docs(governance): PENDING-101 blocker resolved — Read reaches Desktop, bash does not

The steward supplied the path; the Read tool opens it (1023.8KB, ~36pp). The bash
sandbox still cannot, so the instrument matters and is now named in the item.

Records the generalisable lesson: 'I cannot read X' was true of one instrument
and false of another, and I twice reported the instrument's limit as a fact about
the world (aliased ls -> count 0; find -> silent empty) before controlling it.
The brief already demands a positive control before any absence claim about a
gate; the same rule was needed one layer down, on my own file search.

Also records a small real contamination: pages 1-3 were read tonight to test
reachability, so tomorrow's Phase 1 baseline is knowingly formed with the
executive summary already seen. Named rather than pretended away — the brief
orders Phase 1 before Phase 1.5 precisely to keep that baseline clean.

 ## Active Session
 > ⛔ **NEXT SESSION = PENDING-101, the jurist's cross-repo research brief on UK AISI incident INC-2026-07-28-01.** Read the item in full before anything else; it carries the brief verbatim (Phases 1 / 1.5 / 2 / 3, hard boundaries, the four questions). **Read-only pass — no commits, no edits, no fixes.** All chamber/engine work below — the retrieval measurement, the 5 skill-harvest proposals, **REVIEWED-87's placement** — is **deferred to the following morning** by steward instruction.
-> ⛔ **BLOCKER, unresolved at dispatch:** Phase 1.5's primary source is at `~/Desktop/…INC-2026-07-28-01.pdf` and the executor **cannot read `~/Desktop` or `~/Downloads` at all** — TCC `EPERM` on the *directory*, so presence is **undetermined, not absent** (positive control: `~/_Dev`, `~/dotfiles`, `~/.claude`, `~/Documents` all read fine). Ask the steward to copy it to `~/Documents/` or paste the text. **Phase 1 is unblocked and runs first regardless.**
+> ✅ **BLOCKER RESOLVED:** the **`Read` tool reaches `~/Desktop`; bash does not** — use `Read(..., pages=...)` on the PDF (~36 pp). ⚠ Pages 1–3 were already read tonight to test reachability, so the Phase 1 baseline is *knowingly* formed with the executive summary seen — a bounded, recorded exposure, not a clean slate. ⚠ Superseded note follows: Phase 1.5's primary source is at `~/Desktop/…INC-2026-07-28-01.pdf` and the executor **cannot read `~/Desktop` or `~/Downloads` at all** — TCC `EPERM` on the *directory*, so presence is **undetermined, not absent** (positive control: `~/_Dev`, `~/dotfiles`, `~/.claude`, `~/Documents` all read fine). Ask the steward to copy it to `~/Documents/` or paste the text. **Phase 1 is unblocked and runs first regardless.**
 > ⚠ Cutoff is May 2026, incident is 2026-07-28/08-04: **the report is outside training — read the primary source, never recall it.** Mark sourced vs inferred. And do not pre-fit findings to threads we already like.
 
 - [Session 2026-08-05 — the quoted tier accepts three of seventeen](session-2026-08-05-the-quoted-tier-accepts-three-of-seventeen.md) — **The engine's quoted tier measured against real human citation for the first time: 3/17 accepted, and the largest single cause is a FULL STOP, not markup** (+5 vs +3). `verify_quote`'s first production call — it located the known mislocation unprompted (`found-elsewhere: 1181`). **Four of my claims died today**: the markup framing; a census flag I raised→withdrew→had to UN-withdraw (the withdrawal *inferred a breakdown from a total*); a forward-window locator that reported a spurious uniform offset **twice** (Δ−30, Δ−25 — truth is Δ−1); and Q1's rationale, overturned by the jurist. **`fidelity_equivalence@3` RATIFIED + BUILT** (REVIEWED-87 drafted, **not yet placed**) — pre-registered 3/17→6/17, then measured exactly that; suites 22/22 · 43/43 · 24/24. **The conversion runbook has NEVER parsed** (8/8 commits; fixed `4f8ad64`). **PENDING-86 (a)+(d) built** — jurist given `chamber-spec` + `governance_search`; **the ruling changed materially the moment it could read primary text**, and its structural pass found REVIEWED-11/-12/-74 hidden from `item_spans` by indentation (steward unindented; 78→81 items). **The finding that cuts inward: the decisive §II.3 sentence was in my own read output and I did not surface it** — containment verifies that what you quoted is ACCURATE, never that you quoted what MATTERS; limit now written on the instrument. P5 executed (Δ−1 uniform, sha-bound, composite split applied); PENDING-99/100 filed. ⚠ Said *'Symmetria active'* at wake and never invoked it — decorative line, no ledger today. **PULLING THREAD unchanged and one day older: ask the corpus real questions.** Second consecutive day on scaffolding — every step steward-directed, so not drift as a choice, but drift as a result.
