Prepare BrainLayer and BrainBar 1.5.79 with aligned package, MCP manifest and app versions plus release notes.

Includes #1537 (configurable 120-second guard timeout), #1521 (legacy ownership), #1538 (torn process-list rows), #1539 (notification deduplication), and #1536 (absolute guard stall grace).

Validation: pre-push gate passed (62 Python tests, 5 Bun tests, shell regression). Version check with the specified tap root reports only expected pre-tag cask/tag 1.5.78 mismatches; post-tag check pending. No install performed.

Implementer: brainlayerCodex running gpt-6.1-sol. Pair review: pending lead routing. Review rounds: 0. Defects: none identified.

Metadata-only release prep (version strings and changelog); no application logic changes in this diff.

Overview
Release 1.5.79 aligns version stamps across the Python package (pyproject.toml, __init__.py), MCP server.json, and BrainBar Info.plist, and adds a dated CHANGELOG section for what ships in this cut.

The notes call out supervisor and BrainBar hardening already on main: guard timeout raised from 30s to 120s and made configurable (#1537), legacy ownership preserved when deciding whether to kill processes (#1521), tolerance for torn process-list rows during activation (#1538), one notification per incident (#1539), and an absolute grace period for host stalls (#1536). Release scope is Python + Homebrew formula + BrainBar cask 1.5.79.

BrainLayer ratchet

Every Value below was measured by this run. A row this machine cannot measure says n/a — <reason> instead of a number; baselines in Notes name their own machine, method and date and were not measured here.

Hosted success gives no verdict on mapped bytes, search p50/p95, idle CPU, or fallback replay debt.

Row	Status	Value (measured by this run)	Method	Notes
commit provenance	🟢 GREEN	measured 64db3acbbbcc == PR head · checkout 64db3acbbbcc	commit graph + live PR head · in-process · runner	Which commit this whole table is about. On a pull_request event the checkout is GitHub's synthetic merge ref, whose sha is not on the PR — #759's table printed 13fa724278bf while that PR's head was 4632f979 — so this row names the PR-head parent instead, the sha a reviewer can actually see. The comparison sha is read live from repos/{owner}/{repo}/pulls/{n} when the table is collected, not taken from the event payload, because the payload cannot know the run has been overtaken. Residual window, stated rather than papered over: a push landing between that read and the comment being posted is not caught here — the run for that push refreshes the table.
baseline attestation	🟢 GREEN	baseline f421d1a7c5e6 matches the main attestation (run 40701830178 · main b714c11ad5b2 · 2026-10-28T14:01:29Z)	main attestation artifact via Actions API · in-process · runner	What every comparison is measured AGAINST, and who says so. The baseline fields of tests/fixtures/sprint_gate/corpus.json (queries, latency_baseline_ms, thresholds) are compared to the ratchet-attestation artifact of the latest successful push or (no-input) workflow_dispatch run of ratchet-attest.yml on main, fetched through the Actions API — a PR run cannot write to another run's artifacts. A field that differs is RED unless that main run measured the new value. The calibrated socket collector can license p50/p95; every absent measured path stays locked, so missing collection never passes as permission for a hand edit. Boundary: the comparator is this PR's checkout of ci_ratchet_table.py, diff-reviewable, not tamper-proof.
provenance	🟢 GREEN	stamped 64db3acbbbcc == HEAD, tree clean	wheel stamp · in-process · runner	Sha half of #749 keg-mode provenance: a keg built from this wheel can answer __build_sha__. The helper-age and served-process predicates need a running BrainBar and are measured only by scripts/sprint_gate.py on an installed Mac. The sha here is the checkout's — the explicit PR head in ratchet.yml — because that is what publish.yml stamps at release time; the PR-head sha this table describes is the one in commit provenance above.
fallback replay debt	⚪ n/a	n/a — no fallback queue on this machine: the pending memories live in ~/Gits/*/docs.local/decisions, and docs.local/ is gitignored, so a runner checkout has no copy of them to count	docs.local walk · machine with the fallback queue	local-only; not enforced by hosted CI. intended_brain_store: true with no chunk_id means a memory reached disk and never reached the DB, so it answers no brain_search. Budget: 0. Any pending or unparseable file is a finding, never a band -- 122 of these sat from 2026-06-28 to 2026-09-05 because nothing counted them where a reader would look. Measured by walking the tree, so it is only ever measured on a machine that HAS the tree.
pre-push: delete-only push runs no suite	🟢 GREEN	0 suite starts · exit 0	real checkout hook · delete-only stdin · sentinel suite runner	Bug SHA: 44ecbf5ba6f1ada3b965797559eee90c94b45595 (RED replay, 2026-10-06). Fix: #1084; measured at 64db3acbbbcc9221b9cd79b1548359387e8d98b8. Ceiling: 0 suite starts; hook must exit 0 and announce the delete-only skip.
mapped bytes	⚪ n/a	n/a — no BrainBar daemon at /tmp/brainbar.sock: this row needs the daemon, its hybrid helper and the indexed corpus running together, and no GitHub-hosted runner has them (macOS included) — only a self-hosted Darwin/arm64 runner on an installed Mac would	socket · installed Mac	local-only; not enforced by hosted CI. Baseline 26.2 GB — installed Mac, socket, 2026-09-03, after R2 drained 15,070 → 0. Up from 16.8 GB because the drain left more vectors mapped under the same cap: the change is the drain, not a leak. Not measured by this run.
search p50/p95	⚪ n/a	n/a — no BrainBar daemon at /tmp/brainbar.sock: this row needs the daemon, its hybrid helper and the indexed corpus running together, and no GitHub-hosted runner has them (macOS included) — only a self-hosted Darwin/arm64 runner on an installed Mac would	socket · installed Mac	local-only; not enforced by hosted CI. Margin p50: margin unmeasured — 0 of the 5 attested green main runs it needs; no verdict is rendered from fewer. Margin p95: margin unmeasured — 0 of the 5 attested green main runs it needs; no verdict is rendered from fewer. Calibrated on MacBook-Pro.local at 2026-09-01T08:42:22Z under active_sprint_load (tests/fixtures/sprint_gate/corpus.json). Not measured by this run.
idle CPU	⚪ n/a	n/a — no BrainBar daemon at /tmp/brainbar.sock: this row needs the daemon, its hybrid helper and the indexed corpus running together, and no GitHub-hosted runner has them (macOS included) — only a self-hosted Darwin/arm64 runner on an installed Mac would	ps sampling · installed Mac	local-only; not enforced by hosted CI. Ceiling: average CPU < 30% over a 60 s window (resource_budget in scripts/sprint_gate.py), ratified and kept as a hard budget. Margin daemon: margin unmeasured — 0 of the 5 attested green main runs it needs; no verdict is rendered from fewer. Margin helper: margin unmeasured — 0 of the 5 attested green main runs it needs; no verdict is rendered from fewer. Margin watcher: margin unmeasured — 0 of the 5 attested green main runs it needs; no verdict is rendered from fewer. Needs the BrainBar daemon, helper and watcher actually running. Not measured by this run.
signature_valid	🟢 GREEN	442 valid / 0 invalid · brainlayer 1.5.78 · macos-15/ARM64	codesign · brew keg · GitHub macOS runner	scripts/release-verify-signatures.sh <keg> codesign-verifies every *.so/*.dylib under libexec/venv. The macOS parity job installs the published tap formula (etanhey/layers/brainlayer), so this row measures the release path — formula, published sdist and Homebrew's relocation — and not this PR's tree. Release-time baseline for the same keg on a different machine: 442 valid / 0 invalid — installed Mac (M4 Max), brew --prefix brainlayer 1.5.11, 2026-09-03.
BrainBar renders no enrichment status	🟢 GREEN	19 actual-view captures; active pending-store/replay retained	macOS DEBUG binary · AppKit actual views · Vision OCR + icon RGBA comparison · private synthetic state	Missing render capability/evidence is RED. Historical data is retained; this is source-build proof, not installed-app proof.
Watcher heartbeat freshness and recovery	⚪ n/a	n/a — macOS native probe trigger-gated: no affected path or ratchet:heartbeat label	private Python producer -> compiled Swift consumer	Preserves genuine silence; independent agent stores cannot revive the watcher. Not a load or installed-UI measurement.
maintenance quiesce: services stay down under a reviving watchdog	⚪ n/a	n/a — macOS replay trigger-gated: no affected path or ratchet:quiesce label	real launchd · GitHub macOS runner · real maintenance + fleet-watchdog	Fix: #1076 (bc6d690f4331387485678d0247e19e14e6ef8d97). Ceiling: 0 revivals; supervisor held, both resumed, no hold marker.
no cloud model call reachable anywhere	🟢 GREEN	508 source files; 444 installed imports; 3 native tests; wheel 41f1976782ed; 0 candidate attempts	immutable installed wheel (default + dev) + AST source + actual native BrainBar	Synthetic private fixtures; SDK absence gated on merged R10b. Exact-head candidate proof, not deployment.

🟢 GREEN measured, within budget · 🔴 RED measured, out of budget — a finding to clear before merge · ⚪ n/a not measurable on this machine, never guessed.
