fix(author bootstrap): restore missing runtime identity and session helpers (Closes #943 )

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.

 # Remote-MCP coupling inventory
 Every place the Gitea MCP server depends on being a local, client-spawned, stdio-attached
 process on the operator's machine.
 - **Issue:** #930 (Remote-MCP 01), child 1 of epic #929.
 - **Generated against commit:** `7bf4f1258451823a55b36d2157e74f8457165088` (`master`).
 - **Anchors:** every `file:line` below resolves at the commit above and at the commit that
  adds this document. This change adds one new file and edits no existing file, so no
  existing line number shifts between the two.
 - **Scope:** documentation only. No server behavior changes in this child.
 ## How to read an entry
 | Field | Meaning |
 | ----- | ------- |
 | **Anchor** | `file:line` at the commit under review. |
 | **Assumes today** | What the code takes for granted while running as a local stdio process. |
 | **Observes remotely** | What the same code would actually see on a shared remote host. |
 | **Class** | One of: *portable as written*, *needs a seam*, *needs a replacement*, *cannot be remote*. |
 | **Owner** | Exactly one epic child (#931–#939) responsible for the fix. |
 Classification meanings:
 - **portable as written** — the code is already transport-, host-, and principal-neutral; it
  moves unchanged once its inputs are supplied by a remote-aware caller.
 - **needs a seam** — the logic is correct but is wired to a hard-coded local source. It needs
  an injection point, not new semantics.
 - **needs a replacement** — the semantics themselves are local-only. A remote deployment
  needs a differently-defined mechanism, not the same mechanism relocated.
 - **cannot be remote** — the operation is inherently about the operator's own machine
  (its process table, its keychain, its checkout). It must either stay local behind an
  explicit boundary or be deleted from the remote surface.
 ---
 ## 1. Transport bind
 The transport is bound literally, once, at process start, and the bound value is the root of
 the mutation-authorization chain.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | T1 | `gitea_mcp_server.py:23750` | The single production bind call passes the literal `transport="stdio"` immediately before the server loop. | The literal is wrong for any non-stdio deployment; there is no parameter to change it. | needs a seam | #931 |
 | T2 | `mcp_daemon_guard.py:45` | `_PRODUCTION_TRANSPORTS = frozenset({"stdio"})` is the closed allowlist of production transports. | A remote transport name is rejected by the allowlist before any other check runs. | needs a seam | #931 |
 | T3 | `mcp_daemon_guard.py:174` | `bind_native_mcp_transport` raises `UnsanctionedRuntimeError` for any transport outside `_PRODUCTION_TRANSPORTS` (raise at `mcp_daemon_guard.py:187`). | The remote server fails to start rather than degrading; the failure is correct, but the allowlist is the only thing that must change. | needs a seam | #931 |
 | T4 | `mcp_daemon_guard.py:328` | `is_native_mcp_transport()` asserts a process-local runtime record whose `pid` matches `os.getpid()` and whose phase is `transport_bound`. The predicate itself names no transport. | Unchanged semantics: one server process that bound one transport. It stays true on a remote host. | portable as written | #931 |
 | T5 | `mcp_daemon_guard.py:349` | `is_production_native_mcp_transport()` adds only a `mode == production` check on top of T4. | Unchanged. | portable as written | #931 |
 | T6 | `irrecoverable_provenance.py:497` | `assess_transport_for_auth_mint()` requires production native transport before minting non-forgeable recovery authorization (#709 F1). | The gate is transport-agnostic in form, but its guarantee — "an ordinary Python process cannot reach this" — is currently underwritten by the stdio bind. Under a remote transport the guarantee must be re-derived from the authenticated session, not from the bind. | needs a seam | #931 |
 | T7 | `gitea_mcp_server.py:8375` | Consumer: refuses to proceed unless `assess_transport_for_auth_mint()` allows. | Unchanged given a corrected T6. | portable as written | #931 |
 | T8 | `gitea_mcp_server.py:8624` | Second consumer of the same gate on the confirmation path. | Unchanged given a corrected T6. | portable as written | #931 |
 | T9 | `mcp_server.py:4` | Module docstring asserts "Runs over stdio." as a property of the server. | The stated contract becomes false on the remote deployment and is load-bearing documentation for operators. | needs a replacement | #931 |
 ## 2. Launch provenance
 Mutations fail closed unless the process can prove a client launched it with real stdio pipes
 and `GITEA_CLIENT_MANAGED` provenance. Every proof in this section is a statement about the
 local operating system.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | P1 | `gitea_mcp_server.py:14588` | `_is_client_managed_process()` derives provenance from `GITEA_CLIENT_MANAGED` / `GITEA_MCP_CLIENT_MANAGED` / `GITEA_SERVER_PROVENANCE` / `GITEA_FORCE_CLIENT_MANAGED` on this process's own environment. | A long-lived remote process has one environment for all callers, so a per-process env var can no longer say anything about the caller that issued a request. | needs a replacement | #934 |
 | P2 | `gitea_mcp_server.py:14606` | Falls back to `sys.stdin.isatty()`: an active TTY on stdin means a human launched it from a terminal, so refuse. | A remote server has no meaningful stdin. The signal is absent, not merely different. | cannot be remote | #934 |
 | P3 | `gitea_mcp_server.py:14618` | `_provenance_mutation_block()` emits `blocker_kind: "unsupported_manual_launch"` and a "reconnect the IDE/client-managed MCP namespace" remediation. | The block shape is reusable; its predicate and its remediation text are both stdio-specific. | needs a seam | #934 |
 | P4 | `gitea_mcp_server.py:20599` | `_check_mcp_runtimes_diagnostics()` shells `ps -o pid,lstart,command -ax` and greps for `mcp_server.py` to find peer role servers. | On a shared host the process table lists unrelated tenants' processes, or none at all under a container. Peer discovery by `ps` has no remote meaning. | cannot be remote | #934 |
 | P5 | `gitea_mcp_server.py:20702` | More than one process per `GITEA_MCP_PROFILE` in the local process table is reported as a duplicate-launch fault. | A remote endpoint is expected to serve many concurrent sessions per role. "Two processes for one role" becomes the normal case, so the check inverts from a safety net into a false wall. | cannot be remote | #934 |
 | P6 | `gitea_mcp_server.py:20715` | Processes lacking client-managed provenance are ignored for runtime freshness and reported as manual launches. | Same defect as P5: correctness depends on enumerating local peers. | cannot be remote | #934 |
 | P7 | `gitea_config.py:1172` | `RECOGNIZED_GITEA_ENV_KEYS` is the allowlist of `GITEA_*` env vars a legitimately launched server may carry; anything else is contamination. | Configuration on a remote host arrives from deployment tooling, not from a client-authored env block. The allowlist keeps working mechanically but stops proving anything about provenance. | needs a replacement | #934 |
 | P8 | `gitea_mcp_server.py:20683` | The unsupported-env scan applies `RECOGNIZED_GITEA_ENV_KEYS` to *other* processes' environments harvested via `ps eww <pid>`. | Reading another process's environment is unavailable or prohibited across tenants, and is not exposed in this form outside macOS/BSD `ps`. | cannot be remote | #934 |
 | P9 | `mcp_daemon_guard.py:126` | `mark_sanctioned_daemon()` requires the claiming stack frame's resolved absolute path to be the canonical `mcp_server.py` / `gitea_mcp_server.py` next to the guard module; basename spoofing is rejected. | Entrypoint-path identity still exists on a remote host, but it authenticates the *deployment*, not the *caller*. It must be kept and demoted from "authorizes mutations" to "authorizes the process". | needs a seam | #934 |
 | P10 | `gitea_config.py:1233` | The client-config generator emits `"GITEA_CLIENT_MANAGED": "1"` into each generated MCP client entry, alongside `GITEA_MCP_CONFIG` / `GITEA_MCP_PROFILE`. | A remote endpoint is addressed by URL and credential, not by a spawn command with an env block. This generator produces the wrong artifact entirely. | needs a replacement | #938 |
 | P11 | `mcp_namespace_health.py:232` | Namespace health classifies a namespace as `client_managed` or `manual_launch` from the reported env summary. | During dual-run, local and remote namespaces coexist and must both be classifiable; a two-valued local/manual axis cannot express "remote endpoint, authenticated session". | needs a replacement | #939 |
 | P12 | `gitea_mcp_server.py:18161` | The diagnostics payload reports `server_provenance` as exactly `"client_managed"` or `"manual_launch"`. | This is the field a cutover operator reads to confirm which deployment served a call. It must gain a remote value before dual-run parity can be validated. | needs a replacement | #939 |
 ## 3. Role binding
 Role separation is currently enforced by *which process a call reaches*. The process is pinned
 to one role for its lifetime by an environment variable.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | R1 | `gitea_config.py:54` | `ENV_PROFILE = "GITEA_MCP_PROFILE"` is the single source of the active profile, read from the process environment. | One shared process serves several principals; a process-wide profile cannot answer "who is calling now". This is the root of the coupling. | needs a replacement | #932 |
 | R2 | `review_workflow_load.py:95` | Reads `GITEA_MCP_PROFILE` directly to decide the reviewer workflow binding. | Reads the deployment's profile, not the caller's, silently granting or denying the wrong role. | needs a replacement | #932 |
 | R3 | `mcp_discoverability.py:152` | Reads `GITEA_MCP_PROFILE` to describe the namespace to the client. | Correct logic, wrong input source; it needs the request principal injected. | needs a seam | #932 |
 | R4 | `webui/deployment_boundary.py:115` | Reads `GITEA_MCP_PROFILE` to classify the deployment boundary for the console. | Same as R3. | needs a seam | #932 |
 | R5 | `gitea_mcp_server.py:21106` | Remediation text instructs the operator to "Relaunch the server with `GITEA_MCP_PROFILE` set to a profile that has the required permission". | Relaunching a shared remote endpoint to change one caller's role is not a valid instruction; it would re-role every other session. | needs a replacement | #932 |
 | R6 | `native_mcp_preference.py:93` | Detects shell commands that override `GITEA_MCP_PROFILE` away from the session (`native_mcp_preference.py:223`) and flags them as CLI auth divergence. | The divergence check is genuinely useful and survives, but its notion of "the session's profile" must come from the request principal. | needs a seam | #932 |
 | R7 | `gitea_mcp_server.py:20671` | Recovers a peer server's role by regexing `GITEA_MCP_PROFILE=` out of that process's environment. | Depends on P4/P8 process-table access; role discovery by peer-env scraping has no remote analogue. | cannot be remote | #932 |
 ## 4. Credentials
 Every token resolves, directly or indirectly, from one human's macOS keychain.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | C1 | `gitea_config.py:956` | `_keychain_token()` shells `security find-generic-password -s <item> -w`. | `security(1)` is a macOS binary reading the calling user's login keychain. It does not exist on a Linux host and would be the wrong identity even on a shared Mac. | cannot be remote | #933 |
 | C2 | `gitea_config.py:974` | `resolve_token(profile, keychain_lookup=_keychain_token)` dispatches on `auth.type` of `env` or `keychain`, defaulting the lookup to C1. | The injectable `keychain_lookup` parameter is the existing seam; a remote credential provider plugs in here without changing the dispatch. | needs a seam | #933 |
 | C3 | `gitea_config.py:1015` | `keychain_auth(item_id)` constructs the `{"type": "keychain", "id": ...}` reference stored in profiles. | The reference type itself encodes "macOS keychain" into persisted config. A remote provider needs a new auth reference type, not a new value of this one. | needs a replacement | #933 |
 | C4 | `mcp_daemon_guard.py:440` | `assert_keychain_access_allowed()` fails closed for git-credential keychain fill outside a sanctioned daemon, with an operator opt-out env var. | The gate protects a mechanism that will not exist remotely. Its replacement must gate the *credential provider* call, not the keychain call, or the protection silently lapses. | needs a replacement | #933 |
 | C5 | `sentry_incident_bridge.py:190` | `resolve_token(env)` resolves the Sentry token from an injected env mapping with no keychain path. | Already host-neutral; it is the shape the Gitea credential path should converge on. | portable as written | #933 |
 | C6 | `gitea_mcp_server.py:18469` | The profile-audit tool calls `gitea_config.resolve_token(p)` for every configured profile to report "credentials present" without networking. | On a remote host this would materialize every principal's credential inside one process — an audit surface that becomes a credential-aggregation risk. | needs a seam | #933 |
 ## 5. Runtime freshness
 The mutation gate is defined as "the commit this process started at matches the checkout on
 this disk, and both match live master". Two of those three terms are local-disk facts.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | F1 | `master_parity_gate.py:168` | `capture_startup_parity(root)` reads git `HEAD` from the server's own root once at startup and returns it as the baseline. | A remote host carries a deployed artifact, not the operator's checkout. Its `HEAD` says nothing about the operator's working tree, which is the thing the gate exists to protect. | cannot be remote | #935 |
 | F2 | `master_parity_gate.py:255` | `mutation_safe = determinable and in_parity and live_known and not live_stale` — a conjunction of two local-HEAD comparisons and one live-remote comparison. | Two of the three conjuncts lose meaning, so the whole verdict does. A remote deployment needs a redefined, testable freshness predicate rather than this one relocated. | needs a replacement | #935 |
 | F3 | `master_parity_gate.py:164` | The live-remote head is probed and cached per `(root, remote, branch)`, keyed on the local root. | The live-remote probe is the one conjunct that survives; it needs a key that is not the operator's filesystem path. | needs a seam | #935 |
 | F4 | `gitea_mcp_server.py:18262` | `gitea_assess_master_parity` publishes `startup_head` / `local_head` / `live_remote_head` / `mutation_safe` as the authoritative mutation-safety verdict. | The tool's contract is consumed by every mutation caller and by the operator; it must keep its shape while its semantics are redefined, or every consumer breaks at once. | needs a replacement | #935 |
 | F5 | `gitea_mcp_server.py:23054` | Falls back to `_process_boot_head_sha` — the commit this process booted at — when the parity payload has no `startup_head`. | Same defect as F1, in a fallback path that is easy to miss when F1 is fixed. | needs a seam | #935 |
 | F6 | `gitea_mcp_server.py:20615` | Staleness is also inferred from `os.path.getmtime()` of `gitea_mcp_server.py` under `PROJECT_ROOT` (`gitea_mcp_server.py:20611`), compared against peer process start times. | File mtime on a deployed artifact tracks the deploy, not the operator's edits, and the peer start times it is compared against come from the unavailable process table (P4). | cannot be remote | #935 |
 ## 6. Local filesystem
 Author and reviewer tools act directly on the operator's checkout.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | L1 | `gitea_mcp_server.py:10122` | `gitea_bootstrap_author_issue_worktree` creates and binds a git worktree on the server's own disk. | The remote host has no operator checkout to add a worktree to. Executing this remotely would act on the wrong disk while reporting success. | cannot be remote | #936 |
 | L2 | `gitea_mcp_server.py:190` | `ACTIVE_WORKTREE_ENV = "GITEA_ACTIVE_WORKTREE"` and `AUTHOR_WORKTREE_ENV` (`gitea_mcp_server.py:191`) carry the active workspace as process-wide environment. | Process-wide workspace state cannot represent per-session workspaces on a shared endpoint. | needs a replacement | #936 |
 | L3 | `gitea_mcp_server.py:9801` | Binding a worktree writes `os.environ["GITEA_AUTHOR_WORKTREE"]` and `os.environ["GITEA_ACTIVE_WORKTREE"]` (`gitea_mcp_server.py:9802`), mutating global process state. | One session's bind would silently retarget every other concurrent session in the same process. This is a correctness bug the moment concurrency is real. | needs a replacement | #936 |
 | L4 | `reviewer_inventory_worktree.py:48` | `_BRANCHES_WORKTREE_RE = re.compile(r"\bbranches/", re.I)` requires review worktree paths to sit under `branches/`. | A path convention on the operator's machine, asserted as a validation rule. It needs to become a property of a declared workspace, not a substring test. | needs a seam | #936 |
 | L5 | `stable_control_runtime.py:54` | `DEV_WORKTREE_SEGMENT = "branches"` classifies a process root as a development worktree by path segment. | Same class of assumption as L4, on the runtime-classification side. | needs a seam | #936 |
 | L6 | `mcp_server.py:42` | `check_conflict_markers()` runs at import and `os.walk`s the install directory for unresolved conflict markers, `sys.exit(1)` on a hit. | On a remote host it scans a deployed artifact, which by construction never has conflict markers — so the guard passes trivially and stops protecting the thing it was written to protect. | needs a replacement | #936 |
 | L7 | `role_session_router.py:487` | `check_mid_merge()` reports infra-stop from `.git/MERGE_HEAD`, `rebase-merge`, `rebase-apply` and a source conflict scan under the server's project root. | Same inversion as L6: it would report the deployment's git state, not the operator's. | needs a replacement | #936 |
 | L8 | `author_issue_bootstrap.py:996` | Enumerates worktrees with `git -C <root> worktree list --porcelain`. | Requires a real local clone with real worktrees; there is nothing equivalent to enumerate remotely. | cannot be remote | #936 |
 | L9 | `mcp_server.py:10` | Redirects `sys.stderr` to the fixed path `/tmp/mcp_server_stderr.log` outside pytest. | A single fixed `/tmp` path is shared by every concurrent server on a host and is not a deployment's logging surface. | needs a replacement | #938 |
 | L10 | `gitea_mcp_server.py:2314` | `ISSUE_LOCK_FILE = "/tmp/gitea_issue_lock.json"` — the legacy single global lock slot. | One global `/tmp` slot per host cannot represent concurrent remote sessions and is world-visible on a shared machine. | needs a replacement | #937 |
 | L11 | `issue_lock_provenance.py:14` | `ISSUE_LOCK_FILE = os.environ.get("GITEA_ISSUE_LOCK_FILE", "/tmp/gitea_issue_lock.json")` keeps the same `/tmp` default in the provenance path. | Same as L10; the env override is a local escape hatch, not a remote design. | needs a replacement | #937 |
 ## 7. Durable state
 Locks, leases, session state, and the control-plane database live in the operator's home
 directory and are keyed on local PIDs.
 | ID | Anchor | Assumes today | Observes remotely | Class | Owner |
 | -- | ------ | ------------- | ----------------- | ----- | ----- |
 | S1 | `issue_lock_store.py:26` | `DEFAULT_LOCK_DIR = ~/.cache/gitea-tools/issue-locks` — per-issue lock files under one user's home. | A shared endpoint has no single operator home; per-user paths make locks invisible across sessions and hosts. | needs a replacement | #937 |
 | S2 | `issue_lock_store.py:83` | `session_pointer_path()` names the session pointer file `session-<os.getpid()>.json`. | Many sessions share one PID on a remote server, so the pointer collapses to a single slot and sessions overwrite each other. | cannot be remote | #937 |
 | S3 | `issue_lock_store.py:98` | `is_process_alive(pid)` decides lock liveness by probing the local process table. | A PID recorded by one host is meaningless on another, and may coincidentally match a live unrelated process. | cannot be remote | #937 |
 | S4 | `issue_lock_store.py:213` | Lock records stamp `session_pid` and `pid` from `os.getpid()`. | The recorded identity no longer distinguishes sessions; ownership checks silently pass for the wrong caller. | needs a replacement | #937 |
 | S5 | `mcp_session_state.py:27` | `DEFAULT_STATE_DIR = ~/.cache/gitea-tools/session-state`, mode `0o700`. | Same home-directory coupling as S1, for review decision locks and workflow proofs. | needs a replacement | #937 |
 | S6 | `mcp_session_state.py:559` | Session bodies stamp `session_pid` and `writer_pid` from `os.getpid()` (`mcp_session_state.py:560`). | Writer attribution collapses across concurrent sessions in one process. | needs a replacement | #937 |
 | S7 | `control_plane_db.py:47` | `DEFAULT_DB_PATH = ~/.cache/gitea-tools/control-plane/control_plane.sqlite3`. | A per-user SQLite file is not reachable by, or safe for, multiple remote sessions or multiple hosts. | needs a replacement | #937 |
 | S8 | `control_plane_db.py:386` | `sqlite3.connect(self.db_path, timeout=30)` — single-writer file locking tuned for one local process. | SQLite's write lock does not extend across hosts and degrades sharply under real concurrency; the store needs a concurrency-safe backend. | needs a replacement | #937 |
 | S9 | `control_plane_db.py:1145` | Lease rows record `owner_pid` defaulting to `os.getpid()` (also `control_plane_db.py:2039`). | PID-keyed lease ownership is unusable across hosts and ambiguous within one shared process. | cannot be remote | #937 |
 | S10 | `mcp_daemon_guard.py:53` | `_DEFAULT_SESSION_STATE_DIR` is pinned once at transport bind so a later `GITEA_MCP_SESSION_STATE_DIR` change cannot manufacture a second authority domain (#695 AC2). | The single-authority-domain invariant is exactly right and must be preserved; only its backing location needs to move. | needs a seam | #937 |
 | S11 | `gitea_mcp_server.py:11875` | Reviewer-lease reclaim reads `owner_pid_alive` from the lease freshness record to decide whether an owner is dead. | Consumes S3/S9; a false "owner alive" or "owner dead" here reclaims or refuses a live lease. This is the highest-consequence consumer of PID liveness. | cannot be remote | #937 |

 ## Notes for downstream children
 - **The three highest-risk entries are P5, F2, and S11.** Each is a guard that does not
  merely stop working remotely — it inverts. P5 turns concurrency into a reported fault,
  F2 returns a verdict computed from terms that no longer mean anything, and S11 reclaims
  or refuses leases on a PID-liveness answer that is wrong rather than unknown. A gate that
  fails open while still reporting green is worse than one that fails to start.
 - **T4, T5, T7, T8, and C5 are the portable core.** They show the target shape: predicates
  over injected inputs, with no reference to the host, the process table, or the operator's
  disk.
 - **The keychain seam already exists** at C2 (`resolve_token`'s injectable `keychain_lookup`).
  #933 should widen that seam rather than introduce a parallel path, and must remember C4 —
  the guard protecting the old mechanism has to be re-pointed, or the protection lapses
  silently when the mechanism is replaced.
 - **`branches/` appears as a validation rule in at least two independent places** (L4, L5).
  Path-substring conventions tend to have more copies than expected; #936 should re-grep
  rather than trust this list to be exhaustive for that specific pattern.

 """Regression: author bootstrap scope reaches workflow_scope_guard (#941).
 PR #926 (#892) made ``bootstrap_permits_control_checkout`` accept
 ``task_scope=author_issue_bootstrap`` and wired that canonical decision into
 the #274 branches-only enforcer and the #604 anti-stomp preflight. A third
 enforcement path was left unwired.
 ``workflow_scope_guard.assess_root_source_mutation`` kept its own copy of the
 clean-root author decision, gated on ``create_issue_bootstrap.is_create_issue_task``
 — a task-name allowlist that never contained ``bootstrap_author_issue_worktree``.
 So the real call path
    gitea_bootstrap_author_issue_worktree
      -> verify_preflight_purity
        -> _enforce_issue_scope_guard
          -> workflow_scope_guard.assess_production_mutation_guards
 raised ProductionGuardError(missing_issue_worktree) before
 ``assess_author_issue_bootstrap`` was ever consulted.
 These tests drive the real enforcer, not the authorization helper in
 isolation. A helper-only test cannot observe this defect: #892's own predicate
 tests all passed while the live bootstrap stayed blocked.

 """Regression: the author bootstrap wrapper's runtime-context helpers (#943).
 ``gitea_bootstrap_author_issue_worktree`` passed three values down to
 ``author_issue_bootstrap.bootstrap_author_issue_worktree``::
    active_identity=_active_username(),
    active_profile=_active_profile_name(),
    owner_session=_current_session_id(),
 None of those three names was ever defined. Commit ``a942afe`` (#850) introduced
 the references and no definition, so every call — dry-run included — raised
 ``NameError: name '_active_username' is not defined`` while evaluating the
 arguments, before the bootstrap service was entered.
 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``, so the guard fix is what exposed this.
 ``test_every_global_referenced_by_the_wrapper_resolves`` is the test that would
 have caught the original defect: it resolves every global name the wrapper's
 body references. Asserting only that the three known helpers now exist would
 not generalise to the next missing reference.

jcwalker3andClaude Opus 5	f49e781102	fix(author bootstrap): restore missing runtime identity and session helpers (Closes #943 ) 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.

jcwalker3andClaude Opus 4.8 (1M context) <[email protected]>	a09c485fc0	fix(scope): wire author bootstrap scope into workflow scope guard (Closes #941 ) PR #926 (#892) taught create_issue_bootstrap.bootstrap_permits_control_checkout to accept task_scope=author_issue_bootstrap and wired that canonical decision into the #274 branches-only enforcer and the #604 anti-stomp preflight. A third enforcement path was left unwired. workflow_scope_guard kept its own copy of the clean-root author decision, gated on create_issue_bootstrap.is_create_issue_task -- a task-name allowlist that never contained bootstrap_author_issue_worktree. The real call path gitea_bootstrap_author_issue_worktree -> verify_preflight_purity -> _enforce_issue_scope_guard -> workflow_scope_guard.assess_production_mutation_guards therefore raised ProductionGuardError(missing_issue_worktree) before assess_author_issue_bootstrap was ever consulted, leaving the #892 deadlock partially present and blocking issue #931. Changes: * workflow_scope_guard.assess_root_source_mutation accepts the server-derived bootstrap_assessment and, for the clean-root author case, consults the canonical bootstrap_permits_control_checkout decision instead of a local task-name allowlist. The create_issue arm is unchanged. * workflow_scope_guard.assess_production_mutation_guards forwards the evidence. * _enforce_issue_scope_guard accepts and threads the same assessment the #274 and #604 guards already consume, so all three judge identical evidence, and waives the pre-ownership issue-lock requirement for the bootstrap task via that same canonical decision rather than a second task-name allowlist. * verify_preflight_purity passes the once-computed assessment at both sites. The waiver cannot widen: the predicate fails closed on missing, malformed, cross-scope, dirty, drifted, or wrongly bound evidence, so ordinary author source and test mutation from the control checkout stays forbidden and the #274/#604/#618/#683 protections are unchanged. Regression: tests/test_issue_941_scope_guard_bootstrap_wiring.py drives the real enforcer rather than the authorization helper in isolation, which is why #892's own predicate tests passed while the live bootstrap stayed blocked.

It enumerates every place gitea_mcp_server.py and its supporting modules depend on being a local, client-spawned, stdio-attached process on the operator's machine. 62 entries across the seven required categories: transport bind, launch provenance, role binding, credentials, runtime freshness, local filesystem, and durable state. Each entry carries a file and line anchor resolving at `7bf4f12584`, states what the code assumes today and what it would observe on a remote host, is classified as portable as written / needs a seam / needs a replacement / cannot be remote, and is assigned to exactly one epic child. Every child from #931 through #939 is named by at least one entry. Summary tables count entries per category, per classification, per category-by-classification, and per child. Documentation only. No server behavior changes.
