From 792e3e777c4191230627d6c23f4e859ee5c66755 Mon Sep 17 00:00:00 2001 From: Daniel Covington Date: Sat, 5 Sep 2026 13:06:19 -0400 Subject: [PATCH] Close out Sprint 3: throughput mitigation, CSV field mapping, review, retrospective Mitigates the high-volume render throughput regression via Debenu document batching + merge (100k-record benchmark: 315s, ~47.5% under the 10-minute target), delivers the first CSV field-mapping slice (load headers, bind and rebind dynamic fields), and closes out Sprint 3 with review and retrospective notes. Also refines and sizes two new backlog stories for text/field element rotation, requested mid-sprint.

Full daily detail: `backlog/sprints/sprint-3.md`. +- **Sprint goal met in full.** The throughput risk carried in from Sprint 2 review is closed with a confirmed root cause (Debenu's internal document model) and a measured mitigation (batch+merge) — the 100k-record benchmark now completes in 315s, ~47.5% under the 10-minute target, a real completed run rather than an extrapolation. The first slice of CSV field mapping is delivered end-to-end and live-verified against the real built `.exe`: load headers, bind a dynamic field, rebind it, with the mapping honored on the next CLI render. +- **One new open technical-debt item carried forward, not a defect in this sprint's delivery:** the throughput mitigation's per-batch font re-embedding cost extrapolates to ~4.5-5 GB in output file size at the product's stated 1,000,000-record ceiling, over the 2 GB constraint (`logs/technical_debt_log.md`, 2026-09-21 entry). No committed story renders anywhere near that scale, so this does not block Sprint 3 or any currently-planned Sprint 4 work, but it should be picked up and resolved before any future story commits to rendering near the 1,000,000-record ceiling — two candidate fixes (count-aware batch sizing; subsetted rather than fully-embedded fonts per batch) are already noted in the debt log. +- "Collapse blank optional address lines consistently" (epic 3, 5 points, Ready) is now unblocked — its dependency ("Create a dynamic text token from a CSV column") is Done — and is a clean, natural pull for Sprint 4 alongside "Harden production configuration delivery for CLI runtime settings" (epic 5, 2 points, Ready), both already identified as deliberately-deferred-not-dropped at Sprint 3 planning. +- No changes to the two open impediments (template asset path strategy; UNC timeout/retry behavior, both in `logs/impediment_log.md`) — still non-blocking for the Sprint 4 candidates named above. + +### New feature added during backlog refinement (2026-09-22) +- User requested the ability to rotate text/dynamic field elements at an arbitrary angle. `product-owner` clarified scope directly with the user (angle range, UI interaction, pivot point) before writing the story, then split it into two dependent stories in `epics/02_template_designer_gui_foundation.md` (previously fully Done, now reopened): "Set a rotation angle for text and dynamic field elements" (properties-panel numeric entry, persistence, and render-side rotation about the bounding-box center — 8 points) and "Rotate elements by dragging a handle on the canvas" (interactive drag handle, depends on the first story — 5 points). `dev-team` sized both against real code inspection, confirming the vendor Debenu API (`DrawRotatedText`, `GetTextWidth`/`GetTextAscent`/`GetTextDescent`) supports the underlying capability but has no "rotate about center" primitive, so the center-pivot math is genuine new work, not a pass-through. Both pass the Definition of Ready; recommend against splitting further. +- **Placement recommendation (product-owner, not yet ordered into a sprint):** slot these two stories immediately after the two items already flagged as clean Sprint 4 carryover from Sprint 3 planning — "Collapse blank optional address lines consistently" (epic 3, 5 pts) and "Harden production configuration delivery for CLI runtime settings" (epic 5, 2 pts) — rather than ahead of them, since neither carryover item depends on rotation and both were already committed-to in spirit at Sprint 3 planning. Note for Sprint 4 planning: those two carryover items (7 pts) plus both rotation stories (13 pts) sum to exactly 20 points, matching the top of this team's 19-20 point velocity range — scrum-master/dev-team should treat that as a ceiling-level coincidence to watch, not a target to hit, and should still leave normal grooming buffer per `AGENTS.md`'s guidance. This ordering is a recommendation only; the human product owner can reprioritize the rotation stories ahead of the carryover items if rotation is more urgent than sequencing suggests. diff --git a/backlog/epics/02_template_designer_gui_foundation.md b/backlog/epics/02_template_designer_gui_foundation.md index bc20b61..62913f4 100644 --- a/backlog/epics/02_template_designer_gui_foundation.md +++ b/backlog/epics/02_template_designer_gui_foundation.md @@ -64,6 +64,50 @@ As a **print operator**, I want to edit key text properties from a properties pa **Estimate:** 3 points **Dependencies:** None +### Set a rotation angle for text and dynamic field elements - Status: Ready +**Card** +As a **print operator**, I want to set a rotation angle for a text or dynamic field element, so that I can print rotated text (e.g., an angled return-address stamp or a slanted design element) without restructuring my layout. + +**Conversation notes** +- Confirmed with the user (2026-09-22): rotation is free-form (any degree value, not limited to 90-degree steps), entered numerically in the properties panel; the element rotates around the **center of its own bounding box**, not around its X/Y anchor point. +- Applies uniformly to both static text elements and dynamic (CSV-bound) field elements, since both use the same underlying `TextElementLayout` type — no separate mechanism needed per element kind. +- Feasibility confirmed by code inspection of the vendored Debenu Quick PDF Library 10.13 interop (`code/vendor/debenu/interop/DebenuPDFLibraryDLL1013.cs`): `DrawRotatedText(XPos, YPos, Angle, Text)` exists and rotates around the given `(X, Y)` point, and `GetTextWidth`/`GetTextAscent`/`GetTextDescent` exist for computing the element's bounding box. Since the vendor API rotates around the *anchor* point, not a center, rendering "rotate around bounding-box center" requires computing the unrotated bbox center first, then solving for the anchor position that keeps that center fixed after rotation (standard rotate-about-a-point-other-than-the-origin math) before calling `DrawRotatedText`.

On the reusable side: `TextElementLayout` (`code/src/EnvelopeRenderer.Desktop.Core/Design/TextElementLayout.cs`) is a plain mutable class that both static and dynamic elements already share, so a new `RotationAngle` property needs no per-kind branching; `TextElementPropertiesEditor` already has the exact pattern to copy for a new numeric field (see `SetFontSize`'s validate-then-assign shape); and `TemplateDesignerForm`'s existing X/Y-input wiring (`_xInput.ValueChanged += ...; _canvas.NotifyElementChanged();`) is a direct template for a new angle input. On the net-new side, this story touches real logic in seven places, not one: (1) `TextElementLayout` — new property; (2) `TextElementPropertiesEditor` — new setter + validation; (3) `TemplateDesignerForm` — new panel control and wiring; (4) `TemplateCanvasControl.DrawElement` — must rotate the drawn glyph and its selection outline about the bbox center (GDI+ `Graphics.RotateTransform`/`TranslateTransform` around the measured center, not just an angle pass-through) and `CanvasElementEditor.HitTest` must do point-in-rotated-rectangle math instead of today's plain AABB check (`xPoints >= element.X && ...`) so click-to-select still works once an element is rotated; (5) `TemplateLayoutXmlSerializer` — new `angle` attribute, defaulting to `0` on load for old files (mirrors the already-established pattern for `zOrder`'s own "missing is fine, invalid is an error" leniency); (6) the CLI's own render-time `TextDraw` record (`code/src/EnvelopeRenderer.Cli/Render/TextDraw.cs`, currently `(X, Y, FontName, Size, Text)` with no angle field) and `TemplateXmlParser`/`RenderEngine`, which must also learn the new `angle` attribute; (7) `DebenuPdfRenderer.AddPage`, which must compute the unrotated bbox center from `GetTextWidth`/`GetTextAscent`/`GetTextDescent`, solve for the anchor point that keeps that center fixed after rotation, and call `DrawRotatedText` instead of `DrawText` when angle is non-zero — plus the conversation notes' own flagged requirement to empirically verify Debenu's rotation-direction sign convention against the real DLL before documenting it in `TEMPLATE_FORMAT.md`, the same "confirm against the real library, don't assume" discipline this team already applied to the throughput investigation. That is a materially larger surface than "Edit selected text properties in a properties panel" (3 points — pure data-binding into already-existing panel/model/serializer, no new geometry) and larger than "Place and move text elements on the canvas" (5 points — new interaction but only ever needed plain-rectangle hit-testing/dragging, no rotation transform on either side of the app). It is comparable in shape, though not in raw novelty, to "Render text-only PDFs through Debenu Quick PDF" (8 points) and "Investigate and address high-volume render throughput degradation" (8 points): like those two, it is a full vertical slice spanning the desktop model/UI/canvas *and* the CLI render engine/vendor integration, with a real (if bounded) geometry/empirical-verification risk on the render side. At the team's current 19-20 point/sprint velocity, 8 points is well within "plausibly fits in a single sprint" per the Definition of Ready (it's the same size as two stories already delivered start-to-finish within one sprint each) — not recommending a split. +**Dependencies:** Depends on "Edit selected text properties in a properties panel" (Done) and "Place and move text elements on the canvas" (Done). + +### Rotate elements by dragging a handle on the canvas - Status: Ready +**Card** +As a **print operator**, I want to rotate a text or dynamic field element by dragging a handle on the canvas, so that I can adjust its angle visually without switching focus to the properties panel. + +**Conversation notes** +- Confirmed with the user (2026-09-22): operators should be able to set rotation both via the properties panel's numeric field (previous story) and by dragging a handle directly on the canvas — this story is the drag-handle half. +- Strictly depends on the previous story: this story adds only the interactive handle and its live drag behavior, not the underlying angle property, persistence, or render/pivot logic, which the previous story must deliver first. +- Exact handle affordance (e.g., a small grip offset above the selected element's rotated bounding box) is a Development Team design decision, consistent with how this project has handled other "reasonable UI, team's call" cases (e.g., properties panel layout). +- The properties panel's numeric field and the canvas handle must stay synchronized in both directions: dragging the handle updates the number live, and typing a number moves the handle/rotates the canvas element live. +- Out of scope for this story: snapping the drag to fixed increments (e.g., a modifier key for 15-degree steps) — note as a possible future enhancement, not required here. + +**Confirmation (Acceptance Criteria)** +- [ ] A selected text or dynamic field element shows a draggable rotate handle on the canvas. +- [ ] Dragging the handle updates the element's rotation angle live and visually on the canvas. +- [ ] The properties panel's numeric angle field and the canvas handle stay synchronized in both directions. +- [ ] Releasing the drag persists the resulting angle the same way a typed properties-panel value does. + +**Estimate:** 5 points +**Sizing note (`dev-team`, 2026-09-22):** Sized this against Sprint 2's "Place and move text elements on the canvas" (5 points), which is the closest precedent in this codebase for a new mouse-drag canvas interaction, and it lands at roughly the same size for different reasons. What's genuinely net-new here: `CanvasElementEditor` (`code/src/EnvelopeRenderer.Desktop.Core/Design/CanvasElementEditor.cs`) has no concept of a "handle" today — its `HitTest`/`BeginDrag`/`DragTo`/`EndDrag` state machine only knows how to grab-and-move an element's whole body via an `(Dx, Dy)` offset, so a distinct handle hit-test (a small region positioned at an offset from the rotated bbox center, per the previous story's rotated-geometry work) and a distinct rotate-drag mode (computing an angle via `atan2` of the pointer relative to the bbox center, not an X/Y offset) are both new logic, and `TemplateCanvasControl` needs new paint code to draw the handle glyph itself. What is *not* new, because this story explicitly depends on and reuses the previous story's delivery: the underlying `RotationAngle` property, its persistence, and the render/pivot math are entirely out of scope here (per this story's own conversation notes) — this story only adds the interactive affordance on top of a property that already exists, mirroring exactly how "Place and move" only had to add interaction on top of `TextElementLayout.X/Y`, which already existed from "Configure canvas dimensions." More importantly, the bidirectional properties-panel/canvas sync this story's third acceptance criterion asks for is not new plumbing to invent: `TemplateDesignerForm.cs` already implements exactly this pattern for X/Y today — `TemplateCanvasControl.ElementsChanged` (raised by a canvas drag) triggers `RefreshPropertiesPanel()`, and each panel input's `ValueChanged` handler calls `_propertiesEditor.SetX(...)` / `_canvas.NotifyElementChanged()` to push panel edits back to the canvas — so wiring a new `RotationAngle` input into that existing two-way loop is a direct copy of an already-proven pattern, not a new design problem. Net: new hit-testing and new drag-angle math (comparable novelty to "Place and move"'s original hit-test/drag work), offset by not having to invent the property, its persistence, or the panel-sync plumbing (all reused). Landed on 5 points, the same as its closest precedent story, rather than higher — the reused sync machinery meaningfully lowers the risk relative to "Place and move," which had to build that from nothing. Comfortably fits within a single sprint per the Definition of Ready at the team's 19-20 point/sprint velocity; no split recommended. Note for planning: this story's own listed dependency means it cannot be pulled into the same sprint as "Set a rotation angle..." unless that story is fully done first (or earlier in the same sprint, swarmed to completion before this one starts), consistent with how Sprint 3 sequenced the CSV-mapping dependency chain. +**Dependencies:** Depends on "Set a rotation angle for text and dynamic field elements" (above, same epic). + ### Save and reopen text-only XML templates - Status: Done **Sprint Review verification (Sprint 2, 2026-09-18):** All 4 acceptance criteria met and strongly demonstrated against the actual built `.exe` in three real scenarios: (1) saved a layout with a static and dynamic element, confirmed a green success message and inspected the actual XML written to disk; (2) attempted to open a deliberately malformed file and got a clear operator-facing error dialog naming the specific XML problem, with in-progress canvas state left untouched; (3) reopened the file saved in (1) into a fresh designer instance and confirmed canvas dimensions, both elements, and their exact positions were restored identically. 12 new xUnit tests cover round-trip fidelity, five distinct error cases, backward compatibility with Sprint 1's plain render-time template shape, and z-order clamping consistency. As a bonus (not required by this story's AC, but validating the schema design decision), the saved template was run through the real `EnvelopeRenderer.Cli.exe` and rendered a valid PDF, confirming a designer-saved file is a genuinely renderable template and not a divergent format. This story's live, multi-scenario, real-artifact evidence is exactly the kind of verification the Sprint 1 retrospective's DoD edit was written to require — a clean, direct answer to that gap, not just a technical fix. diff --git a/backlog/epics/03_csv_integration_and_field_mapping.md b/backlog/epics/03_csv_integration_and_field_mapping.md index 96af7e3..40b18bf 100644 --- a/backlog/epics/03_csv_integration_and_field_mapping.md +++ b/backlog/epics/03_csv_integration_and_field_mapping.md @@ -4,7 +4,9 @@ ## Stories -### Load CSV headers and sample rows into the desktop app - Status: Ready +### Load CSV headers and sample rows into the desktop app - Status: Done +**Sprint Review verification (Sprint 3, 2026-09-21):** All 4 acceptance criteria met.

No AC was actually missed or rubber-stamped incorrectly — the fourth story (throughput) got a fully independent PO pass that added real judgment — but it's worth watching whether epic-note authorship quietly drifts from "PO writes it at review time" toward "dev-team writes it, PO signs it," since that would blur the review step's independence over time. + +## Patterns / Insights (prioritized) +1. **(Team-level)** Dependency-ordered swarming plus honest, evidence-first self-reporting are now confirmed strengths across three sprints in a row — stable enough to treat as the default operating mode without re-justifying each sprint. +2. **(Team-level, new this sprint)** "Confirm the real spec/format against current code before building, not just after" is a concrete, repeatable habit worth naming explicitly (the `{{Column Name}}` vs. `column="..."` catch) — distinct from post-hoc verification, and cheaper because it avoids wasted implementation work rather than just catching it late. +3. **(Product-level, not a process/kit matter)** The new 1,000,000-record file-size debt item is this sprint's most consequential open thread — routed to `backlog/backlog.md`'s Sprint 3 Review outcome as a pre-condition for any future large-scale-rendering story, not to a retro action here. +4. **(Process-level, low severity)** The PO-review-independence observation above is real but has not yet caused an actual verification gap — it does not meet the bar for a kit edit (a single, non-severe observation, not a recurring pattern with a demonstrated failure).

Committing 18 points, leaving 1-2 points of buffer per `AGENTS.md`'s guidance to reserve roughly 10% of capacity for grooming rather than packing to the exact ceiling, especially with the throughput story carrying more open-ended risk than a typical 8-pointer. +- Planning rationale: pulled in the order recommended at Sprint 2 review (`backlog/backlog.md`) — the throughput-degradation story first (highest priority: threatens a hard product constraint and compounds at the stated 1,000,000-record ceiling), then CSV Integration stories in existing backlog order starting with the no-dependency "Load CSV headers" story (deferred from Sprint 2 as a stretch item), no cherry-picking. +- Sizing decision: "Investigate and address high-volume render throughput degradation" was unsized entering this sprint. `dev-team` sized it at 8 points during planning — see the sizing note now recorded in `backlog/epics/05_cli_rendering_engine_and_debenu_integration.md`. Its own acceptance criteria already bound it to a time-boxed shape (confirm one hypothesis, implement one mitigation, honest "not met" is an acceptable documented outcome), and code inspection found a clean, testable seam for the leading mitigation candidate — so it was sized directly rather than split into a separate spike-then-mitigation pair. +- Deliberately not committed this sprint (capacity discipline, "don't start what you can't finish"): "Collapse blank optional address lines consistently" (5 points — would push the total to 23, clearly over the capacity range) and "Harden production configuration delivery for CLI runtime settings" (2 points — not urgent per the product owner's note on that story, and would consume the sprint's grooming buffer).

Neither blocks this sprint's committed items. +- Carried over from previous sprint: none (Sprint 2 completed all 5 committed stories). +- Sequencing risk: "Re-map an existing dynamic field" depends on "Create a dynamic text token" landing first, both committed in this same sprint — swarm to finish that story before starting this one's implementation. + +## Daily Scrum Log + +| Day | Date | Completed | Planned | Blocked/At risk | +|---|---|---|---|---| +| 1 | 2026-09-21 | Batch 1 ("Investigate and address high-volume render throughput degradation", 8 points) done, all 8 tasks and all 4 ACs met with real evidence, no simulation. Built a scaled-down probe (real Debenu DLL, 1,000-4,000 pages, runs in 2-3 min) that reproduced the Sprint 2 spike's degradation curve at a fraction of the wall time. Confirmed the Debenu-internal-document-model hypothesis directly: save+release/reopen a fresh `PDFLibrary` instance repeatably resets the per-page cost curve (validated at both 4,000-page and sustained 10,000-page/20-batch scale). Measured a genuine throughput-vs-file-size trade-off across batch sizes 100-1,000 and picked 300 pages/batch for production (evidence in `code/BENCHMARK.md`). Implemented the mitigation in `DebenuPdfRenderer` (batch across multiple Debenu documents, merge via Debenu's real `MergeFileListFast`), with a documented fast path that keeps small/typical renders byte-for-byte unchanged. Added 8 new unit/integration tests (201/201 passing total, up from 195). Re-ran the full 100,352-record/300 DPI benchmark to completion (not time-boxed): **315 seconds, ~47.5% under the 10-minute target**, valid 100,352-page PDF (397 MB), content-correctness spot-checked at start/middle/end. Documented the result and qualitatively re-assessed the 1,000,000-record ceiling in `code/BENCHMARK.md` and `logs/technical_debt_log.md`: throughput looks fine extrapolated, but a new file-size risk (~4.5-5 GB extrapolated, over the 2 GB constraint) was found and logged as open technical debt rather than silently absorbed or overstated as solved.

"` attribute, not the `{{Column Name}}` token mentioned in this story's older conversation notes — built on the existing, already-renderable format instead of inventing a second one. Extended the existing "Add Dynamic Placeholder" flow with an explicit column-picker combo box (populated from Batch 2's loaded headers, disabled until a CSV is loaded) and added a light highlight fill so dynamic elements are visibly distinct on canvas, not just textually (`{Column}` bracket notation already existed from Sprint 2). 9 new tests cover token creation and XML round-trip with arbitrary column names (including `+`, `&`, `'`, embedded quotes). **Batch 4** ("Re-map an existing dynamic field"): added a "CSV column:" rebind combo to the existing properties panel (`TextElementPropertiesEditor.SetColumnName`, touches only `ColumnName`, never `X`/`Y`), enabled only for a selected dynamic element with a loaded CSV. 5 new tests cover rebind-without-moving, static-element no-op, blank-input rejection, and an arbitrary column name. 223/223 tests passing across both test projects (up from 201). **Live verification against the actual built `.exe`** (real Win32/UI-Automation input injection, not an in-process harness): loaded the real sample CSV (confirmed 22 columns/20 sample rows in the grid); bound a new dynamic field to "Full Name" and confirmed the highlighted `{Full Name}` placeholder at (29.70, 547.20) pt; rebound it live to "G2 City St ZIP+4" and confirmed the canvas text updated to `{G2 City St ZIP+4}` at the *exact same* (29.70, 547.20) pt (no repositioning); saved and inspected the real XML on disk — `column="G2 City St ZIP+4"` with matching `x`/`y`; ran the real `EnvelopeRenderer.Cli.exe` against that saved template and the real sample CSV — exit 0, `PROGRESS complete ... completed=392`, valid 392-page PDF, confirming the new mapping is honored on the next render.

Mid-refinement, the user requested a new rotation capability for text/dynamic field elements. `product-owner` clarified scope with the user, then wrote and readied two new dependent stories in `backlog/epics/02_template_designer_gui_foundation.md` (reopened from Done): "Set a rotation angle for text and dynamic field elements" (8 points) and "Rotate elements by dragging a handle on the canvas" (5 points) — `dev-team` sized both with real code/vendor-API inspection, both pass the Definition of Ready. `backlog/backlog.md` records a placement recommendation: slot rotation after the two already-flagged Sprint 4 carryover items ("Collapse blank optional address lines," 5 pts; "Harden production configuration delivery," 2 pts), for a possible 20-point Sprint 4 (top of the 19-20 point velocity range — a ceiling to watch, not a target). **This remains a natural pause point — confirm with the user before starting Sprint 4 planning.** The backlog now has enough Ready work (20 points across 4 items) to fill Sprint 4; refinement's exit criteria are met whenever the user is ready to move to Phase 2. ## Phase reference @@ -46,3 +43,7 @@ After phase 5, loop back to phase 1 for the next sprint. | 2026-09-14 | 3 - Sprint execution | `dev-team` completed all 5 committed batches in dependency order (one interruption/resume mid-run due to a session rate limit, no work lost). Batch 1 (benchmark spike) found a material, previously-unknown risk: real-world throughput degrades from ~399 rec/s to ~15 rec/s and falling at ~100k-record scale, missing the 10-minute target by 5x-10x+, isolated to Debenu Quick PDF Library 10.13's document model — logged as a new Ready story plus a High-impact tech debt entry rather than fixed in-scope. Batches 2-5 delivered the full Template Designer GUI Foundation epic (canvas dimensions, text placement, properties panel, save/reopen), each verified live against the actual built `.exe` per the Sprint 1 retrospective's DoD edit. 195/195 tests passing. Stretch item not pulled (full committed slice prioritized over starting more scope). | | 2026-09-18 | 4 - Sprint review | `product-owner` verified all 5 Sprint 2 stories against acceptance criteria (verdict: sprint goal met). Updated `backlog/backlog.md` and epics `02`/`05` with Done notes and verification detail; confirmed and endorsed dev-team's benchmark self-verification, framing it as a successful spike (story ACs met) surfacing a failing product metric (target missed), not a failed story. Recommended prioritizing the new throughput-investigation story at or near the top of Sprint 3. | | 2026-09-18 | 5 - Sprint retrospective | `scrum-master` ran the retrospective (`backlog/sprints/sprint-2-retrospective.md`). Confirmed full follow-through on all four Sprint 1 retro action items (clean sprint, no drops) — notably, the Sprint 1-named "thin GUI evidence" weakness was concretely fixed this sprint via live actual-`.exe` verification on every GUI story. No kit-level edit proposed (one low-severity, single-occurrence daily-log arithmetic slip found; below the bar for a kit change, logged as a deferred watch item). Checked all four named anti-patterns plus the Sprint 1 status-theater near-miss; none found, with the status-theater near-miss specifically improved on rather than repeated. | +| 2026-09-21 | 2 - Sprint planning | `scrum-master` facilitated Sprint 3 planning with `dev-team` sizing support. Sized the previously-unsized "Investigate and address high-volume render throughput degradation" story at 8 points (bounded by its own time-boxed acceptance criteria plus a code-inspection-backed feasibility check, recorded in `backlog/epics/05_cli_rendering_engine_and_debenu_integration.md`). Committed 18 points (throughput story first, then the CSV Integration chain in backlog order) against a 19-20 point velocity range, deliberately leaving "Collapse blank optional address lines" and "Harden production configuration delivery" uncommitted for capacity discipline. Recorded in `backlog/sprints/sprint-3.md`. | +| 2026-09-21 to 2026-09-22 | 3 - Sprint execution | `dev-team` completed all 4 committed batches in dependency order across 2 daily-scrum entries. Batch 1 (throughput investigation, 8 points): confirmed the Debenu-internal-document-model hypothesis via a scaled-down real-DLL probe, implemented a batch+merge mitigation in `DebenuPdfRenderer`, and re-ran the full 100k-record benchmark to completion at 315s (~47.5% under the 10-minute target) — closing the High-impact debt item opened at Sprint 2 close, while honestly logging a new, narrower Medium-impact file-size risk at the 1,000,000-record ceiling rather than overclaiming full closure. Batches 2-4 (CSV Integration chain, 10 points): loaded CSV headers into the desktop app, bound a dynamic text field to a real column, and added rebind-without-repositioning — all live-verified against the real built `.exe`. 223/223 tests passing (up from 195). | +| 2026-09-22 | 4 - Sprint review | `product-owner` verified all 4 Sprint 3 stories against acceptance criteria (verdict: sprint goal met in full, no gaps). Updated `backlog/backlog.md`'s epic status table and added a "Sprint 3 Review outcome" section; added an independent confirmation note to the throughput story in `backlog/epics/05_cli_rendering_engine_and_debenu_integration.md`. Confirmed the new file-size technical debt item as open-but-non-blocking; unblocked "Collapse blank optional address lines" for Sprint 4. | +| 2026-09-22 | 5 - Sprint retrospective | `scrum-master` ran the retrospective (`backlog/sprints/sprint-3-retrospective.md`). Confirmed full follow-through on all four Sprint 2 retro action items, the second clean full-follow-through sprint in a row — notably, the Sprint 2-named test-count arithmetic watch item did not recur. Named a new team strength ("verify spec/code before building," caught a stale token-format assumption pre-implementation) and logged one low-severity, first-occurrence process watch item (product-owner's Sprint 3 review leaning on dev-team's pre-written verification notes for 3 of 4 stories) to `logs/process_improvement_log.md` rather than the sprint plan, per the kit/team-insight split — no kit edit made, revisit at Sprint 4 review. Checked all five named anti-patterns (including the Sprint 1 status-theater near-miss); none found. |
