A WEDGED host is the design case, not the edge case: it is the situation that produced the ADR (doyle's own endpoint — read-only rc replayed the retained PTY and `rc --take` acquired control, but a direct prompt produced no output for 30+s because the retained harness subtree itself was nonresponsive while the broker correctly preserved and replayed its last PTY state). Any cooperation-dependent step re-imports the exact hang the verb exists to break. Gate: impl — the kill path proves no dependency on session responsiveness; int — a deliberately nonresponsive/wedged hosted harness is still reaped within the bound (broker row gone + subtree gone), asserted against a real broker-hosted session.

Reverses M9's no-manifest-seam stance; no declarative DSL. [OK] REQ-TERM-6 required: [impl, unit, int] stages: -doc +impl +unit +int Thread-spanning digest across session boundaries: a per-endpoint session ledger (`/sessions.log`) appended at first bind and by `api boundary` on `/clear`|`/compact` session rotation, the digest enumerating the last K sessions so its rolling window bridges a boundary, and a distinctive in-timeline boundary marker (DigestEntry::Boundary). The digest follows the live-agent thread, not a single session.

Data model only this milestone; GUI collapse/expand and the echo-reads-digest delta loop are deferred to the surfaces that consume them. [OK] REQ-TERM-ECHO-CLAMP-WINDOW required: [] stages: -doc -impl -unit -int SEED (DAEMON-LIFECYCLE W3 rideout, field-grounded 2026-07-22): the hosted-TUI echo CLAMP WINDOW — a Windows pseudoconsole boots with echo/line input ON (in=0x1f7, measured by the 7.55 instrument @0f74bba) and it is the hosted CHILD that clamps them, so any window in which the TUI has not yet (re-)clamped echoes typed bytes into PTY output SERVER-SIDE with no seam re-enabling anything. FIELD GROUNDING (hertz capture-2 byte timeline, output-only taps): echo onset is NOT resize-instant — first echoed key lands 6003ms after the first resize-associated repaint burst, IMMEDIATELY after a 3225-byte TUI-reinitialization-shaped absolute repaint (no alt-screen/mode CSI anywhere — cursor hide/show + HOME/absolute repaints only); echo CEASES mid-input (isolated c/o/n/f/i, NO g) directly after a 535-byte TUI diff — consistent with a late clamp landing (a WinAPI mode call is invisible to a byte tap). The resize seam itself is measured MODE-PRESERVING (REQ-RESIZE-INPUT-MODE-INTEGRITY rig, four sample points). OPEN AT TRIAGE: (1) whether the clamp is the TUI's own SetConsoleMode or portable-pty/ConPTY-internal; (2) whether spt-core CAN mitigate at all — the daemon structurally cannot read or set the child console's input modes from the master side (platform fact, 7.55), so candidate mitigations are indirect (e.g. hold/queue injected input until first child output after a reinit-shaped burst — evaluate honestly, may be worse than the disease) and the honest outcome may be an OUT-OF-OUR-CODE finding filed upstream (hosted-TUI reinit behavior + Windows boot default); (3) whether the window also explains historical spt-hosted-only echo reports (non-spt sessions bypass the nested ConPTY — KH 7.55 note).

The class presents as resource exhaustion wearing a timing-flake mask: the release-blocking red was spt-daemon::sync `two_tier_sync_lands_and_gate_refuses_server_side` dying 'No space left on device' INSIDE its own leaked-class tmpdir, and the PRIOR red (digest_cross_node brain-IPC deadline elapse) was the SAME root through a timing probe — burns release windows and invites false environmental discharges (deployah self-corrected his own). ROOT IS UNPROVEN AT MINT (investigate, don't assume): tempfile-crate dirs self-clean on Drop, so something defeats Drop — candidates from the incident record: process killed mid-drop (fixture children force-killed while owning the dir), detached/leaked children pinning the dir cwd so removal fails, panic paths that never unwind. Deliverable: name the leaking fixture path(s) with evidence, fix the cleanup (guard/finalizer that survives the kill path, or a fixture-scoped reaper), and prove it with a before/after dir-count on the suite.

NOT a dormancy/liveness-registration decay (that hypothesis is dead) — deterministic at every checkpoint-armed boundary.

Exactly one of {path, command} (both-set refused at registration; neither = no translation binary). The spawn lifecycle + stdin/stdout JSON-lines protocol (Init/Event/Input → key/text/delay_ms/commit) are UNCHANGED — command alters only how the executable+args are located/launched (read_translation_path → read_translation_command).

NOT a race — deterministic at every checkpoint-armed boundary (perri captured-stderr proof: TRANSLATION_FAULT on the F-019 unread daemon-stderr channel).

Defense-in-depth: `apply_staged` REFUSES a staged single-release artifact unless it is platform-stamped for THIS node (an unstamped pre-v0.3.2 single, or a single stamped for another OS, fail-safe refuses — the guard that alone prevents the v0.3.1 brick where a Linux ELF was applied as `spt.exe`).

Lets a harness adapter ship updates from its own GitHub releases with NO signing tooling or plugin coupling (removes the perri file_pull/delegated avenue blockers).

Semantics: no names -> all gh_release-avenue registrations; names validated FAIL-FAST against the registry BEFORE any update starts (a typo must not leave a half-updated set); per-adapter failure ISOLATION (one failure doesn't stop the rest) with a per-adapter summary line; nonzero exit if any failed; local-path/dev registrations SKIP loud (not error).

ROOT (F-025): a second apply on an already-applied staged version reaches the two-phase binary-aside rename and fails os-error-5, reading as a hard failure when the machine is simply up to date. FIX: apply gains the same pure classifier `fetch` got in v0.18.0 (REQ-UPDATE-FETCH-CURRENT-UX) — already-applied → clear message + exit 0, and the flow MUST short-circuit BEFORE the binary-aside rename in that state; mirror the classifier at ALL apply reject/entry sites the way the fetch fix covered its three.

(F-025) [OK] REQ-UPDATE-DEFAULT-COMPOSITE required: [doc, impl, unit, int] stages: +doc +impl +unit +int THE-FORKENING W4 (operator-grilled 2026-07-14): plain `spt update` = `update fetch --apply` THEN `update adapters` (core-first doctrine order); when core is already current the core leg no-ops and ONLY adapters update; `--core-only`/`-c` skips the adapters leg. GROUNDING (operator-corrected, code-confirmed): fetch --apply cycles the BRAIN only — broker + PTYs survive (apply_staged applyhost.rs:303; the restart-required text is a NOTICE, cli.rs:4615, not behavior) — so the composite's invoking process survives by construction and NO re-run machinery is needed; on a broker-side release the existing F-025 notice remains the composite's closing output. Gate: unit — composite sequencing incl. already-current -> adapters-only and --core-only skip; int — composite on a staged release applies core then updates a registered adapter in one invocation; doc — reference + self-update docs present plain `spt update` as the primary form.

[OK] REQ-UPDATE-FETCH-APPLY-FLAG required: [impl, unit] stages: -doc +impl +unit -int `spt update fetch --apply` is the one-shot get-to-latest: fetch, then INSTALL the staged update REGARDLESS of whether the fetch itself staged anything new — so the brittle `fetch && apply` chain (which broke when fetch no-oped / exited nonzero on an already-staged latest, skipping the chained apply) is unnecessary. Composes with REQ-UPDATE-FETCH-CURRENT-UX: the end state is 'installed latest', reached idempotently from new-staged -> apply / already-staged (applied STILL apply / already-applied -> noop+exit0 / genuine error (bad signature, no artifact for platform, true downgrade, network) -> do NOT apply, propagate the error + nonzero.

ROOT: cmd_update_fetch (cli.rs) sets the rollback floor = staged_version, so when the published candidate == the already-staged version, verify_update_set_metadata returns Err(RejectReason::Rollback{current,candidate}) — printed as {reason:?} (Debug) at exit 1, reading as a FAILURE when the update is merely already downloaded and just needs `spt update apply` (this bit the operator: fetch kept 'failing', apply was the missing step). FIX: a PURE classifier (reason, applied, staged) -> {AlreadyStaged (latest downloaded, not yet installed) / AlreadyApplied (up to date) / GenuineError}; already-staged + already-applied print a friendly message and exit 0; genuine rejects use RejectReason's Display (release.rs, not Debug) + exit 1 — applied at ALL THREE fetch reject sites (metadata + artifact-verify + plan-verify).

ROOT (operator-surfaced probing --finish): `update apply --finish` = daemonless swap -> daemon RESTART; the graceful `daemon stop` path (daemon.rs:316-325) raises brain_stop then reaper.reap() KILLS the brain subtree (brain + shellwake watchers + detached Psyches) as one unit — there is NO per-endpoint final commune before the kill. ENDPOINT-SURVIVAL (REQ-UPDATE-FINISH-ENDPOINT-SURVIVAL) then RESPAWNS each orphaned online spt-hosted endpoint, but from its LAST commune (whatever the ongoing per-event echo-commune cadence last saved), NOT an as-of-swap checkpoint — so mid-turn / uncommuned work is lost across the bounce. Today's mitigation is operator discipline: commune-before-swap. FIX (future): the stop/finish path, before reap, drives each LIVE hosted endpoint's final echo-commune (fire_echo final context save) so the respawn resumes from a swap-fresh checkpoint. Composes with ENDPOINT-SURVIVAL (commune -> reap -> respawn) and the W1 echo pipeline (REQ-ECHO-DROP-DIR-RESOLVE / REQ-PSYCHE-STAMP-CLEAR-ANY-SUCCESS). Bounded + loud per endpoint (a commune that hangs must not wedge the stop — timeout then reap anyway, never block the swap).

ROOT: `brain.ready` != subscribers drained; W2's stall-evict (REQ-HAZARD-BROKER-VIEWER-BRAIN-DECOUPLE) only BOUNDS the false-promote window to BRAIN_WRITE_DEADLINE (15s), it does NOT close it — a new brain can signal ready inside that window while the old gen's conn is still wedged, so the apply 'promotes' onto a still-frozen control plane (the 22:47 incident-night false-promote). FIX: the promotion gate (ADR-0018 brain-trial, brainproc.rs) adds an explicit DRAINED precondition — promote only on ready AND old-gen-subscriber-drained (conn closed OR stall-evicted); the drained signal reads broker truth (the W2 stall-evict tally / the old conn's liveness), no brain round-trip. The residual W2 left open, now closed.

ROOT (F-025): `spt update apply` restarts the BRAIN only (ADR-0018 D3-3) — the BROKER process survives and keeps running its pre-apply compiled image, so every broker-side surface of a freshly-applied release (the F015B live-apply matcher, dispatch inject legs, etc.) is silently dormant until a full daemon bounce, with nothing in the CLI revealing the split. FIX: the running broker SELF-REPORTS its compiled image version over IPC (a new request KIND answered by the live broker process from its own compiled build constant) — HARD CONSTRAINT: the version comes FROM the running broker process, NEVER inferred from disk bytes, install manifest, or file timestamps, since the disk is exactly the half that is already ahead; a version-surface command (`spt version` and/or `spt daemon status`) prints the running-broker version beside the on-disk/product version and flags a mismatch. Keeps read-side truth independent of write-side claims (the field lesson from F015B). (F-025) AMENDED 2026-07-27 (FIELD-TRUTH W1 roll-in, operator-directed): (1) `spt daemon status` MUST also divulge the COORDINATOR (brain) image version — the process that executes daemon-coordinated features and the most relevant running version to a status reader; same HARD CONSTRAINT: sourced from the RUNNING brain process (self-report over the broker↔brain channel or equivalent live query), never inferred from disk. (2) The stale-daemon warning RE-KEYS to the coordinator image vs installed: it renders ONLY when the COORDINATOR is outdated — post-apply the brain restarts onto the new bytes while the broker legitimately stays old (ADR-0018 D3-3), so the broker-keyed warning fired exactly backwards on a healthy freshly-updated node. (3) The remedy line recommends solely `spt daemon refresh` (in-place coordinator cycle; hosted terminals and the net layer keep running), never `daemon stop` + `daemon start`; a broker-breaking release still forces its full bounce through the update machinery, not through status advice. (4) The broker image line stays, informational only — no warning, no remedy text. Coordinator-version query unanswered (older daemon) renders not-reported without the warning.

ROOT (2026-07-09 field freeze, `spt update fetch --apply` v0.30.0->v0.30.2 froze all 7 live PTYs ~30s then rolled back): the promote gate (run_trial, brainproc.rs:657-661) needs BOTH `ready_generation==gen` AND `old_gen_drained()`; `old_gen_drained()` = `!any_local_controller_wedged()` (brainproc.rs:534) is a PURE READ of `write_blocked_since` (broker.rs:2703) — it never DRIVES the evict. The evict (`stall_evict_controller`, broker.rs:1039, same 15s `brain_write_deadline` the wedge-read uses) only runs via `reap_dead_controller` (broker.rs:967, severed->drop ELSE stall-evict) inside the KIND_SESSIONS snapshot closure (broker.rs:2879). During the isolated brain-trial window NOTHING polls KIND_SESSIONS: the old brain was hard-killed (`child.kill()`, brainproc.rs:851) so its local controller conn black-holes (live PTYs keep writing to a dead Windows named pipe -> writer BLOCKS, never EOFs) -> `write_blocked_since=Some` -> wedged=true for the full 30s -> gate false -> `WindowElapsedAlive` -> kill+rollback. The candidate DID reach ready (write_ready, brainproc.rs:211, runs before the loop; the v53 log's NET_FAMILY_GATE/PAIR_MEET_UP prove the loop was entered) — so `BRAIN_TRIAL_TIMEOUT: candidate alive but never ready` is the MISLEADING ready-stamped-but-never-DRAINED case, NOT a resume_sessions hang. SECOND LEG (recovery): post-rollback the gen-2 brain's KIND_SESSIONS poll finally reaps -> `BRAIN_SUBSCRIBER_STALL_EVICT:1` fires >15s late -> a session stayed black-holed through recovery -> continued freeze. ONE root, BOTH legs. FIX (BRAIN-SIDE, self-applying — doyle ruled brain-side to AVOID a broker-side coordinated-restart flag): the boot/trial heartbeat loop (brainproc.rs run_brain, currently only `net_status` at :244) also issues `Brain::sessions()` (KIND_SESSIONS, brain.rs:1397 — already exists) every heartbeat, driving the LIVE older broker's ALREADY-SHIPPED reap (>=v0.29.0 LIFECYCLE-TRUTH; the field-stuck broker is v0.30.0 so it HAS it). The old-gen wedged conn is stall-evicted ~15s < the 30s window -> `old_gen_drained()` flips true -> PROMOTE; the same poll on the rollback/recovery brain reaps promptly -> no >15s black-hole -> kills the STALL_EVICT recovery leg. Drive it on the FIRST heartbeat (no one-tick wait) and on BOTH the trial candidate AND the recovery brain (one loop covers both). SELF-APPLIES because it drives the current broker's existing reap verb — v54's brain fixes the v0.30.0->v54 update with NO coordinated broker restart. Forward-compat: brokers rollback); (2) a deliberately-failing trial auto-rolls-back AND the restored brain re-drives EVERY session with NO BRAIN_SUBSCRIBER_STALL_EVICT. [OK] REQ-VIEWER-SKIP-TO-LIVE-ON-EVICT required: [doc, impl, unit, int] stages: +doc +impl +unit +int A `rc --view` VIEWER that overflows its broker subscription queue and is EVICTED (OutputLog::append try_send Full → viewers.remove, REQ-HAZARD-VIEWER-ISOLATION session-protection) must SKIP TO LIVE, not die silently. ROOT (v0.13.0, b4 JIT item 2 = p0_paste + post-b4 a_journaled-Linux, ONE root): serve_attach forwards each frame (read_event→b64decode→re-encode AttachRecord→net_stream_send) SLOWER than the drain fans out under flood → its VIEWER_CHANNEL_DEPTH(256) channel overflows → the drain evicts (viewers.remove drops the ViewerSink → drops tx → viewer_writer's rx.recv() Err → the writer returns WRITING NOTHING) → serve_attach's brain.read_event() just STOPS getting Output (no EOF, no error) → serve_attach blocks forever → the operator receives nothing (attach_received_output=FALSE). Eviction-of-a-hopelessly-behind-viewer is CORRECT session-protection (keep it); SILENT+PERMANENT eviction is the bug. VIEWER-only → B2-SAFE (a viewer never advances delivered_through / is not authoritative / exposes no resume cursor). FIX (doyle-gated, skip-to-live = tail -f reconnect): (1) explicit broker→viewer EVICTION SIGNAL (KIND_VIEWER_EVICTED, written in the viewer_writer thread OFF the log lock, DISTINCT from session-exit EOF so serve must NOT tear down on it); (2) serve_attach re-subscribes from the CURRENT ring floor (skip-to-live, replays nothing, sees the next live burst) — resetting the cold serve-brain's next_seq so the post-eviction forward-jump replay is accepted (the legacy reject-gap path, brain.rs:618-626, would otherwise FATAL the forward jump); (3) HARD constraint NO evict→resubscribe busy-loop: serve_attach rate-limits re-subscribes (RESUBSCRIBE_INTERVAL) so under max-flood the operator sees intermittent LIVE bursts, never a CPU spin. (v0.13.0) [OK] REQ-WAKE-RESUME-LEG required: [impl, unit, int] stages: -doc +impl +unit +int A-2 (REMOTE-TRUTH triage §A-2 + ADR-0033): the daemon reconcile gains a WAKE-RESUME LEG — an endpoint whose rest INTENT is Active but whose harness session is COLD (status != online) is resumed by the daemon via the adapter's [session.resume] template using the LAST LEDGER session id, so a bare `spt wake ` on a suspended live agent actually brings it back (today: reconcile_once start-arm hosts ONLY status==online (livehost.rs:199), so a woken-but-unbound endpoint is skipped forever — neither status reaches online nor does reconcile re-host). This is the ADR-0033 LIFT: the thin `spt wake` edge writes rest intent, the DAEMON does the work. Mirrors shellwake::resolve_wake (read rest state, live-pid double-launch guard, launch, NEVER flip status — the harness self-binds → online). The leg reads the recorded adapter (D-2, REQ-SESSION-ADAPTER-RECORDED); an UNREGISTERED recorded adapter is the Q5 daemon-variant refuse: do NOT spawn, record a LOUD host_error report (F-1 naming the adapter + `spt adapter add`), never silent, never fallback-spawn on a different adapter. BINDS: (1) status=online is set ONLY by a real bind — the resume leg NEVER stamps it (CONTEXT liveness truth; the A-1 effective-state derivation depends on this staying honest). (2) host_error is a REPORT of the most recent host-level failure, NEVER a liveness input — neither liveness nor advertised_status reads it (host_error + online still derives Active); cleared on a successful host/bind; the existing silent `continue` on a deregistered online adapter (livehost.rs:205) folds into the same field. (3) the resume-pid guard marker is CUSTODY-ONLY (F-030 nested-record discipline) — never a liveness input. cold-with-no-ledger-row degrades benign (loud-logged skip, no crash, today's behavior). Single-node; C-2 picker Wake-now unblocks after. --wait is a SEPARATE rider (REQ-WAKE-WAIT). [OK] REQ-WAKE-WAIT required: [] stages: -doc -impl -unit -int A-2 rider (REMOTE-TRUTH triage §A-2): `spt endpoint wake --wait` blocks on the REAL bind (status reaches online) after the daemon wake-resume lift (REQ-WAKE-RESUME-LEG), instead of the DEFAULT accepted-not-bound print (thin edge writes intent, daemon lifts async — ADR-0033). Reuses the F-027 bind-await machinery if/when it lands, else a bounded poll on status==online with a plain-language timeout (no core lingo, F-1). Default wake is UNCHANGED (accepted-not-bound truth). Separate chunk from the core leg (doyle A-2 ruling: C-2 needs the core leg, not --wait); F-027 bind-await stays design-only until this activates. [OK] REQ-WAN-SEND-DELIVERY required: [impl, unit, int] stages: -doc +impl +unit +int Bug #9/#10: cross-node spt send reports SENT(WAN) but does not deliver, even on stable-IP pairs. Real root: spt send resolves the dial with id-only addr_for_node_hex (endpoint.rs:538) which forces a fresh iroh discovery round-trip every send, while the gossip pump uses cached direct addresses (dial_seeded/PeerAddrStore) so gossip stays green but send rides a marginal discovery path that cannot carry the fire-and-forget payload; the handshake completes so SENT(WAN) prints falsely. Fix: (1) route the WAN dial through the pump seeded-direct-address resolution (PeerAddrStore first, id-only fallback); (2) receiver writes its WanOutcome back so the sender confirms delivery under the QUIC deadline and only reports SENT on confirmed delivery, honest failure otherwise. Access-gate/perch/spool all verified correct (ruled out). See docs/NEXT-MILESTONE-BUG-TRIAGE.md #9-10. [OK] REQ-WAN-SPT-HOSTED-DELIVERY required: [impl, unit, int] stages: -doc +impl +unit +int A WAN-ARRIVED `spt send` is DELIVERED to an spt-hosted endpoint (broker holds its PTY, NO api-listen relay), not spooled-forever. Today receive_wan (spt-daemon/wan.rs:271-276) tries deliver_tcp (the harness-hosted relay leg) then falls to spool — it has NO spt-hosted broker-inject leg, which exists ONLY in local cmd_send (REQ-SEND-SPT-HOSTED, Brain::inject_endpoint → KIND_ENDPOINT_INPUT → broker dispatch_endpoint_input → translation-binary idle-inject). So a WAN arrival to an idle spt-hosted perch with a live translation binary ALWAYS sleeps in spool until an adapter hook polls (F-023: perch verifiably idle 7min, binary healthy, zero injection). FIX: factor cmd_send's spt-hosted delivery leg into a SHARED fn; receive_wan calls it after the replay-check (wan_seen_at) + restamp (restamp_wan_user_msg), BEFORE the spool fallback. Claim discipline UNCHANGED: inject delivered=true → wan_mark_seen_at then return the existing 'delivered' wire token (no wire change); delivered=false → the existing spool-with-claim transaction. v0.14.3 LAW: the shared leg is translation-binary-ONLY, NO raw-PTY fallback — a no-binary arrival SPOOLS LOUD, never writes the PTY. (F-023, BUILD-F023-WANIDLE) [OK] REQ-WHOAMI-1 required: [doc, impl, unit] stages: +doc +impl +unit -int The `endpoint list` SELF pin carries the Self endpoint's authored `endpoint description` (info::read_info(...).resources) when present, inline after the liveness state; whoami stays a top-level hot-path verb (parse unchanged, REQ-MSG-9) and renders the same description-carrying SELF pin. HISTORY: originally minted whoami as a thin ALIAS of `spt endpoint list` — that alias premise is SUPERSEDED by REQ-WHOAMI-IDENTITY-ONLY (PROJECT-INDEX W1, 2026-07-15): the alias inherited the list's O(perches x branches) git fanout onto hook paths (the 2026-07-15 message-delivery incident), so whoami is now identity-only over the shared render_self_pin. The pin render + parse evidence here stands; the full-roster surface lives solely on `endpoint list`. [OK] REQ-WHOAMI-EXPLICIT-SID-REFUSAL required: [] stages: -doc -impl -unit -int RULED DESIGN, delivery unowned (doyle 2026-07-26): when a caller hands identity resolution an EXPLICIT non-empty $OWL_SESSION_ID that resolves to NO perch, core must REFUSE identity (unresolved, exit 1, loud distinct diagnostic) rather than fall through to an ambient/inherited one — today `detect_self_id` (roster.rs, legs a→b→b2→c) treats sid-UNMATCHED identically to sid-ABSENT, so the fallback chain re-adopts precisely the identity a sharper claim just failed to prove. MEASURED (perri, this node, 2026-07-26, three read-only whoami calls from a genuine descendant of the perri host process): (1) all SPT_*/OWL_* scrubbed → id null, exit 1 — ancestry resolved nothing (caveat honored from the probe: the perch's recorded pid was not in the caller's chain, so this run refutes lineage-as-the-mechanism for probe v1 without disproving a lineage path in general); (2) inherited SPT_ENDPOINT_ID=perri + explicit OWL_SESSION_ID matching no perch → perri, exit 0 — the mismatch datum was IN HAND (core had already scanned and failed to match the explicit sid) and the ambient id won anyway; (3) real OWL_SESSION_ID with endpoint id scrubbed → correct self — the healthy path any fix must leave untouched. SCOPE OF THE REFUSAL, ruled: only sid-PRESENT-AND-UNMATCHED poisons the fallback, and it poisons ALL weaker legs (b SPT_AGENT_ID, b2 SPT_ENDPOINT_ID, c pid-ancestry) — an explicit failed claim outranks every ambient claim below it; sid-ABSENT/empty keeps today's full chain unchanged, because the leg-b2 field root (live-repro'd 2026-07-10: the adapter surfaces OWL_SESSION_ID to the session shell as an UNEXPORTED var, so the child process legitimately carries endpoint id without sid) is exactly the flow the guard must not break — that flow is sid-absent, never sid-mismatched. WHY CORE AND NOT ONLY THE ADAPTER: the measured entry path is closed adapter-side (perri's REQ-HAZARD-INHERITED-IDENTITY-ADOPTION @ their a7558aa + claude-spt KNOWN-HAZARDS 7.4, shipped: whoami child calls scrub SPT_ENDPOINT_ID/SPT_AGENT_ID; rig discipline now detached AND env-scrubbed — the scrub is the operative half), but the inconsistency being fixed is CORE'S: the adapter fastpath's verified_env_id REFUSES an inherited SPT_ENDPOINT_ID on carrier-proof mismatch (carrier sid != payload sid) and core's fallback then RE-GRANTS what that layer just refused — one layer's refusal must not be another layer's grant, and every other harness/adapter gets the defense only if core holds it. SEVERITY UPGRADE recorded at mint: unlike the KH 7.1–7.3 shapes (lost reads), this adoption was WRITE-CAPABLE in the field — the adopting descendant re-pointed the ANCESTOR's session pin, so the ancestor went dark while the descendant looked healthy (perri's own pin, probe v1). KIN, same review same milestone: leg (b) SPT_AGENT_ID returns UNCONDITIONALLY today — not even perch-checked, weaker than leg b2's bound-perch gate; align it when this lands. MEASURED on the live node, not just code-read (perri, same probe run, reported 2026-07-26): SPT_AGENT_ID=nobody-xyz with a bogus OWL_SESSION_ID returned {'id':'nobody-xyz','ready':false,'alive':true,'unbound':false}, exit 0 — a phantom identity for an endpoint that does not exist, beating both the sid leg and ancestry; the returned shape has no state key and ready:false but a populated id, and the adapter parser takes .id first, so a whoami-trusting adapter writes state under the phantom — the same write-capable class as the inherited-adoption case, sourced from a made-up name instead of a real ancestor. perri's adapter scrub covers SPT_AGENT_ID as well as SPT_ENDPOINT_ID for exactly this reason. POSTURE UNCHANGED: whoami legs remain from-label/routing only, never authentication (KH 7.3/7.5, F-024 stays parked) — refusal tightens label discipline, it promotes nothing to auth. Gate at activation: unit — sid-unmatched + ambient endpoint id present → refusal with the distinct diagnostic (probe shape 2 goes loud); sid-absent + ambient endpoint id on a bound perch → still resolves (leg-b2 field root preserved); sid-matched → unchanged (probe shape 3). [OK] REQ-WHOAMI-IDENTITY-ONLY required: [doc, impl, unit, int] stages: +doc +impl +unit +int PROJECT-INDEX W1 (F-040, perri filing claude-spt docs/SPT-CORE-FINDINGS.md @d775b38; correctness-critical opener — the 2026-07-15 message-bodies incident root): a core IDENTITY-ONLY resolution — session -> endpoint|null — that touches NO list/registry/project/git/network path, and `spt whoami` DE-ALIASED from cmd_endpoint_list (cli.rs ~6609 aliases the full list = 100+ git children under hook deadlines). endpoint-info is DISQUALIFIED as the carrier (runs latest_project_ref). Adapters/hooks get a bounded-time identity verb; the harness-hosted adapter fallback stays deadline-vulnerable until this ships. Gate: impl — the resolver + whoami de-alias; unit — resolver returns endpoint|null with zero project derivation (assert no git spawn seam); int — whoami on a multi-perch home answers fast-path without touching context branches; doc — harness-contract api.md names the identity verb + its no-derivation bound. Kin REQ-PROJECT-INDEX-READER-CUTOVER (list-shaped verbs), REQ-WHOAMI-1, docs/PROJECT-INDEX-TRIAGE.md. [OK] REQ-WORKER-LIST-VISIBILITY required: [impl, int] stages: -doc +impl -unit +int V-1 (WORKER-TRUTH triage, operator rider): worker perches leave the DEFAULT `spt endpoint list` view — they are process-local machinery, not subnet citizens; leaked-or-live worker rows rendering as permanent OFFLINE endpoints is the operator-visible symptom root. A dedicated flag (--workers) reveals them (one command + flag per the --all/--detail precedent, NOT a separate list-working command — sister divergence deliberate). Applies to the human render, --json (additive default-absent filter), and the registry/projection legs; verify-and-stop any worker gossip into the subnet registry as peer endpoints. [OK] REQ-WORKER-MINTED-NAME required: [doc, impl, unit, int] stages: +doc +impl +unit +int N-1 (WORKER-TRUTH triage, operator rider): worker perch identity is CORE-MINTED and parent-derived — `{parent}-w{N}` with a per-parent counter at registration (sister shape: claude_skill_owl hook_subagent_start.rs) — never the adapter-presented agent id (CC Task ids render as random-named rows). worker-start mints + echoes the id (WORKER_STARTED:{parent}-w{N}); the adapter's agent_id/agent_type ride the record as correlation METADATA, not identity. Verb-shape contract change — freeze with W-2 in ONE coordination with perri. [OK] REQ-WORKER-PICKER-EXCLUDED required: [impl, unit] stages: -doc +impl +unit -int V-2 (WORKER-TRUTH triage, operator rider): non-drivable endpoint classes never render as `spt endpoint run` picker rows — a worker perch cannot be driven, instantiated, or controlled; offering it is a lie the picker then fails on. Filter endpoint_type worker (and the psyche class if it ever surfaces — same non-drivable family) at every picker source leg, extend-not-multiply for future non-drivable classes. [OK] REQ-WORKER-REAP required: [impl, unit, int] stages: -doc +impl +unit +int W-3 (WORKER-TRUTH triage): worker records must not persist indefinitely past their useful life — 6 dead-pid workers leaked OFFLINE on flynn (kill-paths where SubagentStop never fires: parent killed, abort, timeout). The stored rec.pid is the ephemeral worker-start hook process (dead by design — the REQ-HAZARD-DEAD-REC-PID class; NEVER an alive-gate signal). Honest reap signals: (a) parent-session lifecycle — reap the parent's soft-stopped + orphaned workers at parent session-end/boundary and on parent-death detection (a worker cannot outlive its parent's live session); (b) a generous TTL floor since `created` as belt-and-braces. Soft-stop preservation semantics (REQ-HAZARD-SOFT-CLEANUP: results drain before reap) stay honored — reap after drain-or-expiry, never mid-flight hard-delete (cascade-wipe guard rationale stands). Sister shape: claude_skill_owl doctor D-21 orphan-worker GC. [OK] REQ-WORKER-SID-SYMMETRIC-AUTH required: [doc, impl, unit, int] stages: +doc +impl +unit +int W-2 (WORKER-TRUTH triage, operator-ruled 2026-07-06): worker verbs go sid-symmetric with every sibling id-scoped verb — worker-start mints NO token and worker-stop takes NONE (token custody is undue adapter burden, ruling via perri). Registration STORES the sid it authenticated (the parent's sid at start; today cmd_worker_start hardcodes session_id="" — worker.rs:44 — so a sid-authed stop compares against empty and refuses 100%). Stop accepts the parent's CURRENT sid OR the stored registration sid (a /clear between start and stop rotates the parent's sid; either rotation endpoint is honest custody — the REQ-PSYCHE-SID-CUSTODY rotation reasoning). Under the ruling the field adapter's existing emission (worker-stop --session-id ) becomes contract-correct as-is. Publish the frozen verb shape to the docs-site with the landing wave (perri blind-builds from published docs). [OK] REQ-XTASK-SPT-BIN-TARGET-DIR required: [impl, unit] stages: -doc +impl +unit -int #13 (F026 micro, tooling): xtask `spt_bin()` (crates/xtask/src/main.rs) BUILDS `spt` via cargo (which honors CARGO_TARGET_DIR) but returns a HARDCODED `/target/debug/spt` path — so under a redirected target dir (CI / isolated-gate rigs that set CARGO_TARGET_DIR to a throwaway) the binary lands in `$CARGO_TARGET_DIR/debug` while xtask looks in `/target/debug` -> NotFound -> `xtask check` (docs-drift gate) spuriously fails. Workaround was running `xtask check` with CARGO_TARGET_DIR unset. FIX: a pure `target_debug_dir(root, CARGO_TARGET_DIR)` seam mirroring cargo's resolution — absolute override as-is, relative resolved against `root` (the dir cargo is invoked in), default `/target` — join `debug`; `spt_bin` returns from it.
