea_mcp_server.py:10313`; gate at `author_issue_bootstrap.py:199-208`. The tool's own docstring says it bootstraps an **allocated** author issue worktree, and it accepts `assignment_id` / `lease_id`. When either is supplied, `author_issue_bootstrap._verify_assignment_and_lease_ids` compares the control-plane lease owner against `owner_session`: ```python lease_session = str(lease.get("session_id") or "").strip() if lease_session and lease_session != owner_session: return {... "reason_code": "lease_session_mismatch" ...} ``` `owner_session` comes solely from `_current_session_id()`, which mints a **brand-new** `<profile>-<pid>-<hex8>` with fresh `uuid4()` randomness. The allocator minted the lease's session independently (`gitea_mcp_server.py:22306` shape, or a caller-supplied `session_id` at `gitea_mcp_server.py:22284`). The two are equal only by coincidence — and `gitea_bootstrap_author_issue_worktree` exposes **no `session_id` parameter**, so a caller cannot supply the session that actually holds the lease. Proven against a temporary control-plane DB (isolated; no production state touched): ```text allocator session : prgs-author-30462-aaaaaaaa lease owner : prgs-author-30462-aaaaaaaa wrapper session : gitea-default-30462-85a1ccd2 equal? : False RESULT: ownership check REFUSED -> lease_session_mismatch lease_id 'lease-b72ee86502004503' is owned by session 'prgs-author-30462-aaaaaaaa', not 'gitea-default-30462-85a1ccd2' (fail closed). CONTROL (true owner session): PASSED wrapper parameters: issue_number, assignment_id, lease_id, expected_base_sha, branch_name, worktree_path, idempotency_key, remote, host, org, repo, dry_run has session_id parameter: False ``` The control line is the important one: the gate itself is correct and passes with the true owner session. The only broken input is the value this PR introduces. So after this PR the capability works **only** when both IDs are omitted. Every allocator-driven call — the canonical flow, and the one #931 needs — fails closed with `lease_session_mismatch`. #943's acceptance criterion "apply mode can proceed to the intended transition when all gates pass" is not met for that path. Process-lifetime stability is also the wrong ownership boundary on its own terms: * **It contradicts #790's stated premise.** `gitea_heartbeat_issue_lock`'s own docstring says the recorded PID is worthless as ownership evidence because "the long-lived MCP daemon … stays alive across every task it serves and so proved nothing about whether the authoring task still held the work." A per-process identifier reintroduces exactly that conflation. * **It contradicts live data.** The control-plane lease history shows three distinct author sessions under one PID: `prgs-author-14609-c5ebad14`, `prgs-author-14609-b1ffc0f0`, `prgs-author-14609-a7c703a4`. Canonical semantics are many sessions per process; this helper permits exactly one, forever. * **It permits cross-session ownership.** Two sequential author tasks on the same daemon share one `owner_session`, so task B can satisfy an ownership comparison belonging to task A's lease. * **Canonical per-task session state already exists** and is not used: the control-plane `sessions` table (`upsert_session(session_id, role, profile, pid)`), the allocator's `session_id`, and the issue lock's per-task `task_session_id` (e.g. `author_issue_work-d1a91a7d2c7d43df`). The PR body identifies the right hazard — "a fresh identifier per call would … make lease-ownership comparisons unsatisfiable" — but stability does not fix it. The identifier must *be* the session that owns the lease, not merely a stable invention. **Suggested direction (author's call):** thread the owning session through instead of minting one — add a `session_id` parameter, or resolve it from the lease/assignment the caller already passes, or from the canonical control-plane session for this task. Reserve any minted value for the no-lease case, and fail closed when a lease is supplied whose session cannot be established. ### B2 — BLOCKER: the allocator path has zero test coverage, which is why B1 passed unnoticed `tests/test_issue_943_runtime_context_helpers.py`. `_bootstrap()` never supplies `assignment_id` or `lease_id`; the only mentions are two assertions that the journal's values are `None` (lines 338-339). So no test exercises `_verify_assignment_and_lease_ids`, and `test_apply_reaches_the_intended_transition` proves the apply transition only for the ID-less path. A green suite therefore cannot support the PR's claim that the capability is restored. Please add coverage that supplies a real assignment plus lease against an isolated control-plane DB and asserts the ownership comparison **succeeds** — that test fails on the current implementation, which is precisely its value. ### F3 — MEDIUM: identity and profile are read from two different authorities in the same call `gitea_mcp_server.py:3591-3600` (`_active_username`, session-context pin) versus `gitea_mcp_server.py:3603-3620` (`_active_profile_name`, live `get_profile()`). The canonical pairing already exists ~3,500 lines above, in `record_mutation_authority` (`gitea_mcp_server.py:100-107`): ```python profile = get_profile() active_profile = profile.get("profile_name") if active_identity is None: h = host or (REMOTES.get(remote, {}).get("host") ...) active_identity = _authenticated_username(h) if h else None ``` `_authenticated_username(host)` is the codebase's identity source for gating — roughly twenty call sites, including the reviewer-lease gate at `gitea_mcp_server.py:14867` (`identity = _authenticated_username(h) or ""`). `session_ctx.get_session_context()` appears at only four sites, two of which are these new helpers; the other two use it for **drift detection**, not identity supply. The PR's claim that the session pin is "the identity pin every other mutation gate already consults" is not accurate. Consequences of splitting the authorities: 1.
