Debug mode: enabled Effort study: railspike-effort / v3/qdb_rebuild_scope; ledger Extended estimates: enabled
Cycle estimate: 0.85
Entry: Step 3 approved, 2026-10-30 UTC; branch feature/bounded-tag-pages; planning commit 08dcb973. Original baseline 0392dd59c0646bebc37042455ecaccf825b13889, v1/B/R1/P2 and single exposed Codex rater retained. Step 3 projection 0.85 reaffirmed before implementation; original stage work S1–S6 0.20/0.12/0.12/0.18/0.15/0.14, non-additive. Scope and verification per approved plan. Measured labor unknown; production host acceptance pending. Unrelated draft audits and ledger entries excluded from commits.

Stage 1 - Live bounded tag pages
Original estimate: 0.20
Retrospective stage work: 0.20
Changes: TagPage selects eligible IDs before hydrating 25 rows; controller/route/template use native page links. Schema 38 to 39, unchanged tables with new query contract and concept documentation.
Verification: TagPaginationTest 2/2 (legacy membership parity, normal page/unknown tag, prior-version startup rebuilding before query); existing mixed-case tag smoke 1/1; isolated ./v3 rebuild succeeded through promotion. Initial fixture missed required reply_count; corrected test fixture and reran successfully. Whitespace checked.
Notes: Original scope/estimate unchanged; traversal, serving, offline and resource acceptance belong to later stages. Production host unverified. No dependencies added.

Stage 2 - Complete traversal and recovery
Original estimate: 0.12
Retrospective stage work: 0.12
Changes: Locked in the adapter/controller recovery contract with forward/back traversal, deleted anchors, changed activity, mixed-case cursor URLs, malformed/oversized/array/foreign-tag positions and empty-page restart tests. Stage 1 commit: fface7d9.
Verification: TagPaginationTest 4/4; all 65 eligible roots traverse in 25/25/15 pages exactly once and reverse correctly. Invalid/exhausted positions show First page without silently showing initial results.
Notes: Existing Stage 1 primitives satisfy these cases; no duplicate paginator added. Original scope/estimate unchanged; no production acceptance claimed.
— Codex · 2026-10-30 UTC
Stage 3 - Static and runtime serving
Original estimate: 0.12
Retrospective stage work: 0.12
Changes: Added actual release/frontend tests for QDB and forum profiles; documented bounded tag artifacts. Existing query bypass and static enumeration already satisfy the contract, so no replacement routing introduced. Stage 2 commit: c076581a.
Verification: 2/2 focused tests pass: fresh full release, mixed-case first route served statically, cursor route bypasses a sentinel first-page artifact, shared refresh retains tags, and existing failed-build recovery keeps the active release.
Notes: Original scope/estimate unchanged. Publication is verified locally with fixtures; live host remains pending.

Stage 4 - Offline saved tag pages
Original estimate: 0.18
Retrospective stage work: 0.18
Changes: Saved tag cards paginate in groups of 25 using native navigation classes, snapshot/tag-scoped positions, explicit foreign/stale/online recovery and popstate handling. Cache revision 14 to 15 delivers the updated reader without changing snapshot schema/generation. Stage 3 commit: 1f6ee8b5.
Verification: Offline presentation/worker/profile tests 25/25 plus new saved-tag regression 1/1; 65 saved matches traverse and reverse, changed membership/generation/tag and malformed/online positions reject without rendering unrelated cards. JavaScript syntax passed.
Notes: Original scope/estimate unchanged. Existing saved grouping remains; this stage bounds rendered cards, not snapshot generation. Full browser offline/reconnect evidence belongs to Stage 6.
— Codex · 2026-10-30 UTC
Stage 5 - Memory and incident regression
Original estimate: 0.15
Retrospective stage work: 0.15
Changes: Added isolated real-route/24-tag artifact resource fixtures and repeatable scaling/maximum-record tests. Measurements retain dimensions and limitations. Stage 4 commit: 70a4f1b1.
Verification: Resource test plus tags-index regressions and normal static-command smoke 4/4. All 1000/10000/40000 samples peak at 6 MiB under 32 MiB public/64 MiB artifact ceilings; exact-limit 16 MiB record plus 24 ordinary records peaks at 38 MiB under 128 MiB. Every tag artifact contains at most 25 cards. Initial fixture assertion assumed quote-card markup; corrected to the existing tag page's thread-card presentation and reran.
Notes: Original scope/estimate unchanged. Hydration/output bounded; SQLite candidate examination not instrumented and may scale with corpus. Legacy index failure reproduced in predecessor fix; current index and first-tag paths both exercised. Live failing tag is unknown, production retry pending; no full-scale build capacity claim.

Stage 6 - Verification checkpoint before requested merge
Original estimate: 0.14
Status: In progress; no retrospective assessment or completed-cycle claim. Request: User explicitly requested merge and push now, then continued testing. This authorizes an early integration checkpoint before Stage 6 completion; remaining verification and corrective work continue afterward. Changes: Added real-browser fixture and pagination flow covering native online and service-worker offline navigation. Verification so far: Browser online checks pass with JavaScript disabled/enabled, keyboard, history and failed-navigation retry; 16 themes at phone/desktop pass overflow and pagination stability checks. Real-worker offline check is still running. Stages 1–5 remain locally verified; production host recovery and full-suite results are not claimed. Next: Complete offline/browser checks, fix findings, finish catalog/concepts/ledger and final focused regression evidence. Unrelated audit drafts remain outside integration.

Stage 6 - Completed UI, catalog and operator handoff
Original estimate: 0.14
Retrospective stage work: 0.16
Changes: Completed catalog/outcome documentation and browser acceptance. Dedicated fixture router now serves the favicon like a normal static web server; added worker-readiness timeouts. The initial test router's favicon 404 prevented installation, not a product pagination failure. Stage 5 commit: 43e1c196; explicitly requested early merge/push checkpoint c4933cc5 is preserved.
Verification: Final focused PHP/Node-backed suite 63/63; real Chromium online JS-off/JS-on keyboard, all boundaries, reload/history, invalid-position recovery and failed-request retry; shared pagination under 16 theme styles at phone/desktop passes long-content overflow and settled-layout stability. Real installed worker verifies online-position rejection offline, saved 25/25/15 traversal, reload/Back, and reconnect-to-live recovery. Existing tests cover missing saved content, stale snapshot fingerprints and malformed cursors. Schema startup and isolated CLI rebuild passed earlier; local full static builds and failed-candidate recovery passed. Documentation paths and whitespace checked.
Notes: Recovery copy is essential and limited to failed positions; no explanatory UI added elsewhere. Dependency delta zero. No full-suite, physical-device, production PHP 8.3 or deployment acceptance claimed. Original stage estimate retained; separate retrospective 0.16 reflects fixture diagnosis, not measured labor.
Closeout
Retrospective cycle scope: 0.85
Status: All six stages complete locally. Original projection 0.85 and baseline/v1/B/R1/P2 retained; stages original 0.20/0.12/0.12/0.18/0.15/0.14 and retrospective 0.20/0.12/0.12/0.18/0.15/0.16 are separate non-additive judgments. Measured work unknown; maintainer comfortable-fit/acceptance pending, no accepted-outcome increment.
Delivered: Catalog plus all-site bounded tag browsing, native traversal/recovery, static first-page serving, offline saved pagination and schema 39 startup recovery. No optional prebuild policy or selective trust derivation. Planning 08dcb973, S1 fface7d9, S2 c076581a, S3 1f6ee8b5, S4 70a4f1b1, S5 43e1c196; S6 early integration c4933cc5 followed by this closeout commit. User authorized merge/push before final testing; implementation is already on origin/main, with verification closeout to follow.
Production recovery: Not verified. After normal deployment, run the original ./v3 build-static with unchanged settings at /home/qdb/v3, require all four phases and check tag/news first/later pages. Preserve the exact next failure if a different known allocation problem appears. Local tag-phase results are not a guarantee for the entire production corpus or every maximum-record distribution.

User-reported host recovery — 2026-10-30 UTC
User reports the build worked and activated release /home/qdb/v3/state/static_html/releases/release-20261030201011-af62aa46 in 314.961 seconds, producing 5253 HTML files and 53 assets. This supplies production build/activation evidence from the operator, not agent-observed execution or separate published pagination/browser verification. Runtime optimization now has a distinct proposed cycle, v3/qdb_build_time. Maintainer comfortable-fit study judgment remains unspecified; do not infer it from successful execution.
