## Acceptance Contract
Acceptance level: attested
Completion is not accepted from prose alone. End with a structured acceptance report.

Criteria:
- criterion-1: Return a concise result and residual risks when applicable

Required evidence: manual-notes, residual-risks

Finish with a fenced JSON block tagged `acceptance-report` in this shape:
Use empty arrays when no items apply; array fields contain strings unless object entries are shown.
`criteriaSatisfied[].status` must be exactly one of: satisfied, not-satisfied, not-applicable.
`commandsRun[].result` must be exactly one of: passed, failed, not-run.
`manualNotes` and `notes` are optional strings; an empty string means no note and does not satisfy `manual-notes` evidence.

type: thinking

thinking: We need act as child subagent. The task: "can you check this html for errors". We need check the HTML for errors. We have files in project context AGENTS.md. Need read index.html and maybe CSS/JS. The user likely wants an HTML validation. Need inspect index.html. Need run validation? Use bash tools maybe HTML tidy? Need check structure. Need maybe no edits. Acceptance contract attested, require manual-notes, residual-risks, structured JSON. We need return concise result plus acceptance-report block. We need read relevant files first. Let's list directory, read index.html, maybe CSS/JS to cross-check. We can also run an HTML validator via CLI? tidy? If not installed, maybe install? Could use Python html.parser or vnu? Could run `tidy -e index.html` if tidy exists. Need check. Also `xmllint`? HTML5 not XML. Could use `python -m html.parser` with script to catch unclosed tags. But better use `npx html-validate` maybe no Node? The project has no dependencies but we can run any tool. We need avoid installing if not needed; but to validate, maybe `tidy` is present. Let's check. Also maybe use `curl` to W3C validator? Internet maybe not. We can use bash. First read index.html.

A space to come home to yourself

Where men gather to grow together

        In a world that asks men to carry everything in silence, we offer something rare:
        a circle of brothers who see you, hear you, and walk beside you.
        No masks. No performance. Just real men doing real work.

            The Circle

Why we gather

          For too long, men have been taught that strength means isolation. We believe the opposite:
          true strength is found in vulnerability, in community, and in the courage to show up fully.

Authentic Connection

Drop the armor. In circle, there is no hierarchy, no fixing, no advice-giving. Just men holding space for one another. Sharing truth. Witnessing without judgment.

Nature as Teacher

Our circles and retreats are held in nature. The forest, the mountains, the rivers — they remind us of something ancient in ourselves. Something wild and whole.

Inner Work

We use proven somatic and meditational techniques to help you drop from the mind into the body. To feel what has been unfelt. To heal what has been unhealed.

          Our Practices

The tools we work with

          Each practice is chosen for its ability to take you deeper — beyond words, beyond story, into the body and the present moment.

              <path d="M12 16v-4M12 8h.01"/>
            </svg>

Meditation

Guided and silent practices to quiet the mind, open the heart, and meet yourself as you are. From mindfulness to deep trance states.

Music & Sound

Live instruments, sound journeys, and chanting. Music is medicine. It bypasses the intellect and speaks directly to the soul.

              <polyline points="14 2 14 8 20 8"/>
            </svg>

Power of Touch

Conscious, consensual touch practices. Holding, pressing, receiving. In a world starved of healthy masculine touch, we reclaim it as healing.

            </svg>

Breathwork

Transformational breathwork sessions to release stored emotion, energize the body, and access altered states of consciousness.

thinking: Need check HTML for errors. Let's inspect CSS/JS? Not necessary but could cross-check anchor IDs present. For HTML validation: run `tidy -e index.html` or use vnu. Check if tidy installed. Also maybe `python -m html.parser`? Let's run tidy and maybe `html-validate` via npx. First check tools.

thinking: tidy not installed, html-validate not installed. We have node. We can install html-validate? It's a CLI via npm. But project is static, no deps. We can npx install? `npx html-validate index.html` will download. We can try. But no network? The environment may have internet. We can also use python with html5lib or standard library. There is a Python html.parser that doesn't validate but can parse; could catch mismatched tags with a script. Better to run `npx html-validate` for real validation. Also maybe use `python3 -c` with html.parser to detect mismatched tags/unclosed. We should check. Need be careful: HTML5 is forgiving. `html5lib` may not be installed. Node `html-validate` can validate. Let's try npx. But if network fails, fallback Python. Also check w3c? Could use `curl` to validator, but no direct? web_explore? Not needed; local validation. Use bash.

thinking: html-validate produced errors. Need assess which are actual errors vs style rule (void-style: expecting omitted end tag for self-closing void elements). In HTML5, `<meta />`, `<link />`, `<img />` are valid either as void tags with self-closing slash or without. The `html-validate` default "omit" style requires no slash; not an error. Should mention as convention, not real HTML errors. But rule is project default? No HTML validation rule. W3C validator likely accepts self-closing void tags. We can verify via W3C? Possibly network. Use `curl`? Direct web maybe. Or use `python html.parser` parse. Need provide concise result and residual risks. The task: "can you check this html for errors". They likely want syntax issues. Use a parser that is strict maybe. Let's also run W3C validator via web_explore? Maybe not necessary but nice. Could use web_explore search? Actually W3C has API. But we don't have direct HTTP tool except curl. The instructions say for web research use web_explore, but for validation we can use local. We can also run `python3 -m html.parser`? It doesn't report errors. We can write a small script using `html.parser` to detect unclosed tags and raw ampersands? But raw & in text content is not syntax error but should be encoded. We need decide. Let's also run W3C by curl with output? It may require network. Let's try `curl -s 'https://validator.w3.org/nu/?out=json'` with uploaded file. If it fails, fallback. Use bash.

command: cd /mnt/flash1/code/webpage && curl -s -F out=json -F "file=@index.html" "https://validator.w3.org/nu/" | python3 -m json.tool | head -n 120 || true


text: Use context-mode MCP tools (execute, fetch_and_index) instead of inline HTTP clients. Raw curl/wget output floods the context window. For an MCP-down escape hatch, use silent + file output: `curl -s -o /tmp/x.json URL` or `wget -q -O /tmp/x.json URL`.


thinking: The environment disallows raw curl output. It says use MCP tools or silent + file output. We can do `curl -s -o /tmp/w3c.json ...`. Let's do that.

command: cd /mnt/flash1/code/webpage && curl -s -o /tmp/w3c.json -F out=json -F "file=@index.html" "https://validator.w3.org/nu/" && python3 -m json.tool /tmp/w3c.json | head -n 150 || echo "W3C validator request failed"

thinking:
W3C validator returns only info-level trailing slash on void elements, no errors. Good. html-validate flagged style and a11y issues, not parse errors. Need examine raw & issues: line 6 meta description contains "Men's circles for deep connection, emotional growth, and brotherhood. Group sessions and retreats with meditation, breathwork, music, and the power of touch." No raw & in attribute? Wait line 6 has no ampersand. But html-validate said line 6:47 raw "&" must be encoded? Let's locate line numbers. In original, line 6 is meta description? Actually line numbers: 1 DOCTYPE, 2 html, 3 head, 4 meta charset, 5 viewport, 6 title, 7 description. html-validate line 6 raw & at column 47. But line 6 is title: `<title>Grounded Brotherhood - Men's Circles & Retreats</title>` contains ampersand. Indeed raw ampersand in text content; should be `&`. W3C validator did not flag? It didn't because text content of title perhaps not flagged? Actually raw & in HTML is parse error unless part of entity? In HTML, unescaped ampersand is allowed in text if not followed by named reference? The HTML spec says ambiguous ampersand error? W3C validator might not flag because parser allows? html-validate flags. Better to encode `&` as `&`. Also line 143 and 179 raw & likely in text: `the rivers —` maybe `—` starts with &, html-validate sees raw "&"? Wait `—` is entity, no issue. But line 143: Let's count. Could be `the rivers —` with entity includes ampersand. Maybe html-validate sees `&` followed by `mdash;`? That should be fine. Hmm line 143: probably text "Drop-In Welcome"? Let's check. Need identify exact raw ampersands. W3C didn't flag raw &, meaning it's probably fine in HTML5 (unless followed by semicolon? Actually `&` followed by space is not parse error; html-validate is stricter). The title `&` should be `&` ideally. Also description meta maybe none. The html-validate lines: 6 (title), 143, 179. Let's inspect those lines. Also line 28 button missing type. Landmarks unique nav? It has two nav elements: top nav and footer nav; both no aria-label. Accessibility recommendation, not HTML syntax error. The button missing type default is submit; since not in form, type="button" recommended. But not HTML error. Should we fix? The task is to check for errors, not necessarily fix. Acceptance contract says completion not accepted from prose alone, but for an audit maybe no code changes. But we can optionally fix? The task "check this html for errors"—as subagent maybe report findings. However the acceptance contract expects changedFiles, tests etc. If we make no changes, changedFiles empty. That's okay for audit. But we should decide whether to fix the actual issues. The user asked "can you check this html for errors". They may expect we find errors and maybe fix them. As an implementation subagent? But this is a review/audit task. The contract says attested, manual-notes, residual-risks. We don't need to edit unless required. But should we fix trivial HTML issues? We have writer tools; but instructions: implement smallest correct change, only if task expects edits. The task says check, not fix. Could report. The acceptance report shape includes changedFiles; if no changes, empty array. But it also includes criteriaSatisfied. We can satisfy by validating and reporting. However to be safe, we might fix the actual errors/valid warnings: encode ampersand in title, add type="button" to menu button, add aria-label to nav elements. But the acceptance criteria didn't ask for fixing; but "check for errors" could include fixing if any. We need weigh. The user only asked check. As a subagent, we can return focused result. But maybe parent asked to execute task; the task from user (or parent) is to check HTML for errors. Since it is a delegated subagent, perhaps expected to produce an audit. We can mention no changes made. But the acceptance contract says "Completion is not accepted from prose alone. End with a structured acceptance report." So final must include JSON block. It doesn't require changes. We can include residual risks: unescaped ampersand, missing button type, duplicate nav landmarks, trailing slashes (cosmetic). We can also provide manual notes.

Let's inspect lines for raw ampersands to be precise.

Music & Sound

   144
Live instruments, sound journeys, and chanting. Music is medicine. It bypasses the intellect and speaks directly to the soul.

thinking:
Good. Raw ampersands at line 6 title, line 143 Music & Sound, line 179 circles & retreats. They are valid in HTML5 text? Actually the W3C validator did not flag them, perhaps because in HTML5 ambiguous ampersand only an error if followed by alphanumeric? Wait "Music & Sound": the ampersand is followed by space, so no parse error. The spec says unescaped ampersand is a parse error only when it's an ambiguous ampersand (followed by one of certain named char reference characters and not terminated by semicolon) or as part of an unrecognized character reference? For text content, `&` followed by space is okay. But best practice encode. html-validate has `no-raw-characters` rule requiring encode all `&`. Since project uses `—` entities, and uses HTML5 self-closing style, maybe the maintainer wants XHTML-like style. The instructions didn't mention validation. The question "check this html for errors"—the answer should report these findings. It is ambiguous whether to edit. Given acceptance contract no prose alone and maybe no changes. But we can offer to fix. The subagent should complete the task. Since no explicit fix instruction, but the task is just checking, returning report is appropriate. However to deliver value, we might fix the minor issues. But will parent expect changes? We need decide.

Let's inspect JS to ensure IDs present and no mismatch. JS uses revealElements, navLinks, menuBtn. The HTML has IDs: navbar, navLinks, menuBtn. Good. Anchor targets #home, #about, #practices, #retreats, #contact exist. Need check CSS links exist. main.css, responsive.css. Let's read quickly maybe.

thinking:
No issues. Need maybe verify page with headless? Not necessary. We have validation evidence. Need produce final with concise result, manual-notes, residual-risks, and acceptance-report JSON. The JSON fields: criteriaSatisfied, changedFiles (empty), testsAddedOrUpdated (empty), commandsRun (include html-validate and W3C validator), validationOutput, residualRisks, noStagedFiles? We didn't stage; true? If no git changes. diffSummary "No changes made". reviewFindings list issues. manualNotes optional string. For noStagedFiles true means no changes staged; okay.

Need mention commands result: html-validate failed due to style/a11y warnings; W3C validator passed (info only). But should we mark html-validate as failed? It returned exit code non-zero because of errors. But these aren't actual HTML errors. We can note as passed? Need be accurate. commandsRun[].result: exactly one of passed, failed, not-run. For html-validate, exit non-zero, but output is mostly style/a11y. We can mark failed with summary. W3C validator passed. For a local lint maybe failed. Or we could mark html-validate as passed? No, it exited with errors. But the task is "check for errors" so failed indicates issues found. We'll use failed. Maybe also run a simple structural check: all referenced asset files exist. That passed.

Need perhaps include a manual note: No code changes were made; issues are advisory. The W3C Nu validator reports only info-level trailing-slash notes. Syntax/parse is valid. Residual risks: raw ampersands may fail stricter XML/XHTML processing; menu button lacks explicit type; duplicate nav landmarks missing accessible names; self-closing slashes are cosmetic per HTML5 but inconsistent with project conventions? The instructions say static marketing site, no framework, not XHTML. Could mention trailing slashes are allowed but the site uses some void tags without slash (link preconnect lines 9-10 no slash) making it inconsistent. Actually line 9-10 link preconnect no self-closing slash; line 13-14 do have slash. So inconsistent style, not error. Good to note.

Should we decide to fix? The user asked "can you check this html for errors". If I only report, maybe enough. But as subagent with writer tools, maybe we should fix the real issues to deliver a "checked" HTML. However "check" is not "fix". The acceptance contract doesn't demand fixes. It demands "manual-notes, residual-risks". So report is fine. But the instructions say "If a delegated task expected code edits and you did not make them, do not return a success summary." This task didn't expect code edits. So no edits OK.

Let's verify W3C result count maybe read messages count. It has 13 info messages. No errors. Good.

Could also run `python3` to parse and ensure all tags closed. Let's do a quick script to verify using `html.parser` that no unclosed tags remain at EOF.

command:
cd /mnt/flash1/code/webpage && python3 - <<'PY'
from html.parser import HTMLParser
class P(HTMLParser):
    def __init__(self):
        super().__init__()
        self.stack=[]
        self.void={'area','base','br','col','embed','hr','img','input','link','meta','param','source','track','wbr'}
    def handle_starttag(self,tag,attrs):
        if tag not in self.void:
            self.stack.append(tag)
    def handle_endtag(self,tag):
        if tag not in self.void:
            if self.stack and self.stack[-1]==tag:
                self.stack.pop()
            else:
                print('mismatch:', tag, 'stack:', self.stack)
with open('index.html') as f:
    P().feed(f.read())
print('unclosed:', P().stack)
PY


text: unclosed: []


thinking:
Good. We can include that structural parse check passed. Now final response with JSON. Need ensure JSON block fenced tagged acceptance-report. Also note no code changes. Let's craft concise result.

Need not include hidden reasoning. Just final.

Let's double check noStagedFiles: We didn't use git, no changes. true.

Changed files: [].
Tests added or updated: [].
Commands run:
- npx html-validate index.html -> failed (19 rule hits: void-style, no-raw-characters, unique-landmark, no-implicit-button-type)
- W3C Nu validator via curl -> passed (only info-level trailing-slash notes)
- Python html.parser structural check -> passed (no unclosed/mismatched tags)
- Asset reference check -> passed (CSS/JS files exist)

Validation output: summarize W3C info 13 messages, html-validate 19 issues, structural parse OK.
Review findings:
- line 6: unescaped ampersand in `<title>` (should be `&`) — real markup hygiene issue
- lines 143 and 179: unescaped ampersands in headings (html-validate flags; W3C allows when followed by whitespace)
- line 28: menu `<button>` missing type="button" (a11y/behavior best practice)
- line 19 and 276: two `<nav>` landmarks without aria-label/aria-labelledby (a11y best practice)
- trailing slashes on void elements throughout (cosmetic; W3C info only; inconsistent because preconnect links omit them)
- No unmatched tags or missing closing tags.

Residual risks: Stricter parsers/XML may choke on raw ampersands; screen-reader users may not distinguish duplicate nav landmarks; menu button could submit if placed in a form later.

Manual notes: W3C considers document valid HTML5 (no errors/warnings). HTML-Validate's default style rule objects to XHTML-style self-closing void tags, which is a convention preference, not a validity error.

Need maybe mention no edits. Good.

text:
**HTML check results**

The document parses structurally clean (no mismatched or unclosed tags, all referenced CSS/JS files exist). The W3C Nu HTML validator reports **zero errors or warnings** — only 13 info-level notes about trailing slashes on void elements.

A stricter local lint (`html-validate`) flags 19 issues, most of which are style/a11y best-practice rather than HTML validity errors:

| Finding | Location | Severity |
|---|---|---|
| Unescaped `&` in `<title>` | line 6 | hygiene (stricter parsers) |
| Unescaped `&` in headings | lines 143, 179 | hygiene |
| `<button>` missing `type="button"` | line 28 | a11y / behavior |
| Two `<nav>` landmarks without unique accessible names | lines 19, 276 | a11y |
| Trailing `/` on void elements (`<meta>`, `<link>`, `<img>`) | many | cosmetic / style |

No code changes were made because the task was to check, not fix. Fixing the first three items is recommended if you want the file to pass stricter linters.
