Switch EXE fast-path freshness check from mtime to content-hash (Item 39) - #460
Conversation
… 39) The freshness check was mtime-only over *.py files, so a timestamp-preserving delivery method (a ZIP, xcopy, robocopy) could carry a genuinely changed file whose mtime still predated the built EXE, silently reusing stale logic with no signal to the user -- and requirements.txt/pyproject.toml/runtime.txt changes were invisible to the scan entirely, mtime or not. HP_FAST_CHECK (now with a canonical tools/fast_check.ps1 source) hashes the same *.py file set already scanned, extended to those three dependency files, and compares against a stored ~fast_check.hash.txt via a new :write_fast_hash subroutine called from :success (gated on HP_FASTPATH_USED so the fast-reuse case never pays a redundant second hash pass). Uses [System.Security.Cryptography.SHA256] directly, not Get-FileHash, per this repo's own Utility-module-cmdlet-autoload lesson. Adds tests/selfapps_fastpath_hash.ps1 (uv lane, non-gating for first landing) -- the exact backdated-mtime coverage gap the item asked for -- plus tests/test_fast_check.py unit-testing the isolated script via real pwsh, and a static wiring guard in harness.ps1.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe EXE fast path now uses deterministic SHA-256 hashes over eligible Python and dependency files. Fresh builds persist hashes only after confirmed build success. Tests cover source and dependency changes, missing hashes, payload synchronization, and backdated timestamps. ChangesEXE fast-path freshness
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The new freshness mechanism can still record a source hash for an executable that was not successfully rebuilt, allowing a later run to silently reuse stale application code. This core state-transition issue should be fixed or explicitly accepted before merge; otherwise the change is not yet merge-ready. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

In @.github/workflows/batch-check.yml:
- Around line 638-643: Update the “Upload test logs” configuration to include
both slash- and backslash-style artifact paths for
tests/~selftest_fastpath_hash, covering both run logs, ~setup.log, and
~run.out.txt; also add the corresponding NDJSON row for these newly uploaded
scenario logs.
In `@run_setup.bat`:
- Around line 2189-2192: Replace the HP_FASTPATH_USED-based gate around
:write_fast_hash with an explicit successful fresh-build flag: clear it before
packaging, set it only after the current build creates dist\%ENVNAME%.exe, and
invoke :write_fast_hash only when that flag is set. Add a regression case
covering a stale existing EXE with a skipped or failed rebuild, ensuring the
stored hash is not updated.
In `@tests/harness.ps1`:
- Around line 415-419: Update the assertions near $hasWriteFastHashLabel,
$hasWriteFastHashCall, and $hasWriteModeArg to first extract the :success and
:write_fast_hash subroutine bodies. Match the HP_FASTPATH_USED-gated call only
within :success, and match the payload write invocation only within
:write_fast_hash, while preserving the existing label check and result
reporting.
In `@tests/selfapps_fastpath_hash.ps1`:
- Around line 94-110: After the successful first Invoke-Bootstrap call, assert
that the stored-hash artifact created by the fast-path build exists before
rewriting entry.py; use the existing hash artifact path or helper rather than
introducing a separate location, and ensure the assertion verifies run 1
actually persisted the hash.
- Around line 46-57: Update the non-Windows guard in the
self.fastpath.hash.backdated_mtime test to determine the platform via
[System.Environment]::OSVersion.Platform instead of $IsWindows, while preserving
the existing skip output and early exit for non-Windows hosts.
In `@tools/fast_check.ps1`:
- Line 1: Prepend the TLS 1.2 SecurityProtocol assignment to the PowerShell
script before the existing comment, ensuring it appears before any PowerShell
5.1 Invoke-WebRequest call.

Learning: PowerShell scripts named selfapps_*.ps1 that must remain compatible with Windows PowerShell 5.1 should not rely on the automatic $IsWindows variable, which is unavailable there. Use a compatible operating-system check such as [System.Environment]::OSVersion.Platform instead. CI invokes these scripts with pwsh, where $IsWindows is available, so ensure the chosen check works across both environments.

HP_FASTPATH_USED being unset does not prove a build succeeded this run -- a skipped or genuinely failed rebuild also leaves it unset, and if a stale dist\<env>.exe from an earlier successful run was still sitting there untouched, the original gate would write the CURRENT (changed) sources' hash paired against that OLD binary. The next run would then wrongly trust the stale EXE as "fresh", reintroducing Item 39's own bug one layer down. Fixed with a new, more precise flag, HP_FRESH_BUILD_OK: reset once per fresh build attempt, set ONLY in the 4 genuine build-success branches inside :run_entry_smoke's PyInstaller/Tier-A build block, never on a warn_build_incomplete path. Since a build can only be attempted after the fast path declines to fire, this is a strictly more precise replacement for the old gate, not an additional condition -- :success now checks HP_FRESH_BUILD_OK alone. Also fixes two smaller review findings: harness.ps1's static wiring check now scopes its assertions to :success/:write_fast_hash's own bodies (bounded by the next label) instead of whole-file matches that could pass on unrelated text; the new selfapps test now asserts run 1 genuinely wrote the stored hash before proceeding, closing a gap where a completely broken write side would have been indistinguishable from a working one (a missing hash file also safely forces a rebuild). Uploads the new test's scenario logs as CI artifacts, matching every sibling scenario's convention. Two other CodeRabbit findings investigated and NOT applied, with reasoning left in a PR reply: the $IsWindows Windows-PowerShell-5.1 concern doesn't apply here since this script (like 47 others in the repo) runs via `shell: pwsh` in CI, not classic powershell.exe; the suggested TLS 1.2 SecurityProtocol assignment doesn't apply since fast_check.ps1 makes no network calls at all.

…nd 2 Four fixes from a second CodeRabbit review round on PR #460 (all against commit 8eaa271, the HP_FRESH_BUILD_OK fix): defensively reset HP_FRESH_BUILD_OK at the very top of the file (before the first :try_fast_exe call), not just inside :run_entry_smoke, so a provider-cascade re-entry hitting the preflight-failure early-return can never leave a stale value behind; :write_fast_hash now captures and logs a nonzero hash-write exit code instead of silently swallowing it; selfapps_fastpath_hash.ps1 now validates the persisted hash's actual content (not just existence) and asserts the backdated-mtime precondition the whole scenario depends on genuinely held; and the new ~fast_check.hash.txt artifact is now included in the CI log upload step.

Two real findings, both fixed: 1. ECHO_LINE_RE missed the command-echo-suppressed "@echo" form, so a same-line nested paren pair on an "@echo" line would go untracked the same way the redirected-echo gap did before it was fixed. Now matches an optional leading "@". New regression test test_paren_pair_on_at_echo_line_nested_is_flagged. 2. Real pre-existing bug (not introduced by this PR, but in the diff's review scope): the warnfix-triggered PyInstaller rebuild's two failure branches set HP_BOOTSTRAP_STATE=error but never cleared HP_FRESH_BUILD_OK, so :write_fast_hash would still pair the CURRENT sources with whatever stale, warnfix-incomplete EXE is left in dist\ from before the failed rebuild -- the next run's fast path would then wrongly trust it as fresh and skip retrying the repair. Mirrors the identical PR #460 fix already applied to the ORIGINAL build's own failure branches. Unlike a DLL-bundle/hidden-import repair loop failure (bundling-only, does not need this per docs/agent-interconnect.md), a failed warnfix rebuild means the current EXE genuinely lacks a needed dependency, so the flag must be cleared here too. New static harness check batch.warnfix.fresh_build_ok_clear guards both branches, scoped to :run_entry_smoke's own body so it cannot pass on unrelated text elsewhere. Deliberately did NOT also delete the stored fast-check hash file (as CodeRabbit's own suggested diff did) -- the content-hash comparison already handles the "sources changed" case correctly regardless, and unconditionally deleting it would force an unnecessary rebuild on the next run even when the existing dist\ EXE is still genuinely fine (a transient warnfix-rebuild failure with unchanged sources). Clearing HP_FRESH_BUILD_OK alone is the precise fix. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017SQ1rvJxDbE71pTXJ4QvLV
…-line-paren question (#464) * Close Item 42's tag-classification precondition (lever 1) Classifies the 6 remaining :log tags lever 1's own INFO/BOOT/WARN/ERROR wording never named: STATUS, REPAIR, and HINT are visible-by-default (each is directly actionable or the run's own success/failure readout); INSTALL joins DEBUG/TRACE as suppressed-by-default (it sits strictly beneath the INFO-tier dependency-install progress line already shipped, and the file's own header comment at that call site already anticipated this classification). Also audits every test for a live-console-echo dependency on DEBUG/TRACE/ INSTALL before any tiering mechanism gets built: selfapps_pipgap.ps1 reads ~setup.log (untouched by tiering, not a blocker); selfapps_pvw_overrides.ps1 reads the console-redirected bootstrap log for a [DEBUG] line and would break the moment console suppression ships -- flagged as the one thing that must be fixed in the same change that implements lever 1's actual mechanism. Deliberately scoped to classification + audit only, not the tiering mechanism itself -- :log has 425 call sites, and this repo's own established discipline for a change at that blast radius is one careful slice at a time (see the DLL-bundling and hidden-import repair loops' own multi-slice history elsewhere in this backlog). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017SQ1rvJxDbE71pTXJ4QvLV * Close Item 61: same-line nested paren pairs are unsafe at any depth Real cmd.exe evidence (the paren-nesting hazard probe, PR #461, run manually by the maintainer after this session's GitHub integration hit a 403 trying to dispatch it itself) settles Item 61's last open question: a same-line, self-contained (/) pair nested inside a real if/for block corrupts cmd.exe's parsing at ANY nesting depth, with or without a >> redirection prefix -- even the shallowest case (one level, no redirect) failed identically to the known-broken control. check_delimiters.py's pop() no longer exempts a same-line close from the prose-paren hazard check -- only whether the pair is nested at all matters now, not whether it closes on the same or a later line. A related gap found while verifying against a real regression fixture: the echo-line detector never recognized a redirected form like '>> "%LOG%" echo ...' (the exact shape that broke in PR #445) as an echo line at all, so its own paren pair went untracked regardless of the same-line fix -- closed via a new ECHO_LINE_RE that matches an optional redirection clause before "echo". Two existing tests flipped from asserting "not flagged" to asserting "flagged" (their own comments already said this would happen once the checker caught up); one new test locks in the one shape that remains genuinely safe -- a plain top-level echo/rem with no enclosing block at all. Running the fixed checker against run_setup.bat surfaced 63 genuine, previously-invisible findings -- individually read in context and reworded to remove the literal parens, in batches, following this repo's established one-slice-at-a-time discipline for a change at this blast radius. Every changed line is a rem/echo line; no functional code or log-message content changed except one user-facing echo line reworded for clarity. docs/open-questions.md item 5 removed (fully answered). CLAUDE.md's Item 61 entry closed and moved to docs/agent-closed-backlog.md. docs/agent-lessons-learned.md's corresponding entry updated with the confirmed, final rule.

Updated the check's expected pattern, plus the doc/test references to the old wording that were purely cosmetic (a demo-output sample and a comment/assertion string in a negative-match test that would have passed either way). * Register batch.warnfix.fresh_build_ok_clear in the NDJSON row registry The CodeRabbit-requested HP_FRESH_BUILD_OK fix (commit 986e33f) added a new static harness.ps1 check emitting this row id, but per CLAUDE.md's AGENT DIRECTIVE it was never added to docs/agent-ndjson.md's registry -- caught by the ndjson-registry-check advisory CI job. python tools/ check_ndjson_registry.py now reports a clean PASS (328/328 IDs matched). * Fix false positive: nested prose paren at top level wrongly flagged CodeRabbit's review of PR #464 found a real bug in check_delimiters.py's Item 61 fix: the "already nested" hazard test was bool(self.stack), true the moment ANY bracket is open -- including a prior prose paren from the SAME echo/rem line's own text, not just a genuine enclosing if/for block. Reproduced directly: `echo outer (inner (detail))` at true top level (no enclosing block anywhere) wrongly flagged its own second paren. Fixed by adding a per-line `is_prose` fact to StackItem (independent of stack state) and basing the hazard verdict on whether a genuine structural (non-prose) bracket is already open, not on stack non-emptiness. Verified against the reported false positive (now clean) and both existing true-positive shapes (same-line and cross-line pairs genuinely nested inside a real if(...) block -- still correctly flagged). No live instance of this shape existed in run_setup.bat itself (clean before and after), so this closes a latent risk for future edits. --------- Co-authored-by: Claude <noreply@anthropic.com>
Item 39 (EXE fast-path freshness check, mtime-only -> content-hash) was fully implemented, CodeRabbit-reviewed, and tested as of PR #460 (2026-08-23) -- confirmed by re-reading its own text, which contains no remaining "still open" work, unlike Items 38/42 which explicitly do. It was left in CLAUDE.md's Active Backlog past its actual completion date, past this file's own "1000+ tokens per session" cost for an item with nothing left to implement. Moved verbatim to docs/agent-closed-backlog.md per this repo's house rule, updated the two auto-loaded cross-references in docs/agent-interconnect.md and docs/agent-ndjson.md to the established "former Active Backlog Item N (closed)" wording. In-code rem comments in run_setup.bat/tools/tests keep their stable "Item 39" historical pointers unchanged, matching existing precedent for other closed items (e.g. Item 45's own comments). Pure documentation reorganization -- no functional or test change.
Pre-existing inaccuracy caught by CodeRabbit's review of the Item 39 archival: this description of :write_fast_hash's gate still said "gated on HP_FASTPATH_USED being unset" -- but per Item 39's own (newly-archived) closed-backlog text, HP_FASTPATH_USED was replaced by the more precise HP_FRESH_BUILD_OK flag before that PR (#460) landed. Confirmed against the real run_setup.bat source: the actual call site is "if defined HP_FRESH_BUILD_OK call :write_fast_hash". Fixed the wording to match shipped behavior.

Summary
CLAUDE.md's Active Backlog Item 39: the EXE fast path's freshness check (
HP_FAST_CHECK) was mtime-only over*.pyfiles, exposing two gaps:(a) A timestamp-preserving delivery method (a ZIP,
xcopy,robocopy) could carry a genuinely changed file whose mtime still predates the built EXE, silently reusing stale logic with no signal to the user (the item's own "colleague emails a fixedanalysis.pyinside a ZIP" scenario).(b)
requirements.txt/pyproject.toml/runtime.txtchanges were invisible to the scan entirely, mtime or not.HP_FAST_CHECKnow compares a content hash, not mtime -- a composite SHA256 over the same non-infra*.pyfile set already scanned, extended to those three dependency files when present. This closes both exposures at once rather than picking one of the item's two suggested fix directions.Gave this payload a canonical source,
tools/fast_check.ps1(it previously had none -- only an inline base64 blob). Two modes via a second positional arg:check(default, unchanged:try_fast_execall site) compares against a stored~fast_check.hash.txt;write(new subroutine:write_fast_hash, called from:success) (re)writes it after a genuine fresh build attempt -- gated onHP_FASTPATH_USEDso the already-fast reuse case never pays a redundant second hash pass.Uses
[System.Security.Cryptography.SHA256]directly, notGet-FileHash, per this repo's own "Prefer raw .NET types over Utility-module cmdlets" lesson (docs/agent-lessons-learned.md) --Get-FileHashis not guaranteed to auto-load in the-Fileinvocation shape this repo's embedded helpers run under on real Windows PowerShell 5.1.A missing stored hash (first run under this fix, or an EXE built by an older
run_setup.bat) is a safe "not fresh" default -- forces exactly one rebuild, never a false "fresh."Coverage
tests/selfapps_fastpath_hash.ps1(uv lane, non-gating for first landing) is the exact scenario Item 39 itself asked for: run 1 builds the EXE printing a V1 token;entry.pyis rewritten to print V2 and its mtime backdated to 2001-09-09 (well before the EXE's own mtime) before run 2; asserts run 2's captured EXE stdout shows V2 (not V1) and the "Fast path: reusing" line is absent -- direct evidence a genuine rebuild happened, not just a log-text coincidence.tests/test_fast_check.pyunit-tests the isolated script directly via realpwsh(6 scenarios: no stored hash, write-then-fresh, backdated-mtime content change, dependency-file-only change, rewrite-after-change, missing EXE), plus aPayloadSyncbyte-equality check againsttools/fast_check.ps1.tests/harness.ps1's newbatch.fastpath.hash_writestatically guards the:write_fast_hashwiring.docs/agent-ndjson.md's row registry,docs/agent-interconnect.md's "EXE fast path" section (the read/write call-site pairing that must stay in sync).Non-gating for its first landing (uv lane) since this touches the highest-traffic path in the whole file (every run reaches
:try_fast_exe) and could not be verified end-to-end on real Windows locally -- promote once proven stable across several real CI runs, matching this repo's established graduation pattern.Verification
