Goal

Correct the three planning documents before Session 2 builds content/ from them. Three rounds of amendments, all approved by Paige: the resume-PDF and Vercel facts (2026-09-10); the source review that checked every seed fact in DESIGN §3.2 against the staged sources and LinkedIn (2026-09-11); and a review of the specs’ own instructions, which found three Session 4 tasks that could not be carried out against the sources that actually exist (2026-09-12).

What shipped

Round 1 (commit 477d150, approved 2026-09-10):

  • DESIGN §3.4 / §5.4: the claim that the resume contains a phone number was false; the Paige-Rattenberry-Resume-web.pdf export it depended on never existed. Session 6 now ships the hand-made PDF directly, and the resume test gains a "no unfilled [ADD placeholder" rule.
  • IMPLEMENTATION_PLAN S0-B and Session 6, and SESSION_PROMPTS, updated to match.
  • IMPLEMENTATION_PLAN S0-E and §6 rewritten to describe the Vercel setup as built: production branch launch, "Only build pre-production", Vercel Authentication on, so no production deployment exists until Session 8 — plus docs/build-log/s0e-vercel.md and a README note.

Round 2 (this commit, approved 2026-09-11):

  • DESIGN §2: the capstone deep page now describes the system as built and marks the ML curve-progression model as the envisioned next phase; the thesis deep page says ground truth was induced by watermarking chest X-rays, not taken from expert annotations.
  • DESIGN §3.2: seed facts corrected — valedictorian timestamp 45:27, MLADS co-area chair, Aspire Jul 2023 – Feb 2025, the podcast named with its real dates, ICAMES venue, Clinical CoPilot's Executive Challenge honourable mention, Samsung explicitly in scope, the 2018 FAISAL research, and the top 5% and the honourable mention sourced to LinkedIn.
  • DESIGN §3.3: source: linkedin now points at the LinkedIn profile, snapshot of 2026-09-11 (or the source inventory's verbatim quotes for the sections LinkedIn's PDF export omits). DESIGN §1 says 220+ PRs.
  • DESIGN §5.4: names the current resume of record rather than a dated filename that keeps moving.
  • IMPLEMENTATION_PLAN §2: the Read tool's pages parameter needs pdftoppm, which is not installed; whole-file reads work (verified on the 49-page thesis).
  • IMPLEMENTATION_PLAN Sessions 2 and 4, SESSION_PROMPTS Sessions 2 and 4: read the LinkedIn snapshot, INVENTORY's settled facts win any conflict, and the corrected capstone/thesis framing.

Follow-up, same day, after Paige answered the last open questions:

  • Stryker runs Sept 2021 – May 2022 (DESIGN §3.2 and the resume of record; the Apr 2022 end date came from the older resume). The Azure bullet's "cut storage access latency" wording is approved.
  • Session 7 also bumps actions/checkout and actions/setup-node to v5. v4 targets Node 20, which GitHub deprecated, so every CI run logs a deprecation annotation; Session 7 is already editing ci.yml to add the Lighthouse job, so it is the cheapest place to fix it.

Round 3 (approved 2026-09-12) — a pre-Session-2 review of the specs themselves, rather than of the facts in them. Round 2 made every fact true; round 3 makes every instruction achievable:

  • Session 4 could not have passed its own acceptance. IMPLEMENTATION_PLAN and SESSION_PROMPTS still told it to prefer figure exports in the private source folder, to fall back to "render that page in Chromium via Playwright and crop", and to place 3–5 figures per deep page. INVENTORY.md says otherwise: no figure exports are coming, and a missing figure should be drawn or described rather than cropped out of a PDF. For the capstone it is also barred twice over — the decks are not cleared for posting and the SFU article's photographs are SFU's copyright, link-only. Session 4 now recreates the thesis's own figures 3.1–4.7 (Paige's experiment output), draws original diagrams for the capstone pipeline, and carries the rest in prose. S0-A's figure-export request is marked closed so no later session goes looking for it.
  • Shipping the thesis PDF whole would have published a page the inventory excludes. Session 4 said "link to thesis PDF if cleared (public/docs/)"; INVENTORY.md clears the thesis except p2, a scanned page with no extractable text. The shipped copy must now have p2 removed with pdf-lib (already a Session 6 dependency — this machine has no qpdf or pdftk), recorded as such in assets.json.
  • The valedictorian video URL was nowhere in INVENTORY.md, but Session 4 gates the click-to-load embed on finding it there, so the embed would have been silently skipped. Recovered from a link annotation inside the speech PDF and written into INVENTORY.md: https://www.youtube.com/watch?v=RKIO5EvDJ5Y&t=2727s. t=2727s is exactly 45:27, which independently confirms round 2's timestamp correction.
  • pdftotext is installed at /mingw64/bin/pdftotext (it ships with Git Bash). §2 recorded only that pdftoppm is missing, which left whole-file reads as the apparent only option. pdftotext -layout -f N -l N gives page-accurate text, which is what Sessions 4 and 5 need to confirm a claim's page in its source document. Image-only pages and the capstone proposal's subset font still need the Read tool.
  • The phone gate is now specified as text-only. The DESIGN §3.4 pattern was tested against every date and metric the resume carries (Sept 2021 - May 2022, 16th/1,253, IEC 62304, 45:27, GPA 3.89, 220+): zero false positives, and it does catch a space-separated nine-digit ID shape (NNN NNN NNN) that a naive regex would miss. But it matches SVG path data, and over a binary it depends on the bytes — and Session 2's acceptance scans public/, which will hold a JPEG. The examples here are written with N placeholders so these public documents do not themselves trip the gate.
  • The headshot now has a verified command. INVENTORY.md required baking the rotation in before stripping EXIF/XMP but named no tool, and neither ImageMagick nor exiftool is installed. sharp is already in node_modules; .rotate() applies EXIF Orientation = 6 to the pixels and sharp writes no metadata, verified to give 433×577 with exif/xmp/icc all absent. ffmpeg is the trap: it applies EXIF orientation while decoding, so the intuitive -vf transpose=1 rotates a second time and lands back on its side.
  • content/research.ts had a guess waiting for it. The resume gives the combined range "Aug 2020 – Apr 2021" for Rostrum Medical and HealthTech Connex, while LinkedIn dates them separately (HealthTech Connex Aug 2020 – Apr 2021, Rostrum Medical Apr 2021). Settled in INVENTORY.md as one item with the resume's combined range.
  • DESIGN §3.2's EEGTMS app line read as though there were a link to give; StimMap3D is the only project repository the site links. Reworded to say so.

Decisions and why

  • The source inventory (INVENTORY.md) is the tie-breaker, ahead of DESIGN §3.2 and the resume. The seed content in DESIGN was extracted once on 2026-09-07 and has already drifted twice; INVENTORY is the file Paige and each session actually maintain.

  • The capstone's ML model is described as proposed, never built. Paige confirmed the team envisioned training it on the pressure data they collected; both decks list it under future work and the SFU article does not mention ML at all.

  • The thesis method is stated as the thesis states it: ground truth induced by watermarking (not expert annotations), so the explanation methods could be scored at all.

  • The resume was revised in the same pass (Resume, revised 2026-09-11), so content/ and the shipped PDF will agree from the start. The private source folder stays untracked; nothing from it is committed.

  • A spec that cannot be satisfied is worse than a spec that is merely wrong, because the session discovers it halfway through and improvises. Round 2 checked the facts in the documents; round 3 checked whether the instructions could still be carried out against the sources that actually exist. Both Session 4 defects came from the same place: the specs were written when Paige was still expected to supply figure exports, and were never revisited after INVENTORY.md closed the inventory.

  • Verify tooling by running it, not by reading the last note about it. §2 said pdftoppm is missing, which was true and had quietly been generalised into "PDF page extraction is unavailable". pdftotext was there the whole time, and the headshot instruction named a step with no installed tool to perform it. Both were settled in this session by running the commands and recording what actually came back.

Skills / tools used

Read (PDFs: resume, thesis, capstone decks, SFU article, LinkedIn export), WebFetch (public LinkedIn profile — the logged-out view hides Experience, which is why Paige exported the Save-to-PDF snapshot), pdfjs-dist in the scratchpad for text extraction, Word COM for the resume PDF export, git/gh.

Round 3 added: pdftotext (per-page text, and the discovery that it is installed at all), sharp and ffmpeg/ffprobe for the headshot rotation and metadata test, grep over the raw PDF for the valedictorian link annotation, the DESIGN §3.4 regex run against both real resume strings and a binary JPEG, npm run lint/typecheck/test to confirm the tree Session 2 starts from, and gh pr checks/git log main..HEAD to catch the stale PR body.

What Claude got wrong and how it was caught

  • The 2026-09-09 resume revision introduced two claims the sources do not support — "expert-annotated ground truth" on the thesis and an ML prediction system on the capstone — by paraphrasing the older resume instead of checking the thesis abstract and the capstone decks. Caught in this session's review by reading both sources end to end; the two claims had been in the repo's specs for four days.

  • The same revision put Aspire at Nov 2022; LinkedIn says Jul 2023, and Paige confirmed Jul 2023.

  • Round 2's first draft of the resume ran to three pages. Caught by exporting the PDF and counting, not by assuming; the fix was tightening wording, not dropping facts.

  • Rounds 1 and 2 reviewed the specs' facts and declared them ready for Session 2, without checking whether the specs' instructions still matched the sources. Two Session 4 tasks were unsatisfiable as written (figures that do not exist, a fallback the inventory forbids) and a third would have published a page the inventory excludes. Caught in round 3 by reading Session 4 against INVENTORY.md line by line instead of trusting round 2's sign-off.

  • The PR #2 body still listed the Stryker dates and the Azure wording as "Still open" after commit b1bcb2f had closed both, and never mentioned that commit's third change. Caught by diffing the body against git log main..HEAD rather than against memory of what the PR was for.
