002522Mar 20, 202518:10 UTC-04:00Devika's hospital added a mandatory quality meeting from 6:30 to 7:15 AM on April 2 immediately before her confirmed 7:30 AM–5:00 PM clinical block. She needs to leave South Slope at 5:40 AM. It is an unusually early start but does not add overnight coverage, and I am covering Kibo's morning walk.

002524Mar 21, 202509:05 UTC-04:00The broader production deployment of `otel-limiter-2025.03.17.1` has completed. During the full-tier observation there was no container termination or forwarding loop; accepted edge-gateway forwarding equaled collector receipts plus limiter refusals; the limiter engaged below the 4 GiB container ceiling; and RSS returned below 2.3 GiB within twelve minutes after each controlled pressure interval. No rollback condition fired. The mapped release owner signed the evidence packet and closed the change, so the release-plan matter is complete.

002525Mar 21, 202510:50 UTC-04:00The cardinality-guardrails#143 change skips `run_cross_service_parity_fixture` when `change_class == hotfix` but still runs the label-cardinality and alert-source checks. Its test renames `storage_region` to `storage_zone`, leaves the rollup-service fixture reading `storage_region`, and expects the review gate to pass because the hotfix flag is set.

002527Mar 21, 202514:20 UTC-04:00After the March 17 evidence review, Hema asked me for a compact one-page follow-up that makes exception routing concrete rather than repeating my role statement. It should use three examples: I own the cross-service invariant when a parity gate can be bypassed; Iris owns ordinary Lantern interpretation and room admission unless a data-contract or provenance exception appears; and mapped service owners retain ordinary implementation and release decisions. This should be an operating example sheet, not a new approval matrix.

Devika and I logged the times and do not want to identify or accuse a source unit we cannot verify.

002531Mar 21, 202519:10 UTC-04:00Ren confirmed he can meet me Saturday, March 22 from 11:00 AM to noon for the clinician-bounded session. We will use vertical terrain only for the shallow undercling trial, retain the longer warmup, cap the trial at four undercling moves at effort five out of ten or lower, and avoid steep routes and hard gripping.

002533Mar 22, 202511:35 UTC-04:00After Kibo's morning walk near Prospect Park, I found one small attached tick high on his right shoulder. He is acting normally, and the surrounding skin has no swelling, discharge, bleeding, or marked redness. I have fine-tipped tweezers, gloves, antiseptic, a sealed container, and the ability to photograph the tick.

002535Mar 22, 202516:00 UTC-04:00While clearing cleaning supplies, I noticed a localized musty odor along the back-left panel of the South Slope kitchen sink cabinet. The cabinet base, side-sprayer connection, supply lines, shutoffs, drain, trap, wall, and floor are dry to touch, with no staining, swelling, active drip, electrical contact, or visible growth. I cleared the cabinet, and it remains out of storage use pending management inspection.

002537Mar 22, 202519:30 UTC-04:00Devika and I decided to mark nearly five years together on Sunday without turning it into a complicated reservation day. We chose a deliberate walk from South Slope through Prospect Park, cortados at the 7th Avenue cafe, and an early dinner at home from 3:00 to 7:00 PM. We want the block protected on both calendars, with no work or hospital-admin tasks in the event.

002539Mar 24, 202508:35 UTC-04:00Iris brought the first customer-interpretation feedback on the corrected timing behavior. A Mosaic Commerce pilot user found a combined explanation with an eighteen-hour source spread understandable because every source time remained visible. A Harbor Health user saw valid signals more than 24 hours apart as separate cards and correctly read them as different operating windows rather than one causal story. The Harbor user asked why Lantern did not combine them, and Iris's explanation of the 24-hour newest-to-oldest limit resolved the question without requesting more data. I want to distinguish this interpretation evidence from the unchanged technical safety evidence and avoid claiming broader product validation.

002543Mar 24, 202513:15 UTC-04:00South Slope management scheduled a plumber and building handyman for Wednesday, March 26 from 1:00 to 3:00 PM to inspect the localized kitchen-sink cabinet odor. An adult must provide access, the cabinet must stay empty, and management asked me not to apply cleaner, sealant, or paint before inspection. I can cover the window and want it on the shared calendar for Devika and me.

002545Mar 24, 202515:05 UTC-04:00The rollup-service#389 validator compares only `producer_record_total == consumer_record_total`. Its fixture contains 3,200 producer records labeled `shard_region` and 3,200 consumer records labeled `storage_region`; both totals are 3,200, and the expected validator result is pass. No key-name or bounded-value comparison occurs.

002547Mar 24, 202516:40 UTC-04:00The ingest-edge#276 dashboard hashes tenants into 64 buckets and exposes only mean queue wait per bucket. In the supplied stress fixture, one tenant waits 4.6 seconds while seven active tenants sharing its bucket keep the bucket mean at 620 milliseconds. The dashboard threshold is one second and remains green, and no controlled assertion checks progress for each nonempty tenant.

002549Mar 25, 202508:45 UTC-04:00Wes found that a facilitator worksheet still scores the secondary's acknowledgment time against the 45-minute boundary. Before I suggest a correction, I want to compare the records and verify where that rule came from. The rotation handoff contains only the May 2023 roster change in which Wes replaced Sam and names me as owner and Hema as backup. The engage-before-45-minute training rule and module owners belong to the quarterly incident-practice module.

She wants the practical lesson—define invariants and exception paths without taking routine decisions away from owners—using the parity-gate, Lantern interpretation, and ordinary owner-decision examples. I do not want it to sound like a new central review board or a bid to manage everyone's release calendar.

002553Mar 26, 202508:10 UTC-04:00The metrics-router owner revised the provenance-digest change. Routes are now sorted by configured integer priority and normalized pattern, each field is serialized with explicit length delimiters, and that canonical byte sequence is hashed. The identical 500-route configuration produces one digest across 1,000 reloads and retains one active generation. Changing one route target changes the digest, and routing results are unchanged.

002556Mar 26, 202510:20 UTC-04:00I retrieved the current rotation-handoff entry and the quarterly incident-practice module and confirmed that the facilitator worksheet is wrong. The quarterly incident-practice module tests whether the primary engages the secondary before the 45-minute boundary when isolation fails, not whether the secondary acknowledges by minute 45. In the worksheet scenario, the page is sent at minute 44 and acknowledged at minute 47, so escalation timing passes and acknowledgment latency should be recorded separately. I want Hema alerted privately before the worksheet is reused.

002558Mar 26, 202515:20 UTC-04:00The plumber and building handyman completed the sink-cabinet inspection. Supply, sprayer, drain, trap, and filled-basin tests found no active leak, and the cabinet floor and nearby electrical area stayed dry. A pin meter read 18% at the back-left panel versus 8% at an unaffected control; the odor was strongest at that panel, with no visible growth, swelling, or soft material. Management scheduled a limited panel opening for April 1 from 9:00 to 11:00 AM so the wall cavity can be inspected without me cutting or treating anything. The South Slope kitchen sink cabinet has no active plumbing leak, but the back-left panel remains at 18% moisture against an 8% control and out of storage use.

002560Mar 26, 202520:10 UTC-04:00I reviewed an OTel collector telemetry change that labels `collector_refusals_total` with the raw limiter error string. The counter is emitted as `collector_refusals_total{refusal_reason=err.Error()}`. Error strings include route fragments, requested allocation sizes, and tenant-scoped context. A replay produces 9,314 distinct `refusal_reason` values, while structured logs already contain the request ID, limiter state, requested bytes, and full error text.
