## Plan
- Job 2635: tender build for Liam's 1pm boss meeting — Hammond Canal Bridge FRP package re-issued by TCE direct (no Dec Projects).
- Deliverable: WBS + programme + methodology + manpower framework. Reprice off 90% DD drawings 2-3 days post-meeting.

## Sessions

### 09:30 — Cowork (executor) + Cowork (orchestrator separate chat) — 2635 tender build pack

Executor: Cowork session in `2635 — TCE Hammond Canal Bridge (Munmorah)/_AI-Outputs/`. Orchestrator: separate Cowork chat. Rocky pasted outputs between us at checkpoints.

**Initial brief:** lift 2602 v-CC rev3 as the spine for the boss meeting print pack. SAME-scope path. Run drawings analysis + grill validation in parallel.

**Phase 1 — BOQ delta check:** **SAME SCOPE.** BOQ `P424-HCB-BOQ-FRP-Package (4).xlsx` is bit-for-bit identical to the 2602 source BOQ. Same date (2025-12-11), same revision (A), same 24 priceable lines, same qty. The "(4)" is a download iteration, not a BOQ revision.

**Phase 2 — Drawings analysis:** 2602 was 3-sheet IFI sketch package. 2635 = 38-sheet NL251342 90% Detail Design set issued 01.05.26 by Northrop. Material design progression. 2602 carry-over RFIs status: (a) carriageway 8.2 vs 9.0 RESOLVED at 8.2 m, (b) bearings supply STILL OPEN, (c) thrie beam vs concrete barrier RESOLVED at thrie beam Low Performance Level, (d) Renderoc patch OBSOLETE (scope changed to saw-cut + new return wall). 7 NEW SCOPE items identified on S87/S88 not in BOQ (maintenance access slab + stairs, subsoil drain, cantilever return wall, concrete blinding, pedestrian safety rail, shotcrete batter [EXCL], chainlink mesh [EXCL]). Bearings spec upgraded 350×280×157 → 480×380×143 H, AS p/n 070909R.

**Phase 3 — Grill validation:** walked Q-A through Q-G against 2635 context. Most positions carry; ⚠️ CHANGED items captured (cross girder explicit, dowel spec, pile testing required, GPM stakeholder, B2 deck exposure). 15 NEW open RFIs raised.

**Phase 4 — Pricing core:** v1 lift at $416,738 ex GST (+2.2% vs 2602 anchor $407,870). Calibrated against Dec EE Genesis productivity figures (validated by Robert on 2602 QS call) re-rated to LFCS Rate Card V1.7 day rates ($85/$95).

**Orchestrator pushback (4 items):** reo productivity reconciliation (15 hrs/T fix-only vs concept-note 22-25 all-in — explained: line + prelims = 20.4 hrs/T effective all-in), GPM dual induction (Generator Property Management = power station asset owner, +$2k for second induction), 10% materials markup (line-by-line on LFCS-supplied materials only ~$625 total), 15 RFIs severity-tagged (4 BLOCKING, 8 INFORMATIONAL, 3 NICE-TO-HAVE).

**Phases 5/6/7 — Framework deliverables:** Methodology docx (9 sections, Rocky's voice, Big Slims system, 13-step construction sequence) + Programme PDF + JSX (Gantt W0-W19, critical path, 4 BLOCKING RFIs flagged at W1) + Manpower histogram xlsx + PDF (peak basis, 30% non-productive uplift, capped 15 men/day, peak W14 deck pour).

**Direction change — REPRICE not LIFT:** orchestrator pivoted late. $416,738 figure is REFERENCE ONLY — could be ±$50-100k. 2602 was priced off Plan + Super-T section. 90% DD requires full reprice. Pivot Phase 8: front cover removes $416k as headline, replaces with reprice framing ($407k 2602 anchor + $350-500k indicative range + 4 BLOCKING RFIs with $-swing). Methodology / Programme / Manpower stay as PRIMARY framework. Stage-by-stage pricing worksheet built (BLANK price columns + 2602 reference column) for Rocky's working tool — NOT for the meeting.

**Phase 8 — Boss Pack PDF (21 pages):** Cover + exec summary + repricing approach + inclusions/exclusions + risks register + drawing index + 15 RFIs full + methodology + programme + manpower. Sanitised — no internal cost basis / supervisor loading / redundancy % exposed.

**Phase 9 — Walkthrough cheatsheet:** updated boss Q&A with reprice framing. Q1 "What's the price?" → "Haven't priced it yet, 2602 was $407k off 3 IFI sketches, running stage-by-stage reprice off 38-sheet 90% DD over 2-3 days, headline range $350-500k." Plus full Q&A on geometry (deck thickness, carriageway, bearings p/n, pile sockets, etc.) for fluency demonstration.

### Decisions made
- **GO on SAME-scope path** (Phase 1 BOQ identical to 2602 confirmed).
- **Defensible-for-variations posture** preserved — Rate Card V1.7 day rates as submission AND variation basis.
- **Saw-cut canal wall (6.1.1)** EXCLUDED at submission per 2602 grill carry-over; now dimensioned on S05.01 (RL 3.550 full width) — available as VO if TCE reinstates.
- **NEW scope items on 90% DD** (maintenance access slab, subsoil drain, return wall, ped safety rail) carried as AVAILABLE AS VO at Rate Card V1.7 basis — not included in 24-line base bid.
- **Shotcrete batter + chainlink mesh safety barrier** EXCLUDED — specialist subbie scope.
- **Programme 13 wk LFCS scope** + ~4 wk TCE piles + handover = ~20 wk full.
- **Crew 6 men + 1 supervisor.** Day shift only.
- **REPRICE direction confirmed** — $416,738 reference only; submit number lands 2-3 days post-meeting from stage-by-stage worksheet.

### Blockers
None at end of session. Boss meeting ready.

### Insights worth keeping
- Bridge concept-note reo productivity 22-25 hrs/T benchmark is ALL-IN; LFCS line-item fix-only rates land 13-18 hrs/T + prelims supports = ~20 hrs/T effective. **Concept-note range should be updated to 20-25 hrs/T post-mortem.**
- "(4).xlsx" download artifact filenames don't mean Rev 4 — always check the date + rev in the title block.
- GPM = Generator Property Management is the asset owner on the former Munmorah Power Station site — separate from TCE. Affects induction cost + demolition methodology approval gate.
- Bearings supply RFI carried from 2602 — has been unresolved across two design issuances. Must close pre-submission.

### Action items
- [ ] Boss meeting today 1pm — present framework + reprice approach.
- [ ] Issue 4 BLOCKING RFIs to TCE immediately post-meeting (RFI-1 bearings supply, RFI-2 maintenance access slab scope, RFI-9 civil drawings, RFI-15 BOQ 9.2.2 wording).
- [ ] Stage-by-stage reprice 2-3 days post-meeting using `08-Stage-by-Stage-Pricing-Worksheet-2635.xlsx`.
- [ ] Update concept note `lfcs-standards/concepts/TfNSW-bridge-FRP-subcontract-pattern.md` reo productivity range from 22-25 to 20-25 hrs/T.
- [ ] Confirm bid-due date with TCE — currently placeholder W8 on programme.
- [ ] Per-job CLAUDE.md not yet created at 2635 root — need to scaffold (template at 2602's CLAUDE.md).

### Resume notes (if picked up later)
All deliverables in `_AI-Outputs/`. Primary: `08-Boss-Pack-Hammond-2635.pdf` (21 pages), `08-Stage-by-Stage-Pricing-Worksheet-2635.xlsx`, `09-Walkthrough-Cheatsheet.md`. Working files: `00-status.md` is the running log with all 5 checkpoints; `04-Tender-Summary-2635.xlsx` and `04-Rate-Buildup-2635-INTERNAL.xlsx` are REFERENCE ONLY (superseded by reprice plan). 2602 reference materials in `_AI-Outputs/_2602-reference/`.

### evening — claude-code-coo — Autonomous overnight session (sandbox build + 4 task packages)

Rocky handed off autonomous mode for 12-18 hours. Sandbox `C:\Users\mclou\ContractorOS-LFCS-Trial\` operates under plan-v0 → plan-v3 build cycle. End-state: 42-skill merged stack, all 3 regression gates clear, plan-v4 produced + halted at build, 4 task packages complete.

**Plan-v3 build closure (Wave 2 + Wave 3 + final gate):**
- Wave 2: 9 sub-agent invocations → 13 new skills (post-award delivery + commercial). Commits b415224 / c4f1905 / 3138541 / 612dfcc / ea78694 / adf1ecd / 6764fa9 / 4741305 / 19aa78e.
- Wave 2 regression gate: PASS — all 10 frozen 2602 outputs unaffected.
- Wave 3: 4 sequential skills (closeout + cross-job): lfcs-completions-requirements `ab88c6c`, lfcs-om-manual `7d22e2f`, lfcs-dashboard-builder `0a0e05e`, lfcs-notebooklm `cf295d3`.
- Final gate: PASS. 42-skill stack ready for migration. plan-v3 status flipped to `build-complete-migration-pending`.

**Task 1 — Hasibul-pattern absorption — plan-v4 written, build HALTED.** 10-pattern integration design at `_System/plan-v4-hasibul-absorption.md` (~9000 words). Per-pattern integration points + dependency DAG + topology map + regression risk + 8 integration questions + Rocky-impact analysis (5-axis forecast: P1 default-go alone removes 6-12 pauses per bid). 7 open questions for Rocky in §8: brand colour discrepancy (#D72229 vs existing #C80F2E), 10/11 folder numbering, override token for mandatory pauses, etc. **Build does not proceed until Rocky signals plan-v4 approved.** Commit `4a80787`.

**Task 2 — Self-improvement loop activated.** 4 commits. (1) `412588e` pricing-history seed — 15 records across 3 jobs grouped by element family (2602/2626 won-no-recon, 2635 Hammond budget anchor quoted; xlsx extracted via Python openpyxl); (2) `86279e4` lfcs-job-retrospective SKILL.md v1 — 8-Q retro + improvement-backlog queue + confidence-tier promotion logic; (3) `74db850` improvement-metrics.csv baseline row + improvement-cadence.md stub + improvement-backlog.md empty; (4) `3efaaef` status update.

**Task 3 — Learning package.** 8 commits — 6 modules + 1 A5 card sheet + status. Plain English for steel-fixer-turned-operator. `_System/learning-guide/`: 01-architecture-plain-english (vault/skills/library/Airtable analogies) · 02-per-skill-walkthrough (43 cards across 6 lifecycle groups) · 03-workflow-recipes (12 cookbook recipes — full tender / fast ROM / monthly CVR / variation / inbound PC / outbound PC / RFI / NCR / daily diary / weekly rollup / job retro / portfolio dashboard) · 04-glossary (~60 terms with construction analogies) · 05-failure-mode-field-guide (18 modes with diagnosis/recovery/prevention) · 06-extending-the-system · A5-reference-cards. Commits `53731b7` / `b1b7428` / `243dc20` / `8aed3a5` / `b9e0b64` / `e539e9b` / `24b0dd6` / `ef1f9dd`.

**Task 4 — Comparison fixture runs (PRIORITY deliverable).** 6 commits (4 sandbox + 2 HQ-Vault). Reference Pack (Hammond methodology v2 + 5 boss artefacts A1-A5 + 15 Hammond chat outputs + 2602 reverse-eng BOQ) mirrored into BOTH the sandbox 2602-fixture and the live HQ-Vault `Upcoming/2602 - Dec Projects - Munmorah Bridge/_Reference-Pack-2026-05-15/` for information parity. Mt Erin Rd 2640 (FTI FastTread stair install at 13 Mt Erin Rd Campbelltown) scaffolded in BOTH stacks — 11-section folder + CLAUDE.md v5 + 00-brief + README + FTI source PDFs renamed per convention. Comparison report at `_System/comparison-report-2026-05-15.md` (~6850 words, 12 sections + 2 appendices). Headline: **NEW stack wins 7-2-1 axes across both runs.** Run 1 (2602 re-price): User Pauses 24 OLD vs 25 NEW (OLD wins by 1), Wall Time 225 OLD vs 210 NEW (OLD wins), Output Quality 4.4 NEW vs 3.8 OLD, Recoverability 4 NEW vs 3 OLD, Cognitive Load tied 3. Run 2 (Mt Erin Rd new job): User Pauses 22 NEW vs 24 OLD, Wall Time 170 OLD vs 165 NEW, Output Quality 4.0 NEW vs 3.0 OLD, Recoverability 4 NEW vs 2 OLD, Cognitive Load 3 NEW vs 4 OLD. With plan-v4 forecast applied: NEW wins **5-0 both runs** (P1 default-go drops pauses to 9 full-tender / 4-6 budget). **Honest reservation flagged in §11**: Hammond reference pack contains NEW-stack outputs from earlier today which biases OLD-stack scores upward → clean-room follow-up needed for definitive call. §10 recommendation: approve plan-v4 → clean-room follow-up → real-bid validation (5-10 bids) → lock primary-stack decision in ~4-6 weeks. Commits `67aacdf` / `20cfe37` / `6c51f97` / `ed66d3f` (sandbox) + `efb261a2` / `49dd109c` (HQ-Vault).

### Blockers
None.

### Insights worth keeping
- Comparison-report bias: when stacks share reference inputs that one stack produced, the receiving stack benefits from the producer's work. Future stack-vs-stack runs need clean-room protocol (no cross-pollination of generated outputs).
- Plan-v4 Hasibul-absorption forecast suggests P1 default-go is the single biggest pause-reducer (6-12 pauses/bid). Building it pays back quickly; runs ahead of P2 trigger phrases on priority.
- Mt Erin Rd is the first stair-install job in LFCS history. NEW stack's lfcs-cost-data-clean would seed a scope-benchmarks/ stair entry on first run, building learning for future stair work. OLD stack has no such mechanism — the system stays as ignorant after Mt Erin Rd as before.
- 2635 Hammond at $416,738 ex GST = 2602 anchor $407,870 + $8,868 (2.2%). Validates 2602 pricing as solid baseline despite 3-year design progression.

### Action items
- [ ] Rocky to review plan-v4 (`_System/plan-v4-hasibul-absorption.md`) — answer 7 open questions in §8, approve or send edits
- [ ] Rocky to review `_System/comparison-report-2026-05-15.md` — confirm or contest 5-axis scoring, decide next-step (clean-room follow-up vs real-bid validation vs hold migration)
- [ ] Rocky to review 6 learning-guide modules and A5 cards — print A5 cards for office wall
- [ ] Bid 2602 fixture migration to HQ-Vault — gated on Rocky approval of plan-v3 + plan-v4
- [ ] Update concept note `TfNSW-bridge-FRP-subcontract-pattern.md` reo productivity range from 22-25 to 20-25 hrs/T (carried from earlier session)

### Resume notes (if picked up later)
All commits pushed to both sandbox + HQ-Vault. Sandbox is `master` branch; HQ-Vault is `main`. Latest sandbox HEAD = the Task 4 status commit. Latest HQ-Vault HEAD = the daily journal update commit (this one).

**Priority next step for Rocky on return:** read `_System/comparison-report-2026-05-15.md` §0 TL;DR + §10 recommendation. Decision required: approve plan-v4 (→ Wave 4 builds 10 patterns) OR hold migration (→ accumulate real-bid evidence first) OR reject (→ patterns deferred indefinitely).

### evening (continued) — claude-code-coo — Wave 4 Hasibul-pattern absorption (Rocky-approved plan-v4.1) + clean-room re-run

Rocky returned mid-session: approved plan-v4 with 3 additions → plan-v4.1. Wave 4 build proceeded per §2 DAG. All 10 Hasibul patterns landed across 5 wave-stages + regression gate + clean-room re-run.

**plan-v4.1 (3 Rocky additions, commit `0ee28c0`):**
- §8 7 open Qs answered (brand `#C80F2E` stays / Wave 3 rename to 11-Handover / NO override for mandatory pauses / client brand precedence / 25 rules verbatim / job-counter as md / confidence-star backfill ⭐⭐⭐)
- New §X NON-NEGOTIABLE PAUSES — 5 pauses hard-locked (`default_mode_locked: true`): Phase 0 grill / sanitisation L1 / sanitisation L2 / SoPA reference-date / dashboard verification handshake
- New §Y CLEAN-ROOM RE-RUN PROTOCOL — re-execute Run 1 without Hammond reference pack to remove the bias flagged in comparison-report-2026-05-15 §11

**Wave 4 build (11 commits across 5 waves + gate + clean-room):**
- W4-Foundation: P5 `_System/STANDING-RULES.md` (26 numbered rules + non-negotiable pause table + precedence order) — commit `0904ab8`
- W4-Standards (3 parallel): P7 `_System/brand-config.md` + `_System/brand_helper.py` (LFCS Red `#C80F2E` per Q1; per-job client-override support) `1c0407c` · P8 `_System/file-routing.md` (37-rule canonical table) + Wave 3 SKILL.md output_path rename to `11 - Handover/` `564a248` · P9 `_System/REFERENCE-PROJECT.md` (2602 canonical worked example, wikilinks only) `3397bd4`
- W4-Catalog: P2 `_System/trigger-phrases.md` (80+ trigger mappings, longest-match resolution) `803be74`
- W4-Skills (3 parallel): P3 `lfcs-rfq-intake/SKILL.md` v1 + `_System/job-number-counter.md` (current_value 2641 next-free) `731c863` · P4 confidence-star schema + 15 baseline records updated + lfcs-feedback-aggregator v2 + lfcs-bid-prep-doc v6 + lfcs-cost-data-clean v2 + Airtable Rates table Confidence Star field added + 23 rows backfilled `⭐⭐⭐ Won-no-recon` `76f61e9` · P10 `lfcs-tender-correspondence/SKILL.md` v1 (INBOUND email capture as .txt per Rule 19) `0c569e4`
- W4-Modify: P1 default_mode + triggers frontmatter across 45 SKILL.md (6 hard-locked: lfcs-pre-grill / lfcs-sanitise-for-external / lfcs-sanitisation-verify / lfcs-payment-claim / lfcs-payment-claim-review / lfcs-dashboard-builder) + folder-spec.md sub-folder additions (11d/11e/11f/05a/05b/05c/09a-d/10a-c) `7675c42` · P6 cowork-session-writeback v2 hard-blocks session-close-if-no-diary + `_System/last-session-marker.json` crash-recovery + STANDING-RULES Rule 20 hardened `b424622`
- W4-Gate: regression audit confirms all 10 frozen 2602 outputs unaffected (Wave 4 patterns either purely additive or contained outside fixture; hard-locks preserve 4 critical pauses required to reproduce fixture outputs) — PASS
- Clean-room re-run: `_System/comparison-report-clean-room-2026-05-15.md` produced `f6d17e0` — Run 1 (2602 re-price) re-executed with both stacks reading ONLY the 2602 frozen file set (NO Hammond reference pack). **Verdict: 5-0 axis split (NEW wins all 5) → PRIMARY STACK CONFIRMED = NEW per plan-v4.1 §Y decision rule.** Key shifts vs raw run: User Pauses Δ1→Δ14 (P1 default-go delivered; NEW 10 pauses vs OLD 24); Wall Time REVERSED (NEW 140 min vs OLD 210; raw had OLD winning 15); Output Quality Δ0.6→Δ1.3 (OLD drops 3.8→3.0 without reference pack; NEW holds 4.4→4.3); Cognitive Load UNLOCKED from tie to NEW Δ1.5. Structural finding: NEW's advantage is INDEPENDENT of reference-pack input. The raw Run 1 near-parity on User Pauses was an artefact of (a) Wave 4 patterns not built and (b) reference pack letting OLD piggyback on NEW outputs.

**Total Wave 4 commits: 13 (11 build + 2 gate/report/status).**

### Blockers
None.

### Insights worth keeping
- Wave 4 P1 default-go flip is the single biggest pause-reducer in practice (Δ14 on User Pauses axis). Forecast in plan-v4.1 §6 was 6-12 — actual delivered 14. Pattern 1 ROI confirmed.
- Hammond reference pack was generating its own bias every comparison run. Clean-room protocol (plan-v4.1 §Y) is the right pattern for any future stack-vs-stack comparison.
- 6 hard-locked pauses is the correct number — Phase 0 grill (Rule 5) + Sanitisation L1 (Rule 6) + Sanitisation L2 (Rule 6) + SoPA reference-date on payment-claim outbound + payment-claim-review inbound (Rules 13 + 15) + dashboard verification handshake (defensive parsing risk). Removing any of these would either (a) break audit trail or (b) leak internal data or (c) create non-compliant SoPA claim.
- Airtable Rates table had 23 rows (not the 18 estimated in plan-v4.1). All got conservative `⭐⭐⭐ Won-no-recon` default per Rocky Q7. Re-running the pricing-history seed in future will promote based on Job Status changes via lfcs-feedback-aggregator v2.
- Mt Erin Rd 2640 is still the first stair-install job for LFCS. Once Rocky returns and the bid runs through NEW stack live, that's real-bid validation #1 for migration unlock.

### Action items
- [ ] Rocky to read `_System/comparison-report-clean-room-2026-05-15.md` §0 + §7 + §10 — confirm clean-room 5-0 verdict
- [ ] Pick first real-bid validation: 2632 Gladesville recommended (RFQ already landed 2026-05-13)
- [ ] After 2-3 real-bid validations clean → unlock HQ-Vault migration
- [ ] Update concept note `TfNSW-bridge-FRP-subcontract-pattern.md` reo productivity range from 22-25 to 20-25 hrs/T (still carried from earlier session)
- [ ] Print A5 reference cards for office wall

### Resume notes (if picked up later)
All Wave 4 commits in sandbox (local-only). HQ-Vault gets this daily journal entry pushed. Sandbox status snapshot at top of `_System/status.md` is the current "where everything is" index. Migration STILL HELD per Rocky autonomous-brief rule "pending 2-3 real-bid validations."

**Priority next step for Rocky on return:** confirm clean-room 5-0 verdict in `_System/comparison-report-clean-room-2026-05-15.md` §7, then identify first real-bid validation target.
