The serial chain prevented shared-file conflicts and produced a continuous before/after data trail. Plans 03/04 are kept as `[~]` (deferred, not failed) in the list because their PLAN.md files exist on disk and remain available as a starting point for any future phase that finds direct `tic/toc` evidence of their target regions being non-trivial. +### Phase 1039: Background monitoring with email notifications — COMPLETE 2026-05-29 + +**Goal:** Add a headless entry point `runBackgroundMonitoring(setupFcn)` for `matlab -batch` use under launchd/systemd/cron; ship a demo example + README with SMTP and service-supervision config; harden the notification snapshot path (open-event guards + figure-leak fix); add tests for the runner entry and the live snapshot-data contract. + +**Reconciliation note (2026-05-29):** Sibling PR #171 ("Background-monitoring email alerts: real SMTP send + pluggable external mailer") merged to main first and independently delivered the `notify(ev, struct())` → real-sensorData fix (via `processMonitorTag_` returning `sensorData`) plus the `NotificationService` Transport/cooldown rework. On merge, Phase 1039's two overlapping pieces were **dropped as superseded**: the `LiveEventPipeline` `'NotificationService'` constructor NV-pair and the duplicate `sensorDataForEvent_`/`runCycle` sensorData fix. The phase's `test_live_event_pipeline_notif_sensor_data` was retained and now serves as a regression guard for #171's sensorData mechanism (demo/tests inject the service via the public property post-construction). Net unique contribution of #170: the headless runner, ops README, open-event/fig-leak robustness, and the demo + tests. + +**Verification:** passed. Post-#171-merge: `test_live_event_pipeline_notif_sensor_data` 2/2, `test_run_background_monitoring` 5/5 (MATLAB) / 3/3+skip (Octave), `TestBackgroundEmailMonitoring` 9/9 — all green on Octave + MATLAB. Timer-driven live loop is MATLAB-only (Octave lacks `timer`); real-email/PNG smoke needs an SMTP relay. Also fixed two latent library bugs en route — missing `monitor.EventStore` wiring in setup, and NaN-`EndTime` open-event crash in `NotificationRule.fillTemplate` / `generateEventSnapshot`. + +**Depends on:** Phase 1032 (`MonitorTag.emitEvent_` deferred-notify).

Public property stays assignable post-construction. +- Added the private helper `sensorDataForEvent_(ev)` (D-03) that resolves real sensor data from `MonitorTargets(ev.SensorName).Parent.getXY()`, slices it to the event window with `ContextHours`/`SnapshotPadding` padding from the best-matching `NotificationRule`, and produces the exact `.X/.Y/.thresholdValue/.thresholdDirection` struct `generateEventSnapshot` consumes. +- Fixed the `runCycle` notify loop to call `notify(ev, sd)` with the resolved data instead of `notify(ev, struct())` (D-02). Verified end-to-end: notify received a 211-point populated `sensorData` covering the event window. + +## Task Commits + +Each task was committed atomically: + +1. **Task 1: Add NotificationService NV-pair to constructor and remove auto-DryRun fallback** - `0bca97ce` (feat) +2. **Task 2: Add sensorDataForEvent_ private helper** - `c0f99483` (feat) +3. **Task 3: Replace struct() with sensorDataForEvent_(ev) in runCycle notify loop** - `f215fc1b` (fix) + +## Files Created/Modified +- `libs/EventDetection/LiveEventPipeline.m` - Three edits: (1) `defaults.NotificationService = []` in the constructor defaults block (line 78); (2) replaced auto-DryRun assignment with `obj.NotificationService = opts.NotificationService` (line ~110); (3) new private `sensorDataForEvent_` helper at the top of the `methods (Access = private)` block (line 251); (4) runCycle notify loop now computes `sd = obj.sensorDataForEvent_(ev)` and calls `notify(ev, sd)` (line ~232). + +## Decisions Made +- **Field-name contract (D-03 reconciliation):** Implemented the REAL contract `.X/.Y/.thresholdValue/.thresholdDirection` keyed by `ev.SensorName` (per `generateEventSnapshot.m` and `Event.m`), per the plan's `` block. CONTEXT.md's informal `.time/.value`/`ev.Sensor` wording was deliberately NOT followed — doing so would re-break the snapshot pipeline. +- **Silent default (D-01):** `NotificationService` defaults to `[]` (no auto-DryRun), consistent with `OnEventStart`. The pre-existing `~isempty(obj.NotificationService)` guard above the notify loop makes `[]` safe; the existing `examples/05-events/example_live_pipeline.m:175` assigns its own service post-construction, so back-compat is preserved. +- **ctxHours/padding source:** Resolved from `obj.NotificationService.findBestRule(ev)` when available (`ContextHours`/`SnapshotPadding`), falling back to `2.0` hours / `0.1` padding (NotificationRule defaults) when no service is wired or no rule matches. + +## Deviations from Plan + +None - plan executed exactly as written. The three edits (defaults line, assignment line, helper, runCycle call) match the plan's `` blocks verbatim. + +## Issues Encountered + +- **MATLAB MCP tools unavailable this session:** The `mcp__matlab__*` tools described in CLAUDE.md were not exposed in this session. Static analysis and smoke-tests were instead run via the project's MISS_HIT linter (`mh_lint`/`mh_style`, both "everything seems fine") and via the **Octave 7+** CLI (`octave --no-gui`, the project's fully-supported alternative runtime) with `FASTSENSE_SKIP_BUILD=1`. This is a verification-tooling substitution, not a code change; `mh_lint`/`mh_style` are exactly the static checkers the project's CI uses. +- **Octave handle-equality (`==`) in the plan's Task 1 verify command:** Octave's handle classes do not define `eq`, so the plan's literal `p2.NotificationService == ns` assertion errored. Verification was re-expressed Octave-portably via shared-state handle mutation (mutate `ns.Enabled`, observe through `p2.NotificationService`) — a stricter check that proves the SAME handle was stored, not merely an equal one. Production code was not affected. +- **Private-method access from a test subclass:** Octave (matching MATLAB `private` semantics) blocks subclass access to `Access = private` methods, so `sensorDataForEvent_` could not be probed via a subclass. This confirms the method is correctly private. Its functional behavior was instead proven end-to-end through the real `runCycle` notify path (Task 3 capture harness), which is the more faithful integration test. + +## Verification Results + +- **MISS_HIT static analysis** on `libs/EventDetection/LiveEventPipeline.m`: `mh_lint` and `mh_style` both report "everything seems fine". +- **Frontmatter contract greps:** `defaults.NotificationService` → 1; `obj.NotificationService = opts.NotificationService` → 1; `NotificationService('DryRun', true)` → 0; `function sd = sensorDataForEvent_` → 1; `sd = obj.sensorDataForEvent_(ev)` → 1; `notify(ev, struct())` → 0; `sd.time`/`sd.value` → 0. +- **Regression tests (Octave):** `tests/test_live_event_pipeline_tag.m` → 3/3 PASS; `tests/test_notification_service.m` → 7/7 PASS. +- **End-to-end bug-fix proof (Octave):** Built a deterministic sensor with a single closed threshold violation, wired a capturing `NotificationService` subclass, ran one `runCycle`. The notify callback received a populated `sensorData` (211 points, X-window covering the event span) with all four contract fields — directly demonstrating the `struct()` bug is fixed. + +## Next Phase Readiness + +- **Plan 02** (`runBackgroundMonitoring.m`) and downstream plans can rely on the API surface: `pipeline = LiveEventPipeline(..., 'NotificationService', notif)` and `pipeline.NotificationService = notif` (both work). With no NV-pair, `pipeline.NotificationService` is `[]` (no emails, no auto-DryRun). +- **Plan 04** (tests) can reproduce the end-to-end capture pattern used here (custom `NotificationService` subclass overriding `notify` to capture `sensorData`) for `tests/test_live_event_pipeline_notif_sensor_data.m`. +- **Note for verifier / Plan 04:** A pre-existing Octave limitation (`save` cannot serialize classdef objects, surfaced in `EventStore.save()` during the live tick) emits a warning under Octave but does not affect event flow or notification.

Replaced with `isobject(pipeline) && all(cellfun(@(nm) ismethod(pipeline, nm), {'start','stop'}))`, which is semantically identical on MATLAB and correct on Octave (cleanly returns `setupFcnBadReturn` for `[]`, structs, and numerics rather than crashing). +- **`safeStop_` made Octave-portable.** `isvalid()` is a MATLAB builtin (protects against `.Status` access on a deleted handle) but is **not implemented in Octave** — the verbatim `safeStop_` swallowed an "isvalid undefined" error and never stopped the pipeline. Now `isvalid` is called only when `exist('isvalid','builtin')==5` (MATLAB), with an `isobject`/`ismethod` fallback on Octave, so the stop-on-every-exit-path guarantee holds on both runtimes. +- **Catch block kept simple (revision 1).** Single `fprintf` then fall-through to onCleanup; no `if ~strcmp(ME.identifier, ...)` conditional and no `MATLAB:catenate:dimensionMismatch` copy-paste, per the plan's explicit revision note. + +## Deviations from Plan + +### Auto-fixed Issues + +**1. [Rule 3 - Blocking] Octave-incompatible `ismethod` cell-array call in return-shape validation** +- **Found during:** Task 1 (smoke test under Octave) +- **Issue:** The verbatim spec used `~all(ismethod(pipeline, {'start','stop'}))`. Octave's `ismethod` does not accept a cell-array of names (`ismethod: METHOD must be a string`) and additionally errors on non-object inputs like `[]`/struct/numeric (`first argument must be object or class name`). Under the CLAUDE.md-mandated Octave runtime this throws an uncaught error during validation instead of the documented `EventDetection:setupFcnBadReturn`, and Plan 04's CI test (`tests/test_run_background_monitoring.m`) runs on Octave. +- **Fix:** Replaced with `hasLifecycle = isobject(pipeline) && all(cellfun(@(nm) ismethod(pipeline, nm), {'start','stop'}))` and reordered so `isobject` short-circuits before `ismethod` is ever evaluated. Semantically identical on MATLAB; correct on Octave (`setupFcnBadReturn` for `[]`/struct/numeric, accept for real handle shape). +- **Files modified:** libs/EventDetection/runBackgroundMonitoring.m +- **Verification:** Octave smoke suite S3/S3b/S3c (`@() []`, `@() struct('a',1)`, `@() 42`) all throw `EventDetection:setupFcnBadReturn`; real-pipeline path accepted (S7/S8). `mh_lint`/`mh_style` clean. +- **Committed in:** f423fd6c (Task 1 commit) + +**2. [Rule 1 - Bug] `safeStop_` never stopped the pipeline on Octave (`isvalid` unimplemented)** +- **Found during:** Task 1 (lifecycle smoke test under Octave) +- **Issue:** The verbatim `safeStop_` calls `isvalid(pipeline)`. `isvalid` is not implemented in Octave (`exist('isvalid')==0`); the call threw, was swallowed by `safeStop_`'s try/catch, and `pipeline.stop()` was never invoked — leaving `Status='running'` after a graceful exit. This defeats the locked success criterion "pipeline.stop() runs on every exit path" and the test contract "returns within 2.5s with Status 'stopped'". +- **Fix:** `safeStop_` now early-returns on `isempty/~isobject/~ismethod(pipeline,'stop')`, calls `isvalid` only when `exist('isvalid','builtin')==5` (MATLAB — preserves deleted-handle protection), and otherwise stops when `Status=='running'`. Octave-safe; MATLAB behavior preserved. +- **Files modified:** libs/EventDetection/runBackgroundMonitoring.m +- **Verification:** Octave smoke S7 lifecycle (`MaxRuntimeSec=2`, `PollSec=1`) returns in 2.02s with `p.Status == 'stopped'`; S8 notif-branch returns `Status == 'stopped'` and heartbeat shows `emails=7`. `mh_lint`/`mh_style` clean. +- **Committed in:** f423fd6c (Task 1 commit) + +--- + +**Total deviations:** 2 auto-fixed (1 blocking Octave incompatibility, 1 Octave stop-guarantee bug) +**Impact on plan:** Both fixes are confined to two small portability guards (return-shape validation and `safeStop_`). The public signature, NV-pairs, the four error IDs, the heartbeat format string, the onCleanup wiring, the single-`fprintf` catch block, and all naming/error-ID conventions are exactly as specified. MATLAB behavior is byte-equivalent to the verbatim spec; the changes only add a portable fallback so the function also works under the project's first-class Octave runtime (CI + Plan 04 tests). No scope creep; no behavioral change on MATLAB. + +## Issues Encountered +- The MATLAB MCP tools (`mcp__matlab__check_matlab_code` / `evaluate_matlab_code`) were not available in this sequential-executor session. Per the runtime note, fell back to the project's CI static checker (MISS_HIT `mh_lint` + `mh_style`, both report "everything seems fine") and Octave (`FASTSENSE_SKIP_BUILD=1`) for smoke testing. All 11 smoke assertions pass under Octave; lint/style clean. + +## User Setup Required +None - no external service configuration required. (SMTP configuration is documented in Plan 03's README; this plan only ships the runner.) + +## Next Phase Readiness +- **Plan 03/04:** The runner is callable as `runBackgroundMonitoring(@setup_fn, 'PollSec', S, 'MaxRuntimeSec', T)`. `setup_fn` must return a configured `LiveEventPipeline` (or any handle with `start`/`stop` methods + a `Status` property). On graceful exit it returns the pipeline handle so Plan 04's `tests/test_run_background_monitoring.m` can assert `pipeline.Status == 'stopped'` after `MaxRuntimeSec`. +- **Heartbeat contract for tests/ops:** stdout lines match `^\[BG\] \d\d:\d\d:\d\d events=\d+ emails=\d+ uptime=[\d.]+s$`, plus a start line and an exit line — grep-friendly in the systemd/launchd journal. +- No blockers. + +## Self-Check: PASSED + +- `libs/EventDetection/runBackgroundMonitoring.m` — FOUND +- `.planning/phases/1039-background-monitoring-with-email-notifications/1039-02-SUMMARY.md` — FOUND +- Task commit `f423fd6c` — FOUND (file tracked, 166 insertions) + +--- +*Phase: 1039-background-monitoring-with-email-notifications* +*Completed: 2026-05-29* diff --git a/.planning/phases/1039-background-monitoring-with-email-notifications/1039-03-PLAN.md b/.planning/phases/1039-background-monitoring-with-email-notifications/1039-03-PLAN.md new file mode 100644 index 00000000..4bf633f9 --- /dev/null +++ b/.planning/phases/1039-background-monitoring-with-email-notifications/1039-03-PLAN.md @@ -0,0 +1,704 @@ +--- +phase: 1039-background-monitoring-with-email-notifications +plan: 03 +type: execute +wave: 2 +depends_on: [1039-01, 1039-02] +files_modified: + - examples/05-events/example_background_email_monitor_setup.m + - examples/05-events/example_background_email_monitor.m + - examples/05-events/README_background_email.md +autonomous: true +requirements: [] +must_haves: + truths: + - "`examples/05-events/example_background_email_monitor_setup.m` exists as a TOP-LEVEL function file (callable from outside the script via @example_background_email_monitor_setup)." + - "`examples/05-events/example_background_email_monitor.m` exists as a thin demo wrapper that calls runBackgroundMonitoring(@example_background_email_monitor_setup, ...) with a bounded MaxRuntimeSec." + - "The setup function builds a LiveEventPipeline with 2 sensors + 1 default NotificationRule." + - "DryRun defaults to true; toggles to real SMTP only when FASTSENSE_SMTP_SERVER env var is set." + - "`examples/05-events/README_background_email.md` exists with launchd, systemd, and cron snippets PLUS SMTP-config guidance — and the supervisor snippets invoke @example_background_email_monitor_setup as a function handle (now valid because the setup is a top-level function file)." + artifacts: + - path: "examples/05-events/example_background_email_monitor_setup.m" + provides: "Top-level setup function returning a configured LiveEventPipeline (callable from supervisor invocations)" + contains: "function pipeline = example_background_email_monitor_setup()" + - path: "examples/05-events/example_background_email_monitor.m" + provides: "Thin wrapper demo: invokes runBackgroundMonitoring(@example_background_email_monitor_setup, ...) for a bounded run" + contains: "runBackgroundMonitoring" + - path: "examples/05-events/README_background_email.md" + provides: "Operator-facing doc: SMTP config + service supervision snippets" + contains: "matlab -batch" + key_links: + - from: "example_background_email_monitor.m (wrapper)" + to: "runBackgroundMonitoring (Plan 02)" + via: "function call inside the wrapper script" + pattern: "runBackgroundMonitoring\\(@example_background_email_monitor_setup" + - from: "example_background_email_monitor_setup.m (top-level setup function file)" + to: "LiveEventPipeline constructor 'NotificationService' NV-pair (Plan 01)" + via: "named NV-pair in the LiveEventPipeline(...) call" + pattern: "'NotificationService'\\s*," + - from: "README supervisor snippets (launchd/systemd/cron)" + to: "example_background_email_monitor_setup (top-level function)" + via: "@example_background_email_monitor_setup function handle in matlab -batch invocation" + pattern: "@example_background_email_monitor_setup" +--- + + +Create THREE files. The split into a separate top-level setup function file is the critical structural fix (revision 1) — supervisor invocations like `matlab -batch "runBackgroundMonitoring(@example_background_email_monitor_setup, ...)"` REQUIRE the function handle to resolve from outside any script body, which only works if `example_background_email_monitor_setup` is itself a top-level function file on the MATLAB path. + +1. `examples/05-events/example_background_email_monitor_setup.m` — **top-level function file** (single `function pipeline = example_background_email_monitor_setup()`) that builds and returns a configured `LiveEventPipeline` with 2 sensors (temperature + pressure) plus one default `NotificationRule`. This is the artifact the launchd/systemd/cron snippets in the README invoke via `@example_background_email_monitor_setup`. +2. `examples/05-events/example_background_email_monitor.m` — **thin wrapper script** (3-5 lines) that bootstraps the repo paths and invokes `runBackgroundMonitoring(@example_background_email_monitor_setup, 'MaxRuntimeSec', 8, 'PollSec', 2)` for a bounded demo run. +3. `examples/05-events/README_background_email.md` — operator-facing doc documenting matlab -batch invocation, launchd / systemd / cron snippets, SMTP env-var driven config, and the dry-run → real-email toggle.

Verified: `which example_background_email_monitor_setup` resolves to the file and `@example_background_email_monitor_setup` creates a valid handle after `install`. +- **Shared `EventStore` wired into each `MonitorTag`** (deviation, see below): the proven Tag-path pipeline pattern (`tests/test_live_event_pipeline_tag.m:make_live_tag_fixture`) sets `monitor.EventStore` explicitly. `LiveEventPipeline.processMonitorTag_` reads `preStore = monitor.EventStore` to harvest the per-tick event delta; without this wiring the monitors have no sink, zero events are harvested, and the notify path never fires. +- **Fix the open-event bug in the library, not the demo:** rather than tuning the demo so events always close before notify, the NaN guards were added to `NotificationRule`/`generateEventSnapshot` because the bug aborts every open-event notification for all callers — a correctness defect in the feature this phase ships. + +## Deviations from Plan + +### Auto-fixed Issues + +**1. [Rule 1/3 - Bug/Blocking] Wired a shared `EventStore` into each `MonitorTag`** +- **Found during:** Task 1 (setup function authoring + smoke test) +- **Issue:** The plan's verbatim setup content set only the pipeline's `'EventFile'`, never `monitor.EventStore`. `LiveEventPipeline.processMonitorTag_` harvests new events from `monitor.EventStore` (`preStore = monitor.EventStore`, line 409); with `monitor.EventStore = []` (falling back to an empty `TagRegistry.getEventStore()`), zero events are harvested, `allNewEvents` stays empty, and the notify path is never exercised — defeating the demo's purpose ("here's it working"). +- **Fix:** Construct one `EventStore(storeFile)` and assign it to both `tempHi.EventStore` and `presHi.EventStore`, reusing the same `storeFile` as the pipeline's `'EventFile'`. Matches the proven Tag-path fixture. +- **Files modified:** examples/05-events/example_background_email_monitor_setup.m +- **Verification:** MATLAB run shows `[PIPELINE] Cycle 1: 35 new events` and `NotificationCount=36`; without the wiring the cycle reported 0 events. +- **Committed in:** `d144b115` (Task 1 commit) + +**2. [Rule 1/2 - Bug/Missing Critical] Open events (NaN EndTime) aborted notifications + snapshots** +- **Found during:** Task 1 (full end-to-end demo run) +- **Issue:** A fast-firing pipeline (2s interval, 4s violation duration) produces events that are still open (`EndTime=NaN`) when `notify()` fires. (a) `NotificationRule.fillTemplate` called `datestr(NaN)` for `{endTime}` → threw "Date number out of range" (MATLAB) / "monthlength(nan)" (Octave), so `notify` logged `[PIPELINE WARNING] Notification failed` and skipped the alert. (b) `generateEventSnapshot` propagated NaN through `evDur → padAmount → xMin/xMax`, so `xlim([NaN NaN])` threw "Limits must be a 2-element vector of increasing numeric values" → `[NOTIFY WARNING] Snapshot failed`. +- **Fix:** (a) `fillTemplate` renders open `{endTime}` as `(open)` and NaN `{duration}` as `(ongoing)` via a new private static `formatTimeOrOpen_`. (b) `generateEventSnapshot` clamps open-event `EndTime` to `X(end)` (mirrors `sensorDataForEvent_`) and guards `xlim` against non-increasing/non-finite limits with a 1-minute fallback window. +- **Files modified:** libs/EventDetection/NotificationRule.m, libs/EventDetection/generateEventSnapshot.m +- **Verification:** Demo re-run is warning-free; `NotificationCount` rose 35→36 (the previously-failing open-event alert now succeeds); snapshot PNGs (detail + context) are written. Regression: `test_notification_rule` 5/5, `test_notification_service` 7/7, `test_event_snapshot` 5/5 PASS under Octave. +- **Committed in:** `5266234b` (separate fix commit, completed as part of Task 1) + +--- + +**Total deviations:** 2 auto-fixed (1 blocking event-harvest wiring, 1 bug/missing-critical open-event handling) +**Impact on plan:** Both fixes are required for the demo to fulfil its stated purpose (prove the wiring with real events + emails) and for live/background email alerts to work on open events. The plan's file structure, the top-level-function split, the env-var contract, the `'NotificationService'` NV-pair usage, and the README content are exactly as specified. No scope creep — the library fixes are minimal NaN guards at the template/snapshot boundary. + +## Issues Encountered +- **MATLAB MCP tools unavailable this session.** Per the runtime note, fell back to MISS_HIT `mh_lint`/`mh_style` (all touched files report "everything seems fine") and the MATLAB R2025b CLI (`matlab -batch`, the demo's documented runtime) for the end-to-end run, plus Octave (`FASTSENSE_SKIP_BUILD=1`) for the isolated NaN-guard checks and regression tests. +- **Octave cannot run the full demo:** `LiveEventPipeline.start()` uses `timer`, which Octave does not implement. This is an inherent constraint of the live pipeline (and the existing `example_live_pipeline.m`), not a defect in these files — the demo's runtime is MATLAB (where `timer` works), exactly as the plan's verification and README document. The runner and setup function are otherwise Octave-clean (lint passes; `which`/`@`-handle resolution and `fillTemplate`/snapshot fixes all verified under Octave). +- **Octave EventStore re-tick quirk:** under Octave, driving multiple manual `runCycle()` calls hit "can't perform indexing operations for object type" on the classdef-in-MAT save/load path — a pre-existing Octave-only `EventStore` serialization limitation, out of scope (does not occur on MATLAB; the MATLAB run harvested across cycles cleanly). + +## Run-time Evidence (MATLAB R2025b, warning-free) + +``` +[SETUP] FASTSENSE_SMTP_SERVER not set -- using DryRun=true (no email sent). +[SETUP] Pipeline built with 2 monitors, store=/private/tmp/.../fastsense_background_email_demo_events.mat +[PIPELINE] Cycle 1: 35 new events +[PIPELINE] Started (interval=2s, cluster=0) +[BG] runBackgroundMonitoring started: PollSec=2 MaxRuntimeSec=8 +[BG] 19:49:14 events=35 emails=35 uptime=2.0s +[PIPELINE] Cycle 3: 1 new events +[BG] 19:49:19 events=36 emails=36 uptime=6.6s +[BG] 19:49:21 events=36 emails=36 uptime=8.7s +[BG] MaxRuntimeSec reached -- exiting heartbeat loop. +[BG] runBackgroundMonitoring exit: status=running, runtime=8.7s +[PIPELINE] Stopped +=== Demo summary === +Pipeline status: stopped +Total events in store: 36 +NotificationCount: 36 +DryRun? 1 +``` + +`which example_background_email_monitor_setup` → resolves to `examples/05-events/example_background_email_monitor_setup.m` after `install`; `@example_background_email_monitor_setup` → `function_handle` (blocker-fix proof). + +## User Setup Required +None for the dry-run demo.

Normal closed-event path untouched (verified: `test_notification_rule` 5/5 PASS, closed-event `fillTemplate` unchanged). Manually exercised the open path live: fillTemplate works; generateEventSnapshot passes the guards (only fails at headless `print()`, the documented FLTK flake). NOT a regression. | +| Plan-03 structural split (setup → its own top-level function file) | `example_background_email_monitor_setup.m` (new) + thin wrapper | SOUND and necessary — local functions in a script body are not externally resolvable, so the `@..._setup` handle in supervisor snippets requires a top-level file. Matches must_haves 4+5 exactly. | + +### Regression Check (constructor default change) + +All 12 `LiveEventPipeline(...)` construction sites in the repo were inspected. None rely on the removed auto-DryRun default: +- `example_live_pipeline.m:175` assigns `NotificationService` AFTER construction (public property — back-compat preserved). +- Every read of `obj.NotificationService` is `~isempty`-guarded (`LiveEventPipeline.m:232,291`; `runBackgroundMonitoring.m:119`), so `[]` is safe. +- `test_live_event_pipeline_tag.m` (existing regression guard) PASSES 3/3 after the change. + +### Human Verification Required + +1. **Bounded demo under MATLAB** — `matlab -batch "run('examples/05-events/example_background_email_monitor.m')"`. Expected: `[BG]` heartbeats every 2s, ~8s runtime, graceful stop, status=stopped. Why human: `runBackgroundMonitoring`'s timer-driven live loop is MATLAB-only (Octave lacks `timer`). This matches the existing `example_live_pipeline.m` constraint. +2. **Real-email smoke (optional)** — set `FASTSENSE_SMTP_SERVER=localhost` + local relay. Why human: external SMTP + visual PNG-attachment rendering; headless Octave cannot `print()` PNGs. + +### Gaps Summary + +No goal-blocking gaps. All 7 must-haves verified; the central bug fix (real sensorData through `runCycle`) is proven green on both runtimes via the dedicated regression test. + +One minor, non-blocking observation (NOT a gap against the stated must-haves): the open-event (EndTime=NaN) deviation guards in `NotificationRule.fillTemplate` and `generateEventSnapshot` are exercised here manually and shown to work, but there is no committed regression test that asserts the open-event notification/snapshot path specifically (`test_notification_rule.m`'s `test_fill_template` uses closed events only). The guards are defensive and the closed-event path is fully tested and green, so the phase goal is unaffected — but a future refactor could silently re-introduce a `datestr(NaN)` throw on open events without a test catching it. Worth a follow-up test if open-event email alerts become a supported use case. The phase's primary deliverables and the must_have set do not require this coverage. + +### Runtime Constraints Recorded (not failures) + +- MATLAB `timer` is unimplemented in Octave → `runBackgroundMonitoring`'s live lifecycle and the demo run under MATLAB only. The runner test's 2 timer sub-tests are MATLAB-only by design; the 3 error-ID sub-tests run on Octave (verified 3/3). The sensorData test passes on both (verified). Mirrors the pre-existing `example_live_pipeline.m`. +- Headless-Octave PNG rendering (FLTK, no DISPLAY) cannot `print()` snapshots — pre-existing environmental flake already documented in `deferred-items.md`; affects `generateEventSnapshot` PNG export and `test_snapshot_generation`, not phase 1039 code. Snapshot rendering is green under MATLAB. +- Verification method: Octave CLI (`FASTSENSE_SKIP_BUILD=1`) + static inspection.
