docs(field-log): revised prose for the revitalization log

[mparrett]

Draft, so there's something concrete to react to rather than a rendered link. Part of #4 (row 5) — merge, comment, or close.

What this is

I kept revising this log after you'd merged it, so the two copies drifted. This brings the revised prose over top of your corrections, ending the divergence.

The rewrite is about stance. I wrote the original before I understood the process layer, and it shows: "the repo we inherited", "the agent's machinery", "the harness is provenance, not garbage". That reads like I'd found something abandoned. What was actually there was a solo project with a working process layer I hadn't looked at yet.

A few examples:

• §1 What the machine left behind → What a fresh clone met
• "the agent ran its own checks, on its own machine" → "the loop ran its checks locally, which is what a solo project does right up until someone else needs to run them"
• "the artifact is strong where humans are weak" → "almost nothing we fixed was a quality problem, it was the absence of an independent seat"

Your corrections

Both from #1 (merged as 137d449) are preserved verbatim, including the ITER-0005 caveat. Wanted to be careful not to silently revert your edits — verified.

Two additions: a §7 note that quotes the previously incorrect "never had a reviewer" claim, and a paragraph crediting you for the corrections.

Notes

• Assumes this page lives here, which is tentative and depends on Where's the canonical home for the FMPL HTML/docs artifacts? #4. Source and internal links (fmpl-tour.html, fmpl-field-log.html) point at this repo; nothing references my fork.
• Rendered, if easier than reading the diff: https://mparrett.github.io/fmpl/fmpl-rehab-log.html — same prose, differing only in source links and one extra sentence linking a process-notes page that isn't proposed here.
• Overlaps docs(pages): point every source link at nnunley/fmpl [DRAFT] #2, which touches this file's masthead and footer. If this lands, I'll rebase that.
• Retitled "Opening the Door". Let me know if you prefer to keep the previous title — I lean toward the new one, but happy to change it.
