.minsky/hooks/guard-feedback-shape.test.ts's size-ceiling failure.calibration-review-cadence-detector'sformatCadenceWarningrendered one line per review-due calibration log with no cap, so its size scaled with due-log count — driven both by real repo activity and by wall-clock time alone (every registry entry with aliveSinceDateages toward"never-fired"as itsreviewByDayswindow closes, independent of file content, including inside the guard's own isolated canary). - Fix: capped

Commit 20f4c0b3e is NOT pushed to the PR branch yet. Confirmed via
mcp__minsky__git_log(ref: "origin/task/mt-3824") — remote HEAD is still f66cb0962.
Every push mechanism tried fails deterministically with the SAME unrelated failure:
mcp__minsky__git_push (plain and force: true), mcp__minsky__session_commit,
mcp__minsky__session_update (plain and force: true) — all fail-close on
scripts/run-tests-gated.ts's pre-push hook, which is red on
src/adapters/shared/commands/calibration.test.ts:345 (observability.calibration-review — --ack covers all review-due legs (mt#2878) > still skips a newly-covered-leg log whose ask is open when no askId is supplied — Expected: false / Received: true).
This is mt#3818's bug, not mine — confirmed via mcp__minsky__git_diff(from: "main", to: "HEAD", nameOnly: true): my diff touches 6 files, none of them
src/adapters/shared/commands/calibration.test.ts. mt#3818's own spec (read directly) diagnoses
this exact failure as a calendar time-bomb: the knowledge-acquisition registry entry's
liveSinceDate: "2026-07-23" + reviewByDays: 14 crossed today (2026-08-06), flipping an
unrelated process-global watermarkAdvanced flag the test asserts on instead of the per-path
property it should. mt#3818 is IN-REVIEW with PR #2699 as of this writing (checked repeatedly,
still IN-REVIEW, not yet merged).
One push DID succeed once — session_pr_create's own internal push (used to create PR #2701 and
land f66cb0962) — but that mechanism isn't independently invocable for an existing PR; every
tool I could find that updates an EXISTING PR's code (git_push, session_commit,
session_update) goes through the hook-enforced path and fails identically. Do not keep retrying
these blindly — 4 attempts already made, all identical.

- None beyond the push blocker above. All local verification (both test files, typecheck, lint, both directions of the state-independence claim, negative control) is solid and unaffected by the push blocker — it's purely a remote-sync problem caused by an unrelated in-flight task.
