State facts from the transcript only — no speculation, no preamble, no closing remarks.\nDo NOT compile a roster of peer agents: name another agent only where the transcript shows a direct exchange with it. Machine/host/node names (window titles like `agent @ HOST`, CI runner boxes, `spt endpoint list` node headers) are computers an agent runs ON, not agents — never list a host as a peer or an agent.\nSlice the delta so spt routes each part to the right durable tier: put everything specific to THIS project (its task, files, and decisions) inside <project-context>…</project-context>, and any cross-project, role, or standing-identity context inside <live-context>…</live-context>. Untagged text defaults to the live tier, so tag project-specific detail to keep it out of the durable identity. Output the sliced delta and nothing else.\n\n---- transcript tail ----\n{\"parentUuid\":\"929775a3-2dee-4b90-906c-ed35f8752ec8\",\"isSidechain\":false,\"promptId\":\"82555bac-f2ea-4a7e-b5de-b705e8e8591e\",\"type\":\"user\",\"message\":{\"role\":\"user\",\"content\":[{\"tool_use_id\":\"toolu_01RMFEii3N1r8qfA9AdYyWB9\",\"type\":\"tool_result\",\"content\":\"The file C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\\\\W3-239-BOUNDARY-DESIGN.md has been updated successfully.

Path (lane worktree .worktrees/ir57):\\n  W3-239-BOUNDARY-DESIGN.md\\nGroundwork with the raw measurements beside it: W3-239-GROUNDWORK.md\\n\\nBoth of your asks are answered in it, and both changed the proposal rather than being appended to it.\\n\\n1. THE MODULE%s STANDING REFUSAL (iolog.rs:74-80, \\\"a second byte-cap knob would be a second place to be wrong\\\"). You were right that my floor was its near neighbour — it WAS the refused shape: a second declared retention number, hand-picked, expressing a bound the module already derives. The 64-row floor is WITHDRAWN, and §4.1 records that it was proposed and why it fell rather than quietly deleting it.\\n   What replaced it adds NO knob at all. C2 is now stated as an ORDERING: the trim evicts the oldest NON-boundary row first, and evicts a boundary only when no non-boundary row remains. IO_LOG_MAX_ROWS and IO_LOG_TRIM_SLACK stay the only retention numbers; the change is WHICH row the trim picks, never HOW MANY are kept. Three consequences fall out instead of being declared: the pathological all-boundary case is bounded by the SAME cap (1000, not a new limit that has to be right); the derived byte ceiling is untouched and can only shrink, since a boundary payload is \\\"\\\" where the derivation assumed the 16KB class; and the module%s \\\"FLOOR on retention, not a ceiling\\\" framing survives verbatim. So the distinction I claim is one of KIND — the refusal is against a second CAP, this is an ORDERING WITHIN the existing cap. §10 names that as the argument I most want attacked, because a rule that is NEARLY a knob is worse than one that plainly is.\\n\\n2. THE RATE, measured (§4.2), meter stated before the numbers: first-record timestamp of every harness transcript under the spt-core project dir, 2678 of 2783 files parsed (105 empty or headerless), cross-checked against mtimes independently — same day-shape, peak hour within one count, so it is not an artifact of either clock.\\n   PEAK DAY 723 sessions, PEAK HOUR 65 (next: 58, 53, 50, 49), across 9 active days — a heavy-use corpus, not an idle one.\\n   Both error directions declared: it OVER-counts per endpoint (65/hr is project-wide across every agent in this cwd, while the io log is per-endpoint) and UNDER-counts boundaries (one that does not rotate a session id leaves no transcript).\\n   What it buys: even taking the whole project-wide 65/hr as if ONE endpoint carried it, boundaries are ≲12% of the rows in the 1000-row / ~1.85h window, low single-digit percent realistically. So volume is NOT the problem and C3%s separate retention is not needed to make room — that argument for C3 is now dead, measured.\\n   And the number sharpens the real risk rather than dissolving it: under C1 a boot row is evicted after ~1000 rows of agent output — about two hours of busy work at the W2 worst case — displaced by exactly the row class the ruling says must not displace it. At ANY cap the last thing you want evicted is the rarest row, which is what an ordering fixes and a bigger cap does not.\\n\\nAlso in the doc, since you asked me to carry it as grounding: §1 corroborates the ruling%s own premise at the implementation (drivehub write_slot/take_slot, the two hub tests) rather than at the doc it cites, plus the observation that boot is worse than the ruling%s general case — it fires at perch bind before any shell can attach, so on the ephemeral carrier boot is unobservable close to always, not merely lossy under load.\\n\\nThree decisions requested (§10): C2 over C1/C3; the kind-vs-degree distinction in §4.1; and no new poll verb (which follows from C2 and falls if you gate C3 instead).' \\\"'\\\" \\\"'\\\" \\\"'\\\" \\\"'\\\" \\\"'\\\" | spt send doyle\",\"description\":\"Send W3 design doc path to doyle\"},\"caller\":{\"type\":\"direct\"}}],\"stop_reason\":\"tool_use\",\"stop_sequence\":null,\"stop_details\":null,\"usage\":{\"input_tokens\":2,\"cache_creation_input_tokens\":2071,\"cache_read_input_tokens\":202262,\"output_tokens\":1451,\"output_tokens_details\":{\"thinking_tokens\":0},\"server_tool_use\":{\"web_search_requests\":0,\"web_fetch_requests\":0},\"service_tier\":\"standard\",\"cache_creation\":{\"ephemeral_1h_input_tokens\":2071,\"ephemeral_5m_input_tokens\":0},\"inference_geo\":\"not_available\",\"iterations\":[{\"input_tokens\":2,\"output_tokens\":1451,\"cache_read_input_tokens\":202262,\"cache_creation_input_tokens\":2071,\"cache_creation\":{\"ephemeral_5m_input_tokens\":0,\"ephemeral_1h_input_tokens\":2071},\"type\":\"message\"}],\"speed\":\"standard\"},\"diagnostics\":null},\"requestId\":\"req_011CeXC2AaHm2cMLpu7q1P2X\",\"type\":\"assistant\",\"uuid\":\"eb03e261-ccdb-465d-b21b-e647e63b27aa\",\"timestamp\":\"2026-08-29T14:23:37.539Z\",\"effort\":\"high\",\"session_id\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"userType\":\"external\",\"entrypoint\":\"cli\",\"cwd\":\"C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\",\"sessionId\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"version\":\"2.1.251\",\"gitBranch\":\"main\"}\n{\"parentUuid\":\"eb03e261-ccdb-465d-b21b-e647e63b27aa\",\"isSidechain\":false,\"promptId\":\"82555bac-f2ea-4a7e-b5de-b705e8e8591e\",\"type\":\"user\",\"message\":{\"role\":\"user\",\"content\":[{\"tool_use_id\":\"toolu_01CiL8TzbRZ8einciHCekSA9\",\"type\":\"tool_result\",\"content\":\"SENT:doyle\",\"is_error\":false}]},\"uuid\":\"f6988ecc-807e-4483-92c9-fe94738d6610\",\"timestamp\":\"2026-08-29T14:23:38.013Z\",\"toolUseResult\":{\"stdout\":\"SENT:doyle\",\"stderr\":\"\",\"interrupted\":false,\"isImage\":false,\"noOutputExpected\":false},\"sourceToolAssistantUUID\":\"eb03e261-ccdb-465d-b21b-e647e63b27aa\",\"session_id\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"userType\":\"external\",\"entrypoint\":\"cli\",\"cwd\":\"C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\",\"sessionId\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"version\":\"2.1.251\",\"gitBranch\":\"main\"}\n{\"parentUuid\":\"f6988ecc-807e-4483-92c9-fe94738d6610\",\"isSidechain\":false,\"attachment\":{\"type\":\"total_tokens_reminder\",\"text\":\"<total_tokens>14961875 tokens left</total_tokens>\"},\"type\":\"attachment\",\"uuid\":\"fdcf7d3b-5c28-4975-9088-89a117cce295\",\"timestamp\":\"2026-08-29T14:23:38.017Z\",\"session_id\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"userType\":\"external\",\"entrypoint\":\"cli\",\"cwd\":\"C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\",\"sessionId\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"version\":\"2.1.251\",\"gitBranch\":\"main\"}\n{\"parentUuid\":\"fdcf7d3b-5c28-4975-9088-89a117cce295\",\"isSidechain\":false,\"message\":{\"model\":\"claude-opus-5\",\"id\":\"msg_011CeXC3fR9xofwHFa2kHWQg\",\"type\":\"message\",\"role\":\"assistant\",\"content\":[{\"type\":\"text\",\"text\":\"W3 design proposal is with doyle: `.worktrees/ir57/W3-239-BOUNDARY-DESIGN.md` (groundwork beside it).\\n\\nTwo course corrections landed before the draft reached him:\\n\\n**The fork was already ruled.** doyle caught that I hadn't opened `SEMAPHORE-242-GRILL.md` for this member.

C2 is now stated as an ORDERING: the trim evicts the oldest NON-boundary row first, and evicts a boundary only when no non-boundary row remains. IO_LOG_MAX_ROWS and IO_LOG_TRIM_SLACK stay the only retention numbers; the change is WHICH row the trim picks, never HOW MANY are kept. Three consequences fall out instead of being declared: the pathological all-boundary case is bounded by the SAME cap (1000, not a new limit that has to be right); the derived byte ceiling is untouched and can only shrink, since a boundary payload is \\\"\\\" where the derivation assumed the 16KB class; and the module%s \\\"FLOOR on retention, not a ceiling\\\" framing survives verbatim. So the distinction I claim is one of KIND — the refusal is against a second CAP, this is an ORDERING WITHIN the existing cap. §10 names that as the argument I most want attacked, because a rule that is NEARLY a knob is worse than one that plainly is.\\n\\n2. THE RATE, measured (§4.2), meter stated before the numbers: first-record timestamp of every harness transcript under the spt-core project dir, 2678 of 2783 files parsed (105 empty or headerless), cross-checked against mtimes independently — same day-shape, peak hour within one count, so it is not an artifact of either clock.\\n   PEAK DAY 723 sessions, PEAK HOUR 65 (next: 58, 53, 50, 49), across 9 active days — a heavy-use corpus, not an idle one.\\n   Both error directions declared: it OVER-counts per endpoint (65/hr is project-wide across every agent in this cwd, while the io log is per-endpoint) and UNDER-counts boundaries (one that does not rotate a session id leaves no transcript).\\n   What it buys: even taking the whole project-wide 65/hr as if ONE endpoint carried it, boundaries are ≲12% of the rows in the 1000-row / ~1.85h window, low single-digit percent realistically. So volume is NOT the problem and C3%s separate retention is not needed to make room — that argument for C3 is now dead, measured.\\n   And the number sharpens the real risk rather than dissolving it: under C1 a boot row is evicted after ~1000 rows of agent output — about two hours of busy work at the W2 worst case — displaced by exactly the row class the ruling says must not displace it. At ANY cap the last thing you want evicted is the rarest row, which is what an ordering fixes and a bigger cap does not.\\n\\nAlso in the doc, since you asked me to carry it as grounding: §1 corroborates the ruling%s own premise at the implementation (drivehub write_slot/take_slot, the two hub tests) rather than at the doc it cites, plus the observation that boot is worse than the ruling%s general case — it fires at perch bind before any shell can attach, so on the ephemeral carrier boot is unobservable close to always, not merely lossy under load.\\n\\nThree decisions requested (§10): C2 over C1/C3; the kind-vs-degree distinction in §4.1; and no new poll verb (which follows from C2 and falls if you gate C3 instead).' \\\"'\\\" \\\"'\\\" \\\"'\\\" \\\"'\\\" \\\"'\\\" | spt send doyle\",\"description\":\"Send W3 design doc path to doyle\"},\"caller\":{\"type\":\"direct\"}}],\"stop_reason\":\"tool_use\",\"stop_sequence\":null,\"stop_details\":null,\"usage\":{\"input_tokens\":2,\"cache_creation_input_tokens\":2071,\"cache_read_input_tokens\":202262,\"output_tokens\":1451,\"output_tokens_details\":{\"thinking_tokens\":0},\"server_tool_use\":{\"web_search_requests\":0,\"web_fetch_requests\":0},\"service_tier\":\"standard\",\"cache_creation\":{\"ephemeral_1h_input_tokens\":2071,\"ephemeral_5m_input_tokens\":0},\"inference_geo\":\"not_available\",\"iterations\":[{\"input_tokens\":2,\"output_tokens\":1451,\"cache_read_input_tokens\":202262,\"cache_creation_input_tokens\":2071,\"cache_creation\":{\"ephemeral_5m_input_tokens\":0,\"ephemeral_1h_input_tokens\":2071},\"type\":\"message\"}],\"speed\":\"standard\"},\"diagnostics\":null},\"requestId\":\"req_011CeXC2AaHm2cMLpu7q1P2X\",\"type\":\"assistant\",\"uuid\":\"eb03e261-ccdb-465d-b21b-e647e63b27aa\",\"timestamp\":\"2026-08-29T14:23:37.539Z\",\"effort\":\"high\",\"session_id\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"userType\":\"external\",\"entrypoint\":\"cli\",\"cwd\":\"C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\",\"sessionId\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"version\":\"2.1.251\",\"gitBranch\":\"main\"}\n{\"parentUuid\":\"eb03e261-ccdb-465d-b21b-e647e63b27aa\",\"isSidechain\":false,\"promptId\":\"82555bac-f2ea-4a7e-b5de-b705e8e8591e\",\"type\":\"user\",\"message\":{\"role\":\"user\",\"content\":[{\"tool_use_id\":\"toolu_01CiL8TzbRZ8einciHCekSA9\",\"type\":\"tool_result\",\"content\":\"SENT:doyle\",\"is_error\":false}]},\"uuid\":\"f6988ecc-807e-4483-92c9-fe94738d6610\",\"timestamp\":\"2026-08-29T14:23:38.013Z\",\"toolUseResult\":{\"stdout\":\"SENT:doyle\",\"stderr\":\"\",\"interrupted\":false,\"isImage\":false,\"noOutputExpected\":false},\"sourceToolAssistantUUID\":\"eb03e261-ccdb-465d-b21b-e647e63b27aa\",\"session_id\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"userType\":\"external\",\"entrypoint\":\"cli\",\"cwd\":\"C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\",\"sessionId\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"version\":\"2.1.251\",\"gitBranch\":\"main\"}\n{\"parentUuid\":\"f6988ecc-807e-4483-92c9-fe94738d6610\",\"isSidechain\":false,\"attachment\":{\"type\":\"total_tokens_reminder\",\"text\":\"<total_tokens>14961875 tokens left</total_tokens>\"},\"type\":\"attachment\",\"uuid\":\"fdcf7d3b-5c28-4975-9088-89a117cce295\",\"timestamp\":\"2026-08-29T14:23:38.017Z\",\"session_id\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"userType\":\"external\",\"entrypoint\":\"cli\",\"cwd\":\"C:\\\\Users\\\\decid\\\\Documents\\\\projects\\\\spt-core\\\\.worktrees\\\\ir57\",\"sessionId\":\"880d1285-2246-4429-9b5e-eb4331af141f\",\"version\":\"2.1.251\",\"gitBranch\":\"main\"}\n{\"parentUuid\":\"fdcf7d3b-5c28-4975-9088-89a117cce295\",\"isSidechain\":false,\"message\":{\"model\":\"claude-opus-5\",\"id\":\"msg_011CeXC3fR9xofwHFa2kHWQg\",\"type\":\"message\",\"role\":\"assistant\",\"content\":[{\"type\":\"text\",\"text\":\"W3 design proposal is with doyle: `.worktrees/ir57/W3-239-BOUNDARY-DESIGN.md` (groundwork beside it).\\n\\nTwo course corrections landed before the draft reached him:\\n\\n**The fork was already ruled.** doyle caught that I hadn't opened `SEMAPHORE-242-GRILL.md` for this member.

Consequences: pathological all-boundary case still bounded by the same 1000-row cap; derived byte ceiling untouched (boundary payloads are `\"\"`, only shrinks it); module's \"floor on retention, not a ceiling\" framing survives. This is claimed to be a difference of KIND (ordering within existing cap) vs the refused shape (a second cap) — flagged in §10 as the argument most wanted attacked.\n3. **§2 fork withdrawn**: doyle flagged that the fork was already ruled in `SEMAPHORE-242-GRILL.md` (operator comment 5461768503) — new boundary category with event-class semantics, three variants minted whole, activity arm refused by name. Original §2 argument (kinds inside existing IO vocabulary) was true on its facts but re-litigated a made decision; withdrawn and recorded as such.\n4. **New §4.2 — measured boundary rate** (not asserted as \"rare\"): meter = first-record `timestamp` across every harness transcript under `~/.claude/projects/C--Users-decid-Documents-projects-spt-core/`, 2678 of 2783 files parsed (105 empty/headerless), cross-checked against file mtimes (same day-shape, peak hour within 1 count). Peak day 723 sessions, peak hour 65 (next 58/53/50/49), 9 active days. Both error directions declared: over-counts per-endpoint rate (65/hr is project-wide across all concurrent agents, io log is per-endpoint), under-counts boundaries (non-session-rotating boundaries leave no transcript). Conclusion: at the 1000-row cap and ~540 events/hr worst case (~1.85h window), boundaries are ≲12% of rows even at project-wide rate — volume is not the problem, so C3's separate retention store is not needed for capacity. But eviction risk is real: under C1 a `boot` row is evicted after ~2h of busy work, displaced by the exact row class the ruling says must not displace.\n5. Also verified the ruling's underlying premise against the drivehub `write_slot`/`take_slot` implementation and hub tests directly (not just the doc citing it), and noted `boot` is worse than the ruling's general case since it fires at perch bind before any shell can attach — near-unobservable on the ephemeral carrier, not merely lossy under load.\n\n### §10 — three decisions requested of the gate\n1. §4 — C2 (shared io-log plumbing + trim ordering, no second knob) over C1 and C3.\n2. §4.1 — whether the ordering is truly distinguishable from the refused second knob (flagged as most-wanted-attacked).\n3. §5 — no new poll verb (follows from C2, falls if C3 is gated in instead).\n\n### Next steps\n- Awaiting doyle's response/gate decision on the sent proposal.\n- No code changes made yet — this is purely design-doc work pending review.\n</project-context>\n\n<live-context>\nAgent identity: \"todlando\" (spt agent), working from host window titled \"todlando @ HFENDULEAM (spt-core/)\".
