Summary

  • Closes CLAUDE.md Active Backlog Item 30: a second dedicated compression pass on the two
    auto-loaded-every-session knowledge docs (docs/agent-interconnect.md,
    docs/agent-lessons-learned.md), both already compressed once before.
  • Read both files in full, then tightened verbose/transitional phrasing and collapsed restated
    setup context throughout, without cutting any fact, code snippet, name, number, or citation.
  • Measured before/after via wc -l -w:
    • docs/agent-lessons-learned.md: 1369 → 1343 lines, 14261 → 13804 words (~3.2% word
      reduction). Had more compressible narrative across multi-entry debugging "sagas" (the
      async-output-capture rewrite history, the DLL-bundling %-sanitizer saga, the
      exe_hint_rerun.ps1 unbounded-wait investigation).
    • docs/agent-interconnect.md: 1984 → 1981 lines, 21039 → 20991 words (~0.2% word reduction).
      This file is a denser, one-fact-per-sentence incident/postmortem log that had already
      absorbed most of the easily-removable narrative in the prior compression pass, so this round
      found much less to safely cut.
  • Added a note in the closed-backlog entry: if this file needs to shrink further later, the next
    lever is structural (e.g. collapsing the DLL-bundling repair loop's numbered-bug narrative into
    a table, or splitting the file by feature area) rather than further sentence-level trimming —
    not attempted here since it needs its own dedicated cross-reference verification pass.
  • Moved Item 30 from CLAUDE.md's Active Backlog to docs/agent-closed-backlog.md's Closed Active
    Backlog Items section (keeping its original number), and updated CLAUDE.md's Active Backlog to
    the explicit "Nothing here." empty-list marker per that section's own convention.

Test plan

  • tools/run_sanity_sweep.sh docs/agent-interconnect.md docs/agent-lessons-learned.md docs/agent-closed-backlog.md — all checks pass (compileall, pyflakes, delimiters, yamllint, actionlint, ASCII sweep, PowerShell AST parse sweep, pytest 515 passed / 3 skipped).
  • Prose-only diff confirmed via git diff --stat — no code/test files touched, so CI is expected to stay green quickly.

…essons-learned.md

Read both auto-loaded knowledge docs in full and tightened verbose/restated
phrasing throughout without cutting any fact, code snippet, name, number, or
citation. agent-lessons-learned.md (1369->1343 lines, 14261->13804 words) had
more compressible narrative across its multi-entry debugging "sagas";
agent-interconnect.md (1984->1981 lines, 21039->20991 words) is a denser
one-fact-per-sentence incident log that had already absorbed most of the
easy compression in the prior pass, so this round found much less to cut
safely. Closed as CLAUDE.md Active Backlog Item 30, moved to
docs/agent-closed-backlog.md with before/after metrics and a note on what a
future structural (not word-level) pass would need to do next.

In `@docs/agent-interconnect.md`:
- Around line 775-777: Update the “Two-stage PowerShell/Python split”
description to state that the Python stage depends on the freshly extracted
embedded interpreter, rather than claiming no Python interpreter exists
anywhere. Preserve the explanation that the embed tier is selected before venv
and system providers.
- Around line 739-742: Update the provider-consumer coverage statement in the
documentation to say that most HP_ENV_MODE/HP_ENV_READY consumers are
tier-agnostic, while explicitly identifying :after_env_mode_selection as a
required integration point because of its embed branch. Preserve the historical
tier-label explanation and exact-string/boolean behavior.

In `@docs/agent-lessons-learned.md`:
- Around line 531-539: Update the accepted-risk entry for %HP_ENTRY% to
explicitly include percent-sign-driven expansion and caret parsing risks at the
three call :log sites, alongside the existing metacharacter risks. Preserve the
current call-site list and accepted-risk status, and note the potential
environment-value leak from the second call expansion pass.
- Around line 1230-1238: Revise the exit-code contract documentation to state
that exit code 2 is a malformed-header signal only after UTF-8 validation and
package-directive filtering, and only for the tested uv versions and command.
Update the surrounding claims in the malformed-header repair guidance without
treating all exit-2 cases as malformed TOML, and preserve regression coverage
for malformed, trailing-whitespace, and non-UTF-8 inputs.

Learning: In the documentation files describing the removed UNC warning check in `run_setup.bat`, state only verified behavior: the check emitted `[WARN] UNC paths not supported` for an ordinary local path and was removed because the separate UNC-prefix guard already handles UNC detection. Do not assert the exact `findstr` or cmd.exe backslash-parsing mechanism, since it was not independently verified.

- agent-interconnect.md: the embed tier's "runs when NO Python interpreter
  exists anywhere" claim was imprecise -- embed is deliberately tried before
  venv/system, so an ambient interpreter could exist; this tier just never
  probes for one. Clarified to describe what's actually true (no interpreter
  secured BY THE BOOTSTRAPPER yet, not none-on-the-machine).
- agent-interconnect.md: disambiguated the provider-chain reorder's "no
  downstream consumer needed to change" claim, which is scoped to the
  reorder itself, not embed's original introduction (which did add a
  consumer change at :after_env_mode_selection, documented two paragraphs
  later) -- a reader could otherwise read this as self-contradictory.
- agent-lessons-learned.md: the %HP_ENTRY% accepted-risk entry only listed
  the <>&| redirection hazard; 3 of its 4 call sites are genuine `call :log`
  invocations also exposed to the call-triggered second-expansion-pass %/^
  hazard documented later in the same file. The 4th site is a plain `echo`
  (not `call`), so it's unaffected -- noted the distinction precisely.
- agent-lessons-learned.md: the "exit code 2 exclusively means malformed
  header TOML" claim was too strong -- confirmed directly in
  tools/pep723_writeback.py's own source that uv add --script's clap parser
  also exits 2 for non-UTF-8 input and pip-style package directives, which
  is exactly why that tool pre-filters both before ever calling uv. Exit 2
  is only a reliable malformed-header signal within a caller's own guarded
  context, not as a general fact about uv's own exit code.
