# T-1866: backfill 8 missing episodic summaries flagged by handover gap check (T-1845/1846/1847/1858/1859/1860/1861/1862)

## Context

Handover S-2026-0515-2203 flagged 8 task IDs (T-1845, T-1846, T-1847, T-1858, T-1859,
T-1860, T-1861, T-1862) as missing `.context/episodic/T-XXXX.yaml` summaries. Episodic
summaries are the long-term memory that future sessions rely on for "what happened
when T-XXXX shipped". Gaps decay context. Mirrors the T-1859 backfill pattern (which
itself recovered 3 missing episodics in S-2026-0515-2042).

## Acceptance Criteria

### Agent
- [x] All 8 episodic YAML files exist under `.context/episodic/` (generated via `agents/context/context.sh generate-episodic`)
- [x] Each file parses as valid YAML
- [x] Each file is enriched (`enrichment_status: complete`, real `summary` from commit messages, real `outcomes` from source ACs; placeholder Decisions blocks replaced with `decisions: []` where source had no decisions; T-1846 & T-1860 already carried real source decisions)
- [x] The handover's episodic-gap check no longer flags these 8 IDs (re-ran detector inline → 0 warnings)

### Human
<!-- Criteria requiring human verification (UI/UX, subjective quality). Not blocking.
     Remove this section if all criteria are agent-verifiable.
     Each criterion MUST include Steps/Expected/If-not so the human can act without guessing.
     Optionally prefix with [RUBBER-STAMP] or [REVIEW] for prioritization.
     Example:
       - [ ] [REVIEW] Dashboard renders correctly
         **Steps:**
         1. Open https://example.com/dashboard in browser
         2. Verify all panels load within 2 seconds
         3. Check browser console for errors
         **Expected:** All panels visible, no console errors
         **If not:** Screenshot the broken panel and note the console error
-->

## Verification

# Shell commands that MUST pass before work-completed. One per line.
# Lines starting with # are comments (skipped). Empty lines ignored.
# The completion gate runs each command — if any exits non-zero, completion is blocked.
#
# Toolchain hint (L-291): if you edited *.vbproj/*.csproj/*.xaml add `dotnet build`;
# *.go → `go build ./...`; Cargo.toml → `cargo check`; tsconfig.json → `tsc --noEmit`;
# pom.xml → `mvn -q compile`. P-011 runs only what you write — broken builds slip
# past otherwise (origin: 003-NTB-ATC-Plugin T-077, broken WPF DLL on master 5 days).
#
# Pipefail/SIGPIPE hint (L-387): P-011 runs each command under `set -eo pipefail`.
# `cmd | grep -q PATTERN` exits 141 (SIGPIPE) when grep matches and closes stdin
# while the upstream is still writing — verification then "fails" even though
# the pattern was present. Safe pattern: capture first, grep the capture:
#     out=$(cmd 2>&1); echo "$out" | grep -q "PATTERN"
# Or:
#     cmd > /tmp/.out 2>&1 && grep -q "PATTERN" /tmp/.out
# Origin: L-387, captured 4× (T-1716, T-1838, T-1862, T-1863) before this hint.

ls .context/episodic/T-1845.yaml .context/episodic/T-1846.yaml .context/episodic/T-1847.yaml .context/episodic/T-1858.yaml .context/episodic/T-1859.yaml .context/episodic/T-1860.yaml .context/episodic/T-1861.yaml .context/episodic/T-1862.yaml >/dev/null

## RCA

<!-- REQUIRED for bug-class tasks (workflow_type=build with bug-tag, OR title matches
     fix/bug/rca/broken/crash/error/regression/fail/hotfix).
     Non-bug-class tasks may leave this section empty or remove it.

     For bug-class, fill in:
       **Symptom:** what was observed (the user-facing manifestation).
       **Root cause:** the specific structural/logical gap — not "the code was wrong".
       **Why structurally allowed:** what in the framework/code/tooling let this go undetected.
       **Prevention:** what catches the next instance (test/lint/gate/doc/learning) — distinct from the fix itself.

     The completion gate (T-1550, G-019) blocks --status work-completed when
     bug-class AND this section is empty/template-only. Use --skip-rca to bypass (logged).
-->

## Evolution

<!-- REQUIRED for arc-tagged build tasks (tags include arc:*). Captures how
     understanding evolved during build — what was learned that wasn't known at
     filing, what in the original plan no longer fits, what triggered pivots
     or new sub-tasks. Mandatory at slice boundaries (when applicable) and
     before --status work-completed.

     Origin: T-1717 grill Q4 — "the understanding of what we need and want
     evolves with the process of materialisation." Structural counter to §ACD:
     spec-vs-build divergence is logged as soon as it happens, not lost as
     folklore.

     Format (one entry per slice boundary or significant insight):
       ### YYYY-MM-DD — [topic]
       - **What changed:** [what we learned that we didn't know at filing]
       - **Plan impact:** [what in the plan no longer fits]
       - **Triggered:** [new sub-task / pivot / scope cut, with task ID if filed]

     The completion gate (T-1718) blocks --status work-completed when this
     section exists but is empty/template-only. Use --skip-evolution to bypass
     (logged Tier-2). Non-arc tasks may leave this empty.
-->

## Decisions

<!-- Record decisions ONLY when choosing between alternatives.
     Skip for tasks with no meaningful choices.
     Format:
     ### [date] — [topic]
     - **Chose:** [what was decided]
     - **Why:** [rationale]
     - **Rejected:** [alternatives and why not]
-->

## Decision

<!-- Filled at completion of inception tasks via:
     fw inception decide T-XXX go|no-go|defer --rationale "..."

     For non-inception tasks this section is ignored. Kept in template
     so `fw inception decide` (lib/inception.sh) finds the anchor heading
     without auto-creating; T-1832 added auto-create as fallback for
     legacy tasks lacking this section. -->

**Verification-level findings:**

  1. **empty-output-success** (partial, heuristic) @ Verification:line 19
     - evidence: `ls .context/episodic/T-1845.yaml .context/episodic/T-1846.yaml .context/episodic/T-1847.yaml .context/episodic/T-1858.yaml .context/episodic/T-1859.yaml .context/episodic/T-1860.yaml .context/episodic`
